Description
Technical field
The utility model relates to a kind of slot type heat collector, particularly a kind of slot type heat collector with the secondary condensation device.
Background technology
Along with development of science and technology, the progress of society, people begin to pay attention to the protection to natural resources, and the scientific research personnel of industry-by-industry is in the direction effort towards low-carbon (LC), environmental protection.In the prior art, the thermal power generation important status of still standing, however the thermal power plant need consume a large amount of non-renewable resources, and emission also is huge to the destruction of the Nature.
Solar energy is inexhaustible regenerative resource, and the today of reduce year by year at fossil fuel, the international energy situation is severe day by day, development and use solar energy is one of important channel of realizing energy supply diversification, assurance energy security.
As shown in Figure 2, the trough solar heat collector utilizes parabolic mirror to assemble the solar energy directional light in the prior art, thus heating working medium, high-temperature steam in the generation.Trough type solar heat-collector generally comprises: thermal-collecting tube, speculum, bracing or strutting arrangement and tracking means.But still there is a lot of defectives in trough type solar heat-collector at present; A/F such as existing heat collector speculum is 5770 millimeters to the maximum, if with the speculum opening of heat collector again amplification can encounter problems, as shown in Figure 3; Because there is astigmatic effect in natural daylight; Have the inaccurate problem in focusing top if opening is amplified meeting again, sunshine will focus on outside the thermal-collecting tube, thereby cause the thermal-arrest loss.If the opening that does not the increase speculum optically focused of heat collector so is smaller than just, can't obtain higher operating temperature.
The utility model content
The purpose of the utility model is, a kind of slot type heat collector with the secondary condensation device is provided, and it can collect more sunlight, increases the optically focused ratio of heat collector, improves operating temperature, reduces the manufacturing cost of heat collector.
The technical scheme of the utility model: a kind of slot type heat collector with the secondary condensation device; Comprise condenser mirror, reflector bracket, heat collector and collector bracket; Condenser mirror is fixed on the mirror support, and heat collector is fixed on through collector bracket on the focal line of condenser mirror, and the bottom of collector bracket is fixed on the reflector bracket; The two ends of condenser mirror are respectively equipped with the extension condenser mirror, and the top of collector bracket is provided with symmetrically arranged secondary condensation mirror.
In the slot type heat collector of aforesaid band secondary condensation device, condenser mirror all adopts the parabolic type minute surface with the extension condenser mirror.
In the slot type heat collector of aforesaid band secondary condensation device, heat collector adopts vacuum heat collection pipe.
In the slot type heat collector of aforesaid band secondary condensation device, the secondary condensation mirror adopts curved mirror.
In the slot type heat collector of aforesaid band secondary condensation device, the focal line of secondary condensation mirror is on heat collector.The purpose that is provided with like this is in order to guarantee that the sunshine that the secondary condensation mirror is reflected can be radiated on the heat collector.
Compared with prior art, the utility model so just can enlarge the width of condenser mirror owing to the secondary condensation mirror that is provided with symmetrical distribution at the top of collector bracket; The extension solar light irradiation that condenser mirror reflected is on the secondary condensation mirror; Through the secondary condensation mirror with sunlight reflected to heat collector, the thermal-arrest of heat collector ratio will increase like this, thermal-arrest rises than the operating temperature that can make heat collector after increasing; Thereby improve the operating efficiency of separate unit groove type heat collector; After single device efficient improved, the sum of the groove type heat collector of required construction can reduce, thereby made overall cost reduce.
