Description

Floating type portable solar-energy water purifier

The utility model is a kind ofly to use during for field worker, battlefield military personnel or maritime peril person people living first aid, utilizes the device of solar thermal energy distillation purification tap water.

At present China's field worker and the fighter of army still lack a kind of simple and easy, effective, be convenient for carrying and do not consume conventional energy resources and medicament, natural water (comprising seawater and contaminated river, lake, pond, spring) straight run distillation can be purified to tap water, reusable equipment.

As for the technology and equipment that utilizes solar distilling to desalinize seawater, before more than 100 years, just occurred abroad.China at Guangdong and offshore islands one band, also successively has been developed into the large-scale stationary installation that sun power desalinizes seawater since the seventies.The typical structure of this class device is: under the ramp type glass covering, be provided with the water tank of horizontal positioned, all around sealing.Sunlight sees through top cover and is mapped in the water tank, makes the basin maritime interior waters be subjected to thermal evaporation, and impurity and salinity remain in the basin.Water vapor rise to arrive the glass roof place, because of glass is subjected to the cooling of ambient atmosphere, so water vapor discharges heat at the top cover internal surface, is condensed into distilled water.After water droplet bred a certain size, under the effect of earth gravity, beginning flowed into water leg to glass inclined-plane, lower edge, was converged to by water leg and stored standbyly in the fresh water container, finished the process of sea water desaltination.Existing sea water desalting equipment, what collector area was little has nearly hundred square metres, and big reaches thousands of square metres.Every square metre of collector area is produced about 2.5 kilograms of fresh water average every day.Existing apparatus exists distillation and condensation to confuse a Room, the phenomenon of sunlight incidence window and the shared one of water vapor condensation radiating surface.From the desalination flow process, this structure is obviously unreasonable.Perhaps this is to cause the inefficient reason of original system place.

The purpose of this utility model is that a kind of improved design will be provided: at first, will absorb heat and separate with condensing chamber with the diverse evaporator room of heat release function.For improving the temperature of evaporator room, to installing air heat insulating layer around the evaporator room additional.For quickening the condensing rate of water vapor, make full use of natural water source and come the cooling heat dissipation face, and make full use of the condensation that discharges in the condensation process.Middle transition chamber between two Room can effectively " be pressed into " condensing chamber with water vapor, and stops the water vapor in the condensing chamber to drive in the wrong direction.Secondly, enlarge the adaptability of system.Make it can be in any place that sun resource is arranged, no matter to seawater, still the water in contaminated river, lake, pond, the brook can both carry out effective purifying treatment.The 3rd, improve material and structure, with its " microminiaturization ", so that folding carrying, make things convenient for individual soldier individual in danger or in emergency circumstances, use during independent self-rescuing.

The purpose of this utility model is achieved like this:

One, with the transparent plastic film of inflation in the middle of double-deck, constitutes the sunlight incidence window.The benefit of doing like this has two: one can prevent that ambient atmosphere from by convection current and conduction, causing unnecessary thermosteresis to stilling chamber.Two can improve the temperature of air casing between the two-layer transparent plastic film, make water vapor be difficult for condensation on sunlight incidence window internal layer membrane face, influence sunlight and effectively penetrate, and reduce the incident loss of sunlight.Obviously, the mechanism of this point and original device utilize the practice of the glass surface of sunlight incidence window as the water vapor condensation device, have the difference of essence.

Two, evaporator room around, form with expandable plastic film garden pipe.This structure also has three benefits: one, the frame that inflation propels the price of can play the effect of system support and connection.And total system is convenient to folding and collection after the exhaust.Its two, garden cast inflation sidewall can play to the stilling chamber insulation simultaneously, reduce thermosteresis and guarantee that there is enough buoyancy in system, so that float at the water surface.Three, if around the garden pipe go up the inboard transparent plastic film of use, the following outside can increase the sunlight transit dose with reflective plastics film formation, is beneficial to raising stilling chamber temperature, reduction condensing chamber temperature.

Three, in order to reduce sunlight incident loss, should there be a pitch angle that faces south in system itself.The utility model is realized tilting to support with the garden column type air bag of an independent inflation.This design can realize four purposes simultaneously: (1), realized tilting on the sunny side of system, be convenient to sunlight incident; (2), after system tilts on the sunny side, stilling chamber forms a passage obliquely.The water vapor that is evaporated from the suction core with following the rule of hot gas flow come-up, enters transition chamber along passage like this.Simultaneously in condensing chamber, under the effect that reduces because of the relative constant pressure of water vapor condensation smaller volume, pour into the water vapor in the transition chamber continually, will in condensing chamber, freely expand, the result is condensed there and is reduced to water molecules.(3), after the garden cylindricality support air bag inflation, with going to the bottom of system and going to the bottom of stilling chamber, forming longitudinal section jointly is leg-of-mutton in the shade cavity, the condensing chamber of system that Here it is.Leg-of-mutton acute angle place, because buoyancy is little, structure is born a heavy burden bigger, is condensation indoor location lowest part, thereby becomes the optimum position of collecting condensation distilled water just.Distilled water is here by an elongated fistulae that the reverse checkvalve valve can be housed, and it is standby that the distilled water input is suspended on outer field water purification (fresh water) storeroom.(4), because the existence of the garden column type air bag of big buoyancy can be guaranteed system under any unforeseen circumstances, the upset of unlikely generation systems on this direction.Notice if system takes place just the natural water without distillation purification to be poured in down a chimney into condensing chamber to this direction upset easily, is sneaked in the water purification storage vault at last, causes pollute the second time of purifying waste water.As long as sneak into one, not only all that has been achieved is spoiled under certain particular case, and can cause the contaminated and serious consequence that can not normally use again of internal system.

