Description

technical field [0001] The invention belongs to the field of combustible gas concentration monitoring, in particular to a wireless monitoring device for combustible gas concentration inside a sealing ring of an outer floating roof storage tank. Background technique [0002] During the design and construction of the external floating roof oil tank, in order to ensure that the floating plate can move up and down flexibly, a certain distance will be kept between the floating plate and the tank wall to form an annular space where the oil surface is exposed. In order to isolate the exposed oil surface in the annular space from contact with the atmosphere and prevent volatilization of oil and gas, a sealing device is installed between the floating plate and the tank wall. At present, the sealing device of floating roof tanks at home and abroad generally adopts the form of double sealing. The primary seal is used for the direct sealing of the oil surface and is the most important ...
