Description
技术领域technical field
本实用新型属于降温设备技术领域,具体涉及一种基于热能及风能驱动的电厂用冷却系统。The utility model belongs to the technical field of cooling equipment, in particular to a cooling system for power plants driven by thermal energy and wind energy.
背景技术Background technique
火力发电厂中冷却塔的工作原理是:室外空气经过冷却塔内,与高温水经过热湿交换后,温度上升,如果直接排到室外不仅会浪费掉从冷却塔塔体内带出来的热量,而且会白白的将水蒸气蒸发掉,造成大量能源的浪费。因此应当想办法将这些热能利用起来,将热能转化为其他能源来利用。通常在建火力发电厂的地方,风能都较为丰富,将风能和电厂的余热结合起来一起发电,就能为电厂提供丰富的电能,还能减少能源的浪费。The working principle of the cooling tower in the thermal power plant is: the outdoor air passes through the cooling tower, and after heat and moisture exchange with high-temperature water, the temperature rises. If it is directly discharged to the outside, it will not only waste the heat brought out of the cooling tower body, but also Water vapor will be evaporated in vain, causing a lot of waste of energy. Therefore, we should find a way to utilize these heat energy and convert heat energy into other energy sources for utilization. Usually, where thermal power plants are built, wind energy is relatively abundant. Combining wind energy and waste heat from the power plant to generate electricity can provide abundant electric energy for the power plant and reduce energy waste.
冷却塔冷却的水量大,高温循环水需要的冷量也就大,导致冷却塔的体积也比较大;将蒸发冷却冷水机组与冷却塔联合,将蒸发冷却冷水机组用于辅助冷却塔的降温,能够有效分担冷却塔的冷量,还能减小冷却塔的体积。The amount of water cooled by the cooling tower is large, and the cooling capacity required by the high-temperature circulating water is also large, resulting in a relatively large volume of the cooling tower; the evaporative cooling chiller is combined with the cooling tower, and the evaporative cooling chiller is used to assist the cooling of the cooling tower. It can effectively share the cooling capacity of the cooling tower and reduce the volume of the cooling tower.
在我国西北地区,干湿球温差大,干空气能、风能均比较丰富,完全有条件使用蒸发冷却冷水机组为电厂的循环水进行降温。特别是在夏季高温环境时,采用蒸发冷却冷水机组与冷却塔联合共同为循环水降温,能保证循环水的冷却效果,从而保证在高温环境时,降低系统背压,提高汽轮机发电效率,降低发电煤耗。In Northwest my country, the temperature difference between dry and wet bulbs is large, and dry air energy and wind energy are relatively abundant. It is completely possible to use evaporative cooling chillers to cool down the circulating water of power plants. Especially in the high temperature environment in summer, the evaporative cooling chiller unit and the cooling tower are used to jointly cool the circulating water, which can ensure the cooling effect of the circulating water, thereby ensuring that in the high temperature environment, the system back pressure is reduced, the steam turbine power generation efficiency is improved, and the power generation is reduced. Coal consumption.
