DESCRIPTION OF IMPLEMENTATION
[0039] The present invention makes public the method for revalorization of various organic waste, this method will be described in detail below, combined with examples.
[0040] Example: a method for revalorization of various organic waste, first, enter the fluid mixture of organic matter and water (hereafter referred to as “mixture”) in a hermetically sealed treatment tank, in which the pressure is negative while maintaining low temperature. The bubbler produces gas bubbles that inject to the mixture and vigorously stir the mixture in the sealed treatment tank under depressure, then establish the movement of toric rotation in the vertical direction in the mixture. If there is a requirement to kill the active bacteria, the sealed treatment tank will maintain a temperature between 20 and 30 degrees Celsius. Otherwise, the low temperature remains between 10 and 40 degrees Celsius.
[0041] In this example, during the movement of toric rotation in the vertical direction of the mixture, the high-speed movement bubble carrying focused energy vigorously collide into the mixture, thus showing the Rheo-fluidizing effect (Shear thinning), decrease the viscosity of the mixture, and depolymerize long-chain molecules in organic waste.
[0042] If grease emulsion is present in the mixture, at this time de-emulsifying occurs, separating oils and fats. This happens while, because of depressure, if present, bacteria are killed. Spores and inactive bacteria remain in the small quantity of grease mixed in the organic matter. Finally, organic matter is separated into water soluble substances, higher-density than water insoluble substances and lower-density than water insoluble substances. The soluble substances will dissolve into the water, the higher-density insoluble substances will decant to the bottom of the container, and the lower-density insoluble substances will float on top of the water level. This achieves active bacteria killing, separation, concentration and de-emulsification.
[0043] In this example, the described mixture is obtained by means of mixing evenly the organic waste and water.
[0044] The present invention also makes public an apparatus for the revalorization of various organic waste, this apparatus will be described in detail below, combined with examples.
[0045] Example 1:
[0046] A suction pipe 9 installed on the upper of the treatment tank 1 connects to the interior of the treatment tank. The mixture entering the treatment tank situates lower than the position of the suction valve. The vacuum pump 3 has an inlet and an exhaust outlet. The former is called the first inlet. This first inlet connects to the suction line through the suction pipe 9. The suction pipe 9 has installed on it an inlet valve 10, which controls the opening and closing of the suction pipe 9, causing the first inlet and the suction valve to be either connected or disconnected.
[0047] The exhaust outlet of the described vacuum pump 3 is connected to two outlet pipes. the two outlet pipes are called the first exhaust outlet pipe 11 and second outlet pipe to the bubbler 12 respectively. The second vent valve 13 is installed on the first exhaust outlet pipe 11. The vent valve 13 is used to open and close the first exhaust outlet pipe 11. The lower part of treatment tank 1 has an inlet connected to the interior of the treatment tank. This inlet is called the second inlet. The described second outlet pipe to the bubbler 12 is connected to the second inlet. The described inlet valve 5 is installed on the described second outlet pipe to the bubbler 12, and it is used to open or close the described second outlet pipe to the bubbler 12, causing the second outlet pipe to the bubbler 12 and the second inlet to be either connected or disconnected.
[0048] The treatment tank 1 has installed the first discharge outlet which is connected to its interior. At the first discharge valve 14 is installed on the first outlet, which controls the opening and closing of the first outlet. The bubbler is installed on the interior of the tank, facing the second inlet. The described hermetically sealed treatment tank 1 has negative pressure while maintaining low temperature. The bubbler 4 produces gas bubbles that inject to the mixture and vigorously stir the mixture in the sealed tank under depressure, then establish the of toric rotation in the vertical direction in the mixture.
[0049] The prepared the fluid mixture of organic matter and water inside the treatment tank 1 rise along the inner wall of the hermetically sealed treatment tank, and flow down in the center part of sealed treatment tank, re-rise again along the inner wall of the treatment tank, and the cycle continues, following the trajectory of the movement (see the
[0050] During the movement of toric rotation in the vertical direction of the mixture, the high-speed movement bubble carrying focused energy vigorously collide into the mixture, thus showing the Rheo-fluidizing effect (Shear thinning), decrease the viscosity of the mixture, and depolymerize long-chain molecules in organic waste.
