Operation principle and feature：
The basic chemistry of water electrolysis is that equation (1) is shown：
H2O(l)→2H2(g)+O2(g) Eo=1.23V (1)
Applying under 1.23V normal voltages, water generates hydrogen on cathode by electrolysis, meanwhile, water is also electric on anode
Solution generates oxygen.Equally it is anodic product, the yield of ozone is then very little.On the base material (titanium) of anode, it is necessary to plate
One layer can promote the catalyst that voltage (be known as oxygen and overpotential occurs) occurs for oxygen, and the yield of ozone can just have practical water
It is flat.
For example, stannic oxide is plated in the anode formed in titanium sheet, it can make oxygen that overpotential occur and be promoted to 1.52V.Cause
This, before anode generates oxygen, ozone can be generated largely.However, stannic oxide is semi-conducting material, it must be adulterated specifically
Element keeps stannic oxide conductive, and promotes stannic oxide and produce ozoniferous efficiency.The sun of stannic oxide and doped chemical composition
Pole is that " efficiency is most in all " electrolysis water generation ozone " anode catalysts (characteristic that must have catalysis reaction and electrochemistry) system
Height, cost is minimum, most environmentally friendly one group.
With stannic oxide (SnO2) based on ozone anode, need antimony dopant and nickel, improve stannic oxide respectively and lead
Electric degree and ozone generation rate.The available precursor (or starting material) of tin-three element of antimony-nickel and preferably, as table one show：
One electrolysis water of table generates ozone (O3) in SnO2The component of anode
The stannic oxide of antimony dopant is known as ATO, stannic oxide can also doped indium (In) or fluorine (F) be used as conductive element, point
Also known as it is ITO or FTO.When ATO is as anode electrolysis water, hydroxyl radical free radical (OH) will produce；SnO2The identification of anode quality,
It cannot be only according to the O in water3The height of concentration, should also measure the oxidation-reduction potential of water, and unit is mV.The oxidation-reduction potential of water
Value is the index of aqueous solution " redox " ability, than O in water3Concentration more can be shown that the ability of " sterilizing decontamination ".
One of inventor of this case is once with stannous oxalate (SnC2O4) butter of tin is substituted, solve stannic oxide anode system
When making, butter of tin leads to the problem of hydrochloric acid " injury equipment and operator " (Chinese patent application publication No.
CN105002517A).Synthesis of oxalic acid stannous must be using oxalic acid as one of raw material (another raw material is stannous chloride), and pharmaceutical grade oxalic acid
The market price be 33 times of technical grade oxalic acid.Therefore technical grade oxalic acid must be purified with " recrystallization ", technique includes 80 DEG C water-soluble
Solve oxalic acid, and 80 DEG C of hot solutions of filtering.But, if technical grade oxalic acid contains the hot water soluble impurity of energy, filtering and crystallization
Effect is bad.Equally it is technical grade, citric acid is not only cheaper than oxalic acid, and the purity of technical grade citric acid and pharmaceutical grade lemon
Sour same level.Therefore, the utility model is using stannous citrate as SnO2Derived compound, the utility model also use lemon
Lemon acid be complexing agent, collocation ethylene glycol fuel generate colloidal sol-gel, lock (tin-antimony-nickel) three metal ions, reduce they
Volatility under high temperature, it is ensured that the metal ratio that the catalyst film of synthesis has formula designed.It is aforementioned to utilize citric acid and second
The low-temperature combustion synthesis of glycol is that MP Pechini are initiated for 1967 in the Christian era, and obtain U.S. Patent No. 3330697.
The metal oxide catalyst that the method is formed has many advantages, such as " low power consuming, nano crystals, composition is uniform, structure is closely knit ".
The Section 2 of " electrolysis water leads to the problem of ozone " technology is to be solved, is the incrustation of cathode, need frequent scale removal guarantor
It supports (maintenance period is depending on the water quality of water inlet).The design of current " electrolysis water generation ozone " reactive tank, including stainless steel
(SS) source as the waste water of the base material of cathode and tap water or low stain as ozone.As electrolysis carries out a period of time,
Calcium and magnesium ion in water can with carbonate and water pollutant by the product of cathodic reduction, will all be deposited on the surfaces SS and by its
It is completely covered, becomes the incrustation for making SS insulate.Once SS cathodes are non-conductive, electrolytic cell just stops generating ozone, and anode Chang Lian
Band is impaired.At this point, electrolytic cell just must stop work, regenerated.To exempt the maintenance of cathode and the long-play of electrolytic cell, this
Utility model proposes following two kinds of solutions：
1) the chromium film of the surfaces SS coat foods grade
The technique that " high temperature oxidation and corrosion " is resisted with the coating chromium film of motor vehicle exhaust emission metal tube, by conductive food-grade
The plating of (trivalent chromium) golden yellow chromium film on stainless steel, will be as exempting from the cathode of maintenance.Chromium film is smooth compared with stainless steel densification, makes in water
Suspended matter be not easy to adhere to, meanwhile, the resistance to corrosion of chromium is strong, and have catalytic action.
2) carbon-coating of the surfaces SS applying conductive
With the material that carbon black is mixed with sticker, it is coated with manufactured cathode on metal base, in DC electric field, energy
By the O in water2It is reduced to H2O2, and then and O3Reaction generates hydroxyl radical free radical (OH), is peroxone reactions, such as China
Disclosed in patent CN105439258A.But, the needed O of the patent2With O3All from external input, and carbon black can be catalyzed carbonic acid
Calcium/magnesium carbonate crystallizes on cathode, and painting carbon cathode is made more rapidly to be completely covered than what is do not applied instead.The utility model is with ceramics
Adhesive, under 700-800 DEG C and anaerobic state, such as by carbon materials：Activated carbon, graphite, carbon nanotubes, graphene or " carbon materials-
Metal oxide " composite wood fixes the cathode for becoming exempt from maintenance on stainless steel.It is that elasticity is very high to apply carbon cathode technique
Technology, must asking for market can be more coordinated than chrome-plated process, such as：Change the color of cathode, promote the function of cathode (as generation is double
Oxygen water decomposes obstinate pollutant) and promotion electrolytic efficiency.It is preferred to apply carbon material, it is that " carbon materials-metal oxide " are compound
Material.
The electrolytic water device that the utility model is carried can generate two kinds of oxidants when energization operates：O3With O2, and one kind is also
Former agent：H2.The utility model is not by gaseous product (the i.e. H of three kinds of high activities2-O2-O3) separation, and allow they in a cell
The reaction of many " generating free radical " occurs for mixing.Wherein, O3It will be decomposed by the OH-ion in water, generate equation (2) extremely
(8) chain reaction：
O3+OH-→O2+HO2 - (2)
O3+HO2 -→HO2·+O3·- (3)
HO2·→H++O2·- (4)
O2·-+O3→O2+O3·- (5)
O3·-+H+→HO3· (6)
HO3·→HO·+O2 (7)
HO·+O3→HO2·+O2 (8)
In addition, the product O of anode3With the product H of cathode2, the chain reaction of equation (9) can also occur：
H2+2O3→H2O2+2O2 (9)
The product of equation (2) to (9), belongs to oxygen containing oxidant, abbreviation active oxygen.Active oxygen has strong
" sterilization " ability and high redox potential ORP value.Equation (2) to (9) is also shown：What anode generated is dissolved in water
O3, can be consumed by oxidizable species in water.Therefore, the quality of " electrolysis water generation ozone " technology electrode production, except measurement water
In O3Concentration should also measure the ORP value of Ozone Water.
The Section 3 of " electrolysis water leads to the problem of ozone " technology is to be solved to be：The potential burning of hydrogen and explosion crisis.This
The H of the electrolysis unit of utility model2Yield, in H2-O2-O380% or more, O is accounted in gaseous product2With O3About respectively account for 13% with
5%, remaining gas is water vapour and air.By H caused by electrolytic cell2It is completely converted into active oxygen, H can be eliminated2Safety
It threatens.
In order to promote H2Conversion ratio, the utility model develops online catalyst tower.Utilize the filtering with three-dimensional structure
Carrier, such as：Steel wire lump (SB), structured packing or filter plate of porous ceramic block.It is preferred that steel wire lump will via Pechini methods
