The invention discloses a VOCs collecting and treating device. The VOCs collecting and treating device comprises a VOCs catcher, wherein the VOCs catcher comprises a main
machine frame, an auxiliary
machine frame, an outer adsorption layer formed by a circle of a plurality of
activated carbon plates, and an inner adsorption layer formed by a circle of the plurality of
activated carbon plates, theinner adsorption layer is surrounded by the outer adsorption layer, the outer adsorption layer is fixed on the main
machine frame, and the inner adsorption layer is fixed on the auxiliary machine frame, the auxiliary machine frame is fixedly connected with the main machine frame, a closed
photocatalysis chamber is formed between the inner adsorption layer and the outer adsorption layer, a plurality of
ultraviolet lamps are uniformly distributed in the
photocatalysis chamber, a circulation cavity is formed in the middle of the inner adsorption layer, the upper end of the main machine frame is provided with an exhaust port communicated with the circulation cavity, a blower is fixedly arranged in the exhaust port, a negative pressure is formed in the circulation cavity through the blower, theouter side of the outer adsorption layer is covered by a filter screen, the filter screen is fixed on the main machine frame. The VOCs collecting and treating device has the advantages of high efficiency, easy installation, multi-function and integration, and low cost and the like.
