Description
Technical field
The invention relates to a kind of with ozone generating apparatus, and particularly relevant for a kind of with the ozoniferous electrolyzer of electrolytic process.
Background technology
In all dirts of water, comprise abiogenous etiologies such as enterobacteria, germ and former cysts, it is acute ill or even dead that the people who drinks polluted water is produced.Under comparing, other pernicious effect as the pollution of heavy metal is non-infectious often, and slowly outbreak.According to sanitation degree, the caused water-related disease of pathogenic organisms body such as intestinal bacteria, salmonella, vibrio cholerae, rotavirus and amoeba histolytica is easier to outburst and causes the popular state of an illness.The sterilization and disinfection technology that is usually used in eliminating or filter the biological pollutant in the water supply has 4 kinds, i.e. chlorineization, ozonize, hyperfiltration and ultraviolet ray.In water, effective 150 times of ozone, fast 3000 times of the speed ratio chlorine of its kill microorganisms cell than chlorine.The more important thing is that ozone left resistates after disassembling cytolemma is an oxygen.Ozone is to the destruction of microorganism, only passes genetic stew than ultraviolet ray and hinders it and grow up much effective again.In addition, hyperfiltration costs an arm and a leg on the one hand, can only stop that on the other hand microorganism but do not eliminate pathogeny.Therefore, in fact ozone has become the main sterilant of some city tap-water supplies in the world.
Ozone is the allotropic substance of oxygen, is the single molecule that three Sauerstoffatoms are formed.At occurring in nature, lightning can split into oxygen molecule single atom, and Sauerstoffatom is combined into the trilateral molecule of short lifetime again with oxygen molecule.Ozone also can continue to generate because of the ultraviolet radiation of the sun in the atmospheric layer outside.But, ozone also can be artificial, and it is that thousands of volts of voltages are applied on several aluminized Glass tubings, the air between pipe can be changed into pungent gas.Existing many reports that utilize preceding method (or be called " glow discharge ") on the document, United States Patent (USP) for example: the 5th, 503, No. 808, the 5th, 523, No. 310, the 5th, 824, No. 274, the 6th, 134, No. 806 just wherein several pieces of writing such as grade also have many ozone generation device commodity that utilize silent discharge simultaneously on the market.Producing ozone with glow discharge not only needs high-voltage, also need use dry air or pure oxygen.Because oxygen is to be decomposed at high voltage electric field, nitrogen also can be decomposed simultaneously, and produces NO
XAnd so on dangerous pollutant.The aqueous vapor of removing in the air inlet of discharge ozone producer is in order to prevent HNO
3With HNO
2Generation, these acid have corrodibility to producer.Reducing the used airborne aqueous vapor of ozone generation is not the part minor matter, but can reduce the dew point (dew point) of air.The reduction of dew point can significantly improve the generation of ozone, and for example dew point is when-40 ℃ are reduced to-50 ℃, and the generation efficient of ozone improves 15%.Yet humidity control is not the unique difficulty that generates ozone with glow discharge, and other problem still has ozone to leak (all harmful to operator and environment), the solubleness of ozone in water, and electrical safety all must think better of.Therefore, develop the ozone generation method of another high-level efficiency and less restriction, will help the universalness of ozone sterilization method.
Having come out with the synthetic ozone of electrolytic process, (a first piece of writing is reported as: Schonbein more than 160 years; Ann., Vol.50, P.616 (1840)), applying for a patent also of such technology surpasses 30 years (for example, United States Patent (USP): 3,256, No. 164, on June 14th, 1966).During electrolysis, be on the anode of electrolyzer, to apply low dc voltage and high current density, to produce ozone.Though electrolysis process consumes more energy (about 6: 1) than glow discharge, electrolytic process has higher current efficiency (electrolytic process can surpass 50%, and electric discharge is about 2%), therefore can remedy the loss of energy.Also have, produce ozone with electrolytic process and there is no such as humidity control, ozone leaks, NO
XByproduct is with ozone solution degree problems such as (ozone must water-solublely just produce the processing effect).The parameter that influences of the ozoniferous output of electrolytic process has: anode material, electrolytic solution, voltage, current density and solution temperature.Report as Foller and Tobias discloses: " The AnodicEvolution of Ozone "; J.Electrochem.Soc., Vol.129, No.3, March 1982; PP 506-515 (this report and in the present invention as a reference) is higher than 50% ozone current efficiency at 0 ℃ 7.3M HPF
6In the aqueous solution, apply 0.5A/cm
2Electric current is in β-PbO
2Anode and obtaining.Basically, it is similar to brine electrolysis that electrolysis produces ozone, and just the generation of ozone system uses as β-PbO
2Have high oxygen overpotential material as anode.But, oxygen can produce on anode still that (ozone current efficiency promptly is O
3Concentration and O
