ORC magnetic levitation power generation system capable of achieving gradient utilization of residual pressure of medium and low temperature geotherm

Abstract

The invention relates to an ORC magnetic levitation power generation system capable of achieving gradient utilization of residual pressure of medium and low temperature geotherm. The ORC magnetic levitation power generation system comprises an evaporator for evaporating a working medium, a condenser for condensing the working medium, cooling equipment for cooling the condenser, and a power generator; the power generator comprises a primary turbine and a secondary turbine; the cooling equipment is connected with the secondary turbine; a working medium steam outlet of the evaporator is connectedwith an inlet of the power generator; an outlet of the power generator is connected with the condenser; and an outlet of the condenser is connected with a liquid working medium inlet of the evaporator. The gaseous working medium respectively performs expansion work in the two turbines, wherein the priamry turbine drives the power generator to generate power through a coupling; the secondary turbine drives an impeller to rotate through the coupling to accelerate an air flow on the surface of the condenser, strengthen the heat exchange capacity of the condenser and reduce the condensation temperature and condensation pressure, so that the pressure difference and temperature difference between the inlet and the outlet of the magnetic levitation power generator are increased and the power generation efficiency of the magnetic levitation power generator is improved.

Description

technical field [0001] The invention relates to the technical field of geothermal energy power generation, in particular to an ORC magnetic levitation power generation system utilizing medium and low temperature geothermal residual pressure cascades. Background technique [0002] With the depletion of fossil energy, renewable energy is in the ascendant, and geothermal energy, as a safe and clean resource with huge reserves, has become a hot spot of scientific research. Overall, the geographical distribution of geothermal resources in my country is uneven. my country's high-temperature geothermal fields are mainly distributed in plateau areas such as Tibet and Yunnan; mid-to-low temperature (temperature below 150 degrees Celsius) geothermal fields are widely distributed in southeastern coastal areas, plain areas, hilly areas, and inland sedimentary basins. Although the high-temperature geothermal development technology is mature, it is not suitable for large-scale developmen...
