Description

Gas-liquid separator

Technical Field

The utility model relates to the technical field of separators, in particular to a gas-liquid separator.

Background

The main mode of gas-liquid separation in industry at present is realized by gravity sedimentation or simple gas-liquid separation internals. The gravity sedimentation requires a longer residence time, thus leading to a huge size of the separator tank, high cost of the tank, high installation difficulty, large occupied area, relatively poor separation effect, and generally separation of droplets with a size of more than 100 microns. The tank size can be properly reduced by using simple gas-liquid separation internals such as wire mesh separators, but droplets of sizes above 15-30 microns can also be separated.

Further, the upper part of the tank body is provided with a gas outlet.

Further, a bottom liquid outlet communicated with the liquid storage space is arranged at the bottom of the tank body.
