Description
Technical field
This utility model relates to a kind of simple desk type water dispenser, belongs to drinking water terminal water treatment technical field.
Background technology
Currently, water environment is exacerbated, drinking water quality safe and sanitary Frequent Accidents, the most seriously jeopardizes the existence of people.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 ".
Domestic and international most of waterworks the most still uses the outmoded process of precipitation, filtration, chlorination, 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 can produce 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 goes, 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 the highest.
Existing purification of water quality product or drinking water related product, predominantly medium adsorb or use the filter membrane in various aperture that the nuisance in water is intercepted the physics mode process technique 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 the most serious source water pollutes, existing physics mode processes technique and the most far from can guarantee that water quality reaching standard.But physics mode water treatment technology also has an advantage in that, it is simply that toxic byproduct will not be generated.The water quality that the most traditional RO membrane reverse osmosis filter method produces is the safest, but then it is up to the most more converse dense water of 40%-70% by exchanged for the cost that ensures safety be wasted and enter sewer pipe, cause huge water resource and waste of energy, and the cost changed after the blocking of RO film is the highest.For reducing or even reaching no effuent discharge, saving water resource, have been developed that various patented technology so far.Such as, converse dense water is stored it use, or the pollutant in dense water are first filtered Posterior circle reuse through molecular sieve etc., or adjust waste water ratio, or reduce cleaning blowing time by electrical control, or dilute in non-return valve is directly returned from water main line, or with " the double water of double films " pattern, water quality based water utilization, etc..The common deficiency of these technology, one is not consider from overall system design, and simply the single measure in local, often makes system overall work unbalance；It two is all not consider that the water inlet operating mode from improving membrane component is started with, and alleviates the workload of membrane component, it may be said that be " curing the symptoms, not the disease ", so the product that yet there are no real utility goods so far comes out.
Comparatively speaking, although Water Treatment technique has the plurality of advantages such as the most efficient, it it is a kind of excellent advanced oxidation processes, but itself there is series of problems in electrochemical treatments, occasion should not be processed at civilian terminal Drinking Water to be used alone, there is not yet so far and close extensively application at daily life Large Water Treatment Field.Tracing it to its cause, one is that Water Treatment technique needs the enough response time, and in daily life water occasion, water purifier is from start to the water outlet only several seconds, and pollutant time of staying in water purifier is the shortest, has had little time related chemistry reaction treatment at all；It two is that Water Treatment technique is likely with certain toxic and side effects.Such as, although chemical oxidation reaction technique 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 is generated are substantially non-selectivity, uncontrollable, producing, if dealing with improperly, the novel substance not having in the water of source most probably, jeopardizing safe drinking water on the contrary；Just because of this, processing occasion at common people's daily life drink water purifying, the application for Water Treatment technique can be described as double cautious.
But, in today that the unprecedented severe contamination of water environment, conventional physical water purifier are the most unable to do what one wishes, again the probability that Water Treatment is applied is paid close attention in close examination in Drinking Water purified treatment, it is ensured that people's life drinking water quality safety, is of great practical significance.

This utility model to solve technical problem is that: provides a kind of and does not produce toxic byproduct and the water dispenser of reliable operation length in service life while antibacterial in reducing hardness of water, degraded Organic substance in water, inactivation water.
In order to solve above-mentioned technical problem, the technical scheme that the utility model proposes is: a kind of simple desk type water dispenser, including electrolysis cells and film unit；Described electrolysis cells includes the paired electrode of negative and positive, for the electrolysis power of described electrode power supply and water tank, described water tank is provided with the first water inlet and the first outlet；It is two right that described paired anodic-cathodic has, the first electrode respectively to and the second electrode pair, the first water penetration barrier film that non-conducting material is made it is provided with between the yin, yang electrode of described first electrode pair, the second water penetration barrier film that non-conducting material is made it is provided with between the yin, yang electrode of described second electrode pair, the anelectrode of the first electrode pair is completely cut off by described first water penetration barrier film with water tank, the negative electrode of the second electrode pair is separated by described second water penetration barrier film with water tank, and the negative electrode of described first electrode pair and the anelectrode of the second electrode pair are respectively positioned in water tank；Described membrane filter unit is provided with the second water inlet and the second outlet, described first outlet and the connection of the second water inlet；In use, the negative electrode of described first electrode pair all directly contacts with the water in water tank with the anelectrode of the second electrode pair, the anelectrode of described first electrode pair is only contacted with the infiltration water oozed out by described first water penetration barrier film in water tank, and the negative electrode of described second electrode pair is only contacted with the infiltration water oozed out by described second water penetration barrier film in water tank.
It should be noted that, this utility model process to seeming city for tap water, as described in the background art, water pollutes the most serious now, city has become as a kind of micro-polluted water (or perhaps special contamination water) for tap water, and its polluter includes environmental pollution (such as pesticide residues etc.), the pollution of chlorination generation and pipeline secondary pollution etc..
