Technical field
The utility model relates to a kind of solar energy that utilizes as thermal source, and underground water is as the electricity generating device of low-temperature receiver.
Background technique
Solar energy and underground water are as pollution-free, and the energy that cost is low more and more is subject to people's attention.But at present solar energy and phreatic utilization are only limited to be used to produce hot water and regulate air, seldom have both are combined use, in particular for generating.
The model utility content
Technical problem to be solved in the utility model be that providing a kind of at the deficiencies in the prior art organically combines solar energy and underground heat, can also play the electricity generating device of the effect of energy-conserving and environment-protective in efficient power generation.
In order to realize the foregoing invention purpose, the technological scheme that the utility model adopted is:
A kind of device that utilizes solar energy and geothermal power generation, comprise solar concentrating collector, thermal accumulator, steam turbine, generator, condenser, underground water well, described solar concentrating collector, steam turbine, condenser form the closed loop by working fluid pump, the 3rd valve; The condensation water inlet/outlet of condenser inserts underground water well by drinking-water pipe and waste pipe, and drinking-water pipe is provided with water supply pump; Described thermal accumulator is in parallel with described solar concentrating collector by first valve and second valve; The power input shaft of generator connects with the pto of steam turbine.
The device using method of solar energy and geothermal power generation of utilizing of the present utility model is:
1. on daytime, close first valve and second valve, open the 3rd valve; About 20-30 ℃ liquid refrigerant is sent in the solar concentrating collector by the working fluid pump pressurization; Heating by solar energy makes working medium rise to 70-80 ℃, becomes superheated vapor;
2. the superheated vapor that flows out from solar concentrating collector enters steam turbine, promotes turbine acting output power, and this power can be converted into electric power output or directly output by generator; Be still overheated gas through working medium behind the steam turbine, pressure reduces, and temperature also reduces simultaneously;
3. the gaseous working medium of being discharged by steam turbine enters in the condenser, is drawn into the underground water cooling that comes by water supply pump; Underground water after the heat exchange is back in the underground water well again;
4. the working medium that flows out from condenser is sent into the solar concentrating collector by the working fluid pump pressurization, thereby finishes cyclic process, realizes the electric power output of system;
5. during night, close the 3rd valve, open first valve and second valve, utilize the heat that stores in the thermal accumulator to come heating working medium, the Working medium gas after heating enters steam turbine, promotes the turbine acting.Gaseous working medium by steam turbine is discharged enters in the condenser, is drawn into the underground water cooling that comes by water supply pump; Underground water after the heat exchange is back in the underground water well again, finishes a circulation.
The needed electric power of the utility model whole circulation process can be provided by system self fully, and additional power output is arranged, thereby can realize the generating of system.
The utility model adopts solar concentrating collector to absorb solar energy, and the temperature of working fluid is brought up to about 70-80 ℃, and superheated vapor drives steam turbine power generation, thereby improves systemic circulation efficient.System also will increase thermal accumulator on the basis of solar thermal collector.This thermal accumulator adopts heat pipe intensified heat transfer, and with high-efficiency thermal storage material heat accumulation.Daytime is by utilizing solar thermal collector hot machine working medium is heated and carrying out accumulation of heat by phase-change material.When not having thermal source and can utilize night, thermal accumulator is emitted heat, passes to the outer lower working fluid of temperature that passes through of pipe.Can also carry out generating state equally efficiently in night like this.
