Centrifugal separation pipe, gas-liquid separation device and refrigerating system with device

Abstract

The invention discloses a centrifugal separation pipe, a gas-liquid separation device and a refrigerating system with the device. The centrifugal separation pipe comprises a spiral pipe body, the inlet end of the pipe body is higher than the outlet end, the centrifugal separation pipe is characterized in that the section of the pipe body is rectangular, the extending direction of the inlet end is located in the tangential direction of the pipe body; the outlet end is bent in the direction of the spiral axis and right faces the axis. The centrifugal separation pipe can conduct effective gas-liquid separation on fluid through the rectangular pipe body. According to the gas-liquid separation device, a centrifugal separation pipe, a flow guide component and a heat exchange component are used for carrying out gas-liquid separation on fluid for multiple times, and the gas-liquid separation effect is improved; after the gas-liquid separation device is adopted by the refrigerating system, the refrigerating efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and relates to a gas-liquid separation technology, in particular to a centrifugal separation tube, a gas-liquid separation device and a refrigeration system with the device. Background technique [0002] Most of the compressors used in the refrigeration system are displacement compressors, such as piston compressors and screw compressors. The low-temperature and low-pressure refrigerant gas is compressed into high-temperature and high-pressure refrigerant gas after consuming mechanical work in the compressor. Then in the condenser, the normal temperature and high pressure refrigerant liquid is condensed. If there is still liquid in the gas sucked by the compressor, the liquid will rapidly vaporize after absorbing heat in the compression cavity of the compressor. Since the volume of the refrigerant gas per unit mass is several times that of the liquid, the volume of the refrigerant expands ra...

AI Technical Summary

Problems solved by technology

[0003] The refrigerant liquid at room temperature and high pressure must be throttled before entering the gas-liquid separator. The liquid refrigerant after throttling is cooled and depressurized. , the temperature of the refrigerant will increase slightly when throttling, resulting in flash gas of the refrigerant during throttling, which reduces the cooling efficiency per unit of refrigerant

Usually, in order to reduce the flash gas when the refrigerant liquid is throttling, an economizer, a subcooler and other equipment are added to the refrigeration system, but the complexity of the refrigeration system is increased due to the addition of equipment, and the pipelines of the refrigeration system are also increased. Valves, Instruments, etc.
