Abstract
The utility model discloses a water curtain heat collecting and releasing device, which is particularly suitable for greenhouses. The water curtain heat collecting and releasing device comprises a water curtain, a water inlet pipe, a water return pipe, a water pump and a heat insulation water tank, wherein the water curtain comprises a heat absorption layer and a transparent layer. The heat collecting and releasing process is as follows: the water pump is started during the day, cold water in the heat insulation water tank is conveyed to the water inlet pipe at the upper end of the water curtain, water flowing out of the water inlet pipe flows by the water curtain and can absorb solar radiation to increase water temperature, the water with increased temperature flows into the heat insulation water tank through the water return pipe, and the operation is circulated in such a way, so that the temperature of the water in the heat insulation water tank can be increased constantly for realizing heat collection. A circulating path of water at night is also like this, and when the water flows by the water curtain, heat is released for increasing the environmental temperature and thus heat release is further realized.
Description
Affiliated technical field
The utility model belongs to the agricultural engineering technology field, is specifically related to a kind of water curtain collection heat-releasing device that is applicable to the greenhouse.
Background technology
The maximum characteristics of greenhouse by solar heat are that energy is almost all from solar radiation.Daytime, solar radiation behind the greenhouse, promptly with the stored in form of heat in body of wall and soil; At night, when indoor air temperature descended, the heat of accumulating in body of wall and the soil was again continuously to the greenhouse supply.This exothermic process that holds is a kind of passive mode that depends on greenhouse structure.Want to increase the winter greenhouse temperature at night, then need increase the amount of stored heat in greenhouse, reduce heat loss.
The utility model content
The purpose of the utility model is to propose a kind of water curtain collection heat-releasing device, is particularly useful for the greenhouse, is media with water, as much as possible the heat that solar radiation produced on greenhouse daytime is accumulated, and is used for making night the greenhouse to heat up.
In order to realize the purpose of the utility model, adopt following technical scheme:
A kind of water curtain collection heat-releasing device comprises water curtain, water inlet pipe, return pipe, water pump and attemperater, and wherein the water curtain upper end is installed into water pipe, and return pipe is installed in the lower end, attemperater one end polyphone water pump and water inlet pipe, and the other end connects return pipe; Said water curtain comprises a heat-sink shell and a hyaline layer; On the said water inlet pipe scupper is arranged.
The heat-sink shell of said water curtain is the black plastic film, and hyaline layer is an overlay.
Said water curtain right ends sealing.
Said water inlet pipe endcapped.
Said scupper is poroid or slot-shaped.
It is underground that said attemperater is embedded in the greenhouse, is provided with heat-insulation layer all around.
Be provided with water leg between said water curtain and the return pipe;
Said water leg is semicircle pipe fitting.
Between said water pump and the water inlet pipe control valve is installed.
Compared with prior art, the advantage of the utility model is:
, do not heat winter and can produce any pollution as thermal source with solar energy; , with low cost with water as heat storage medium; The hot water of being accumulated also can be used as irrigation water, increases the crop root zone temperature.
Description of drawings
Fig. 1 is the water curtain collection heat-releasing device forward sketch map of the utility model embodiment;
Fig. 2 is the water curtain collection heat-releasing device side schematic view of the utility model embodiment.
Wherein: 1. attemperater; 2. return pipe; 3. wall after; 4. water inlet pipe; 5. water curtain; 6. water leg; 7. water pump; 8. control valve; 9. film-clamping groove; 10. overlay; 11. black plastic film; 12. bracing frame.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
Present embodiment is used this water curtain collection heat-releasing device in greenhouse by solar heat.The long 20m of the greenhouse by solar heat that is adopted, wide 8m, height overall 3.8m, water curtain collection heat-releasing device are shown in accompanying drawing, and wherein Fig. 1 is the forward sketch map, and Fig. 2 is a side schematic view.Water curtain 5 long 19m, high 2.5m, its heat-sink shell are black plastic film 11, are processed by the PE material, are used for absorbing solar radiant heat, hyaline layer is an overlay 10, is used for preventing the evaporation of water seepage; Two membranes is fixed on the wall 3 of back through film-clamping groove 9.Water inlet pipe 4 diameters are 32mm, are contained in inboard, water curtain 5 upper ends, are fixed on the film-clamping groove 9 with iron wire, and it is the pore of 3mm that the scupper on the pipe adopts diameter.Water leg 6 is the semicircle pvc pipe spare of diameter 110mm, is fixed on the ground, greenhouse through bracing frame 12.Water curtain 5 lower ending openings also hang in water leg 6, and right ends is taked encapsulation process.Attemperater 1 long 4m, wide 1m, high 1m is processed by the PVC material, and it is underground to be embedded in the greenhouse, handles with polyphenyl plate heat preserving all around; Attemperater 1 one ends and water pump 7, control valve 8, water inlet pipe 4 polyphones, the other end and return pipe 2 and water leg 6 polyphones.
The collection exothermic process is: open water pump 7 daytime, make cold water in the attemperater 1 flow to the water inlet pipe 4 of water curtain 5 upper ends, and the pore from water inlet pipe 4 flows out; Flow to black plastic film 11 equably, absorb solar radiation water temperature is raise, overlay 10 can prevent the evaporation of water seepage; Current after the intensification advance water leg 6, are back to attemperater 1 through return pipe 2 again, so move in circles; The water of 1 li of attemperater is constantly heated up, realize the collection of heat.Night, the circulating path of water also was so, just when flowing through black plastic film 11, emits heat the greenhouse is heated up, and realized the release of heat.
In the above-described embodiments, in the water curtain lower end one water leg is set, the water curtain lower ending opening also hangs in water leg, to collect the water that flows out from water curtain.But also can not adopt this mode,, reserve one or more openings as the water curtain lower end is not exclusively sealed, opening shape and return pipe coupling, thus these one or more openings are directly linked to each other with one or more return pipes, also can realize collection to water.In the above-described embodiments, the scupper on the water inlet pipe is a circular hole, but also can adopt other shape, like the hole of other shapes such as square hole, slot-shaped etc.In the above-described embodiments, the heat absorption internal layer material therefor of water curtain is a black PE plastic foil, but also can adopt other heat absorption capacities such as aluminium-plastic panel, black nonwoven material preferably.In the above-described embodiments, the water curtain collection heat-releasing device of the utility model is applied to greenhouse by solar heat, but is not limited to this scope of application.