2The ratio of concentration), hydrogen then produces on negative electrode.Manyly promptly settle an ion-exchange membrane, produce in electrolyzer with oxygen and mix, as to be disclosed in the patent No. be 4 to prevent hydrogen at two interpolars with the ozoniferous research of electrolytic process, 416,747,4,935,110,5,114,549,5,927,196,5,997,702 and 6, in 143,163 the United States Patent (USP), these patents also all and in the present invention as a reference.At report of the Article of Foller and U.S. Patent number: in 4,316,782,4,541,989 and 5,154,895 (these three pieces of patents and as a reference), all use a fluorine-containing negatively charged ion as ionogen, with the output of raising ozone in the present invention.Yet fluo anion generally has corrodibility, may not be suitable for general purpose ozone generation device.Carry out with low dc voltage and big electric current because electrolytic process produces ozone, so DC electric power provides just and conforms to the characteristic of ultra-high capacity device, so the present invention uses the capable ozone generation of electric power module that comprises battery and ultra-high capacity device.In addition, the present invention is also with NaCl, KCl, NaNO
3Or KNO
3Etc. neutral salt replacement fluorine thing as ionogen, and normal temperature and without the film isolated electrode under carry out electrolysis.Salt is immanent commodity, though when water temperature was high, the current efficiency of ozone can be hanged down, normal temperature is kept easily more than low temperature.Therefore, can make one simple, par according to the present invention, and wieldy ozone generation device, can be used for the surface sterilization of the sterilization, fish, fruit etc. of the water at industry, family and SPA center, and available manufacturing collutory ozoniferous is to keep oneself clean.
Ozone is a kind of strong but oxygenant of environmental protection.It can kill morbific microorganism and decompose many organic compound, and these pollutents are difficult to remove in water usually.Ozone is after finishing disinfection, and it only produces O
2By product, another benefit that can obtain making water oxygen level to increase again.With ozonize water may be to make the most effective of nontoxic water and technology fast.Yet the carrying out of ozonize should be safety and economy.

2On anode, produce, describe as following half-reaction formula:
Cathodic reaction
(1)
Anodic reaction
(2)
The anodic reaction that is produced as a high potential of ozone shown in half-reaction formula (3)
For improving the current efficiency of ozone generation, i.e. O
3Concentration is to O
2The ratio of concentration, anode must use the material with high oxygen overvoltage.Platinum and glassiness carbon material promptly are the effective and stable candidate materials of ozone generation.Above-mentioned precious metal and the selling at exorbitant prices of glassiness carbon material can't be in order to make large-scale ozonizer.But, plumbous oxide, particularly β-PbO
2Be the more cheap desirable anode surrogate of more preceding two materials.Because Pb is in its highest state of oxidation, so PbO
2Under strong anodic polarization, can stablize.β-PbO
2Be to be deposited on the suitable substrates with oxidation style, for example platinum titanium mesh (representing) with Ti/Pt, be coated with the titanium net of iridium oxide, or be coated with the titanium net of tindioxide, and use the aqueous solution that contains lead nitrate, nitric acid and Sodium Fluoride to be electroplate liquid.That knows this technology knows β-PbO per capita
2Electrochemical deposition method, so locate to repeat no more.Based on stability (promptly resisting the ability of high oxidation state) and cost, the present invention selects Ti/Pt as the anodic base material, is negative electrode with the Ti/Pt that does not reprocess.Fig. 1 is the electrode arranged parallel of a preferred embodiment of the present invention, label 105 be meshed anode (Ti/Pt/ β-PbO
2), 107 is mesh cathode (Ti/Pt), it places the electrolyzer of label 101.Air enters in the electrolytic solution 103 via bubble generator 109, and this liquid can be made into being dissolved in as 10gNaCl in 1 liter of deionized water (deionized water, DI water), to suppress H in the half-reaction formula (1)
2Generation.Air has two tasks at this, and the one, take the ozone that in solution, produces out of, another is for providing the required raw material of cathodic reaction represented as half-reaction formula (4), and this reaction may surpass half-reaction (1), makes H
2Generation is suppressed.
Fig. 2 is another preferred embodiment, in electrolyzer 202, anode 204 and negative electrode 206 be concentric(al) circles and with anode placed in the middle between.Similarly, air flows to negative electrode 206 via bubble generator 208, carries out above-mentioned functions.Electrolytic solution 200 can be salt solution, or needs the water of ozonize.In other words, comprise electrolyzer 202, electrode 204 and 206, the electrolyzer that reaches bubble generator 208 can directly place water, as aquarium, to carry out ozonize when participating in the cintest, makes water keep clean state.Even water flows through electrode, enough ozone (for example, the city water processing establishment often uses 1-3ppm ozone) also can produce in electrolyzer, with sterilization drinking-water.So the electrolyzer carried of the present invention is installed on select location on the water pipe with electrode, can form successive and flow through the formula ozonation system, carries out online water treatment.As the electrolyzer that Fig. 1 and Fig. 2 drew, can be made into the spatial size of the utensil of packing into, in the handle as brush, be used for medical instrument and semi-conductive surface cleaning, and the surface sterilization of meat, fish and fruit.Ozone can be effectively and the processing of putting things right once and for all is provided in many dry types and wet type production application economically.
