Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a thermoelectric composite solar heat generation system,

Human beings are making use of fossil fuels to make a breakthrough. However, it can be said that it is facing the energy crisis in the 21st century to spend a limited amount of resources.

To overcome this, we are researching and developing alternative energy sources to maintain sustainable development and survival. The most effective and sustainable energy is solar energy.

Solar energy, which is mainly used in space, is solar energy, and more efficient and large-scale renewable energy is solar power.

Currently, solar power generation systems are classified into PTC (Parabolic Trough Concentrator), Tower (CRT, Central Receiver System), and Dish-Stirling.

Although the direct focusing method through the lens is much more effective than the conventional reflection focusing method, the manufacturing cost of the lens is excessively high, which makes it difficult to put it into practical use.

Producing this lens as a very cheap liquid lens (Bottle Lens) can realize high efficiency solar power generation.

In addition, thermoelectric power generation, a thermocouple, can directly generate electricity without energy conversion, resulting in more efficient high-efficiency power generation.

That is, the present invention relates to a method of direct power generation (thermoelectric power generation) through thermal electricity by high temperature obtained by directly condensing solar heat with a liquid flat convex lens which is more efficient and cheap than existing power generation methods,

The above is a general turbine power generation method that generates power by generating steam with high heat obtained by directly concentrating solar heat with the Bottle Plano Convex Lens.

There is a direct-condensing solar power generator in Moscow that uses a lens with a diameter of 30 to 50 meters. Although the effect of collecting solar energy is excellent, there is no practicality because the manufacturing cost of the lens is excessively high. The present inventor invented Bottle Lens while studying a cheap solar power generation system while viewing a Moscow famous cathedral painting in vodka as a gift.

It is an inexpensive bottle lense that collects solar heat directly and absorbs it into the endothermic system. It is stored in the heat storage system through the heat pipe heat transfer system, and heat is transferred to the power generation system through the heat pipe heat transfer system.

As in Korean Patent 10-0971160 (Solar Line Generator) and 10-1003294 (Solar Concentrator and Photovoltaic Power Generator Using It), 10-1053031 (Solar Generator), there is a technology of solar power generation, It may be difficult to spread to the market.

Korean Patent 10-0985591 (natural circulation type solar absorber for solar power generation),

Korean Patent No. 10-0997752 (solar concentrator module) is an invention relating to solar power and solar power generation, but its utility is inferior.

Korean Patent No. 10-0904666 (a photovoltaic device using a thermoelectric element) shows that condensed solar heat is directly transferred to a thermoelectric element, which requires supplementation of high temperature and ultra-high temperature, and difficulties in practical efficiency due to the difficulty in continuous efficiency of power generation ,

Korean Patent No. 10-1056941 (dish type solar collecting apparatus) is expected to have a difficulty in high efficiency due to the dish-type (Dish-Stirling)

Korean Patent No. 10-1019352 (condensing type solar and solar combined power generation device provided with light-transmitting collecting lens and auxiliary condenser lens) has difficulty in manufacturing cost and large size by adopting general convex lens and is practically used in the combined power generation method of solar and solar Expected difficulty in

do.

Korean Patent No. 10-1015608 (laminated thermoelectric generator using solar heat) uses a general convex lens and a reflector and directs condensed solar heat directly to a thermoelectric element, which is not practical.

Korean Patent No. 10-1001328 (combined power generation device using solar energy) is a power generation device in which a solar cell is combined with a thermoelectric power generation device that uses solar energy to be converged by a general convex lens, and it is a difficult invention in terms of continuous power generation and high efficiency .

Korean Patent No. 10-0999513 (combined power generation device using solar and solar heat) is a combined power generation device using a thermoelectric power generator around a solar cell, which is a main axis, and is a technology that is difficult to be put to practical use due to its sustainable high efficiency.

Although the inventions described above have their own technical characteristics, they are less competitive than other fossil or renewable energy sources and are highly questionable in terms of high efficiency.

