BEST MODE FOR CARRYING OUT THE INVENTION

[0018] The invention is explained in more detail below by the example method using reference to the accompanying figures; including:

[0019] Figure FIG. 7 is showing the filter with two solution compartments 3 and 4, in which, compartment 4 acts as a mixing compartment/mixing chamber, which contains the structure/cluster of structures of the filtration equipment, compartment 3 acts as air path and compensation solution container; mixing compartment/chamber 4 has a vertical cylinder with a circular cross-section with the height size ratio on diameter L4/D4˜3; diffusing structure/mixing structure 9 includes the cone 91 with cone-shape with vertex facing down, made from thin material sheets with perforated holes over its entire area, arranged to be submerged in the cleaning solution, with the edges on the surface of the solution approximately H1, the cone 91 is arranged to rotate around its center axis due to the shaft 92 that is driven by a motor and speed reducer box 93 fixed on top of the mixing chamber. The dehumidifier structure 8 is made of moisture-sensitive material sheets staggered slanting with bottom edge facing outward diameter, the dehumidifier structure is arranged above the surface of the solution and has the lowest part of the bottom layer from the surface of a solution approximately H2. Above the dehumidifying layer is the activated carbon

layer that has the final filtering task before releasing the product to the environment. Port 6 is the location for serial installation of the next mixing chamber when there is a need for higher filtration quality.

[0020] Cone 91 with cone shape has a line that produces angle B with respect to the horizontal has the function of increasing the area of the diffuser compared to the same size mixer. The inclination angle B is in the range of 15-60 degrees, if this angle is too large, it will affect the size of the mixing chamber (increase the size of the mixing chamber) and affect the ability to distribute the airflow evenly across the entire working surface of the mixing structure; if this angle is too small, the diffusion efficiency will be reduced due to insufficient diffusion area.

[0021] The fact that the cone 91 rotates around its center axis helps dispersing the air bubbles, blending them into cleaning solution more thoroughly. The optimum rotation speed is in the range of 142-157 rounds/minute. If the rotation speed is too large, it will create eddy current, making it difficult for bubbles to pass through the meshes of the cone 91; if the rotation speed is too small, it will reduce the effect of air bubbles dispersion.

[0022] According a plan as showing in figure FIG. 9, the edges of holes in the cone 91 have a wing shaped like a pump impeller, creating an angle J in compared to the tangent of the rotation of the cone 91. The wings 991 when rotating will help dispelling the air bubbles and mixing them with cleaning solution more effectively.

[0023] According to other plan as showing in figure FIG. 10, the entire of wings 991 create an angle J in compared to the tangent of the rotation of the cone 91.

[0024] To create kinetic energy for the air flow that need to be cleaned, we use an air supplying structure 2 including a fan driven by an electric motor. To increase the speed and performance of the device, we use exhausting fan

assembly 5 including motors and exhausting fans. Membrane filtration that prevents large dust particles as well as undesirable harmful materials/agents to the device ds arranged at the input of the device, before the air supplying structure 2.

[0025] To reduce the cleaning liquid losses due to evaporation effect, we use condenser unit assembly in order to cool the air to reduce the temperature of the air being fed into the device, this cooling condenser unit assembly is located on the inlet air intake (after the membrane filtration).

[0026] The operation of the device: when the device operating, the polluted air is sucked through the membrane filtration by the air supplying structure 2, then filled into compartment 3, and followed the 34 path between compartment 3 and compartment 4 to compartment 4. Due to the kinetic energy of the air stream, the air will split into air bubbles moving upwards. Diffusion structure 9 is responsible for dispersing the air stream to mix with the cleaning solution. The inclined wings 991 help dispersing air bubbles in solution to be more active and thorough, the dust in these air bubbles is retained in the cleaning solution, and the clean air moves up the surface of the solution.

[0027] The air after leaving the surface of the solution will have very high humidity, even carrying steam and small particles of water; the dehumidifying structure 8 is responsible for capturing the water vapor and water particles, drying the finished air going through it. The amount of steam retained at the dehumidifying structure 8 will follow inclined walls to spread out to the side walls of the device, then flows downwards.

[0028] The activated carbon layer 7 is the final filter structure; it is responsible for deodorizing and retaining bacteria.

[0029] To make the cleaning/washing of dust more effective, the distance H1 from the upper edge of the diffuser structure cone 91 to the surface of the

cleaning solution is in the range of 50-100 mm. If the distance is too small, the cleaning effect will not be achieved because the path of air bubbles in the solution is too small, if it is too large, bubbles will accumulate together, which will reduce the cleaning effect.

[0030] To make the dehumidifying structure works more effectively, the lower part of the dehumidifying structure should be away from the surface of the cleaning solution a distance of H2˜100-150 mm This distance is sufficient for most of the solution particles after splashes off the solution surface run out of kinetic energy, dropping and returning to the surface of solution. If the distance is too small, the particle of the solution will follow' inertia to latch on the lower part of the dehumidifying structure, which will reduce the effectiveness of the dehumidifying structure. If this distance is too large, it will unnecessarily increase the size of the device. The dehumidifying structure when filled with the solution will create a flow along the inner wall of the mixing chamber and return to the amount of cleaning solution below.

[0031] When the device operating, dust in the air will be retained in the cleaning solution, a large amount of them will stick to the inside walls of the device near to the surface of the cleaning solution. To clean the internal surface of the device near the surface of the solution, the air supplying structure 2 can be used with on/off method so that the solution from compartment 3, passing through the path 34 causes the solution in compartment 4 to rise/lower to wash away the dust sticking on the inside walls of the device.

[0032] For the function of washing clinging dust more effectively, the ratio of the cross-sectional area of compartment 3/compartment 4 is in the range: S2/S4—1/5-2/5. If this ratio is too large, it will affect the capacity of the air supplying structure, if it is too small, it will not work to clean the dust sticking on the inside walls.

[0033] When the device operating, dust in the air will be retained in the cleaning solution. After a period of working time (one working cycle) this solution should be cleaned and be replaced periodically. To accomplish this function, the mixing chamber 4 has a funnel-shaped bottom with the lowest part connected to filter 45 and the circulating pump system 46. After a working cycle (the cycle is installed in the controller), the solution is circulated through the filter by means of a pump system and flow control valve. After several working cycles the solution should be replaced.

[0034] FIG. 8 is showing the filter equipment by another option. According to this plan, the mixing chamber 4 should be split into chamber 41 and 42 connecting by the path 32. The mixing structure 9 is installed in the chamber 41, the dehumidifying structure and the activated carbon layer should be arranged in the chamber 42. Air after being released onto the surface of solution in the mixing chamber 41 will pass through the space 41 1 before following path 32 to the mixing chamber 42. The spacing 411 helps to retain maximum of the solution particles shot up from the surface of the solution in the mixing chamber 41, and the air passing through the mixing chamber 42 will be cleaned again by the solution in before being released to the environment.
