Description

The method of purifying contaminated water and device thereof

Relate generally to water purification of the present invention particularly relates to the method and the device thereof of purifying contaminated water.

Invention described here is used for and will takes from all treated water supply centres, city, also can take from well or spring and other water source, preferably those water without the water source that pollutes to heavens change into intrinsically safe drinking water, and every processing 1 gallons water only need expend several pennies.

The present invention is based on understanding to such fact, although promptly people require or think that running water is safe to the mankind's consumption, but in fact in running water, contain a considerable amount of pollutants or pollutant, even these pollutants or pollutant are in fact harmful or poisonous, use outward appearance but at least also influence it because of smell that variable color or muddiness or generation are disliked or taste.Moreover, at least in some cases, although city tap-water is handled (very serious sometimes) to remove harmful organism, such as bacterium or the like through fluorination treatment or chlorination.Because big city, particularly river is had to use in the big city resemble New York, replenishes their cistern as the water with Hudson, particularly all the more so under rapid or lasting period of drought, thus make running water be infected with still further aggravation of problem.So containing various pollutants in the river, such as Polychlorinated biphenyls (PCB) or other carcinogenic compound, and various industry and home scrap (that handled or untreated) all the approach by separately enter the korneforos.And, contained quite abundant natural or synthetic organic material and bacterium and other biofouling thing in the river already.

Apparently, river is unprocessed is not suitable for consumption.Thereby these rivers were handled through superchlorination before being introduced into cistern usually, and were chlorinated again when aqueduct supplies water from cistern.Yet although for killing most harmful organisms, during especially for contaminated water, chlorination is effectively, has also produced three carcinogenic methine halides.Moreover, at least in some old city water systems, in distribution duct, had the inoperative organism of pair chlorine to spread and caused dangerous pollution.Giardia lamblia tumour (Giardia lamblia cysts) can cause that small intestine infects, and this is the example of the organism of a harmful but anti-chlorine.In addition, toxin or other harmful substance may be incorporated in the water of having handled in the distribution conveyance conduit of water such as lead, copper, zinc or asbestos.

In addition, contain the organic compound of high poison in the trade effluent, and be used for pesticide, herbicide, fungicide and the similar substance of agricultural, more need not carry the various compounds that are used for the danger of family, water generates is polluted.The common salt of high-load and other sodium salt for example, from the intrusion of seawater, or are introduced owing to certain water softener and processing method, can make the sodium that causes undesirable high-load in the drinking water.Other contaminant salt comprises the nitrate that may cause methemoglobinemia (or " blue babies "), and can cause the fluoride of dental plaque and osteopathy.High nitrate concentration can be infected with by the dirt of people and animal because of the water source and cause, perhaps, especially in arid and hinterland, also may be owing to natural (geography) pollution causes.Being infected with similarly of fluoride both can be caused by activity of human beings, also can cause owing to being infected with naturally.Also toxic heavy metal salt is being widely used in industrialized society, or exists as byproduct in some production process.Such heavy metal salt comprises, as, cadmium salt, chromic salts, nickel salt, lead salt and arsenic salt (this salt also can cause cancer).At last, in the age of today, the pre-use of the production of nuclear weapon, test and the state of war, same because the generating and the accident of nuclear power station, with in processes such as the exploitation of radioactive substance, processing, refining and removings, cause the radioactive substance that is harmful to quantity to dissolve in or the chance of bringing in the water source increases year by year.

Based on above viewpoint, the unique method that assurance certain harmless while of drinking water is removed most (if not all) pollutant again clearly is when in use running water directly to be carried out last purification.Thereby, the multiple Apparatus and system of finishing such purpose has been arranged so far.Thereby, for example, someone propose at first with tap water filter with remove granular pollutant or other can be absorbed by filter medium such as active carbon or charcoal, absorption or the pollutant collected, then the water that filters is heated to high temperature, perhaps be increased to its boiling point, thereby kill all or most at least bacterium, plumule, virus and other biofouling thing, lower boiling material is overflowed and enter atmosphere on every side.Yet, experience is in this way shown, at least in some occasion, the result who draws as the method is rather disappointed, particularly stay in the filtered water and can not discharge, and some material can filter and still stay in the water by heating because of many contaminants after first the filtration.The filtration of this poor efficiency obviously is because detention or the retention time of water in filter that is filtered is too limited.

