A filter unit 20 for purifying the incoming polluted air, a circulation pump 30 for supplying chlorine dioxide contained in the storage tank 10 to the filter unit 20, and a mist catcher installed on the exit side of the filter unit 20 ( 40), a discharge pipe 14 installed in the mist catcher 40, and a driving fan 16 installed in the discharge pipe 14 may be included.

The storage tank 10 has a container shape having an accommodating space therein. The storage tank 10 may accommodate chlorine dioxide water therein. The size or shape of the storage tank 10 may be variously modified.

A drain pipe 18 for purifying contaminated air and discharging remaining chlorine dioxide water may be provided at the bottom of the storage tank 10 . By opening the drain pipe (18), it is possible to remove the contaminated water remaining in the storage tank (10).

The suction pipe 12 is a pipe structure through which the polluted air flows. The device may be provided with at least one suction pipe 12 . The size or the number of installations of the suction pipe 12 may be variously modified. The suction pipe 12 may be installed on the upper part of the storage tank 10 . The outer tip of the suction pipe 12 forms an inlet through which the polluted air is introduced. The suction pipe 12 is installed in communication with the storage tank 10 , and the contaminated air introduced through the suction pipe 12 may be introduced into the storage tank 10 .

As shown, a perforated pipe 13 is installed at the front end of the suction pipe 12 to extend into the storage tank 10 . The perforated pipe 13 may be integrally formed with the suction pipe 12 .

The perforated pipe 13 is disposed on the inner upper portion of the storage tank 10, the lower end is blocked, and the hole 15 is formed at regular intervals on the outer circumferential surface so that the polluted air is discharged.

Accordingly, the contaminated air introduced through the suction pipe 12 is discharged into the storage tank 10 through the hole 15 formed in the surface of the perforated pipe 13 . Contaminated air is discharged from the front surface of the outer circumferential surface of the perforated pipe 13 through the holes 15 evenly formed on the outer circumferential surface of the perforated pipe 13 , so that the polluted air can be more smoothly introduced into the storage tank 10 .

A filter unit 20 is installed at the upper end of the storage tank 10 . Accordingly, the contaminated air introduced into the storage tank 10 is connected to the upper part of the storage tank 10?? It is purified while passing through the filter unit 20 .

The circulation pump 30 is installed on one side of the circulation pipe 32 connecting between the filter unit 20 and the storage tank 10 to filter the chlorine dioxide water in the storage tank 10 through the circulation pipe 32. 20) can be supplied under pressure. When the circulation pump 30 is driven, the chlorine dioxide water accommodated in the storage tank 10 is supplied to the filter unit 20 through the circulation pipe 32 . Accordingly, the filter unit 20 may purify the contaminated air with the supplied chlorine dioxide water.

The filter unit 20 is installed in communication at the top of the storage tank 10 to form a passage through which the contaminated air passes, and a mist layer is formed inside by chlorine dioxide water and chlorine dioxide gas to purify the contaminated air passing through. has been The lower end of the filter unit 20 is installed in communication with the storage tank 10 , and the chlorine dioxide water purified from the polluted air in the filter unit 20 falls under the filter unit 20 and goes to the storage tank 10 . is recovered The specific structure of the filter unit 20 will be described in detail later.

The fog layer may refer to an area in which small decomposed chlorine dioxide water particles and chlorine dioxide gas generated when chlorine dioxide water is decomposed into small particles are mixed and gathered in the form of a mist.

In this device, since the filter unit 20 is vertically connected to the upper end of the storage tank 10, the chlorine dioxide water treated with the contaminated air in the filter unit 20 flows down the filter unit and is immediately recovered to the storage tank. Accordingly, foreign substances such as polluted residues are not generated in the process of treating polluted air, and wastewater purification is unnecessary.

