Beschreibung
Zusammenfassung:	The invention discloses a hydrogen-containing pipeline valve chamber vent gas recovery device and method. The hydrogen-containing pipeline valve chamber vent gas recovery device comprises a trunk pipeline; a trunk line block valve is arranged on the trunk line pipeline, an upstream trunk line pipeline section and a downstream trunk line pipeline section which are located on the two sides of the trunk line block valve are communicated through an external trunk line bypass, and two bypass block valves are arranged on the trunk line bypass; two compression recovery branch pipes are communicated with the main line bypass section between the two bypass block valves, a compression recovery device is connected between the other ends of the two compression recovery branch pipes, and a bypass emptying valve is arranged on the main line bypass section between the two compression recovery branch pipes. The recovery device and method are suitable for the hydrogen-containing pipeline with the hydrogen content larger than
