Sulfur hexafluoride degradation treatment device based on gliding arc discharge and method thereof

Abstract

The invention discloses a sulfur hexafluoride degradation treatment device based on gliding arc discharge and a method thereof. The sulfur hexafluoride degradation treatment device comprises a spiral electrode spray gun, and the spiral electrode spray gun is connected with a host through a cable at the tail of the spiral electrode spray gun; the cable comprises a high-voltage wire, a grounding wire and a spray gun gas inlet pipe, and is used for providing high-frequency voltage and introducing sulfur hexafluoride gas into a reactor in the spiral electrode spray gun; high-frequency discharge occurs between a high-voltage electrode and a grounding electrode in the spiral electrode spray gun, dense plasmas are generated in a discharge area, and sulfur hexafluoride gas collides with the plasmas in the discharge area to be 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 liquor absorption tank which is used for absorbing toxic acid gas in decomposition tail gas of sulfur hexafluoride. According to the invention, the technical problems that the sulfur hexafluoride gas is only recovered and is not degraded or the degraded sulfur hexafluoride gas is low in treatment capacity, low in degradation rate and free of a tail gas collecting device at the present stage can be solved.

AI Technical Summary

Benefits of technology

The technical effect described in this patents are that these inventions have improved performance for removing pollutants from gases like hydrogen fluorides (HF) while being able to efficiently break down them under specific conditions such as temperature and pressure. Additionally, they integrate an apparatus called a device called a sliding arcade discharger, allowing users to easily change settings during operation based upon their needs. They provide stability over time when used together with different types of chemicals. Overall, these improvements enhance overall cleanliness capabilities and reduce costs associated therewith.

Problems solved by technology

Technological Problem: Current methods for treating gases containing fluorous acid called persistently existing in atmospheric environments include decompositing them into harmless materials like hydrogen chlorine hydride (HC), carbon dioxide, nitrogen, argon, etc., while maintaining their stability during use. However, these conventional techniques require large amounts of energy input and may result in environmental pollution if they break down harmful substance residues within the environment's ozone layer.
