[0002] VOC stands for volatile organic compounds. In the ordinary sense, VOC refers to volatile organic compounds; but in the environmental sense, it refers to a class of active volatile organic compounds, that is, the type of volatile organic compounds that can cause harm. VOC gases can be adsorbed and purified by activated carbon. Granular activated carbon is used in gas phase adsorption, usually by allowing the airflow to pass through the activated carbon layer for adsorption so that the gas meets emission standards.

[0003] However, the existing VOC activated carbon adsorption purification equipment places the activated carbon particles in the cavity of the adsorption tank body. Due to the stacking of the activated carbon particles, the laying is too thin, which affects the adsorption of VOC harmful gases. When a sufficient amount of activated carbon particles is laid, the gas resistance is large, which greatly reduces the gas circulation rate. A larger air pressure is required to provide power to allow the VOC gas to pass through the activated carbon particles for activated carbon adsorption, and the use effect is not good. Based on this, the utility model designs a VOC activated carbon adsorption purification equipment to solve the above problems. Utility Model Content
