then after the catalyst plate 703 is used for a period of time, the rotating handle 704 is pulled outwards to enable the pushing plate 701 to slide through the guide rail block 6, so that the rotating plate 702 can be separated from the outer wall of the catalytic combustion box 1, the catalyst plate 703 is moved out of the catalytic combustion box 1, at this time, the rotating handle 704 is rotated to enable the rotating plate 702 to rotate at the top of the pushing plate 701, so that the catalyst plates 703 on the front and back sides of the rotating plate 702 can be reversed, at this time, the rotating handle 704 is pushed to enable the other catalyst plate 703 to move into the catalytic combustion box 1, during the catalytic combustion process, the catalyst plates 703 are prone to be broken and worn due to the effects of factors such as long-time high temperature and air flow, and the purification effect is affected, and by rapidly reversing and cooling the two catalyst plates 703 in a clearance way, the working time of the single catalyst plate 703 can be reduced without affecting the normal operation of the equipment, this can effectively increase the service life of the catalyst plate 703;

after catalytic combustion of the waste gas is completed, the waste gas can be conveyed to the inside of the heat exchange chamber 12 through the vent pipe 10 by the exhaust fan 11, cold water can be conveyed to the inside of the heat exchange pipe 14 through the water inlet pipe 13, the waste gas can exchange heat with the cold water in the heat exchange pipe 14 after entering the inside of the heat exchange chamber 12, the temperature of the waste gas can be reduced, the waste gas can be prevented from burning parts in equipment, the temperature of the cold water after heat exchange can be increased, the cold water can enter the inner side of the heating box 22 through the water through pipe 15, the energy for heating the water to the boiling point by the heater 23 in the heating box 22 can be reduced due to the fact that the water is preheated through heat exchange, and after the water is heated to the boiling point by the heating box 22, hot water can be conveyed out of the equipment through the water outlet pipe on the outer side for processing and use by a factory;

the waste gas after heat exchange can enter the activated carbon adsorption tube 16 and contact with the activated carbon layer 17, the activated carbon layer 17 can absorb harmful substances remaining in the waste gas after contacting with the waste gas, and the purified air can be discharged out of the equipment through the exhaust port 21, during the air discharge process, the sulfide detector 19 can detect sulfides in the air, if the detection is not qualified, the second valve 20 is closed, the water vapor generated by heating of the heating box 22 can enter the inner side of the annular tube 2402 through the steam tube 2401 and be sprayed out by the steam spraying seat 2403, the water vapor contacts with the activated carbon layer 17 and floats upwards and passes through the activated carbon layer 17, the absorption box 2501 can work to generate suction force, so that the water vapor passing through the activated carbon layer 17 can be sucked into the absorption box 2501 through the air suction port 2503 and the air suction pipe 2502, and the water vapor can be prevented from floating to the surfaces of the flow rate detector 18 and the sulfide detector 19, the detection precision of the two is influenced;

finally, the steam desorption component 24 works, after the high-temperature steam is sprayed to the activated carbon layer 17, the sprayed steam can desorb the impurities adsorbed by the activated carbon layer 17, thereby the activated carbon layer 17 can be regenerated, the sulfide detectors 19 are provided with two detectors, the detection precision can be improved by the common detection of the two sulfide detectors 19, in addition, after the activated carbon layer 17 is adsorbed for a long time, the internal space gap can be reduced, this causes the flow rate of air passing through the activated carbon layer 17 to be reduced, detected by the flow rate detector 18, the second valve 20 may be closed after the air flow rate is lower than a certain level, so that the vapor desorption assembly 24 operates to desorb the activated carbon layer 17, by the double detection of the flow rate detector 18 and the sulfide detector 19, it is possible to make a good judgment as to whether the regeneration of the activated carbon layer 17 is completed, thereby, it is possible to avoid the occurrence of a situation in which the desulfurization effect is poor due to the desulfurization of the activated carbon layer 17 that has not been regenerated.
