Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the present invention is not limited to the embodiments described herein, but may be embodied in many different forms. In addition, the reference numerals denoted below denote those shown in Fig. 1 according to the embodiment of the present invention. However, the reference numerals shown in the drawings of Figs. 7 and 8 are peculiar to each invention and are not related to the present invention.

As shown in FIG. 1, the sterilizing and deodorizing apparatus of the present invention having the function of maintaining the concentration of chlorine dioxide (ClO 2 ) gas and circulating the chlorine dioxide solution has a contaminated air inlet 100, A device 200, a chlorine dioxide neutralizing device 300 and a purified air supply port 600. The dehumidifying devices 400 and 500 are added as needed.

Next, the operation relationship of the above-described apparatuses will be described.

(1) Polluted air intake (100)

So that contaminated air is sucked from a space requiring purification. This configuration sucks air contaminated by a blower or the like, removes various kinds of dust and suspended matter through the filter 101 and the like as needed, and sucks only the contaminated air. Of course, the filter 101 may be periodically cleaned or replaced, and there is no particular need to limit the components or size thereof.

(2) Disinfection and deodorizing device (200)

And the contaminated air is sterilized and deodorized.

The sterilization and disinfection apparatus 200 is configured such that the chlorine dioxide solution stored in the lower portion of the apparatus 200 is first circulated by the circulation pump 210 to the apparatus 200 through the spray nozzles 211, 200) (hereinafter, referred to as a "first configuration").

The apparatus 200 includes a sodium hypochlorite (NaClO 2 ) reservoir 220 and an acid (organic acid and inorganic acid) reservoir 230, and a mixer for mixing the solutions supplied from the reservoirs 220 and 230. (Hereinafter, referred to as 'second configuration') in which the mixed solution mixed in the mixer 250 is injected to the lower side of the apparatus 200. The supply of the solution from the reservoirs 220 and 230 to the mixer 250 is performed by the air pump 240 and the solenoid valve 241.

Also, the concentration of the chlorine dioxide solution is adjusted by adjusting the concentration of the supplied chlorine dioxide solution according to the size of the used space and the environment, and using it. For example, when 1.0 ml of 1.0 ml of water is mixed with 1.0 ml of water / chlorine dioxide solution, it becomes 1 ppm, and when chlorine dioxide gas is 2.8 mg / m3, it becomes 1 ppm.

In the first operation of the apparatus 200 of the present invention, the chlorine dioxide is supplied by the second configuration, but after the operation for a predetermined period of time, the chlorine dioxide is supplied only by the first configuration, The configuration works together to supply chlorine dioxide.

In the middle part of the sterilizing and disinfecting and deodorizing apparatus 200, a filling layer 260 made of a material such as PVC, which is not corroded by chlorine dioxide, is made and the sterilized disinfection and deodorization is more effective .

(3) Chlorine Dioxide Neutralization Apparatus 300

In the process of mixing the contaminated air and the chlorine dioxide gas into the air supplied from the sterilizing / disinfecting and deodorizing apparatus 200, residual odor of the acid is left. The chlorine dioxide neutralization apparatus 300 is a device for removing the residual odor of such acidity and neutralizing chlorine dioxide.

The sterilization and disinfection apparatus 300 is configured such that the alkaline solution stored in the lower part of the apparatus 300 is sprayed downward by the spray nozzle 311 from above the apparatus 300 by the circulation pump 310 (Hereinafter referred to as " third configuration ").

Secondly, the alkaline solution reservoir 320 is provided on one side of the apparatus 300, and the solution supplied from the alkaline solution reservoir 320 is sprayed to the lower side of the apparatus 300. In this case, (Hereinafter, referred to as a "fourth configuration"). Of course, a separate spray nozzle may be used. The supply of the solution from the alkaline solution reservoir 320 to the injection nozzle 311 is performed by the air pump 340 and the solenoid valve 341.

In the initial operation of the apparatus 300 of the present invention, the alkaline solution is supplied by the fourth configuration, but after the operation for a predetermined time, the alkaline solution is supplied only by the third configuration, 4 configuration work together to supply the alkaline solution.

A filling layer 360 made of a material such as PVC, which is not corroded with an alkaline solution or chlorine dioxide, is formed in the middle of the chlorine dioxide neutralizing device 300, and the remaining odor of the product is removed , And to effectively neutralize chlorine dioxide.

(4) Purge air supply port 600

And supplies the purified air, which has been purified through the sterilizing / sterilizing / deodorizing device 200 and the like, to a space requiring purification.

