The invention discloses a degassing device for gas-liquid separation and a gas-liquid separation method. The degassing device is provided with a vertical shell (9), an inlet pipe (1) and a liquid outlet pipe (2) are arranged at the lower portion of the shell, and a gas outlet pipe (3) is arranged at the upper portion of the shell. The degassing device is further provided with a floating ball valvecapable of controlling exhausting and gas-blocking of the gas outlet pipe. A vertical inner cylinder (7) is arranged in the shell, and the bottom of the inner cylinder is communicated with the inletpipe. The inner cylinder is internally provided with a stand column (60), and a spiral plate (6) is arranged between the inner side face of the inner cylinder and the side face of the stand column. Aspiral channel (5) is formed between the inner side face of the inner cylinder, the side face of the stand column, and the adjacent upper circle of spiral plates and lower circle of spiral plates, anda flow stabilizing area (10) is arranged between the tops of the spiral plates and the top of the inner cylinder. The invention discloses a method for adopting the degassing device to conduct gas-liquid separation. The degassing device is mainly applicable to gas-liquid separation in the technical field of liquid flow measurement, and can provide reliable guarantee for precise metering of a massflowmeter.
Description
technical field [0001] The invention relates to a gas eliminator for gas-liquid separation and a gas-liquid separation method in the technical field of liquid flow measurement. Background technique [0002] The mass flow meter is an important measuring instrument that can simultaneously measure the mass and density parameters of liquids. During the process of storage, pipeline transportation, loading and unloading of ships, loading and unloading trucks, etc., it is easy to form a two-phase fluid in which gas and liquid coexist. For example, the pumping and pumping of oil products between the pipeline and the oil tank in the petroleum industry, the rise and fall of the oil level in the storage tank, the radiation heating of the pipeline by sunlight, and the decrease of the static pressure head caused by overcoming frictional resistance along the line, etc. It causes the precipitation of light components in the oil and the formation of small bubbles distributed in the oil.
