Description
Technical field
The present invention relates to a kind of central water purifier, be specially one and be arranged on middle-size and small-size user (such as family, villa etc.) and register one's residence the quality purifying device for water of total water inlet end, belong to the water quality advanced processing technology field of Drinking Water。
Background technology
Currently, water environment exacerbated, but domestic and international most of waterworks still adopts the outmoded process of precipitation, filtration, chlorination so far, river or subsoil water is simply processed。But, in the face of trade effluent, rural sewage and sanitary sewage wildness are spread unchecked and poured in life water source and cause the primary pollution at water source, waterworks can't bear the heavy load helpless。
Cholorination is that China continues to use for many years and still commonly used disinfection of tap water technology, plays a key effect for microorganism in Inactivation in Water, virus bacterium etc.。Water must keep when standard-required city of native land man arrives Drinking Water for Residents terminal for tap water appropriate chlorine residue。This is not only as reducing city for tap water secondary pollution in water transfer pipe network course of conveying, be also after preventing city from arriving Drinking Water for Residents terminal for tap water in family's drinking water pipeline system it may happen that microorganism, virus bacterium " polluting for three times " (note: " polluting for three times " is the proper noun that the present invention creates for sake of convenience)。
Unfortunately, recent two decades carrys out people and finds gradually, and simultaneously, chlorine also can react a series of disinfection byproduct (DBP) of generation (strong carcinogen) with the Organic substance in water to cholorination, is broadly divided into: (1) volatility halogenated organic matters。Mainly there is haloform class, including chloroform, a bromodichloromethane, dibromo monochloro methane and bromofom；(2) non-volatile halogenated organic matters。Mainly there is halogenated acetic acids class, such as monoxone, dichloroacetic acid, trichloroacetic acid, bromoacetic acid, dibromoacetic acid, tribromoacetic acid, bromochloro-acetic acid, dibromo chloroacetic acid, Dichloro-monobromo acetic acid etc.；In addition with halogenated aldehyde, halogenated phenols, halo nitrile, halogenated ketone, halogenated hydroxyl furanone (4-dichloromethyl-5-hydroxyl-2 (5 hydrogen) furan as chloro-in 3-is called for short MX) etc., health is constituted the potential danger side of body。It addition, chlorine is almost whole absorption by human body skin, long-term bathing chlorinated water, it is easy to bring out various skin disease or even cancer。Therefore, considering from health perspectives, first chlorine residue in water should thoroughly be removed after arriving Drinking Water for Residents terminal for tap water by city, and its usual way is to install central water purifier at total water inlet end of registering one's residence。
The central water purifier of early stage is only the filtrates such as filled stone sand, activated carbon, naked eyes visible in water is removed, simultaneously chlorine residue in absorption water, except color deodorization。But along with the enhancing that water supply quality severe exacerbation and common people's drinking water safety are realized, the purification of water quality performance requirement of central water purifier is more and more higher, structure also becomes increasingly complex, cause that equipment manufacturing cost and water producing cost are more and more expensive, also bring resource unnecessary consumption (such as, in domestic water, flushing water occupy total Water consume considerable part, domestic waste water can be utilized completely), Frequent Troubles, maintenance difficulties strengthen。But the most basic still: after chlorine residue is removed, how preventing from being likely in household drinking water pipe-line system the microorganism, the virus bacterium " polluting for three times " that grow, there is not yet any solution so far, in other words, such central water purifier not yet occurs。
Another problem of domestic water is hardness of water。So-called hardness of water refers to the summation of polyvalent cation quantity in water, it is common that refer to the content of calcium in water, magnesium ion。Drinking-water hardness height is also closely bound up with health。The health problem the closest with drinking-water hardness relation is cardiovascular disease, and hard water is also easily caused by urinary system calculus。Except on healthy impact, hardness of water is too high, can bring many-sided adverse effect to daily life。As made tea with hard water, tea can be made spoiled；In order to cooking food, nutritive value can be reduced；In order to do washing, soap consumption can be increased, and affect color and luster and the flexibility of yarn fabric；Hard water boils, meeting sediment incrustation in kettle and boiler, thus increasing fuel consumption, and easily makes compromised container, etc.。
