A plurality of the washing water outlets 22 are formed on the lower surface of the washing water distribution tank 20 to distribute and discharge the washing water stored therein downward. Referring to FIG. 2 , the washing water outlets 22 are formed to form a plurality of rows and columns. The washing water outlets 22 are formed such that m are arranged in the front-back direction (y) and n are arranged in the left-right direction (x) to form an m*n matrix.

The washing water discharge port 22 includes a first discharge port 22a concavely formed on the lower surface of the washing water distribution tank 20 and formed in a bowl shape to contain a predetermined amount of washing water, and the first discharge port 22a. The lower surface of (22a) includes a second outlet (22b) formed in a slit shape to discharge washing water. At least a portion of the first discharge port 22a is formed such that its cross-sectional area decreases as it moves downward. A valve unit may be provided in the washing water outlet 22 to open and close.

The washing water falling unit 30 is installed below the washing water distribution tank 20 inside the casing 10 .

The washing water falling unit 30 includes a plurality of water wheel type water wheels 40 .

The waterwheel type water turbine 40 is a roll having a long length in the longitudinal direction y, which is the column direction, to correspond to the washing water outlets 22 disposed in the same row among the plurality of washing water outlets 22. , that is, formed in a cylindrical shape. In addition, a plurality of the waterwheel-type water turbines 40 are arranged in the left-right direction (x) so as to correspond to the washing water outlets 22 arranged in the same row among the plurality of washing water outlets 22. are spaced apart. Here, the left-right direction (x) is the flow direction (x) of the air. In the present embodiment, since n number of the washing water outlets 22 are formed in the left-right direction (x) as an example, the water wheel type water wheel 40 is arranged in the left-right direction (x). As an example, it will be described that n are disposed in the left-right direction (x) so as to correspond to the washing water outlets 22, respectively. As n number of the waterwheel waterwheels 40 are arranged in the left and right direction (x), which is the flow direction of the air, the air is washed a plurality of times by the washing water falling from the plurality of waterwheel waterwheels 40. . That is, since the air sequentially passes through n streams of washing water each falling from n waterwheel waterwheels 40, it can be washed n times.

Referring to FIGS. 3 and 4, the waterwheel type water turbine 40 includes a cylindrical portion 41 formed long in the longitudinal direction y, that is, in the longitudinal direction y, and the center of the cylindrical portion 41. A rotational shaft 42 provided on and rotating the cylindrical portion 41, an annular groove 43 formed on the outer circumferential surface of the cylindrical portion 41, and a drip tray groove 44 formed on the outer circumferential surface of the cylindrical portion 41 include

The rotating shaft 42 may support the waterwheel water wheel 40 to rotate by the weight of the washing water stored in the water receiving groove 44, and is connected to a separate motor (not shown) to It is also possible, of course, to rotate by driving (not shown). That is, the rotating shaft 42 may be rotated without power or may be driven by a motor (not shown). In this embodiment, the water wheel type water wheel 40 will be described as rotating without external power as an example.

The annular groove 43 is a groove formed in a ring shape along the circumferential direction on the outer circumferential surface of the cylindrical portion 41 . A plurality of the annular grooves 43 are formed spaced apart from each other at a predetermined interval along the longitudinal direction y. The number of the annular grooves 43 corresponds to the number of the washing water outlets 22 in the column direction y. The annular groove 43 serves to prevent the washing water discharged from the washing water outlet 22 from hitting the waterwheel water wheel 40 and splashing, and to guide the washing water to the drip tray groove 44 .

The drip tray groove 44 is a water bag formed in the annular groove 43 to temporarily accommodate washing water. A plurality of the drip tray grooves 44 are formed for each of the annular grooves 43 . A plurality of the drip tray grooves 44 are formed spaced apart from each other at a predetermined interval along the circumferential direction in the annular groove 43 . The drip tray groove 44 is deeper than the annular groove 43 and has a larger cross-sectional area. The drip tray groove 44 is formed long in a direction inclined at a predetermined angle θ from the radial direction of the water wheel water wheel 40, and temporarily supplies washing water according to the rotation of the water wheel water wheel 40. After receiving it, it can be discharged downward.

The drip tray groove 44 is formed long in a direction inclined in the direction of rotation of the waterwheel waterwheel 40, and the bottom surface is formed round in a hemispherical shape. As the droplet size and weight of the washing water falling from the drip tray groove 44 increase, the falling speed of the washing water increases and scattering can be minimized. Since the droplet size and weight of the falling washing water are proportional to the volume of the drip tray groove 44, it is preferable to design the volume of the drip tray groove 44 according to the droplet size of the washing water. In addition, it is preferable to design the volume of the drip tray groove 44 so that the falling speed of washing water is greater than the flow speed of air.

