Description

Technical Field

[0002] At present, the emergency flare gas source of atmospheric ammonia tank mainly uses LNG natural gas as the combustion medium, which consumes a lot. The main cost in daily operation is high and wastes national energy. Therefore, recycling and reusing synthetic venting air and relaxation gas is an important measure to increase production and save. Recycling and reusing the venting gas waste gas produced by the production of synthetic ammonia system as the gas source for flare combustion provides a good opportunity to save costs and reduce environmental pollution. When recycling and reusing the waste gas, the gas guide pipe is required to guide the waste gas until the waste gas is transmitted to the vicinity of the flare LNG pipeline. When installing existing pipelines, they often use one-piece pipelines or extended pipelines. One-piece pipelines are not easy to repair after problems occur in the pipeline and need to be replaced as a whole. Extended pipelines are often connected by fixed connection or clamping. Fixed connection is also not easy to replace, and the clamping method is easy to produce gaps during connection, resulting in gas leakage. Therefore, it is necessary to solve the problem of how to achieve rapid splicing of the gas guide pipe and ensure the air tightness of the gas guide pipe connection. Utility Model Content
