Abstract

The invention provides a new energy low-temperature Brayton dual-cycle power generating device. The device comprises two closed cycle power generating systems, wherein one working medium is subject to heat absorption through a heat absorber, and flows sequentially to a compressor, a condenser, a working medium pump, an evaporator and an expansion generator set to form a first close cycle power generating system; the other working medium sequentially flows through the condenser, the compressor and the expansion generator set to form a second closed cycle power generating system; the heat absorber and the evaporator can absorb low-temperature heat energy in air and water; and the high-temperature high-pressure working medium in the first closed cycle power generating system exchanges heat with the low-temperature low-pressure working medium in the second closed cycle power generating system in the condenser.

Summary of the invention
In order to overcome high, the low deficiency of the thermal efficiency especially of existing heat pump type low temperature heat energy electricity generating device investment, the invention provides the two circulation electric generating apparatus of a kind of low temperature Bretton, the two circulation electric generating apparatus of this low temperature Bretton need not the outer low-temperature receiver of system, and thermal efficiency height, investment is low, cost is low.
The technical solution adopted for the present invention to solve the technical problems is: the two circulation electric generating apparatus of this low temperature Bretton mainly comprise heat absorber, compressor, condenser, working medium pump, vaporizer, expansion power generation unit; It also comprises pipeline, annex and detection and the control gear that is connected in the system, and it has two closed circulation power generation systems, and working medium is arranged in the closed system.In the first closed circulation power generation system, flow to compressor behind the heat energy of working medium in heat absorber absorption air, in the water, the High Temperature High Pressure working medium of compressed machine compression flows to heat release condensation after the low-temp low-pressure working medium heat exchange in the condenser and second closed cycle system, condensation working medium is pressed into vaporizer through working medium pump again, the heat energy heating liquid refrigerant that vaporizer can absorb in low temperature environment fluid-air, in the water becomes high-pressure gaseous working medium, and high-pressure gaseous working medium enters expansion power generation unit expansion acting generating then; The outlet of expansion power generation unit is a low-temp low-pressure working medium, low-temp low-pressure working medium flows to compressor behind the heat energy in heat absorber absorption air, in the water again, expansion power generation unit outlet pressure has formed the first closed circulation power generation system like this by the inlet pressure decision of compressor.In the second closed circulation power generation system, working medium absorbs the heat energy of the high temperature refrigerant in first closed cycle system through condenser, and compressed machine is collapsed into high-pressure gaseous working medium, and high-pressure gaseous working medium enters the acting generating of expanding of expansion power generation unit then; The outlet of expansion power generation unit is a low-temp low-pressure working medium, low-temp low-pressure working medium flows to compressor behind the heat energy of the high temperature refrigerant in absorption first closed cycle system again in condenser, expansion power generation unit outlet pressure has formed the second closed circulation power generation system like this by the inlet pressure decision of compressor.The compressor of the two circulation electric generating apparatus of this low temperature Bretton also can be the multistage compression unit; And its primary compressor also can directly be connected the outlet of expansion power generation unit, to keep expansion power generation unit outlet low pressure.Also can be connected between the two circulation electric generating apparatus expansion power generation set main shafts of this low temperature Bretton and the compressor main shaft.The heat absorber of the two circulation electric generating apparatus of this low temperature Bretton is high-efficiency heat pipe heat exchangers.The two circulation electric generating apparatus of this low temperature Bretton also can be installed on car and boat and other machinery as direct driving force device or charging unit.The two circulation electric generating apparatus of this low temperature Bretton also can be used for low temperature heat resource power generations such as waste heat used heat underground heat.The two circulation electric generating apparatus by-product cold air of this low temperature Bretton.
The invention has the beneficial effects as follows that the two circulation electric generating apparatus of this low temperature Bretton need not the outer low-temperature receiver of system, thermal efficiency height, investment is low, cost is low.
