A device and method for degrading sulfur hexafluoride based on sliding arc discharge

Abstract

The invention discloses a sulfur hexafluoride degradation treatment device and treatment method based on sliding arc discharge, which includes a spiral electrode spray gun connected to a host computer through a cable at its tail; the cable contains a high-voltage line, a grounding line and an air intake pipe of the spray gun , used to provide high-frequency voltage and sulfur hexafluoride gas to the reactor in the spiral electrode spray gun; high-frequency discharge occurs between the high-voltage electrode and the ground electrode in the spiral electrode spray gun, and dense plasma is generated in the discharge area The sulfur hexafluoride gas collides with the plasma in the discharge area and is ionized and decomposed; the front end of the spiral electrode spray gun is connected with a quartz tube, and the other end of the quartz tube is connected with an alkali liquid absorption pool, which is used to decompose sulfur hexafluoride The toxic acid gas in the decomposition tail gas is absorbed. The invention can solve the technical problems of only recovering the sulfur hexafluoride gas without degrading or degrading the sulfur hexafluoride gas at the present stage with low treatment capacity, low degradation rate, and no tail gas collection device.

Description

technical field [0001] The invention relates to the technical field of sulfur hexafluoride degradation, in particular to a device for degrading sulfur hexafluoride based on sliding arc discharge, and also relates to a method for degrading sulfur hexafluoride based on sliding arc discharge. Background technique [0002] Sulfur Hexafluoride (SF 6 ) gas is an inert gas at normal temperature and normal state. Its physical and chemical properties are stable, colorless, odorless, non-toxic, non-corrosive, slightly soluble in water, non-flammable, and its density is about 5 times that of air. SF 6 Is a non-polar, very strong electronegativity molecule, its electrical insulation performance under normal pressure is that of air, N 2 2.5 times that of air, and the arc extinguishing performance is about 100 times that of air, so SF 6 It has become a widely used insulating medium. And with the rapid development of gas-insulated combined electrical appliances (GIS) in recent years, S...
