Description

Flame arrester and pipeline equipment Technical Field The utility model relates to the technical field of flame arresters, in particular to a flame arrestor and pipeline equipment. Background In the industrial fields of petrochemical industry, chemical industry, gas and the like, various inflammable and explosive gases or liquid-gas mixtures and particulate matters are often required to be conveyed in a circulating mode in a pipeline through pipelines, and the fire risk is greatly increased due to the fact that the media are inflammable and explosive substances. Therefore, fire protection devices such as flame arresters are required to be installed in the pipelines to prevent fire. The principle of flame arresters is to pass the flame through a small passage of the flame arrestor element and cool the flame in the passage. When the flame is divided and reduced to a certain extent, the heat removed through the channels is sufficient to lower the temperature below the ignition point of the combustibles, extinguishing the flame.
