Description
技术领域technical field
本实用新型涉及热电技术领域，更具体的说，是涉及一种太阳能热电冷联产系统。The utility model relates to the technical field of thermoelectricity, more specifically, relates to a solar heat, electricity and cold cogeneration system.
背景技术Background technique
热电厂夏季运行时普遍存在热负荷短缺的问题，导致发供电煤耗增多，热电厂的技能优势不断下降,热电厂内部供热机组因热负荷不足而停运,使机组及供热系统的很多设备闲置,运行效率低下,造成大量资源浪费和经济损失。为了解决此问题,研究者们在热电联产的基础上利用蒸汽乏汽或抽汽来驱动吸收式制冷机制冷,发展热、电、冷联产系统。There is a common problem of thermal load shortage during thermal power plant operation in summer, which leads to an increase in coal consumption for power generation and a continuous decline in the technical advantages of thermal power plants. The internal heating units of thermal power plants are shut down due to insufficient thermal load, leaving many units and heating systems idle. Low efficiency, resulting in a lot of waste of resources and economic losses. In order to solve this problem, on the basis of combined heat and power generation, researchers use steam exhaust or steam extraction to drive absorption refrigerators for cooling, and develop heat, electricity, and cold cogeneration systems.
热、电、冷联产系统可以使热电厂的热负荷相对较为平稳，提高热电机组的负荷因子，因而热经济性较高。目前国内已经投运的联产系统中，高温蒸汽在汽轮机中做功产生电能，之后乏汽在冬天可以通过与二次网换热后对用户进行供暖，夏季可以将热能用于驱动吸收式制冷系统，为冷用户供冷。由于在实际应用中并没有充分的考虑能源的综合利用问题，能耗较高，直接影响了联产系统的经济性。The heat, electricity, and cooling cogeneration system can make the heat load of the thermal power plant relatively stable, improve the load factor of the thermal power unit, and thus have high thermal economy. In the cogeneration system that has been put into operation in China, the high-temperature steam works in the steam turbine to generate electricity, and then the exhaust steam can be used to heat the user after exchanging heat with the secondary network in winter, and the heat energy can be used to drive the absorption refrigeration system in summer , to provide cooling for cold users. Since the comprehensive utilization of energy is not fully considered in practical applications, the energy consumption is high, which directly affects the economy of the cogeneration system.
