Abstract

A preparation device for household solar pure water is manufactured based on horizontal integral-type plate solar water heater, which mainly consists of a support frame (1), a heat preservation water tank (2), a cover plate (3), a condensation plate (4), an elastic capsule (5), an upper water catch groove (6), a lower water catch groove (7), a water catch basin (8), a water diversion tube (9), a drag ring (10), a sunshade cover (11), a fan (12), as well as a water absorption plate (13). After the water content in the heat preservation water tank (2) is evaporated, the high-temperature water vapor is condensed on the condensation plate (4) and the cover plate (3) to become the pure water and is separately flown into the water catch basin (8) and the water catch grooves, and is finally flown out through the water diversion tube (9). The elastic capsule (5) can make the device inner space form a certain negative pressure, which is favor of water content evaporation in the heat preservation water tank (2). The utility model has simple structure, which is easy to be completed and is convenient for requirements for people's family life.

Description

Domestic solar pure water preparation facilities

Technical field

The present invention relates to the pure water preparation facilities, specifically be a kind of utilize to condense after the solar heating moisture evaporation form the device of pure water.

Background technology

Along with China's industrial expansion, more and more serious to phreatic pollution, underground water no longer is fit to directly drink, so people are increasing to the demand of purified drinking water.Produce pure water at present and adopt methods such as precipitation, filtration, reverse osmosis, ion-exchange, electrodialysis mostly, the equipment complexity, investment is big, and easy-maintaining and energy consumption are not big.Therefore the price of pure water is also higher relatively, and drinking pure water for the geographic people of relative poverty also is a very big burden.

Summary of the invention

In order to address the above problem, the present invention proposes a kind of domestic solar pure water preparation facilities, and is simple in structure, is easy to make, and cost is low.

The technical solution adopted in the present invention is as follows: this domestic solar pure water preparation facilities is to be made on the basis of the closing-sunning type flat plate solar water heater of horizontal positioned, comprise bracing frame, attemperater, cover plate and aqueduct composition, attemperater is installed on the bracing frame, cover plate snugly fits into the top of attemperater, described attemperater profile is a rectangular parallelepiped, and the top of cover plate has centre hole; The cold plate that has refrigeration source is installed between cover plate and the attemperater, and the upper limb of cold plate is connected on the centre hole of cover plate, and the lower rim of cold plate is connected on the inwall of attemperater; Poly tank and following poly tank are installed on the cover plate, and the bottom of cold plate is equipped with catch basin, and the pure water that is formed by steam coagulation on cover plate and the cold plate is pooled to poly tank and catch basin respectively, finally flows out by aqueduct.

One side of described cover plate lower end has circular hole, an end opening of elastic capsule and with the same diameter of above-mentioned circular hole and combine closely; The other end is stretched the inside at cover plate, seals and has a draw ring.

1. bracing frames among the figure, 2. attemperater, 3. cover plate, 4. cold plate, 5. elastic capsule is 6. gone up poly tank, 7. descends poly tank, 8. catch basin, 9. aqueduct, 10. draw ring, 11. sun shades, 12. fans, 13. water sucting plates.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Figure 1 shows that a preferred embodiment of the present invention.As shown in Figure 1, these family expenses sun power pure water preparation facilities is mainly by bracing frame 1, attemperater 2, cover plate 3, cold plate 4, elastic capsule 5, last poly tank 6, following poly tank 7, catch basin 8, aqueduct 9, draw ring 10, sun shade 11, fan 12 and water sucting plate 13 are formed.

Attemperater 2 is an annular, is installed on the bracing frame 1, has inlayed water sucting plate 13 on its inwall.Water sucting plate adopts exotic materials to be made, and it can make the raw water molecule be the dispersion unbound state, helps moisture evaporation.Cover plate 3 is installed in the top of attemperater 2, and profile is that two prismoids stack and form, and its upper end has centre hole.Cold plate 4 is a drum shape, and it is placed on the internal ring wall of attemperater by the centre hole of cover plate, thereby forms a sealed space together with cover plate 3, attemperater 2.The cross section of cold plate 4 is processed into bent circular, can increase its working area like this under the fixed height, and the cold plate intermediary is hollow to be to pass water-heater, and the upper space environment is communicated with ground, helps the work of fan 12.

Catch basin 8 is installed in cold plate 4 bottoms, is enclosed within on the cold plate tightly.Poly tank 6 and following poly tank 7 are installed on the inwall of cover plate 3, when there is wind in the space of Working environment, can take heat on the glass cover-plate, make it remain on the ambient air temperature state, have a large amount of water vapor aggegations like this on glass cover-plate, and poly tank can reclaim these pure water return by aqueduct and flow to 8 li of catch basins.

Also have two circular holes on one side of the inwall of cover plate 3, an elastic capsule 5 has been installed on each circular hole.In order to improve the output of pure water, this device has adopted raw water to be in the device sealing and to have under the state of a negative pressure and evaporate.Negative pressure is to produce like this: open two circular holes on the glass cover-plate 3 of the both sides, lower end of cold plate, and be provided with elastic capsule 5, the one end is the same bore of opening and above said round hole, and combines hermetically.The other end seals, and just as piston cap, and having draw ring 10, the width of its length and water-heater is very nearly the same.The volume of supposing water-heater is V1, and two elastic capsule volumes are V2 altogether, before device seals V2 is placed in the middle of the V1, makes the full expansion of V2, seals this device then.If air normal pressure lower density is d, the interior actual Air quality of being sealed of water-heater this moment is (V1-V2) * d.We hang a weight by a fixed pulley on draw ring, an end of capsule sealing will move to opening end, stop can to form in the device of back the negative pressure of a high water column of h, and this negative pressure helps evaporation of water.Pressure increase when water vapour neutralizes mutually with the negative pressure of above-mentioned generation, and weight can continue to spur piston and move outward, keeps this negative pressure.When running balance, suppose that at this moment piston cap drives to terminal point.This moment, the volume of device was V1, and still (V1-V2) * d of Air quality wherein.Apparent air wants thinner, and water vapour content increases, favourable atomizing.Also can produce negative pressure after the atomizing, negative pressure helps evaporation again, so repeatedly, can increase the generation of pure water.At water inlet pipe and water outlet pipe end a U-shaped pipe is set respectively, makes it highly be a bit larger tham h, at this moment when producing negative pressure in the device, the water column that will produce a corresponding size in the U-shaped pipe is poor, and this water column difference has been kept the sealing in the device.The container of containing pure water in the device is big slightly, and when avoiding negative pressure to exist, pure water can not flow back in the raw water and go like this.

Sun shade 11 is installed on the cover plate 3, and fan 12 is hung on the roof of sun shade.When this device used, sun shade can block the sunlight that shines directly on the cold plate, and the refrigeration source that cold plate 4 adopts can be with the water of condensation that slowly flows down, and the fan 12 that is driven by conventional energy resources gets rid of water of condensation on cold plate uniformly.Because the fans drive air circulates fast, favourable condensation evaporation of water, thus make cold plate keep low-temperature condition always, help the formation of pure water.
