Abstract

The invention discloses a crude oil chemical engineering tank field gas detection system which comprises a ball valve, an anti-explosion wiring box and a PLC. The inlet end of the ball valve is connected with a gas inlet. The outlet end of the ball valve is connected with the inlet end of a first electromagnetic valve. Six connecting structures of the ball valve and the first electromagnetic valve are arranged and connected in parallel. The outlet end of the first electromagnetic valve is connected with a filter. Two outlet ends of the filter are arranged, one outlet end of the filter is connected with the inlet end of a needle valve, the outlet end of the needle valve is connected with a bypass outlet, the other outlet end of the filter is connected with the inlet end of a fine filter, the outlet end of the fine filter is connected with the inlet end of an electric pump, the outlet end of the electric pump is connected with one end of a three-way valve, the other ends of the three-way valve are connected with standardization openings. The problem of various gas sampling under the high-temperature, high-pressure, high-humidity and high-corrosion environment is solved, control is more convenient and intelligent, and systematized and centralized management is convenient.
