Abstract
The invention relates to a method for getting water from air through phase change caused by light and using the water for cultivation. Mainly through irradiation of sunlight in the daytime, a material with a special structure is enabled to have hydrophilicity to absorb water in the air under the sunlight in the daytime; and at night without light, phase change is caused, the material is enabled to have hydrophobicity, the water is separated from the material and flows out to serve as drinking water for people or be used for plant cultivation.
Description
Technical field
Illumination phase transformation air water-intaking and the technical field that is used to cultivate are to belong to physical phase transition field and agricultural cultivation field, mainly are by the solar light irradiation on daytime, make the material with special construction, when by day illumination being arranged, possess hydrophilic property absorbs the water in the air, to evening when not having illumination, undergo phase transition, make material have hydrophobicity, water breaks away from material, and current are come out, be used for the people and drink, or be used for plant culture.
Background technology
Tellurian fresh water content only accounts for 2.53% of global Total Water, and wherein 68.7% belongs to the solid glacier, is distributed in the high mountain and the polar regions that are difficult to utilize, and part fresh water is buried underground, is difficult to exploitation.At present, the fresh water that the mankind can directly utilize is taken from underground water, lake fresh water and river bed water, and along with going from bad to worse of environment, it is more and more rare that these freshwater resources are just becoming, especially in desert and area, island.Earth surface has 15% desert area and 70% area, ocean, and wherein desert area population has 6.28 hundred million, and the population that on the island and coastal area lacks fresh water is more.The conventional method that solves the water supply problem in above-mentioned area comprises communications and transportation and two kinds of approach of desalinization.The communications and transportation cost is higher, and desalinization is also inapplicable to the area of salt solution rareness, and because its technology and cost limit, equipment is large-scale, is not suitable for being extensive use of.Therefore, people begin to seek other method and obtain freshwater resources.Be rich in fresh water in the atmosphere, and not limited by the region, especially in island and coastal area, air humidity is higher, it is estimated, contain the steam of about 14 000 km3 in the atmosphere, and the fresh water total amount on the face of land has only 1200 km3[1].Up to the present, almost nil to the utilization rate of fresh water in the air.In sum, the air water-intaking technology is containing the great potential that solves the rare problem of fresh water, and allow the most effectual way of desert afforestation, can make plant need not irrigate plantation, the method for present air water-intaking has following several: 1 dewfall condensation method, 2 separating and condensing methods, the dewfall condensation method is exactly by pressurization or cooling the moisture dewfall in the air to be come out, this method complex structure, inefficiency is difficult to popularize.The separating and condensing method is exactly by molecular sieve or silica gel and some composite materials, the adsorbent of some liquid that also have, make above hydrone is adsorbed onto, by solar energy or other energy, hydrone is evaporated then, allow steam cool off then, obtain water, these are more a lot of than dewfall condensation method, also have complex structure, inefficiency is difficult to popularize.
Summary of the invention
2 kinds of methods above analyzing, the basic principle of dewfall condensation method is to allow air cooling-down arrive certain temperature, water will dewfall come out, because the concentration of moisture when temperature is high in air is big, the scheme of the basic natural phenomena design that concentration is little when temperature is low, the basic principle of separating and condensing method is that adsorbent absorbs large quantity of moisture in air, then with the method that heats up, allow hydrone absorb energy, the absorption that breaks away from adsorbent, cooling becomes water then, the technology of our invention, principle has identical character with titanium dioxide in fact, hydrophily is bigger when illumination is arranged, very little with regard to hydrophily when not having illumination, the material of our usefulness is through particular design and product processed, performance is strong more a lot of than titanium dioxide, it is characterized in that the adsorbent material that we make is fetched water material possess hydrophilic property when illumination according to following method, airborne moisture was also many when simultaneous temperature was high, hydrone is connected on the adsorbent by the effect of chemical bond, and when not having illumination, adsorbent material will become hydrophobicity, hydrone will break away from adsorbent, and water just flows out along material.If with the material of adsorbent as the outside, make a basin, the earth of basin the inside and basin insulation are opened, and the water of getting directly is stored in the basin earth, plant plant again on this earth, and this plant can will be watered never.
Description of drawings
Accompanying drawing 1 is the schematic diagram of illumination phase transformation air water-intaking, and 1 represents sunshine, and 2 represent the adsorbent of new material, and 3 represent the hydrophobic diversion passage of adsorbent, and 4 represent the pore of adsorbent, and 5 represent delivery port, 6. represents the fixed mount of outside.
Specific implementation method
The material of novel research and development, make slices, fixed with the framework in outside then, allow material be shined upon as much as possible, daytime is under the irradiation of the sun, some molecular links of adsorbent the inside change, will from hydrophobic state slowly become hydrophilic state, will absorb the hydrone in the air, to evening when not having sunlight, some molecular links of adsorbent the inside will be got back to original state, will from hydrophilic state slowly become hydrophobic state, hydrone will be from top disengaging, flowed down along hydrophobic channel, collect operation so repeatedly, the system water that does not stop then by delivery port.If with the material of adsorbent as the outside, make a basin, the earth of basin the inside and basin insulation are opened, and the water of getting directly is stored in the basin earth, plant plant again on this earth, and this plant can will be watered never.
Claims (2)
1. an illumination phase transformation air water-intaking and the method that is used to cultivate, it is characterized in that, the adsorbent material that we make is according to following method water intaking, material possess hydrophilic property when illumination, airborne moisture was also many when simultaneous temperature was high, and hydrone is connected on the adsorbent by the effect of chemical bond, when not having illumination, adsorbent material will become hydrophobicity, and hydrone will break away from adsorbent, and water just flows out along material.
2. method according to claim 1, the method that it is used to cultivate is, the material of adsorbent as the outside, make a basin, the earth of basin the inside and basin insulation are opened, the water of getting directly is stored in the basin earth, plants plant again on this earth, this plant can will be watered never.
