Description
Technical field
The present invention relates to and use PTF instantaneous heater to the technological improvement product of the small-sized pure water drinking machine that For Miniature Ro Membrane (R/O film) is core filter material, belong to the manufacture field of miniature water purifier preparation field and household electrical appliance, laboratory purified water equipment series products.
Background technology
The kind of the small-sized water making machine of purifying waste water of current use R/O film is very various, and widely by universal use.But along with the universal use of this series products, the technical problem existed in currently available products also highlights gradually.One of them important problem is exactly in small-sized R/O film water purification machine, the aquifer yield of R/O film, easy cleaning, degerming be stubborn problem.Especially the problems referred to above that the small-sized R/O film water purification machine being dispersed throughout each family to some in use exists, directly affects the trust of human consumer to R/O film.Here it is by the end of so far, do not use widely and provide R/O film water purifier for oneself, but use the reason of the drummed pure water coming from concentrated water purification preparation station preparation in most of families of China.And adopt water treatment station to each family supply drummed pure water drawback be familiar with by the country of some developed regions, current development trend is not only, what be used more widely is in water-purifying machine system, do not have storage tank or the very little direct drinking water purifier of water tank volume, and end adds gentle Refrigeration Technique is also widely used in these direct drinking water purifier products, the cold water (being commonly called as frozen water) that can i.e. heatable hot water is provided to human consumer and can freeze.
But the present inventor finds after generally investigating domestic small-sized R/O membrane water purifier that is existing and external report, these small-sized R/O film water purifiers of current listing well do not solve the water yield processed of R/O film with temperature decline significantly reduction, scale removal, degerming problem, the changes in amplitude that wherein aquifer yield of R/O film is larger to remain and highlights in these small-sized R/O membrane water purifiers, this directly affects small-sized client, and especially family is that the small-sized client of unit is to the trust of R/O film water dispenser.
Summary of the invention
Talking about publicly known, is that the water yield processed of the small-sized water purifying appliance of core devices is all 25 DEG C with envrionment temperature and is as the criterion and represents for adopting R/O film.For professional, all know that the change of temperature directly affects R/O film aquifer yield, and influence coefficient is very large.The home-use R/O film that the present inventor once selected a market conventional, model is: HY1812-50, belongs to polyamide composite film, and the aquifer yield measured under 25 DEG C of conditions that this product represents is 50m
3/ d, the aquifer yield provided according to this film manufacturer and the relation of temperature, the present inventor briefly tabulate show as follows:
Table 1:R/O film temperature and actual aquifer yield relation (labelled amount is the % relative to the aquifer yield measured under 25 DEG C of conditions)
| Temperature | Temperature factor | Aquifer yield m 3/d | Relative labelled amount % | Temperature | Temperature factor | Aquifer yield m 3/d | Relative labelled amount % |
| 5℃ | 2.16 | 23.1 | 46.3％ | 10℃ | 1.77 | 28.3 | 56.5％ |
| 15℃ | 1.46 | 34.3 | 68.6％ | 20℃ | 1.21 | 41.49 | 83.0％ |
| 25℃ | 1 | 50 | 100％ | 30℃ | 0.88 | 57.0 | 114.0％ |
| 35℃ | 0.77 | 64.9 | 129.7％ | 40℃ | 0.68 | 73.4 | 146.8％ |
from table 1, when inflow temperature is at 15 DEG C, the aquifer yield of R/O film is only and indicates 83% of the water yield, and when temperature of intaking is 5 DEG C and 10 DEG C, the aquifer yield of R/O film is only equivalent to 46.3% and 56.5% of labelled amount.If this aquifer yield is for the client not possessing the basic general knowledge of R/O film, obviously cannot accepts aquifer yield and be only the real result indicating water yield half.And for the most area of China, in 1 year, there is the time water supply pipe of at least half to be transported to the water temperature of client's tap water port not at about 25 DEG C, but usually lower than this temperature, in the majority with less than 15 DEG C, do not have the house of heating installation at some, it is more general that inflow temperature maintains the phenomenon of 5 DEG C-10 DEG C.
The problem that another one highlights is after R/O film is used for some time, regardless of the prefiltration post of leading portion design how good, capital produces at the water entering surface of R/O film pollutes, and these pollutents mainly contain the metal oxide of calcium carbonate scale, calcium sulfate, barium sulfate, strontium sulfate scale, iron, manganese, aluminium etc., silicon-dioxide, colloid sediment (inorganic or inorganic/organic mixture), nature or synthesis of organic substance, biomass (biological sludge, mould or fungi) etc.When these pollutents are present in the feed-water end of R/O film, also will significantly reduce the aquifer yield of R/O film.Carefully analyze, these pollutents can be divided into two large classes, and a class is the inorganic salt of insoluble, and another kind of is colloid group.