Existing central water purifier is substantially free of water softening ability, and the Main Means being intended to solve the water hardness in current family is to buy the water softening device based on ion (resin) switching technology。Its subject matter is, softened water is only used for washing, should not drink。Because in ion exchange removing water while calcium ions and magnesium ions, discharging a large amount of sodium ion, unfavorable health in water。And, water softening device through customary salt (sodium chloride) backwash, need to be wasted time and energy expensive。
Summary of the invention
The invention solves the problems that and technical problem is that: a kind of microorganism that can stop household drinking water pipe-line system and virus bacterium etc. " polluting for three times " are provided and the central water purifier reducing hardness of water can be improved。
In order to solve above-mentioned technical problem, the technical scheme that the present invention proposes is: a kind of central water purifier, including pressure resistant vessel, paired negative electrode and anelectrode, the electrolysis power powered for paired negative electrode and anelectrode, described pressure resistant vessel includes the metal cylinder being vertically arranged and the insulated enclosure end cap being arranged on described metal cylinder two ends；Being provided with the insulating spacer pipe that the end cap with metal cylinder two ends is all tightly connected in described pressure resistant vessel, have some permeable holes in the middle part of described insulating spacer pipe, described negative electrode is arranged on the bottom of insulating spacer pipe；Described insulating spacer pipe is outwards enclosed with the first water penetration barrier film and the second water penetration barrier film successively, physical absorption filter element, the barrier film that described first water penetration barrier film and the second water penetration barrier film all adopt non-conducting material to make it is filled with between described first water penetration barrier film and the second water penetration barrier film；The end cap at described metal cylinder top is provided with sewage outlet, and the end cap bottom described metal cylinder is provided with water inlet, is provided with outlet between described second water penetration barrier film and metal cylinder；Described metal cylinder electrically connects with negative electrode。
The filter element that the preferred PP cotton of heretofore described physical absorption filter element, porous ceramic micro filter material, granular active carbon, sintering activity charcoal or NACF are made。
Apparatus of the present invention work process and purification mechanism illustrate as follows:
When, in sewage outlet closedown situation, city enters into apparatus of the present invention for tap water source water from water inlet, after following multiple purifying processes, supply water to whole family pipe-line system from outlet。
(1) anelectrode at insulating spacer inner axial tube two ends and negative electrode constitute one without membrane electrolytic cell。City enters apparatus of the present invention without membrane electrolytic cell for tap water source water from water inlet, source pollutant in water is directly oxidated or reduced on electrode and removes from water, or utilize redox materials that electrochemistry produces as reactant or catalyst, make pollutant change into the material that toxicity is less。Yin, yang inter-electrode voltage field and electrolytic electrophoresis comprehensive function, will be in microorganism in the water in electric field, pathogenic bacterium inactivation。
(2) above-mentioned without membrane electrolytic cell is set to anelectrode upper, negative electrode under, the mainly cathode reaction hydrogen product of leading reaction。Owing to hydrogen molecule diameter is little, escape velocity fast, compare placement oxygen and hydrogen about anelectrode-negative electrode and jointly participate in electricity flocculation mode, there is better air supporting/flocculating effect。Especially to calcium and magnesium cation in the water of negative electrode motion, liquidating with floating hydrogen stream, form more abundant flocculation sediment and get off, in water, TDS total amount declines simultaneously。
Water through above-mentioned preliminary purification without membrane electrolytic cell, in the middle part of insulating spacer pipe, tapping passes through the first water penetration barrier film → intermediate active charcoal filtering layer → the second water penetration barrier film, last from outlet output, the filtration physical treatment of water pollutant physically based deformation absorption filter element and first, second water penetration barrier film is purified removal further。
(3) at insulating spacer pipe Inner electrolysis voltage U, substantially linearly successively decreasing from anode (top) to negative electrode (bottom), voltage (current potential) value at circumferential openings place, middle part is about the 1/2 of total voltage。Namely same current potential it is in owing to metal cylinder and negative electrode are electrically connected by wire, therefore from the middle part of insulating spacer pipe, perforate water inlet the → the first water penetration barrier film → intermediate physical absorption filter element → the first water penetration barrier film → metal cylinder is to water outlet, and physical presence has a voltage drop=1/2U。
