Meanwhile, the process cost is low.

Description

The solar heat power apparatus

The utility model is a kind of solar heat power apparatus, and it is applicable to indoor heating power heating or provides hot water or steam, also applicable to generating and desalinization.

Hydrogen in the sun is inexhaustible, nexhaustible through the energy that thermonuclear reaction discharged, so the utilization of solar energy in recent years obtains attention more and more widely, comprising the use of solar water heater.The solar water heater that uses is to adopt the thermal-collecting tube type structure mostly now, because the heat exchanger effectiveness of solar energy heat collection pipe is lower, so the applicant proposed a utility application about the tower type solar heat collector, it is owing to not only be coated with absorbing membranous layer at the thermal-arrest inner wall of tower outer surface of Dewar structure, and being coated with the optical anti-reflective film layer at the inner surface of outer wall, heat exchanger effectiveness is significantly improved than tube type solar collector.However it is still the same with tubular type collector, only be water to be heated by the sunlight that direct absorption shines upon on the heat collector, the temperature difference of illumination temperature and water is less, so it is slower to heat up, timely additional heat after the heat radiation is admittedly can't realize the heat supply circulation, and no matter be tubular type or tower heat collector, its moisture storage capacity is all less, so, can't satisfy when big for the demand of hot water.

The purpose of this utility model provides a kind of novel solar heat power apparatus, and it can overcome existing shortcoming in the prior art, improves firing rate and moisture storage capacity.

The purpose of this utility model is achieved in that it comprises the heat collector of a back taper, heat collector is a Dewar structure, be coated with the composite absorption film and the anti-width of cloth is penetrated film at the outer surface of internal layer, be coated with optical anti-reflective film at outer field inner surface, between the inside and outside layer is the vacuum interlayer, it is characterized in that below heat collector, be provided with a plurality of automatic sun tracing focus lamps, focus point is at the conical surface of heat collector, heat collector is provided with upper hose and downcomer, upper hose connects the water source, and downcomer connects heat preservation storage water tank, and the vacuum interlayer of heat collector is connected with vavuum pump.

The utility model utilizes computer control, make focus lamp follow the tracks of the sun all the time, in heat collector, make heat collector solar light focusing, water is heated rapidly under the high temperature more than 500 ℃ especially as among the burning fire stove around placing, and the utility model is provided with heat preservation storage water tank, can be in cloudy day or uninterrupted hot water supply at night, heat collector volume of the present utility model in addition is big, can satisfy the hot water supply, the utility model operating cost is low simultaneously, does not pollute.

The maximum difference of the utility model and tube type solar collector is to have utilized focus lamp that illumination temperature is increased substantially, thereby can realize the Fast Heating of water, realizes the purpose of heating, acquisition steam and desalinization and generating, and the technology cost is lower simultaneously.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Fig. 1 is a general illustration of the present utility model.

Fig. 2 is the structural representation of the heat collector shown in Fig. 1.

I is a heat collector among Fig. 1, adopt overhead installation, a plurality of focus lamp IV are installed around below it, focus lamp is by computer control, all the time follow the sun, focus point is a vacuum pump chamber II in the bottom of heat collector on the cone of heat collector, the bottom is provided with the hot and cold water storage for the station III, and the water source of cold water and the heat preservation storage water tank of hot water are located at wherein.

As seen from Figure 2, the internal layer 5 of the heat collector of reverse taper adopts corrosion resistant plate to be welded, in order to gain in strength, be made into interior convex and be welded with reinforcement 15, be coated with the composite absorption film and the anti-width of cloth is penetrated film at the outer surface of cone portion, outer 2 adopt hard optical glass to make, for increasing its intensity, shape adopts outer convex, the surface has been coated with optical anti-reflective film within it, in, adopt seal gasket 3 or other mechanical system to clamp sealing between the skin, be provided with housing 1 in the heat collector outside, between housing and heat collector inner layer steel plate, be provided with heat-insulation layer 6, heat collector top is provided with overflow (vapour) valve 7, in heat collector, between the skin vacuum interlayer A, for making its vacuum remain on the 10-2 handkerchief for a long time, be connected with vavuum pump 10 by pipeline, heat collector is provided with upper hose (cold water enters) 8 and downcomer (hot water outflow) 12, be connected with heat preservation storage water tank 13 in the lower end of downcomer, between the outlet pipe of upper hose and heat preservation storage water tank, be connected with pipeline 14, and valve is housed, water cold in storage tank can enter heat collector by this pipeline and reheat, in heat collector, be provided with temperature sensor 4, for water can be heated quickly and evenly, be provided with the water wheels 9 of driven by motor, yet the workload in order to reduce to keep in repair can adopt radiating tube or fin to be with for water wheels, promptly on the heat collector internal layer 5 of reverse taper, weld many radiating tubes or sheet, these radiating tubes or sheet stretch to the central authorities of heat collector always, and heat is directly conducted in the water, and water is evenly heated.The utility model also is provided with lift 11 in addition, the lifting of personnel and article when being used to keep in repair.
