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 combined heating and power system and belongs to the technical field of combined cooling, heating and power and absorption heat pumps. An absorption heat pump cycling system comprises 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, a power machine provides low-temperature heat load for the second generator through an exhaust steam channel and provides low-temperature heat load for an evaporator through a first steam channel, the generator communicates with the outside through a high-temperature heat medium channel, the absorber and a condenser communicate with the outside through heated medium channels, the second absorber communicates with the outside through a cooling medium channel, and the combined heating and power system is formed.
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...
