Description
The utility model relates to the technical field of obtaining of fresh water.
The overwhelming majority of earth surface is covered by ocean and desert, and human activity in these two areas is along with the development of society is more and more important.But,, guarantee that water supply is picking out earlier of its all activities for people in ocean and desert area activity.This is so for the resident in those islands and desert not only, and is engaged in the people of frequent day by day oil development, communications and transportation, military activity and scientific exploration for those, and is all the more so.Like this, how to obtain fresh water, just become human common concern in ocean and desert area, and the problem of still needing and solving.
The purpose of this utility model be to provide a kind of can be in the ocean, the area of desert and other lack of water, utilize wind energy and solar energy as power, and from air, obtain the device for fetching water from air of fresh water.
Tellurian water is with vapour, liquid, solid ternary and deposit, because the effect of terrestrial gravitation and solar radiant heat, the migration and ternary conversion of causing water on the earth; This has just caused atmosphere to become the terminal of water circulation forever.According to the conservation of mass of the water yield, along with the rising of air themperature, when surface water capacity reduced because of evaporation, airborne absolute moisture content was but increasing; Therefore, under the situation that does not have face of land water source of fresh water, air has just become us to obtain the source of fresh water.Airborne water vapour is become water, is exactly basic design of the present utility model.The utility model comprises water fetching device and Salar light-gathering cover.Water fetching device is placed on the support above the Salar light-gathering cover.Said water fetching device is made of diffuser, the adsorbent bed that is placed with adsorbent, phase-change thermal storage condenser, shading guide vane, vacuum flask, shell, support and water intaking pipeline etc.Support is fixed on outer casing inner wall, supports adsorbent bed and vacuum flask, and the adsorbent bed lower end is connected with the shading guide vane, and the phase-change thermal storage condenser is placed in the lid of vacuum flask, and diffuser covers on the shell.At night, especially desert area, temperature is lower, and relative humidity is higher; At this moment, take off diffuser, utilize natural wind that adsorbent bed is adsorbed airborne water vapour; To daytime, with also sealing on the diffuser cover, utilize the solar energy heating adsorbent bed, make the water vapour desorption; Water vapour behind the desorption carries out the natural convection circulation with air in diffuser; When the water vapour contact is lower than the phase-change thermal storage condenser surface of dewpoint temperature, just condense thereon, become water droplet and flow into vacuum flask.
Flow into vacuum flask for the ease of water droplet, the inner surface of phase-change thermal storage condenser is done funneling.In order to prevent the water evaporates in the vacuum flask and the cold insulation of phase-change thermal storage condenser, the lid of vacuum flask is made with thermal insulation material.The available convex lens of Salar light-gathering cover replace.Thereby the utility model also can comprise Salar light-gathering tracking system and or the mechanical system of control water fetching device lifting carrying out desorption heat scan.
The used adsorbent of the utility model can select that silica gel, zeolite etc. are various to have than high absorption property and nontoxic material for use.Adsorbent bed is the container made from wire lath.Phase-change material in the phase-change thermal storage condenser is selected the bigger material of latent heat of phase change for use, and its freezing point is near locality average temperature round the clock.For satisfying different regions and requirements of different seasons, every device for fetching water from air can prepare two to three phase-change thermal storage condensers of being filled and presented by different phase-change materials.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1, device for fetching water from air schematic diagram.Wherein, 1-water fetching device, 2-Salar light-gathering cover, 3, the 4-support.
The moisture equilibrium at dry side figure of accompanying drawing 3, various adsorbents.
Isobaric adsorption curve figure when accompanying drawing 4, silica gel absorption water.
Referring to accompanying drawing, obtain solar energy as much as possible in order to make adsorbent bed 7, adopt transmitance to solar radiation near 1, and low temperature long-wave radiation transmitance is made diffuser 5 near 0 quartz glass.Adsorbent bed 7 is central column containers of being made by wire gauze, in put particle silica gel adsorbent 6.The shell of vacuum flask lid 11 is made of plastics, in fill out expanded perlite, there is a groove middle and upper part of lid 11, bottom land has an aperture; Make shell by stainless steel, in fill out phase-change material phase-change thermal storage condenser 10 be placed in the groove, its funnel aperture is corresponding with the bottom land aperture.Shell 13 is the canister of outer plating polished aluminum film.Metallic support 8 rivetings on the inwall of shell 13, on prop up adsorbent bed 7, subiculum vacuum flask 12.In order to make silica gel absorber reach the required high temperature more than 150 ℃ of water desorption, adopt paraboloidal solar light-condensing cover 2, and make the optically focused focus be positioned at adsorbent bed 7.Utilize shading guide vane 9 to keep the sun off, make phase-change thermal storage condenser 10 cold insulations; And make the flow through surface of phase-change thermal storage condenser 10 of water vapour, thereby constantly condensation.
Because the effect of wind speed, adsorbent bed ceaselessly carries out the wet exchange of heat with a large amount of air at All Through The Night; Therefore, though the water capacity in every cubic metres of air is not very high,, be enough to make adsorbent to be in saturation state through the absorption at a night.Still be the area, ocean in the desert no matter, the temperature of night air is lower, thereby relative humidity is higher, concerning based on the adsorption process of the device for fetching water from air of temperature difference absorption principle, is very favorable like this.10Kg silica gel is housed in adsorbent bed, and the relative humidity of night air is 60%, and can find its water absorption rate from accompanying drawing 3 is 30%; So when saturated, the water absorption of this adsorbent bed is 3Kg.
For silica gel absorber, water desorption is temperature required to be 150 ℃～200 ℃, and solar constant is 1KW/m
2So the solar energy that absorbed daytime is enough to satisfy the requirement of desorption institute calorific requirement.Because adsorbent bed is the central column container, the caloric receptivity of its external surface is much larger than inner surface, thereby makes outside air get the hot inside that is higher than; Produce density contrast thus and as power, cover interior humid air when making regeneration constantly from the rising of adsorbent bed space outerpace, descend in the inner space, the natural convection that forms air circulates.Because during regeneration, water fetching device seals, the continuous desorption of moisture content has caused the confined space absolute moisture content to rise suddenly, and corresponding dewpoint temperature is greatly improved; Therefore as long as the surface temperature of phase-change thermal storage condenser is lower than the dewpoint temperature of air in the confined space, then airborne moisture content will constantly condense thereon, and enters vacuum flask at action of gravity lower edge funnel.When desorption temperature was 150 ℃, by accompanying drawing 4 as seen, the saturated moisture content adsorbance of silica gel was about 5%; This moment, the water content of this adsorbent bed was 0.5kg, so the water withdrawal of device for fetching water from air is 2.5kg.Need to prove: if night, wind speed was lower, perhaps because sorbing material is relatively poor, make that adsorbance does not reach capacity after the All Through The Night, then water withdrawal will decrease.If silica gel is in the adsorbance of All Through The Night 50% of the adsorbance that only reaches capacity, then above-mentioned filling out towards the device for fetching water from air of 10Kg silica gel will be 1Kg at a water withdrawal round the clock, rather than 2.5Kg.In the desert, Africa in summer of drying, fill out 10H in can adopting
