Electrode with waterfall type electric field

Abstract

The invention discloses an electrode with a waterfall type electric field. The electrode comprises two insulating plates which are oppositely arranged, two opposite negative electrode plates are fixed between the two insulating plates to form a gas channel with two through ends between the negative electrode plates and the insulating plates, at least one long and narrow positive electrode sheet is arranged between the two insulating plates, the at least one long and narrow positive electrode sheet is perpendicular to the negative electrode plates, and equal spaces are left between the corresponding edge of the at least one long and narrow positive electrode sheet and the inner sides of the negative plates. The negative electrode plates, the long and narrow insulating plates and the at least one long and narrow positive electrode sheet form the electrode assembly having a gas flow channel, and the two long edges of the at least one positive electrode sheet discharge electricity to two sides during practical use in order to form the waterfall type electric field between the positive electrode sheet and the positive electrode plates, so the electric field intensity is high, and the gas treatment effect is good. The mounting structures of the positive and negative electrodes are simple, and the interaction edges and the plate surfaces of the positive and negative electrodes are smooth without welds, so the installation coaxiality problem of the cylindrical electrode and the spike voltage problem of welds are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of gas purification equipment, and in particular relates to an electrode assembly of an electric field in the gas purification equipment. Background technique [0002] At present, with the advancement of society and technology, people's awareness of safety and environmental protection has been improved, and people's requirements for air quality have become higher and higher, and various industrial or civil gas purification equipment have emerged as the times require. Existing low-temperature plasma gas purification equipment often uses a cylindrical or ring-shaped structure to form one of the electrodes, and the other electrode is formed in a needle-shaped, disc-shaped or linear form, which mainly has the following shortcomings: [0003] 1. The electric field strength is weak, the gas cannot be fully treated, the treatment effect is poor, and the efficiency is low; [0004] 2. Cylindrical electrodes have hi...

AI Technical Summary

Problems solved by technology

[0003] 1. The electric field strength is weak, the gas cannot be fully treated, the treatment effect is poor, and the efficiency is low;

[0004] 2. Cylindrical electrodes have high material costs. If seamless steel pipes are used, the weight of the electrodes is large, which is not conducive to the overall weight control of the equipment; if welded pipes are used, the welds on the pipes are likely to form peak voltages; The welding workload between the end of the cylinder and the corresponding end plate is heavy, and the welding operation is troublesome;

[0005] 3. The assembly operation between the cylindrical electrode and the other electrode in the cylinder is troublesome, and it is not easy to ensure the coaxiality