The preferred micro-filtrate membrane filtration unit of membrane filter unit described in this utility model, ultrafiltration membrance filter unit or nanofiltration membrane unit.
Working mechanism of the present utility model and the beneficial effect brought are presented below.
Described water tank is with first, second water penetration barrier film for boundary: described first electrode is to setting up separately in the first water penetration barrier film both sides, and the negative electrode of described first electrode pair is in water tank, and its anelectrode is outside water tank；Described second electrode is to setting up separately in the second water penetration barrier film both sides, and the anelectrode of described second electrode pair is in water tank, and its negative electrode is outside water tank.Certainly, being provided with cavity as inside water tank, the first or second water penetration barrier film is arranged on cavity housing, then the negative electrode of the second electrode pair being arranged in cavity or the anelectrode of the first electrode pair are considered as being arranged on outside water tank.
First by the first electrode to as a example by, the anelectrode of the first electrode pair only contacts (anelectrode does not directly contact with the water of water tank) with the infiltration water penetrating through the first water penetration barrier film in water tank, anode direct oxidation reaction is transferred to carry out outside water tank, reaction product of anode is drained outside container, will not return again to container internal contamination water quality.Meanwhile, negative pollutant such as chlorine residue, the various harmful anions etc. in water, by anode voltage effect, it is also possible to through the first water penetration barrier film water in container, moves to water tank outer with infiltration water discharge.
In this utility model, the structure of the first water penetration barrier film shows as the aquaporin region excessively of countless permeable micropore on microcosmic, owing to the first water penetration barrier film is that non-conductive material is made, thus in the aquaporin excessively of permeable micropore, produce voltage drop, i.e. after the decomposition voltage of electrolysis power puts on external electrode (anelectrode) and interior electrode (negative electrode), form following voltage landing relation: the outer anelectrode of the first water penetration barrier film (+) the voltage drop U3 of the anti-generation of water resistance between negative electrode in pressure drop U2 → the first water penetration barrier film that between → anelectrode and the first water penetration barrier film, the voltage drop U1 of moisture film → water penetration barrier film direct impedance produces and water tank.
nullAnd the anelectrode of the first electrode pair only infiltration water with the first water penetration barrier film contacts，The anelectrode of the first electrode pair presses close to the first water penetration barrier film，So liberation of hydrogen during electrolysis、The gas that oxygen evolution reaction generates easily enters crossing of permeable micropore and generates bubble in the water in aquaporin and in crossing aquaporin，In the narrow and small environment crossed in aquaporin of the permeable micropore of the first water penetration barrier film, bubble is easy to broken thus produces localized hyperthermia's high pressure，And then inspire efficient water body plasma discharge with minimum voltage，In the first water penetration barrier film and in the first water penetration barrier film neighboring area water, (plasma is and solid-state the plasma of generation hydroxyl free base class transient state oxidation factor、Liquid、Gaseous state is in material the 4th state of same level，Low temperature plasma is rich in electronics、Ion、Free radical and excited state molecule,Electronics and ion have the highest reactivity,The chemical reaction being difficult under usual conditions or speed is difficult to can be made to become the rapidest，Plasma group is generated by water body electric discharge，The degradation efficiency of pollutant in water body can be greatly improved)，The oxidisability of this hydroxyl radical free radical transient state oxidation factor is extremely strong (exceeding ozone)，The existence time in water is the most extremely short simultaneously，Therefore water can be reduced directly to after rapidly the pollutant such as Organic substance in water (such as antibacterial) being formed extremely strong Degradation self rapid oxidation after generation，Do not stay any toxic and side effects.
Second electrode pair with the first electrode to similar, but voltage landing in opposite direction.The most same, in this utility model, the negative electrode of the second electrode pair contacts with the infiltration water of the second water penetration barrier film and is to ensure that the cell reaction of the second electrode pair is normally carried out, it is possible to produce great amount of hydroxy group radical type transient state oxidation factor.
Meanwhile, under the effect of the second electrode pair, the metal cation etc. such as calcium ions and magnesium ions in the endogenous water of water tank, ferrimanganic persistently separates out, and discharges through the second water penetration barrier film so that the hardness continuous decrease of Water in Water Tanks, in the water of source, harmful heavy metal etc. are progressively removed；And based on the direct oxidation effect of the anode of the second electrode pair in water tank, the microorganism in the water of source is inactivated, and Organic substance is degraded.
It addition, anelectrode equivalence the 3rd group of electrode of composition of the negative electrode of the first electrode pair and the second electrode pair is to (without barrier film between yin, yang electrode), the microorganism in the water of source is made to be inactivated under its electric field action, it is possible to more preferably to play the purification of electrochemistry.
