[0036] The working principle and use process of this utility model:

[0037] When in use, raw materials are added into the preheating chamber 2 through the feeding port, the raw materials are preheated by the electric heating device, and the raw materials are dried and prepared for carbonization. After the preheating is completed, the control valve is opened to send the raw materials into the carbonization chamber 4, and the boiler room combustion heat source carbonizes the raw materials in the carbonization chamber 4. After the carbonization is completed, the control valve is opened to send the carbonized material into the activation chamber 5, and the boiler room combustion heat source continuously heats the activation chamber 5. At this time, the steam input pipe 7 is connected to the steam boiler, and the steam passes through the steam input pipe 7 through the steam absorption heat Mechanism 8, then enters the activation chamber 5 through the steam output pipe 9, activates the carbonized material in the activation chamber 5, and after the activation is completed, the control valve is opened, and the activated material enters the cooling chamber 6 for cooling. In the above process, since the preheating treatment takes a short time and the carbonization treatment time is long, the preheating chamber 2 continues to work, and the treated raw materials can be sent to the reserved chamber 3 for reservation. When the material treatment in the carbonization chamber 4 is completed, the control valve can be opened to replenish the material in the carbonization chamber 4 in time to increase the continuity of the carbonization treatment. When the activated material enters the cooling chamber 6, the activated material enters the cooling chamber 6. After cooling in the cooling chamber 6, the heat absorbing plate 82 can contact the activation material to absorb heat. When water vapor is generated in the boiler, due to the high load of the boiler and the high pressure in the boiler, as well as the heat loss during transportation, the water vapor will be mixed with atomized droplets. These atomized droplets directly enter the activation chamber 5, absorb the heat in the activation chamber 5, increase the pressure in the boiler room, and fail to perform the activation reaction in time. After the heat absorbing plate 82 absorbs heat, it can act on the water vapor passing through the inside. When the activation material is above 100 degrees Celsius, it can continue to act on the heat absorbing plate 82 to promote the absorption. The atomized droplets in the water vapor passing through the hot plate 82 are gasified, thereby reducing the impact of the atomized droplets entering the activation chamber 5, thereby avoiding the waste of heat in the cooling chamber 6 and increasing its utilization. In addition, during the activation reaction, gas will be generated. When the gas valve 11 is opened, the gas can carry heat through the gas delivery pipeline 10 and the connecting pipe 12 into the preheating chamber 2. The heat can promote the preheating treatment of the raw materials in the preheating chamber 2, reduce the pressure of the electric heating device, and further expand the effect of the heat. In addition, when in use, a processing pool 14 is set,The gases generated in the preheating treatment stage, carbonization treatment stage and activation treatment stage can be sent to the treatment pool 14 through the recovery pipe 13 and the short pipe. The corresponding solvents can be placed inside the treatment pool 14 according to the above-mentioned gas and other material components to absorb and treat the components in the above-mentioned products that cannot be reused. In addition, the gas that can be reused and burned can be sent to the boiler room for combustion through the output pipe 15 and the transfer pipe 16. In addition, the lower side of the treatment pool 14 is symmetrically provided with a circulation pipe to replace and replenish the solvent in the treatment pool 14. In addition, a motor 21 is provided, and the raw materials in the preheating chamber 2 can be stirred through the stirring rod 22, so that they are quickly and evenly heated to increase the preheating effect.
