The air outlet enters the inlet of the desorption fan 19, and the medium-temperature fresh air enters the heater 18 from the outlet of the desorption fan 19 and becomes hot air. The hot air is passed into the activated carbon adsorption box 16 through the valve 4 8 for desorption, and the temperature is monitored by the temperature sensor 2 7. When the temperature reaches 100 ° C, the heater 18 starts to heat, and the hot air takes away the pollutants, and passes through the valve 5 15 in turn. and the high temperature exhaust gas inlet into the heat exchanger 1, part of the heat of the high temperature exhaust gas is absorbed by the heat exchanger 1, realizing the recycling of the hot air, the exhaust gas enters the horizontal scrubber 2 through the medium temperature exhaust gas outlet and the valve 11 in turn, and part of the exhaust gas enters the horizontal scrubber 2. After the pollutants are absorbed by the horizontal scrubber 2, they enter the photocatalytic oxidation device 6 through valve 74. When the photocatalytic oxidation material is irradiated by ultraviolet light with energy greater than the forbidden band width, the electrons transition from the valence band to the conduction band, resulting in a Electron-hole pairs, electrons are reducible, holes are oxidizing, holes react with -OH on the surface of oxide semiconductor nanoparticles to generate highly oxidizing OH radicals, active OH radicals can oxidize organic waste gas For inorganic substances such as CO2 and H2O, the clean gas is discharged into the atmosphere through the exhaust pipe 10.
