Abstract
The utility model provides a disc type solar heat electricity generating system heat collector. Heat collecting performance is improved. The disc type solar heat electricity generating system heat collector comprises a heat collecting cavity and a heat absorbing coil arranged in the heat collecting cavity. A transparent body is arranged on an opening part of the heat collecting cavity, and the opening part is used for light rays to be emitted in. The heat collecting cavity is arranged to be a sealing cavity and is filled with air. The heat collecting cavity is provided with an air channel which is provided with a safety valve. The safety valve is arranged in a mode that when air pressure in the heat collecting cavity is larger than designed air pressure, the safety valve is opened so that the air can be exhausted from the heat collecting cavity through the air channel. The air protects the heat absorbing coil from high temperature and prevents the heat absorbing coil from being etched in an oxidation mode, meanwhile the requirements on materials of heat absorbing coil are lowered, the air lowers the pressure difference in and out of a heat pipe, the thickness of the wall of the heat absorbing coil can be reduced, heat exchanging effect is improved, the heat collecting cavity is sealed, no convection exists between the heat collecting cavity and the outside, and accordingly heat loss is lowered.
Description
Technical field
The utility model relates to the heat collector of solar heat power generation system.
Background technology
Development along with World Economics, the whole world is growing to energy demand, traditional fossil energy more and more can not satisfy human demand for development, the reserves of fossil energy are exhausted just day by day, and use fossil fuel to bring serious consequence as environment for human survival in a large number, because a large amount of fossil energy that uses produces a large amount of greenhouse gases, formed very serious atmosphere pollution at present.From all multifactor consideration of energy supply, solar energy is undoubtedly the desirable green energy resource of the compound strategy of sustainable development.
Solar electrical energy generation has multiple mode, and wherein topmost have solar energy thermal-power-generating and a photovoltaic generation.Photovoltaic cell is with high costs, and cost of electricity-generating is much higher than heat generating, and the broadcasting and TV conversion efficiency of photovoltaic cell still lower (about 10%).Solar heat power generation system has the advantage that cost is low, efficient is high.Solar heat power generation system can be divided into three kinds of modes such as tower type focusing, slot type focusing and the focusing of dish formula.The dish formula focuses on that to have a system scale little, and has the characteristics such as ability of efficient, modularization and composition hybrid power system.
The disc type solar energy heat generating system is that the solar energy that dish formula condenser is assembled is focused on the heat collector at its focus place, heat collector absorbs this part highdensity energy, be converted into heat energy, and be transferred to hot machine, as Stirling engine, drive generator for electricity generation, thereby be electric energy with thermal power transfer.
The disc type solar energy heat generating system comprises concentrator, tracking control system, heat collector, thermoelectric conversion device, power-converting device, AC stabilizer, energy storage device, battery etc.
Heat collector has heat collector cavity, heat absorption coil pipe usually, and heat collector cavity has the peristome of the light incident of converging for concentrator.The applicant's utility model people finds, though the disc type solar energy heat generating system with Stirling engine as thermo-electric converting device, have high conversion rate, also having is worth the place of further improving.
The utility model content
The purpose of this utility model is to provide a kind of heat collector of disc type solar energy heat generating system, to improve solar collecting performance.
Heat collector for the disc type solar energy heat generating system of realizing described purpose, comprise heat collector cavity and be arranged on the interior heat absorption coil pipe of heat collector cavity, wherein, the peristome for light incident of heat collector cavity is provided with the transparent body, this heat collector cavity is set to airtight cavity, be filled with gas in the heat collector cavity, heat collector cavity disposes gas passage, this gas passage is provided with safety valve, this safety valve was opened when this safety valve was configured to the interior air pressure of this heat collector cavity greater than design pressure, so that this gas can be discharged from heat collector cavity from this gas passage.
Described heat collector, wherein, the wall inboard, chamber of this heat collector cavity is attached with heat-insulation layer.
Described heat collector, wherein, this transparent body is concavees lens, convex lens or planar lens.
Described heat collector has following characteristics:
One, the coil pipe of protection heat absorption at high temperature prevents oxidized corrosion, reduces the heat absorption coil pipe simultaneously to the requirement of material;
Two, reduce the heat pipe inside and outside differential pressure, but absorbing heat disk thickness of pipe wall attenuate improves the heat exchange effect;
Three, because not having convection current with the external world, reduce heat loss.
Aforementioned purpose of the present utility model, characteristics and advantage will describe in detail in embodiment described later.
Description of drawings
Fig. 1 is the schematic diagram of heat collector among the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings; set forth more details in the following description so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations under the situation of the utility model intension, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
Heat collector cooperates with concentrator, and the sunshine that concentrator converges incides in the heat collector.
As shown in Figure 1, heat collector comprises heat collector cavity 10, is arranged on the heat absorption coil pipe 2 in the heat collector cavity 10.Heat collector cavity 10 has the peristome 4 of the light incident of converging for concentrator, peristome 4 is by transparent body sealing 1, so that heat collector cavity 1 becomes airtight cavity, the transparent body 1 allows that sunshine passes, basically do not reduce the energy that penetrates light, it mainly plays sealing function, and the transparent body 1 can be concavees lens or convex lens or planar lens.The chamber wall of heat collector cavity 10 is made of shell 11 and shell 11 inboard additional heat-insulation layers 3.Air inlet pipe 14 penetrates into the inboard from the outside of heat collector cavity 10, and feeding has gas, this gas to be but is not limited to inert gas from air inlet pipe 14, perhaps nitrogen.Magnetic valve 6 on the air inlet pipe 14 cuts out after air inlet pipe 14 charges into enough gas in the heat collector cavity 10, so that gas remains in the heat collector cavity 10, the overflow valve 5 on the air inlet pipe 14 is as safety valve, in case the air pressure in the heat collector cavity 10 is greater than design pressure, overflow valve 5 is just opened, drainage pressure.Installation position at the transparent body 1, shell 11 seals by sealing gasket 21, so that heat collector cavity 10 becomes airtight cavity.
Gas in the heat collector cavity 10 that is airtight cavity, its effect has: one, the coil pipe 2 of protection heat absorption at high temperature, prevent oxidized corrosion, reduce the requirement of 2 pairs of materials of heat absorption coil pipe simultaneously; Two, reduce heat absorption coil pipe 2 inside and outside differential pressures, thereby but feasible heat absorption coil pipe 2 wall thickness attenuates improve the heat exchange effect; Three, because not having convection current with the external world, reduce heat loss.In technology in the past, heat absorption coil pipe 2 must be considered wall thickness, to bear the big pressure that heat-transfer working medium forms.
In Fig. 1, the shape of heat collector cavity 1 is schematically, and its concrete structure arranges according to the practical project needs.
