Abstract

The invention discloses equipment for detecting the concentration of combustible gas in a silo. The equipment comprises a gas collection device and a gas analysis device (20), wherein the gas collection device comprises at least one gas collection head (11) for collecting gas from at least one silo, a gas pump (12) and a first electromagnetic directional valve (13); the at leas one gas collection head (11) is connected with the inlet of the gas pump (12) through a pipeline; the outlet of the gas pump (12) is connected with the inlet of the first electromagnetic directional valve (13); the gas analysis device (20) is used for receiving the gas output by the outlet of the first electromagnetic directional valve (13) and collected by the at least one gas collection head (11), detecting the composition and concentration of the combustible gas in the gas, and outputting a signal indicating the composition and concentration. The equipment provided by the invention can detect the concentration of the combustible gas in the silo.

Description

technical field [0001] The invention relates to a device for detecting the concentration of combustible gas in a silo. Background technique [0002] Silo is a facility for storing bulk materials, which has the advantages of convenient use, environmental protection and reduced land occupation. However, silos, especially coal storage silos for storing coal, have not been used in ports. Coal storage silos need to pay attention to the problems of silo spontaneous combustion and explosion. Due to the small thermal conductivity of coal, the heat diffuses slowly to the surroundings, and the heat gathers in the coal pile to increase the internal temperature of the coal pile. When heated, coal piles release combustible gases such as carbon monoxide (CO), ethane (C 2 h 6 ), propane (C 3 h 8 ), the appearance of combustible gas can characterize the temperature of the coal pile. In addition, these flammable gases are mixed with air, and when the temperature, flammable gas concent...
