As shown in fig. 1 and 2, in the initial state of the present invention, the electric heating tubes RT and RT1 are heated to heat the inside of the outer cylinder 113, and can respectively perform heating decomposition on the paint waste residue materials in the two inner cylinders 114 in an anoxic state (the hot gas can simultaneously act on the periphery of the inner cylinders 114, so as to ensure that the paint waste residue in the inner cylinders 114 is uniformly heated and decomposed); under the action of external heat, the external flameless heat energy breaks the chemical bonds of the paint waste residue compounds in the inner cylinder 114, the paint is converted from large molecular weight organic matters into small molecular weight combustible gas, the small molecular weight combustible gas enters the combustible gas treatment equipment 12 through the gas outlet pipes 112 at the upper ends of the two inner cylinders, then enters the interior of the spiral pipeline 122 through one end of the lower part of the spiral pipeline 122, and then enters the gas utilization equipment in the production area from one end of the upper part of the spiral pipeline 122 for combustion (for example, the gas is used as combustion gas for boilers of manufacturers, gas for processing food by catering parties of manufacturers, and the like), so that the combustible waste gas generated in the pyrolysis process of the paint waste residue can be. The water in the water tank 121 of the combustible gas treatment device 12 can cool the combustible gas in the spiral pipeline 122, so that support is provided for the gas equipment in the subsequent production area, and the damage of the sealing rubber piece of the valve and the like caused by the overheated gas entering the gas equipment pipeline and the valve in the production area is prevented. When the water tank 121 is full of water, the water level switch SD of the combustible gas treatment device 12 has two normally open contacts therein in an open state, and the positive power supply input end of the relay J3 is not electrified and is not attracted; when the water level in the water tank 121 is reduced, the two normally open contacts inside the floater of the water level switch SD, which are reduced by the buoyancy of water, are in a closed state, so that the positive power input end of the relay J3 obtains power from the 3 pins of the switching power supply A1 through the two normally open contacts inside the water level switch SD, which are closed at this moment; because the negative power input end of the relay J3 is communicated with the 4 feet of the switch power supply A1, the control power input end of the relay J3 is communicated with the 3 feet of the switch power supply A1, the normally open contact end of the relay J3 is connected with the positive power input end of the DC of the electromagnetic water valve, and the DC negative power input end of the electromagnetic water valve is communicated with the 4 feet of the switch power supply A1, the DC of the electromagnetic water valve can be used as an electric tool to open the inner valve core at the moment; thus, the tap water flowing out of the tap water pipe 123 enters the tank to fill the tank 121 with water. When the water level in the water tank 121 rises again, the float of the water level switch SD is subjected to buoyancy of water to become large, and the two internal normally open contacts are in an open circuit state again, so that the positive power input end of the relay J3 can not get power supply from the 3 pins of the switching power supply a1 through the two internal normally open contacts of the water level switch SD, and thus, the relay J3 can lose power and no longer attract the control power input end and the normally open contact end to open a circuit, and further, the electromagnetic water valve DC loses power and the valve core is closed, and water in the tap water pipe 123 can not enter the water tank 121 again. Through the above, the water level in the water tank 121 can be always kept at a certain depth, and the water level in the water tank 121 is ensured to be suitable for effectively cooling the hot combustible gas in the spiral pipeline 122. The utility model discloses about one hour thermal cracking process, the interior paint waste residue of interior barrel 114 can be by effective pyrolysis carbonization. After cracking, the operator turns on the control power switch of the electric screw conveyor 2 again, so that after the two sets of electric screw conveyors 2 are powered on to work, the rotating electric screw conveyor auger 22 conveys the paint waste residue in the inner cylinder 114 forward to leak out through the waste residue pipe 116 to enter the slag box 6 (the waste gas in the slag box 6 enters the waste gas treatment equipment through the connecting pipe 63 to be treated); when the time is about three minutes, after a small amount of paint waste residues enter the residue box 6 after all carbonization, an operator can repeat the steps, the control power switches of the two sets of electric rotary valves 3 and the two sets of electric screw conveyors 2 are opened, and then the paint waste residues in the material box 4 respectively enter the two inner cylinder bodies 114 again to carry out pyrolysis carbonization reaction, so that the continuous circulation is realized, and the operator can continuously carry out pyrolysis treatment on the paint waste residues entering the material box 4. In practical use, because the volume of the slag box 6 is limited, after the slag box is used for a period of time (generally one week), the movable door 61 is opened, and the carbonized slag which is harmless to the environment is cleaned and buried, and the normal operation of production is ensured.

As shown in fig. 2, when the control power switches S1 and S2 are turned on, the electric rotary valve M and the electric screw conveyor M1 are powered on to operate, and when the control power switches S1 and S2 are turned off, the electric rotary valve M and the electric screw conveyor M1 are powered off to stop operating.
