Abstract
The utility model relates to an osmose type desalination device of seawater, which is made of the base materials of semi-permeable membrane. A person with the osmose type desalination device of seawater can largely absorb solution containing high concentration solute, forming the concentration difference between sea-water and the solution, and directly getting the solvent and the freshwater of sea-water by osmosis. The utility model has the advantages of simple structure, convenient operation, low cost and stable operational modes. Compared with a self-system, the quantity of water is more, and the utility model is of great moment for saving lives at sea (in particular to saving a person).
Description
The utility model is a kind of middle-size and small-size device of processing seawater to make it to supply the people to drink.Particularly a kind of semipermeable membrane principle of utilizing is made, with interior Sheng high density people can be relatively large the absorption solute form with the concentration of seawater difference, can obtain sea water solvent---the device of fresh water.The utility model simple structure, mode of operation is stable, and is big from the system water yield, easy to use, cheap relatively.
Known seawater is a kind of aqueous solution that contains 3～3.5% salinities (solute), can't directly drink for the people.Known a series of people can relatively large absorption solute the aqueous solution all can ooze with certain proportioning and seawater formation etc.Such as glucose solution (about 20%), ethanolic soln (about 7%), glycine (about 9%) etc.
Known middle-size and small-size sea water desalinating plant mainly contains Zheng Evaporated method, ion exchange method and reverse osmosis method.Zheng Evaporated method is with seawater heating vaporization, makes vapor condensation again and obtains fresh water.Method is simple, and the system water yield is big.But this method has volume bigger, and working conditions is subjected to the defective of the big and big energy-consuming of environmental constraints, especially can't be used for single lifesaving.Ion exchange method, its exemplary device are silver-colored formula zeolite emergency survival ion-exchange medicament.This medicament can generate the insoluble substance precipitation with salinity wherein, thereby isolate fresh water after closing with seawater is wet.The defective of this method is that the system water yield is little, the cost costliness.
The reverse osmosis method water generator is that (semi-permeable membranes is that penetrant is had optionally film with a semi-permeable membranes.Be used for mainly containing of sea water desaltination: cellulose acetate membrane (dry type and wet type) and aromatic polyamide film, its shape, thickness and physical strength all can be formulated according to processing request) be separated out sea-water area and fresh water district and sea-water area apply greater than penetration of sea water press (infiltration be when solution and neat solvent (or two kinds of solution that concentration is different) under the situation that semi-permeable membranes separates, the phenomenon that solvent (or than the solvent in the dilute solution) spreads to solution (or than strong solution) by semi-permeable membranes; Osmotic pressure is to cause that the pressure of infiltration takes place solution, is numerically equal on original solution to stop solvent to enter the mechanical pressure of solution just) with the pure water reverse osmosis in the seawater in the fresh water district.The advantage of this method is that power consumption is less, and system back water quality is better, and defective is restricted by high top pressure operation and semi-permeable membranes performance, and equipment is more expensive, uses inconvenience.
Task of the present utility model is made a kind of in addition power consumption, the little system water yield of volume is big, can be used for single lifesaving, sea water desalinating plant easy to use, cheap.
Task of the present utility model is finished like this: make a bag that can seal with semi-permeable membranes.Such as the bag that can be hollow ball shape, the support thereby the Zhe that can wrinkle do not receive little in not having.Be placed with supersaturation (such as the 90%) solution that the people can relatively large absorption solute (such as glucose, ethanol, glycine mixed solution) in the bag.The bag outside surface should be furnished with a porous catch net, the protection semipermeable membrane material.Be harvesting safety and health, outermost layer of the present utility model can have an airtight aluminum or mould box, the cover of system, or the bag of flexible packing material system (when the semi-permeable membranes requirement was received and kept with wet type, airtight outer box (bag) can guarantee that its inside is moistening.）
Use the utility model, can put down gently in the seawater with the semi-permeable membranes inner bag by taking out in the outer box (bag).At this moment, the bag in supersaturated solution and the concentration difference between seawater will make seawater solvent--fresh water is in penetrating into bag.This process will proceed between bag interior solution and seawater to form and only wait when oozing.According to solute difference or mixed solution proportioning, the fresh water amount that is penetrated in the bag approximates the several times of original solution amount to tens of times.This solution can be drunk at leisure for the people.The utility model volume is little, and the system water yield is big, easy to use, cheap.Lifesaving at sea (especially single lifesaving) aspect, of many uses.
Do concrete introduction below in conjunction with a kind of embodiment of the present utility model:
Fig. 1 is the cross-sectional schematic of embodiment.
Fig. 2 is the synoptic diagram that embodiment makes water.
With reference to Fig. 1, in the aluminium box (1) of a band sealing plug (2), splendid attire the system water bag (3) that wrinkle Zhe that a semi-permeable membranes makes packs up.System water bag (3) outer wall is a porous nylon system catch net (4), adorns the aqueous solution (5) of oversaturated glucose, ethanol mixing solute in the system water bag (3).System water bag (3) top is sealed (6) and is sealed the tight softish polyethylene suction pipe (7) that also sealed in advance, suction pipe top (8) sealing fully.When present embodiment used, with reference to Fig. 2, the sealing plug of outwarding winding (2) took out system water bag (3) and puts down gently in seawater (9).Through for some time, the fresh water in the seawater (9) will be penetrated in the system water bag (3) and go (indicating with arrow) that system water bag (3) is expanded, and at this moment, can inhale solution in the drink bag at leisure as long as sting open pipe top (8).
Claims (4)
1, a kind of middle-size and small-size main sea water desaltination (drinking) that with the semipermeable membrane material is the basis is made is installed, it is characterized in that semipermeable membrane material makes, the bag that can seal (3) is placed with the solution that the high density people can relatively large absorption solute (such as glucose, alcohol mixed solution) in the bag.
2,, it is characterized in that bag (a 3) outer wall is furnished with the porous catch net by the sea water desalinating plant of claim 1 regulation.
3,, it is characterized in that outermost layer is an aluminum or the box of moulding system cover or soft packaging bag by the sea water desalinating plant of claim 1 regulation.