Also the someone proposes the water that relies on distil process to obtain to purify when using running water, and many devices are used to such distillation principle, and some of them are rather complicated thereby correspondingly cost an arm and a leg.Yet, this method also suffers difficulty because of a rather serious deficiency, this weak point also exists such fact, it is the material that at least some boiling points are lower than water, to evaporate prior to water, the atmosphere towards periphery that escapes but but the condensation phase under connecing in still-process participates in the water, thereby in fact the concentration of these materials in distilled water has increased, particularly consider such fact, promptly be not that all water can both be used for distillation, also non-all water that can be used to distill all positively change into steam or steam and condensation again, particularly on each surface that contacts with water, form involucrum or incrustation scale or for other reason for the mineral matter that contains in the water that prevents to be distilled and other high boiling substance, all the more so when distilling in batches rather than continuously.Equally, the common consumes expensive of still-process because this needs enough energy, particularly when water when liquid state changes into gaseous state and is water vapour or steam.

U.S. Patent Application Serial Number 300,423, the device of 442,951 and 443,599 pairs of the above-mentioned types and the example of equipment that is used for these devices are described, but all these examples have all gone out of use.For example, patent application serial numbers 300,423 patent has disclosed a kind of water distillation apparatus, and the water that must purify flows to evaporimeter by the approach that an extremely circles round, thereby so that makes water increase the chance that its holdup time makes the low boiling pollutant increase volatilization and overflow in this device before arriving evaporimeter.Patent application serial numbers is that 442,995 patent has been described another distilling apparatus, and water is evaporated in evaporimeter and condensation in an independent container in this device, and this container is built to can collect distilled water and inner surface through sterilization.Yet in all these devices, water is not process recirculation all, also in the approach of current direction evaporimeter filter is not set, thereby the degree of purification that these devices obtain is lower than what be scheduled to.In addition, patent application serial numbers is that 443,599 patent application has disclosed another kind of distilling apparatus, and the water that must purify in this device is at first through a precipitation equipment, and fills it up with continuously, and changes in the storage that steam is condensate in an external condensation then.Yet, even the recirculation that does not yet have part to purify waste water does not here make the passage of these water recirculation by any filter yet.

Thereby general objects of the present invention is to avoid shortcoming of the prior art.

More particularly, an object of the present invention is to provide a kind of method for purifying water that can finish very high degree of purification.

Another object of the present invention provides a kind of advised method, with the lower pollutant of removing the overwhelming majority's (even not all kind) in the water that expends.

The purpose that the present invention follows is a kind of device that can finish said method of design, and relatively simple for structure, and production expends not high, and is easy to use, and is easy to operate.

Another object of the present invention is the water purification installation of design the above-mentioned type, enables to remove the contaminant that the mid-boiling point that anhydrates is lower than water, also can remove to deenergize at least to be filtered the contaminant of medium collection.

There are characteristics in significantly other purpose that will become after reaching to achieve the above object in the method that the present invention purifies waste water, this method comprises the steps: predetermined limited impure and water that must purify is directed at a filter; The water of introducing by filtering to obtain the water that part purifies; In the confined space, collect partially purified water and form a waters at this; Heat water that this part purifies make it temperature near or reach its boiling point; Again the water that this part is purified imports same filter; Then repeat to make water body satisfy the requirement of further purifying to the step that partially purified water filters, accumulates and heats, the degree of being infected with in these water is lower than predetermined level.A present invention so far special advantage of described method is, by repeatedly partially purified water being filtered, only can be filtered off with water, thereby from filtered water, remove by the contaminant that filter situation once relatively has more ratios to remove after filtration.In addition, make it to reach or near its boiling point, in the atmosphere around the low contaminant that boils of comparing more ratios with other situation is purged from water and escapes into by the water that repeats the heating part purifying.