Four, " water tank " of system---the suction core is located between evaporator room and the condensing chamber.Promptly around inflate the following tangent plane of garden pipe, seal one section (accounting for total length about 90%) from bottom to top with one deck reinforcement plastics film, constitute the carriage of so-called suction core.On carriage, " be stained with " one deck and be imbued with the adsorbing suction core of kapillary with " latitude lattice sieve " nylon buckles.For example: degreasing cotton fiber black towel can fill makees the suction core.The crack that stays is given in advance by tangent plane under the pipe of inflation garden in the lower end of black towel, directly immerses in the nature water.Pending natural water is entered the distillation of evaporator room thermal-arrest by the absorption of the kapillary on the black towel.This structure has two purposes: the first, can make full use of the heat of condensation that condensation discharges in the system.Because be filled the black towel of moisture content, directly be layered on the film carriage, and the bottom surface of the film upper base of condensing chamber just.The water vapor heat that condensation discharges on this layer film will directly be absorbed by the black towel, promotes evaporation of water.Condensing rate is fast more, and the heat that discharges is many more, smaller volume behind the water vapor condensation, and " negative pressure " of generation effect is obvious more, is beneficial to more more water vapor " induced " to go into condensation in the condensing chamber.The optimum flow process that formation is mutually promoted is improve system purification efficient basic.The second, black towel lower end directly is immersed in the nature water, can not only realize adsorbing, the automatization of thermal-arrest, evaporative process, and be convenient to people to generally polluted, turbid water matter, before entering system's distillation, handle.Method is: with the two bags gac parcel identical with the towel width, place the both sides of towel head outside the system of stretching out, with one deck porous plastics (sponge) it is wrapped on the towel head.Work as nature water like this and see through porous plastics and active carbon layer, when being immersed on the towel, can being filtered and removing poison.

The utility model is compared with existing solar-energy sea water desalting equipment or allied equipment: because the separating of evaporator room and condensing chamber; Can play the existence of " thermal insulation " transition chamber that " thermal source " and " heat is converged " separated; And the iterative structure up and down of evaporator room and condensing chamber.Not only will filter a suction-thermal-arrest distillation-condensation-fresh water and converge, the phase physical change process of whole water is made in order, and with its be combined in compactly one rationally and mutually help "

" in the font space, not only micro volume, and improved thermo-efficiency.In addition, system has the simple and effective filtering poison device of crossing, and is strictly on guard against and oozes mixed function, thereby can not only desalinize seawater, and also can distill other by general polluted river, lake, pond, spring.Enlarged use range.System changes working order into from the folding portable state, without any need for special use or general utility tool, and the specialized operations technology.Any one user after unpacking, need only chew by special-purpose gas respectively according to indication that is printed on system corresponding site place and simple prompting, and with sunlight entrance window insulating gasbag, frame garden tube airbag and the garden of support cylindricality air bag blow full air.Well anti-drift safety rope of bolt or the directed anchor line of counterweight.Put into water then and align sunlight, system just can start to work voluntarily.Because system forms with nontoxic plastics film heat bonding, thereby cost is lowly held concurrently, technology is simple, weight is slight, is convenient to fold carry.And these all are that original device is not available.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing 1 is the longitudinal profile diagrammatic sketch of the portable type solar energy water purifier that the utility model proposes.

Accompanying drawing 2 is that the utility model is at accompanying drawing 1E-E place cross-sectional configuration synoptic diagram.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

