[0058] Specific usage method and function of this embodiment:

[0059] When the present invention is in use, first, the staff connects the waste gas treatment housing 101 to the waste gas discharge pipe of the industrial furnace through bolts. The waste gas discharged from the industrial furnace first enters the two movable cooling pipes 501, ensuring that the high-temperature waste gas can be naturally cooled in the two movable cooling pipes 501, which plays a cooling role in the waste gas discharged from the industrial furnace and avoids the influence of the discharged high-temperature waste gas on the adsorption performance of the row of activated carbon cotton 202. When the lowermost activated carbon cotton 202 is saturated with adsorption, the resistance of the filtered waste gas passing through the lowermost activated carbon cotton 202 becomes larger, and the staff can judge the adsorption performance of the lowermost activated carbon cotton 202 by observing the outward movement distance of the two movable cooling pipes 501. The arrangement of the row of activated carbon cotton 202 plays a role in purifying and adsorbing the filtered waste gas. When the activated carbon cotton 202 needs to be replaced, the staff pulls out the lowermost purification housing 201. At this time, the upper purification unit 200 automatically slides downward. Then, the staff slides and installs the replaced purification housing 201 on the top of the uppermost purification housing 201, making the adsorption performance of the row of activated carbon cotton 202 gradually stronger from bottom to top, ensuring the purification effect of the waste gas, and also enabling the row of activated carbon cotton 202 to be fully utilized, avoiding the situation of insufficient utilization of the relatively thick activated carbon cotton 202. On the premise of ensuring the purification effect, the usage amount of the activated carbon cotton 202 is saved. The arrangement of the row of movable guide rods 302 plays a guiding role for the row of purification housings 201, enabling the row of purification housings 201 to only slide vertically. When the staff disassembles or installs the purification housing 201, the purification housing 201 can squeeze the corresponding movable guide rod 302 to move leftward. When the purification housing 201 is installed in place or disassembled, the corresponding movable guide rod 302 automatically resets to the right under the action of the return spring A 304. When the staff pulls the lowermost purification housing 201, the purification housing 201 can squeeze the circular movable rod 402 to move downward. When the circular movable rod 402 moves to another gas flow hole 2012, the circular movable rod 402 resets upward under the action of the return spring B 407, realizing the up-and-down reciprocating movement of the circular movable rod 402, which can automatically vibrate the impurities adhering to the ring of impurity filters 406, facilitating the dropping of the impurities on the ring of impurity filters 406. The setting of the movable seal frame 403 plays a sealing role for the ring of discharge slot holes A 1011, avoiding the discharge of untreated waste gas through the ring of discharge slot holes A 1011. When the purification housing 201 squeezes the circular movable rod 402 to move downward, the ring of discharge slot holes A 1011 is automatically aligned with the ring of discharge slot holes B 4031, realizing the automatic discharge of the impurities at the top of the conical seal cover 401, realizing the simultaneous cleaning of the activated carbon cotton 202 and the ring of impurity filters 406, and also automatically discharging the impurities after the previous cleaning.
