[0002] Dioxin is a colorless and odorless, highly toxic substance containing many isomers or isomers. This kind of substance is very stable, has a high melting point, is difficult to dissolve in water, can be dissolved in most organic solvents, is easy to accumulate in the human and animal body, has strong carcinogenicity, teratogenicity and mutagenicity, and often exists in the flue gas generated after waste incineration.

[0045] The use method of the embodiment is: in the case that the user actually processes dioxin in the flue gas generated after garbage incineration, first start the water pump 57, the water pump 57 passes through the water inlet pipe 56 to pass the cold water stored in the water tank 58 into the water flow channel 53, then the flue gas after incineration is passed into the cooling cylinder 51 from the air inlet pipe 52, the heat in the flue gas is transmitted to the cold water by the copper metal material cooling cylinder 51, the cold water and the flue gas form heat exchange, the flue gas is cooled, the cold water is heated, then the flue gas enters the guide gas channel 32 from the first air pipe 33, enters the four movable cylinders 6 from the guide gas channel 32, the flue gas flows downward from the activated carbon gap filled in the movable cylinder 6, fully contacts with the activated carbon, the activated carbon processes the dioxin in the flue gas for the first level, adsorbs part of the dioxin in the flue gas, the adsorbed flue gas enters the activated carbon adsorption box 3 from the hollow net 65 at the bottom of the movable cylinder 6, then enters the annular pipe 21 from the second air pipe 23, the flue gas in the annular pipe 21 enters the organic solvent from the air outlet hole 22, the flue gas fully contacts with the organic solvent in the process of floating in the organic solvent, the organic solvent processes the dioxin in the flue gas for the second level, dissolves part of the dioxin, the upward floating flue gas enters the hollow groove 17 from the third air pipe 25, is divided into two parts from the air outlet 18, then enters the high-voltage pulse purification box 1, the high-concentration charged ions are formed in the high-voltage pulse purification box 1 by the discharge electrode 11, collide with each other in the electric field, processes the dioxin in the flue gas for the third level, makes the dioxin directly ionize to form hydrogen radical, hydroxyl radical and free radical, the particle fly ash in the flue gas adheres to the surface of the discharge electrode 11, falls to the bottom of the high-voltage pulse purification box 1 after long-time accumulation, the flue gas after the third level processing is finally discharged from the air outlet pipe 13.When the activated carbon in the activated carbon adsorption box 3 is used for a long time and the pores are blocked, the rotating shaft 66 is driven to rotate by the motor 34, the rotating shaft 66 drives the partition plate 61 to rotate, the partition plate 61 drives the movable cylinder 6 to rotate 180° in the through slot 31, the movable cylinder 6 drives the two side insertion blocks 64 to move, the through slot 31 makes the inner wall of the through slot 31 extrude the inclined edge of the insertion block 64, so that the insertion block 64 is retracted into the sliding groove 62, and the spring 63 is compressed. When the insertion block 64 is opposite to the insertion slot 310 after the movable cylinder 6 rotates 180°, the spring 63 rebounds to push the insertion block 64 into the insertion slot 310, and the movable cylinder 6 is positioned by the insertion block 64 and the insertion slot 310. The positions of the two adsorption cavities are exchanged, the activated carbon with blocked pores is transferred from the activated carbon adsorption box 3 to the high-temperature steam reduction box 4, and the activated carbon transferred from the high-temperature steam reduction box 4 to the activated carbon adsorption box 3 continues to be used for dioxin adsorption. At the same time, the insertion block 64 extrudes the pressure sensor 311 in the insertion slot 310, the pressure sensor 311 detects the extrusion pressure and transmits a signal to the control box 7, the control box 7 controls the air pump 39 to start, the air pump 39 fills air into the air branch pipe 37 through the air main pipe 38, the air flow enters the sealed air bag 36 to make it expand, and the sealed air bag 36 tightly adheres to the outer side wall of the movable cylinder 6 to seal the gap between the movable cylinder 6 and the through slot 31. Then the internal pure water is heated by the annular heating assembly 41 to make the water boil and generate high-temperature steam, the high-temperature steam passes through the annular plate 43 and the hollow net 65 to fully contact with the activated carbon, the high-temperature steam heats the activated carbon to carbonize or desorb the impurities adsorbed in the activated carbon, so that the activated carbon restores its original activity. When the liquid level sensor 42 detects that the water level in the high-temperature steam reduction box 4 is low, the water outlet valve 510 is opened, and the water carrying flue gas heat in the water flow channel 53 enters the high-temperature steam reduction box 4 from the water outlet pipe 59, so that the heat in the flue gas is used for generating high-temperature steam, and the energy consumption of the annular heating assembly 41 is reduced.
