[0028] It is also worth noting that the adsorption layer 14 in the present application can use activated carbon, an environmentally friendly material.

[0029] Preferably, the placement frame 12 is located on the top of the two limiting plates 11 , the placement frame 12 and the top of the adsorption layer 14 fit with the bottom of the fixed plate 9 , and the limiting block 19 can form an elastic structure with the mounting seat 16 through the spring 17 and the movable block 18 .

[0030] During specific use, the movable block 18 drives the limiting block 19 to retract by toggling the toggle block 20, and then the sealing plate 15 is pulled by the handle, so that the placement frame 12 can be pulled out from the inside of the box body 1. After being pulled out, the adsorption layer 14 inside the placement frame 12 can be replaced. After replacement, the placement frame 12 is reinserted into the box body 1. When the sealing plate 15 is in contact with the outer wall of the box body 1, the toggle block 20 is released. At this time, the limiting block 19 will pop out under the action of the spring 17 and the movable block 18, and the popped-out limiting block 19 will resist the sealing plate 15, so that the placement frame 12 cannot be pulled out, so that the adsorption layer 14 can be replaced more conveniently through the above method.

[0036] Working principle: VOC organic waste gas is introduced into the lower chamber of the box body 1 through the air inlet pipe 5. After the VOC organic waste gas is wet-washed by the microbial solution contained in the lower chamber, it enters the upper chamber from the first air outlet 8 of the partition 7 for treatment. The gas first enters the adsorption layer 14 from the through hole 13 and is absorbed, and then is discharged from the second air outlet 10 and the exhaust port 3 in turn. When the adsorption layer 14 needs to be replaced, the movable block 18 drives the limit block 19 to shrink by shifting the shift block 20, and then the sealing plate 15 is pulled by the handle, so that the placement frame 12 can be pulled out from the inside of the box body 1.
