Description
Technical field
The present invention relates to a kind of commercial water machine, belong to water electrolysis equipment technical field.
Background technology
Water is Source of life.Be accompanied by the aggravation of social progress and environmental pollution, people (comprise resident living water to daily water consumption, the process waters such as medicinal water, cosmetic water and making food, etc.) especially the water quality of domestic water more and more higher He more and more diversified demand is proposed.
The common people's daily life water being provided by municipal administration, even if dispatch from the factory in waterworks, water quality safety index is substantially up to standard, is transported to " water,tap " of common people's water terminal, due to following reason, also oneself a kind of through becoming (special) micro-polluted water:
1) water environment pollution goes from bad to worse, and existing waterworks treatment process is outmoded, and the water quality of dispatching from the factory has been difficult to (particularly the in the situation that of burst water hygiene event) up to standard;
2) secondary pollution that water transfer pipe network system is brought;
3) in water, chlorine residue and residual organic matter interact, and may generate the new objectionable impurities that do not have in the water of source (for example strong carcinogen trichloromethane, etc.).
Therefore, be to ensure being perfectly safe of drinking-water, be necessary water,tap purifying treatment more in addition.In office space, people more and more process water,tap by commercial water machine.Commercial water machine in the market generally has two kinds: 1) adopt the water purification treatment technology that ultra-filtration membrane is main body, effluent index should be not less than national < < CJ-1994_1999 > > direct-drinking purified water standard; 2) adopt reverse osmosis membrane water technology, obtain being commonly called as the high purification drinking-water into " pure water ".First water after commercial affairs water machine purifies deliver to water butt, then supply water to each drinking-water terminating set (so-called drinking-water terminal, reality is exactly the little water pot with well heater) through pipeline.But pipeline drinking-water system can bring secondary pollution, can grow a large amount of bacteriums, tend to make bacterium to exceed standard, particularly stagnate and for example supply water, after for some time (Holidays), in water, even there will be peculiar smell; And current commercial water machine can not be removed the toxic byproduct that in tap water, chlorine residue and residual organic matter interact and produce.
For solving the bacterial contamination of above-mentioned occasion, various sterilising method have been developed at present, wherein more effectively electrolysis or electric-field sterilizing, ozone sterilization etc.Yet, the common problem that the sterilization modes such as existing electrolysis or electric-field sterilizing, ozone exist is, the oxidation factor producing in water is often without what select, and intensity is restive, easily produces toxic side effect (for example improper strong carcinogen---the bromate that very easily generates of ozonization).Therefore,, in order to ensure the safe drinking water of commercial water machine, be necessary the bubbler of commercial water machine and the drinking-water terminal that connects by pipeline to carry out further purifying water process.
Summary of the invention
The technical problem that the present invention solves is: propose a kind of can generation in water for killing the oxidation factor of water bacterium, and can effectively control the commercial water machine of type and the quantity of oxidation factor, this water machine can be produced and be rich in drinkable water active hydrogen, suboxide reduction potential.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of commercial water machine, comprise main frame and drinking-water terminal, and described main frame comprises water purifier and the water storage container being communicated with described water purifier, described drinking-water terminal is provided with water tank, and described water tank is connected with water storage container; In described water storage container, be provided with the first sterilizing unit, in described water tank, be provided with the second sterilizing unit, described the first sterilizing unit and the second sterilizing unit include at least one pair of negative electrode and positive electrode and for the electrolysis power to described negative electrode and positive electrode power supply; Between paired negative electrode and positive electrode, be provided with water-permeable barrier film, described water-permeable barrier film covers on positive electrode, and the spacing δ scope of described water-permeable barrier film and negative electrode is 0≤δ≤10 millimeter.
Water-permeable barrier film of the present invention is also water permeable membrane, refers to that permeable aperture is from grade to nano level, comprises the various filtering membranes that daily water treatment is used, as: ultra-filtration membrane (UF), nanofiltration membrane (NF) and microfiltration membrane (MF), etc.
The barrier film of water-permeable described in technique scheme covers on positive electrode, refers between water-permeable barrier film and positive electrode it is zero spacing substantially.
The disclosed technical scheme working mechanism of the invention described above application is presented below:
The ionic membrane of the barrier film of water-permeable described in the present invention unconventional employing, but in water electrolysis field unused a kind of barrier film, the inventor innovates ground this water-permeable barrier film is introduced in apparatus for electrolyzing as the interelectrode barrier film of yin, yang.
Normal reaction to water electrolysis is, cathode hydrogen evolution (gas), Oxygen anodic evolution (gas), H
+ion trend cathode zone, and OH
-ion tends to anode region.In the present invention, between yin, yang electrode, be provided with water-permeable barrier film, electrolyzer is divided into cathode compartment and two of anolyte compartments reaction compartment.
Because water-permeable barrier film covers on positive electrode, be equivalent to volume=0, anolyte compartment, the covering that Oxygen anodic evolution reacts because of barrier film antianode is interfered.The H generating in Anodic Desorption Study conversion reaction
2o and the oxygen of separating out at anode, owing to discharging nowhere, can only, after having overcome the permeable water resistance of water-permeable barrier film, move to cathode compartment through countless micro channels in barrier film.
