The invention discloses
gas pipeline cleaning equipment for an inner floating top
storage tank. The
gas pipeline cleaning equipment includes a gas-liquid separation tank, a liquid level
transmitter, avalve group, and a controller, wherein the top of the gas-liquid separation tank is connected to the tops of a swept pipeline and the inner floating top
storage tank through a first pipeline and a second pipeline, the bottom of the gas-liquid separation tank is connected to the bottom of the inner floating top
storage tank through a third pipeline, the liquid level
transmitter is used for detecting the liquid level of the gas-liquid separation tank and transmitting the liquid level to the controller, the valve group comprises a first control valve, a second control valve, a third control valve and a
check valve, the first control valve is arranged on the first pipeline, the second control valve is arranged on the second pipeline, the third control valve and the
check valve are arranged onthe third pipeline, the third control valve is close to the gas-liquid separation tank, the
check valve is close to the inner floating top storage tank, and the controller is used for receiving the liquid level and controlling the open and close of the first control valve, the second control valve and the third control valve according to the liquid level. The
gas pipeline cleaning equipment can effectively achieve two-phase separation of gas and liquid and avoid the disturbance of the pipeline cleaning gas to the
liquid phase.
