Description

[0001] OZONE GENERATOR USING UV-LED MODULE [0002]

The present invention relates to an ozone generator using a UV-LED module for generating ozone gas by irradiating ultraviolet rays of a certain wavelength with an oxygen-containing gas using a UV-LED module, and more particularly, And more particularly, to an ozone generating apparatus capable of generating ozone with a high stability and drastically reducing maintenance cost.

Ozone is an unstable gas that is highly active chemically, attacking bacteria and viruses in the air and water, various harmful gases causing fungus, odor, and harmful organic substances (solvant, pesticide, heavy metals, etc.) And oxidize it. Using these properties, air and water are clean and sterilized. On the other hand, ozone has a colorless, irritating odor, strong oxidizing power, and is composed of three oxygen atoms. Unlike chlorine, these ozone do not leave any harmful residues when used as an oxidizing agent, and they have strong sterilizing power to remove bacteria and viral bacteria, and have strong bleaching power. In addition, the machine is made and the smell of each kind of factory and garbage disposal plant is removed by ozone treatment and the working environment is improved.

The pesticide, harmful gas and heavy metal removal effect cleans up pesticide residues such as fruits and vegetables by washing with ozone water to purify and remove pesticides and heavy metal components from groundwater by ozone decomposition and purification, The organic gas is decomposed by ozone and discharged safely.

Such ozone mainly generates ozone by inducing physico-chemical changes by applying energy to air or oxygen. As a method of generating ozone, there are silent discharge method, electrolysis method, high frequency electric field method, and radiation method. The silent discharge method has been most widely used for energy efficiency, stability of performance, and convenience of operation and control.

As shown in FIG. 1, in the silent discharge method, a silent discharge occurs between + and - electricity by applying a high voltage to the discharge tube through a glass insulator, so oxygen in the air passing between the discharge tube glass and the body collides with electrical energy Ozone is generated in the process of breaking and recombining. At this time, heat is generated due to collision of electric energy in the body. Therefore, cooling water or air should be always flowed into the body.

However, when the industrial and large capacity are constituted, it is necessary to constitute a plurality of discharge tubes, and the configuration of the cooling equipment and the oxygen inflow equipment for each discharge tube becomes complicated, and the additional equipment becomes disadvantageous. Also, the lifetime of the discharge tube may be shortened or the efficiency of ozone generation may be lowered due to moisture or fine dust in the air or oxygen to be introduced.

In addition, the electrolysis method is advantageous in that there is no generation of nitrogen oxides, high concentration ozone can be obtained, and installation equipment can be small, but ozone generation amount is small and it is not suitable for industrial use or large capacity.

In addition, although the radiation irradiation method does not require power and has a feature of low ozone production cost, it is difficult to manage the radiation source, and it is difficult to produce high concentration ozone and difficulty in practical use due to difficulty in selecting the material of the reactor.
