Description
Technical field
The present invention relates to a kind of device for preparing drinking water and drinking water preparation method, belong to purifier technology neck
Territory.
Background technology
Water is the source of human life, and existence is originally.Along with the development of industrial and agricultural production, water environmental problems becomes more
Coming the most serious, quality problem has had a strong impact on the orthobiosis of we mankind.There are 7.5 hundred million people in the whole world at present
Cleaning water cannot be obtained, it is provided that one huge challenge of safe drinking water, be also the most important target of the mankind it
One.As a example by China, at present in more than 600 city, the whole nation, more than 400 urban water shortage again, more than 100 city
City's serious water shortage, hydropenia city distribution by concentrate at present " three Norths " (northeast, North China, northwest) area and
East Coastal city is gradually spread to the whole nation.Along with the increase of population, the water resources carrying capacity in the whole world is also by face
Face more acid test.Water crisis will be the 21 generation main restricting factors that affect global economy sustainable development.
At some special dimension, the scarcity of water resource more highlights industry, economy, the restriction of social development
Property.The operation on the sea of such as boats and ships, the less small Fishing Boat of tonnage is because of placing space, line pipe arrangement, operating
Technology and the shortage of funds, seldom install sea water desalting equipment.The most such as water resource play in Islands Exploitation to
Close important effect.Most of island are away from continent, and without passing by foreign water, the exclusive source of water resource is by air
Precipitation recharges.Freshwater resources supply can be solved, be to be related to island to maintain resident living, carry out continuing
One of necessary requirement of exploitation, is the matter of utmost importance that must solve of Islands Exploitation.
Therefore, along with the problem of water resources crisis is more and more prominent, to the not drinkable water such as waste water, contaminant water
The research that purification reaches drinkable water is the most important.Traditional method for purifying water mainly has two kinds: the way of distillation and mistake
Filter method, the method being purified water by filtration is usually used in the purifier of high throughput, mainly passes through membrance separation
Technology or physical and chemical adsorption technology are by the magazins' layout in water inlet, thus obtain drinkable pure water.But
Generally membrane separation technique has the problem that (1) fouling membrane causes permeability rate to decline；(2) periodic replacement film is led
Cause operating cost is high.
Distillation mode carries out purified treatment to water can obtain pure distilled water, but Conventional espresso mode exists
Following deficiency: be first that speed is slow, owing to mostly it is by heating water so that it is produce substantial amounts of water
Steam, the current after then condensing collect.It is thus desirable to bigger heating surface area reaches to hand over big place
Reason amount；Secondly, energy expenditure is big, owing to the water of liquid needs to absorb substantial amounts of heat when becoming water vapour, but
Being when water recovery becomes the water of liquid, need again to discharge substantial amounts of heat, these heat are typically directly discharged into week
Collarette border, makes substantial amounts of energy loss.
For energy loss, it is thus proposed that new mode.As special in seen the U.S. of Patent No. US4216820
Profit just proposes a kind of technical scheme about heat-exchange apparatus.But extra heat-exchange apparatus adds equipment
Cost.In U.S. Patent number US6481232, disclose by the generation fresh water of atmospheric moisture.By inciting somebody to action
Air in heat and moist weather prepares steam in condensation in conditioner and dehumidifier.Air is adjusted
Regulating device is arranged in such a way: when extraneous air is by device, conditioner will be cold from air
Coagulate steam and produce the air of cooling simultaneously.In U.S. Patent number US6684648, disclose in heat
And moist weather extracts fresh water from extraneous air so that the remote districts rare in water resource can get
Fresh drinking water.Portable and compact device is designed to produce drinking water, including using ultraviolet, smelly
Oxygen, chlorine, activated carbon and filter and fluorine and oxygen additive, to make drinking water fresher for taste and health
With containing mineral.For more Energy Efficient, water flows by gravity or under the auxiliary of little pump.Available temperature
, heat, cold or cold carbonized drinking water or even for the fresh water of other purposes.At WO
In 2004/027165Al, disclose air drier instrument and produced from the steam of atmospheric moisture by condensation
Raw drinking water.But this instrument is not energy saving, and the water produced is the coldest, and it needs fan to produce
Fresh water.WO2007/009488A1 discloses a kind of air cooling method, and wherein air is first by the coldest
But agent (initial coolant) cools down, and is then cooled down by Main Coolant (primary coolant), to strengthen the cold of water
Solidifying.The method is saved energy and improves the condensation of water, and the method passes the energy saving of cooling stage through discussion also
And the coolant for producing drinking water is discussed.CN102510980B proposes a kind of use and drinks as dew
Energy saving and the eco-friendly multifunctional air adjusting means of the generator of water, hot water and desiccant produce
Fresh and cold air, dew, for the hot-air of exsiccator, for taking a shower or other purposes
The method of hot water and machine.This system comprises air-cooled condenser, compressor, thermostat, cold-producing medium etc..
The primary limitation of such device is that the yield of condensed water is limited to the content of saturated steam in air.When
Ambient humidity relatively low (such as: the season of dry climate or colder), the yield of condensed water will be greatly reduced,
Energy utilization rate reduces.Simultaneously from the description of more above-mentioned patents, when examining, it can be deduced that there is no one
While item patent steam in utilizing aerial condenser (cooler) condensation air produces condensation drinking water
Utilize heat energy produced by the hot junction of air conditioner to carry out heated waste water and produce high temperature saturated steam.This high temperature saturation water
Steam can be by further by condenser cold end cooling preparation condensation drinking water.
Traditional distillation-condensation method is used for preparing condensation drinking water major defect and is that energy consumption is big.Whether add
Thermal distillation waste water and condensed steam, or directly condensed steam from air, the transmission of its energy is all single
To linear.I.e. heat passes to a low side from a high side.As:
1: thermal source → waste water → steam → environment (generation condensed water)
2: steam → condenser (generation condensed water)
When water vapor condensation forms aqueous water, discharge substantial amounts of heat.This heat is released in said process 1
In surrounding, or in said process 2 around the hot junction of condenser is dispersed into the form of heat energy ring
In border.No matter process 1 and 2 all causes substantial amounts of energy loss.
