Abstract
A new energy low-temperature air energy heat pump generating device mainly comprises a heat absorber, a compressor, a sterling generating set, a throttle valve and pipelines connected with each other, accessories and a detection and control device, wherein a working medium is arranged in a closed system. The working medium absorbs heat energy in air through the heat absorber and is compressed into high-temperature high-pressure air state by the compressor (2); the high-temperature high-pressure working medium flows to the sterling generating set for heat discharge and condensation as a heat source, and enters the sterling generating set through the throttle valve for heat absorption and evaporation as a cold source; the sterling generating set generates electricity by using temperature difference; and the working medium enters the heat absorber to form a closed circulation system. Without a cold source outside the system, the low-temperature air energy heat pump generating device has high heat efficiency, simple structure, low investment and low cost.

Technical field
The utility model relates to a kind of generation of electricity by new energy device, and especially a kind of Cryogenic air can heat pump generating apparatus.
Background technology
The electric energy overwhelming majority all derives from the sun, no matter wind energy, water energy, biological energy source or fossil energy--coal, oil, natural gas, combustible ice.In today of energy growing tension, the clean utilization of power technology of new renewable green comes into one's own day by day.Now, in the new forms of energy, solar power generation technology such as waterpower, wind-force and solar power generation directly utilize technology-photocell, minute surface heat build-up generation technology quite ripe; The hydroelectric power development potentiality are little; And wind-force, sunlight too disperses, and what make wind-force, solar power generation utilizes directly that floor space is huge, one-time investment is high.Earth atmosphere every day is all at the energy that repeats to absorb and disperse solar radiation, and the environment liquid-airborne solar thermal energy that absorbs solar heat energy upgrades every day, and is almost inexhaustible.Thereby people are in the environment liquid that steps up to study new indirect utilization solar energy-airborne thermal power generation technology.Wherein low-temperature solar energy heating power generation technology is the new and high technology of potential future.At present, known heat-pump-type Cryogenic air can Blast Furnace Top Gas Recovery Turbine Unit (TRT) adopt the low temperature solar thermal energy in the heat pump enriched air By to adopt the Rankine cycle system generating again.Wherein heat pump mainly comprises compressor, condenser, flow controller, evaporator; The Rankine cycle electricity generation system mainly comprises condenser, circulating pump, evaporator, expansion power generation unit.This heat-pump-type low-temperature solar energy heating power generation technology not only operation of heat pump needs consumed energy, and a large amount of heats that condenser consumed of Rankine cycle electricity generation system can flow out electricity generation system and are not used effectively.Its complex structure, investment is high, especially the heat efficiency is low.
Summary of the invention
Can the generating device structure complexity in order to overcome existing heat-pump-type Cryogenic air, investment is high, the low deficiency of the heat efficiency especially, the utility model provides a kind of Cryogenic air energy heat pump generating apparatus, this Cryogenic air can need not the outer low-temperature receiver of system by heat pump generating apparatus, heat efficiency height, simple in structure, investment is low, cost is low.
The technical scheme that its technical problem that solves the utility model adopts is: this Cryogenic air can mainly comprise heat dump, compressor, stirling generator group, choke valve by heat pump generating apparatus; It also comprises pipeline, annex and detection and the control device that is connected in the system, and working medium is arranged in the closed system.Working medium can absorb low temperature environment fluid-heat energy in air through heat dump becomes the HTHP gaseous working medium by compressor compresses, and HTHP working medium is made thermal source and flowed into stirling generator group heat release condensation; And condensation working medium enters stirling generator group heat absorption evaporation through the choke valve throttling as low-temperature receiver again, and the stirling generator group is utilized temperature difference acting generating; Working medium enters heat dump again and further absorbs low temperature environment fluid-heat energy in air and become the HTHP gaseous working medium by compressor compresses, makes thermal source then again and flows into stirling generator group heat release condensation, has formed closed cycle system like this.The compressor of this Cryogenic air energy heat pump generating apparatus also can be the multi-stage compression unit.This Cryogenic air can the heat pump generating apparatus heat dump be the high-efficiency heat pipe heat exchanger.Also can be connected between this Cryogenic air energy heat pump generating apparatus stirling generator group main shaft and the compressor main shaft.This Cryogenic air can heat pump generating apparatus also can be installed on car and boat and other plant equipment as direct driving force device or charging device.This Cryogenic air can heat pump generating apparatus by-product cold air.
The beneficial effects of the utility model are, this Cryogenic air can need not the outer low-temperature receiver of system by heat pump generating apparatus, heat efficiency height, simple in structure, investment is low, cost is low.