[0051] If grease emulsion is present in the mixture, at this time de-emulsifying occurs, separating oils and fats. This happens while, because of depressure, if present, bacteria are killed. Spores and inactive bacteria remain in the small quantity of grease mixed in the organic matter. Finally, organic matter is separated into water soluble substances, higher-density than water insoluble substances and lower-density than water insoluble substances. The soluble substances will dissolve into the water, the higher-density insoluble substances will decant to the bottom of the container, and the lower-density insoluble substances will float on top of the water level. This achieves active bacteria killing, separation, concentration and de-emulsification. The movement of toric rotation in the vertical direction of the mixture lasts 15 minutes, after then, decantation is needed for 15 minutes.
[0052] In this example,
[0053]
[0054] In this example, the diameter of the perforation 45 is ⅛ inches.
[0055] In this example, the angle θ1 between the vertical axis and direction of injection of the nozzle is 26.5 degree.
[0056] In this example, a linear accelerator is placed between the second outlet pipe 12 to the bubbler and the second inlet. This described accelerator is implemented with a converging tube, with an angle of convergence of the tube between 69 degrees.
[0057] In this example, the vacuum inside of treatment tank 1 is 0.75-0.85 bar. In this example, the treatment tank 1 has the cylinder shape, the diameter and height of the treatment tank 1 have ratio is 2/5.
[0058] In this example, the mixture of organic waste and water entering the treatment tank 1 takes up 75% of the volume of the treatment tank.
[0059] In this example, the mixture is that of the pig manure and water, there is a requirement to kill the active bacteria, while the low temperature is 20° C.-30° C.
[0060] Towards the treatment of pig manure using the apparatus for revalorization the various organic waste, open the feed input 2 and the first vent valve 8, then the inlet valve 10, inlet valve 5 to the bubbler, the second vent valve 13 and the first discharge outlet valve 14, while the treatment tank 1 is at ambient pressure, enter the pre-prepared fluid mixture of pig manure and water into treatment tank 1, then close the feed input pipe 6 and the first vent valve 8; then open the inlet valve 10 to the vacuum pump and the second vent valve 13, start the vacuum pump 3 to partially evacuate the treatment tank 1 above the mixture and the evacuated gas exhausted through the first exhaust outlet pipe 11, until the vacuum reaches the preset depressure and hold at this preset vacuum for typically 3 minutes to remove methane following the death of active bacteria. At this time, close the second vent valve 13, open inlet valve to the bubbler 5, the evacuated gas enters the bubbler 4 by the second outlet pipe to the bubbler 12. The bubbles with negative pressure are produced in bubbler 4 and are injected into the mixture and vigorously stir the mixture in the sealed tank 1 under depressure, then establish the movement of toric rotation in the vertical direction in the mixture.
[0061] During the movement of toric rotation in the vertical direction of the mixture, the high-speed movement bubble carrying focused energy vigorously collide into the mixture of pig manure and water, thus showing the Rheo-fluidizing effect (Shear thinning), decrease the viscosity of the mixture of pig manure, and depolymerize long-chain molecules in pig manure.
[0062] Grease emulsion and bacteria are present in the mixture of pig manure. De-emulsifying occurs, separating oils and fats. This happens while, because of effect of depressure, active bacteria are killed. Spores and inactive bacteria remain in the small quantity of grease mixed in the organic matter. This achieves active bacteria killing, separation, concentration, de-emulsification.
[0063] Finally, the mixture of pig manure and water is separated into three layers, the top layer composes of greasy substances including the oils and fats (oil phase), the middle layer is of soluble substances dissolved into the water (liquid phase), the bottom layer is organic matter separated from pig manure and decanted to the bottom of container (solid phase). The separation of mixture of pig manure and water is terminated. Close the inlet valve 10 and vacuum pump 3, open the first vent valve 8, restore the ambient pressure in the treatment tank 1. After 15 minutes of decantation, using existing technology, one obtains the oil phase, liquid phase and solid phase, which can now be recycled and reused for further purposes.
