Reactor for treating VOCs (Volatile Organic Chemicals) synergistically under catalysis of plasma

Abstract

The invention discloses a reactor for treating VOCs (Volatile Organic Chemicals) synergistically under catalysis of plasma. The reactor comprises a shell, wherein one side of the shell is provided with an air inlet; the other side of the shell is provided with an air outlet; the air inlet and the air outlet are arranged correspondingly; an upper part of the shell is provided with an insulator chamber; an air inlet channel is formed in the shell; the air inlet channel comprises two positive plates which are arranged vertically in parallel; a plurality of negative rods which are parallel are arranged vertically in the air inlet channel; upper ends of the negative rods are fixed in the insulator chamber; an air outlet channel is constructed by the positive plates and an inner wall of the shell; each positive plate comprises two mesh plates which are arranged in parallel; a catalyst is placed in a space between the two mesh plates. The insulator chamber is arranged on the upper part of the shell, so that a creepage distance can be prolonged, dirt such as floating dust is prevented from adhering to the surface of an insulator, and a formed path is broken down by voltages at two ends of the insulator; moreover, low-temperature plasma is generated by wire-plate corona discharging, so that the number of discharging space electrons or active free radicals and the distribution uniformity are increased and improved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to a reactor for plasma cooperative catalytic treatment of VOCs. Background technique [0002] With the intensification of air pollution, how to effectively deal with air pollutants is an extremely important issue, among which volatile organic compounds (VOCs, which is the English abbreviation of volatile organic compounds) are a kind of pollutants with relatively serious pollution. [0003] At present, the way to deal with VOCs is mainly to remove them through plasma co-catalysts. The main way to generate plasma is through gas discharge, which mainly includes: glow discharge, radio frequency discharge, corona discharge and dielectric barrier discharge. [0004] Among them, during the glow discharge process, the electrodes and the reaction space are in a low-pressure state, which belongs to low-pressure discharge. Due to the low pressure of the working gas, the require...