1 shows that the purified air supply port 600 is connected after passing through the chlorine dioxide neutralizing device 300. However, the purified air supply port 600 is directly connected to the sterilization / disinfection / deodorizing device 200 without passing through the chlorine dioxide neutralizing device 300 It is possible.

When connected via the chlorine dioxide neutralizing device 300, the odor of the remaining acid in the purified air which has been sterilized and disinfected and deodorized is removed, and purified air, which has undergone neutralization of chlorine dioxide gas, .

When the purified air supply port 600 is directly supplied through the sterilizing / disinfecting / deodorizing apparatus 200, since the chlorine dioxide gas remains, the contamination source can be directly sterilized and deodorized. Since the chlorine dioxide gas has a very fast diffusion rate in the air, the contamination source can be purified in a short time.

In addition, a blower may be installed in the purified air supply port 600, or may be connected to an air conditioning system such as an air conditioner or a duct to clean a large space in a short time. In particular, when purifying air is supplied to a pig farm or a poultry farm, a heat source for temperature control may be passed. In the case of pigs or chickens, if there is a sudden change in the indoor air, there is a possibility of causing a respiratory disease. To prevent this, the above configuration may be added.

(5) Dehumidifying device (400, 500)

Various dehumidifying devices 400 and 500 can be installed between the sterilizing / sterilizing / deodorizing device 200 and the chlorine dioxide neutralizing device 300 and between the chlorine dioxide neutralizing device 300 and the purified air supply port 600.

By providing such a dehumidifying device, sterilization and deodorization can be more surely performed.

Next, the method for maintaining the concentration of the chlorine dioxide solution of the present invention and operating the sterilizing and deodorizing apparatus having air circulation function will be described in detail.

end. The polluted air intake step (first step)

The first step is a step of sucking the polluted air from the pollution source through the polluted air intake port 100. Then, the contaminated air intake port 100 is removed with various dusts and floating matters. The filter 101 may be installed so as to be easily cleaned with water as needed.

I. Disinfection and deodorization phase (2nd stage)

The second step is the disinfection and deodorization step.

The second step is to separate the sodium chlorate (NaClO 2 ) storage tank 220 and the acid (organic acid and inorganic acid) storage tank 230, which are provided at one side of the sterilizing and disinfecting and deodorizing apparatus 200, Disinfecting and deodorizing the contaminated air sucked from the first step by injecting a chlorine dioxide solution of a high concentration through the mixer 250 which mixes the solution supplied through the pump 240 and the solenoid valve 241, (Hereinafter referred to as a " chlorine dioxide supply step ").

According to the second configuration, the chlorine dioxide solution is stored in the lower portion of the sterilizing / disinfection / deodorization apparatus 200 when chlorine dioxide is produced and supplied through the mixer 250 for a predetermined period of time. The chlorine dioxide solution thus stored is injected into the lower portion of the sterilizing / sterilizing deodorizer 200 by the above-described constitution 1 to sterilize and disinfect the polluted air sucked from the first stage (hereinafter referred to as "chlorine dioxide input Step ").

The chlorine dioxide supplying step and the chlorine dioxide supplying step may be performed separately or may be performed together.

At this time, the chlorine dioxide input step according to the first constitution and the progress of the chlorine dioxide supply step according to the second constitution can be suitably operated in order to keep the concentration of the chlorine dioxide solution to be supplied constant.

That is, when the chlorine dioxide solution is sprayed in the chlorine dioxide supplying step according to the second configuration, the solution supplied from the sodium chlorite (NaClO 2 ) storage tank 220 and the acid (organic acid and inorganic acid) By adjusting, the desired concentration of chlorine dioxide can be produced. For example, when sodium chloride (NaClO 2 ) solution is supplied at 9.3 ml / min and sulfuric acid solution is supplied at 3.3 ml / min, a chlorine dioxide solution of about 1,000 ppm is produced.

Next, in order to provide a predetermined concentration of chlorine dioxide in the sterilizing / disinfecting / deodorizing step, for example, in the chlorine dioxide adding step according to the first constitution, the concentration of chlorine dioxide stored in the lower portion of the sterilizing / Can be achieved by adjusting the amount of the sodium chlorate and the acid solution in the chlorine dioxide supplying step according to the second constitution.

For example, when a chlorine dioxide solution of 100 ppm is to be introduced in the disinfection and deodorization step, sodium chlorite (NaClO 2 ) is added depending on the concentration of the chlorine dioxide solution stored in the lower part of the apparatus 200, By adjusting the supply amount of the solution and the sulfuric acid solution, the concentration of the chlorine dioxide solution can be kept constant.