[0064] Comparing the other poultry manure or plant residue, the pig manure contains a large amount of grease emulsion and water, thus most difficult to treat. Through the treatment of pig manure with the present invention of apparatus for revalorization of various organic waste, one can infer further applications of the present invention to the revalorization of various organic waste and manure such as poultry manure. The most optimal reusage of the produce is in organic fertilizing.
[0065] The present solution is totally different from the traditional fermented compost which takes over two weeks of processing. When the apparatus for the revalorization of various organic waste provided by the presentation invention treats the pig manure, it has a short processing cycle, an efficient way of revalorizing organic waste without producing unpleasant odors and non-polluting, the recovery rate the organic matter reaches up to 95% without destroying the microorganisms and nutrients while only 35%-50% for the traditional recovery, the final product could be the organic fertilizer of corresponding specifications according to the needs, in order to meet the needs of crop growth and soil for different NPK and trace elements. As most of organic matter is recovered, very few waste gas and liquid produced during the operation, it can be controlled under the local regulation of discharge, void of pollution. The technology of the present invention carries advantages comparing the traditional solutions. After being degreasing and cold-dried while consuming little energy, the organic fertilizer is stable, dry, and clean, it could be conserved for long time, transportation of it is simple, making it easily suitable for subsequence processes. Therefore, the apparatus for the revalorization of various organic waste of present invention pushes the cycle of organic matter towards an ecological path, in addition to having a wide range of potential applications.
[0066] Example 2: this example is essentially the same as example 1, the difference is: In this example, the organic waste is kitchen waste, and it is intended to produce organic fertilizer. There is no grease emulsion in the kitchen waste, but it contains oil, so oil separation is needed. The movement of toric rotation in the vertical direction of the mixture of kitchen waste and water lasts 10 minutes. After completing the movement of toric rotation in the vertical direction of mixture of kitchen waste and water, the decantation lasts 10 minutes.
[0067] In this example, the diameter of the perforation 45 is ⅛ inches.
[0068] In this example, the angle θ1 between the vertical axis and direction of injection of the nozzle θ1 is 26.5 degree.
[0069] In this example, a linear accelerator is placed between the second outlet pipe to the bubbler 12 and the second inlet. This described accelerator is implemented with a converging tube, with an angle of convergence of the tube between 69 degrees.
[0070] In this example, the vacuum inside of treatment tank 1 is 0.75-0.85 bar. In this example, the treatment tank 1 has cylinder shape, the diameter and height of the treatment tank 1 have ratio is 2/5.
[0071] In this example, the mixture of organic waste and water entering the treatment tank 1 takes up 67% of the volume of the treatment tank.
[0072] In this example, the mixture is that of the kitchen waste and water. there is a requirement to kill the active bacteria, while the low temperature is 20° C.-30° C. Natural waste food has different shapes and sizes. According to the needs of organic fertilizer production, the mixture needs to be shredded into small particle in 5 mm before mixing with water.
[0073] Towards the treatment of kitchen waste using the apparatus for revalorization the various organic waste, first open the feed input 2 and the first vent valve 8, then close the inlet valve 10 to the vacuum pump, inlet valve 5 to the bubbler, the second vent valve 13 and the first discharge outlet valve 14. While the treatment tank 1 is at ambient pressure, enter the pre-prepared fluid mixture of pig manure and water into treatment tank 1, then close the feed input pipe 6 and the first vent valve 8; then open the inlet valve 10 to the vacuum pump and the second vent valve 13, start the vacuum pump 3 to partially evacuate the treatment tank 1 above the mixture and the evacuated gas through the first exhaust outlet pipe 11, until the vacuum reaches the preset for typically 3 minutes to remove methane following the death of active bacteria. At this time, close the second vent valve 13, open the described inlet valve 5, the evacuated gas enters the bubbler 4 by the second outlet pipe to the bubbler 12. The bubbles with negative pressure is produced inside the bubbler 4, inject into the mixture and vigorously stir the mixture in the sealed tank 1 under depressure, then establish the movement of toric rotation in the vertical direction in the mixture.
