The present invention relates to a food waste treatment apparatus. In the related art, in order to remove odor generated in a food waste agitating chamber, an odor suction pipe is installed in a food waste agitating chamber, and an odor air is irradiated with an ultraviolet lamp (UV), and a photocatalyst and an activated carbon filter. Deodorized by passing through, or by heating the sucked odor with a heater and deodorized by passing through the catalyst and adsorption filter, or by sucking the odor with ionic wind and using plasma to decompose odor and remove secondary products. Odor was removed by heating or the like. These deodorization methods are bulky because ozone and odor are mixed and need sufficient time and space for decomposition. Ozone generators and UV lamps (UV) are adsorbed into the discharge tube and lamps depending on the time of use. The amount of radiation gradually decreased, and the catalyst and the filter also had the disadvantage of deteriorating function due to adsorption of foreign substances and oxides to the saturated state. Therefore, the initial deodorization was enough, but deodorization became insufficient as the use time of 2-3 months. In the food waste deodorizer, the pipe length is short and the odor and ozone reach incompletely decomposed state due to lack of contact time between ozone and odor, and the oxide and moisture, secondary products of the decomposition process, Adsorption accumulates on the surface and causes performance deterioration. Secondary products and moisture accumulate on the surface of the ultraviolet lamp, which causes weakening of the ultraviolet light.

The food waste of the present invention is a deodorizing device that maintains a deodorizing performance for a long time continuously with a complex smell mixed with various odors, and ozone generation maintains a constant concentration for a long time and the performance of the catalyst filter is also continuously maintained for a long time. It is configured to extend the deodorization performance of garbage significantly more than the existing food waste. Ozone (O ₃₎ of the production material is I'm using oxygen (O ₂₎ ozone by silent discharge to oxygen (O _2), plasma discharge, chemical degradation, irradiation with ultraviolet light (UV), etc. (O ₃₎ and the production of ozone If there are other elements such as nitrogen in addition to oxygen (O ₂ ) in the ozone generating part, they are bonded to each other to form an oxide material. Oxygen will not be produced if pure oxygen (100% purity) is used as the raw material in ozone production. However, if normal air is used as raw material air, nitrogen in the air is inevitably about 80%. Oxides, including the compounds, are adsorbed on the discharge electrode to hinder discharge and hinder the generation of ozone, reducing the amount of ozone generated over time. The discharge tube in which ozone is produced has a water inlet and an outlet that can be cleaned, and has a structure that can be blown and dried. The catalyst filter also reacts with ozone to produce OH groups, which promotes oxidation reactions, oxidizes odorous substances in contact with odorous substances, and their oxides are adsorbed and applied to the surface of the catalysts, thereby degrading the performance of the catalysts.

In the present invention, the ozone generator and the catalyst filter of the ozone generator adsorbed and coated with the oxide material are continuously maintained to maintain the concentration of ozone generation, and the state of removing the oxide material applied to the surface of the catalyst filter is maintained to maintain the performance of deodorization. It is. Oxides adsorbed on the ozone generating area and the oxides adsorbed on the catalyst filter are water-soluble combined with oxygen, so they can be washed well with water, so that water is sprayed at regular intervals to wash the ozone generating unit and the catalyst filter and ventilate with a fan. After drying, the ozone generator is operated, the agitator of the food waste treatment apparatus is operated, and the odor generated is passed through and deodorized. There are various kinds of catalyst materials, but supported catalysts such as cobalt, platinum, palladium, manganese, iron, etc., which can be washed with water, are used. The cobalt supported catalyst utilizes the function of a catalyst in water and dry conditions. Therefore, a fan is installed on the odor discharge port and water is sprayed from the flush jet device installed at the rear end to wash the accumulated oxide material of the ozone generating site and the catalyst filter, and the water is collected in the water tank or discharged through the drain pipe.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to disturb the gist of the present invention.

Power is applied to 1 (11). Electric valves are valves that open when the power is applied and do not apply the power. Power is applied to the ozone generating power supply device 16 and discharge occurs inside the ozone generating unit, and oxygen sucked in the stirring chamber 1 and nitrogen and odor are mixed inside the ozone generating unit 15 so that oxygen is generated by the discharge. Is transformed into ozone (O ₃ ) and oxidized by deodorizing and combined with nitrogen and odor to form oxidized secondary formation. Oxides are adsorbed and accumulated in the ozone generator 15 to prevent ozone from occurring. As time passes, the ozone, odor and oxides discharged from the ozone generator 17 are further activated by the ozone in the catalyst filter and the odor is oxidized and deodorized and discharged through the air outlet 19. Oxides are adsorbed and applied to the surface of the catalyst, thereby degrading the performance of the catalyst and reducing the performance of deodorization. When the oxide material is adsorbed to the ozone generating unit 17 and the catalyst filter 18 due to the use for a certain period of time, the cleaning is necessary.

In the present invention, in order to improve these disadvantages and to maintain the performance of the deodorizing device to maintain the performance of the food waste treatment equipment to maintain the performance by removing the oxides causing the deterioration of the performance by cleaning at regular intervals. The catalytic filter reacts with ozone to increase oxidation, resulting in increased decomposition of odorous substances. Also, the remaining ozone remaining after reacting with odorous substances destroys ozone (O3) in the catalyst filter and changes its molecular structure to safe oxygen (O2). The problem of elimination and ozone emission is solved at the same time, and also, extraneous dust, pathogenic microorganisms and viruses in the stirring chamber have the effect of sterilizing by ozone contact of ozone generating unit and catalyst filter. .