Solution concentration (1) Concentration 60 ppm 70ppm 80 ppm 90 ppm 100 ppm (2-1) Solution 0.374 ml / min 0.279 ml / min 0.186 ml / min 0.093 ml / min 0ml / min (2-2) Solution 0.134 ml / min 0.1 ml / min 0.067 ml / min 0.033 ml / min 0ml / min Final concentration 100ppm 100ppm 100ppm 100ppm 100ppm

The concentration (1) represents the concentration of chlorine dioxide stored in the lower part of the apparatus 200 (when the amount of chlorine dioxide stored in the lower part of the apparatus 200 is 1 L), and the solution (2-1) Represents the supply amount of sodium chlorite (NaClO 2 ), and (2-2) represents the supply amount of sulfuric acid.

The adjustment of the supply amount as described above can be performed by adjusting the amount of sodium chlorite (NaClO 2 ) and the amount of the acid solution (not shown) based on the information obtained by a sensor (not shown) for measuring the concentration of the chlorine dioxide solution stored in the lower part of the apparatus 200 It can be done simply by adjusting the supply amount.

The injection nozzles 211 and 212 are preferably made of a material such as PVC, PP, Teflon, and platinum which is not corroded by chlorine dioxide.

In addition, a filling layer 260 made of a material such as PVC, which is not corroded by chlorine dioxide, is formed in the middle portion of the sterilizing and disinfecting and deodorizing apparatus 200, and the contaminated air passes through this portion, .

All. The first dehumidifying step (the third step)

In the third step, a dehumidifying device 400 is installed between the sterilizing / deodorizing device 200 and the chlorine dioxide neutralizing device 300 to remove the moisture of the purified air from the sterilizing / .

By removing the moisture in this way, the neutralization efficiency in the next step of chlorine dioxide neutralization (step 5) can be increased.

As the dehumidifying device 400 used at this time, it is preferable to use a filter which can be reused after being cleaned, and which can be semi-permanently used.

Of course, this step is not an essential constitution in the present invention.

la. Chlorine Dioxide Neutralization Step (Step 4)

The fourth step is a step of neutralizing the residual odor of the acids contained in the purified air that has undergone the second or third step and the chlorine dioxide gas.

Of course, this step is not an essential configuration in the present invention. This process may be unnecessary depending on the environment of the pollutant source that needs purification. For example, it is desirable to directly purify chlorine dioxide in an environment where a person such as a sewage end treatment plant or a plant or animal is not inhabited. In such a case, the fourth step may be omitted.

In the fourth step, the alkali solution supplied through the air pump 340 and the solenoid valve 341 is injected from the alkali solution reservoir 320 provided at one side of the chlorine dioxide neutralizing apparatus 300, And neutralizing the purified air supplied from the second or third step (hereinafter, referred to as 'alkali solution supply step') by injecting into the lower portion of the chlorine dioxide neutralizing apparatus 300 through the nozzle 311.

In addition, according to the fourth configuration, when a certain period of time has elapsed while the alkali solution is supplied, the alkali solution is stored in the lower portion of the chlorine dioxide neutralization apparatus 300. Then, the alkaline solution thus stored is injected into the lower part of the chlorine dioxide neutralization apparatus 300 by the above-described constitution 3 to neutralize the purified air supplied from the second or third step (hereinafter referred to as " Step ").

The alkali solution supplying step and the alkaline solution supplying step may be performed separately or may be performed together.

Thus, in the fourth step, after the second step or the third step, the purified odor contained in the purified air is neutralized with the residual odor of the acid and chlorine dioxide to obtain purified air.

hemp. Secondary dehumidification step (fifth step)

The fifth step is a step of removing moisture from the purified air through the chlorine dioxide neutralizing apparatus 300.

This step is performed in the same manner as in the third step, in which moisture caused by the alkaline solution is also removed.

bar. The purge air supply step (sixth step)

The sixth step is a step of supplying the purified air having passed through all the steps to a space or the like that requires it.

For example, in the case of a space having a person, animal or plant or animal, such as a restaurant, a hospital, an airport, a barn, etc., it is preferable to carry out the fifth step of chlorine dioxide neutralization. However, in the case of contaminated facilities such as sewage treatment facilities (resource cavitation facilities) and sewage terminal treatment plants, it is not necessary to go through the fifth step of chlorine dioxide neutralization step.

At this stage, when the air conditioning system such as the air conditioner and the duct is used through the blower, the purified air can be supplied more effectively.