Traditionally, the ozone concn in the water is to measure with iodimetry.In this method, iodide ion I
-By ozone oxidation is iodine molecule I
2, iodine molecule forms the triiodide ion I of brown again with iodide ion
3 -, the reaction metering is as follows:
Electrolytic process is better than one of advantage of glow discharge in order to produce ozone, is that low dc voltage can be used for wet process as 3～18V.The voltage (often using thousands of volts) that this dc voltage is required far below the aura method, meaning is that the cost of electrolytic process is lower, and need not transformer, civil power, and the strick precaution of electrical hazard.Though at the O that produces equivalent
3, electrolytic process may need the electric current higher than glow discharge, and only the energy requirement of electrolytic process can satisfy with an exquisite design.That is exactly to supply required voltage and electric current economically and effectively with the ultra-high capacity device.The ultra-high capacity device can store the energy of battery no better than, and the ultra-high capacity device can discharge and recharge as traditional capacitor apace on the other hand.Therefore, the ultra-high capacity device is the desirable component in the ozoniferous DC power supply of electrolytic process." ultra-high capacity/battery " that Fig. 3 comprises I, II and three function squares of III blendes together the circuit layout of electric power.Square I is a power circuit, and wherein battery 301 is in parallel with ultra-high capacity device 303, and with diode 302 protection batteries 301; to prevent the reverse charge of ultra-high capacity device 303; this battery 301 for example is a drying battery, lead-acid cell, nickel-cadmium cell; nickel metal hydride battery; lithium ion battery, lithium macromolecule battery, fuel cell; metal-air battery, and solar cell.The energy that utilizes battery 301 to be provided, ultra-high capacity device 303 can produce O to load 314 or electrode 1 and 2 (wherein 1 is anodal, and 2 is negative pole) power supply then
3 Load 314 constitutes switching circuit square II with N passage FET 313.Along with FET313 does to switch rapidly with hundreds of hertz frequency, ultra-high capacity device 303 is promptly to load 314 supply pulse electric power.The operating frequency of FET313 and periodic system are by being controlled with the represented self-excited type multi-resonant oscillating circuit of square III.Vibrator is mainly by high speed C-MOS NOT lock, 305 and 306 compositions, these NOT locks are called phase inverter again, i.e. its output permanent with import opposite.For example, if input A is 0, then exporting B is 1, and output C is 0.When the B point is 1, a charging current is promptly arranged from B flow through resistor 307 and 311 chargings of 310 pairs of electrical condensers of diode.Similarly, same charging current resistor 304 to the A points of also can flowing through.In case electrical condenser 311 is charged to a setting voltage, the A point also becomes at 1 o'clock simultaneously, and B names a person for a particular job and immediately transfers 0 to, and the C point also will become 1.
In the moment that electrical condenser 311 stops to charge, electrical condenser promptly transfers discharge to, makes NOT lock 306 be output as rectangular wave, and the resistor 312 of flowing through switches FET 313.The same time that electrical condenser 311 begins to discharge, the A point becomes 0, makes the B point become 1 again, launches another time charge and discharge cycles of electrical condenser 311.In fact, NOT lock 305 and 306 functions with the capable flip-flop of self-excitation mode (flip-flop).The frequency of vibrator is mainly decided by the resistance of resistor 307 and the electrical capacity of electrical condenser 311.Yet resistor 304 and 308 also can influence oscillation frequency and cycle.Diode 309 and 310 constitutes a chopper.When variohm 308 is threaded to low order end, be maximum by B point to the charging current of electrical condenser 311, so electrical condenser 311 is with shortest time charging and discharge, and the output periodic width that this moment, C order is a minimum.Thus, " ON " time of FET 313 is minimum relatively, and load 314 is minimum from the electric power that the ultra-high capacity device obtained.On the other hand, when variohm 308 was threaded to high order end, the charging current of ordering from B was minimum, electrical condenser 311 discharges and recharges with the slowest speed, the output width maximum that this moment, C was ordered, so the ON time of FET 313 is maximum relatively, load 314 obtains maximum power.In sum, Fig. 3 is the power supply of a preferred embodiment, and the ozoniferous electric power size of its supply electrolysis can be selected 1% to 99% change by the impulse ratio of FET 313.Therefore, required ozone amount can produce with the electrolytic process of the impulse ratio that changes circuit.The embodiment of following example only is used for confirming effect of the present invention, and unrestricted its scope, it is a kind of simple that the present invention can provide, and electrolysis economic and that conveniently use produces ozonizer and prepares the fresh water of clarification.