3rd problem highlighted is microbiological contamination problem.Water inlet due to R/O film is generally that city tap-water supplies water, and along with the growth of duration of service, microbial contamination also can be gathered in the influent side of R/O film, forms above-mentioned micelle pollutent.
Current R/O membrane water purifier manufacturer gives a lot of cleaning methods, and conventional is the method adopting special-purpose medicaments washing.The medicine that some film manufacturers and water dispenser manufacturer can both provide some special to client, but because the client of small-sized R/O film water dispenser disperses very much, the after sale service of China is difficult to follow-up, even if so there is good existing method, is also difficult to universal enforcement or generally accepted by human consumer and correctly apply.This situation is in some developed countries, the method solved is adopted to be that the selling price that R/O membrane water purifier producer provides is higher, manufacturer has the ability to provide free after sale service of visiting under the support of high price, when R/O film water dispenser uses to a certain degree, manufacturer can also reclaim, user is part payment purchase commodity again, and manufacturer will provide a new R/O membrane water purifier that is new or upgrading to client.This service mode is based upon the acceptance that country that social prestige system height perfects could obtain human consumer.The quality of current China water-purifying machine product is stable not, business reputation is also in the stage of gradual perfection, the general phychology of client takes notice of the pursuit to outward appearance, and the technology of inherence is not known much have less understanding quarter, often easily go to pursue and the more cheap water-purifying machine product of price, so the sales mode of this water-purifying machine of developed country is difficult to reference to imitating in society instantly of China.
PTF is the abbreviation of polymer thick film, and the moment solvent heater adopting PTF to make at present is commonly used.The sharpest edges of PTF moment heat-producing machine are that volume is little and heating efficiency is high.
Current PTF moment heat-producing machine has been widely used in R/O membrane water purifier; but unfortunately be the PTF moment use of heat-producing machine on R/O water-purifying machine be used to the pure water through R/O membrane reverse osmosis is heated for drinking hot water at stream R/O film below, and do not consider and use PTF moment heat-producing machine to go increase the water efficiency processed of R/O film and R/O film carried out to the cleaning of protectiveness.
First key element of the present invention is exactly the water purifier using PTF moment heat-producing machine to increase R/O membrane efficiency, it is characterized in that position that PTF moment heat-producing machine assembly installs in the flow path system structure of water-purifying machine is after booster water pump, before R/O film.In the structure of this flow path system, first advantage of installing heat-producing machine before R/O film can guarantee that R/O film has good aquifer yield after water temperature promotes, especially when water temperature is lower than the occasion of 20 DEG C, promoting water temperature is the method guaranteeing that R/O film aquifer yield is the most simple and efficient.Second advantage is the insoluble inorganic salt dirt be deposited on for some after promoting water temperature in R/O, and high water temperature will be conducive to dissolving and loosening these inorganic salt, and impel it to excrete out from dense water end (W.E.) mouth.3rd advantage is that for some, the colloid dirt be deposited in R/O film plays well dissolving and loosens effect after lifting water temperature, and impels it to excrete out from dense water end (W.E.) mouth.4th advantage is that especially water temperature reaches more than 55 DEG C, will very be unfavorable for the breeding of bacterium and mould, and high water temperature will impel it to excrete out from dense water end (W.E.) mouth after lifting water temp.If certainly higher temperature, more will be conducive to the lifting of bacteria-eliminating efficacy.
In the water-purifying machine system of R/O film, only see large-scale water manufacturing system and have the phenomenon heating assembly in the leading portion stream of R/O, do not see in the water-purifying machine of small-sized, especially home-use small-sized R/O film in the stream before R/O film and the phenomenon heating assembly is installed.Small-sized R/O film mentioned here refers to that the water yield processed is at 5000m
3the water-purifying machine water manufacturing system of the R/O film of/below d, also comprising can overall (or a whole set of) R/O film water manufacturing system of transporting.Because PTF moment heat-producing machine is the energy-conservation rapid heating assembly just risen in recent years, so more do not see in the stream before R/O film the phenomenon being provided with PTF moment heat-producing machine in small-sized R/O membrane water purifier, therefore the talent of the present invention proposes the application of this patent as core technology.Therefore, compared with technical characteristic of the present invention is to form structure with the stream of traditional R/O film pure water water-producing apparatus, between booster water pump and R/O film, PTF moment heat-producing machine is installed, and under the intelligent control of microprocessor, the temperature entering R/O film water temperature can be changed as required.
