Device and method for removing VOCs (volatile organic chemicals) by high-voltage pulse dielectric barrier discharge combined with electrostatic micro-jet atomization

Abstract

The invention discloses a device and a method for removing VOCs (volatile organic chemicals) by high-voltage pulse dielectric barrier discharge combined with electrostatic micro-jet atomization. The device comprises a high-voltage discharge chamber, a high-voltage pulse dielectric barrier discharge device, an alkaline atomization region and a system power draught fan, wherein the high-voltage pulse dielectric barrier discharge device comprises a high-voltage pulse electrostatic generator, a high-voltage electrode plate, an insulating dielectric body, a wire mesh and a grounding electrode; andthe alkaline atomization region comprises arrayed capillary atomization nozzles, a high-voltage electrostatic generator and an alkaline liquid supply box, and a liquid collecting box is arranged. A high-voltage discharge region is formed in the discharge chamber through the high-voltage pulse dielectric barrier discharge device, high-energy electrons, free hydroxyl groups, ozone and active ions are formed to fully oxidize and decompose gaseous molecules of the VOCs, and micron-sized alkaline atomized droplets absorb the organic exhaust gas to neutralize the acid gas. The device and the methoddisclosed by the invention can effectively kill bacteria in the air, absorb the organic gas and neutralize the oxidized and decomposed acid gas so as to realize removal of the VOCs in the chamber.

Description

technical field [0001] The invention relates to an indoor air purification device and a purification method, in particular to a device and method for removing VOCs by high-voltage pulse dielectric barrier discharge combined with electrostatic micro-jet atomization. Background technique [0002] At present, with the development of the economy and the improvement of people's material living standards, various organic polymers are widely used in daily life, such as interior decoration materials, electrical products, daily chemicals, etc., resulting in increasing indoor air pollution. Pollution has become an important environmental issue of public concern. Due to the relatively closed indoor environment, volatile organic compounds (Volatile Organic Compounds, referred to as VOCs) slowly released by various organic aggregate materials accumulate and release slowly indoors, which leads to an increase in the concentration of VOCs in the indoor air, and makes people living indoors s...
