The gas-liquid separator 2 comprises at least two air return pipes 3, and the second end orifice of the pressure balance pipe 5 and the orifice of the air return pipe 3 farthest from the bracket 4 are positioned at the same height in the axial direction of the shell 1.

Preferably, the pressure balance pipe 5 is a rigid connection pipe, and the rigid structural characteristics of the pressure balance pipe 5 can be utilized to more effectively realize pressure balance at two ends and reduce the vibration intensity generated to the pressure balance pipe 5 in the gas flowing process.

The second end pipe orifice of the pressure balance pipe 5 and the pipe orifice of the air return pipe 3 farthest from the support 4 are correspondingly arranged, so that the two pipe orifices of the pressure balance pipe correspond to the support 4 with the largest vibration influence and the air return pipe 3 farthest from the support 4, and the pressure balance is realized to the greatest extent from the gas-liquid separator 2 as a whole.

The gas-liquid separator 2 comprises at least two air return pipes 3, a plurality of pipe orifices are formed in the second end of the pressure balance pipe 5, the plurality of pipe orifices of the pressure balance pipe 5 and the air return pipes 3 are arranged in a one-to-one correspondence mode, and the pipe orifices of the pressure balance pipe 5 and the pipe orifices of the air return pipes 3 which are correspondingly arranged are located at the same height in the axial direction of the shell 1.