With this, there is distinctive flow passage structure, can by Fig. 1,2,3, the flow passage structure of 4 makes the function of whole water purifier system more perfect.Fig. 1,2,3, the detailed description of 4 states further by specific embodiment below.
In the flow passage structure of R/O film water purifier of the present invention, R/O film can be in parallel use when combining, also can be that series connection uses, also can with the strainer of other type, such as, form parallel connection or series model together with gac class filter material post, resin anion(R.A), resin cation (R.C.) and the mixed bed resin column combination that is jointly made up of resin anion(R.A) and resin cation (R.C.).
In the flow passage structure of water purifier of the present invention, booster water pump is had to be absolutely necessary, but before should be noted that the position of booster water pump must be placed in PTF moment heat-producing machine, this is because when PTF moment, water temperature increased too high by heat-producing machine, the work of overheated water temperature to booster water pump is unfavorable, even can damage booster water pump, and after PTF moment heat-producing machine is placed in booster water pump and before R/O film, would not occur because water temperature over-high damages the phenomenon of booster water pump.In addition, if when booster water pump one is not enough to the requirement meeting flow, adopt more than one booster water pump, in parallel use is Normal practice, but need to propose, booster water pump preferably uses intelligent control device microcontroller to carry out intelligentized control method, and the object of intelligentized control method is carried out without steps control to flow, to obtain suitable flow, this is also important technology feature of the present invention.
In the flow passage structure of R/O film water purifier of the present invention, before booster water pump, design initial filter post is basic protection to R/O film.In fact initial filter post is exactly the different strainer of pore size, and material can be multiple material, and object is the molecule that filtered image silt etc. is difficult to melt.Initial filter post can be the arbitrary combination of many, but the initial filter post after the second stage of initial filter post can be resin anion(R.A) or resin cation (R.C.) or their mixed bed resin filter material post.Some zwitterions can be adsorbed like this, better protection can be played to R/O film.
Current embedded microprocessor is used by Rapid Popularization in various electrical equipment, especially various electrical equipment can be made to have better intelligent functions with the low price of 32-bit microprocessor, reduce power consumption and high arithmetic speed.Therefore the design proposes to use microprocessor to carry out intelligentized control method especially.Microprocessor can with 8,16 and 32 and 64, but according to present technology popularity rate, use 32-bit microprocessor to be first-selected, this is also important technology feature of the present invention.
After using intelligent control device microcontroller in systems in which, just after initial filter post, before booster water pump, turbidity transducer should be settled, resistivity or specific conductivity detecting sensor are installed after R/O film.So just effectively can monitor the performance of initial filter post and R/O film, user can be reminded in time to change Filter column or R/O film when the performance of Filter column and R/O is bad, this is also important technology feature of the present invention.

Last point it should be noted that Controlling System of the present invention adopts micro-chip to carry out intelligentized control method.
Distinguishing feature in above-mentioned water-purifying machine stream added PTF moment heat-producing machine exactly before R/O film, and its objective is and the water temperature entering R/O promoted as required, this effect has following benefit:
First can guarantee that R/O film has good aquifer yield after water temperature promotes, and especially when water temperature is lower than the occasion of 20 DEG C, promoting water temperature is the method guaranteeing that R/O film aquifer yield is the most simple and efficient.
Second advantage is the insoluble inorganic salt dirt be deposited on for some after promoting water temperature in R/O, and high water temperature will be conducive to dissolving and loosening these inorganic salt, and impel it to excrete out from dense water end (W.E.) mouth.
3rd advantage is that for some, the colloid dirt be deposited in R/O film plays well dissolving and loosens effect after lifting water temperature, and impels it to excrete out from dense water end (W.E.) mouth.
4th advantage is that especially water temperature reaches more than 55 DEG C, will very be unfavorable for the breeding of bacterium and mould, and high water temperature will impel it to excrete out from dense water end (W.E.) mouth after lifting water temp.If certainly higher temperature, more will be conducive to the lifting of bacteria-eliminating efficacy.
