Hereinafter, the present invention will be described in detail with reference to the drawings. In the present invention, the wet type fine dust removing apparatus shown in the drawings will be described as an example, but the present invention is not limited to the wet type fine dust removing apparatus shown in the drawings.

Various embodiments are described herein that can support the present invention. The components and features applied to different embodiments may be selectively applied thereto, and a detailed description thereof will be omitted.

FIG. 1 shows a wet type fine dust removing apparatus 100 according to an embodiment of the present invention.

Referring to the drawings, a wet type fine dust removing apparatus 100 includes an air inlet 110; A water particle jetting section 120; A water particle recovery unit 130; A water tank 140; And a blowing fan 160. The wet type fine dust removing apparatus 100 can adsorb fine dust having a particle size of 10 μm or less by adsorbing it on a carrier having a very large specific surface area by coagulating it with high humidity. For this, the water particle collecting part 130 may include a plurality of carriers 131 collecting the water particles adsorbed by fine dust.

The inflow air containing the fine dust may be introduced into the air inlet 110. The water particle spraying section 120 can supply water particles to the inflow air so as to adsorb fine dust contained in the inflow air.

The water particle collecting unit 130 can collect the water particles adsorbed by the fine dust. The water tank 140 can supply water to the water particle spraying unit 120 and recover and store the water particles adsorbed by the fine dust from the water particle collecting unit 130. The air blowing fan 160 may draw air from the inlet air to form an air flow so that purified air from which fine dust is removed is discharged. At this time, the water particle collecting unit 130 may include a plurality of carriers 131 collecting the water particles adsorbing fine dust.

Therefore, by collecting the fine dust contained in the introduced air as fine water particles and adsorbing the fine particles on the carrier 131 having a large specific surface area, the fine dust removing performance can be improved by a simple structure.

The inflow air containing the fine dust may be introduced into the air inlet 110. Fine dust may be contained in the inflow air flowing through the air inlet 110. The fine dust is adsorbed by the water particles injected from the water particle injecting section 120, (130). At this time, the fine dust is removed from the inflow air, and the air from which the fine dust is removed can be discharged through the air discharge port 160 through the water particle recovery unit 130.

At this time, the air inlet 110 and the air outlet 160 are disposed in the same indoor space, and the air including the dust in the indoor space flows through the air inlet 110, and the air from which the fine dust is removed passes through the air outlet 160 And the operation is repeated, so that the fine dust can be removed from the room air.

At this time, the blowing fan 160 sucks the inflow air through the air inlet 110 to form an air flow so that the purified air from which the fine dust is removed is discharged through the air outlet 160. Further, the blowing fan 160 can control the operation speed according to the concentration of the fine dust in the air, thereby adjusting the amount of the introduced air. For this purpose, a dust sensor for measuring the concentration of the fine first in the air may be additionally provided. In this case, a separate control unit is provided, and the control unit can control the operation of the blowing fan 160 according to the concentration of the dust measured by the dust sensor.

On the other hand, the air flow from the air inlet 110 to the air outlet 160 can be horizontally aligned. In this case, the internal structure of the wet type fine dust removing apparatus 100 can be simplified.

In addition, the water particle collecting unit 130 may be disposed so as to be in contact with the end of the water particle spraying unit 120 according to the air flow. In this case, the water particles adsorbing the fine dust can be effectively recovered.

In another embodiment, the cross-sectional area of the jetting space through which the water particles are injected may be smaller than the cross-sectional area of the water particle collecting portion 130. In addition, the cross-sectional area of the space in which the air blowing fan 150 on the side of the air outlet 160 is provided may be substantially equal to the cross-sectional area of the water particle collecting part 130. In this case, the air flow passing through the water particle spraying unit 120 can evenly contact the entire surface of the water particle collecting unit 130, thereby improving water particle collecting performance.