Due to the existence of current potential 1/2U in the middle part of insulating spacer pipe, actually at above-mentioned interval the second electrolyzer constituting a diaphragm electrolysis mode, metal cylinder is the second negative electrode, and in the middle part of plastic partition sleeve pipe, current potential 1/2U is equivalent to second plate。Water after processing without membrane electrolytic cell enters the second electrolyzer electrochemical reaction again from perforate in the middle part of insulating spacer pipe, and the physical absorption of the membrane filtration of electrochemical treatments and physical absorption filter element affix first, second water penetration barrier film processes slitless connection organic integration, it is achieved deeper Water warfare。
(4) in the present invention, the structure of first, second water penetration barrier film shows as the aquaporin region excessively of countless permeable micropore on microcosmic, owing to first, second water penetration barrier film is that non-conductive material is made, thus produce voltage drop in aquaporin in crossing of permeable micropore, namely, after putting on external electrode (anelectrode) and interior electrode (negative electrode) when the decomposition voltage of electrolysis power, in the permeable micropore of first, second water penetration barrier film, voltage landing relation is formed。
And liberation of hydrogen during water electrolysis, the gas that oxygen evolution reaction generates easily enters crossing in aquaporin and generating bubble in the water crossed in aquaporin of permeable micropore, first, in the narrow and small environment crossed in aquaporin of the permeable micropore of the second water penetration barrier film, bubble is easy to broken thus producing localized hyperthermia's high pressure, and then inspire efficient water body plasma discharge with minimum voltage, first, in second water penetration barrier film and first, in second 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 significantly high reactivity, the chemical reaction being difficult under usual conditions or speed is difficult to can be made to become very rapid, plasma group is generated by water body electric discharge, can be greatly improved in water body the degradation efficiency of pollutant), the oxidisability of this hydroxyl radical free radical transient state oxidation factor is extremely strong (exceeding ozone), the existence time in water is extremely short again simultaneously, 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。
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 in the countless small permeable raw hole of first, second water penetration barrier film and carries out by the present invention, rely on the gas that water electrolysis liberation of hydrogen, oxygen evolution reaction are generated, enter and first, second water penetration barrier film brings out water body self gasification, and then inspire efficient water body plasma discharge with minimum voltage, water body plasma discharge can be inspired, water generates the hydroxyl free base class transient state oxidation factor of great sterilizing ability。The oxidisability of this hydroxyl radical free radical transient state oxidation factor is extremely strong, has extraordinary bactericidal effect, it is possible to join in water outlet, and the existence time in water is shorter again simultaneously, it is possible to direct-reduction is water thus not staying any toxic and side effects after sterilization。
Above-mentioned ultralow pressure plasma discharge process, carries out particularly fierce in the second water penetration barrier film, this is because the second water penetration barrier film is closest with the second negative electrode that metal cylinder is constituted, it is possible to absorb a large amount of high energy electrons of negative electrode release。
Due to ultralow pressure plasma discharge, from outlet to household drinking water pipe-line system, release has a considerable amount of plasma group。These cluster ions have extremely strong oxidation or reproducibility, and organic pollutants, antibacterial, microorganism are had extremely strong degraded or deactivation；Meanwhile, these cluster ions degradation period in water again quickly, is unlikely to long-time accumulation, especially seldom there is toxic and side effects。So that it is guaranteed that central water purifier is after removing in water and making chlorine, it can be ensured that the drinking water pipeline of household internal has still thoroughly stopped the possibility of generation microorganism, virus bacterium " polluting for three times "。
