Description

Multi-lens spherical structure solar heat collection system

technical field

This design is a multi-lens spherical structure solar heat collection system, which is applied to solar power generation, heat collection and other systems, and belongs to the field of energy saving technology.

Background technique

Solar power generation is an emerging renewable energy technology. At present, the industrialized applications are mainly solar photovoltaic power generation and solar thermal power generation. Solar photovoltaic power generation has the characteristics of modularization of battery components, convenient installation and maintenance, and flexible use methods. It is the most widely used technology for solar power generation. Solar thermal power generation heats the medium through the concentrating heat collection system, and then uses traditional steam power generation equipment to generate electricity. In recent years, industrialization demonstration projects have begun to increase. However, the main component of solar photovoltaic power generation, solar cells, has high production costs and short design life, and what is more serious is the high pollution cost of producing solar cells; while solar thermal power generation can avoid the above disadvantages, but its equipment is large in size. The use is greatly restricted by the terrain, and it is difficult to promote.

Utility model content

The purpose of the utility model is to provide a small-volume, high-efficiency high-efficiency convex lens-like spherical structure solar heat collection and power generation system.

The system includes a spherical housing consisting of an upper hemispherical lens, a lower hemispherical mirror and a support member. Among them, the area enclosed by the spherical shell is the working fluid evaporation system, and the center of the working fluid evaporation system is the steam generator.

The working method is characterized in that: sunlight is collected in the generator of the working medium steam generation system through the lens; and the lower hemispherical reflector reflects the unused light back to the spherical steam generator to reheat the working medium.

In addition to generating electricity, the solar heat collection system can also be directly used for seawater desalination. The seawater enters the generator directly from the bottom pipe, and after being heated by the sun, the water evaporates, and the water is drawn out from the top pipe to condense into the required fresh water. This device is more convenient and reliable than the previous photovoltaic power generation system or photothermal power generation system. Since there is no sunlight tracking device, it has strong resistance to harsh weather conditions such as sandstorms and humid air, so it can be used in deserts, oceans, mountains, etc. Areas with harsh climates but abundant light resources; and the cost of the system is lower than the previous two systems, and it is more convenient to promote large-scale applications; and the system can be miniaturized, has lower requirements on terrain and other conditions, and can be installed in high-rise buildings in cities The top and other similar areas; and the main raw material glass for the production of the system can be seen everywhere, and the system can even be produced by recycling waste glass, which further reduces the production cost of the system.

Detailed ways

As shown in Figure 1, the utility model is composed of an external lens, a support, an internal evaporation system and a bottom reflector. The light heat is gathered by the convex lens, and finally converged into the glass bulb container of the working medium steam generation system, while the unused light is reflected back to the center of the evaporation system through the reflector, and the working medium is heated to generate working medium steam. The working medium steam is guided to the outside through the top pipe of the steam generation system for the next step of operation. The lost working fluid is supplemented by the lower pipe of the glass container. So as to achieve the purpose of continuously generating working medium steam in the whole system.
