Abstract

The invention relates to a flame arrester which comprises a flame arrester body, wherein the flame arrester body is supported by a bracket; an upper baffling net and a lower baffling net are arranged in the flame arrester body; a flame arresting substance is filled between the upper baffling net and the lower baffling net; an air outlet is formed on the side wall of the upper part of the flame arrester body and communicated with an explosion-proof device; the explosion-proof device is arranged at the upper part of the upper baffling net in the flame arrester body; an air inlet is formed at the bottom part of the flame arrester body; and a check valve clack is arranged at the air inlet. The flame arrester provided by the invention prevents explosion accidents caused by tempering, has a good flame arresting effect and is safe and reliable.

Description

technical field [0001] The invention relates to a flame arrester, which belongs to the technical field of flame arresters. Background technique [0002] Flame arresters are often used in metallurgical, chemical and other industries where pipeline fires may occur. In the prior art, the fire arrester structure of the flame arrester is gravel type, wire mesh type or corrugated type, which is suitable for combustible gas pipelines. In a chemical plant with a harsh environment or a cement plant with a lot of dust, there is a problem of tempering, which poses a safety hazard. At the same time, the fire-stopping speed is slow and the effect is not ideal. Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide a flame arrester with good fire arresting effect, safety and reliability. [0004] The technical scheme adopted in the present invention i...