According to another superior notion of the present invention, the inventive method also further may further comprise the steps: after finishing repeating step, then the part of measuring in advance in the waters of purifying waste water is distilled; And collect distilled water in a collection space so that real consumption.An advantage of these characteristics is more a high proportion of low boiling and higher boiling contaminant to be removed from purify waste water and escaped to atmosphere than former.

The present invention is also at the device of purifying waste water, and this device comprises: the equipment of determining the restricted quarter; With the impure of predetermined limited quantity and water that must purifying is introduced the device of the restricted quarter; Be used to filter the water that is introduced into to obtain the device of partial purification water; In the restricted quarter, be separated out a collecting chamber so that there with the device of the form collection unit separating and purifying water in waters; The water that is used for the heating part purifying make it temperature near or reach the device of its boiling point; And be used for making the partially purified water in waters to circulate continuously, and through the device, collecting chamber and the heater that filter partially purified water is carried out further purifying, the contamination degree in water is lower than the device of predeterminated level.By above, if restriction of this device and separating device comprise a upper area and a lower area of forming collecting chamber with receiving filtration device, and be furnished with the container of the lid that is supported on the porous on the upper area that can remove, will be more favourable.Secondly, heater is included in and settles a resistance heater in the collecting chamber, make and be immersed in fully in the waters, and EGR can comprise that a steam that places heater top to be used to collect the steam that heater produces collects bell, and tedge can collect bell from steam and extend to the steam that filter is collected with conduction, and is drawn towards the water column of filter thus.By above, if if it is the filter cylinder that there is the passage of a part that receives tedge in central authorities that tedge has an outer sleeve and filter, when arriving the upper area of the restricted quarter, the collar that is linked in tedge is outer, will be favourable.

According to another characteristics of the present invention, container has an outlet in its underpart, and heater, comprise that is located at a container external heater outer and that link to each other with this outlet, and comprise that one is put at the tedge of external container and the EGR that is connected with heater, and a spout that links to each other with tedge, the spout replication points to the restricted quarter, steam that will be produced by heater and the water column of carrying steam secretly rise in tedge together, and lead to filter.Yet, if it also is favourable arranging like this, EGR comprises a tedge that extends upwardly exhibition from heater, and the spout that refers to the restricted quarter that links to each other with the upper end of tedge and return, the rising and lead to filter in pipe together of steam that this spout will be produced by heater and the water column of carrying steam secretly.It is more favourable that the structure of apparatus of the present invention becomes, because this device comprises cup-like containers (at least when the top of container is provided with lid) and this cup-like containers that is contained in container top and comprises a main part of aiming at the long-neck part of priming device and spout and holding filter, make to flow into the bottom inflow filter of the water of long-neck part from filter, and upwards after filtration the top of device flow out and overflow cup-like containers then and enter accumulating chamber.

If device of the present invention also comprises the device that flows that can interrupt the water that is cleaned in the waters selectively, perhaps be favourable, device makes the temperature of the water in the waters be increased to its boiling point and makes a part of water vapor by this, and in vaporization, finish the operation of purification, in the case, this container must be opened an outlet at least so that make the steam of generation escape into the restricted quarter thus above accumulating chamber.A device can also further be set be condensed into water, and in a collection space, collect condensed water, so that real consumption in order to drawing off steam thus.Also having in addition a bit but be not limited thereto, when condensing unit comprises a recipient that is centered around outside the container, equally also is favourable promptly.