A mist catcher 40 may be installed at the upper exit side of the filter unit 20 . The mist catcher 40 collects and removes particles of chlorine dioxide in the form of mist contained in the polluted air that has passed through the filter unit 20 . The chlorine dioxide water collected in the mist catcher 40 may be recovered to the storage tank 10 through the filter unit 20 . By going through the mist catcher 40, all of the chlorine dioxide water is recovered, and only the purified air can be discharged to the outside.

The driving fan 16 is installed in the discharge pipe 14 connected to the exit side of the mist catcher 40 to provide suction power for polluted air. Accordingly, when the driving fan 16 is operated, suction pressure is applied to the storage tank 10 through the mist catcher 40 and the filter unit 20 . Accordingly, external polluted air is sucked into the storage tank 10 through the suction pipe 12 connected to the storage tank 10 . The driving fan 16 may be installed in the suction pipe 12 , which is an inlet through which polluted air is introduced, in addition to the discharge pipe 14 .

In another embodiment, the driving fan may be rotated in the reverse direction to reverse the flow direction of the polluted air to the device. Accordingly, the polluted air generated at the driving fan position may be introduced into the filter unit to be purified and then discharged through the suction pipe. Accordingly, it is possible to freely change the inlet through which the polluted air is introduced into the outlet of the purified air and the outlet through which the purified air is discharged into the inlet of the polluted air. As described above, the present apparatus can purify polluted air in either direction by changing the flow of air in the forward or reverse direction by simply changing the rotational direction of the driving fan.

The air deodorization and purification apparatus of this embodiment may further include a concentration maintaining unit for maintaining the concentration of chlorine dioxide in the storage tank (10).

The concentration maintenance unit is a generator 50 for generating chlorine dioxide water by diluting chlorine dioxide with make-up water, a water tank 52 for storing make-up water to be supplied to the generator 50, and between the water tank 52 and the generator 50 A supply pipe 56 installed between the supply pump 54 for supplying make-up water and the generator 50 and the storage tank 10 installed on the pipeline 53 of ) may be included.

The generator 50 may produce chlorine dioxide water by, for example, generating chlorine dioxide gas and contacting it with the supplied make-up water. A gas generator 55 for generating chlorine dioxide gas may be provided inside the generator 50 .

The supply pump 54 is driven when necessary to supply the make-up water accommodated in the water tank 52 to the generator 50 .

The chlorine dioxide water produced in the generator 50 is supplied to the storage tank 10 through the supply pipe 56 and mixed with the chlorine dioxide water contained in the existing. Accordingly, it is possible to increase the concentration of the chlorine dioxide water accommodated in the storage tank 10 to an appropriate value.

Therefore, it is possible to maintain the concentration of chlorine dioxide water in the storage tank 10 above a certain value, and thus it is possible to prevent a decrease in the efficiency of purifying polluted air due to a decrease in the concentration.

In addition, the concentration maintaining unit may have a structure for purifying polluted air prior to the filter unit 20 using chlorine dioxide water supplied into the storage tank 10 .

To this end, as shown in FIG. 2, the concentration maintaining unit is connected to the supply pipe 56 and installed in the injection pipe 60 and the injection pipe 60 disposed on the inner upper portion of the storage tank 10 to spray chlorine dioxide water. It may further include a spray nozzle (62)

Accordingly, before the contaminated air flows into the filter unit 20 from the inside of the storage tank 10, chlorine dioxide water may be sprayed onto the contaminated air for purification treatment.

The injection pipe 60 may be disposed to form a closed curve in the form of a ring and wrap around the inlet of the filter unit 20 . A plurality of injection nozzles 62 may be installed at intervals along the injection pipe 60 . In this embodiment, the injection nozzle 62 may be installed to spray the chlorine dioxide water toward the injection pipe (60). Accordingly, chlorine dioxide water can be effectively sprayed into the contaminated air flowing into the filter unit 20 from the upper portion of the storage tank 10 .

The concentration maintaining unit may further include a collision plate 64 for colliding the chlorine dianide water sprayed from the injection nozzle 62 by being spaced apart from the injection pipe 60 .

