Description
Technical field
The present invention relates to a kind of purifying kettle, belong to the water quality advanced processing technology field of Drinking Water。
Background technology
Water pollutes the pollutant mainly produced by mankind's activity to be caused, and it includes industrial pollution source, agricultural pollution source and domestic pollution source three parts。Increasingly the water aggravated pollutes, and the living safety of the mankind is constituted significant threat, becomes the major obstacles of human health, economy and social sustainable development。Investigating according to authoritative institution of the world, annual at least cause global 200d 00,000 people dead because drinking unhygienic water, therefore, water pollution is referred to as " world's number one killer "。Currently, water environment exacerbated, seriously threat to life continuity, especially when burst natural and man-made calamities more so。Poor and backward area, drink is even close to luxury to clean relieved water for general public。If with means simple, cheap, efficient, the common people can be made all can to drink clean relieved water, when for how immeasurable beneficence！
Domestic and international most of waterworks still adopts the outmoded process of precipitation, filtration, chlorination so far, and river or subsoil water are simply processed into drinkable water。But, in the face of trade effluent, rural sewage and sanitary sewage wildness are spread unchecked and poured in life water source, waterworks can't bear the heavy load helpless。Adding tap water and arrive, through water transfer pipe network and high-rise storage tank, the additional pollution that drinking water terminal is brought from water factory, municipal tap water dare not say it is health。Especially, although tap water chlorination can effectively kill except pathogenic bacteria, but also producing more halogenated hydrocarbon compound, the content of these chlorinated organics is multiplied, and is the significant source causing the mankind to suffer from various disease simultaneously。Even boiling tap water, what above-mentioned residue still drove does not go, and the carcinogens such as nitrite and chloroform also can be made to increase。That is, even if the safety coefficient of drinking water is also not high。
Since directly drinking public water supply is difficult to ensure safety, water purifier arises at the historic moment, and becomes common people's hard requirement。But, existing with city for tap water be source water purification of water quality product or drinking water related product, essentially medium absorption or adopt various bore filter film that water pollutant is intercepted the physical treatment technology filtered。Owing to activated carbon class adsorbing material is easy to saturated inefficacy, and various filter membrane is easy to be contaminated by bacterial or Organic substance blocks or damaged, and therefore practical situation is can not accomplish water pollutant as desired by Design Theory sufficiently cleaned up。In the face of day by day serious source, water pollutes, existing with medium absorption or adopt various bore filter film that water pollutant is intercepted the physics mode water treatment technology filtered far to have can guarantee that water quality reaching standard。It addition, traditional RO membrane reverse osmosis filter method is very serious to the waste of water resource, often purifies 1 liter of pure water and be accomplished by discharging 3 liters of concentration waste water。But, physics mode water treatment technology also has its points of course: generally do not generate toxic byproduct。
Comparatively speaking, though Water Treatment technique has the plurality of advantages such as cheap simply efficient, and it is unsuitable for civilian terminal Drinking Water field。Trace it to its cause, one is that Water Treatment technique needs enough response time, and in daily life water occasion, and water purifier is from start water inlet to water outlet only several seconds or even shorter, pollutant time of staying in water purifier is too short, has had little time related chemistry reaction treatment at all；It two is that Water Treatment technique is generally with certain toxic and side effects。Such as, although chemical oxidation reaction can potent inactivation of bacterial, depth degradation Organic substance, remove the various harmful substances in water, but all kinds of Strong oxdiative factors that chemical oxidization method generates are substantially non-selectivity, uncontrollable, generating, if dealing with improperly, the novel substance even strong carcinogen not having in the water of source most probably, jeopardizing safe drinking water on the contrary。And reduction reaction controls the improper Similar Problems that also brings along, for instance nitrate is likely to be converted into strong carcinogen nitrite；Just because of this, have no so far in the drinking-water terminal popularization and application of Drinking Water purified treatment field especially family。
Fortunately, in daily life, drinking water needs often has at times, the feature of interval。Such as, family's three meals water and bathing peak are concentrated mainly on time morning, noon and afternoon；Wash water is then by all/time calculating。Drinking water storage device in daily life, logical refers to the drinking water terminal with storage tank (tank, container), for instance: 1) pipeline water cleaning systems end wall on-hook, desk-top or vertical drinking；2) RO water purification machine water outlet pressure store bucket (case), and watered glass for drinking, kettle；3) elevated tank that public supply mains skyscraper top layer is installed, even urban residents' groundwater abstraction is to the water tank on roof。The common problem that such system exists at present is that in storage tank, in water, bacterial micro-organism exceeds standard, and has a strong impact on water quality even abnormal flavour smelly。The solution that there is no so far。
Therefore, it is badly in need of developing a kind of use home terminal tap water, home terminal tap water is carried out deep purifying process with intermittent duty, the purifying kettle that every household is all afforded to use。