Detailed description to most preferred embodiment:

Now in detail with reference to the accompanying drawings, at first with reference to figure 1, will find that reference number 1 is in order to mark the current that are cleaned in purifier of the present invention.Current 1 flow to a filter/clarifier filter cylinder 2 by the porous of water purification installation or the lid 3 of opening.Lid 3 be provided with hole 3a can allow current 1 to flow through or allow various steam or gaseous medium thus from the inside of water purification installation escape into device outside and enter around atmosphere.Yet, if lid design is made it and can move in the initial or water-filling stage that current 1 are introduced this device, so, will accelerate the water-filling of device, just current 1 can directly flow to filter/clarifier filter cylinder 2, and be not subjected to stopping of lid 3.

Filter/clarifier filter cylinder 2 comprises the level board 4a and the level board 4b who is positioned at the below that are positioned at than the top, and they also are bound up mutually by the leg 5 that lies around.Part 5a is stretched in the expansion of stretching of upwards expanding that the wall 5 that lies around has an expansion to extend top level board 4a top, is separated out the distribution space 5b of a water that holds the desire purification or purifying.In the incipient stage of operation, no matter whether lid 3 exists, the water of current 1 arrives distribution space 5b, enough be dispersed in equably on the cross section of filter/clarifier filter cylinder 2 thus, in distribution space 5b, build up to certain degree at this water, thereby, be directed to through the water that a place or many places water inlet are emitted by current 1 on the zone than the level board 4a of top of filter/clarifier filter cylinder 2 of separating with water inlet.Obviously, if in the initial or water-filling stage, the words that the lid 3 of perforate exists, with further improve or even finish required distribution effect separately, with regard to current 1, before current via hole 3a, basically be by the mode that shows on the figure, spread on the lid 3.Spill lid 3 for fear of water, lid 3 comprise one upwards establish enclose a 3b, it will around surround fully and form a reception space 3c who receives the water of current 1.The level board 4a and the 4b that are positioned at top and below surround an inner chamber 20 with leg 5, in establish two deposition filters respectively and put reach up the below level board 4a and 4b on, maybe can from the water that flows through, make by other material of collecting granules material by cloth, ribbon.Be clipped between two deposition filter 6a and the 6b, and occupy inner chamber 20 main volume be filter medium 7, be such as active carbon or charcoal or the material that can in the water of process, absorb or adsorb dissolved impurity known to other.Reach up and all offered porous 8a and 8b on lower horizontal plate 4a and the 4b, allow water in the purification process to make from being dispersed in space 5b respectively and enter inner chamber 20 by opening 8a and enter the accumulation space 9a of a container 9 by opening 8b thus and among accumulation space 9a, accumulated by the gravity effect.The impure water of current 1 is introduced the inside of container 9 by above-mentioned mode by filter/clarifier filter cylinder 2, until being full of 2/3rds of container 9 inside.

Bottom at the accumulation space 9a of container 9 is provided with a resistance heater 10.Be arranged on electric turn-knob switch 11b on the electric wire 11 when plug 11a inserts power supply and outwards winding, just can power by 11 pairs of resistance heaters 10 of electric wire.Resistance heater 10 fully is immersed in the waters 12 that accumulation space 9a holds.When resistance heater 10 is switched on, just the water in the waters 12 of desire purification is heated.If there is not cover lid 3 before this, must cover lid 3 on the upper flange of container 9 this moment, make and only overflow, thereby the level that this class gas medium is overflowed by cross section is reduced to required degree by the hole 3a on the lid 3 from the steam or other the gas medium of the effusion of container 9 contents.

After beginning to be heated by resistive water in 10 pairs of waters 12 of device and heating, in waters 12, particularly on resistance heater 10, begin to form water vapo(u)r bubble within a few minutes, although the water temperature as a whole in the waters 12 does not reach boiling point as yet.Temperature when resistance heater and waters 12 further rises, and water vapo(u)r bubble 13 breaks away from and rises to the waters 12 from resistance heater 10, is collected or captures by the steam gatherer of mitriform.