With reference to accompanying drawing 1, sunlight incidence window of the present utility model is made up of two-layer transparent plastic film (1).It between the double-layer films independent sealed air heat insulating layer (2).Frame is to be transparent plastics with half around the system, the closed rectangle plastics garden pipe (3) of the middle inflation that half gets up for silvery white plastic cloth thermo-welding.More than two partly add garden, upper edge pipe (3) tangent plane down, the reinforcement plastics film (4) that is bonded together with the garden pipe has from bottom to top been formed the evaporator room (5) of system jointly.The area of evaporator room accounts for about 90% of closed rectangular area that plastics garden pipe (3) surrounded, and 10% is isolated from bottom to top by a dark plastic cloth in addition, is so-called " thermal insulation " transition chamber (7).Locellus plastic interlayer (6) is not that two Room are cut off fully, and it just cuts off about 2/3 cross-sectional area from bottom to top.The effect that this interlayer is installed is: be strictly on guard against when reversal dip takes place system's contingency that the natural water that is on the core that absorbs water in the evaporator room is sneaked into condensing chamber easily, cause pollute the second time of the good fresh water of distillation purification.In addition, the passage section between evaporator room and the transition chamber receive little after, make in the evaporator room under the solar thermal energy heat effect the constantly water vapor of evaporation gasification, be able to continuously with higher dynamic pressure and " clamp-on " transition chamber.Forcing the unlikely adverse current of water vapor that early is introduced in the transition chamber to return to evaporator room confuses us and is the flow direction of its regulation.Suction core (8) in the evaporator room is such parts, with black towel or other a gentle material that is imbued with the kapillary adsorptive power through skimming treatment, as artificial sponge, porous plastics one class.Use several segments " latitude lattice sieve " nylon buckles (20) " stickup " all around on reinforcement plastics film (4), the material lower end of this piece absorption moisture content directly reaches outside the system interspacing from giving, and is immersed in the natural water area.Its effect is natural water constantly to be adsorbed enter evaporator room, directly receives solar radiation heat energy, under " high temperature " environment of evaporator room, water evaporates is become water vapor.For relatively more muddy or suspect deleterious natural water, can be in the lower end of the sorbing material of the system of stretching out, each pad last one little rectangular activity charcoal powder bag (9) of both sides is used a porous plastics (10) that it is wrapped simultaneously, and is buckled with clip.Like this when moisture content by porous plastics (10), see through activity charcoal powder bag (9) again, arrive suction core (8) at last, and be adsorbed when entering the evaporator room distillation, its impurity just can well be filtered removing.(11) in the accompanying drawing have been the stiffening web of the plastics film (4) of sorbing material supporting role.

Enter " thermal insulation " transition chamber (7) at water vapor afterwards, because the transition chamber position is higher, and under the direct irradiation of solar thermal energy, so the temperature here is still higher, water vapor is difficult for condensation.These high temperature saturated gases form certain malleation and look about outlet.Just transition chamber tiltedly below because garden cylindricality air bag (12) and inflating under the supporting role of frame (3) formed a bottom here and has been immersed in the cold water, " darkness " corner that the chamber of being evaporated, top tightly covers, it is exactly our condensing chamber (13).Water vapor " expansion " is after condensing chamber, because here with upper base (4), go to the bottom (14) all are in the heat absorption state, and temperature is lower, thereby water vapor will be very fast discharges heat of condensation at the bottom of these two and condenses into moisture content.The heat that water vapor discharges in condensing chamber, the water that is attracted to soon in suction core (8) of upper base absorbs, and that goes to the bottom then has been directly passed to natural water in the extraneous waters.Therefore the condensation room temp is high does not all the time get up.Because water vapor volume in condensation process dwindles greatly, how many water vapors of successively coming in so condensing chamber is interior, but pressure is lower than the transition chamber under the solar radiation always.It just has constantly and " induces " water vapor to enter in a large number like this, and it is condensed into the infinite potentiality of water rapidly.On upper base (4) and go to the bottom (14), be condensed into the droplet of distilled water.When volume expanded after to a certain degree, under the effect of earth gravity, will flow to the lower bottom of potential, at last by check fistulae (15), it is standby to converge in the fresh water storeroom storage.

With reference to accompanying drawing 2; fresh water storeroom (16) is a water bag made from nonpoisonous and tasteless food product pack plastics; weld what a water drinking tube (17) in the bag in advance; the poly-distilled water (18) that exists in the bag; drinking person can directly be drunk by unpluging the anti-pollution protective guard of water drinking tube (19); perhaps, by water drinking tube (17) fresh water is discharged it and use with hand extruding storage water bag (16).The existence of elongated check fistulae is very important, and it can be protected and be strictly under the condition of uniting in the open air, and is any when jolting significantly even overturning, and the also unlikely fresh water that the drop pinching is got up pours in down a chimney to cause into condensing chamber again sheds loss.

Material selection structure size and the water yield per day of the utility model product can come special setting with object and main environment for use according to different. As being that casualty is for subsequent use on the naval vessel, can making the Inflated floating thing with rubber fabric, and join the automatic compressed air gas filling bottle. Collector area can reach one or two square Rice. Bigger system also can fill in case of necessity and do living raft use. Mountain area, the single adapted in battlefield, naturally should be smaller and more exquisite, collector area can be controlled in 0.3-0.5 square metre of scope, and water yield per day 500-800 gram can reach minimum instructions for use.

The utility model is simple in structure, and the raw material range of choice is extensive, and price is low to be held concurrently. It is simple and easy that system is made in processing, worker's die clamper and frock that need not be special, and any plastic products and toy for children manufacturer can both manufacture.

The utility model does not consume conventional energy resource, the efficient height, does not need special operation operation technique, and construction weight is slight, is convenient to folding carrying. Thereby be the battlefield army personnel, naval vessel, air personnel, geology, scout, the first aid station set that exploration, scientific investigation and traveller are desirable.
