Louver type large-area cold plasma exhaust gas processing device

Abstract

The invention discloses a louver type large-area cold plasma exhaust gas processing device which comprises a plasma shell, a plurality of plasma generators are arranged in at least one cross section of an inner cavity of the shell, the plasma generators on a same cross section are connected along the outer edges thereof and fill the cross section, the plasma generators are perpendicular to an air inlet of the shell, each plasma generator comprises an insulating base, the front and rear surfaces of the base are respectively connected with an airflow equispaced grid, a plurality of insulating medium tubes are vertically connected between left and right plates of the inner cavity of the base from top to bottom, one ends of the insulating medium tubes are closed, the insulating medium tubes are all arranged in a same cross section of the base, the closed ends of adjacent insulating medium tubes are arranged in a left-right alternate arrangement mode, an electrode is in close fit with the inside of each insulating medium tube, one end of each electrode is connected with an electrode wire, and the electrode wires on the left and right sides of the base are respectively connected with the high voltage end and ground end of a high-voltage alternating current power supply. The louver type large-area cold plasma exhaust gas processing device disclosed by the invention can obtain a high gas processing flow rate, and can maintain high-density large-area plasmas, so that the electric discharge is in a stable state, thereby improving the treatment efficiency and reducing the energy consumption.

Description

technical field [0001] The invention relates to a waste gas purification device, in particular to a shutter-type large-area cold plasma waste gas treatment device. Background technique [0002] With the development of the economy, the toxic and harmful gaseous pollution (such as H 2 S, SO 2 , NOx, VOCs, etc.) problems are becoming increasingly serious. [0003] Low-temperature plasma technology is a hot technology in the field of gaseous pollutant control in recent years. Plasma technology has the characteristics of short treatment process, high efficiency, low energy consumption, less secondary pollution, and wide application range. It is considered to be a promising deep purification technology for environmental pollution. Plasma is a mixed state of electrons, positive and negative ions, excited atoms, atoms, and free radicals. The state of plasma mainly depends on physical and chemical parameters such as its chemical composition, particle density and particle temperat...

Problems solved by technology

Especially for the coaxial discharger, it is necessary to increase the outer diameter of the outer electrode. Due to the increase of the curvature of the outer electrode and the increase of the electrode spacing, the breakdown voltage increases. Even if the double dielectric is changed to a single dielectric, the discharge may in an unstable state
