As mentioned above, desiccant 30 is liquid desiccants, and it can comprise the aqueous solution of 40% lithium chloride.By pump 36 conduit 32 is advanced in desiccant 30 suctions.Before desiccant 30 was introduced collecting chamber 20, pump 36 suction dried agent 30 were by first heat interchanger 38.By cool drying agent 30, desiccant 30 is removed water from first air-flow 28 ability has strengthened.A kind of liquid such as refrigerating medium, by conduit 40,42, flows through heat interchanger 38.In heat interchanger 38, desiccant 30 is cooled to the temperature that is lower than first air-flow 28.Like this, when flowing through collecting chamber 20, first air-flow 28 is cooled.As the alternative of heat interchanger 38, a heat interchanger can be placed on the inside of collecting chamber 20, so that directly cool off first air-flow 28, or cool drying agent 30 after desiccant 30 sprays collecting chamber 20.
The same with collecting chamber 20, regeneration room 22 also comprises pump 56, is used for desiccant 30 is advanced in the regeneration room 22 by conduit 58 suction.Desiccant 30 sprays into regeneration room 22 with the orientation of at least a portion of being substantially perpendicular to second air-flow 48.This layout to collecting chamber 20 is similar.By desiccant 30 and airflow direction between first, second air- flow 28,48 are intersected, increased contacting between air and the desiccant, and do not produced the high pressure that may be associated with concurrent flow.
As shown in Figure 2, pump 56 suction dried agent 30 are by second heat interchanger 60.Any heat of thermal source that makes things convenient for can be added on the heat interchanger 60 by conduit 62,64.Desiccant 30 is heated to above the temperature of second air-flow 48 by the heat interchanger 60 of flowing through, and therefore is heated when second air-flow 48 passes through regeneration room 22.By heating second air-flow 48, more water advances second air-flow 48 from desiccant 30 evaporations.As being positioned at the alternative that heat outside the regeneration room 22 adds parallel operation 60, a heat interchanger 66 can be shown as phantom among Fig. 2, be arranged on the inside of regeneration room 22.Can supply with from any heat that makes things convenient for thermal source via conduit 68,70 heat exchanger 66.
In an alternate embodiments, use non-liquid desiccant with various configurations.In one embodiment, use a kind of solid-state absorbent material to absorb water from introduce air-flow, then this solid-state absorbent material experiences a dry gas stream, and this causes that water vapour transfers in the dry gas stream from this solid-state absorbent material.The transfer of water vapour can occur in the air-flow of a series of alternate cycles, and each described air-flow all will be heated or cooled, and this depends on which can make water vapour shift better.In another embodiment, desiccants is scattered the air collector (air trap) that into contacts with the introducing air-flow.Water in desiccants absorption or the absorbed air.Then, make air collector contact heating element, thereby cause water from desiccant, to be evaporated and make desiccant regeneration.Then, as described below, the air exposure that will include evaporation water is extracted the stage in water.
The humid air fabrication stage 12 produces two air-flows that withdraw from the separation of chamber 20,22.First air-flow 28 that is dry air now withdraws from collecting chamber 20 by exporting 26, is that second air-flow 48 of humid air withdraws from regeneration room 22 by exporting 46 now.The water extraction stage 14 comprises system heat exchanger 72.In embodiment as shown in Figure 2, heat interchanger 72 is configured to hold dry and cold air-flow 28 and damp-heat air 48, makes heat transmit between two air-flows 28,48.Especially, heat can cause water 74 to extract from second air-flow 48 from being delivered to than cold airflow 28 than thermal current 48.As alternative, can with another cooling source,, carry via conduit 76,78 through over-heat-exchanger 72 such as refrigerating medium with first air-flow, 28 coolings, second air-flow 48.
One skilled in the art will understand that water is extracted the latent heat that has increased desiccant 30 from first air-flow 28, and caused the latent heat cooling (latent cooling) of first air-flow 28.In addition because desiccant 30 (or replacedly, chamber 20, perhaps both) be cooled, first air-flow 28 itself has also experienced the sensible heat cooling that reduces self temperature levels, thereby has produced the dry air of cooling.In one embodiment, the present invention utilizes 10 liters of lithium chloride solutions, extracts per hour 2 liters moisture from introduce air, and described introducing air is supplied with 250 cubic metres speed per hour by blast fan.The result has produced the sensible heat cooling capacity of 0.7kW and the latent heat cooling capacity of 1.4kW, therefore makes air themperature descend 8.4 ℃.