The collision plate 64 may be fixedly installed in the injection pipe 60 while being spaced apart from the injection nozzle 62 by a predetermined distance. The ideal chlorine water sprayed from the injection nozzle 62 collides with the collision plate 64 to be finely decomposed into fine particles and to generate chlorine dioxide gas.

The chlorine dioxide water supplied to the storage tank 10 through the supply pipe 56 is injected into the upper space of the storage tank 10 through the injection nozzle 62 installed in the injection pipe 60 . The polluted air introduced into the upper part of the storage tank 10 is sprayed from the injection nozzle 62 and comes into contact with the chlorine dioxide particles and chlorine dioxide gas generated by the collision plate 64, and after primary purification treatment, the filter unit 20 ) can be introduced.

In this way, as the chlorine dioxide water is sprayed into the contaminated air through the concentration maintaining unit to perform the primary treatment and then the purified air is processed through the filter unit 20, the efficiency of the treatment of the contaminated air of the present apparatus can be further increased.

In this embodiment, the injection pressure of the chlorine dioxide water through the injection nozzle 62 may use the supply pressure of the supply pump 54 for supplying water to the generator (50). In another embodiment, in addition to the above structure, a pump (not shown) may be further installed on one side of the supply pipe 56 to which chlorine dioxide water is supplied. According to the driving of the pump, chlorine dioxide water may be injected at a high pressure through the injection nozzle 62 .

The chlorine dioxide water injection through the injection nozzle can be made when the chlorine dioxide supply pressure supplied to the injection pipe is high. When the chlorine dioxide supply pressure to the injection pipe is low, chlorine dioxide is discharged to the storage tank through the injection nozzle and only supply can be made.

In addition, as shown in FIG. 2 , the device is connected to the suction pipe 12 and disposed on the bottom of the storage tank 10 to discharge the contaminated air into the chlorine dioxide water inside the storage tank 10. The aeration pipe 65 may further include.

The aeration pipe 65 has a structure in which a plurality of holes 67 are formed, and polluted air is discharged in the form of bubbles in the chlorine dioxide water through the holes 67 . Contaminated air bubbles come into contact with the chlorine dioxide water while rising from the bottom of the storage tank 10 to the top. In this process, the polluted air can be purified by chlorine dioxide water.

As described above, by first aeration in the chlorine dioxide water accommodated in the storage tank 10 through the aeration pipe 65 and contacting the contaminated air with the chlorine dioxide water, it is possible to further maximize the purification treatment efficiency.

In the case of the structure including the aeration pipe 65, a separate suction fan (not shown) may be further provided to increase the suction pressure of the polluted air.

Contaminated air introduced into the storage tank 10 through the suction pipe 12 according to the operation of the driving fan 16 is introduced into the filter unit 20 to be purified. The filter unit 20 allows the polluted air to pass through the mist layer formed by the chlorine dioxide water, so that it can be purified more effectively.

Hereinafter, the structure of the filter unit according to the present embodiment will be described with reference to FIGS. 3 to 5 .

The filter unit 20 has at least one external pipe 21 , an external pipe 21 , the upper and lower ends are formed penetratingly, the lower end is installed in the storage tank 10 to extend vertically, and the upper end is installed in communication with the mist catcher 40 . It is spaced apart from the inner surface, is disposed in the inner center, is installed to extend in the axial direction, is connected to the circulation pump 30, and is installed in the inner tube 22 and inner tube 22 to which chlorine dioxide water is supplied, and chlorine dioxide water is supplied to the outer pipe 21 ) It may include at least one mist nozzle 23 to form a mist layer by spraying it inside.

In the present embodiment, at least one filter unit 20 may be provided so as to be installed in an appropriate number according to equipment specifications or purification treatment conditions. In addition, the length of the filter unit 20 or the number of mist nozzles 23 installed in the inner tube 22 may also be variously modified according to facility specifications or purification treatment conditions.

