Abstract

The cooling cycle system provided by the present invention includes: a mixed working medium refrigeration cycle circuit and a cooling cycle circuit; the mixed working medium refrigeration circuit includes a mixed working medium compressor (101), a mixed working medium condenser (102), a return heat exchanger (103), mixed working medium throttle valve (104); the brine-cooled circulation loop includes brine-driven pump (201), brine condenser (202), precision oil separation system (203) , regenerative heat exchanger (103), distributed heat exchanger (204) and feed gas pre-cooling separator (302), the cooling circulation system provided by the present invention utilizes the common or mixed working fluid with low freezing point The cold cycle is used as a load-cooling cycle, and it is driven by high-reliability general cooling temperature zone drive components, avoiding the use of low-reliability low-temperature circulation pumps, and can realize remote transmission of cold energy at -60°C or even liquid nitrogen temperature zones. The structure is simple and compact, and the cost is low. Inexpensive, high-efficiency operation; and non-flammable working fluid can be used in the load-cooling cycle, which has high safety in special occasions.

Description

technical field [0001] The invention relates to the technical field of load cooling, in particular to a load cooling cycle system. Background technique [0002] Mixed refrigerant refrigeration technology has been widely used in the liquefaction of natural gas since the 1970s, and has become the leading technology in the field of liquefied natural gas (LNG). However, there are limitations when cryogenic mixed refrigerant refrigeration technology is used in air liquefaction separation or oxygen liquefaction, etc., but the mixed refrigerant usually contains hydrocarbon flammable components. A spill, where hydrocarbons come into contact with Air Liquide (liquid oxygen), will react violently, posing serious safety concerns. Therefore, there are serious safety hazards in the direct application of the multi-component mixed refrigeration technology containing combustible components in low-temperature air liquefaction separation systems or oxygen liquefaction and other occasions. I...
