Embodiment Construction
[0025] Such as Figure 4 Shown is a refrigeration system comprising a gas-liquid separator of the present invention, which is composed of a compressor 10 , a condenser 20 , an expansion valve 30 , an evaporator 40 , a gas-liquid separator 50 , and a control valve 60 . After being compressed in the compressor 1, the working fluid becomes a high-temperature and high-pressure gaseous state, then enters the condenser 2 for condensation, and becomes a supercooled state, and then passes through the throttling effect of the expansion valve 3 to become a gas-liquid two-phase flow into the Gas-liquid separator 4. The working medium is separated in the gas-liquid separator, the gas is discharged from the gas outlet, and the liquid is discharged from the liquid outlet. The liquid enters the evaporator, becomes a superheated gas after absorbing heat, mixes with the gas from the gas outlet of the gas-liquid separator, and flows into the compressor to complete the cycle.

The invention discloses a gas and liquid separator, which comprises a cylinder (51), a gas-phase and liquid-phase inlet (52), a gas outlet (54) and a liquid outlet (53). The gas-phase and liquid-phase inlet (52) and the liquid outlet (53) are arranged on the lower portion of the cylinder symmetrically and are tangent with the cylinder (51), and the gas outlet (54) is arranged at the top of the cylinder (51). By the cyclone separation technology, two-phase flow flows into the cylinder through the tangent inlet (52), and a strong cyclone is formed inside the cylinder, so that liquid with high density is thrown to a wall and discharged from the liquid outlet, and gas gathered at the center is exhausted from the gas outlet at the top. The gas-phase and liquid-phase inlet and the liquid outlet function equivalently, and accordingly the gas and liquid separator is convenient to operate and small in size.
Description
technical field [0001] The invention relates to a gas-liquid separator, in particular to a gas-liquid cyclone separator, and belongs to the technical field of gas-liquid cyclone separation. Background technique [0002] The existing cyclone separator usually has one or more two-phase flow inlets, a liquid outlet and a gas outlet, the inlet is located at the upper part of the separator cylinder, and the outlet is located at the lower part of the cylinder. It must be ensured that the two-phase flow fluid flows in from the upper inlet, and the separated liquid flows out from the lower liquid outlet. According to the retrieval of prior art, find a kind of column type gas-liquid cyclone separator, it has column type separating pipe, has gas-liquid mixture inlet pipe on the column type separating pipe upper part and gas-liquid mixture inlet pipe is inclined by The tangential inlet enters the column type separation tube, the gas outlet is located at the upper part of the column ty...