Steam mitriform gatherer 14 central authorities at an upper portion thereof converge into a tedge 16 of stretching to the upper edge, and the middle section that this tedge 16 passes filter/clarifier filter cylinder 2 is leaving the preset distance on the upper horizontal plate 4a of filter cylinder 2 until its terminal.Filter cylinder 2 has the inside partition wall 18 of a tubulose, is separated to form the passage of a tedge 16.There is the support ring 19 of a supporting filter device/clarifier filter cylinder 2 outside of tedge 16.Thereby apparently, filter/clarifier filter cylinder 2 is independently, and can take out from tedge 16 easily when transposing, but after the uncap 3, upwards it is proposed container 9 easily.It also is similarly easy that filter/clarifier filter cylinder 2 new or transposing is placed on the tedge 16, and the upper end of tedge 16 is penetrated the passage that is formed by partition wall 18, slides filter cylinder 2 downwards till running into support ring 19 along tedge 16 then.

After the purifier entry into service of the present invention, because near the water resistance heater 10, the temperature of the water that is cleaned near but in fact do not reach boiling point, again because the mixture of the steam of tedge 16 inside and the water carried secretly is more much lower than the proportion that places the much cold water outside tedge 16 and the steam mitriform gatherer 14, thereby, after device of the present invention begins operation, more promptly make the water that is cleaned begin in the inside of tedge 16 to rise.Thereby, the decline of the pressure of the water column that the imbalance on this proportion and the tedge that causes thus 16 are inner and outside forces colder water to move downward the inside that enters steam mitriform gatherer 14 by corresponding slotted eye 17, simultaneously, being collected in steam in the steam mitriform gatherer 14 and the above-mentioned water column of being carried secretly thus 15 rises in tedge 16.

In the process that continues heating, water column 15 clips steam and overflows or spray from the upper end of tedge 16, (even) may impact the lower surface of lid 3 major parts, there water column 15 and by steam at water that condensation on the lid 3 forms since the influence of gravity flow on the level board 4a on top of filter/clarifier filter cylinder 2, as indicated, on this level board 4a, scattered again in large quantities and flow through those openings 8a again and entered filter/clarifier filter cylinder 2, be subjected to deposition filter 6a and 6b again and be clipped in the effect of the filter medium 7 in the middle of them at there, flowed to by the influence of gravity and flow through to be arranged in the opening 8b on the lower level board 4b and to reenter waters 12.In other words, heated water sees through filter medium 7 and obtains filtering.

When behind the inner chamber 20 of opening 8b outflow filter/clarifier filter cylinder 2, the water that is cleaned flows into waters 12 and because the agitaion of heated water and mixed with the water in the waters 12 among the accumulation space 9a of container 9 with the form of water droplet 21.Then, be used for repeating in about 20 minutes time of purification run above-mentioned heating and filtration cycle several times.In other words, after the water in waters 12 was begun heating, the quantity that flows through the water of filter/clarifier filter cylinder 2 was Duoed several times than the quantity of the water in the waters 12.

After being heated by resistive about 20 minutes of device 10 heating continuously, the water that is cleaned rises by the inside of tedge 16 and then flows out through filter/clarifier filter cylinder 2 downwards, the water that is cleaned has enough detentions or time of contact in filter medium 7, has removed considerable soluble impurity in the process of the rising of repeated multiple times and the accumulation space 9a that is back to container 9 downwards.This moment, electric turn-knob switch 11b is threaded to " opening circuit " position, the water in the waters 12 that resistance heater 10 and this moment have purified just begins to cool down.Filter/clarifier filter cylinder 2 with tedge 16 and steam mitriform gatherer 14 from container 9 inner taking-ups, but just purifying waste water in the applying container 9 then.

This is understandable, and in fact all low boilings or volatile organic matter and inorganic matter are displaced and water has been purified.This is because these volatile steam and gas loose to atmosphere all around, shown in 31 by the hole 3a on the lid 3 of perforate.Trend towards being filtered the VOC of medium 7 absorption on the other hand, when the temperature of filter/clarifier filter cylinder 2 reaches about 85 to 90 ℃, promptly displaced equally 185 to 195 °F the time and loose to atmosphere.In addition can water and the moisture heat cycles of steam to the processing of filter/clarifier filter cylinder 2 to stop any bacterium on filter medium 7 or the growth of other biology.