Referring to FIG. 4, among the waterwheel-type waterwheels 40, water tray grooves 411 and 412 formed in different annular grooves 43a and 43b in the same waterwheel have a first set distance d1 in the circumferential direction. It is formed at a position offset by For example, the first water receiving groove 411 formed in the first annular groove 43a formed in any one of the waterwheel-type water wheels 40 is the other second annular groove 43b. It is formed at a position offset by a first set distance (d1) in the circumferential direction from the second drip tray groove 412 formed in the. Therefore, the washing water droplets falling from the first water receiving groove 411 and the second water receiving groove 412 formed in different annular grooves in the same aberration fall to different positions with a predetermined first time difference, The washing water can fall more densely in time and space.

In addition, among the water wheel-type water wheels 40, the water receiving grooves 44 formed in the same annular groove in the same water wheel are formed at positions offset from each other by a third set distance d3 in the circumferential direction. Therefore, the water droplets falling from the plurality of drip tray grooves 44 formed in the same annular groove in the same aberration may fall to the same position as each other, but may fall with a second time difference due to rotation.

For example, when the rotational speed of the waterwheel waterwheel 60 is 60 rpm, the second time difference between the water droplets falling from each of the plurality of drip tray grooves 44 formed in the same annular groove ranges from about 0.13 seconds to about 0.19 seconds. The first time difference between the water droplets falling from the first drip tray groove 411 and the second drip tray groove 412 is within a range of about 0.05 to 0.12 seconds. Therefore, the washing water can fall more densely in time and space.

In addition, among the water wheel-type water wheels 40, the grooves of the drip trays formed on the water wheels 410 and 420 that are adjacent to each other but are different from each other are formed at positions offset by a second set distance d2 in the longitudinal direction y . For example, the first water receiving groove 411 formed in the first row of any first water wheel 410 among the waterwheel water wheels 40 is formed in the first row of the other second water wheel 420. It is formed at a position offset from the third gutter groove 421 by a second set distance d2 in the longitudinal direction y. Therefore, since the drops of washing water falling from the first drip tray groove 411 and the third drip tray groove 421 fall to different positions, the washing water discharged downward from the plurality of drip tray grooves falls more densely. can

In addition, the washing water dropping unit further includes an aberration linkage means for connecting and simultaneously rotating the plurality of waterwheel-type waterwheels 40 .

The water wheel interlocking means is described as an example as being a gear part 31e provided on each outer circumferential surface of the water wheel water wheels 40 and interlocking the water wheel water wheels 40 adjacent to each other by gear coupling. do.

The gear portion 31e may be formed on at least a portion of the outer circumferential surface of the cylindrical portion 31a, and in this embodiment, it is described as being formed on the front side and the rear side of the cylindrical portion 31a as an example. do.

The air washing unit 50 is provided below the washing water dropping unit 40 and is a unit for cleaning the air with washing water in the form of droplets falling from the washing water dropping unit 40 . The air cleaning unit 50 is coupled in communication with the lower portion of the casing 10, the upper and lower surfaces are formed to be open, the left side has an air inlet 50a through which air is introduced, and the right side has an air inlet 50a through which air is introduced. An exhaust air outlet 50b is formed. Therefore, the air cleaning unit 50 forms an air flow path in the left and right direction (x) from the air inlet 50a toward the air outlet 50b, so that the washing water falling from the washing water falling unit 40 and air come into contact to form a space for cleaning the air. A side surface of the air cleaning unit 50 may be formed of a perforated plate.

A blowing unit (not shown) for blowing air may be mounted in at least one of the air inlet 50a and the air outlet 50b.

The contaminated water tank 60 is provided in communication with the open lower part of the air cleaning unit 50, and is a tank in which the contaminated water discharged from the air cleaning unit 50 is received.

A contaminated water filter 70 for filtering the contaminated water is installed on the upper side of the contaminated water tank 60 .

The contaminated water tank 60 may include a contaminated water pump (not shown) for pumping and discharging the contaminated water. The contaminated water stored in the contaminated water tank 60 may be used as cleaning water or may be filtered and reused as the cleaning water.

The operation of the air cleaning system using the washing water drops according to an embodiment of the present invention configured as described above will be described as follows.

Referring to FIG. 1 , washing water for cleaning air is accommodated in the washing water distribution tank 10 .

The washing water accommodated in the washing water distribution tank 10 is downwardly discharged to the plurality of water wheel type water wheels 40 through the washing water discharge port 22 .

Referring to FIG. 3 , the washing water discharged through the washing water outlet 22 flows into the water receiving groove 44 located at the uppermost side among the plurality of water receiving grooves 44 formed in the water wheel 40 . At this time, the washing water flows into the drip tray groove 44 through the annular groove 43 of the water wheel 40 . The annular groove 43 serves to guide the washing water discharged from the washing water outlet 22 to flow into the drip tray groove 44 .

