Description
Technical field
The invention belongs to air water-intaking technical field, particularly a kind ofly can from drier air, extract the method for moisture and realize the water fetching device of the method.
Background technology
Steam in air mainly for outdoor natural air, and is converted into more aqueous water by air water-intaking as much as possible.From air, water intaking is the important channel solving water resource deficiency.
Preparing fresh from air, mainly contains two kinds of methods (referring to paper " progress of air water-intaking technology ", " chemical industry progress ", the 30th volume the 8th phase P1664 ~ 1669 in 2011):
1, cooling water intaking: cooling humid air, makes it reach below dewpoint temperature, condensation water outlet.The method efficiency when air humidity content is large is high, and water withdrawal is large, but when air humidity content hour, along with air dew point temperature reduces, efficiency of producing drinking water sharply declines, and even cannot fetch water.
2, absorption water intaking: utilize the moisture in bibulous solid or liquid drier absorption air, then heating desorption, condensate water steam obtains fresh water.Moisture can be drawn out by these class methods from the very little air of water capacity, but the power consumption of its heating desorption process is large, and process is discontinuous, and at air humidity content hour, efficiency is not high yet.
In a word, prior art Problems existing is: be difficult to continuous from the air of drying, efficient, energy-conservation ground preparing fresh.
Summary of the invention
The object of the present invention is to provide a kind of method of fetching water from dry air and device, can preparing fresh from drier air continuous, efficient, energy-conservationly, meet arid area water demand.
The technical solution realizing the object of the invention is: a kind of method of fetching water from dry air, comprises the steps:
10) moisture enrichment: by continuous adsorption and desorb, becomes low water capacity air into high water capacity air;
20) condensation draining: by high water capacity Air flow to dew point, separates out the moisture in air.
The technical solution realizing another object of the present invention is: a kind of device of fetching water from dry air, comprises desiccant wheel and surface cooler, and the regeneration air outlet of described desiccant wheel communicates with the air intake of described surface cooler.
The present invention compared with prior art, its remarkable advantage:
Low water capacity air, by continuous adsorption and desorb, is become high water capacity air, then uses efficiency of producing drinking water high by method of the present invention, the cooling water-fetching method that water withdrawal is large, from dry air, take out moisture, not only process is continuous, and making full use of the strong point of various method, efficiency is high, and power consumption economizes.
Device of the present invention make full use of desiccant wheel under the low humidity absorption water intaking ability and surface cooler at high humidity analyse by force wet ability, realize the object of fetching water from dry air continuous, efficient, energy-conservationly.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the method flow diagram that the present invention fetches water from dry air.
Fig. 2 is the apparatus structure schematic diagram that the present invention fetches water from dry air.
Fig. 3 is the structural representation of preferred version device of the present invention.
In figure, 10 desiccant wheels, 21 surface coolers (evaporimeter), 22 condensers.
Detailed description of the invention
As shown in Figure 1, the method that the present invention fetches water from dry air, comprises the steps:
100) moisture enrichment: by continuous adsorption and desorb, becomes low water capacity air into high water capacity air;
200) condensation draining: by high water capacity Air flow to dew point, separates out the moisture in air.
By continuous adsorption and desorb, low water capacity air is become high water capacity air, use efficiency of producing drinking water high again, the cooling water-fetching method that water withdrawal is large, from dry air, take out moisture, not only process is continuous, and makes full use of the strong point of absorption water intaking and cooling water intaking two kinds of methods, efficiency of producing drinking water is high, and power consumption economizes.
For ensureing the efficiency of cooling water intaking, should, by adjustment moisture enriching step, the dew point of its product high water capacity air be made to be not less than 10 DEG C.
Preferably, described moisture enrichment (100) step is specially: by the moisture absorption district of low water capacity air by desiccant wheel, to realize continuous adsorption, by the renewing zone of hot air by desiccant wheel, to realize continuous desorption, obtain high water capacity air.
In prior art, desiccant wheel uses in low moisture environments as dehumidification equipment, and object obtains the air drier than the air in the moisture absorption district entering desiccant wheel.And the exhaust of its renewing zone is discharged as waste gas.(see " dehumidifying technology " P263 ~ 267, Zhang Lizhi is write, Chemical Industry Press, in February, 2005 first edition) the present invention then utilize its water capacity high dexterously renewing zone exhaust as the air inlet of condensation draining, thus overcome condensation draining method directly from dry air efficiency of producing drinking water extremely low, even cannot get water problem.
Preferably, described condensation draining (200) step is specially: by the evaporimeter of high water capacity air by vapor compression refrigeration system, to separate out the moisture in air.
Be more convenient for like this implementing, and make full use of efficient, the energy-conservation feature of monolithic vapor compression refrigeration system.
As further optimization, in described moisture enrichment (100) step, be the air-flow flowing through desiccant wheel renewing zone after the condenser first flowing through vapor compression refrigeration system again for the hot air of desorb.
Make full use of the reactivation heat of waste heat as desiccant wheel of the condenser of vapor compression refrigeration system, the efficiency of whole method for fetching water can be improved further.
Be illustrated in figure 2 the device of fetching water from dry air realizing the method for the invention, comprise desiccant wheel 10 and surface cooler 21, the regeneration air outlet of described desiccant wheel 10 communicates with the air intake of described surface cooler 21.
Device of the present invention make full use of desiccant wheel 10 under the low humidity absorption water intaking ability and surface cooler 20 at high humidity analyse by force wet ability, realize the object of fetching water from dry air continuous, efficient, energy-conservationly.Water dish divided into by surface cooler 20 is standard practice.
Preferably, described surface cooler 21 is the evaporimeter of vapor compression refrigeration system.
