碟式太阳能发电自然循环接收器 Dish Solar Power Natural Circulation Receiver

技术领域technical field

本发明涉及一种碟式太阳能发电自然循环接收器，用在碟式太阳能发电的场合。The invention relates to a dish-type solar power generation natural circulation receiver, which is used in the occasion of dish-type solar power generation.

背景技术Background technique

目前，石油、煤炭储藏量有限，价格上涨，以石油煤炭为燃料燃烧产生的CO2、SO2对环境产生很大的危害，危极人类的生存。利用太阳能发电，不消耗能源，没有废气排放，极具发展潜力和应用前景。碟式太阳能发电成本低，占地少，可广泛应用在农村、个人、小型企业。在碟式太阳能热发电系统中，是太阳能接收器实现塔式太阳能热发电最为关键的核心技术，它将定日镜所捕捉、反射、聚焦的太阳能直接转化为可以高效利用的高温热能，为发电机组提供所需的热源或动力源，从而实现太阳能热发电的过程。At present, oil and coal reserves are limited and prices are rising. CO 2 and SO 2 produced by the combustion of oil and coal are very harmful to the environment and endanger the survival of human beings. Using solar energy to generate electricity does not consume energy and has no exhaust emissions, so it has great development potential and application prospects. Dish solar power generation has low cost and occupies less land, and can be widely used in rural areas, individuals, and small businesses. In the dish-type solar thermal power generation system, it is the most critical core technology for the solar receiver to realize tower-type solar thermal power generation. It directly converts the solar energy captured, reflected and focused by the heliostat into high-temperature heat energy that can be efficiently used to generate electricity. The unit provides the required heat source or power source to realize the process of solar thermal power generation.
