Description

ELECTROLYTE-FREE STERILIZING WATER GENERATOR

The present invention relates to an ozonated water producing apparatus for producing ozonated water for electrolyzing raw material water by using an electrode to obtain ozone in an anode generating gas. The present invention minimizes the resistance by the electrolytic solution in the electrolysis reaction, And more particularly, to an ozonated water generating apparatus for increasing efficiency and maintaining a constant distance between electrodes.

Ozone has strong oxidizing power as an oxygen isotope, and its ozone is applied to various industrial fields such as water treatment, sterilization, deodorization, decolorization and environmental field.

Such ozone finally decomposes by self-decomposition and returns to harmless oxygen. Therefore, there is no problem of secondary contamination due to residual chemicals or reaction products compared with sterilization, deodorization and decolorization methods using conventional medicines.

Known methods of generating ozone include a discharge method, an ultraviolet lamp method, and an electrolysis method.

First, the silent discharge method is a method of generating ozone by exciting and reacting oxygen by discharge using oxygen gas or oxygen in the air. An apparatus for generating ozone by this silent discharge method is disclosed in Korean Patent No. 0479522.

In this silent discharge method, as the concentration of ozone generated by ozone generated by silent discharge increases, the decomposition reaction of ozone actively progresses, making it difficult to generate high concentration ozone. Further, there is a problem that nitrogen in the air is oxidized and nitrogen oxides can be introduced.

Second, the ultraviolet lamp method is a method of generating ozone by exciting oxygen by ultraviolet rays to generate ozone by photochemical reaction, and is disclosed in Korean Utility Model No. 0432696.

This ultraviolet lamp method generates low concentration ozone (less than 10 g / N), consumes a very large amount of power (550 KWH / kg.O3), and reduces the generation of ozone by 40% at a humidity of 50% .

Third, the electrolysis method is an efficient method by electrolyzing the raw water to obtain ozone in the anode generating gas, and there is no impurity, and unlike the silent discharge method, ozone is easily dissolved in the raw water, and ozone loss is small.

In the conventional electrolytic ozone generator, ozone was generated by using an electrode such as lead dioxide (PbO ₂ ).

However, since these electrodes are reduced to lead hydroxide (Pb (OH) ₂ ) or lead oxide (PbO) lead ion (Pb ²⁺ ) on the electrode surface, the structure of the electrode changes over a long period of operation, There is a problem that a phenomenon of deterioration occurs. In addition, lead dioxide has a toxicity problem due to lead.

A conventional electrolytic ozone generating apparatus is disclosed in Korean Patent No. 0564654.

Such a conventional electrolytic ozone generating device has a structure in which a high-priced ion exchange membrane is inserted between electrodes and the raw material water is arranged to move along the electrode surface. Therefore, resistance due to the electrolytic solution and a bubble layer formed on the electrode surface decrease the electrolytic efficiency A phenomenon has occurred.

In addition, the electrolytic voltage of the electrolytic cell must be set in consideration of loss due to electrode terminals, electrode plates, diaphragm, electrolytic solution, bubbles, hydrogen overvoltage, and oxygen overvoltage to the theoretical electrolytic voltage.

In addition, there is a problem that a scale is generated on the cathode during continuous electrolysis using raw water containing a hard substance such as tap water and ground water, thereby deteriorating the service life of the electrode.
