Description
Technical field
The present invention relates to a kind of circulating desk type water dispensers, belong to drinking water terminal water treatment technical field.
Background technology
Currently, water environment is exacerbated, the safe and healthy Frequent Accidents of drinking water quality, seriously jeopardizes the existence of people.Water
The pollutant that pollution is mainly generated by mankind's activity causes, it includes industrial pollution source, agricultural pollution source and domestic pollution source
Three parts.Increasingly the water pollution aggravated forms significant threat to the living safety of the mankind, become human health, economy and
The major obstacles of social sustainable development.It is investigated according to authoritative institution of the world, every year the whole world caused by drinking unhygienic water at least
20000000 people are dead, and therefore, water pollution is referred to as " world's number one killer ".
Domestic and international most of waterworks are so far still using precipitation, filtering, the outmoded process of chlorination, by rivers
Water or underground water are simply processed into drinkable water.However, it spreads unchecked and pours in face of trade effluent, rural sewage and sanitary sewage wildness
Life water source, waterworks can't bear the heavy load helpless.Along with tap water from water factory through water transfer pipe network and high-rise water storage
Case reaches and pollution is added caused by drinking water terminal, and it is health that municipal tap water dare not have been said.Especially, tap water adds
Although chlorine can be killed effectively except germ, can also generate more halogenated hydrocarbon compound simultaneously, the contents of these chlorinated organics into
Increase again, be the significant source that the mankind is caused to suffer from various diseases.Even boiling tap water, above-mentioned residue still drive no
It goes, the carcinogenic substances such as nitrite and chloroform can also increased.That is, even if the safety coefficient of drinking water is also not high
's.
Existing purification of water quality product or drinking water related product, predominantly medium adsorb or will be in water using the filter membrane in various apertures
Nuisance intercepted the physics mode treatment process filtered out.Since activated carbon class sorbing material is easy to saturation failure, and
Various filter membranes are easy to be contaminated by bacterial again or organic matter obstruction or damaged, thus actual conditions be can not be such as Theoretical Design
It is desired to accomplish like that the sufficiently cleaned up of water pollutant.At the source water pollution of getting worse, existing physics mode
Science and engineering skill far can not ensure water quality reaching standard.But physics mode water treatment technology also has an advantage in that, will not exactly generate
Toxic byproduct.Therefore the water quality of traditional RO membrane reverse osmosis filter method production is the safest, but is exchanged for the generation that ensures safety
Valency is then up to the even more converse concentrated waters of 40%-70% and is wasted be discharged into sewer pipe, cause huge water resource and
Waste of energy, and the cost replaced after the blocking of RO films is very high.To reduce or even reach no effuent discharge, water resource is saved,
Various patented technologies are had been developed that so far.It is used or by the pollutant in concentrated water first through molecular sieve for example, converse concentrated water is stored it
Cleaning blowing time or direct through non-return valve is reduced Deng filtering Posterior circle reuse or adjustment waste water ratio or by electrical control
It returns and is diluted in tap water main line or with " the double water of double films " pattern, water quality based water utilization, etc..The common deficiency of these technologies, one
It is not consider from overall system design, simply local single measure, often makes system overall work unbalance；The second is do not consider
From starting with into water condition for membrane component is improved, mitigate the live load of membrane component, it may be said that it is " palliative ", so so far
The product that yet there are no real utility goods comes out.
In comparison, it is a kind of excellent height although Water Treatment technique has cheap many advantages, such as being simple and efficient
Grade oxidation technology, but electrochemical treatments should not handle occasion list in itself there are a series of problems in civilian terminal Drinking Water
It solely uses, so far there is not yet in daily life water treatment field and closes extensive use.To find out its cause, one is Water Treatment technique
The enough reaction time is needed, and in daily life water occasion, from start, to water outlet, only several seconds, pollutant exist water purifier
The residence time is too short in water purifier, has little time to complete related chemistry reaction treatment at all；The second is have can for Water Treatment technique
It can be with certain toxic side effect.For example, although chemical oxidation reaction technique can potent inactivation of bacterial, depth degradation organic matter,
Go water removal in various harmful substances, but all kinds of Strong oxdiative factors that chemical oxidization method is generated be substantially non-selectivity, can not
Control, if dealing with the novel substance not having in most probably generating source water improperly, jeopardize safe drinking water instead；Just because of this, in the people
Many daily life drink water purifyings handle occasion, can be described as the application of Water Treatment technique double cautious.
However, in the unprecedented serious pollution of water environment, conventional physical water purifier today unable to do what one wishes, examine closely again
The possibility that concern Water Treatment is applied in Drinking Water purified treatment, it is ensured that people's life drinking water quality safety has
Highly important realistic meaning.

Member.
The working mechanism of the present invention and the advantageous effect brought are presented below.