In the present invention, the countless micropore water storage spaces of barrier film, are equivalent to the resistance of minute water one by one parallel with one another in yin, yang electrolysis current path.Because spacing δ between negative electrode and film is very little, the pressure drop of cathode compartment water resistance is negligible, and additional electrolysis voltage Main Function is on water-permeable barrier film, and in each micropore, unit voltage intensity is high.Add the permeable aperture very little (micron order and even nano level) of water-permeable barrier film, the high-energy electron discharging from negative electrode is intensive micropore, is equivalent to a large discharge electrode (negative electrode) to be decomposed into numerous small curvature radius electrode.Therefore, not only in water-permeable barrier film micropore, to water electrolysis redox reaction, can fully carry out, from anode, move to the O in fenestra
2be subject to bombardment and the highfield effect of high-energy electron to generate oxygen bubbles, and excite chain reaction, bring out water body self gasification, in micropore, form the plasma discharge of continous-stable, generate a large amount of oxidation factor, finally by cathode zone, be diffused in vessel water.
Comprehensive above-mentioned reaction process is known, and the present invention arranges water-permeable barrier film by innovation between yin, yang electrode, and the spacing that this water-permeable barrier film is covered to anode and controls water-permeable barrier film and negative electrode, and the direct effect of bringing is:
1) the present invention not only can produce and obtain the low water good for health that is rich in hydrogen of redox potential, also generates considerable strong oxidation factor in water simultaneously, and than other existing rich hydrogen water preparation technique, bactericidal purifying ability promotes greatly;
2) water-permeable barrier film conventionally can very thin (for example the thickness of ultra-filtration membrane can be accomplished 0.1mm～0.5mm), between anode and cathode, adding after barrier film, can be by the stable thickness range that substantially equals barrier film that remains on of spacing between anodic-cathodic, electrolysis voltage under Condition such as Gong such as Tong Deng can be very low, even only with a 3.7V lithium battery power supply, can form 2 amperes of above working currents, prior art cannot be accomplished; Add plasma discharge highly effective reaction factor occurring in film etc., actual power loss of the present invention is reduced greatly than similar commercial water machine.When coated carbon material anode, also can effectively prevent from that carbon granule from peeling off to cause short circuit.
In the present invention, the permeable pore size of water-permeable barrier film further affects the effect that the present invention processes water.Permeable aperture is little, and to analyse the inhibition of oxygen gasification reaction good for antianode, and the radius-of-curvature that permeable aperture reduces to be equivalent to discharge electrode reduces, and is also conducive to the carrying out of plasma discharge; But permeable aperture is too small, antianode is analysed oxygen gasification reaction and is suppressed excessively, to be equivalent to increase substantially Oxygen anodic evolution current potential, adds outside in the situation that electrolysis voltage is constant, Faradaic current between anode and cathode declines greatly, causes on the contrary various reactions desired in the present invention not carry out.In addition, the many factors such as physical strength of film are selected to be also associated with in the permeable hole footpath of film.Repetition test in practice, considers according to different water demands, and the present invention selects the pore diameter range of water permeable membrane from 2 millimeters to 1 nanometer, contains the conventional ultra-filtration membrane of daily life water treatment, nanofiltration membrane and microfiltration membrane.That is the improvement of the invention described above technical scheme is: the permeable aperture of described water-permeable barrier film is less than or equal to 2 millimeters and be more than or equal to 1 nanometer.

By above-mentioned technical solution of the present invention improved to one, can be when guaranteeing normal evolving hydrogen reaction, again objectionable impurities in water is adsorbed onto and in activated charcoal membrane, carries out oxidative degradation, and the oxidizing substance in inhibition water is unlikely to too many, prevent Biological indicators variation, be especially applicable to processing take the Living Water that " drink " be object.Further, if water-permeable barrier film is superimposion at least two layers of forming, and wherein one deck water-permeable barrier film near positive electrode has electroconductibility and micron order aperture (being for example to be made by electroconductibility pottery or activated carbon fiber), will bring further following variation:
1) because have a satisfactory electrical conductivity, the volts lost itself producing is very little, has therefore guaranteed that the electric discharge of water ionic medium still mainly carries out in relying on the water permeable membrane (being typically chosen in ultra-filtration membrane) non-conductive, that permeable aperture is less of negative electrode one side.
2) due to the porousness of medium, can strengthen the inhibition that antianode is analysed oxygen on the one hand, pollutent in the water of source can be adsorbed in the hole of electroconductibility pottery or activated carbon fiber on the other hand, be subject to the direct oxidation of anode and indirect oxidation effect and degree of depth degraded is removed.
3) residual chlorine residue in tap water is had to fine absorption, and be converted into harmless chlorion under anodize, greatly reduce the danger that residual chlorine residue in water may generate toxic byproduct.
The concrete covering of water-permeable barrier film and positive electrode can be all surfaces that covers positive electrode, can be also the part surface that covers positive electrode; When covering the part surface of positive electrode, preferably cover the surface (being also principal reaction face) of relative negative electrode one side of positive electrode.
