Background technique
Potential energy, wind energy and the solar energy of clean energy resource such as water, have been obtained extensive utilization.For western China Population is few, and the sunshine-duration is long, and the feature more than unoccupied place is generated electricity, construction cost is low, has using solar heat air-flow Wide application prospect.
During thermal current chimney generation, influence its generating efficiency have collection heated ceiling exterior surface, chimney inner surface, The three parts dust of thermal-arrest external surface.Wherein, the dust for collecting heated ceiling exterior surface is suspension settlement etc. since dust storm is brought into Factor causes, and the dust of chimney inner surface, thermal-arrest external surface then due to the air-flow of power generation by thermal-arrest ceiling lid below Air duct enters, and the dust of substantial amounts has been brought into, in order to guarantee the flow velocity of gas, the air intake vent of solar energy thermal current electric generating apparatus Area is often smaller, and in order to improve generated output, and the area needs of heat collector surface design bigger, and adds west area Dry, dust storm is larger, and factors above can directly result in heat collector surface and be covered by dust or dust storm.Due to being covered on thermal-arrest canopy The dust refractive index of top cover and thermal-arrest external surface is high, and particle size is big, will cause reflection/scattering process of light, directly affects Absorption of the heat collector surface to light, causes gas flow temperature not high enough, the impacted problem of generating efficiency.And the attachment of chimney inner surface Dust the problems such as it will cause line cloggings, simultaneously as tunnel inlet area is small and thermal-arrest canopy area is big, manually to heat collection body And the cleaning of pipeline internal dust is difficult, therefore, how inexpensive, efficient processing air-flow dirt problems are that outdoor is answered With the problem of thermal current chimney generation.
Summary of the invention
The purpose of the present invention is to provide one kind to have dust-proof, self-cleaning solar heat air-flow chimney generator, with Solve the problems, such as that power generator generating efficiency mentioned above in the background art is low, manual cleaning difficulty is big.
To achieve the above object, the invention provides the following technical scheme: a kind of have dust-proof, self-cleaning solar energy hot gas Chimney generator, including chimney, generator and heat collection body are flowed, the two sides at the top of the heat collection body are equipped with thermal-arrest ceiling lid, Chimney is fixed between two thermal-arrest ceiling lids, the side interlocking of the chimney bottom has arc mounting plate, the arc The side of shape mounting plate is equipped with generator by a pair of of connecting rod, the top sum aggregate of the inner wall of the chimney, thermal-arrest ceiling lid The top of hot body is paved micro-nano array film.
As a preferred technical solution of the present invention, the arc mounting plate is fixed with reinforcement at the top of the other side Plate, the arc mounting plate are fixed with handle in the middle part of the other side.
As a preferred technical solution of the present invention, the heat collection body be the stone of black or dyeing, sandy soil, pitch, Paint, selective coating, and the angle that the heat collection body and ground are formed is 3 ° -80 °.
As a preferred technical solution of the present invention, the thermal-arrest ceiling lid is made of glass material.
As a preferred technical solution of the present invention, the micro-nano array film is micro-nano array structure, described The dimension of picture of micro-nano array structure and period, graphics shape was cylinder, circular cone, frustum, cuboid, more at 20nm-400 μm Face body, the arrangement mode of the micro-nano array structure are that cubic close is accumulated or six sides are tightly packed.
Compared with prior art, the beneficial effects of the present invention are: the present invention is a kind of to have dust-proof, self-cleaning solar heat Air-flow chimney generator, the micro-nano array film of inner wall of stack, so that dust is not easy to be adhered to chimney inner surface, so that cigarette Chimney is not easy to plug;The micro-nano array film at thermal-arrest ceiling caping end, enables light that can completely inject inside heat collection body, and It can reduce manually to the frequency of thermal-arrest canopy cleaning, reduce the attachment of dust;The micro-nano array film on heat collection body top, makes to collect Hot physical efficiency preferably absorbs sunlight, and since heat collection body takes tilting paved, tunnel inlet has air entrance, and dust will In heat collection body most external, easy cleaning;When micro-nano array structure size is in sub-wavelength range, due to diffraction and interference effect It answers, the absorption to light can be obviously increased when the incidence angle of light increases, and then promote generating efficiency;The interlocking of chimney bottom side Arc mounting plate can be convenient the fast quick-detach of generator under the use of cooperation stiffening plate and handle, be convenient for periodic maintenance.