Therefore, we have invented a high efficiency hybrid solar power generation system with high productivity and high efficiency that can compete with the general fossil energy market.

In the case of direct condensing of solar heat, the market competitiveness can be achieved only by producing expensive lenses at low cost.

Marketable lenses are liquid lenses (Bottle Lens), which can be used to manufacture low cost liquid flat convex lenses (Lens) and the challenges of maintaining the durability and transparency of these lenses at high temperatures and sunlight,

Heat transfer from the endothermic system to the heat storage system Heat transfer from the endothermic system to the heat storage system, which rotates along with the heat collection system along with the sunlight,

In addition, there is a problem of maintaining a special configuration and durability of the liquid prism lens and a problem of constructing a heat storage system capable of continuously generating electricity even when there is no sunlight by storing the high temperature of the endothermic system in the heat storage system,

The effective thermal insulation method of this system is an important task in completing this solar power generation system.

Inexpensive lenses can be made by constructing a bottle lens with a special structure. This liquid lens solves the problem of reducing the transparency and durability by generating water vapor by receiving sunlight.

This Bottle Plano Convex Lens is composed of a flat glass surface with convex curved surface and the other surface with a flat glass, which is welded, and the transparent space of this lens is filled with transparent ethylene glycol Fill the lens (Bottle Plano Convex Lens) with propylene glycol.

In order to solve the problem that transparency is lowered and durability is deteriorated due to generation of water vapor due to sunlight due to sunlight, an aqueous solution of 0.5 to 2% silicon dioxide (SiO2) is added to the liquid, The problem is solved by drilling holes on both sides and connecting the hose or pipe to circulate the liquid.

In the present invention, the first collection system, the second collection system, and the third collection system are installed in order to maximize the heat collecting effect by transferring heat from the minimum installation area to the heat absorption system at the central portion without loss.

In order to maximize the heat collection efficiency, the heat collection system must be accurately tracked at 90 ° to the sun,

By selecting and using various solar tracking systems known in the prior art such as a ball joint method in the middle of the heat pipe which is a heat transfer system for transferring the heat of the endothermic system to the heat storage system, To solve the above problems.

In the present invention, the structure of the heat collecting lens constituting the first heat collecting system is composed of a lens having a convex upper portion and a lower flat portion, and the heat collecting lens of the second heat collecting system has a flat upper surface, And the inner surface is convex. The reflector of the third heat collecting system is made of metal or mirror having excellent heat reflection efficiency and is formed of a parabolic parabolic reflector whose central part is empty in order to enhance the light condensing effect to the heat absorbing system .

 The prism lenses of the first and second collecting systems constitute a liquid inflow tube and an outflow tube as liquid lenses to circulate the liquid inside the lenses.

In order to minimize the heat loss in each process, the insulation is applied to the outside of the heat pipe and the outside of the heat storage system and the outside of the thermoelectric generation system with Aerogel.

In addition, when heat can not be collected because there is no sunlight, the heat transfer part is separated from the endothermic system or the heat storage system, or a special heat pipe is used to prevent heat from being radiated due to heat radiation.

In addition, a thermal storage system that can continuously generate electricity even without sunlight is a very important constituent. This thermal storage system can be used for crushed stones such as pyrophyllite, olivine, biotite, alkali pyroxene, biotite, It is preferable to construct a heat storage system by forming a shape of a cutting stone and a shape of a powder molded brick.

 Particularly, the thermal storage system of the present invention is constructed so as to have excellent thermal insulating function with an aerogel.

The inventive effect of thermocouple composite solar power generation system that is directly condensed with this bottle lens is accomplished by solving a high cost lens of high efficiency direct condensing solar power generation system with a very inexpensive liquid lens (Bottle Lens) It has the effect of competing in the market,

New and renewable energy is recognized as an inefficient system because it is more expensive than general fossil energy, and it has the effect of solving this perception.

It also has the effect of obtaining very effective electric energy in remote areas such as the Great Plains and the Ocean Desert Mountain where it is difficult to reach the electric energy.
