Adsorption device is one of the common waste gas treatment technologies, especially in the occasions where the concentration of organic matter in the air is low or organic pollutants need to be removed efficiently. By using adsorption materials to adsorb organic chemicals in the waste gas, when the waste gas flows through the adsorbent, the organic matter molecules interact with the adsorbent surface, and the adsorbent adsorbs these organic substances to its surface or internal pores, thereby achieving the effect of purifying the air.

[0041] Embodiment 3

[0042] In conjunction with Example 1 and Example 2, please refer to Figure 1 as well as Figures 5 to 7 As shown, the specific improvements are as follows: the clamping assembly includes a fixing block 15 fixed on the surface of the adsorption box 1, one side of the inner wall of the fixing block 15 is fixedly connected with a spring 16, and one end of the spring 16 is fixedly connected with a clamping rod 17, one end of the clamping rod 17 penetrates the outside of the fixing block 15, and one side of the sealing plate 5 is provided with a through hole 18 adapted to the clamping rod 17, and the surface of the clamping rod 17 and located outside the fixing block 15 is fixedly connected with a handle 19, and the handle 19 is convenient for driving the clamping rod 17 to move;

[0043] One side of the frame 62 is connected to the upper filter plate 61 through four fixing mechanisms 22, and the other side of the frame 62 is fixedly connected to one side of the lower filter plate 63. The inner wall of the frame 62 is fixedly connected with a partition frame 23, and the partition frame 23 divides the interior of the frame 62 into a plurality of placement grids, which are used to evenly distribute the activated carbon particles in the frame 62 to improve the adsorption efficiency. The fixing mechanism 22 includes a screw 221 fixed to the surface of the frame 62, and one end of the screw 221 passes through the outside of the upper filter plate 61 and is threadedly connected with a hand nut 222.

[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0046] When in use, the organic waste gas enters the adsorption box 1 through the air intake pipe, and the water in the water tank 14 is extracted by starting the water pump 2, and then the water is evenly sprayed in the adsorption box 1 through the water outlet pipe 3 and the spray plate 4, so as to fully contact with the incoming waste gas.

[0047] After the exhaust gas is pre-treated, it is adsorbed and purified by two activated carbon adsorption plates 6 and molecular sieve 21 in turn, which has a better effect. At the same time, the handle 19 drives the clamping rod 17 to squeeze the spring 16, and moves out the through hole 18 on the side of the sealing plate 5, so that the sealing plate 5 is separated from the adsorption box 1. Then the two activated carbon adsorption plates 6 and the molecular sieve 21 can be directly pulled out of the adsorption box 1, which is convenient for cleaning or replacement. By screwing the hand nut 222 out of the screw 221 and taking out the anti-loosening gasket 223, the upper filter plate 61 can be removed, and the internal activated carbon particles can be quickly replaced, and the activated carbon particles are evenly distributed on the isomorphic partition frame 23.
