Abstract
The utility model relates to an ozone generator device which generates ozone by electrochemical process, comprising anode and cathode assemblies, an electrolyte injection port for refrigeration system assembly, and an electrolytic tank. The ozone generator by electrolytic process adopts lead dioxide anodes of ABS plastic group, air reduced cathodes, phosphate electrolyte and a refrigeration system. The utility model which can generate ozone with high concentration has the advantages of energy saving, good safety, simple structure, small size, convenient operation, etc., suitable for salubrity disinfection, food preservation, live preservation of advanced fry, etc.
Description
The utility model is to belong to the ozonizer device that makes water oxidized generation ozone on anode by electrolysis process in electrolyzer.
Produce ozone and take corona discharge process usually, this method is that pure oxygen or air are carried out ionization and produce ozone through feeding discharge chamber after the pre-treatment.Equipment used is huge, the expense height, and inconvenience is moved, and the ozone concn that is produced is lower than 4%.When using air, also can produce deleterious nitride.Therefore, from late nineteen seventies, the device of electrolysis legal system ozone has appearred adopting.Electrolytic process is compared with corona discharge method, has characteristics such as simple in structure, easy to operate, generation ozone concn height.But also have some problems, for example: anode adopts the titanium base to be coated with the electrode that deposits plumbic oxide behind the platinum again among the Deutsches Reichs-Patent DE3432684A, and kind electrode costs an arm and a leg.Chinese patent CN87202205U adopts the electrode of iron-based deposition plumbic oxide to make anode, because iron-based and lead dioxide plating coat on phase boundary redox reaction can take place, generates nonconducting oxide compound (Fe during use
2O
3And PbO) middle layer causes when energising resistance to raise and generate heat, and causes coating to expand and damages.Deutsches Reichs-Patent DE3432684A
1Adopt the metal cathode for hydrogen evolution, its polarization of electrode is big, and groove is pressed height, power consumption greatly, but also needs barrier film or the device of collecting anodic gas is set, to making complex structure.Adopt the cooling system of cooling anodes outside surface in the U.S. Pat 4541984, electrolytic solution can not flow, so that cooling performance is poor.
In view of the foregoing, task of the present utility model is to provide a kind of barrier film simple in structure, no to produce the ozone concn height, and adopts the low special-purpose anode of a kind of cost with solution heating damage problem, and the electrochemistry ozonizer of less energy-consumption.
For this reason, the main points of technical solution of the present utility model are: one, select for use the plastic-based, lead dioxide deposited electrode of ABS to make anode assemblies.The lead dioxide plating coat of kind electrode and frosting can not produce the middle layer of nonconducting oxide compound.Two, cathode assembly adopts the air reduction process negative electrode.Three, electrolytic solution is to adopt the nearly neutral phosphate buffer soln of fluorion, pH value that adds a small amount of high absorbability.Four, the cooling system assembly of this device by cooling water intakeoutfall, cooling room, place cooling duct in the cooling room, and the cell liquor head tank of double as gas-liquid separator form.Like this, in the cooling anodes outside surface,, make electrolytic solution produce internal recycle automatically, thereby improve cooling performance also by the cooling duct in cell liquor head tank and the cooling room.
In addition, the technical solution of ozonizer of the present utility model will further be provided by drawings and Examples.
Owing to adopted above-mentioned technical solution, reached its intended purposes.Adopted ABS plastic base lead dioxide anode, acomia cause thermal damage can be used big current density, and size can cut out arbitrarily, and cost is low.Negative electrode adopts the air reduction process negative electrode, can not produce hydrogen, and bath voltage is low, energy-conservation, and no explosion hazard need not be provided with barrier film, favourable reduction means volume.Above-mentioned cooling system can make the automatic internal recycle of electrolytic solution, and cooling performance is obvious.
The ozonizer that the utility model is made is through adopting the concentration (O of its ozone of iodimetric analysis
3%) can reach 15～18%.When current density was 8～10 peace/square decimeters, the ozone productive rate reached 0.50～0.54 Grams Per Hour square decimeter.Therefore, the utility model can be applicable to sterilizations such as swimming-pool water, tableware, sterilisable chamber, tap water, also can be used for the fresh-keeping work in transit of fishery products fry, and fruit and vegetable is fresh-keeping etc.
