Problems solved by technology
[0004] In the steam power plant, although the temperature difference between the exhaust steam of the power machine and the environment is small, the heat is huge, especially in winter, and the temperature difference between the low-pressure exhaust steam discharged by the steam power plant and the environment is often difficult to use; There is a heat transfer temperature difference between the gas and the power cycle steam that is difficult to effectively use, resulting in a low comprehensive energy utilization rate of the combined heat and power generation system, and bringing certain restrictions on the utilization of clean energy in the combined heat and power generation system

The invention provides a thermodynamic co-generation system, and belongs to the technical field of thermoelectric cold co-generation and absorption type heat pumps. An absorber, a second absorber, a generator, a second generator, a solution pump, a second solution pump, a solution heat exchanger and a second solution heat exchanger form an absorption type heat pump circulating system; a power machine provides low-temperature thermal load to the second generator via an exhaust passage; a coolant provides low-temperature thermal load to the second generator; the power machine provides low-temperature thermal load to an evaporator through a first steam channel; the generator comprises a high-temperature thermal medium channel; each of the absorber and a condenser comprises a heated medium channel; and the second absorber has a cooling medium channel, and the above mentioned channels communicate with the outer part to form the thermodynamic co-generation system.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of cogeneration of heat, electricity and cooling and absorption heat pump. [0003] Background technique: [0004] In the steam power plant, although the temperature difference between the exhaust steam of the power machine and the environment is small, the heat is huge, especially in winter, and the temperature difference between the low-pressure exhaust steam discharged by the steam power plant and the environment is often difficult to use; There is a heat transfer temperature difference between the gas and the power cycle steam that is difficult to effectively use, resulting in a low comprehensive energy utilization rate of the combined heat and power generation system, and bringing certain restrictions on the utilization of clean energy in the combined heat and power generation system. [0005] The present invention is based on the premise of efficient utilization of heat energy, takes full advant...