1 shows an embodiment in which the air flow from the air inlet 110 to the air outlet 160 is horizontally aligned. However, the present invention is not limited to this, and a bent structure or a vertical structure is also possible.

The water particle spraying section 120 can supply water particles to the inflow air so as to adsorb fine dust contained in the inflow air. The water particle spraying unit 120 can spray the water supplied from the water tank 140 by ultrasonic waves.

In this case, the water tank in which the water in the water tank 140 is stored is arranged at a higher level than the ultrasonic wave generating unit, water is supplied to the ultrasonic wave generating unit from the water tank by the water supply controlling unit as much as necessary for the ultrasonic wave generating unit, Water can be generated from the unit by ultrasonic jetting by ultrasonic waves. At this time, the water particles injected by the ultrasonic wave generating unit may be discharged to the injection space of the water particle spraying unit 120 through a separate conduit and / or an outlet.

In another embodiment, the water particle spraying unit 120 can spray water stored in the water tank 140 through a nozzle to atomize the water particles into the spraying space and discharge the water. At this time, the nozzles may be disposed at the upper portion of the jetting space and form water screens from the upper portion into the jetting space, and the water particles may be jetted.

To this end, the water particle sprayer 120 may include a conduit, a nozzle unit, and / or a pump. The conduit may be connected to the upper portion of the jet space through which the water particles are jetted from the water tank 140. In addition, the nozzle unit is connected to the end of the conduit and can inject water supplied from the water tank 140 into the injection space. In addition, the pump can draw water from the water tank 140 to the nozzle unit when the nozzle unit is installed on the top of the water tank 140.

On the other hand, the nozzle unit can be arranged to cover the upper area of the cross section perpendicular to the air flow direction of the jetting space so as to sufficiently cover the upper space of the jetting space. In this case, the nozzle unit may be disposed at an upper portion of the jetting space to form a water screen from the upper portion of the jetting space to the jetting space and jet water particles. Accordingly, fine particles passing through the spray space can be effectively adsorbed by the water particles sprayed into the spray space.

The water particle spraying part 120 is connected to the water tank 140 at one end of the water particle spraying part 120. The water particle spraying part 120 is connected to the water tank 140, May be provided.

At this time, the water tank 140 can be separated from the housing 101. The inlet of the water particle spraying unit 120 and the water outlet 141 of the water tank 140 are connected to each other, 140 to supply water particles or water to the water particle spraying unit 120. In this case, the inlet of the water particle spraying unit 120 is provided with a cap which is opened when the water tank 140 is pushed from the outside, and is opened only when the water tank 140 is coupled. When the water tank 140 is separated, 120 may be closed.

At this time, a water particle generator including a separate ultrasonic generator may be included between the water outlet 141 of the water tank 140 and the inlet of the water particle sprayer 120.

The water particle collecting unit 130 can collect the water particles adsorbed by the fine dust. For this, the water particle collecting unit 130 may include a carrier 131 that is accommodated in a space defined by a partition wall or the like. At this time, fine particles passing through the water particle collecting part 130 by the carriers 131 can collect the water particles adsorbed.

The carrier 131 of the water particle collecting part 130 may be a ball-shaped pleated ball having a pleated structure formed by bending a thin sheet. The pleated ball may have a shape as shown in Fig. The pleated ball is formed of a PVC material so that the pleated ball can be easily formed at a low cost.

The pleated ball having a pleated structure as shown in the figure has a structure capable of maximizing the specific surface area per unit volume, and the flow of the fine dust can be made turbulent by the shape of the pleated ball. In addition, it is possible to maximize the time for allowing fine dust having moisture to accumulate on the carrier by maximizing the area of contact with the air flow.

On the other hand, since it has a wrinkle structure, the humidity in the carrier is always high, so that the propagation of microorganisms such as bacteria can be facilitated. 5, the ceramic ball coated with silver iodide is immersed in the water contained in the water tank 140, so that the water sprayed from the water particle spraying unit 120 is sprayed to the fine dust and / It becomes possible to sterilize contaminated materials by bacteria or the like.