(5) the optimized Land use systems of the water outlet of apparatus of the present invention sewage outlet is that namely sewage outlet is connected with the water tank of toilet as flushing supply, by closestool flushing valve control；The water outlet of certain sewage outlet can be used for family and waters flowers or mop floor。The water purifier of the present invention is when normal operation, source pollutant in water can collect around at anelectrode, therefore sewage outlet is arranged on anelectrode place, each water outlet of such sewage outlet is all equivalent to the once automatic clean and maintenance to water purifier, simultaneously in insulating spacer pipe, the flocculate of precipitation can also be discharged from sewage outlet under the effect of tap water hydraulic, and not only using water wisely but also achieved the automatic clean and maintenance of apparatus of the present invention simultaneously。
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 essentially identical。
In the present invention, if the permeable aperture of first, second water penetration barrier film excessive (namely microporous space is excessive) is equivalent to and in a disguised form increases electrode diameter (electrode curvature radius) and cause the initial excitation voltage of discharge in water to increase, and make generation bubble volume become to reduce greatly the catalytic specific surface area of gas-liquid two-phase。And if the permeable aperture too small (namely microporous space is too small) of first, second water penetration barrier film, electrolysis aerogenesis can be made to occur or gas producing efficiency is extremely low, little can cause that in barrier film, in each micropore, the point discharge of numerous little radius of curvature electrode cannot be normally carried out to a certain extent。Therefore, through the repetition test of inventor, it is determined that the range of aperture size of the permeable micropore of described first water penetration barrier film and the second water penetration barrier film is 2 millimeters～1 nanometer, and aperture size differs each other each other less than 20%。
The shape uniformity of membrane micropore and the uniformity of pore size are very big on plasma discharge impact in film。For better more generation hydroxyl radical free radical plasma group, it is preferred that in use, each permeable micropore of described first, second water penetration barrier film is respectively formed plasma discharge。So when using electric discharge, direction of an electric field between anodic-cathodic can pass through the plasma group of each permeable micropore, all mistake in aquaporin that plasma discharge is directed to water penetration barrier film carries out, thus water body plasma discharge can be inspired with minimum voltage, water generates the transient state oxidation factor of a large amount of great sterilizing ability, can be greatly improved in water body the degradation efficiency of pollutant, better carry out sterilizing etc.。
For making electric discharge in film be prone to carry out, it is required that the water penetration barrier film of first, second water penetration barrier film preferred hydrophilic, hydrophilic film surface can form hydrogen bond ordered structure with water, it is possible to improves fenestra water-filling wet face state, is conducive to plasma discharge process in film to be performed continuously over。
Improving further of technique scheme is: in described insulating spacer pipe, the end cap place near top is provided with flocculation grid device, and described anelectrode is arranged between flocculation grid device and the end cap at top, the electrode that described positive electricity extremely aluminum or ferrum are made。Aluminum or ferrum anelectrode so can be utilized to dissolve the coherency of the hydroxide generating aluminum or ferrum under the function of current to the colloidal substance that condenses in water so that water obtains purifies, mainly comprise three processes: (1) " sacrificial anodes " electrolytic oxidation produces coagulant；(2) water-borne glue body particle destabilization；(3) de-steady colloid forms floccule body。Wherein, the interionic interaction produced due to " sacrificial anodes " oxidation makes micelle electric double layer be compressed, the counter ion that electrolysis simultaneously produces makes electrostatic repulsion reduce with the ion generation charge neutrality effect in water, and it is leading to make Van der Waals absorption affinity account for, promote colloid generation agglomeration effect, and ultimately forming thicker floccule body, mat action of gravity separates removal from water。The present invention uses the materials such as Organic substance that electric flocculation technique can remove in water simultaneously, antibacterial, turbidity, toxic heavy metal。Compared with chemical flocculation, owing to negative electrode can precipitate out hydrogen, there is flotation effect, be not necessary in water and add chemical agent, thus water does not have SO4 2-、Cl-A large amount of gatherings；Compared with biological treatment, because not needing cultivating microorganism, it is only necessary to electronics is implemented water and processed, thus treatment time of water is short, and timeliness is high。
Preferably, described metal cylinder is rustless steel or the titanium material coating cylinder made of platinum group oxide。
Preferably, described negative electrode is close to the bottom head covers of metal cylinder, and described negative electrode has through hole。
Preferably, described anelectrode is close to flocculation grid device, and described anelectrode interval has some through holes。
