Concentrating solar thermal-collecting panel

Abstract

The invention discloses a concentrating solar thermal-collecting panel which is an advanced solar thermal-collecting device and designed according to the directional light reflection principle. The concentrating solar thermal-collecting panel is characterized in that after passing through a glass plate and then reaching a concentrating reflecting surface, the sunlight is reflected to a thermal-collecting tube by way of regulatory focusing, so that the density of light on the surface of the thermal-collecting tube is greatly increased, and the ambient temperature of the thermal-collecting tube is multiplied, therefore, the thermal-collecting effect of the thermal-collecting tube is good. The concentrating solar thermal-collecting panel disclosed by the invention has the advantages that: the concentrating solar thermal-collecting panel is easy to install and use and resistant to high pressure, and can produce high pressure steam; the basic problems of scouring and bathing can be solved, and the problems of drinking water heating and food cooking also can be solved; the concentrating solar thermal-collecting panel can be used with floor heaters or heating apparatuses for winter heating; and the most important is that the concentrating solar thermal-collecting panel can be subjected to large-scale assembly so as to produce high pressure steam for driving a steam turbine to carry out power generation.

Description

Technical field [0001] The invention belongs to a high-temperature and high-pressure solar thermal collector plate. Background technique [0002] Now, there are no more than two types of solar heat collection equipment: one is glass tube heat collection tube, which is cheap but cannot operate under pressure, and the heat collection effect is average, and 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. Contents of the invention [0003] Aiming at the shortcomings of the origin...

Problems solved by technology

[0002] At present, there are no more than two types of 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.
