An Adaptive Super-Efficient Gas-Liquid Separator for Parallel Compressor Units

Abstract

The invention discloses an adaptive ultra-high-efficiency gas-liquid separator for a parallel compressor unit, which comprises a casing, a separation chamber is arranged in the casing, an inlet pipe, an air outlet pipe and an oil return pipe, and the separation chamber includes a gravity separation chamber and an oil return pipe. The centrifugal separation chamber arranged around the separation chamber; the outlet end of the inlet pipe communicates with the inlet end of the centrifugal separation chamber; the air outlet pipe is used to output the gas passing through the gravity separation chamber; the housing is also provided with a diversion chamber located below the separation chamber and the collection chamber located below the diversion chamber; the lower ends of the gravity separation chamber and the centrifugal separation chamber communicate with the diversion chamber; a deflector is provided in the diversion chamber to divert the gas separated by the centrifugal separation chamber to the gravity The separation chamber and the liquid are diverted to the collection chamber; one end of the oil return pipe is connected with the collection chamber, and the other end is connected with the air outlet pipe. The invention has the advantages of small size, convenient modular assembly, high separation efficiency, avoiding harmful overheating of suction, ensuring reliable oil return within the full load range, and the like.

Description

technical field [0001] The invention relates to a gas-liquid separator, in particular to a gas-liquid separator used in parallel compressor units. Background technique [0002] Parallel compressor unit has the outstanding advantage of high operating efficiency under partial load, and is widely used in the field of refrigeration and air conditioning. In order to cope with terminal load changes or system needs, parallel compressor units need to be equipped with gas-liquid separators. [0003] The existing gas-liquid separator structure has the following problems: 1. The principle of gravity separation is adopted, and the external dimensions are large, which is not convenient for modular assembly of the unit; 2. The separation chamber has a built-in spiral coil, which aims to heat the separated liquid to make it vaporize , the volume of the spiral coil is large, and the high-pressure liquid will continue to heat the suction of the compressor. Under the action of the heat excha...

AI Technical Summary

Problems solved by technology

[0004] The present invention proposes an adaptive ultra-high-efficiency gas-liquid separator for parallel compressor units. The purpose is to: (1) reduce the size of the device and facilitate modular assembly; The temperature rises and the oil cooling load increases; (3) Solve the problem that the oil cannot be returned when the flow rate of the outlet pipe is lower than the oil-carrying speed under partial load conditions
