External floating roof storage tank sealing ring wireless monitoring device and density detection process

Abstract

The invention discloses a wireless monitoring device for a sealing ring of an external floating roof storage tank and a process for detecting the density, particularly relates to the field of combustible gas concentration monitoring, and aims to provide a wireless monitoring device for the concentration of combustible gas in the sealing ring of the external floating roof storage tank, which can monitor the concentration of oil gas in the sealing ring of the external floating roof storage tank in real time. The wireless monitoring device for the concentration of the combustible gas in the sealing ring of the external floating roof storage tank comprises a sampling system, a detection system and a wireless transmission system, the sampling system comprises a plurality of sampling pipelines, an electromagnetic valve, an air extracting pump and a standby air extracting pump, the detection system comprises a gas sensor, and the wireless transmission system comprises a GPRS antenna and wireless relay equipment; each sampling pipeline is connected with an electromagnetic valve, the output end of each electromagnetic valve is connected with a sucking pump and a standby sucking pump, the sucking pump is electrically connected with the second relay, and the standby sucking pump is electrically connected with the first relay.

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 ...
