[0002] A large amount of waste gas is generated during industrial production. Direct emission of waste gas will cause serious harm to the environment and human body, which is not conducive to sustainable development. Based on this, my country has taken a variety of measures to deal with waste gas emissions, mainly to purify the waste gas generated in industrial production before discharging it. The existing waste gas purification methods generally use adsorption, condensation, combustion, photocatalysis and biological methods. As a treatment method that has emerged in recent years, the biological method is more environmentally friendly, but the efficiency is lower; the condensation method, combustion method and photocatalytic purification efficiency are high, but the cost investment is relatively high; the purification efficiency and cost investment of the adsorption method are moderate.

After passing through the closed space, the exhaust gas cannot be completely adsorbed and purified. It may take repeated cycles to make the exhaust gas emissions meet the standards. This is time-consuming and labor-intensive, and the purification efficiency is low. Utility Model Content

Based on this, the purification efficiency and purification effect of the exhaust gas are improved.

[0019] Specifically, if Figure 1 、 Figure 2 、 Figure 3As shown, several push-pull frames 8 are welded on the adsorption box 3, and the push-pull frames 8 are all in the cavity. The push-pull frame 8 is composed of two left and right opposite side surfaces and a bottom surface placed between the two side surfaces. A slide rail is provided on the bottom surface, and a push-pull cavity is formed between the two side surfaces and the bottom surface.