Select suitable voltage control that PTF moment heat-producing machine can be made effectively water temperature figure to be herein raised to the critical temperature of boiling, and produce water vapor phenomenon, and constantly carry the effect of new head water power at booster water pump under, the stream rearwards high-temperature water steam flow that provides water and steam gas to mix thus, this state will have more effective effect to the dirt removed on R/O film.
So in the operation of water purifier of the present invention in reality, how to grasp the temperature of PTF moment heat-producing machine herein? the instruction of the workbook of general R/O is that the use temperature of R/O film is all expressed as less than 50 DEG C, but the present inventor obtains following simple data after to related data inquiry:
Table 2: the related data of the maximum operation (service) temperature of some R/O mould materials
Although the data in upper table can not the thermostability situation of the overall R/O of letter lid, but it is or being exactly that R/O works when the temperature of 50 DEG C to an information of contriver is there is not any problem from table, at short notice, paper mould material itself has better high thermal resistance, and temperature can reach more than 100 DEG C without any problem!
Self-designed a set of R/O film pure water system is had in the laboratory of the present inventor's work.Four R/O films that the R/O film used is certain producer's model is HY1812-50, two strings two also connect use.In order to solve the water yield processed in temperature low season, the researchist of the present inventor adds small-sized Haier's hot water bag at the water intake end of system, when water temperature lower (about 15 DEG C), water inlet is heated, and the top temperature (being about 75 DEG C-85 DEG C) inflow temperature being risen to hot water bag of stage, first water inlet at such a temperature arrives the temperature of R/O film at 50 DEG C about-60 DEG C after 3 grades of initial filtrator coolings, we are water processed at this temperature, continuous use for many years, R/O film still remains good, and effluent quality does not significantly decrease.We are also once in the summer that temperature is high, by the temperature increase of hot water bag to the highest (temperature arriving R/O film is about 70 DEG C-80 DEG C), and maintain about 30min for removing the dirt of R/O film.The result of use of method in our laboratory of this scale removal of heating is fine, adds the work-ing life of HY1812-50 greatly.
By the application practice to the temperature analysis above mould material and the present inventor, the present inventor draws 2 conclusions: first is that between 45 DEG C-50 DEG C, water processed uses is feasible for the R/O film of no matter what material.Second point is that to bear down at 10min-30min the temperature being greater than about 60 DEG C during this period of time be also feasible to the R/O film of no matter what material, even within the shorter time, the temperature of such as, bearing 100 DEG C within 10min is also feasible, because the fail temperature of the material of all maskings is all higher than 110 DEG C in table two.
Above-mentioned two conclusions are very important, because in the present invention, contriver can use the PTF moment heat-producing machine and in conjunction with the intelligent control system of the present invention to system be placed in before R/O film, make the function that water purifier of the present invention is implemented below automatically:
(1) by PTF moment heat-producing machine temperature increase to 45 DEG C-60 DEG C, R/O film is less than to hot water temperature's cleaning of 30min time period, or by the vaporization temperature of the temperature increase of PTF moment heat-producing machine to 100 DEG C, and under the promotion of booster water pump, high-temperature evaporation water R/O film being implemented to below the 10min time period rinses.Because these two functions can in the execution of intelligentized Controlling System Program, such as repeatedly interval performs, need not perform time of water processed at night.Adopt and can carry out respond well cleaning to the dirt of R/O film and microbiological contamination in this way, and significantly reduce conventional liquid medicine cleaning, even do not use.The present inventor adopts in the R/O film water manufacturing system of similar approach in the laboratory of the present inventor, substantially abandons the matting of liquid medicine for many years, and the R/O film used still has good water-based energy processed, and water quality meets the requirements.
(2) PTF instantaneous heater is used to promote temperature to cold water in water temperature before R/O film lower than 18 DEG C or 15 DEG C (selecting different temperature according to power conservation requirement and water producing cost analysis), such as rise to 25 DEG C or higher temperature (selecting different but still suggestion lower than 45 DEG C according to power conservation requirement and water producing cost analysis), guarantee the water yield processed of R/O film.This method also can in the execution of intelligentized Controlling System Program, even also can PTF moment heat-producing machine before flowpath segment in, increase and inflow temperature is detected to the temperature sensor of water temperature, and set warm temperature with this, automatically performed according to setting selection by intelligentized Controlling System.
Based on above-mentioned statement, the water-purifying machine of the present invention's design, should the R/O film of the good heat resistance such as polyimide, polysulfones of first-selected great thermotolerance when selection R/O film, but does not get rid of and use cellulose acetate class R/O film.Because although the heatproof condition of cellulose acetate class R/O film is slightly lower, its temperature tolerance substantially can meet to adopt in method of the present invention to rinse between the high temperature, short time of R/O film.
