Abstract

The invention discloses a dielectric barrier discharge based organic waste gas purifying device. Dielectric barrier tubes (7) are externally wrapped by metal net high-voltage electrodes (4) and internally filled with conductive filler (3), and low-voltage electrodes (2) are mounted at centers of the dielectric barrier tubes (7). A frame support is formed by combination of an external frame box (6)and an internal frame mounted in the external frame box (6). The internal frame is formed by a lower frame box (5) and an upper metal sealed box. An upper plate and a lower plate of the lower frame box are provided with a plurality of rows of staggered through holes, and dielectric barrier dischargers are mounted in the upper and lower layers of through holes. The device has advantages of compactness, small floor area, convenience in manufacturing, mounting, utilization and maintenance, long service lives of the dielectric barrier tubes and can be widely applied to the industry of gas pollution treatment in coating, furniture paint spraying, paint and printing ink production, printing and the like.

Description

technical field [0001] The invention relates to a plasma discharge device for purifying organic waste gas, which is mainly used in gaseous pollution control industries such as painting, furniture painting, paint ink production and printing industry, and can also be used for purification and treatment of industrial organic waste gas. Background technique [0002] Dielectric barrier discharge (DBD) is a kind of low-temperature (non-equilibrium) plasma obtained by the breakdown of air by high-voltage electricity under normal pressure conditions. At present, this technology is mainly used in the fields of ozone synthesis, vacuum ultraviolet light source, material surface treatment and environmental protection. In recent years, with the increasing awareness of environmental protection in my country and the limitations of existing treatment methods, dielectric barrier discharge technology has penetrated into various fields of gaseous pollution control. Such as volatile organic co...
