Abstract
The utility model provides a new energy resource air energy air liquefaction separating device, comprising two parts, wherein a first part is an air liquefaction separating unit which is the same as a conventional air liquefaction separating unit; and the second part is an air energy power unit comprising a booster pump, an expansion engine, and a throttle valve. After pressurization in the booster pump, a liquid state working medium, such as liquid nitrogen or liquid air from a fractionation system, loses cold and absorbs heat through an air inflow heat exchanger of the air liquefaction separating unit and becomes high-pressure supercritical fluid, which enters into the expansion engine for expansion and temperature and pressure reduction and then returns to the fractionation system after throttling and cooling for circulation. The air energy air liquefaction separating device can obtain additional power and cold through the air energy power unit and thus reduces energy consumption of an air liquefaction separating system greatly. Power of the expansion engine can be used for generating electricity which, except for self-use, can be transmitted to a power grid.
