Exhaust gas processor in coating production process

Abstract

The invention discloses an exhaust gas processor in a coating production process. The exhaust gas processor comprises an outer cylinder body and an inner gas guiding cylinder arranged in the center of the outer cylinder body; an air inlet pipe is arranged on tangential direction of the outer wall of the upper part of the outer cylinder body; the upper part of the outer cylinder body is in the shape of cylinder, and the lower part is a cone with gradually lessened diameter; the inner gas guiding cylinder is a cylinder with opened top part and bottom part; the upper part of the inner gas guiding cylinder extends out of the outer cylinder body by crossing through the top wall of the outer cylinder body; the lower part of the outer cylinder body is provided with a fluid collecting hopper connected with the bottom part of the outer cylinder body, and multiple layers of spraying pipes are arranged in the inner gas guiding cylinder; the spraying pipe is interconnected with the fluid collecting hopper through a circular pump; two layers of annular ceramic filtering plates loaded with a nanometer titania layer are arranged in the upper cavity between the inner gas guiding cylinder and the outer cylinder body; an annular ultraviolet light tubes are arranged between the annular ceramic filtering plates; the ultraviolet light tubes are connected with the inner wall of the outer cylinder body through two symmetrical supporting brackets. The exhaust gas processor combines cyclone separation, photo-catalytic oxidation, filtering and spraying into one; besides, the exhaust gas processor is small in floor area and good in purifying effect.

Description

technical field [0001] The invention relates to an exhaust gas processor in the paint production process. Background technique [0002] Because in the coating production process, the raw materials used contain a large amount of dust and gas components harmful to human health, such as small molecular substances such as aldehydes and benzene, if the waste gas is directly discharged into the air, causing air pollution, the current coating production enterprises Most of the waste gas treatment in production is carried out by direct emission and activated carbon adsorption. However, the existing activated carbon adsorption method has a weak adsorption capacity for these components and cannot effectively remove formaldehyde and other pollutants in the waste gas. Contents of the invention [0003] The invention provides a waste gas processor in the paint production process, which integrates cyclone separation, photocatalytic oxidation, filtration and spraying, occupies a small ar...