Referring now to Fig. 2,, Fig. 2 has described the improvement structure of a purifier according to the present invention, because it is all similar in many aspects with above-mentioned structure, so will be used among Fig. 2 with in the past identical reference number, to indicate corresponding parts and only the difference in these structures at length to be pointed out at this.This improved purifier structure as discussed above, is used to produce in batches and purifies waste water.The container 9 of the water purification installation that this kind improved is built to a cylinder body shape, and tedge 16 is arranged at the outside of container 9 and links to each other with a spout 22 that stretches into the long-neck part 26 of cup-like containers 25 by a joint sleeve 24.Current 1 are imported in the long-neck part 26 of cup-like containers 25 equally when beginning or water flood operations, and the storage chamber 25a of cup-like containers 25 is full of, and the accumulation space 9a that overflows and inject container 9 at last reaches the predetermined waters 12 of level to purify waste water at this composition.In such structure, water is not inner heated at container 9.The substitute is, water places container 9 external heated devices 10 by exporting 23 inflows, and enters tedge 16 from heater 10.Heater heats water and produces steam and water column, the bottom of container 9 is heated with the water that is accumulated in the waters 12 among the 9a of space to container 9 by way of parenthesis heat simultaneously.Cup-like containers 25 is positioned in the top of container 9 inside, even the filter that wherein holds/clarifier filter cylinder 2 is not with above-mentioned just the same also similar with it.At this moment, after initial or water flood operations are finished, and after making external heater 10 connect power supply, do not draw among steam and the water column 15(figure) just from the openend ejection of spout 22, enter in the long-neck part 26 of cup-like containers 25, water is collected in this.The water that is collected, as former current 1, be to flow through filter/clarifier filter cylinder 2 from the bottom to top, water flows into the inner chamber 20 of filter cylinder 2 from the opening 8b of the lower horizontal plate 4b of filter cylinder 2, in having passed through filter medium 7 and corresponding deposition filter 6b and 6a(figure, do not draw) after, flow out inner chamber 20 by the opening 8a on the upper horizontal plate 4a of filter cylinder 2.When the water surface in the cup-like containers 25 rises, be cleaned the water that promptly is filtered and overflow the edge 28 of cup-like containers 25 and fall into waters 12 by the gravity effect, mixed with the water among the inner space 9a of container 9.

Container 9 is furnished with the lid 3 of oneself, and the hole 3a on it allows volatile steam effusion container 9 inside and enters atmosphere on every side, shown in 31.After the purification run that also comprises the repetitive cycling by tedge 16 and filter/clarifier filter cylinder 2 stopped, tap 30 that can be by being furnished with control handle 29 was easily with the discharge of purifying waste water in the waters 12.Although these differences are arranged, the method for operating of above-mentioned purifier of the present invention is the same.

Fig. 3 and Fig. 4 have disclosed the structure of the improved purifier of another kind of the present invention, are specially adapted to the ting model of this class device, and particularly those sightseeing travelers are employed.This again adopt with before identical reference digital to determine corresponding parts.For example, the container 9 of this device lid 3 that can make and on the upper end cover of its opening, have respective shapes with stainless steel.An important design feature of this improvement structure is, the parts that are necessary of this device, it is steam mitriform gatherer 14, tedge 16, cup-like containers 25, internal resistance heater 10 and filter/clarifier filter cylinder 2, be according to the mechanical mode device and be fixed on the lid 3, and/or become a global facility of lid 3.Filter cylinder 2 can take out from cup-like containers 25, thereby can replace easily after filter medium 7 exhausts.

