Abstract

The invention relates to a car 4S stink waste gas purifying device. The car 4S stink waste gas purifying device comprises an adsorption unit and a plasma decomposition unit; the stink waste gas in a car 4S shop is purified by virtue of the filtering of a filter and the adsorption of a runner adsorption device to be discharged in the upper air; regenerative hot air formed by utilizing the electric heating is used for desorbing and regenerating the runner adsorption device, generated concentrated volatile organic matter air enters a plasma purifier to be decomposed and mineralized into carbon dioxide and water, and the waste heat of exhaust gas is recovered, so that the energy consumption is saved. An adsorption runner with a honeycomb structure is combined with the plasma purifier, so that the car 4S shop stink waste gas purifying device is very suitable for purifying the stink gas in the car 4S shop.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a device for purifying malodorous exhaust gas of an automobile 4S shop. Background technique [0002] In the automobile 4S shop, during the surface maintenance and spraying process of automobiles, foul-smelling gases containing volatile organic compounds such as toluene and benzene will be produced. These exhaust gases are difficult to treat, and most of them are directly discharged into the atmosphere, which seriously endangers the health of surrounding residents and must be strictly controlled. . At present, the malodorous exhaust gas of 4S stores is basically treated by activated carbon adsorption method, but the capacity of activated carbon is limited, and most enterprises cannot perform regular replacement or desorption regeneration. There is an urgent need for a stable technology and a good treatment effect to make the 4S waste gas discharge up to the standa...
