Compound solar collector

Abstract

The composite solar heat collector is a very advanced large-section solar heat collection equipment, which is designed by using the focusing principle of the parabola facing the light. When the sunlight shines on the parabolic concentrating reflective surface through the glass plate, it is regularly focused and reflected on the heat collecting tube, so that the light density on the surface of the heat collecting tube is greatly increased, and the ambient temperature is doubled, so its heat collection efficiency is high. Easy to install and use, high pressure resistant. This large collection of collectors can generate high-pressure steam. It can not only solve the basic problems of washing and bathing, but also solve the problems of drinking water and food cooking; it can also be used in combination with floor heating or heating for heating in winter; the most important thing is that it can generate high-pressure steam in large containers to drive steam turbines for power generation .

Description

Technical field [0001] The invention belongs to a large-section high-temperature and high-pressure internal reflection concentrating heat collector. Background technique [0002] At present, there are only two types of domestic solar heat collection equipment: one is the glass tube heat collection tube, which is cheap but cannot operate under pressure, the heat collection effect is average, and the water cannot be boiled. The other is the flat-panel solar heat collector, which is mainly imported technology. It can operate under pressure, but the cost is high, the heat collection effect is high, and the water still cannot be boiled. The limitations of these two heat collection methods are that the light density received by the heat collection tube is limited, and the ambient temperature is not high, resulting in a general heat collection effect. Therefore, the current solar water heater can only stay in a narrow range for washing and bathing. [0003] In foreign countries, t...

Problems solved by technology

[0002] At present, there are no more than two types of domestic solar heat collection equipment: one is the glass tube heat collection tube, which is cheap but cannot operate under pressure, the heat collection effect is average, and the water cannot be boiled.

The other is the flat-plate solar heat collector, which is mainly imported technology. It can operate under pressure, but the cost is high, the heat collection effect is high, and the water still cannot be boiled.

The limitations of these two heat collection methods are that the light density received by the heat collection tube is limited, and the ambient temperature is not high, resulting in a general heat collection effect. Therefore, the current solar water heater can only stay in the narrow range of washing and bathing.

[0003] In foreign countries, the deep utilization of solar energy has been taken as the research object, such as high temperature and high pressure thermal energy utilization and solar thermal power generation, but their collectors are bulky overall, and the concentrating surface is exposed to the air, which is easy to be polluted and oxidized, with low thermal efficiency and high cost. , so it cannot be actually promoted and utilized, but only stays on the basis of experiments
