DETAILED DESCRIPTION OF THE INVENTION

[0020] In order to provide a further understanding of the objective, characteristics and functions of the present invention, fully description is given below with a preferred embodiment and accompanying drawings. FIGS. 1 and 2 are schematic diagram of a preferred embodiment of the present invention. The present invention is an organic polymer waste material disposal device, mainly composed of a flue gas circulation system, poor-oxygen cycle de-polymerization device 1, an oil-gas separation system and a waste residue collection system. Wherein the poor-oxygen cycle de-polymerization device 1 is divided into an inner chamber 11 and an outer chamber 12, the inner chamber 11 being an alloy annular plate, the outer chamber 12 being made of heat-resistant concrete, the outer layer of which is added with a layer of metal reinforcement ring. The feed end of inner chamber 11 of the weak oxygen cycle de-polymerization device 1 is connected with the mixing portion 13, while the discharge end of the inner chamber 11 is connected with the separation portion 14 and the poor-oxygen cycle de-polymerization device 1 is provided with a U-shaped pipeline 10 to communicate with the outer chamber 12. The U-shaped pipeline 10 is connected to the outer chamber 12 of multi-section poor-oxygen circulation de-polymerization device 1 by splicing. The mixing portion 13 is provided with a storage bin 21, a vibratory feeder 22 and a screw conveyor 23 from top to bottom. The screw conveyor 23 passes through the mixing portion 13 and the poor-oxygen cycle de-polymerization device 1. Namely, the polymer materials drop into the vibratory feeder 22 from the storage bin 21 (particle size of the polymer materials controlled at 0-15 mm). The polymer materials enter the screw conveyor 23 which conveys the materials to the mixing portion 13 where the materials are mixed with low temperature poor-oxygen gas (low temperature poor oxygen or anaerobic gas at the temperature of 400-500 DEG C.), passes through the poor oxygen cycle de-polymerization device 1 for reaction under the impetus of the screw conveyor 23. In this part, the flue gas circulation system sends the low temperature poor-oxygen gas to the inner chamber 11 to have de-polymerization reaction with the polymer materials, and sends the high temperature flue gas to the outer chamber 12, the high temperature flue gas enters the flue gas circulation system again after passing through the outer chamber 12, the gas and waste residues respectively enter the oil-gas separation system and the waste residue collection system after reaction in the inner chamber 11. Wherein, the movement direction of the high temperature flue gas in the outer chamber 12 is opposite to that of the low temperature gas and the polymer materials in the inner chamber 11, forming shear temperature difference, which accelerates the reaction of the materials in the inner chamber 11.

[0021] The flue gas circulation system mainly comprises a gas generating furnace 31, a first heat exchanger 32, a second heat exchanger 33 and a flue gas scrubber 34, the second heat exchanger 33 absorbing air with the help of the first induced draft blower 41 and discharging clean flue gas with the help of the second induced draft blower 42, the gas generating furnace 31 being connected with the blast-proof water block 30. The air enters the second heat exchanger 33 for heating and enters the combustion chamber of the gas generating furnace 31 for combustion. The gas generating furnace 31 is charged with anthracite and water to react, and the generated flue gas meets with the heated air in the first heat exchanger to produce high temperature fuel gas, which passes through the outer chamber 12 and enters the second heat exchanger 33 for cooling (while the air at room temperature can be heated up) and the flue gas scrubber 34 for dedusting before being discharged, and the discharged air is clean. Wherein the flue gas burned in the first heat exchanger 32 is subjected to heat exchange with the partially reacted low hydrocarbon combustible gas and the resulting low temperature anaerobic gas enters the mixing portion 13 for mixing and reacting with the polymer materials.

[0022] The above-mentioned oil-gas separation system mainly includes a cyclone separator 51, at least one condenser 52, an oil-water separator 53 and a buffer tank 54. The oil and gas formed by the reaction in the inner chamber 11 of the poor oxygen cycle de-polymerization device 1, after being dedusted by the cyclone separator 51, enters the condenser 52 for cooling; the oil enters the oil-water separator 53 for separation; when there are multiple oil-water separators 53, an blending oil transition tank can be arranged to for collection in unison and the gas is a low hydrocarbon combustible gas, part of which passes through the buffer tank 54 and enters other equipment (such as reverberatory furnace and blast furnace). The preferably low hydrocarbon combustible gas exiting from the buffer tank 54 passes through the Roots circulation blower 50 and the fire arrestor 55 before entering the first heat exchanger 32 and other equipment for use, while the other portion of the low hydrocarbon combustible gas enters the first heat exchanger (32) for heating before being sent to the mixing portion (13). Wherein the lower portion of the cyclone separator 51 is connected with the waste residue collection system to sediment the particles in the oil and gas which enter the waste residue collection system in the company of the slag discharged from the poor-oxygen cycle de-polymerization device 1 for disposal.

[0023] The above-mentioned waste residue collection system mainly includes a cooling humidifying pipeline 61, an exhaust pipe 62 and a dust collector 63; the separation portion 14 is connected with the cooling humidifying pipeline 61. After carrying out cooling treatment to the slag produced by the reaction in the poor-oxygen cycle de-polymerization device 1, the metal-containing waste residue can be used to extract metal in the smelting workshops; the dust collector 63 is located on the exhaust pipe 62 to further dedust gas produced during the cooling of the waste residue by spraying before the gas is discharged into the air.
