Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
The utility model provides a kind of daylight accumulation of heat underground methane-generating pit, comprise pond body 1 and spherical top board 2, all sides of described top board 2 are one-body molded longitudinal coaming plate 3, form a collecting space 4 between coaming plate 3 and spherical top board 2, be provided with the cover plate 5 of collecting space 4 capping between described coaming plate 3 and top board 2;
Described top board 2 is provided with one deck heat-sink shell, and the top that top board 2 is positioned at vertex is provided with spray header, and described coaming plate 3 arranged outside is disposed with thermal insulation layer 6 and enclosure wall 7.
Top board 2 adopts rot-resistant stainless steel plate to make, long service life, and intensity is guaranteed, global design shape is spherical cap shape, the summit of spherical crown upward, spray header is provided with above summit, spray header is towards top board 2 atomizing of liquids, in the present embodiment, this liquid is water, water flows downward along spherical crown, finally flow in the collecting space 4 of top board 2 weeks sides, because the sun directly shines on top board 2, top board 2 temperature is all higher, flow through in the process of top board 2 at water, water is not had no progeny by heat trnasfer and is gathered daylight heat, temperature rises, after cover plate 5 is covered, collecting space 4 seals, achieve the collection of heat, in order to increase the heat insulation effect of collecting space 4, thermal insulation layer 6 is had in the arranged outside of coaming plate 3, described thermal insulation layer 6 is polyphenyl plate heat preserving layer 6, certainly, in other embodiments, described thermal insulation layer 6 also can adopt other lagging materials, or adopt vacuum layer etc. to realize effective insulation of collecting space 4, thermal insulation layer 6 skin is fixed by fragment of brick.
In the present embodiment, described top board 2 is provided with one deck heat-sink shell, and this layer of heat-sink shell has various structures, such as the mineral wool board etc. of the heat absorption cloth of blackwash layer, black, the plastic layer of black or black, the utility model does not do concrete restriction, absorbs as long as can realize the effective of heat.
Concrete, blackwash layer can adopt electroplated coating, electrochemical surface conversion coating, Vacuum Deposition coating or coating type coating, wherein, electroplated coating can be black chrome coating, black nickel coating or black cobalt coating, electrochemical surface conversion coating can be that (alumilite process coating is a kind of porous-film to alumilite process coating, porosity reaches 22%, and during electrolytic coloring, metal is easily deposited in micropore.Metallic salt for electrolytic coloring has: nickel salt, pink salt, cobalt salt and mantoquita etc., and the performance such as anti-corrosion, wear-resisting and resistance to illumination is also fairly good.), the anodized coating of CuO conversion coating or steel.
By the setting of heat-sink shell, the energy of sunlight can be absorbed fully, promote the temperature of whole top board 2, the temperature of the water flowing through top board 2 is raised rapidly, realize water cycle accumulation of heat, the water after these heating can provide thermal source for methane-generating pit, also outwards can be carried by external pipe, for bathing or cooking, realize effective utilization of the energy.
Because the position of the sun changes always, in the present embodiment, described top board 2 adopts the welding of folding arch, the welding of folding arch refers to that top board 2 is not excessively smooth, but jointly formed by a lot of little knuckles, therefore, solar light irradiation is after top board 2, what produce is diffuse-reflectance, can be the most sufficient by heat collection.
