Gas purifying device and gas purifying method thereof

Abstract

The invention relates to a purifying device and method, and in particular relates to a gas purifying device and a gas purifying method thereof. The device comprises a ventilating opening connected with an air chamber; the ventilating opening is provided with a self-sealing valve. The device further comprises a main ventilating pipeline, an air feeding module, a purifying module and an air discharging module; the ventilating opening is formed in the head end of the main ventilating pipeline; the tail end of the main ventilating pipeline is respectively connected with the head end of the air feeding module and the tail end of the air discharging module; the tail end of the air feeding module is connected with the head end of the purifying module; the tail end of the purifying module is connected with the head end of the air discharging module. By virtue of the gas purifying device and the gas purifying method, gas in an insulation gas chamber of a high-pressure switching device can be purified through one ventilating opening and the normal power consumption of a user is not influenced, so that the purpose of purifying high-pressure switch insulation gas can be achieved, the emission of toxic and harmful gas can be reduced, the ecological environment is protected, and the social benefit and economic benefit are greatly increased.

Description

technical field [0001] The invention relates to a purification device and a purification method, in particular to a gas purification device and a gas purification method. Background technique [0002] In recent years, gas insulated switchgear has been rapidly promoted and applied in my country, especially with the construction and transformation of urban power grids in my country, rail transit and large industrial and mining enterprises, etc. With new and higher requirements such as working conditions, the domestic demand for high-performance and high-quality inflatable cabinets is becoming stronger and stronger. [0003] In the above gas insulated switchgear, sulfur hexafluoride gas, nitrogen gas or mixed gas is often used as the insulating medium of the switchgear. Taking sulfur hexafluoride gas as an example, although it has good electrical insulation performance and excellent arc extinguishing performance, if it is not recovered and regenerated in the correct way, it wil...
