Abstract

The invention discloses a gas-liquid separator. The gas-liquid separator comprises a tank, wherein a gas-liquid separator inlet flow passage is arranged on the tank and is sequentially connected to apre-rotation section and a pre-rotation cavity; the middle part of the tank is a separation cavity; the lower part of the tank is a liquid storage cavity; a liquid discharging pipe located at the bottom communicates with the liquid storage cavity; a gas discharging pipe goes deep into the central position of the tank; the gas-liquid separator inlet flow passage is an injecting device with a swirling function; when a liquid working medium flows through an injecting nozzle, a gas working medium of an injecting hole is sucked, the liquid working medium and the gas working medium are mixed by a swirling generator and are pressurized at a diffusion section, and then the mixture is separated into liquid and gas under the action of centrifugal force; the liquid is discharged by the liquid discharging pipe in the liquid storage cavity, and enters an expansion valve; and the gas is discharged by the gas discharging pipe, and enters a compressor, thus, the primary injection and the gas-liquid separation are completed. The gas-liquid separator can improve the injection efficiency of a jet type refrigeration system, then improves the refrigeration efficiency, meanwhile increases the utilization rate of space of the system, enhances the compactness of the system, and has relatively high gas-liquid separation efficiency.

Description

technical field

[0001] The invention belongs to the technical field of jet refrigeration, in particular to a gas-liquid separator. Background technique

[0002] The ejector refrigeration system usually designs an ejector and a gas-liquid separator. The high-temperature and high-pressure gas refrigerant after being boosted by the compressor enters the condenser to condense and dissipate heat, and then accelerates and depressurizes in the ejector. The pressure difference between the outlet of the evaporator and the high-temperature refrigerant at the outlet of the evaporator pumps this part of the gaseous refrigerant, and enters the gas-liquid separator after mixing. The separated liquid refrigerant enters the expansion valve and the evaporator in turn for heat exchange, and the gaseous refrigerant Going back to the compressor to boost the pressure, the purpose of this design is to use the ejector to increase the pressure of the low-pressure gaseous refrigerant at the outlet o...
