Description
技术领域 technical field
本实用新型公开了一种用于太阳能储能系统的熔盐电加热器，属于电加热设备。 The utility model discloses a molten salt electric heater used in a solar energy storage system, which belongs to electric heating equipment.
背景技术 Background technique
利用熔盐存储“热能”是太阳能发电厂的一项能源储存技术。太阳能光热系统使用反射镜聚焦太阳光，形成足够高的温度，产生蒸汽驱动涡轮机。对比把阳光直接转换成电能的传统光伏，太阳能热利用技术的优势之一，就是可以较为方便地储存热量，在需要时用来发电。在所有太阳能热电厂，一些热量都被存储在流体中，这些流体在系统中循环。这就可均衡日照的任何短期波动，让电厂在太阳落山后的一段时间，还可以发电。但是，增加存储系统，就可以让电厂在云层覆盖下运行更长一段时间，发电可以持续到深夜，甚至整个夜间。同时晚上可根据电网的峰谷电通过加热器进一步加热热煤提高热煤的温度。 Using molten salt to store "thermal energy" is an energy storage technology for solar power plants. Solar thermal systems use mirrors to focus sunlight, creating temperatures high enough to generate steam to drive turbines. Compared with traditional photovoltaics that directly convert sunlight into electricity, one of the advantages of solar thermal technology is that it can store heat more conveniently and use it to generate electricity when needed. In all solar thermal plants, some heat is stored in fluids that circulate through the system. This evens out any short-term fluctuations in sunlight, allowing the plant to generate electricity for periods after the sun has set. But adding a storage system would allow the plant to run under cloud cover for longer periods of time, producing electricity well into the night, or even throughout the night. At the same time, according to the peak and valley electricity of the power grid, the heater can further heat the hot coal at night to increase the temperature of the hot coal.
现有技术中，常用的熔盐电加热器由于结构原因，往往存在漏热现象发生，而且发热电阻丝未进行绝缘处理，常常造成事故发生。 In the prior art, the commonly used molten salt electric heater often has heat leakage due to structural reasons, and the heating resistance wire is not insulated, which often causes accidents.
