Background

With the development of economy and the rapid increase of power demand in China, gas insulation equipment is widely used as core equipment for electric energy transmission and distribution due to the advantages of small occupied area, high reliability, small maintenance amount, electromagnetic environment friendliness and the like. Although the gas insulation medium has stable chemical properties and is not easy to decompose, when the gas insulation equipment has a discharge fault, the strong electromagnetic energy and high temperature which are locally generated can cause the decomposition of the insulation gas in different degrees, thereby generating substances with high corrosivity and toxicity; if the insulating gas which cannot be recycled after being used is directly discharged into the air, the health of equipment operators can be threatened; but also causes serious pollution to the atmospheric environment. Therefore, it is necessary to perform a cleaning process on the insulating gas which cannot be recovered and reused after use, and then to discharge the insulating gas.

At present, the insulating gas which cannot be recycled after being used is usually directly introduced into alkaline solution and then discharged, and the purification treatment only has a simple link, and if the pressure of the insulating gas is too high and the flow rate is too high, the gas cannot be effectively purified.