The water container of crossing is using first, second water penetration membrane as boundary：The first electrode pair sets up separately permeable first
Property membrane both sides, the negative electrode of the first electrode pair is being crossed in water container, and its positive electrode is being crossed outside water container；Described second
Electrode pair sets up separately in the second water penetration membrane both sides, and the positive electrode of the second electrode pair is being crossed in water container, and its negative electrode
It is crossing outside water container.Certainly, cavity is internally provided with as crossed water container, first or second water penetration membrane is arranged on cavity housing
On, then the negative electrode for the second electrode pair being arranged in cavity or the positive electrode of first electrode pair, which are considered as, was arranged on water container
Outside.
First by taking first electrode pair as an example, the positive electrode of first electrode pair is only with crossing in water container that penetrate through first permeable
Property membrane infiltration water contact（Positive electrode is not contacted directly with crossing the water of water container）, anode direct oxidation reaction was transferred to
It is carried out outside water container, reaction product of anode is drained outside container, will not return again to pollution water quality in container.Meanwhile the moon in water
Contact scar object is acted on such as chlorine residue, various harmful anions by anode voltage, can also be saturating through first in water out of container
It is outer with infiltration water discharge to move to water container for aqueous membrane.
The structure of the first water penetration membrane shows as the water passage region of countless permeable micropores on microcosmic in the present invention,
Since the first water penetration membrane is made of non-conductive material, thus voltage drop is generated in the water passage of permeable micropore, i.e.,
When the decomposition voltage of electrolysis power is applied to external electrode（Positive electrode）With interior electrode（Negative electrode）Afterwards, following voltage landing is formed
Relation：The outer positive electrode of first water penetration membrane（+）The voltage drop U1 of moisture film between → positive electrode and the first water penetration membrane → thoroughly
The water penetration membrane of the pressure drop U2 that aqueous membrane direct impedance generates → first and cross the anti-production of water resistance between the negative electrode in water container
Raw voltage drop U3.
And infiltration water of the positive electrode of first electrode pair only with the first water penetration membrane contacts, the positive electrode of first electrode pair
Close to the first water penetration membrane, liberation of hydrogen, the gas of oxygen evolution reaction generation during such water electrolysis easily enter permeable micropore
Bubble is generated in water passage and in the water in water passage, in the water passage of the permeable micropore of the first water penetration membrane
Narrow and small environment in bubble be easy to broken so as to generate localized hyperthermia's high pressure, and then efficient water body is inspired with minimum voltage
Plasma discharge generates hydroxyl free base class transient state in the first water penetration membrane and in the first water penetration membrane neighboring area water
The plasma of oxidation factor（Plasma is the 4th state of substance that same level is in solid-state, liquid, gaseous state, low temperature etc.
Gas ions are rich in electronics, ion, free radical and excited state molecule, and electronics has very high reactivity with ion, can make usually
Under the conditions of be difficult to or chemical reaction that speed is difficult becomes very rapid, discharged generation plasma group by water body, can be with
Greatly improve the degradation efficiency of pollutant in water body）, the oxidisability of the hydroxyl radical free radical transient state oxidation factor is extremely strong（More than smelly
Oxygen）, while existence time in water is again extremely short, therefore can be after generation rapidly to Organic substance in water（Such as bacterium）Deng pollution
Object is reduced directly to water after forming extremely strong degradation and itself rapid oxidation, does not stay any toxic side effect.
Second electrode pair is similar with first electrode pair, but the direction of voltage landing is opposite.Therefore likewise, the in the present invention
The negative electrode of two electrode pairs contacts the cell reaction for being to ensure that second electrode pair with the infiltration water of the second water penetration membrane
It is normally carried out, and great amount of hydroxy group radical type transient state oxidation factor can be generated.
Meanwhile under the action of second electrode pair, the metal cations such as calcium ions and magnesium ions, ferrimanganic excessively in the endogenous water of water container
It is precipitated Deng lasting, is discharged through the second water penetration membrane so that the hardness for crossing water in water container continues to decline, and weight is harmful in the water of source
Metal etc. progressively removes；And it is acted on based on the direct oxidation for crossing the anode of second electrode pair in water container, micro- life in the water of source
Object is inactivated, and organic matter is degraded.
In addition, the negative electrode of first electrode pair and the positive electrode of second electrode pair the 3rd group of electrode pair of equivalent composition（Yin, yang
Without membrane between electrode）, the microorganism in the water of source is made to be inactivated under its electric field action, can more preferably play the purification of electrochemistry
Effect.
In the use of the present invention, source water carries out electrochemical treatments through the electrolysis cells first, by calcium ions and magnesium ions in the water of source,
Ferrimanganic and the chlorate of strong oxidizing property, hypochlorite are discharged from water container excessively, and pass through the oxidation of hydroxyl free base class transient state
Factor pair source water is sterilized and organic matter degradation, then filters out in water and remains through the further physics interception of the membrane filter unit
Harmful substance（Toxic byproduct is only a small amount of H2O2And O3, H2O2And O3Half life of decomposition be usually no more than half an hour, not only not
Either absorbent module generates harmful effect and filter component or absorbent module can be killed filter assemblies of the meeting to rear end
Bacterium sterilizes）, so as to obtain the purified water of depth.The present invention uses the group of " preposition electrochemical treatments and membrane filtration postpositive disposal "
It closes, so as to overcome in background technology the combination of " the preposition processing of physical absorption-membrane filtration and electrolysis water unit postpositive disposal "
Various defects（Such as the easy broken invalid of filter membrane, the heavy metals exceeding standard etc. mentioned in the prior art）, obtain required pure
Water purification.
