Abstract
The utility model relates to a low temperature power generating device for a CO* working medium geothermal pump. Water or geothermal water of 60 to 80 DEG C is discharged by utilizing a geothermal pump; and a CO* working medium is fully gasified at the temperature of 33 DEG C through heat exchange; and the supercritical fluid expands and does work at the temperature of 50 DEG C to push a turbine and generate power. A middle and small-sized power plant is established at the place where the geothermal condition is provided; no coal is required to be burned; the water resources are not polluted; and the geothermal special function is exerted fully. Compared with the effect of coal-fired power generation, the geothermal power generation saves 50 percent of consumption, reduces 50 percent of cost and 60 percent of floor area, saves 70 percent of resources and 90 percent of thermal efficiency, and increase 100 percent of economic benefit.
