Gas Circulation Apparatus for Degradation of Sulfur Hexafluoride Gas, and Gas Scrubbing Mechanism

A gas circulation apparatus for degradation of a sulfur hexafluoride gas, comprising:

• gas cylinders, gas circuits arranged on the gas cylinders, and relief valves, electromagnetic flowmeters, temperature sensors, flow sensors and electromagnetic valves arranged on the gas circuits sequentially;
• a discharge reactor, an input end of the discharge reactor communicating with output ends of the electromagnetic valves;
• a gas scrubbing mechanism, an input end of the gas scrubbing mechanism communicating with an output end of the discharge reactor;
• a buffer gas bag, an input end of the buffer gas bag communicating with an output end of the gas scrubbing mechanism;
• a buffer gas chamber, an input end of the buffer gas chamber communicating with an output end of the buffer gas bag, and an output end of the buffer gas chamber communicating with the gas circuits;
• and a pressure gauge arranged on the buffer gas chamber.