The present invention is equipped with booster pump, the booster pump and the second water inlet between first water outlet and the second water inlet

Two water inlets connect, and the second outlet of the triple valve is connected with the 3rd water inlet, and the 3rd water outlet is connected with the first water inlet.
In this way, the triple valve just has two states, it is the first state that the outlet of booster pump is made to be connected with the 3rd water inlet respectively
With the second state that the outlet of booster pump is made to be connected with the second water inlet, when triple valve is in the second state, it is possible to obtain
The drinking water of health；It when triple valve is in first state, can move up the current in water tank, constantly from water container excessively
In by the way that so as to fulfill cyclic electrolysis, the various zwitterions in water are during cell reaction, from crossing in water container through the
First, the second water penetration membrane moved to and was exhausted outside water container, the water quality in water tank is made constantly to be purified.
Membrane filter unit is pure physical treatment mode in the present invention, it is ensured that the height of effluent quality especially Biological indicators
Security, and basic handling is clean before membrane filter unit is entered for the pollutant in source water of the present invention, therefore membrane filtration
The live load of unit mitigates significantly, and correspondingly, the service life of membrane filter unit greatly prolongs, and reaches the effect taken stopgap measures and effected a permanent cure
Fruit（Service life is long and the purified water water quality that generates is good）.
Since first, second water penetration membrane obtains the clamping protection of paired electrode in the present invention, experiment proves, first,
Second water penetration membrane will not be scrapped in use because of premature failures such as damaged or obstructions, remain reliable and stable work
State；Even if it is also scum loosely occasionally to have fouling in first, second water penetration membrane and electrode surface, in electrolytic process
The appropriate decomposition voltage polarity for switching the paired electrode for being applied to first, second water penetration membrane both sides, it is possible to easily
Remove deposition fouling of the anions and canons precipitate in electrode and water penetration membrane surface.
The present invention according to actual needs can also periodically swing to the polarity of two electrode pairs, at this time voltage when implementing
Grade can not also be identical, so that first, second water penetration membrane alternating degradation of organic substances, discharge harmful heavy metal ions,
Or the chlorine residue of discharge residual, various harmful anions etc., the quality of purified water so can be not only further improved, is given full play to
The catharsis of electrochemistry, and first, second water penetration membrane can be protected, extend its service life.
In order to further improve plasma discharge characteristic in film, the first water penetration membrane and the second water penetration can be made
Membrane all uses hydrophilic membrane.Hydrophilic film surface can form hydrogen bond ordered structure with water, can improve the leaching of fenestra water-filling
Profit state, the plasma discharge process in film that is conducive to persistently carry out.
Preferably, the aperture size of the permeable micropore of the first water penetration membrane is essentially identical, second water penetration
The aperture size of the permeable micropore of membrane is also essentially identical.
In the present invention, if the permeable aperture of first, second water penetration membrane is excessive（I.e. microporous space is excessive）It is equivalent to
In a disguised form increase electrode diameter（Electrode curvature radius）Discharge in water starting excitation voltage is caused to increase, and makes generation air bladder
Product, which becomes larger, reduces the catalytic specific surface area of gas-liquid two-phase.And if the permeable aperture mistake of first, second water penetration membrane
It is small（I.e. microporous space is too small）, it can make that electrolysis aerogenesis can not occur or gas producing efficiency is extremely low, it is small to lead to a certain extent
Causing the point discharge of numerous small curvature radius electrode in each micropore in membrane can not be normally carried out.Therefore, by inventor's
Repetition test determines that the permeable pore diameter range of first, second water penetration membrane is less than being equal to 2 millimeters and more than or equal to 1 nanometer.
The shape uniformity of membrane micropore and the uniformity of pore size influence plasma discharge in film very big.In order to
More preferable more generation hydroxyl radical free radical plasma groups, it is preferred that when in use, the first water penetration membrane and second permeable
Plasma discharge is respectively formed in each permeable micropore of property membrane.So when using electric discharge, the direction of an electric field between anodic-cathodic
The plasma group of each permeable micropore can be penetrated, by plasma discharge be directed in all water passages of water penetration membrane into
Row so as to excite water-outlet body plasma discharge with minimum voltage, generates the transient state oxygen of a large amount of great sterilizing abilities in water
Change the factor, the degradation efficiency of pollutant in water body can be greatly improved, preferably carry out sterilizing etc..
Better hydrophily can be made it have by being modified to membrane, and the aperture size of micropore is uniform, tool
Well known physically or chemically technology, such as shaping of fenestra Regularization, optically catalytic TiO 2, pole can be used in modifies technique
Narrow high-voltage pulse is to film pretreatment, etc..Its meaning is not only in that the raising of efficiency, also effectively prevents because current density is excessive
