Description

Healthy bath water device for making
Technical field
The present invention relates to a kind of healthy bath water device for making, belong to the water quality advanced processing technology field of domestic 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, waterworks can't bear the heavy load helpless。
Along with the contaminated situation of tap water is on the rise, the mankind are about the problem also growing interest of own health, and the health problem of shower water increasingly attracts much attention, and develop and exploitation shower water filter has wide market prospect。
In daily life, the micro polluting substance in family's water supply enters human bodies typically via three kinds of channels: drinks, breathe and skin absorption。In shower process, the polluter that we absorb is much more more than in drinking water。During shower, hot water opens the pore on skin, remains chlorine residue and other polluters will be availed oneself of the opportunity to get in water。Polluter is absorbed by skin, then immediately proceeds to blood circulation, just as drinking water enters blood circulation round by digestive system, has same harm。Another noticeable place has sucked substantial amounts of steam when being have a bath, and causes human body to be easy to suck chlorine and other aquatic gases。
It is true that people is by breathing the chemical substance ratio many 6~80 times entered sucked from oral cavity。Radon in water, can evaporate after heating, enters human body by breathing, and long term accumulation can form pulmonary carcinoma。The volatile material contained in water is volatile organic matter (VOCs) mostly, and the important channel that two harm being can not be ignored is healthy is taken in skin absorption and breathing。On the other hand, shampoo, bath gel contain harmful or even carcinogenic chemical all in various degree, should reduce as far as possible or even avoid to use。
Existing market finding showering filter product, it is the pure physical cleaning mode adding special filter (such as calcium sulfite, KDF, solid layer of charcoal, high energy activation stone filter material etc.) with water pollutants such as Adsorption chlorine residue, there is the easily full deficiencies such as needing often replacing that lost efficacy such as limited capacity, filtrate。
Summary of the invention
The invention solves the problems that and technical problem is that: provide and a kind of can safely remove the pollutant such as chlorine residue and radon in water, the device for making of alkalescence or acid healthy bath water can be generated again according to actual needs。
In order to solve above-mentioned technical problem, the technical scheme that the present invention proposes is: a kind of healthy bath water device for making, including be provided with outlet close container, at least one pair of is as paired the first electrode of negative and positive and the second electrode and the electrolysis power for described paired anodic-cathodic is powered;The water penetration barrier film that non-conductive material is made it is provided with between described first electrode and the second electrode;The positive-negative polarity of described electrolysis power is changeable;Being provided with the active carbon filter core of complete coated described first electrode outside described first electrode, described water penetration barrier film is close to the outer surface of active carbon filter core so that described active carbon filter core separates with closing container, and described second electrode is positioned at closing container;Described closing container is connected for tap water with city by the first pipeline, and described active carbon filter core is connected for tap water with city by the second pipeline;When described first pipeline connection, the second pipeline disconnect and described electrolysis power Switching power polarity to make the second electrode be negative electrode, the first electrode be anelectrode time, produce alkalescence bath water;When the second pipeline connection, the first pipeline disconnect and described electrolysis power Switching power polarity to make the second electrode be anelectrode, the first electrode be negative electrode time, produce acid bath water。
When the present invention need produce alkalescence bath water time, the first pipeline connection, second pipeline disconnect, outer electrolysis power supply Switching power polarity make the second electrode be negative electrode, activated-carbon filter in-core cladding the first electrode be anelectrode。At this moment described closing container is with water penetration barrier film for boundary, and described negative electrode is in closing container, and described anelectrode is being closed outside container and is being coated with active carbon filter core at its outer surface。
In the present invention, the structure of water penetration barrier film shows as the aquaporin region excessively of countless permeable micropore on microcosmic, owing to 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, voltage landing relation is formed in aquaporin crossing of permeable micropore。Liberation of hydrogen during such 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, in the narrow and small environment crossed in aquaporin of the permeable micropore of 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, in water penetration barrier film and in the water of water penetration barrier film neighboring area, (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, there is extraordinary bactericidal effect, the existence time in water is shorter again simultaneously, can direct-reduction be water thus not staying any toxic and side effects after sterilization。
