The present invention relates to a gas purifying apparatus using ozone water, and more specifically, to treat and deodorize odors and VOC gas generated at industrial sites using ozone water and to deodorize existing activated carbon adsorption towers and microorganisms, and RTO (direct combustion facility). Compared to the chemical treatment method and the chemical treatment method, and the gas purification device using ozone water can significantly reduce the cost and power consumption when constructing and using the device.

As the industry develops, the environmental pollution problem is an important issue that should not be left anymore. According to a recent press release, the most serious environmental pollution is air pollution, followed by water pollution, pollution by hazardous chemicals, pollution by waste, and soil pollution.

Odors and VOC gases inevitably generated during operation or production of products in industrial sites contain harmful substances and are often accompanied by severe odors. Such waste gases include components such as ammonia, trimethylamine, methyl mercaptan, methyl sulfide, methyl disulfide, and the like.

At present, the odor and VOC gas treatment method widely adopted in industrial sites is to use activated carbon adsorption towers and microorganisms, RTO (direct combustion facilities) and chemical purifiers with chemicals.

However, when using this method, it is expensive to equip the gas purifier. Furthermore, after a certain time, there is a problem in that the maintenance cost is high because the consumption of adsorbents and fuels and chemicals used in treating odor and VOC gas is large. In addition, there must be a complex facility for reacting with odor and VOC gas, there is a problem that the power consumption for driving these facilities also increases. Therefore, it is necessary to develop a device that can effectively deodorize while reducing costs and power consumption.

The present invention is to solve the above problems, by using the ozone water (ozone water) to deodorize the odor and VOC gas generated in the industrial site, etc., it is possible to increase the efficiency compared to the conventional treatment method, and required for the construction and use of the device It is an object of the present invention to provide a gas purifying apparatus using ozone water, which can reduce the cost.

In order to achieve the above object, the present invention provides a gas purification apparatus using ozone water having the following constitution.

An apparatus main body having an odor and VOC gas processing space formed therein;

An inlet device connected to a lower portion of the main body of the apparatus and allowing odor and VOC gas to be treated to flow into the odor and VOC gas treatment space;

A discharge unit connected to an upper portion of the apparatus main body and configured to discharge treated gas;

An ozone water spraying unit protruding from an inner wall of the apparatus main body and spraying ozone water toward the odor and VOC gas that enters through the inflow apparatus and moves toward the discharge unit; And

And an ozonated water supply device for generating ozone water and supplying the ozone water to the ozone water spraying unit.

Here, the ozone water spraying unit,

An ozone water moving tube spaced apart from each other along the height direction in the odor and VOC gas treatment space; And a plurality of partition walls disposed adjacent to each ozone water moving tube.

In addition, the ozone water moving pipes and the partition walls are preferably projected alternately from the left and right inner walls of the device body. The protruding length is not particularly limited and may be such that the upward movement of the waste gas can be made at an appropriate speed.

In a preferred embodiment, ozone water is received at the bottom of the device body and the ozone water supply also supplies ozone water to the bottom of the device body. The inlet device also includes a microbubble device installed inside the device body so as to be submerged in ozone water accumulated at the bottom of the device body, and the microbubble device allows odor and VOC gas to be supplied into the device in the form of fine bubbles.

Ozone water is a solution of ozone gas dissolved in water. Ozone is the second strongest oxidizing material in nature after fluorine. Therefore, organic and inorganic substances present with ozone are oxidized by ozone, and the oxidizing power of ozone is larger as ozone concentration increases. These oxidative powers have a variety of functions such as sterilization, bleaching and decomposition of substances, and do not leave residual toxicity. Therefore, it is also widely used to decompose microorganisms contaminating water or residual pesticides remaining in foods.

When such ozone is dissolved in water and changed into ozone water, it has a characteristic of reducing components such as ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide and methyl disulfide, which constitute odor and VOC gas. In the present invention, this characteristic is used.

