[0032] By configuring a housing 1, an air inlet pipe 2, an air outlet pipe 3, an air inlet chamber 4, an adsorption chamber 5, a water storage chamber 6, an air outlet chamber 7, a first vent pipe 8, a second vent pipe 9, a water inlet pipe 10, a water outlet pipe 11, a water pump 12, a water extraction pipe 13, a water passage pipe 14, a water curtain paper 15, a mounting groove 16, a sealing plate 17, a sealing ring 18, a slider 19, and fixing bolts 20, the system achieves multi-stage adsorption of spray painting exhaust gas.

[0033] The air vent 7 is equipped with a replacement component, which includes an inlet / outlet slot 21 and a drawer 22. The inlet / outlet slot 21 is located on the rear wall of the housing 1. The drawer 22 is located inside the air vent 7 through the inlet / outlet slot 21. Limiting blocks 23 are fixedly installed on both sides of the drawer 22.

[0034] By setting up the inlet / outlet slot 21, the drawer 22, the limiting block 23, the cover 24, the lever 25, the seat 26, the limiting plate 27, and the fixing block 28, the function of quickly picking up and putting down activated carbon is realized. By realizing the rapid picking up and putting down of activated carbon, the purpose of conveniently replacing activated carbon is achieved, saving time and effort. On the basis of the original, the practicality of the adsorption equipment is further improved.

[0035] Working principle: Before using the adsorption equipment to adsorb and purify the spraying exhaust gas, water is added to the adsorption chamber 5 through the water inlet pipe 10. After the water enters the adsorption chamber 5, it wets the water curtain paper 15 and flows downward along the water curtain paper 15. Then it enters the water storage chamber 6 through the water leakage hole. At this time, the valve on the water outlet pipe 11 is closed. When the water in the water storage chamber 6 reaches a suitable water level, the water addition is stopped and the water pump 12 is turned on. When the water pump 12 is running, the water is drawn out from the water storage chamber 6 through the water pumping pipe 13 and introduced into the adsorption chamber 5 through the water passage pipe 14, so that the water flows downward on the water curtain paper 15, thereby forming a circulation.

[0036] When using an adsorption device to purify spray painting exhaust gas, the exhaust gas is introduced into the interior of the housing 1 through the inlet pipe 2. The exhaust gas then enters the interior of the inlet chamber 4 through the inlet pipe 2. Next, the exhaust gas enters the interior of the adsorption chamber 5 through the first vent pipe 8. The wetted water curtain paper 15 performs the first adsorption purification on the exhaust gas. Then, the exhaust gas spreads to the upper position of the outlet chamber 7 through the second vent pipe 9. The exhaust gas spreads downward from the top of the outlet chamber 7. During the spreading process, the activated carbon performs the second adsorption purification on the exhaust gas. After the two adsorption purification processes are completed, the exhaust gas is discharged from the interior of the outlet chamber 7 through the outlet pipe 3.

[0037] When the water curtain paper 15 needs to be replaced, tighten the fixing bolt 20 so that the fixing bolt 20 extends away from the sealing plate 17. After the fixing bolt 20 separates from the inner wall of the mounting groove 16, release the fixing of the sealing plate 17, and then pull the sealing plate 17 upward so that the sealing plate 17 slides upward inside the mounting groove 16. The slider 19 slides inside the groove. After the sealing plate 17 slides out from the inside of the mounting groove 16, release the restriction on the water curtain paper 15, and then take out the water curtain paper 15 from the inside of the adsorption chamber 5. Then take out the new water curtain paper 15 and reverse the above operation to put the new water curtain paper 15 into the inside of the adsorption chamber 5. The replacement of the water curtain paper 15 is completed. When the water source inside the water storage tank 6 becomes turbid due to adsorbing too much spraying exhaust gas, open the valve on the water outlet pipe 11 and discharge the water source from the water storage tank 6 through the water outlet pipe 11. After the discharge is completed, close the valve and then add water source again through the water inlet pipe 10.

[0038] When it is necessary to replace the activated carbon, rotate the limiting plate 27 upward so that the limiting plate 27 rotates out of the inside of the fixing block 28 and no longer abuts against the placement drawer 22. Then, pull the placement drawer 22 outward from the inside of the air outlet chamber 7 through the inlet / outlet groove 21. The limiting block 23 slides inside the limiting groove. After the placement drawer 22 slides out of the inside of the air outlet chamber 7, rotate the cover 24 upward. The cover 24 drives the card seat 26 to rotate upward, so that the card seat 26 separates from the card rod 25. After the cover 24 rotates out of the placement drawer 22, clean the old activated carbon out of the placement drawer 22 and put the new activated carbon into the placement drawer 22. Repeat the above operation in reverse to complete the replacement of activated carbon.
