Abstract
The invention relates to a solar heat storage and supply facility using black liquid, in particular to a solar heat storage and supply facility for greenhouses. The solar heat storage and supply facility is characterized in that a heat collector is provided outside a greenhouse, a liquid storage tank is disposed within the greenhouse, the heat collector is connected with the liquid storage tank through a circulating pipeline, the heat collector, the liquid storage tank and the circulating pipeline are filled with heat medium which is made from ammonium nitrate, black dye and water, the heat collector is composed of a transparent cover plate, collector tubes, a header, an insulating layer and a housing, the transparent cover plate is made of double-layer glass or double-layer transparent plastic, and the collector tubes and the header are single-layer glass tubes or single-layer transparent plastic tubes. Therefore, the defects of the related prior arts, such as strict requirements on materials, technical complexity and high cost, are overcome. The solar heat storage and supply facility has the advantages of energy efficiency, environment friendliness, practicality and low cost and is widely applicable to various greenhouses.
Description
Technical field
The present invention relates to a kind of Tai Yang Neng ?look liquid store heating facility, especially a kind of solar energy greenhouse booth stores heating facility.
Background technology
In the winter that the north is cold, because the sunshine time is short, intensity of illumination is more weak, although green house has certain heat storing and heat preserving ability, crop normally survives the winter production often to need heat supply to heat to guarantee.At present, supplying heat source is mainly coal, is straw on a small quantity.Though have experimental solar cell and wind energy heat supply, cannot apply in actual production because cost is higher.So the heat supply of green house and energy-conservation, has become one of northern facility agricultural technical barrier urgently to be resolved hurrily.
At present, domestic and international solar powered fluid heat collector, mainly comprises flat plate collector and vacuum tube collector, and its heat-absorbing medium is water.No matter be flat-plate collector or vacuum tube collector, all need on absorber plate or the dark solar energy absorbing coating of vacuum tube inner layer outer surface spraying, to absorb solar radiant energy to greatest extent and to convert thereof into heat energy, and reduce the thermal radiation of heat collector as far as possible.Thus its have that material requirements is strict, complex process and high in cost of production defect.
Summary of the invention
The object of the present invention is to provide a kind of Tai Yang Neng ?look liquid for heat collection device be the facility of green house accumulation of heat and heat supply.
Technical scheme of the present invention completes as follows:
The green house solar energy comprising heat-absorbing medium, heat collector, liquid reserve tank and circulating line stores heating facility, its design feature is: described heat collector is arranged on outside green house, liquid reserve tank is arranged in green house, and heat collector is connected by circulating line with liquid reserve tank; Heat-absorbing medium be filled with heat collector, liquid reserve tank and circulating line Nei ?look liquid.Suo Shu ?look liquid be ammonium nitrate, ?the mixing material of look dyestuff and water.Described heat collector is made up of transparent cover plate, thermal-collecting tube, union pipe, thermal insulation layer and shell, and transparent cover plate is double glazing or Double-layered transparent plastics, and thermal-collecting tube and union pipe are single-glass pipe or single-layer and transparent plastic tube.Described liquid reserve tank is made up of casing and cover plate, and casing is plastic box, and cover plate is glass plate or transparent plastic sheet.
This facility staff principle is: when solar light irradiation heat collector, absorbing medium absorbs heat and temperature raises, solution density in heat collector reduces and rises and enter liquid reserve tank through circulating line, the solution that in liquid reserve tank, density is larger enters heat collector, thus forming heat-absorbing medium in the circulation of facility fro inside, such heat energy is just stored in the solution of liquid reserve tank.Opening the thermal insulation layer of liquid reserve tank during night, is booth heat supply by liquid reserve tank surface radiating.
The invention has the beneficial effects as follows: 1, solar powered fluid heat collector and solar energy greenhouse booth are organically combined, reach and utilize solar powered fluid heat collector to store the object of heat supply for solar energy greenhouse booth; When 2, utilizing ammonium nitrate to dissolve and separate out, there is stronger heat absorption and exothermic character, and the most powerful feature of phase jljl body ?look heat absorptivity, achieve energy-saving and environmental protection, practicality and low cost theory; 3, heat-absorbing medium Wei ?look solution, namely ammonium nitrate, ?the mixed solution of look dyestuff and water, substitute water and have heat absorption and heat storage function concurrently; 4, endothermic tube is single-glass or transparent plastic, does not need to spray solar energy absorbing coating.
