背景技术Background technique

太阳能作为新能源的一种，发电主要分为广电转换以及光-热-机械能-电转换，前者广电转换需要使用高成本的光伏板，而且光伏板制造过程中本身就能耗巨大，而且会排放大量温室气体；后者光-热-机械能-电转换主要是定日镜与集热塔组合，需要占用大量土地，适宜在荒漠戈壁地区设置，但是定日镜控制系统耗资巨大。利用空气受热膨胀推动发电机叶轮转动发电的太阳能烟囱日益成熟，但是占用土地面积较大。As a kind of new energy, solar energy is mainly divided into radio and television conversion and light-thermal-mechanical energy-electricity conversion. The former radio and television conversion requires the use of high-cost photovoltaic panels, and the photovoltaic panel manufacturing process itself consumes a lot of energy, and will emit A large amount of greenhouse gases; the latter light-heat-mechanical energy-electricity conversion is mainly a combination of heliostats and heat collection towers, which requires a lot of land and is suitable for setting in the desert Gobi area, but the heliostat control system costs a lot. The solar chimney that uses the thermal expansion of the air to drive the generator impeller to rotate and generate electricity is becoming more and more mature, but it occupies a large area of land.

Moreover, traditional solar chimneys rely solely on the thermal expansion of the air to drive the generator turbine, and the power generation efficiency is low.

A pipe is connected between the tank and the fresh water tank.

上述方案中联合发电与蒸馏技术效果，到那时没有对太阳能烟囱的工作进风量和温度进行控制，导致整体集热效果低下，而且无法根据环境变化以及发电需求进行调节。The combined power generation and distillation technology effect in the above scheme, the working air intake and temperature of the solar chimney were not controlled at that time, resulting in a low overall heat collection effect, and it could not be adjusted according to environmental changes and power generation needs.

当光照强度降低或者被云层遮挡时，一级液体储热罐与集热棚内实时循环连通保持温度稳定，当一级液体储热罐温度降低至设定温度时，二级熔融储热罐向一级液体储热罐释放热量，反向操作即可存储热量。上述方式能够提高整体集热效果联合浓缩卤水，同时还能根据环境变化以及发电需求进行调节。When the light intensity decreases or is blocked by clouds, the first-level liquid heat storage tank and the heat collecting shed are connected in real-time to keep the temperature stable.
