A key step in the measurement of most online gas analyzers (infrared, magnetic oxygen, thermal conductance, etc.) is to collect the measured gas to a detector of the analyzer through a sampling pipeline (stainless steel pipeline or PTFE) for detection or measurement of different principles, and the sampling pipeline takes a quantitative sample gas from a hole of a pipeline of a process device. The detector is typically a charged device and is susceptible to explosion and ignition if the sampled gas is of a flammable or explosive nature. If measures are not taken, dangerous sources in the explosion-proof analyzer are not isolated timely, internal explosion or fire can spread and spread, or can be returned to an external pipeline until the original process pipeline and process equipment are damaged, and larger dangerous accidents are caused. Similarly, if the external pipeline fires and explodes, the dangerous source can be transmitted to the analyzer to cause the explosion damage of the analyzer, which is expensive and expensive, so we propose an explosion-proof flame arrester for the analyzer to solve the problems.
