Further, described water-locator is a pipe with uniform small pores or an arc groove.
Tool of the present invention has the following advantages: the front water circulation heat exchange pattern that 1, adopts original creation, under this pattern, water circulation resistance is little, intensity of circulation is large, the pump head that need to use and power of motor are all smaller, and the sunlight heat that absorber plate is inhaled collection has 90% can be absorbed and take away by water exchange, when cycle heat exchange, water is to be exposed to airbornely, and this can also play to water the effect of purification, freshization, activation; 2, absorber plate is that simple a painting is brushed with high selectivity heat-absorbing paint, and the surface plate that angle of inclination is α, it can directly add brush high selectivity heat-absorbing paint with smooth roof boarding and substitute, and the integrated absorber plate of large area also can directly be used as the roofing element of new building, dual-use material, this can significantly reduce the cost of front water circulation heat exchange solar heating engineering; 3, because heat exchange place water circulation resistance is little, intensity of circulation is large, make absorber plate always be in temperature moves at 36 ℃, also with light-passing plastic insulation film made, cover the top of the absorber plate circulation water surface simultaneously, thereby the minute surface that suppresses water is reflective, convection heat losses and the evaporation of water heat loss of minimizing air, guarantees that system thermal efficiency reaches more than 50%.
Accompanying drawing explanation
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of water circulation heat exchange solar heating engineering system before the present invention.
Fig. 2 is that Fig. 1 part-structure is along the cutaway view of A-A direction.
The specific embodiment
Please refer to shown in Fig. 1 to Fig. 2, water circulation heat exchange solar heating engineering system before the present invention, this system comprises millpond 1, slightly considers net 2, circulating pump 3, water-locator 4, absorber plate 5, water leg 6, fine filter 7, light-passing plastic insulation film 9 and foam thermal insulation backboard 10, described millpond 1 connects described thick worry net 2 (for water is tentatively filtered) by the first pipeline 81, this thick worry net 2 connects described circulating pump 3 by second pipe 82 again, and this circulating pump 3 is for being raised to the water extraction of described millpond 1 in described water-locator 4; Described circulating pump 3 is connected with described water-locator 4 by the 3rd pipeline 83, and this water-locator 4 is positioned at the top of described absorber plate 5 high-end water inlets place; Described absorber plate 5 is positioned at the position of eminence illumination abundance, this absorber plate 5 is for being coated with the surface plate that is brushed with high selectivity heat-absorbing paint, or be coated with the roof boarding be brushed with high selectivity heat-absorbing paint, wherein said surface plate or roof boarding all tilt an angle [alpha] and 3 °≤α≤45 °.Described water leg 6 is positioned at the below of described absorber plate 5 low side water outlets place, for collecting the water that flows through absorber plate 5, and this water leg 6 is also connected with described fine filter 7 (comparatively comprehensively filtering for the water to after heat exchange) by the 4th pipeline 84, this fine filter 7 is connected with described millpond 1 by the 5th pipeline 85 again.Wherein, described water-locator 4 is a pipe with uniform small pores or an arc groove; Described millpond 1 is swimming pool or the aquatic products culturing pool of surviving the winter.
Described light-passing plastic insulation film 9 is covered in the top of the described absorber plate 5 circulation waters surface, for suppressing convection heat losses and the evaporation of water heat loss that the minute surface of water is reflective, reduce air; Described foam thermal insulation backboard 10 pads are in the lower surface of described absorber plate 5, for reducing scattering and disappearing of absorber plate 5 heats.Certainly, when running into continuous rainfall sky, in order to keep the temperature of water in millpond 1, we also need additionally to take artificial heat insulation measure, and this is applied often in the prior art, just seldom introduce here; , in order to prevent excessive rainfall, flow in millpond 1 meanwhile, make the water overfill of millpond 1, we can be near arranging a switch on the pipeline of water leg 6, be used for control piper connection or close.
This system water circulation theory is as follows: under the effect of circulating pump 3, the water of millpond 1 flow to water-locator 4 through thick worry net 2 and circulating pump 3; Water-locator 4 can by water equably cloth be sprinkled upon high-end water inlet place of absorber plate 5, the water that enters absorber plate 5 can be pooled to after the plate face of flowing through that in water leg 6, (both sides at absorber plate 5 are provided with baffle plate, for anti-sealing, flow away from the side), and water, in the plate face of flowing through, also can be inhaled the heat collecting by absorption band limp face; The water that is pooled to water leg 6 can flow back to millpond 1 again after the filtration through fine filter 7, a complete cyclic process that Here it is.When reality is used, this system is by the above complete process that constantly circulates, and this not only can play the effect of Automatic-heating warm-keeping to the water of millpond 1, can also reach water purification, freshization, activation.
Before the present invention, water circulation heat exchange solar heating engineering system has the following advantages:
1, the front water circulation heat exchange pattern of the novel original creation of employing, so-called front water circulation heat exchange, refers to that heat-exchange working medium (mainly refer to water here) carries out the mobile heat exchange of planar transfer at the upper surface of meeting light absorber plate.Under this pattern, water circulation resistance is little, intensity of circulation is large, and the pump head that need to use and power of motor are all smaller, and the sunlight heat of absorber plate suction collection has 90% can be absorbed and take away by water exchange; Simultaneously water can also directly be subject to solar ultraviolet and irradiates and play sterilization effect, and water is directly exposed in air, and this is not only conducive to deodorizing, and freshization water quality also helps the dissolving of oxygen, thereby reaches the object of activated water.
2, absorber plate is that simple a painting is brushed with high selectivity heat-absorbing paint, and the surface plate that angle of inclination is α, it can directly add brush high selectivity heat-absorbing paint with smooth roof boarding and substitute, and the integrated absorber plate of large area also can directly be used as the roofing element of new building, dual-use material, this can significantly reduce the cost of front water circulation heat exchange solar heating engineering.
3, because heat exchange place water circulation resistance is little, intensity of circulation is large, make absorber plate always be in temperature moves at 36 ℃, also with light-passing plastic insulation film made, cover the top of the absorber plate circulation water surface simultaneously, thereby the minute surface that suppresses water is reflective, convection heat losses and the evaporation of water heat loss of minimizing air, guarantees that system thermal efficiency reaches more than 50%.
Although more than described the specific embodiment of the present invention; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present invention; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present invention, all should be encompassed in the scope that claim of the present invention protects.