This utility model is in use, first source water carry out electrochemical treatments through described electrolysis cells, by calcium ions and magnesium ions in the water of source, ferrimanganic and the chlorate of strong oxidizing property, hypochlorite is discharged from water tank, and by hydroxyl free base class transient state oxidation factor, source water is sterilized and organic matter degradation, then intercept through the further physics of described membrane filter unit and filter residual harmful substance in water (toxic byproduct is only a small amount of H2O2 and O3, the half life of decomposition of H2O2 and O3 is usually no more than half an hour, not only the filter assemblies of rear end or absorbent module will not be produced harmful effect, and filter assembly or absorbent module can be carried out sterilizing), thus obtain the purification water of the degree of depth.This utility model uses the combination of " preposition electrochemical treatments and membrane filtration postpositive disposal ", thus overcome in background technology the various defects (the easy broken invalid of filter membrane mentioned in such as prior art, heavy metals exceeding standard etc.) of the combination of " the preposition process of physical absorption-membrane filtration and electrolysis water unit postpositive disposal ", obtain required pure water.
In this utility model, membrane filter unit is pure physical treatment mode, ensure that the tight security of effluent quality especially Biological indicators, and the pollutant in the water of this utility model source are to enter before membrane filter unit basic handling clean, therefore the workload of membrane filter unit alleviates significantly, correspondingly, the service life of membrane filter unit is greatly prolonged, the effect that reaches to take stopgap measures and effect a permanent cure (service life length and the purification water water quality of generation good).
Obtaining the clamping protection of paired electrode due to first, second water penetration barrier film in this utility model, test proves, first, second water penetration barrier film in use will not be scrapped because of premature failure such as breakage or obstructions, remains reliable and stable duty；Even if occasionally having fouling at first, second water penetration barrier film and electrode surface is also scum loosely, the decomposition voltage polarity of the paired electrode being applied to first, second water penetration barrier film both sides is suitably switched, it is possible to remove the deposition fouling at electrode and water penetration membrane surface of the anions and canons precipitate easily in electrolytic process.
This utility model is when implementing; according to actual needs the polarity of two electrodes pair periodically can also be swung to; now electric pressure can also differ; so that first, second water penetration barrier film replaces degradation of organic substances, discharges harmful heavy metal ions; or discharge residual chlorine residue, various harmful anions etc., the most not only can improve the quality purifying water further, give full play to the purification of electrochemistry; and first, second water penetration barrier film can be protected, extend its service life.
In order to improve plasma discharge characteristic in film further, described first water penetration barrier film and the second water penetration barrier film can be made all to use hydrophilic barrier film.Hydrophilic film surface can form hydrogen bond ordered structure with water, can improve fenestra water-filling wet face state, and beneficially in film, plasma discharge process is persistently carried out.
Preferably, pore size and the shape of the permeable micropore of described first water penetration barrier film are essentially identical, and pore size and the shape of the permeable micropore of described second water penetration barrier film are the most essentially identical.
In this utility model, if the permeable aperture of first, second water penetration barrier film excessive (i.e. microporous space is excessive) is equivalent in a disguised form to increase electrode diameter (electrode curvature radius) and causes discharge in water to initiate excitation voltage to increase, and make generation bubble volume become to reduce greatly the catalytic specific surface area of gas-liquid two-phase.And the permeable aperture of first, second water penetration barrier film if too small (i.e. microporous space is too small), electrolysis aerogenesis can be made to occur or gas producing efficiency is extremely low, little the point discharge of numerous little radius of curvature electrode in each micropore can be caused in barrier film to a certain extent to be normally carried out.Therefore, through the repetition test of utility model people, determine that the permeable pore diameter range of first, second water penetration barrier film is less than equal to 2 millimeters and more than or equal to 1 nanometer.
The shape uniformity of membrane micropore and the uniformity of pore size are the biggest on plasma discharge impact in film.Hydroxyl radical free radical plasma group is generated, it is preferred that in use, each permeable micropore of described first water penetration barrier film and the second water penetration barrier film is respectively formed plasma discharge in order to the most more.So when using electric discharge, direction of an electric field between anodic-cathodic can be through the plasma group of each permeable micropore, carry out in plasma discharge is directed to all aquaporins excessively of water penetration barrier film, thus water body plasma discharge can be inspired with minimum voltage, the transient state oxidation factor of a large amount of great sterilizing ability is generated in water, the degradation efficiency of pollutant in water body can be greatly improved, preferably carry out sterilizing etc..
More preferable hydrophilic can be made it have by barrier film is modified, and the aperture size of micropore is uniform, concrete modified technique can use known to physically or chemically Technology, the such as shaping of fenestra Regularization, optically catalytic TiO 2, the narrowest high-voltage pulse to film pretreatment, etc..Its meaning is not only in that the raising of efficiency, also effectively prevent the deterioration being easily caused biological index because electric current density is excessive.In this utility model the first water penetration barrier film and the second water penetration barrier film preferably employ following method of modifying prepare barrier film:
