[0002] Volatile organic compounds, commonly referred to as VOCs, are usually adsorbed and purified with activated carbon fibers before being discharged into the atmosphere in order to effectively purify organic waste gas. As an excellent physical and chemical adsorbent, activated carbon is increasingly valued by people. Working principle of activated carbon adsorption: waste gas containing organic matter passes through the activated carbon adsorption layer under the action of the fan. The organic matter is adsorbed in the activated carbon micropores by the characteristics of activated carbon's multiple micropores, large specific surface area, and strong adsorption capacity, and the clean gas is discharged; after a period of time, when the activated carbon reaches a saturated state, the adsorption stops, and the organic matter has been concentrated in the activated carbon. The saturated activated carbon is then desorbed and regenerated using catalytic combustion hot air and put back into use.

[0003] A new type of VOCs treatment equipment with application number CN202020711398.0 in the prior art can slow down the flow of gas, make the adsorption effect better, and make the clean gas be discharged. The curved channel formed by the corrugated plate slows down the flow of gas. However, when the adsorption filter layer of the treatment equipment is blocked or needs to be replaced and repaired, it needs to be shut down for a long time, which affects the efficiency of treatment and is inconvenient to clean and repair the attached filter layer.
