Abstract

The invention discloses an automatic gas-liquid separation method, which belongs to the technical field of gas-liquid separation, and is characterized by comprising the following steps that S1, pressurized liquid-containing sample gas is introduced into an interlayer; S2, the liquid phase is discharged from a liquid outlet in the bottom of the outer cylinder through a circular through hole; S3, in the process that the liquid phase is discharged from the liquid outlet, the buoyancy of the stainless steel buoy is reduced along with reduction of the liquid phase, a round through hole in the organic silica gel sealing head is blocked by a spherical plug, and linear sealing is recovered; and S4, the liquid phase stops being continuously discharged from the liquid outlet, so that the liquid phase is always kept in the cylinder bottom space, the gas phase is prevented from flowing out from the liquid outlet, and automatic gas-liquid separation is realized. According to the separation method, when the liquid phase is not completely discharged, linear sealing of the stainless steel buoy can be recovered, the liquid phase exists in the bottom space of the buoy all the time, and therefore automatic gas-liquid separation is achieved, the separation effect is guaranteed, the separation efficiency is improved, the method is suitable for being used in anti-explosion and poisonous and harmful production fields, and the applicability is enhanced.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation, in particular to an automatic gas-liquid separation method. Background technique [0002] The gas-liquid separator can be installed at the inlet and outlet of the gas compressor for gas-liquid separation. It can be used for gas phase demisting of various gas washing towers, absorption towers and desorption towers. The gas-liquid separator can also be used in various industrial and civil occasions such as gas dust removal, oil-water separation and liquid removal of impurities. [0003] The commonly used separation method of gas-liquid separator is gravity sedimentation method. Due to the difference in specific gravity between gas and liquid, when the liquid flows together with the gas, the liquid will be subjected to a greater force of gravity, resulting in a downward velocity, while the gas still flows in the original direction, that is, the liquid and the gas are in the gravitati...
