A water outlet 103 is connected between one side below the filter plate 9 and the inside of the water tank 4, and an air outlet pipe 102 is provided at the top of the spray box 1.

[0022] The waste gas is sucked into the treatment box 2 through the air inlet pipe 3. At this time, the waste gas is filtered through the first activated carbon filter 12 and the second activated carbon filter 13 in turn. The filtered gas enters the spray box 1 through the air inlet 101, and then the medicine liquid is added into the water tank 4 through the water inlet 401. At this time, the water pump 5 is started to transport the medicine liquid through the delivery pipe 6 to the inside of the connecting pipe 7, and then the medicine liquid is sprayed through the spray head to spray the waste gas. The gas after spraying is discharged through the air outlet pipe 102, and the medicine liquid is filtered through the filter plate 9, and then flows into the inside of the water tank 4 from the water outlet 103, so that it can be recycled and reused.

[0023] A bottom plate 10 is provided at the bottom end of the interior of the treatment box 2, and side plates 11 are fixedly and symmetrically provided on the left and right sides of the upper end of the bottom plate 10, and the outer walls of the side plates 11 on both sides are in close contact with the inner wall of the treatment box 2 through sealing strips. The first activated carbon filter 12 and the second activated carbon filter 13 are respectively clamped between the two side plates 11, and the density of the first activated carbon filter 12 is greater than that of the second activated carbon filter 13. Since the density of the first activated carbon filter 12 is less than that of the second activated carbon filter 13, the first activated carbon filter 12 can filter larger impurities mixed in the exhaust gas, and the second activated carbon filter 13 can filter smaller impurities. A top plate 14 is fixedly provided at the top of the first activated carbon filter 12 and the second activated carbon filter 13, and a card slot matching the side plate 11 is opened at the bottom of the top plate 14, and a sealing strip is provided inside the card slot.

[0025] By pushing the rectangular push rods 15 on both sides of the processing box 2, the rectangular push rods 15 drive the limit plates 16 to compress the springs 17 to deform, so that one end of the rectangular push rods 15 moves toward the inside of the processing box 2. One end of the rectangular push rods 15 abuts against the inclined surface of the triangular block 18, thereby pushing the bottom plate 10 provided with the first activated carbon filter 12 and the second activated carbon filter 13 to move upward until the top plate 14 moves out of the top of the processing box 2. Then, the top plate 14 is removed, and the first activated carbon filter 12 and the second activated carbon filter 13 that need to be replaced are taken out from between the side plates 11 on both sides to facilitate replacement and installation of new ones.

[0026] When the exhaust gas treatment equipment is in use, the exhaust gas is sucked into the interior of the treatment box 2 through the air inlet pipe 3. At this time, the exhaust gas is filtered through the first activated carbon filter 12 and the second activated carbon filter 13 in turn. Since the density of the first activated carbon filter 12 is less than that of the second activated carbon filter 13, the first activated carbon filter 12 can filter out larger impurities mixed in the exhaust gas, and the second activated carbon filter 13 can filter out smaller impurities. The filtered gas enters the interior of the spray box 1 through the air inlet 101, and then the liquid medicine is put into the interior of the water tank 4 through the water inlet 401.
