Description

Ultrasonic Ozone Sterilizer {ULTRASONIC OZONE STERIZER}

Various methods of dissolving ozone in water or mixing in air to treat various kinds of water purification, purification, disinfection, odor removal, discoloration and oxidation using ozone characteristics have been developed. The method has not been developed so far.

The inventors of the present invention have developed an integrated ultrasonic ozone sterilizer that can easily make ozone at the necessary site and easily dissolve ozone and make dissolved ozone water into water vapor using ultrasonic waves to provide the required process. The sterilizer is thought to contribute greatly to the field of environmental industry, and thus the purpose of the invention was achieved.

Ozone is the strongest oxidizing element after fluorine among the elements invented so far.

Moreover, the ozone properties known to date are strong in oxidative properties and have strong active properties and react with various compounds in various forms.

In particular, ozone's effect on the living body destroys the cell membrane of the biological material, and general bacteria are sterilized in 30 seconds at 0.02ppm.

Another characteristic of ozone is that it smells even at very low concentrations and is non-residual due to self-decomposition within 30 minutes. The recovery of residual ozone can be easily removed with activated carbon in dissolved ozone water and 300 ° C in air. Is that there is.

By using these characteristics, ozone has been used instead of chlorine for the treatment of high-purity water in Europe, and recently, it is widely used for the purification of various sewage and wastewater.

However, until now, the method of using ozone easily in general households has not been developed. Looking at the cause.

first. This is because domestic ozone generators have not been able to develop compact type breakthroughs. For this reason, ozone generators have been developed only for industrial use, and it may be regarded as an early stage of development in the field of living environment or home.

Artificial methods for making such ozone gas have been used as a silent discharge method so far, and the conventional technology and problems with respect to the silent discharge method is shown in Table 1.

The measures taken to solve these technical problems are shown in Table 2. Same as

Summarizing the components of the measures taken in Table 2.

1. Ozone generator is a conventional ① cooling system. ② Oxygen supply system. ③ Generator system. ④ It consists of an electric control system, but the cooling system is air-cooled, the oxygen supply system is air, and the ozone generator is developed from argon welding monopole to ceramic multipole type, and ①, ②, ③ are integrated into a compact and compact type. .

2. The ozone melting contactor is a conventional ① air compressor system. ② Industry Organization System. ③ The ozone reactor system was replaced with one ultra-miniature gun generator and changed from the existing 3mm bubble to 0.1-0.2mm ultra-mini gun.

3. No ozone vapor generator has been developed so far, but the high-purity ozone gas made by ozone generator and ozone dissolving contactor can easily vaporize the ozone water by ultrasonic vibration and send the vaporized ozone to the necessary site by simple circuit configuration. It was developed to be compact.

Examine the behavior of the components.

1. The ozone generator part

In Fig. 2, the ozone generator is largely composed of a body and an electrode part.

The body was assembled without welding with ceramic finish plates on both sides to form a gas circuit, and was replaced by air cooling by attaching aluminum heat sinks on the front and back to increase cooling efficiency.

Most of the cooling effect is achieved in the cooling circuit shown in FIG.

The electrode part was completely developed from the existing monopolar electrode rods and developed as a multipolar stainless steel tube. The conventional method of the conventional + electrode tube made of stainless steel rods was not able to form a gas circuit. The efficiency was high and the concentration of ozone could be increased.

As an insulator between electrodes, it can be used semi-permanently as a special heat-treated hard glass tube.

2.Ozone dissolving contact part

It consists of a body and three inlet and outlet valves as shown in Figure 3 and is pumped.

The inlet pipe provides water pressure in the pump and flows in the inclined direction when the liquid hits the inclined part in the center, and because the bottom cross section is small, the flow velocity is fast and the end of the inclined part is vertical using the lift principle of the plane. The pressure is-, and ozone gas flows into this part.

The ozone gas introduced in this way passes through the area where the cross-sectional area becomes larger and is changed into the ultra-miniature gun, which is easily contacted with water and dissolved.

The central valve is an inlet valve for ozone gas and a backflow prevention device to prevent equipment damage.

The diameter of the micro bubbles generated in the existing diffuser device is more than 3mm, but the diameter of the bubbles generated is 0.1-0.2mm or less, and the volume of the bubbles is more than 1000 times different.

In other words, the smaller the bubble size, the larger the area in contact with water, so that it can be easily dissolved.

The circuit structure is eliminated in the process of the existing compressor → piping → ozone generator → piping → acid engine → bubble generator. As soon as the ozone gas passes through the ultra-melting contactor, it is changed to the ultra-fine foam.

Here, the ultra-mini-foamed bubbles are attached to distinguish them because most of them are described as microbubbles in the related literature, although the size of bubbles generated by existing industrial organs is 3mm or more.

3. Ozone steam generation part

The high concentration ozone water is introduced into the diaphragm of the ultrasonic generator from the storage tank and steam is generated by the ultrasonic vibration.

There are many ways to make steam, but ultrasonic method is economical and easy to use, and ozone is easily dissipated by heat, but ultrasonic can be used to generate steam even at room temperature.

The high concentration of ozone-dissolved steam is installed near the site of use and transported to maximize efficiency.

In addition, the method of recovering the residual ozone is easily recovered when the steam is passed through the activated carbon treated filter.

The effects of the ultrasonic ozone sterilizer can be classified into the improvement of each process of industrial activities and the improvement of living environment.

First, the part that can be used for each process of industrial activity should be the one to be disinfected.

In addition, it may be appropriate to disinfect in a range that is not suitable for disinfection with gas or does not change the composition of a given space. In other words, it means disinfection with steam, which is not suitable for disinfection with liquid or gas, and sterilization or sterilization at room temperature, which cannot be performed by heat treatment, may be optimal.

From the living environment side.

First, in the current humidifier function, we developed a humidifier that heats it to prevent germs from propagating. However, the ozone generator will be a humidifier in which bacteria are sterilized even at room temperature. The purpose of the existing humidifier is to control the humidity of the air. As it is used only in winter when the humidity is low, the present invention has sterilization and air purifying ability as well as humidity. In the summer, mold and bacteria can be dramatically sterilized and odor can be removed, so all seasons can be used. .

In addition, most of the food left at home is kept in the refrigerator, but the refrigerator's fridge does not kill food germs at low temperatures, but rather inhibits activity. Food storage is sterilized at room temperature and can be stored for a long time, so it will be an innovative method of storage.

In particular, where vegetables and unpacked foods are stored and managed, humidification and sterilization can be performed at room temperature at the same time, so the preservation period will be longer and freshness will be maintained, and considering the importance of the preservation period in the handling and processing of sashimi or meat. The developed ultrasonic ozone sterilizer will provide the optimal effect.

In addition, there are innumerable parts of general life that require both humidity and sterilization, but if the product is developed for the purpose, the present invention will double its value.