Accordingly, the device can be easily expanded or reduced by varying the number or length of the filter unit 20 to be installed. Therefore, it becomes possible to construct a facility more simply according to the required purification processing capacity.

The outer pipe 21 may be a cylindrical structure having an empty interior and an open upper and lower ends. The external pipe 21 is installed in communication with the storage tank 10 and the mist catcher 40, respectively. A flange 29 for coupling the storage tank 10 and the mist catcher 40 may be installed at the lower end and upper end of the outer pipe 21 , respectively.

In this embodiment, the distance between the outer pipe 21 and the inner tube 22 may be formed of 30mm to 350mm.

If the distance between the outer pipe 21 and the inner pipe 22 is less than 30 mm, the distance between the mist nozzle 23 and the inner surface of the outer pipe 21 is too short, so that chlorine dioxide sprayed from the mist nozzle 23 is (21) As it collides with the inner surface, it does not form particles and the mist layer is not properly formed while maintaining the liquid phase. Accordingly, the contact area between the polluted air and chlorine dioxide is reduced, and the purification efficiency is reduced.

If the distance between the outer pipe 21 and the inner tube 22 is greater than 350 mm, the size of the inner space of the outer pipe 21 becomes too large, so it is difficult to increase the injection pressure of the chlorine dioxide water, and the distance between the outer pipe and the inner tube is long. It is difficult to form a fog layer due to the weak collision force. Accordingly, it is difficult to densely form the fog layer inside the outer pipe 21, and the polluted air does not effectively contact the chlorine dioxide fog layer, so that the purification efficiency is lowered.

The inner tube 22 is spaced apart from the inner surface of the outer pipe 21, is disposed at the inner center, and extends in the axial direction. The lower end of the inner tube 22 is connected to the circulation tube 32 . In this embodiment, the inner tube 22 may extend into the storage tank 10 past the lower end of the outer pipe 21 and be connected to the circulation tube 32 .

A plurality of mist nozzles 23 are formed along the inner tube 22 . The mist nozzle 23 sprays the chlorine dioxide water supplied to the inner tube 22 in the form of fine particles to form a mist layer by the chlorine dioxide water particles and chlorine dioxide gas.

Accordingly, the contaminated air introduced into the filter unit 20 can be in contact with chlorine dioxide as much as possible while passing through the chlorine dioxide water mist layer of the outer pipe 21 to be purified.

The mist nozzle 23 may be formed at intervals along the axial direction of the inner tube 22 , for example. In addition, the mist nozzle 23 may be formed at intervals along the circumferential direction of the inner tube (22). Each of the mist nozzles 23 may be formed in the same position along the axial direction or formed in a zigzag form at a position shifted.

Chlorine dioxide water can be sprayed through the mist nozzle 23 uniformly arranged as a whole inside the outer pipe 21 . Accordingly, it is possible to form the fog layer in a uniform distribution as a whole in the inner space of the outer pipe 21 . Accordingly, polluted air passes through while in uniform contact with the chlorine dioxide mist layer anywhere in the outer pipe 21, thereby increasing the purification treatment efficiency.

4, the mist nozzle 23 may further include a horizontal slot 27 for widely spraying chlorine dioxide water in the horizontal direction. The horizontal slot 27 is formed by being dug through the injection hole 24 on the outer circumferential surface of the inner tube 22 and extends in a direction perpendicular to the axial direction of the outer pipe 21 to spread chlorine dioxide in the horizontal direction. has been

Here, the horizontal direction means a direction perpendicular to the vertical direction. That is, in a direction forming a right angle with respect to the vertically arranged outer pipe 21, it means a direction perpendicular to the traveling direction of the air passing through the outer pipe (21).

The horizontal slot 27 may be formed by cutting a straight line into the outer pipe 21 in the form of a trench groove. The depth or width of the horizontal slot 27 may be variously modified. The chlorine dioxide water particles injected from the injection hole 24 of the mist nozzle 23 may be diffused in the horizontal direction by the horizontal slot 27 .