As shown in Figure 3, first air-flow 28 and second air-flow 48 are sucked by heat interchanger 72 (respectively by chamber 20,22) by fan 80.Heat interchanger 72 is heat radiating type heat interchangers, and it comprises a plurality of air hoses 82, and air-flow 48 is by a plurality of air hoses 82.When heat when air-flow 48 is delivered to air-flow 28, water 74 is evaporated from air-flow 48 and drips to house steward 84 downwards.Water 74 is opened float valves 86, and float valve 86 is configured to by it self buoyancy or sensing element work.After float valve 86 discharged water 74, then 74 in water advanced condensate collector 88.
In case water extracts from air-flow 48 and collected by condensate collector 88, water will experience a plurality of filtrations, purification, storage and allocation step.As shown in Figure 3, leave the water of heat interchanger 72 and then handle by treatment subsystem 89 in water purification and filtration stage 16, and by water dispenser stages 18 distribution.This in latter two stage 16,18 additional step of practical application depend on application type and the character of using water production system 10.For example, in one embodiment, water purifies and filtration stage 16 uses ceramic filter to remove water-borne pathogens.In addition, available high-grade silver activates charcoal and fills ceramic filter.
Only as exemplary rather than restrictive, the active carbon that obtains easily that can use multiple grade is as medium, such as Columbia, and Pittsburgh, Bamebey-Cheney, Continental, Bone Char, Acticarbone, Cochranex, Carboraffin etc.Such carbon can be by the preparation of multiple source, such as timber, bone, blood, carbohydrate, coal, coconut husk, corncob and cereal stalk, marine alga, brown coal, shuck, oil shale, petroleum coke, rubber scrap and sawdust.Can use active carbon in a variety of forms, such as, can be form granular, pulverous or the ball shape, or combine, such as fiber, mud, paper or other Supporting Media with the material that is prefabricated into.Because high adsorption rate, granulated carbon may be effective especially.Size of mesh opening less than about 100 (mesh size) may be more effective than bigger size of mesh opening, but bigger size of mesh opening may be suitable for the place of the high flow rate of needs.
Still in another alternative embodiments, working power demote continuously (kineticdegradaion fluxion, KDF) and the strainer of carbon combination.This is similar with the granular active carbon strainer with additional metal removal ability, comprises and removes lead.Chlorine is partly changed into chloride by KDF, i.e. zinc/copper synthetic.This has prolonged the media bed life-span of carbon.Such filtration also helps biologically active is dropped to minimum.In addition and/or alternative, the present invention uses reverse osmosis, ion-exchange demineraliting and/or ultra-fine membrane filter either alone or in combination.
Another embodiment of the invention utilizes fabric filter, and it has the ability of removing pollutant from liquid of enhancing.Can utilize inorganic hydrolysis synthetic,, handle employed fabric filter such as NaOH.This filtration system of cellulose acetate fibre strainer of utilizing can be removed microorganism species effectively.By utilizing this system in conjunction with virus filtration unit and reverse osmosis film, but this liquid of high purification such as water.Use inorganic sodium, comprise hydrolysis synthetic (inorganicsodium containing hydrolyzing composition), handle the medium that is used for viral adsorption such as active carbon etc.
Yet it is optimal using the filtration system that is easy to safeguard, in such filtration system, strainer can be regenerated, and does not need frequent replacing strainer.In addition, many other strainers be can use in the different phase of processing procedure, UV strainer, deposition filter, carbon front filter (pre-carbon filter), carbon after-filter (post-carbon filter) and ultrafiltration tube (ultrafiltration cartridges) comprised.
Get back to Fig. 3 now, an embodiment of the invention comprise UV unit 90.Can be effectively UV unit 90 be combined with a plurality of other strainers and use to improve the quality of water.UV unit 90 so designs so that the maximization of the bactericidal effect of the optimum frequency of ultraviolet radiation.Therefore, the inner surface of UV unit 90 scribbles reflecting material, and UV unit 90 be formed in high density, short wavelength ultravioletlamp (not shown) around condense to the best region that can destroy bacterium so that can guiding liquids.Can cover 92 by mobile unit and change ultraviolet lamp.
