Sulfur hexafluoride discharge degradation device and degradation method

The invention relates to the technical field of gas purification devices, in particular to a sulfur hexafluoride discharge degradation device and a degradation method. The discharge degradation device comprises a gas supply unit, a stirring and mixing unit and a discharge reaction unit, the gas supply unit comprises a gas supply main pipe, and an inert gas supply module, a sulfur hexafluoride supply module and an external gas supply module which are connected with the gas supply main pipe; the inert gas supply module, the sulfur hexafluoride supply module and the external gas supply module can supply inert gas, sulfur hexafluoride gas and reaction gas to the gas supply main pipe respectively, and the inert gas, the sulfur hexafluoride gas and the reaction gas are stirred by the stirring and mixing unit, so that the inert gas, the sulfur hexafluoride gas and the reaction gas can be fully mixed. The discharge reaction unit is used for carrying out discharge reaction on the mixed gas, so that ...