In this special structure, the current 1 of the unboiled water of desiring to be cleaned are the inside that enters this device by the water injection hole on the lid 3 32.Filter/clarifier filter cylinder 2 and make current through herein effect such as above the explanation done of contact Fig. 2 be consistent.End at the electric wire 11 that is equipped with away from plug 11a has a subsidiary plug 33, can insert the socket 34 that is installed on the lid 3 and with heater 10 electrical communication, thereby electric energy is provided in purification run.On the other hand, when stopping using water purification installation, plug 33 can be extracted from socket 34, and electric wire or cable 11 can be ensconced in the container 9.Because this device is square and when making ting model, can be placed on easily in traveller's the bag or chest.At all other aspect with regard to the mode of operation of structure and said structure, Fig. 3 is the same with the improvement structure that Fig. 4 is described.

Making the material of each parts of purifier, as not being stainless steel, then must be material nontoxic and that be not damaged under the boiling temperature of water.Equally, when container 9 is to use resistant to elevated temperatures material, when making such as above-mentioned stainless steel, purifier of the present invention also can be operated under the situation of not having electricity, this device directly can be placed on naked light or other thermal source.

At last, Fig. 5 has described the added improvement structure of purifier of the present invention, and the water that is cleaned in a manner described experiences the last distillation stage in this device, and has only these water sides that were distilled to be used to consumption.In addition,, then indicate with identical reference number corresponding to the parts that the parts of this device had been discussed in the past, only to do not described before those or done the detailed description of making comparisons of improved part.

The structure that Fig. 5 described mainly comprises three parts, is called cold doubt/storage gatherer 35, is used for heating the container 9 of waters 12 water and lid or upper top that the mode described by Fig. 5 is installed on the heating container 9 divide 3.The impure water of predetermined quantity, for example three gallons, be to divide water injection hole 32 on 3 to enter this upper top in the mode of current 1 by upper top to divide 3 inside, furtherly, be to enter in the long-neck part 26 of the cup-like containers 25 that holds filter/clarifier filter cylinder 2 in the manner described above.Inject the water of upper top branch or lid 3, at first be downward through long-neck part 26, upwards flow through filter/clarifier filter cylinder 2 then in the mode shown in the arrow.The water that part has purified leaves after the filter cylinder 2, flows to downwards and flow through to be positioned at lid or upper top and to divide aperture 36 on 3 the base plate 37 to enter the accumulating chamber 9 of heating container 9, forms waters 12 at this.

When the water of predetermined quantity, be about three gallons at this, poured into can being called that Fig. 5 describes refilter/water purification installation of distiller after, by plug 11a and electric wire or cable 11 and power connection.Outwarding winding is installed on upper top and divides turn-knob switch 38 on 3, and rotation is installed on upper top and divides time controller 39 on 3,, is threaded to the position of " three gallons " for this example.Show that resistance heater 10 has also been begun waters 12 is heated by the logical electric current of having gone up this moment.In minutes, steam and water column 15 begin along tedge 16 risings and are put into by spout 22 in the long-neck part 26 of cup-like containers 25, this then water that was heated flows along the same approach that the impure water of putting into long-neck part 26 originally flows through, that is, flowing through filter/clarifier filter cylinder 2 control aperture 37 of flowing through then downwards enters accumulating chamber 9 and converges with the water in waters 12 again.

In the circulation by time controller 39 decisions, " refiltering " of the water within about 15 to 20 minutes in the waters 12 taken place several times.In this stage, active carbon or other active material that impure water has very big chance to be filtered in the medium 7 are handled, and the volatile vapor of various contaminants as 31 among the figure shows once more, enters by hole 3a in the air of upper top part 3 tops.

15 to 20 minutes cleansing phase at the end with the solenoid coil 40 of time controller 39 operations to control magnetic valve 41 and 42 respectively, thereby is closed spout 22 and control aperture 37 respectively.Because closing of valve, steam and water column 15 no longer along tedge 16 inner risings, can not be flowed out from spout 22.Therefore, also just no longer overflow and flows to and control aperture 37 from the edge 28 of cup-like containers 25.Yet as previously mentioned, control aperture 37 equally also is closed to prevent that water from flowing into heating container 9 again.