In the system of this example, it is the single-chip computer control system of core that intelligent control system have selected Kinetis E02 series 32 bit CPU microprocessor chips.The function of Kinetis E02 series 32 bit CPUs is very powerful.Therefore under the control of Kinetis E02 series 32 chips; before R/O, use PTF instantaneous heater to carry out regular Thermal protection cleaning and Warm status operation to R/O film, effectively can solve water yield Yin Wendu processed in current small-sized R/O film water purifier and decline and the problem of decline and dirt immune.If control temperature setting is suitable, under the control of Kinetis E02 series 32 chips, effectively can guarantee that the long-term good of water-purifying machine of the present invention runs, and significantly can promote the work-ing life of R/O film.So water-purifying machine of the present invention adopts intelligentized electrical equipment control, its object is exactly wish to have intellectuality, the heated wash of sequencing and water function processed.If increase photoelectricity Turbidity measurement sensor after initial filter post, after R/O film, increase resistivity or conductivity sensor, just can be implemented in the function of line primary filter and R/O film replacing prompting.Increase magnetic valve at water receiving port, and place water receiving container, just can realize unmanned water function processed.Etc., under these intelligentized state of a controls, more harmonious man/machine cooperation function can be provided.
Certainly, the intelligentized control method of water-purifying machine system of the present invention also can select 8 or 16 and even 64-bit microprocessor chip, also logic programming controller (PLC) assembly can be selected to carry out the control of functionalization, and these changes all belong to the ABC category of professional skill field.Water-purifying machine system of the present invention can also increase some interesting functions easily on the basis having intelligentized control method, such as, play music, give the correct time, warning etc., to strengthen its amusement and other practicality.Because as class household electrical appliance, after giving these subsidiary functions, will more be subject to the favor of human consumer.
Embodiment 2 Fig. 2 and Fig. 3 shows in the small-sized water manufacturing system of R/O film, in other two kinds of small-sized R/O film waterworkss of carrying out the change of filter membrane filter material below of PTF moment heat-producing machine, this waterworks can be applied to as test water in laboratory, and simultaneously also can the daily drinking-water of battle support laboratory personnel.
In fig. 2, except different in place below and Fig. 1, the implication of remaining icon is all identical with the implication in Fig. 1.The icon do not existed together is described below:
Fig. 2-8 is anions and canons mixed with resin bed filters.The system of Fig. 2 and the systematic differences of Fig. 1 are in the system of figure 2, and two R/O films are used by parallel connection and change over series connection use, form two-stage R/O membrane reverse osmosis system.One-level zwitterion mixed bed column is added between two-stage R/O system, its effect is after first step R/O film is pure by water, send into second stage R/O film again after using zwitterion mixed with resin column to remove the metal ion of trace further and carry out micro-filtration, and carry out On-Line Dynamic Monitoring by resistivity (or specific conductivity) electrode detection sensor (Fig. 2-18) and go out resistivity of water (or specific conductivity), the high-resistance ultrapure water of use for laboratory is obtained with the resistance (reduction specific conductivity) improving pure water further.Zwitterion mixed with resin bed Filter column is installed in before R/O film in many systems, and a lot of occasion becomes post to use respectively resin anion(R.A) and resin cation (R.C.).Generally adopt the reason of this using method to be that the price of R/O film is in early days very expensive, the price of resin is then relatively cheap, and the effect using resin column to remove zwitterion before R/O film is the load reducing R/O film, protection R/O film.And R/O film has been popularized now, price has had very greatly different decline, and the price of anions and canons resin column then maintains change not quite substantially.For the zwitterion mixed with resin column that efficiency is higher, its price is relatively costly, and does not use high performance yin, yang mixed with resin post to be just difficult to obtain the high resistivity (10 of laboratory needs
16Ω) water.So after high performance yin, yang mixed with resin column has been placed on first step R/O film by the present invention, and accept the pure water of the high resistivity after yin, yang mixed with resin column at this opening (Fig. 2-16).In order to get rid of the potential trace organic substance of yin, yang mixed with resin column, after secondary R/O film post is placed on yin, yang mixed with resin column, can retain the potential micro-content organism impurity that may occur, thus obtain more highly purified use for laboratory water.Still the cold or hot high-purity water that refrigerator (Fig. 2-10) and PTF moment heat-producing machine (Fig. 2-11) instantaneously provide experiment for laboratory and drink is installed additional after secondary R/O film.In the flow path designs of Fig. 2, do not design activated carbon column, be not that native system does not need activated carbon column, is actually and can adds activated carbon column as required, and the position of interpolation can in the stream after Fig. 2-6PTF moment heat-producing machine Anywhere.
