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 is through becoming one (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.).Especially, the toxic byproduct that above-mentioned chlorine residue causes, uses such as simple method boiled water can not be removed.
Therefore, be to ensure being perfectly safe of drinking-water, be necessary in addition purifying treatment again of water,tap.Conventionally it is believed that by boiled tap water drinking be the simple approach that ensures safe drinking water.In fact, boiling tap water is drunk and is not represented safety, because water boil can not " kill " heavy metal, arsenide, prussiate, nitrite, organic pollutant (such as objectionable impuritiess such as agricultural chemicals, sterilant, synthetic detergents), in tap water, poisonous carcinogenss such as generating haloform, halogen acetic acid is reacted in residual chlorine residue meeting with humic acids, fulvic acid etc. in the water of source, and heat-processed can be accelerated its generation.
The electrolysis water cup of publicity patented technology is non-isolating film structure at present, as a kind of reductive water diaphragm-free electrolytic water tumbler of patent No. ZL201020582802.5, by adopting activated carbon anode and metallic cathode pair, utilize the potent adsorption of activated carbon anode, part imbalance while producing water electrolysis under redox reaction population equilibrium, produces and obtains required reductive water.Its advantage is splendid to effects of purification quality, and shortcoming is that nano ceramics (the high-specific surface area activated carbon block of phase technique sintering in the middle of adopting) is high to manufacturing technique requirent, and for high rigidity tap water, after water processed, pH may exceed 8.5.For another example a kind of diaphragm-free electrolysis water tumbler processed that is rich in negative hydrogen ion water of producing of patent No. ZL201120509347.0, take the plate inner wall of titanium base material inert anode member and cup that the gap that a δ scope is 5mm >=δ > 0 is set, its water making machine reason is the difference that while utilizing under Weak current water electrolysis, mass transfer reaction lags behind electrochemical reaction.The advantage of this electrolysis water cup is that after having avoided water processed, pH may exceed 8.5, and shortcoming is not as front one to water purification effect.Above-mentioned two kinds of electrolysis water cups common problem be that water power dissipation ratio processed is higher.
Summary of the invention
The technical problem that the present invention solves is: propose a kind ofly can produce the electrolysis cup that is rich in active hydrogen, has the suitable water of drinking of 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 electrolysis cup, and comprise electrolysis power and be provided with negative electrode and the inner bag of positive electrode, described positive electrode, negative electrode connect respectively the positive and negative electrode of electrolysis power; Between described negative electrode and positive electrode, be provided with water-permeable barrier film, described water-permeable barrier film is close on described positive electrode, and the spacing δ scope of described water-permeable barrier film and described 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 electrolysis cup 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.
1) the spacing δ of water-permeable barrier film and negative electrode is greater than zero, and cathode compartment volume is greater than zero, and cathode hydrogen evolution reaction is normally carried out, and generates hydrogen, and the redox potential of cathode compartment and then whole vessel water declines

Because water-permeable barrier film covers on positive electrode, be equivalent to volume=0, anolyte compartment, Oxygen anodic evolution reaction is interfered because of the covering of barrier film antianode.The H generating in Anodic Desorption Study conversion reaction
2o and the oxygen of separating out at anode, owing to discharging nowhere, can only overcome after the permeable water resistance of water-permeable barrier film, moves to cathode compartment through countless micro channels in barrier film.
3), 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, can fully carry out water electrolysis redox reaction, move to the O in fenestra from anode
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, be finally diffused in vessel water by cathode zone.
Comprehensive above-mentioned reaction process is known, and the present invention arranges water-permeable barrier film by innovation between yin, yang electrode, and this water-permeable barrier film is covered to anode and controls the spacing of 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 (thickness of for example ultra-filtration membrane can be accomplished 0.1mm～0.5mm), between anode and cathode, adding after barrier film, can be by stable spacing between the anodic-cathodic thickness range that substantially equals barrier film that remains on, 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 electrolysis cup.In the time of coated carbon material anode, also can effectively prevent from that carbon granule from peeling off to cause short circuit.
3) by suitable selection and adjustment to barrier film and electrode proterties etc., can control the generation of the water oxygen factor, to adapt to the drinking-water demand of different occasions.
In the present invention, the permeable pore size of water-permeable barrier film further affects the present invention processes the effect of 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 is 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.
As preferred scheme, described positive electrode is arranged at inner side of liner bottom, and described inner bag is as negative electrode.The more compact structure of electrolysis cup like this.

By above-mentioned technical solution of the present invention improved to one, can be in ensureing normal evolving hydrogen reaction, again objectionable impurities in water is adsorbed onto and in activated charcoal membrane, carries out oxidative degradation, and oxidizing substance in inhibition water is unlikely to too many, prevent Biological indicators variation, be especially applicable to the Living Water taking " drink " as object to process.Further, if water-permeable barrier film is superimposion at least two layers of forming, and wherein there is electroconductibility and micron order aperture (being for example to be made by electroconductibility pottery or activated carbon fiber) near one deck water-permeable barrier film of positive electrode, will bring further following variation:
1) because have a satisfactory electrical conductivity, the volts lost itself producing is very little, has therefore ensured that water ionic medium electric discharge still mainly carries out in the water permeable membrane (being typically chosen in ultra-filtration membrane) non-conductive, that permeable aperture is less that relies on negative electrode one side.
2) due to the porousness of medium, on the one hand can strengthen antianode and analyse the inhibition of oxygen, 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 residual chlorine residue in water and may generate the danger of 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; In the time 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.
The invention described above technical scheme improves three: in described negative electrode, have the first through hole, the aperture of described the first through hole is more than or equal to 1 millimeter.By such improvement, can be conducive to cathodic reaction and more fully carry out, and the bubble hydrogen that region between negative electrode and barrier film is produced is better derived.
The invention described above technical scheme improves four: on described water-permeable barrier film, have the second through hole, the aperture of described the second through hole is greater than 2 millimeters.On water-permeable barrier film, have the second through hole, essence be equivalent to generation one by one without film electrolysis zonule, be equivalent in other words introduce superposeed conventional without film electrolytic reaction, can appropriate change water treatment effect of the present invention, for example adjust the pH value of water etc.The permeable hole difference of the second through hole and water-permeable barrier film is: permeable hole is that the barrier film self of buying is intrinsic, and the second through hole is to make separately in addition.
The invention described above technical scheme improves five: the spacing δ of described negative electrode and water-permeable barrier film is 0 millimeter, described water-permeable barrier film is three layers of water-permeable barrier film that superimposion forms, offer one near one deck water-permeable barrier film of negative electrode and ranked first waist through hole, in described negative electrode, have one and ranked second waist through hole, described the first waist through hole and the mutual square crossing of the second waist through hole.Further, described negative electrode, positive electrode and three layers of water-permeable barrier film are arranged in the opening box of insulation, described negative electrode is located at the opening part of opening box, described positive electrode is provided with the conductive lever that passes described opening box bottom, described positive electrode is arranged on inner bag bottom by conductive lever, and described positive electrode is connected with the positive pole of electrolysis power by conductive lever.
