Embodiment Construction
[0018] Below in conjunction with drawing, the present invention is further described:
[0019] Self-driven absorption heat pump refrigeration steam power plant such as figure 1 As shown, the system consists of a heat pump refrigeration cycle and a steam power cycle.
[0020] The heat pump refrigeration cycle is composed of generator 1 refrigerant end, compressor 2, generator 1 heat source end, throttling and pressure reducing valve 3, evaporator 4, absorber 5, solution pump 7, solution heat exchanger 6, and generator 1 refrigeration The agent end and the pipeline are connected in sequence. The dilute refrigerant solution is heated and evaporated by a high-temperature heat source in the generator 1 to generate medium-pressure refrigerant vapor. The concentrated solution enters the solution heat exchanger 6 to exchange heat with the dilute solution from the absorber 5 and then enters the absorber 5. The medium-pressure refrigerant The steam is compressed, pressurized and heate...

The invention discloses a method for providing steam power and a device thereof, and belongs to the technical field of power. Steam condensation latent heat of a thermal compression heat pump refrigeration cycle is recovered to serve as a driving heat source of a thermal compression heat pump refrigeration system for driving the thermal compression heat pump refrigeration system; the high-temperature output heat source of the thermal compression heat pump refrigeration system is taken as a heating heat source for heating a working medium for driving a steam power cycle; the low-temperature output heat source of the thermal compression heat pump refrigeration system is taken as a cold source for condensing steam exhaust of the steam power cycle in order to output power outwards. Thus, a small amount of mechanical power is consumed, and a heat source and a cold source are provided for the steam power cycle. The cold source can be used for providing a cold source for the steam power cycle, and the residual part can be supplied to the outside to realize power-cold combined supply. The economical problem of the conventional power system consisting of a heat pump cycle and a power cycle is solved, large-scale green power is realized, and green development is truly realized.
Description
technical field [0001] The invention relates to a steam power method, which belongs to the technical field of steam power. Background technique [0002] General steam power output devices (steam engines, steam turbines) use fossil energy, nuclear energy, solar energy and other energy sources for heating. The combustion of fossil energy will cause serious environmental pollution. The safety control requirements of nuclear energy devices are high, and the investment in solar energy collection devices is large. [0003] CN940254 discloses a power system device composed of a combination of a power cycle system and an absorption refrigeration system. This power system uses absorption refrigeration to provide low-temperature cold coal to cool exhaust steam discharged from steam power machinery. This technology can utilize low Grade heat source provides power. CN940254 also discloses a power system device composed of a power cycle system, a compression heat pump system, and an abs...
