Description
Technical field
This utility model relates to a kind of central water purifier, specially one and is arranged on middle-size and small-size user (such as family, villa etc.) and registers one's residence the quality purifying device for water of total water inlet end, belongs to the water quality advanced processing technology field of Drinking Water.
Background technology
Currently, water environment is exacerbated, but domestic and international most of waterworks the most still uses the outmoded process of precipitation, filtration, chlorination, 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 the most commonly used disinfection of tap water technology, plays a key effect for microorganism in inactivation 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 prevent city from arriving Drinking Water for Residents terminal for tap water after in family's drinking water pipeline system it may happen that microorganism, virus bacterium " pollute " (note: " polluting for three times " is the proper noun that this utility model is created for sake of convenience) for three times.
Unfortunately, recent two decades carrys out people and gradually finds, 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 the most all absorbed by human body skin, long-term bathing chlorinated water, easily induction various skin disease or even cancer.Therefore, considering from health perspectives, after city arrives Drinking Water for Residents terminal for tap water, first should chlorine residue in water thoroughly be removed, its usual way is to install central water purifier at total water inlet end of registering one's residence.
Central water purifier in early days 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 the enhancing realized along with water supply quality severe exacerbation and common people's drinking water safety, more and more higher to the purification of water quality performance requirement of central water purifier, structure also becomes increasingly complex, cause equipment manufacturing cost and water producing cost 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, the microorganism that may grow in how preventing household drinking water pipe-line system, virus bacterium " pollute for three times ", there is not yet any solution so far, and 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 the most easily causes urinary system calculus.In addition on healthy impact, hardness of water is too high, can bring many adverse effects 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 increases fuel consumption, and easily makes compromised container, etc..
Existing central water purifier does not has water softening ability substantially, and in current family, the Main Means of the water hardness to be solved is to buy 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 need to be wasted time and energy expensive through customary salt (sodium chloride) backwash.
Utility model content
This utility model to solve technical problem is that: provides a kind of microorganism that can stop household drinking water pipe-line system and virus bacterium etc. " polluting for three times " and can improve the central water purifier reducing hardness of water.
In order to solve above-mentioned technical problem, the technical scheme that the utility model 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 is arranged on the insulated enclosure end cap at 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 enclosed with the first water penetration barrier film and the second water penetration barrier film the most successively, physical absorption filter element, the barrier film that described first water penetration barrier film and the second water penetration barrier film all use 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 of physical absorption filter element described in this utility model cotton, porous ceramic micro filter material, granular active carbon, sintering activity charcoal or NACF are made.
This utility model device work process and purification mechanism are described as follows:
In the case of sewage outlet is closed, city enters into this utility model device for tap water source water from water inlet, after following multiple purifying processes, supplies water to whole family pipe-line system from outlet.
(1) anelectrode and the negative electrode at insulating spacer inner axial tube two ends constitutes one without membrane electrolytic cell.City enters this utility model device 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 more preferable air supporting/flocculating effect.Especially calcium and magnesium cation in the water of negative electrode motion, liquidates with floating hydrogen stream, forms more abundant flocculation sediment and get off, and 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, finally exporting from outlet, water pollutant filtration physical treatment based on physical absorption filter element and first, second water penetration barrier film is purified removal further.
(3) at insulating spacer pipe Inner electrolysis voltage U, the most linearly successively decreasing to negative electrode (bottom) from anode (top), voltage (current potential) value at the circumferential openings of middle part is about the 1/2 of total voltage.Same current potential i.e. it is in owing to metal cylinder and negative electrode are electrically connected by wire, therefore perforate water inlet the → the first water penetration barrier film → intermediate physical absorption filter element → the first water penetration barrier film → metal cylinder to water outlet in the middle part of insulating spacer pipe, 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 perforate in the middle part of insulating spacer pipe after processing without membrane electrolytic cell enters the second electrolyzer electrochemical reaction again, 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 this utility model, 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 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), in the permeable micropore of first, second water penetration barrier film, form voltage landing relation.
nullAnd liberation of hydrogen during water 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，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 produces 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 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.
Traditional water body plasma discharge technology, imports gas for producing water body plasma discharge often through outside in water, and imposes and add high intensity pulses voltage or hot conditions.This utility model is carried out in plasma discharge is then directed to the countless small permeable raw hole of first, second water penetration barrier film, rely on the gas that water electrolysis liberation of hydrogen, oxygen evolution reaction are generated, enter and first, second water penetration barrier film induces 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, can join in water outlet, and the existence time in water is the shortest simultaneously, can be reduced directly to water thus the most not stay any toxic and side effects.
Above-mentioned ultralow pressure plasma discharge process, carries out particularly fierce in the second water penetration barrier film, this is because the second negative electrode that the second water penetration barrier film and metal cylinder are constituted is closest, can absorb a large amount of high energy electrons of negative electrode release.
Due to ultralow pressure plasma discharge, there is a considerable amount of plasma group from outlet to release in household drinking water pipe-line system.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 the most quickly, is unlikely to accumulate for a long time, the most seldom there is toxic and side effects.So that it is guaranteed that after central water purifier makees chlorine in removing water, it can be ensured that the possibility that the drinking water pipeline of household internal has the most thoroughly stopped generation microorganism, virus bacterium " pollutes for three times ".
(5) the optimized Land use systems of the water outlet of this utility model device sewage outlet is to be connected with the water tank of toilet as flushing supply, i.e. sewage outlet, by closestool flushing valve control；The water outlet of certain sewage outlet can be used for family and waters flowers or mop floor.Water purifier of the present utility model is when normally working, source pollutant in water can collect around at anelectrode, therefore sewage outlet is arranged at anelectrode, so each water outlet of sewage outlet is all equivalent to the once automatic clean and maintenance to water purifier, in insulating spacer pipe, the flocculate of precipitation can also be discharged from sewage outlet under the effect of tap water hydraulic simultaneously, and not only using water wisely simultaneously but also achieved clean and maintenance automatic to this utility model device.
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 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 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 the most each other less than 20%.
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, 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..
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, can improve fenestra water-filling wet face state, and beneficially in film, plasma discharge process is persistently carried out.
Improving further of technique scheme is: being provided with flocculation grid device at the end cap at top in described insulating spacer pipe, 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 being simultaneously electrolysed generation 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 is separated from the water removal.This utility model uses electric flocculation technique can remove the materials such as the Organic substance in water, antibacterial, turbidity, toxic heavy metal simultaneously.Compared with chemical flocculation, owing to negative electrode can separate out hydrogen, there is flotation effect, be not necessary in water add chemical agent, thus water does not have SO4 2-、Cl-A large amount of gatherings；Compared with biological treatment, because need not cultivating microorganism, it is only necessary to electronics is implemented water and processed, thus treatment time of water is short, and timeliness is high.
