The end of the inlet pipe 5 away from the water pump 4 is connected to the connecting pipe 6. Several spray heads 7 are fixedly connected at equal intervals at the bottom end of the connecting pipe 6.

[0024] Electroplating waste gas enters the interior of the treatment cylinder 1 through the air inlet 101. Then, the water pump 4 is started to pump the liquid inside the storage tank 2 through the liquid inlet pipe 5 to the connecting pipe 6, and sprays the waste gas through the spray head 7 for purification. After being filtered by the filter screen 14, the sprayed water falls into the bottom of the treatment cylinder 1 and is finally discharged through the drain outlet 103. Then, the waste gas after being sprayed is purified by the adsorption of the activated carbon adsorption layer 15 and is discharged from the exhaust outlet 102.

[0025] Both sides of the front end of the two fixed frames 8 are provided with movable grooves 801. Connecting rods 9 are fixedly connected inside the movable grooves 801 on both sides. Sliding plates 10 are slidably connected to the outer surfaces of the two connecting rods 9. Limiting plates 12 that extend through the movable grooves 801 and reach the outside of the fixed frames 8 are fixedly connected to the side of the two sliding plates 10 that is away from each other. A spring 11 is fixedly connected between the side of the sliding plate 10 away from the limiting plate 12 and the inner wall of the movable groove 801. The spring 11 is wrapped around the outer surface of the connecting rods 9. A sealing gasket 19 is fixedly connected to the upper end of the fixed frame 8. The connecting frame 13 is U-shaped and snapped onto the upper outer surface of the fixed frame 8. The bottom end of the connecting frame 13 contacts the sealing gasket 19.

When it is necessary to replace or clean it, by pushing one end of the limiting rod 18 inside the limiting hole 10201, the limiting rod 18 is tilted outward and retracted into the interior of the groove 1601. Then the mounting tube 16 can be taken out from the interior of the exhaust port 102, thereby allowing the filter cartridge 17 to be disassembled.

[0029] When the electroplating waste gas treatment device is in use, the electroplating waste gas enters the interior of the treatment cylinder 1 through the air inlet 101. Then, the water pump 4 is started to pump the liquid inside the storage tank 2 through the liquid inlet pipe 5 to the connecting pipe 6, and sprays the waste gas through the spray head 7 for purification. After being filtered by the filter screen 14, the sprayed water falls into the bottom of the treatment cylinder 1 and is finally discharged through the drain outlet 103. Then, the waste gas after being sprayed is purified by the adsorption of the activated carbon adsorption layer 15 and is discharged from the exhaust outlet 102.

[0030] After the filter screen 14 and activated carbon adsorption layer 15 have been used for a long time, by pinching the sliding plates 10 on both sides of the front end of the fixed frame 8, the sliding plates 10 on both sides slide along the outer surface of the connecting rod 9 towards each other, and compress the spring 11, thereby driving the limiting plate 12 to move into the interior of the movable groove 801, disengaging from the locking with the limiting groove 1301, and then the connecting frame 13 can be removed, making it easy to disassemble the connecting frame 13 and clean or replace the filter screen 14 and activated carbon adsorption layer 15 inside it.

[0031] The filter cartridge 17 installed at the top of the exhaust port 102 can prevent external dust and impurities from entering the interior of the processing cartridge 1 through the exhaust port 102. When it is necessary to replace or clean it, by pushing one end of the limiting rod 18 inside the limiting hole 10201, the limiting rod 18 is tilted outward and retracted into the interior of the groove 1601. Then the mounting tube 16 can be taken out from the interior of the exhaust port 102, thereby allowing the filter cartridge 17 to be disassembled.
