[0002] Microwave desorption of activated carbon is a new desorption technology developed based on the principle of temperature rise desorption. In temperature rise desorption, the adsorbed components can be desorbed by increasing the temperature of the adsorbent, and the temperature in the whole process changes periodically. As an improvement of temperature rise desorption, microwave desorption technology uses microwave radiation to heat activated carbon, which can increase the temperature of activated carbon more quickly and evenly, and accelerate the desorption process of the adsorbate.

The bottom end of the second ventilation pipe 406 is installed with a waste gas treatment device 407. The air intake holes 402 are arranged at equal intervals on the outside of the waste gas collecting cylinder 401. The horizontal center axis of the waste gas collecting cylinder 401 is symmetrical to the horizontal center axis of the activated carbon desorption treatment tank 3. Overlapping arrangement; the inner cavity of the activated carbon desorption treatment tank 3 forms a connecting structure with the inner cavity of the exhaust gas collecting cylinder 401 through the air inlet hole 402, and the exhaust gas collecting cylinder 401 forms a connecting structure with the exhaust gas treatment equipment 407 through the gas collecting pipe mouth 403, the first ventilation pipe 404, the first rotating joint 405, and the second ventilation pipe 406. The first ventilation pipe 404 forms a rotating structure with the second ventilation pipe 406 through the first rotating joint 405; the outer part of the activated carbon desorption treatment tank 3 is a sealed structure, and the exhaust gas generated by the activated carbon during the desorption process cannot be emitted to the outside, and can only enter the interior of the air inlet hole 402 through the exhaust gas collecting cylinder 401, and be transported to the interior of the exhaust gas treatment equipment 407 for treatment, and then discharged after treatment, so as to effectively prevent it from polluting the air environment.

[0026] like Figure 3As shown, the treatment tank transmission component 5 is used to drive the treatment tank to rotate so that the activated carbon at various positions inside the treatment tank can receive microwave treatment; the treatment tank transmission component 5 includes a servo motor 501, the output end of the servo motor 501 is fixedly connected to a linkage shaft 502, the other end of the linkage shaft 502 is fixedly connected to a support block 503, the outside of the linkage shaft 502 is fixedly connected to a transmission gear 504, the outside of the transmission gear 504 is meshed with a transmission sawtooth ring 505, and the servo motor 501 is connected to the transmission sawtooth ring 505 through the linkage shaft 502 and the transmission gear 504.

[0028] Working principle: first, the activated carbon that needs to be desorbed after adsorption saturation is added into the activated carbon desorption treatment tank 3 through the activated carbon discharge port 7. After it is full, the activated carbon discharge port 7 is closed, and then the microwave generator 2, the steam generating device 601, the exhaust gas treatment device 407 and the servo motor 501 are started. The microwave generator 2 emits microwaves to treat the activated carbon inside the activated carbon desorption treatment tank 3. Microwave desorption uses a high-frequency electric field to excite the water molecules or organic molecules loaded in the activated carbon to desorb them. At the same time, the output end of the servo motor 501 rotates with the transmission gear 504 through the linkage shaft 502. Since the transmission gear 504 and the transmission sawtooth ring 505 are meshed with each other, when the transmission gear 504 rotates, the transmission gear 504 will rotate with the activated carbon desorption treatment tank 3 through the transmission sawtooth ring 505, so that different surfaces of the activated carbon desorption treatment tank 3 have the opportunity to face the microwave generator 2 below;

[0029] At the same time, the steam generated inside the steam generating device 601 is transported to the inside of the activated carbon desorption treatment tank 3 through the steam transport main pipe 602, the second rotary joint 603, the steam diversion pipe 604, and the steam transport branch pipe 605. The activated carbon inside the activated carbon desorption treatment tank 3 is desorbed by the microwave and the waste gas will enter the waste gas collecting cylinder 401 through the air inlet hole 402, and then enter the waste gas treatment equipment 407 through the gas collecting pipe mouth 403, the first ventilation pipe 404, the first rotary joint 405, and the second ventilation pipe 406 in turn for treatment.
