Description
Technical field
The utility model belongs to air water-intaking technical field, particularly a kind of device that can extract moisture from drier air.
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 purpose of this utility model is to provide a kind of device of fetching water from dry air, can preparing fresh from drier air continuous, efficient, energy-conservationly, meets arid area water demand.
The technical solution realizing the utility model object 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 utility model compared with prior art, its remarkable advantage:
Device of the present utility model 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, 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, moisture is taken out from dry air, not only process is continuous, and makes full use of the strong point of various method, realizes the object of fetching water from dry air continuous, efficient, energy-conservationly.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the apparatus structure schematic diagram that the utility model is fetched water from dry air.
Fig. 2 is the structural representation of the utility model preferred version device.
Fig. 3 is the method flow diagram of fetching water from dry air.
In figure, 10 desiccant wheels, 21 surface coolers (evaporimeter), 22 condensers.
Detailed description of the invention
As shown in Figure 1, the device that the utility model is fetched water from dry air, comprises desiccant wheel 10 and surface cooler 21, and the regeneration air outlet of described desiccant wheel 10 communicates with the air intake of described surface cooler 21.
Device of the present utility model 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, not shown.
Preferably, described surface cooler 21 is the evaporimeter of vapor compression refrigeration system.
As shown in Figure 2, as further optimization, the air outlet of the condenser 22 of described vapor compression refrigeration system communicates with the regeneration air entrance of described desiccant wheel 10.
As mentioned above, 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.
As shown in Figure 3, be the method flow of fetching water from dry air, the method 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 utility model 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.