There are two ways to make ozone water: one is to produce ozone gas outside the water, and then to dissolve it in water and another is to generate ozone directly in the water. Therefore, in the present invention, it is irrelevant whether ozone is produced by any known method.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. In the description of each embodiment, the same reference numerals are given to the same configurations.

1 is a schematic configuration diagram of a gas purifying apparatus 1 using ozone water according to a first embodiment of the present invention, and FIG. 2 is an enlarged view illustrating main parts of FIG. 1.

As shown in the figure, the gas purifying apparatus 1 using ozone water of the present invention is largely provided in the apparatus main body 10 and the apparatus main body 10, and the inlet part 12 which forms the outflow and inflow space of odor and VOC gas. And an ozone water spraying unit 20 formed in a large number in the discharge unit 17 and the apparatus main body 10.

In addition, since the gas purifier 1 uses ozone water, another ozone water supply device 30 for generating ozone water is also formed.

The apparatus main body 10 is a part constituting the body of the gas purifying apparatus 1. The odor and VOC gas treatment space 10a in which the odor and VOC gas are deodorized by ozone water is formed inside the apparatus main body 10. Therefore, the larger the size of the apparatus main body 10, the faster it is possible to deodorize a larger amount of odor and VOC gas. In the lower region of the malodorous and VOC gas processing space 10a, a guide plate 15 is disposed obliquely inclined to guide the malodorous and VOC gas upward.

The waste gas is purified while moving upward from the bottom of the processing space 10a. Therefore, the inflow part 12 penetrates the wall of the apparatus main body 10 below the apparatus main body 10, and is extended inward from the apparatus 1 exterior. The inflow part 12 is provided with the inflow fan 14 which allows the odor and VOC gas to flow into the odor and VOC gas processing space 10a in the apparatus main body 10 easily, quickly and more. Although not shown, a discharge fan may be installed in the discharge unit 17.

Whereas the inlet 12 is formed at the bottom of the apparatus body 10, the outlet 17 is formed at the top of the apparatus body 10. The air discharged through the discharge unit 17 is a gas that has completed the deodorizing treatment in the odor and VOC gas processing space 10a.

On the other hand, the ozone water spraying unit 20 protrudes from the inner wall of the main body 10 to the odor and VOC gas treatment space 10a, and moves the odor and VOC gas moving from the inlet 12 toward the outlet 17. Ozone water is sprayed to deodorize odor and VOC gas. The ozone water spraying unit 20 is connected to the ozone water supply device 30 described above by the ozone water supply line 24 to receive ozone water. The ozone water spraying unit 20 is formed in the ozone water moving tube 21 through which the ozone water provided from the ozone water supply device 30 moves, and in the ozone water moving tube 21 along the longitudinal direction of the ozone water moving tube 21, and causes odors and VOCs at the corresponding positions. And a plurality of ozone water spray nozzles 22 for spraying ozone water towards the gas.

The ozone water supply line 24 is provided with a valve 23. The valve 23 may be mechanical or an electronic solenoid. And if the on / off operation is automatically controlled by the control unit will be convenient to use.

The ozone water moving tube 21 of the ozone water spraying unit 20 may be one, but the ozone water moving tube 21 may have various directions along the height direction in the malodorous and VOC gas treatment space 10a so that more malodor and VOC gas may come into contact with the ozone water. Dogs are spaced apart from each other and are installed in a zigzag multistage. On the other hand, the ozone water spraying unit 20 protrudes at an angle slightly downward with respect to the horizontal to facilitate the upward movement of the gas and the downward movement of the sprayed ozone water.

