In addition, the apparatus also includes: an aerating nozzle (12); an output line (30); and a check valve (40).

Description

[0001] Apparatus for generating chlorine dioxide gas [0002]

The present invention relates to a method for producing a chlorine dioxide gas in which a chlorine dioxide gas having a predetermined concentration is generated by aeration of air in a chlorine dioxide water, And it is possible to prevent the explosion by stopping the operation of the air compressor when the pressure of the air compressor is higher than a predetermined pressure and to reduce the size of the generator and to use both DC (battery) and commercial AC power, .

Chlorine dioxide, which is widely used as a chlorine substitute, is a substance that rapidly sterilizes most viruses including swine flu, bird flu and foot-and-mouth disease virus and has been used for disinfection of drinking water for a long time. And it is not influenced by pH. Chlorine dioxide reacts with amino acids such as cysteine, tryosine, and tryohan to denature proteins, react with free fatty acids to form lipid oxides, affect cell membrane changes and protein synthesis due to mRNA insufficiency, killing microorganisms .

This feature is widely used in the field of liquid chlorine dioxide and gas is a method to use liquid, but the technology has been developed for commercial use, but if you want to use chlorine dioxide gas, large-capacity equipment installed In fact, even if you want to use chlorine dioxide in the field, you can not use chlorine dioxide, which has many advantages because of the operational burden.

Especially, in the livestock sector, as the living standards have been improved and the consumption of meat has increased, the livestock breeding which was small in individual farms has become large scale. As the livestock breeding becomes large scale, It is true.

In addition, since chlorine dioxide gas is also used for disinfecting food materials stored in warehouses and the like, the chlorine dioxide gas generator that has been supplied so far has been enlarged, and the chlorine gas generator for use in the field has been developed This is more urgent than anything else.

The apparatus for generating chlorine dioxide gas according to the embodiment shown in FIG. 1 is for generating chlorine dioxide gas by mixing chlorine dioxide water with air, in which a predetermined concentration of chlorine dioxide water is stored, A solution storage tank (10) having an aeration nozzle (12) for aeration; An air compressor (20) for supplying air to the aeration nozzle (12) of the solution storage tank (10); A discharge pipe (30) for discharging the chlorine dioxide gas generated in the solution storage tank (10) to the outside; A check valve (40) installed between the solution storage tank (10) and the air compressor (20); A contact type micro-pressure gauge (50) for sensing the pressure inside the solution storage tank (10) and stopping the operation of the air compressor (20) when the sensed pressure is lower than or equal to a set value; .

In the solution storage tank 10, a lower region where chlorine dioxide water is stored and an upper region where chlorine dioxide gas stays are integrally formed, and an injection port 14 for injecting chlorine dioxide water is provided at an upper side of the solution storage tank 10, It is made of a material capable of withstanding contact with chlorine dioxide water and chlorine dioxide gas. For example, it may be manufactured in the form of a pressure vessel using PE or PVC resin.

A float-type water level gauge or a tubular water level gauge may be added to the solution storage tank 10 so that the water level of the chlorine dioxide water stored therein may be easily checked from the outside, or a part of the reaction tank may be formed of a transparent or translucent material, It is possible to make the water level of the water tank easily recognizable.

A contact type micro-pressure gauge 50 is provided in an upper region of the solution storage tank 10, that is, in a region where the chlorine dioxide gas stays, to indicate a pressure state inside the solution storage tank 10, The control unit 50 stops the operation of the air compressor 20 in addition to the pressure display function if the pressure is equal to or higher than the set value, which will be described later.

The concentration of the chlorine dioxide used as the raw material in the present invention is not adversely affected by the concentration, but the concentration of the chlorine dioxide water used in the present embodiment is 10 to 3,000 ppm.

In the present embodiment, the aeration nozzle 12 is for causing the air supplied from the air compressor 20 to aeration (acidify) in the chlorine dioxide water, and aeration is performed in the chlorine dioxide water to remove dissolved chlorine dioxide gas The concentration of the chlorine dioxide gas generated at this time is maintained at about 0.01 to 10 ppm.

The air compressor 20 is provided with a DC / AC power unit 23 so as to be driven by both the normal AC power source 21 and the DC power supplied from the battery 22, The commercial AC power source 21 is used and the power source of the DC battery 22 can be used in a place where commercial power is not supplied.

The contact type micro tonometer 50 is installed in the upper region of the solution storage tank 10 to display the pressure of the chlorine dioxide gas in the solution storage tank 10, ) Controls the operation of the air compressor 20 by generating an electrical ON / OFF control signal when the pressure inside the reaction tank 10 is equal to or higher than the set value, It is possible to secure the safety of the generating apparatus by setting the user to an appropriate pressure according to the use or specification of the generating apparatus.

On the other hand, when the pressure in the reaction tank 10 rises above the set value due to the abnormality of the discharge pipe 30, So that the air compressor 20 can be stopped.

A method of using the chlorine dioxide generating device of the present embodiment having such a constitution will be described.

According to recently reported data, it was reported that influenza A virus was infected with mouse at a low concentration of 0.03ppm for 15 minutes exposure to infectivity against virus using chlorine dioxide gas (Ogata N & Shibata T. 2008 J Gen Virol.), And all viruses were inactivated with or without Gram-positive, negative bacteria and coat on wet glass surface within 5 hours at 0.05ppm. (Morino H. et al. 2011 Effect of low-concentration chlorine dioxide gas against surface bacteria and viruses on a glass surface in wet environments. Lett Appl Microbiol doi: 10.1111 / j.1472-165X) Since low concentrations of chlorine dioxide gas can control a variety of microorganisms, including viruses, this device should be placed in the place where you want to disinfect As the concentration of chlorine dioxide gas increases at room temperature, the polyphenol oxidase activity increases as the concentration of chlorine dioxide gas increases at room temperature according to the food disinfection data of chlorine dioxide gas treatment of Chungnam National University food engineering department. . There was no significant difference in aerobic bacterial counts according to chlorine dioxide treatment concentration. However, at the low temperature condition, the control group showed difference of 3.72 × 08 CFU / g at 10th day and 1.66 × 07 CFU / g at 50 ppm. In yeast and mold, yeast and mold counts decreased as the concentration of chlorine dioxide treatment increased. Therefore, chlorine dioxide gas is said to help maintain a perishable food product for a long time. In this case, if the apparatus is installed in the food warehouse and operated to maintain the proper gas concentration, desired disinfecting effect can be easily obtained.