During controlling the water circulation, city enters bath water device of the present invention for tap water, and in the water of source, chlorine residue and radon shift to anelectrode, are tightly held by activated carbon through water penetration isolating membrane。Noxious pollutant (anion) in the water of source also with current traverse water penetration isolating membrane and active carbon filter core, is degraded by the direct oxidation of anelectrode surface。Also water penetration isolating membrane is occurred the transient state cluster ion that ultralow pressure plasma discharge generates (include e (solvated electron), OH, H simultaneously+, atom state hydrogen, OH-Deng) Strong oxdiative removes, thus obtain removing chlorine residue and radon etc. and in alkalescence, oxidation-reduction potential be bear, the alkaline purified water of the scrubbing that is suitable for deoiling。
When acid bath water produced by needs, when the second pipeline connection, the first pipeline disconnect, outer electrolysis power supply Switching power polarity make the second electrode be anelectrode, activated-carbon filter in-core cladding the first electrode be negative electrode。During controlling the water circulation, city, flows out through active carbon filter core and water penetration barrier film from space (namely outlet is arranged at this) between water penetration barrier film and closing container casing for tap water。Now, closing and constitute anode chamber between container casing and permeable isolating membrane, cathode chamber is then filled by the interior activated carbon burying negative electrode。Active carbon filter core has absorption, conduction and catalytic performance, is a kind of electrode material with applications well prospect, in the present invention, active carbon filter core with interior bury the first electrode together with, constitute three-dimensional combination electrode。When producing acid bath water, the activated carbon cathode surface of high-specific surface area and oxygen in water effect occur two electronic reduction reactions to generate H2O2, it is also added in anode chamber's water outlet。Reaction equation is:
O2+2H++2e→H2O2
Because the organic reaction of electrochemical degradation occurs at electrode surface, namely being aoxidized by the reactive intermediates reacting or being generated by electrode surface of direct electrode surface, therefore the conversion zone of electrochemical reaction concentrates on electrode surface and near zone thereof。And activated carbon has huge specific surface area, oxygen molecule can more efficiently reduce at cathode surface, thus adding generation H2O2Concentration。The Organic substance in former water can be adsorbed again due to activated carbon in electrolytic process, be concentrated to electrode surface, so source Organic substance in water is also degraded when entering active carbon filter core。
From microcosmic, coarse activated carbon granule is equivalent to the sparking electrode of numerous higher curvature radius, the water penetration barrier film that Xiang Yuqi is close to discharges a large amount of high energy electron, the hydrogen generated plus cell reaction or the participation of oxygen foam, film brings out plasma discharge, generate the transient state cluster ion (generating the principle of transient state cluster ion referring to the statement producing acid bath water) with good bactericidal action, joining in water outlet, final outflow water is eliminate the pollutant such as chlorine residue, radon and Organic substance, have the slant acidity bath water of good bactericidal effect。
The alkaline bath water that the present invention produces and acid bath water all eliminate the pollutant such as the chlorine residue in tap water and radon, and not needing the chemical detergents such as shampoo, bath gel and liquid detergent in use, it is to avoid when bathing, family supplies water and micro polluting substance in chemical detergent enters human body。
In order to improve plasma discharge characteristic in film further, it is possible to make described water penetration barrier film all adopt hydrophilic barrier film。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。
Preferably, the pore size of the permeable micropore of described water penetration barrier film and shape are essentially identical。
In the present invention, if the aperture of the permeable micropore of water penetration barrier film is excessive (namely microporous space is excessive), it 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 the aperture of the permeable micropore of water penetration barrier film too small (namely crossing aquaporin too small), electrolysis aerogenesis can be made to occur or gas producing efficiency is extremely low, the little permeable aperture that electrolysis aerogenesis can be made to a certain extent to cannot be introduced into micropore, so that plasma discharge cannot be normally carried out。Therefore, through the repetition test of inventor, it is determined that the pore diameter range of the permeable micropore of described water penetration barrier film is 2 millimeters~1 nanometer, and the aperture size of the permeable micropore of described water penetration barrier film 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 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.。
In order to better obtain the micropore of uniform pore diameter, and improve the hydrophilic of barrier film further, thus producing the more plasma group transient state oxidation factor of more great sterilizing ability (the more plasma group mean to generate in water), heretofore described water penetration barrier film preferably employs the barrier film that following method of modifying prepares:
