The present invention relates to an oil and fat decomposition apparatus using ozone, and more particularly, to an apparatus for decomposing fats and oils contained in sewage and wastewater discharged from restaurants, group meal facilities, schools, and food-related businesses using ozone.

As the diet is westernized, the consumption of meat, fast food and instant food is increasing, and thus the amount of fats and oils contained in sewage and wastewater discharged through sewer pipes is also increasing.

Thus, sewage and waste water with high oil content are attached to the inner wall of sewage pipe to block sewage pipes and prevent transportation of sewage, and to form an oil film on the surface of sewage flowing into sewage treatment plant to prevent oxygen supply and to sewage treatment facilities. Sticking together causes problems such as deterioration of sewage treatment efficiency.

In order to remove waste oil contained in sewage and waste water, a method of collecting waste oil collected on the upper part of the net grapple lab attached to the strainer and grate lab, or by using a chemical, microorganism or enzyme put into the grist lab To decompose the waste oil.

However, the method using the strainer and the net is very cumbersome and troublesome because of frequent cleaning or replacement of the strainer and the strainer, and the work is not easy due to bad smell. In particular, when entrusting such waste maintenance processing to a professional contractor is expensive. In addition, the method using the drug, microorganisms or enzymes may be lost when a large amount of sewage and waste water at the same time, it is complicated to supplement the drug, microorganisms or enzymes to increase the decomposition of waste oil. Most of all, the cost of drugs or microbial products is very high.

Accordingly, the present invention is to solve the above-mentioned problems by using ozone to provide a fat and oil decomposition device that is easy to process waste oil, excellent in the oil and fat decomposition efficiency, and does not require a large cost in waste oil and fat process. There is a purpose.

It is formed and installed. At this time, the outlet 148 is provided in the center of the rear panel 114, the outlet 148 is a means for discharging the air containing ozone to the outside will be described in detail later.

On the inner bottom surface of the case 110, an air unit 150 is installed to purify the air from the outside and pump it at a high pressure. The air unit 150 includes an air filter 152 for introducing and purifying air as described above, and an air pump 154 for pumping the air purified by the air filter 152 at high pressure. At this time, the inlet (not shown) of the air filter is installed to be in close contact with the inner bottom surface of the case 110, the air inlet is formed on the bottom surface of the portion where the inlet is installed, although not shown.

The partition wall provided in the inner space 116 of the case 110 is provided with an ozone generator 160 for generating ozone in the air conveyed from the air unit 150. The ozone generator 160 is formed in a cylindrical shape having a predetermined length, and an inlet hole 162 through which the compressed air is introduced is formed on a lower surface thereof, and an outlet hole 164 through which ozone-containing air is discharged. ) Is formed. In addition, the inside of the ozone generator 160 is provided with an ultraviolet lamp (not shown) for generating ozone by irradiating ultraviolet light to the air introduced through the inlet hole 162.

For reference, ozone (O ₃ ) is an allotrope of oxygen (O ₂ ) that exists as an off-white gas with a characteristic odor under normal pressure and room temperature. It is 1.5 times more dense and 12.5 than oxygen. It has a solubility of pear, and this ozone has strong sterilization, disinfection, decolorization and deodorizing effect that oxidizes hardly degradable substance and converts it into biodegradable substance. As it is 7 to 8 times higher than chlorine, its use is gradually increasing in the fields of sewage and wastewater treatment due to environmental pollution, and water treatment and sterilization of water resources.

In addition, various methods are used to generate ozone, including a method of generating ozone by generating a silent discharge, which is a dielectric barrier discharge (Dielectric Barrier Discharge), and generating ozone by electrolyzing water. And ozone is produced by irradiating a raw material gas containing oxygen with ultraviolet rays.

Among them, the method using ultraviolet rays is a photochemical method of generating ozone by irradiating ultraviolet rays to a raw material gas containing oxygen. More specifically, a general gas is usually used as a raw material gas containing oxygen. The ozone generator 160 of the present invention belongs to a method of dissociating and activating oxygen molecules by irradiating ultraviolet rays generated from a lamp and generating ozone by combining the activated oxygen.

On the other hand, the ozone-containing air generated in the ozone generator 160 is discharged to the outside through the outlet 148 provided on the rear panel of the case via the pipe 168. At this time, on the pipe 168 between the ozone generator 160 and the outlet 140, the check valve 172 and the pressure in the pipe to prevent waste water backflow or foreign matter flows through the outlet 148 A pressure sensor 174 is provided for measuring.

The fat and oil decomposition device 100 using ozone according to the present invention configured as described above is easy to install and repair due to its small volume and simple structure compared to the conventional fat and oil decomposition device. In addition, as described above, since only ozone is used to produce ozone, the amount of electricity used is low, resulting in high energy efficiency. In particular, the appearance of each component is made of SUS304 or its alloy, there is no fear of corrosion and excellent durability.

Looking at the fat decomposition process of the fat and oil decomposition device 100 using ozone according to the present invention as follows. At this time, the maintenance decomposition apparatus 100 is connected to the transfer hose 180, the other end of the transfer hose 180 provided with the air dispersing means 184 is assumed that the waste water stored in the sump.

First, when the power switch 122 provided on the front panel 112 of the case 110 is turned on, the ozone generation amount is adjusted using a pair of control switches 124, and then the operation switch 126 is operated. The oil decomposition apparatus 100 is operated.

When the fat and oil decomposition device 100 is operated, the air filter 152 flows in air from the outside and purifies the air pump 154, and the air pump 154 flows in at high pressure by introducing the purified air from the air filter 152. . In addition, the ozone generator 160 irradiates the air pumped from the air pump 154 with ultraviolet rays to produce ozone, and then sends the ozone to the outlet 148 through the pipe 168. At this time, the maintenance decomposition device 100 is provided with a control unit 190, the air pump according to the ozone generation amount measured by the ozone generator 160 and the pressure sensor 174 and the pressure in the pipe 168. 154, the operation of the ozone generator 160 and the check valve 172 is controlled.

The ozone-containing air generated through the above-described process is ejected into the sump of the collection well along the transfer hose 180 connected to the outlet 148. At this time, the transfer hose 180 is provided with an air dispersing means 184 to evenly eject the air containing ozone. In addition, the air dispersing means 184 decomposes the ejected air (air containing ozone) into fine bubbles to increase the contact efficiency with the waste water. As such, the contact efficiency with the waste water increases and the aerobic bacteria are activated and multiplied, thereby decomposing the oil contained in the waste water.

As described above, although the configuration and fat decomposition process of the fat or oil decomposition apparatus using ozone according to the preferred embodiment of the present invention are illustrated according to the above description and drawings, these are merely described as examples and the technical spirit of the present invention is described. Those skilled in the art will appreciate that various changes and modifications can be made without departing.