Yet the heating of resistance heater 10 is still being carried out, and the water in the waters 12 begins violent boiling as a result, thereby produces abundant steam.These steam are under the heating container 9 inner pressure that produce of sealing, passage 43 by the dispersion that is equipped with on heating container 9 perisporiums enters in the annular space 44 that the internal perisporium by heating container 9 periphery walls and condensation/storage gatherer 35 constitutes, be easy to condense on the perisporium of gatherer 35 at these annular space 44 steam because this perisporium by ambient air from external refrigeration.Condensed water flows into collecting chamber 45 downwards and forms the water source 46 that process purifies and distills gradually at this.

For being collected in the stage that the water in the heating container 9 distills of before having purified, continue under the control of time controller 39 that about two gallons waters in the water of original adding are evaporated, condensation and be collected in the gatherer 35 till.Use one 1,000 watt heater, the distillation stage is expended about three hours time.Condenser/storage gatherer 35 has a big vent hole 47 at least.After still-process was finished, the water that is cleaned can be emitted from collecting chamber 45 by tap 30.

Before next group water is evolved purification, to carry out a shirtsleeve operation earlier.At first, will be fixed in upper top divides various electric and other critical piece on 3 to divide 3 to mention from container 9 and shift out together with whole upper top.Then, heating container 9 and discard the contaminant water that remains in is wherein proposed.Then, again container 9 is put back to gatherer 35 and divide 3 to be placed in its top the lid or upper top.After these work were finished, this device can inject the impure water of next group again.

Hot water vapor in condenser/storage gatherer 35 can make it to be in fungi-proofing state, and by " Pasteur's moral sterilization " water that is housed in the gatherer 35 is carried out disinfection.Time in necessity only must be carried out very simple maintenance to this device, comprises at least the inner surface of heating container 9 is cleaned the incrustation scale that gathers on it to remove once in a while.According to the operating position of device and the polluting property and the degree of impure water, every replacement in some months filter/clarifier filter cylinder 2.

Purifier of the present invention, particularly the water purification cartridge that Fig. 5 described is equipped with several advantages.One, even under the smaller situation of its size because impure water is flowed through filter several times, the efficient of active carbon filter 7 improves greatly.In this way, " the detention time " of impure water in filter medium 7 is than long several times of habitual one-pass filter.In addition, in the cycling of warmed-up water about 20 minutes of this cartridge filter 2, water temperature reaches 160 °F, thereby uses active carbon filter and the bacterial reproduction problem that takes place with regard to not worrying taking place with ways customary.In addition, because heating and delay process, more volatile compound is displaced active carbon filter 7, thereby has stayed the organic compound of more space for other difficult volatilization of absorption in filter.

Because the characteristics (three critical pieces are only arranged) of structure, device of the present invention for ease of maintenaince reaches cleaning.Must not screw off or dismantle any parts.The container 9 that heats and evaporate is simple bowls, can clean easily.If necessary, can before purifying, so handle in every batch of water so that get rid of the contaminant of accumulation.Result as batch operation, because the effective catharsis before the distillation, the water that is distilled also condensation is pure especially, does not contain volatile materials and other organic matter, these organic matters must be removed it before following batch of distillation, not so will be brought into or mix the distillate that is cleaned in addition.Thereby, as seen the invention provides device a kind of integral body, that effectively utilize the space and the energy, in this device water be filtered, preliminary clearning, evaporation, condensation and preserve in the gatherer of a sterilization.In addition, the quality of the water that this device of the present invention produces is better than other any commercially available system or equipment, but only expends the sub-fraction of known system or equipment expense.With regard to the energy consumption efficiency of purifier of the present invention, it can be comparable to other distillation type clarifiers in addition.

Embodied some special constructions of purifier at this description and the purifier described, be not limited in the special construction that these are carefully stated, realized because various improvement and structural change can be considered by the present invention.Thereby protection scope of the present invention is only by attached down claims decision.
