Abstract

The invention relates to the technical field of gas-liquid separation, and specifically discloses a gas-liquid separator. The gas-liquid separator comprises a separation tank, and a first partition plate and a second partition plate are arranged in the separation tank. The separation tank is sequentially divided into a first chamber, a second chamber and a third chamber along the axial direction,and a liquid retention device is arranged in the first chamber. The liquid retention device is arranged in the separation tank, and the liquid retention device directly faces a gas-liquid inlet of a gas-liquid mixture of the separation tank. When a pump body is started or is switched from a low gear to a high gear, the flow velocity of the gas-liquid mixture in the separation tank is instantly increased, the air pressure is increased, the expansion of a liquid retention sheet made of a flexible adsorption material is controlled by utilizing the change of the air pressure, and the liquid retention sheet is used for adsorbing the liquid in the gas-liquid mixture, so that the technical problem that the gas-liquid mixture is settled only by gravity and is difficult to separate thoroughly afterthe flow velocity is increased is solved.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation equipment, in particular to a gas-liquid separator. Background technique [0002] In the working environment of gas-liquid phase separation, such as steam recovery, tail gas treatment, etc., especially in the working environment of extracting flammable, explosive, toxic and other gases, the gas must go to the designated pipeline, and it is absolutely not allowed to leak out. It is discharged into other pipelines, so it is necessary to use a gas-liquid separator to separate the gas-phase substances from the liquid-phase substances, and then let the gas-phase substances enter the designated pipeline for collection, and the gas-liquid separator of this application is for A gas-liquid separator using gravity settling used in the pump body. [0003] Because the gas-liquid separation is carried out through the principle of gravity sedimentation, the gas-liquid cooling system used in the e...
