Abstract

The invention provides a combustible gas detection alarm. The combustible gas detection alarm comprises a gas suction pipeline, a combustible gas detection alarm host, a dustproof filter screen and aharmful gas absorption film, wherein the dustproof filter screen and the harmful gas absorption film are sequentially arranged in the gas suction pipeline, and sucked gas sequentially passes through the dustproof filter screen and the harmful gas absorption film and enters the combustible gas detection alarm host to be detected. By arranging the harmful gas absorption film, corrosive harmful gas can be absorbed, and corrosion damage of detection elements of the detector and catalyst poisoning are avoided, and therefore, the service life of the combustible gas detector is prolonged.

Description

technical field [0001] The invention relates to the technical field of combustible gas detection and alarm, in particular to a combustible gas detection and alarm device. Background technique [0002] Refinery fires are mostly caused by the leakage of combustible gas. When the combustible gas leaks in the production device, it combines with air to form an explosive gas mixture, which can easily cause fire and chemical explosion. However, most of the refinery equipment is under high temperature and high pressure. Once a fire breaks out at this time, the fire will spread rapidly, and there will be multiple combustion forms such as three-dimensional, large area, multiple fire points, re-ignition, and re-explosion, which will easily cause casualties and property. loss. Therefore, combustible gas leakage detection technology, as a technical means to ensure safe production in the petroleum industry, has attracted more and more attention. [0003] The catalytic combustion combust...