[0074] During the movement of toric rotation in the vertical direction of the mixture of kitchen waste and water, the high-speed movement bubble carrying focused energy vigorously collide into the mixture of pig manure and water, thus showing the Rheo-fluidizing effect (Shear thinning), decrease the viscosity of the mixture of kitchen waste, and depolymerize long-chain molecules in kitchen waste.
[0075] Because of effect of depressure, active bacteria are killed. Spores and inactive bacteria remain in the small quantity of grease mixed in the organic matter. This achieves active bacteria killing, separation and concentration.
[0076] Finally, the mixture of kitchen waste and water is separated into three layers, the top layer composes of greasy substance including the oil and fats (oil phase), the middle layer is of soluble substance dissolved into the water (liquid phase), the bottom decanted layer is of organic matter separated from kitchen waste (solid phase). The separation of mixture of kitchen waste and water is then terminated, close the inlet valve 10 and vacuum pump 3, open the first vent valve 8, restore the ambient pressure in the treatment tank 1. After 10 minutes of decantation, using existing technology, one obtains the oil phase, liquid phase and solid phase, which can now be recycled and reused for further purposes.

[0083] The described bubbler 4 is located inside of major tank 1a, the mixture of the organic waste and water in major tank 1a is separated into water insoluble substances with lower-density than water insoluble substances which is fiber-rich organic matter-based floating matter, the soluble substance, and the insoluble substance with higher-density than water insoluble substances which is residue.
[0084] The apparatus for the revalorization of various organic also contains the brush conveyor 1g, the endless screw outlet for residue 1h and the endless screw outlet for fiber-rich organic matter 1j. The brush conveyor 1g is horizontally installed above the lip overflow 1c and extends from the upper part of major tank 1a to that of the auxiliary tank 1b.
[0085] The brush conveyor 1g is used to sweep the fiber-rich organic waste whose liquid level reaches the lip overflow 1c, from the major tank 1a to auxiliary tank 1b. The endless screw outlet for fiber-rich organic matter 1j is installed on the bottom of auxiliary tank 1b, facing the second outlet, it is used to output the fiber-rich organic matter from auxiliary tank 1b while the second output valve if opens.
[0086] The endless screw outlet for residue 1h is installed on the bottom of the major tank 1a, facing the first outlet. It is used to output the residue of the major tank while the first discharge outlet valve 14 opens. The described water inlet is used to input the water to the major tank 1a to raise the liquid level to lip overflow 1c, and the fibre-rich organic matter can be swept into the interior of the auxiliary tank 1b by the bush conveyor 1g.
[0087] In this example, the mixture of organic waste and water entering the major tank 1a takes up 65% of the volume of the major tank 1a.
[0088] In this example, the major tank 1a has the rectangular shape, the equivalent diameter and height of the major tank 1a have ratio is 2/5.
[0089] In this example, the mixture is paper mill sludge which is the acidic fiber-rich organic waste and water, there is no requirement to kill the active bacteria, the low temperature is 10° C.-40° C.
[0090] During the treatment of fiber-rich organic waste using the apparatus for revalorization the various organic waste, open the feed input valve 2 and the first vent valve 8, then close the inlet valve 10 to the vacuum pump, inlet valve 5 to the bubbler, the second vent valve 13 and the first discharge outlet valve 14, the second discharge valve if and water inlet valve 1e. At this time, the major tank 1a and auxiliary tank 1b are ambient pressure. Enter the pre-prepared the fluid mixture of fiber-rich organic matter and water into major tank 1a via the feed input 6, then close the feed input 6 and the first vent valve 8. Then first open the inlet valve 10 to the vacuum pump and the second vent valve 13, start the vacuum pump 3 to partially evacuate the major tank 1a above the mixture of fiber-rich organic waste and entirely evacuate the auxiliary tank 1b. The evacuated gas exhausts through the first exhaust outlet pipe 11, until the vacuum reaches the preset depressure and hold at this preset vacuum for typically 3 minutes to remove methane following the death of active bacteria. Close the second vent valve 13, open the inlet valve 5 to the bubbler. At this time, the evacuated gas goes through the second outlet pipe 12 to the bubbler 4. The bubbles with negative pressure are produced in the bubbler 4 inject to the mixture and vigorously stir the mixture in the major tank 1a under depressure, then establish the movement of toric rotation in the vertical direction for 10 minutes in the mixture.