Summary of the invention
Present invention solves the technical problem that and be, not enough for prior art, it is proposed to a kind of purifying kettle less producing toxic byproduct when the home terminal in kettle is drunk water and carried out degraded Organic substance in water。
Applicant is through repetition test and explores for many years, it is found that electrochemistry is as a kind of advanced oxidation water treatment technology, attached poison seondary effect is little far beyond conventional chemical water treatment technology, and electrochemistry water treatment technology can be carried out intensive treatment intensity by the adjustment of electrical quantity and reduce the response time。So, electrochemical water treatment technology has and overcomes physics water treatment technology weakness, can be used for certain potentiality of Drinking Water purified treatment。
Electrochemical water treatment technology is to make polluter Direct Electrochemistry reaction occur on electrode or utilize electrode surface to produce strong oxidizing property active substance generation oxidation reaction and be converted. electrochemical techniques and be aided with the group technology of other high-level oxidation technologies, it is called electrochemical system, including electrode electro-catalysis, electricity-Fenton, electricity-O3, sound-electric, optical-electronic etc.。
Electro-chemical water processes and be unable to do without electrode effect, is specifically divided into electrode direct reaction and electrode indirect reaction。Electrode direct reaction refers to that pollutant are directly oxidated or reduced on electrode and remove from water。Direct Electrolysis can be divided into anodic process and cathodic process。Anodic process is exactly the material that pollutant change into the less material of toxicity or easily biological-degradable in anode surface oxidation, even occurs Organic substance inorganization, thus reaching to cut down, remove the purpose of pollutant。Cathodic process is exactly that pollutant are removed in cathode surface reduction。
Electrode indirect reaction be then the redox materials utilizing electrochemistry to produce as reactant or catalyst, make pollutant change into the material that toxicity is less。Anode indirect reaction, in water, produced redox materials, generally includes following a few class: (1) has the chlorate of strong oxidizing property, hypochlorite etc.；Elecrtonegativity, it is possible to removed by anode；(2) H2O2、O3The Strong oxdiative factors such as (standard electrode EMF 2.07, half-life 30-60min)；(3) electrochemical reaction produces strong oxidizing property and life-span extremely short intermediate, including e (solvated electron), OH, HO2·、·O2Deng free radical, based on OH, it is possible to degradation of organic substances。
But, electrochemical nature still belongs to chemical treatment technology, even toxic and side effects is little again, still has the risk of the Biological indicators reduction making water。At the unprecedented severe contamination of water environment, in conventional physical water purifier today unable to do what one wishes, again the probability that close examination research Water Treatment especially electrochemical water treatment technology is applied in Drinking Water purified treatment, a kind of electrochemical treatments technique that can efficiently remove water pollutant, again non-toxic by-products of innovative development or even electrochemistry water treatment technology work in coordination with brand-new method for purifying water and the device of coupling with physisorptive filter technique, are of great practical significance。
In order to solve above-mentioned technical problem, the present inventor proposes following technical scheme on the basis of above-mentioned cognition: a kind of purifying kettle, including at least one pair of anodic-cathodic, the electrolysis power powered for described anodic-cathodic and kettle, water penetration barrier film it is provided with between paired negative electrode and anelectrode, described water penetration barrier film is the water penetration barrier film that non-conductive material is made, described water penetration barrier film has the permeable micropore of uniform pore size, described anelectrode and water penetration barrier film are packaged into an integral unit by insulating frame, described integral unit is fixed in the pot lid of described kettle, described integral unit bottom is immersed in the water in described kettle, described negative electrode is located at the bottom in the kettle body of described kettle, in use, described anelectrode is only contacted by the infiltration water of described water penetration barrier film infiltration with in described kettle body。
It should be noted that, apparatus of the present invention process to seem home terminal drinking-water, it is usually city for tap water, as described in the background art, present water pollutes day by day serious, home terminal drinking-water has become as a kind of micro-polluted water (or perhaps special contamination water), its polluter includes environmental pollution (such as pesticide residues etc.), chlorination produces pollution and pipeline secondary pollution etc.。
Working mechanism and the beneficial effect of purifying kettle technical scheme disclosed in the invention described above are presented below。
Apparatus of the present invention architectural feature is, referring to Fig. 1, with water penetration barrier film for boundary, set up the anodic-cathodic pair in the upper and lower both sides of water penetration barrier film separately: anelectrode and water penetration barrier film are packaged into an integral unit by insulating frame, integral unit is fixed in the pot lid of kettle, integral unit bottom is immersed in the water in kettle, and negative electrode is located at the bottom in the kettle body of kettle。
Put on external electrode (anelectrode) and interior electrode (negative electrode) when the decomposition voltage of electrolysis power after, form following voltage landing relation:
The outer anelectrode of film (+) the pressure drop U3 of the anti-generation of water resistance between negative electrode in → pressure drop U2 → water penetration barrier film that between anelectrode and film, the voltage drop U1 of moisture film → water penetration barrier film direct impedance produces and container (kettle body of kettle)。
First, anelectrode and the water penetration barrier film of apparatus of the present invention are packaged into an integral unit by insulating frame, simultaneously, the anelectrode of apparatus of the present invention is only contacted with the infiltration water permeated by water penetration barrier film in kettle body, ensureing on the basis that the cell reaction of apparatus of the present invention is normally carried out, anode direct oxidation reaction being transferred to and carries out outside container, reaction product of anode is drained outside container, will not return again to container internal contamination water quality。Meanwhile, the negative pollutant such as chlorine residue etc. in water, by anode voltage effect, it is also possible to through water penetration barrier film water in container, moves to the outer anode region of container。
It needs to be noted: anode direct oxidation reaction is not need not, but anode reaction product (such as ozone) is likely to produce toxic and side effects, some toxicity still it is likely to be of by anode direct oxidation reaction product including negative pollutant, anode is arranged external container by the present invention, and above-mentioned toxic byproduct is directly with regard to outer row；And give source water electrolysis product on anelectrode such as oxygen, ozone, chlorine etc. and discharge space greatly, outside can be passed through directly emit, barrier film will not be passed through and return again to the water quality in container internal contamination container, will not remain in container in water, thus significantly reducing the toxic and side effects of above-mentioned Strong oxdiative thing。

Traditional water body plasma discharge technology, for producing water body plasma discharge, often through outside to importing gas in water, and imposes and adds high intensity pulses voltage or hot conditions。Plasma discharge is then directed to the countless small water storage space of water penetration barrier film and carries out by the present invention, rely on anelectrode to water electrolysis liberation of hydrogen, the gas that oxygen evolution reaction generates, it is partially in film and brings out water body self gasification (owing to anelectrode contacts with the infiltration water penetrating through water penetration barrier film in container, so, anelectrode presses close to water penetration barrier film, the oxygen of anode reaction etc. are easily accessible membrane micropore and generate bubble in millipore water, in the narrow and small environment of membrane micropore, bubble breaking produces localized hyperthermia's high pressure), and then inspire efficient water body plasma discharge with minimum voltage, water generates hydroxyl free base class transient state oxidation factor, the oxidisability extremely strong (exceeding ozone) of this hydroxyl radical free radical transient state oxidation factor existence time in water simultaneously is extremely short again, therefore after rapidly the pollutant such as Organic substance in water (such as antibacterial) can being formed extremely strong Degradation self rapid oxidation after generation, direct-reduction is water, do not stay any toxic and side effects。
Owing to conventional chemical water treatment technology is when purified treatment common people's daily life drinking water, generate all kinds of Strong oxdiative factors be substantially non-selectivity, uncontrollable, jeopardize safe drinking water, the strong carcinogen nitrite etc. that reduction reaction generates, processes occasion suitable for application in common people's daily life drink water purifying。Therefore, current conditions and conventional thinking limit the application in common people's daily life drinking water of the Water Treatment technique。The uncontrollable of all kinds of Strong oxdiative factors that Conventional electrochemical water is generated by the present invention becomes controlled, the present invention utilizes these characteristics of hydroxy radical just, for city for this special micro-polluted water water quality characteristics of tap water, by ingehious design in structure, the outside generation being on the one hand drawn out in container by anode direct oxidation reaction water, gets rid of oxidation reaction toxic byproduct。On the other hand anode indirect oxidation effect is performed to ultimate attainment, it is achieved the purification to its degree of depth of source water electrode and safety！
The purifying kettle technical scheme summarizing the invention described above provides the benefit that: 1) make full use of electrochemical water treatment technology, to reach existing physics water treatment technology and be unable to reach, to the depth degradation of source water pollutant, the effect efficiently removed, it is drawn out to outside device by anode direct oxidation reaction to carry out, ozone is suppressed to generate, to reduce the risk generating toxic byproduct in container in water；2) rely primarily on hydroxy kind strong oxidizing property and the life-span is extremely short and the indirect electrochemical intermediate that has no side effect, realize desired electro-chemical water treatment effect；3) the source water in kettle body remains chlorine residue and various harmful anion face south electrode transfer, pass water penetration barrier film and enter between anelectrode and film water body and discharge；4) microorganism in water in kettle body, is inactivated by the electric field action of U3 between the negative electrode in water penetration barrier film and container；5) by water-in-kettle matter deep purifying, it is ensured that safe drinking water, and simple in construction, realization are conveniently。