In the odor and VOC gas treatment space 10a, a partition wall 25 protruding and extending in parallel with the ozone water movement pipe 21 is formed adjacent to the upper portion of each ozone water movement pipe 21. The partition wall 25 extends from one end to the other end in the front-back direction (the drawing direction in the drawing) of the apparatus main body 10. Thus, the septum 25 prevents gas from moving up through a path other than a zigzag path. Therefore, the gas is prevented from rising upward without being sufficiently in contact with the ozone water to be sprayed. That is, since the ozone water moving pipe 21 and the partition walls 25 are also arranged in a zigzag manner to make the flow path of the malodor and VOC gas sufficiently long, the malodor and VOC gas are zigzag as shown by the arrows in FIG. In other words, it can make more contact with ozone water while forming a 'c' shaped movement path.

An end portion of the ozone water spray nozzle 22 extends radially, and has a structure in which ozone water can be spread while spreading.

A water evaporation prevention filter 19 is formed at the top of the apparatus main body 10 and immediately before the discharge unit 17 to filter only ozone water that can be discharged through the discharge unit 17 together with the gas, so that only the gas can be discharged. To help.

Meanwhile, the ozone water supply device 30 supplies ozone water to the bottom of the apparatus main body 10 through the ozone water supply line 25b. And the microbubble device 42 which functions as a malodor and a VOC gas micro supply apparatus is extended from the inflow part 12 to the center part of the apparatus main body 10. As shown in FIG. The microbubble device 42 has fine pores formed on its surface, through which waste gas is ejected in the form of fine bubbles, thereby increasing the contact area with ozone water. The microbubble device 42 is supplied from the ozone water supply device 30 and immersed in ozone water stored in the bottom portion of the device main body 10. Therefore, when the waste gas flows into the apparatus main body 10 through the microbubble device 42, the waste gas is once in contact with the ozone water, thereby increasing the treatment efficiency.

Although not shown in the drawing, a discharge port and a recovery device for discharging and recovering the ozone water received may be installed at the lower part of the apparatus main body 10.

The operation of the gas purifying apparatus 1 having the above-described configuration will be described below.

First, the inflow fan 14 is operated to introduce odor and VOC gas generated in a factory facility or the like into the apparatus main body 10 through the microbubble device 42. The introduced odor and VOC gas are first purified by contacting ozone water around the microbubble device 42. After the ozone water is moved away along the guide plate 15, and the zigzag moving upwards and continues to rise.

While the malodor and VOC gas are moving, ozone water provided from the ozone water supply device 30 flows along each ozone water moving pipe 21 through an open valve 23. The ozone water is then spread while spreading widely through a plurality of ozone water spray nozzles 22 installed in each ozone water moving pipe (21). Therefore, the odor and the VOC gas moving in a zigzag manner are deodorized in contact with the ozone water to be sprayed.

The ozone water after contact with the malodor and the VOC gas flows through the partition wall 25 by gravity, collects in the lower part of the apparatus, and is recovered.

On the other hand, the treatment time and speed of the odor by ozone water and the deodorization of VOC gas vary depending on the amount and concentration of the ozone water sprayed. As in the present embodiment, when ozone water is accumulated at the bottom and is also supplied from the ozone water moving tube 21 to be treated twice, the purification treatment effect is great, but since ozone water must be supplied to the bottom of the apparatus, More and more complex. However, if the concentration of the deodorizing purifying gas is not high, such a double treatment may not necessarily be necessary.

Therefore, in the second embodiment of the present invention as shown in FIG. 3, the structure for supplying ozone water from the ozone water supply device 30 to the lower portion of the apparatus main body 10 is removed. The ozone water shown in the figure is ozone water which has fallen from above. Therefore, this is different from the case of the first embodiment in which the microbubble device 42 is immersed in ozone water. In this case, the purification process can be carried out at a relatively low cost and facilities.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto, and various modifications may be made. Therefore, it is to be understood that the scope of the present invention is defined by the appended claims.

As described above, according to the present invention, it is possible to deodorize the odor and VOC gas generated in a factory or the like by using ozone water, away from the conventional treatment method.

Therefore, a simple installation can be achieved. In addition, the cost and power consumption of building or using the device can be significantly reduced.
