The invention discloses a concentric pipe structure gas-liquid separator with a waste heat recovery function, and belongs to the technical field of gas-liquid separators. The concentric pipe structure gas-liquid separator comprises a barrel, a sealing cover, an oil blocking baffle, an oil blocking cover, a pipeline and a filter screen. A three-layer concentric pipe structure is adopted for heat exchange, a high-temperature and high-pressure refrigerant passes through a middle pipe cavity, namely a high-temperature medium pipe, and gas enters a low-temperature medium pipe on the second layer through the upper portion of a gas pipe on the outermost layer; and oil sucked in by an oil return hole in the lower portion of the low-temperature medium pipe and other formed low-temperature and low-pressure gas-liquid mixtures exchange heat with the high-temperature and high-pressure refrigerant, evaporation of low-temperature and low-pressure gas and liquid in the low-temperature medium pipe is accelerated through waste heat of the high-temperature and high-pressure refrigerant, and thus the low-temperature and low-pressure gas and liquid are better gasified and enter a compressor, and the working efficiency is improved. The three-layer concentric pipe structure avoids the use of a large number of pipelines, an inlet and an outlet are connected through the side face, vehicle integration is facilitated through side face connection, pipelines are saved, and cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of gas-liquid separators, in particular to a gas-liquid separator with a concentric tube structure with the function of recovering waste heat. Background technique [0002] In the refrigeration system, the refrigerant pipeline can be divided into high-pressure and low-pressure parts. The high-pressure refrigerant has a high temperature and needs a condenser for cooling, while the low-pressure refrigerant passing through the evaporator needs a gas-liquid separator to separate gas and liquid. Refrigerants, while liquid refrigerants need time and temperature to rise to evaporate and become gaseous before entering the compressor, avoiding liquid compression and prolonging the service life of the compressor. Existing products have extremely low outlet dryness due to evaporation at low temperatures, and existing products need to install two gas-liquid separators for separation during installation, or use pipeline ...