Accordingly, the mist nozzle 23 can spray the chlorine dioxide water so as to spread widely in a direction perpendicular to the traveling direction of the polluted air. Accordingly, the contaminated air that rises vertically along the outer pipe 21 passes the chlorine dioxide water particles spread in the horizontal direction, so that it can be in contact with a larger area.

In addition, chlorine dioxide water is sprayed while spreading in a direction perpendicular to the moving direction of the contaminated air through the mist nozzle 23, so that the chlorine dioxide water is blocking the contaminated air. Accordingly, the contaminated air must pass through the chlorine dioxide water particle layer horizontally spread in the outer pipe 21 in the process of moving upward. Therefore, by making the polluted air in contact with chlorine dioxide water in the outer pipe 21 seamlessly, it becomes possible to increase the purification treatment efficiency.

The mist nozzle 23 of this embodiment has a structure that can make chlorine dioxide water into fine particles.

As shown in Figure 5, the mist nozzle 23 is formed so that the inner diameter gradually expands from the inner surface of the injection hole 24 toward the outside, the inclined surface 25 for spreading chlorine dioxide water, and the inclined surface 25 outside It may include a stepped portion 26 for finely splitting the injected chlorine dioxide water into fine particles that are formed by digging the inner circumferential surface so as to be stepped on.

Accordingly, the chlorine dioxide water sprayed through the injection hole 24 is primarily granulated while being widely spread by the inclined surface 25 . And, chlorine dioxide water particles pass through the stepped portion 26 on the outside of the inclined surface 25, the particles are more finely split and generated into smaller particles, at this time chlorine dioxide gas dissolved in the chlorine dioxide water is generated.

That is, the chlorine dioxide water particles that spread widely collide with the stepped portion 26 while passing through the sharply bent stepped portion 26. smaller and gasification occurs.

Accordingly, the mist nozzle 23 splits the chlorine dioxide water into fine particles and generates gas. Accordingly, it is possible to form a mist layer in which chlorine dioxide water and chlorine dioxide gas in particulate form are suspended inside the outer pipe 21 .

In addition, in order to maximize the mist layer, the filter unit 20 of this embodiment is installed on the inner tube 22 and extended to the mist nozzle 23, the support 35, the support 35 is installed at the tip of the mist nozzle ( 23) It may further include a collision rod 37 disposed on the outside and collided with the chlorine dioxide water sprayed from the mist nozzle 23 to decompose the chlorine dioxide water into fine particles.

The collision rod 37 may be arranged in alignment with the center of the injection hole 24 of the mist nozzle 23 .

Accordingly, chlorine dioxide water sprayed from the mist nozzle 23 is primarily decomposed into small particles while colliding with the collision rod 37 to generate chlorine dioxide gas. In addition, the chlorine dioxide water can easily collide with the inner wall of the stepped portion 26 and the outer pipe 21 as the injection angle is bent as it collides with the collision rod 37 . Accordingly, it is possible to effectively form the chlorine dioxide water into a mist layer in the form of small particles and gas.

In this embodiment, the collision rod 37 may have a hemispherical shape with a surface facing the mist nozzle. Accordingly, the chlorine dioxide water sprayed from the injection hole 24 of the mist nozzle collides with the collision rod 37 and can be dispersed at a wider angle. Therefore, it is possible to increase the generation of particulates and gases by effectively colliding the chlorine dioxide water with the stepped portion 26 as well as the external pipe 21 .

As described above, this device forms a fog layer by chlorine dioxide water inside the filter unit 20 and purifies the polluted air while passing it through the fog layer, thereby maximizing the contact area between polluted air and chlorine dioxide to effectively remove polluted air. can be purified.

As described above, although exemplary embodiments of the present invention have been illustrated and described, various modifications and other embodiments may be made by those skilled in the art. All such modifications and other embodiments are intended to be contemplated and included in the appended claims without departing from the true spirit and scope of the present invention.