In the system design of Fig. 2, be the increase in water turbidity photoelectric testing sensor (Fig. 2-17) and high-purity water resistivity (or specific conductivity) electrode detection sensor (Fig. 2-18) different significantly on the other hand from Fig. 1 designed system, be respectively used to judge the replacing construction of primary filter assembly and the quality of high purity water.
The integral position of cooling assembly and second PTF moment heat-producing machine moves forward after first step R/O film by embodiment 3 in the system of figure 3, and the reason so changed is exactly strengthen the function of lab assistant drinking-water.Because generally, common drinking water is by just reaching the purification purity of potable water guidelines again by one-level R/O membrane ultrafiltration after coarse filtration.Not only there is the water inlet of Fig. 3-16 in figure 3, after the R/O of the second stage, also adding the water inlet (Fig. 3-23) that connects higher more pure water, for meeting the requirements at the higher level of laboratory to water quality.
The implication of all icons is all identical with the implication of embodiment 1,2 in figure 3, as space is limited go to live in the household of one's in-laws on getting married, just there is no need to introduce one by one more herein, can be just very clear for the mark of embodiment 1,2.
Embodiment 4 Fig. 4 adds the zwitterion mixed with resin post recycle system on the basis of Fig. 3.Because in practice, zwitterion mixed with resin post after a certain period of use time column efficiency can decline, the deionization ability of zwitterion mixed with resin post can decrease, cause resistivity of water can be in underproof criticality, and now zwitterion mixed with resin post does not damage, do not need to upgrade immediately yet.Solution is carrying out repeatedly deionization through zwitterion mixed with resin post and exchange high purity water iterative cycles, and like this after repeatedly deionization exchanges, resistivity of water will raise, and reaches requirement.
The principle of work of zwitterion mixed with resin post part in embodiment 4 is expressed as follows:
Water cleaning systems is if there is undesirable in the resistivity at high resistivity water inlet (Fig. 4-23) place, and the circulation water program that the intelligent control system of this water-purifying machine starts zwitterion mixed with resin post by presetting parameter improves resistivity of water further.After entering this program, first electronic venting valve (Fig. 4-31) will open to water tank (Fig. 4-29) inner filling water by program, closes electronic purging valve (Fig. 4-31) after being full of water.Then first booster water pump (Fig. 4-5) work is stopped, start second booster water pump (Fig. 4-28), now magnetic valve (Fig. 4-24, Fig. 4-25, Fig. 4-26) cuts out, magnetic valve (Fig. 4-27, Fig. 4-30) is opened, water in water tank (Fig. 4-29) circulates in water tank (Fig. 4-29), booster water pump (Fig. 4-28), zwitterion mixed with resin post (Fig. 4-8) and second stage R/O film (Fig. 4-7), and carries out on-line monitoring by resistivity (or specific conductivity) electrode detection sensor (Fig. 4-18).(10 are generally when the resistivity of water in water tank reaches requirement
16time Ω), the intellectualizing system alarm of equipment.If now need water receiving, then open electronic venting valve (Fig. 4-30) and magnetic valve (Fig. 4-24), shut electromagnetic valve (Fig. 4-30), by booster water pump (Fig. 4-28), the high-purity water exclusion in storage tank (Fig. 4-29) is flowed out via valve (Fig. 4-23).
When above-mentioned cycle operation, magnetic valve (Fig. 4-25) cuts out by system, actual effect is closed by the concentrated water spout of second stage R/O film, and the water so just forcing two stage supercharging water pump (Fig. 4-28) to pump all is flowed out by the water purification mouth of second stage R/O film (Fig. 4-7).The object done like this is because the water in storage tank has been through the high-purity water of two-stage R/O film preparation, the impurity of these water is metal ions of extremely trace, if so the dense water end (W.E.) mouth of open second stage R/O, then have part water to drain through concentrated water spout, this is unfortunately, has therefore installed magnetic valve herein to ensure that the high-purity water in storage tank is unlikely to loss.In practice, moment of discontinuity can open this magnetic valve (Fig. 4-25) and abandon a part of high purity water on a small quantity, be useful to the protection of second stage R/O film like this.
