Description

A kind of solar energy thermal energy focus system

Technical field:

The utility model relates to a kind of solar energy thermal energy focus system, realize that with the mode of simple economy comparatively dish formula or disc type solar energy follow the tracks of, described solar energy thermal energy focus system relates to also that hot accumulator, solar water heater, miniature solar boiler are, the miniature solar water treatment system comprises seawater desalination system and the heat collector of middle-size and small-size solar thermal power generation system and solar energy thermal-power-generating factory.

Background technology

Generally comparatively complicated its light harvesting heat collector of existing dish formula or disc type parabolic reflector Salar light-gathering tracking system moves similar parabolic microwave aerial along with paraboloidal moving, heavier if desired light harvesting heat collector or needs connect external pipe make whole device very complicated with high costs, reliability and stability are also relatively poor, make it be difficult to apply.

Existing dish formula or disc type parabolic reflector Salar light-gathering tracking system do not bother application surface extremely narrow because the light harvesting heat collector does not make its energy carry in the fixed position very much.For what make that the light harvesting heat collector adopts at present on a fixed position is that so-called tower light harvesting collecting system is reflected in the fixing scope separately with the multiaspect reflective mirror, perhaps use so-called slot type light harvesting collecting system, these two kinds of application that system has had morely, but this type systematic generally all is that large-scale or medium-and-large-sized system can't miniaturization.

It collects existing solar energy Related product solar device and is equipped with and does not inequalityly have standard to say, and standardized production can be done by solar energy thermal energy focus described in the utility model system, can make different models according to different purposes, its size also can be made unified several standard convenient constructions, described solar energy thermal energy focus system can parallel with one anotherly become the solar energy collector of various uses and size, described solar energy collector can be made all kinds of solar products as vitals, comprising the miniature solar boiler, the solar energy generator can the additional heat hydrophone, can add the solar energy heat-storage system, can add solar energy indoor heat insulating heating system and miniature solar water treatment system and comprise seawater desalination system or the like novel solar product.

Existing solar energy Related product does not also have the product of solar boiler, has only solar cooker and the user of solar cooker must use to have influenced and uses and promote under burning sun, the utility model is because the light harvesting heat collector is hard-wired its jet chimney of miniature boiler that can be installed as also can fixedly mount and make it become the miniature solar boiler, this miniature solar boiler can be opened up purposes extremely widely, makes the mankind can not use the gas of the solar steam cooking significantly reducing carbon containing under burning sun, liquid or solid fuel provides a new direction for reducing carbon emission; Described miniature solar boiler can also become the pyroreaction still of solar energy photocatalytic hydrogen manufacturing, and made hydrogen can instead of natural gas culinary art fuel also can be the deposit fuel of fuel cell.

Existing solar energy thermal-power-generating factory owner will be to use the slot type parabolic reflector, its advantage is that its light harvesting heat collector is that the heat-conducting oil pipes of fixing can make the comparatively simple cost of single unit system lower like this, shortcoming is that optically focused makes that than relative disc type parabolic reflector is much lower final temperature output is lower, if and its light harvesting heat collector of existing disc type parabolic reflector is to move along with paraboloidal moving to be used for heating high temperature heat conductive oil to being brought the deuce to pay to make cost high, so solar energy thermal-power-generating factory abandons using, and the utility model light harvesting heat collector is fixed, the heat collector that the parabolic reflector of alternative slot type becomes solar energy thermal-power-generating factory is used for heating high temperature heat conductive oil, perhaps become the solar thermal collector that the hot power plant of solar groove type heat-conducting oil pipes back segment optically focused heats up, make its final temperature output significantly be higher than the parabolic reflector temperature output of single slot type, thereby thereby obvious improvement of whole solar energy thermal-power-generating factory's generating efficiency reduced cost.

The utility model parabolic reflector under the driving of traction electric machine can be that swing is followed the tracks of at the center with the axle center, and parabolic reflector can also be that the center rotates tracking with the sleeve pipe under the driving of motor simultaneously.

Additional parabola can be installed in order to increase reflective area by system described in the utility model, can increase the parabolic reflector area and can also come the whole paraboloidal center of gravity of balance.

Light harvesting heat collector described in the utility model is if middle-size and small-size thermoelectric (al) generator, its colling end can be a water-cooled, can leave in after the cooling water of described water-cooled is heated and make described a kind of solar energy thermal energy focus system both can generate electricity in the attemperater also can also to can be used as indoor warming thermal source simultaneously as the solar water heater hot-water supply.

Light harvesting heat collector described in the utility model is if thermoelectric (al) generator, and the heat of its cooling water can use the water at low temperature evaporation technique to make desalinization; Perhaps the working medium of described thermoelectric (al) generator can be with the clean seawater that does not have solid impurity and organic impurities, and evaporation and condensation owing to seawater in power generation process make desalinization produce drinkable fresh water.

Light harvesting heat collector described in the utility model needs attemperator can be installed in order to be incubated, and described attemperator can be that the glass evacuated stay-warm case of high light transmittance makes the heat of described light harvesting heat collector be maintained.

System described in the utility model can add heat-storing device in order to make to use when the sun sets, the ergastic substances of described heat-storing device can use energy storage materials such as conduction oil, phase-change material, mesohigh steam or low-melting-point metal.

The utility model is because the light harvesting heat collector is hard-wired its jet chimney of miniature boiler that can be installed as also can fixedly mount and make it become the miniature solar boiler, this miniature solar boiler can be opened up purposes extremely widely, makes the mankind can not use the solar steam cooking under burning sun; Described miniature solar boiler can also become the pyroreaction still of solar energy photocatalytic hydrogen manufacturing, and made hydrogen can instead of natural gas culinary art fuel also can be the deposit fuel of fuel cell.

Because the disc type parabolic reflector is more a lot of than high than the optically focused of slot type parabolic reflector, thereby the utility model light harvesting heat collector is fixed installation thereby can replaces trench light condensing system to become the heat collector raising conduction oil output temperature of solar energy thermal-power-generating factory simultaneously, and the solar thermal collector that perhaps becomes the heat-conducting oil pipes back segment optically focused intensification of the hot power plant of solar groove type is in order to promote the conduction oil output temperature and to improve the efficient of generating electricity.