As a result, the air adsorbing fine dust having a high humidity is allowed to adhere to a large area or surface area while causing rotation and turbulence while passing through the carrier 131, thereby collecting the air adsorbed by the fine particles by the carrier 131 Can be made effective.

In another embodiment, the carrier 131 of the water particle collecting part 130 may be a porous ceramic ball coated with silver iodide. At this time, the water particles sprayed from the water particle spraying unit 120 can dissolve the silver iodide coated on the porous ceramic balls on the water particles that collect fine particles and / or contaminants such as bacteria. At this time, the silver iodide coated on the porous ceramic balls can be present as ions of iodine component and silver component in the water.

In this case, the iodine component of the silver iodide coated on the porous ceramic balls can coagulate the fine dust to increase the size thereof. Accordingly, the water particles adsorbed by the fine dust effectively aggregate the fine dust by the iodine component of the support 131, so that the support 131 can collect the fine dust effectively.

In addition, the silver component of silver iodide coated on the porous ceramic balls can sterilize various microorganisms generated in the carrier, thereby enhancing the quality of the fine dust-removed air. Accordingly, the water particles adsorbed by the fine dust effectively sterilize various microorganisms by the silver component of the carrier 131, and the carrier 131 sterilizes various microorganisms, thereby enhancing the quality of air from which the fine dust is removed. Further, by allowing the silver iodide to be coated on the porous ceramic balls, it is possible to use the one material to make the fine dust coagulate and sterilize various microorganisms.

The silver iodide coated on the porous ceramic ball is intended to perform the function of a coagulant and the function of a fungicide. The present invention is not limited to this and does not limit the use of various other materials.

On the other hand, the support 131 may have a structure in which the specific surface area per unit volume is maximized and turbulence is generated while rotating the air flow. As a result, the air adsorbing fine dust having a high humidity is removed while being deposited on a large surface area while being rotated and turbulent while passing through the carrier 131, thereby collecting the air adsorbed by the fine particles by the carrier 131 Can be made effective.

To this end, a rotating spiral structure is formed in the space in which the carriers 131 of the water particle collecting part 130 are received, and the carriers 131 can be received along the rotating spiral structure. As another embodiment, a structure such as a partition wall formed on the air inlet surface along a section perpendicular to the air flow may be formed with a rotating spiral structure so that the introduced air flows while drawing a rotating spiral. Also, a structure such as a partition wall formed on the air discharge surface along a cross section perpendicular to the air flow forms a rotating spiral structure so that the discharged air flows while drawing a rotating spiral.

In another embodiment, an additional air flow guide portion is disposed on the air inlet surface along a cross section perpendicular to the air flow on the water particle spraying portion 120 side in the water particle collecting portion 130 so that air adsorbed on the fine dust 131) while being rotated and turbulent, and can be removed while being deposited on a large surface area. As a result, the air adsorbing fine dust having a high humidity is removed while being deposited on a large surface area while being rotated and turbulent while passing through the carrier 131, thereby collecting the air adsorbed by the fine particles by the carrier 131 Can be made effective.

The water particle collecting part 130 is detachably coupled to the housing 101 and can be received so that the carrier 131 can be detached from the water particle turning part 130. [ That is, the water particle collecting unit 130 may be detachably coupled to the housing 101. In this case, the water particle collecting part 130 can be installed in the housing 101 in a structure in which the water particle collecting part 130 can be inserted into and / or detached from the housing 101. Therefore, fine dust accumulated in the carrier 131 can be rinsed off with water for a predetermined period of time, and the carrier 131 can be used again. That is, the water particle collecting unit 130 becomes reusable.

As another example, the carrier 131 can be accommodated so as to be detachable at the number of water particle turns 130. In this case, only the carrier 131 is discharged to the outside from the storage space of the number of water particle turns 130.