[0091] During the movement of toric rotation in the vertical direction of the mixture of fiber-rich organic waste, the high-speed movement bubble carrying focused energy vigorously collide into the mixture of pig manure and water, thus showing the Rheo-fluidizing effect (Shear thinning), decrease the viscosity of the mixture of fiber-rich organic waste, and depolymerize long-chain molecules in fiber-rich organic waste.
[0092] Finally, the mixture of fiber-rich organic waste is separated into three layers, the fiber-rich organic matter is on the top layer, the middle layer is soluble substance dissolved into the water, the bottom layer is residue. the separation of mixture of fiber-rich organic waste and water is terminated. Close the described inlet valve 10 and vacuum pump 3,
[0093] Open the water inlet valve 1e, enter the water to major tank 1a through the water inlet pipe 1d in order to raise the liquid level to lip overflow 1c, then stop the water input once the liquid is in contact with the brush conveyor 1g. The brush conveyor 1g sweeps the fiber-rich organic matter into the interior of auxiliary tank 1b.
[0094] In the case where there still fiber-rich organic matter remaining in the major tank 1a which is lower than the lip overflow 1c, input the water again to major tank 1a through the water input tube 1d, until all the fiber-rich organic matter is transported to the auxiliary tank 1b.
[0095] Afterwards, open the first vent valve 8, restore the ambient pressure in the tank 1a and 1b; open the first discharge outlet valve 14 and the second discharge outlet valve 1f, open the endless screw outlet for fiber-rich organic matter 1j and endless screw outlet for residue 1h. The fiber-rich organic matter is output by the endless screw outlet for fiber-rich organic matter 1j and the residue is output by the endless screw outlet for residue 1h. Then close the first discharge valve 14 and the second discharge valve 1f.
[0096] Fiber-rich organic waste usually refers to organic waste containing valuable cellulse, which mainly comes from paper mill residue such as paper mill sludge (including landfilled paper mill sludge). The application of fiber-rich organic matter recycling in the textile industry is also increasing. More and more widely, fiber-rich organic residue comes from textile production such as cotton, linen, bamboo; and agricultural residue such as corn, straw and other organic matter are also containing cellulose. An efficient recovery of fiber-rich organic matter and revalorization are an important pillar in the industry of reusage of fiber-rich organic matter. Moreover, it often reduces the cost of the original production (textile, paper) and pollution.
[0097] The apparatus for the revalorization of various organic waste provided by the present invention, using physics and mechanics, does not make use of any additional chemicals. The quality of the recovered organic matter is same as its entrance. The recovery rate is up to 99%. Through separation on the organic matter from the residue, separation and cleaning, the recovered organic matter acquires the second life. With under an hour in the treatment tank, the organic matter is separated and purified by means of Rheo-fluidizing effect (shear thinning) while the bubbles vigorously stir under depressure, and the wood chips, soil, stone in the mixture increase the stirring force for better cleaning. The solution of present invention helps avoiding additional pollution during the production.
[0098] In addition, the apparatus for the valorization of various organic waste provided by the present invention operates at low temperature, requires low energy consumption, has a compact layout and installation. Depending on the required volume of treatment, the equipment could be installed in the commercial building or in a factory building, it can also be installed in the open air, or in a movable loading truck. The scalability and integration are pretty flexible, with little size requirement on the area of site. If necessary, it can be transplanted on the bypass of the existing production line without affecting the actual production.
