Electrode slice, electrode plate, electrode block and plasma generator

Abstract

The invention relates to the technical field of plasmas, and discloses an electrode slice, an electrode plate, an electrode block and a plasma generator. The electrode plate (115) comprises a blockingdielectric plate (1151), an insulating seat (1154) with a mounting groove, a conductive connecting piece (1153) and a conducting strip (1156) arranged between the blocking dielectric plate and the insulating seat. The conducting strip and the insulating seat are positioned in the mounting groove, one end of the conductive connecting piece is connected to the conducting strip, and the other end ofthe conductive connecting piece extends to the outside of the insulating seat to form an electric connecting terminal (1155), wherein an insulating glue (1152) is filled in the gaps between the blocking dielectric plate and the mounting groove and between the conductive sheet and the mounting groove. The electrode slice is simple in structure, can effectively and stably seal and insulate the conducting strip for a long time, and is convenient for the simple installation and rapid disassembly of the plate-type electrode.

Description

technical field [0001] The invention relates to the field of plasma technology, in particular to an electrode sheet, an electrode plate, an electrode block and a plasma generator. Background technique [0002] Low-temperature plasma technology is a cost-effective way to treat waste gas, which can be used to treat a variety of gas-phase pollutants, such as volatile organic compounds (VOCs), nitrogen oxides (NOx) and sulfur dioxide (SO 2 )Wait. There are various forms of plasma generators, including corona discharge, dielectric barrier discharge and sliding arc discharge, among which dielectric barrier discharge is the most widely used plasma generator. The dielectric barrier discharge plasma generator separates the two discharge electrodes (high voltage electrode and ground electrode) through an insulating medium, which reduces the generation of spark discharge and improves the stability of the discharge process. Furthermore, the double-dielectric barrier discharge plasma g...

Problems solved by technology

The advantages of the tube-type electrode are simple structure, convenient maintenance, and low manufacturing cost. The disadvantage is that the discharge area is small, which is only a thin-layer area formed by two adjacent high-voltage electrodes and ground electrodes on the closest curved surface.

Relatively speaking, the large discharge area of ​​the row-plate electrode makes it have higher pollutant degradation performance, but the disadvantage is that the structure is complex, and the electrodes are usually packaged in insulating materials (such as ceramic glue, glass glue, etc.) Ceramics, etc.) The internal packaging method is not tolerant to industrial waste gas with complex components, which can easily cause small cracks in the bonding area, which will lead to creepage