When a predetermined amount of washing water is filled in the drip tray groove 44, the water wheel 40 is rotated by the weight of the water contained in the drip tray groove 44.

When the drip tray groove 44 filled with washing water is moved downward to a certain position by the rotation of the water wheel 40, the washing water in the drip tray groove 44 flows downward. At this time, the washing water flowing down from the drip tray groove 44 falls while forming a droplet shape. That is, in the present invention, after the washing water is filled in the drip tray groove 44, it is dropped from the drip tray groove 44 so that it falls in the form of a drop.

The waterwheel-type water turbines 40 are connected to the gear unit 45 and drop washing water droplets while rotating at the same speed, so that the air and the surface of the washing water come into contact to clean the air.

The plurality of water wheel water wheels 40 are arranged in the left and right direction (x), which is the flow direction of the air, so that the air is washed multiple times by the washing water falling from the plurality of water wheel water wheels 40. . That is, the air is cleaned n times while sequentially passing through the n types of washing water streams each falling from the n waterwheel type water wheels 40, which has the advantage of high cleaning efficiency.

At this time, since the size, weight, and falling speed of the washing water droplets vary according to the volume of the drip tray grooves 44, the size, weight, and falling speed of the washing water droplets can maximize the cleaning efficiency of the air. The volume of the grooves 44 is set. Thus, the cleaning efficiency of air can be maximized.

As in the present invention, when the washing water is dropped in the form of drops, the air cleaning efficiency can be improved because the contact area with air is larger than when the washing water is sprayed in the form of mist using a nozzle or the like. In addition, in the case of the mist type, a phenomenon such as blowing by the wind generated during air movement occurs, but the effect of the blowing force or the like can be minimized for the washing water in the form of drops.

In addition, referring to FIG. 4, a plurality of annular grooves 43 formed on any one of the waterwheel type water wheels 40 are formed at positions offset from each other by the first set distance d1 in the circumferential direction. . As the annular grooves 43 are spaced apart, the drip tray grooves 44 are also formed to be spaced apart. That is, the first water receiving groove 411 formed in the first annular groove 43a has a first set distance d1 in the circumferential direction from the second water receiving groove 412 formed in the second annular groove 43b. It is formed at a position offset by Therefore, the washing water droplets falling from the first water receiving groove 411 and the second water receiving groove 412 formed in different annular grooves in the same aberration fall to different positions with a first predetermined time difference. Therefore, the washing water can fall more densely in time and space. The first time difference is about 0.08 seconds.

In addition, referring to FIG. 4 , a plurality of drip tray grooves 44 are spaced apart from each other by the third set distance d3 in the same annular groove 43 for each waterwheel waterwheel 40 . Therefore, the washing water droplets falling from the drip tray grooves 44 of the same annular groove 43 all fall to the same position, but fall with the second time difference due to the rotation of the water wheel. The second time difference is about 0.16 seconds.

In addition, referring to FIG. 4 , among the waterwheel waterwheels 40, the water tray grooves formed in adjacent but different waterwheels 410 and 420 are separated by a second set distance d2 in the longitudinal direction y. It is formed at an offset position. That is, the first water receiving groove 411 and the third water receiving groove 421 are formed at positions offset from each other by a second set distance d2 in the longitudinal direction y. Accordingly, the washing water droplets falling from the first water receiving groove 411 and the third water receiving groove 421 fall to different positions.

As described above, the annular grooves 43 and the drip tray grooves 44 according to the embodiment of the present invention are arranged in a zigzag manner at different positions, so that the washing water drops discharged downward from the plurality of drip tray grooves reduce the time difference. It can be left and dropped more densely.

In addition, since the plurality of waterwheel-type water wheels 40 are arranged along the flow direction of the air, high cleaning efficiency is ensured while the air passes through the air cleaning unit 50 as the washing water falls very densely. It can be.

In addition, the plurality of waterwheel waterwheels 40 are coupled to be engaged with each other through the gear unit 45, so that they rotate at the same speed as each other. Therefore, since the rotational speed of the plurality of waterwheel waterwheels 40 is the same, the size and weight of the falling washing water droplets can be uniformly maintained within a predetermined range.

The washing water falling after washing the air in the air washing unit 50 passes through the contaminated water filter 70 in a downward direction.

While passing through the contaminated water filter 70, foreign substances such as dust included in the washing water are filtered.

Washing water that has passed through the contaminated water filter 70 and has fallen downward is collected in the contaminated water tank 60 .

The washing water collected in the contaminated water tank 60 is pumped by a pump and circulated to the washing water distribution tank 10 to be reused.

As described above, in the present invention, cleaning efficiency of the air can be further improved by cleaning the air by dropping the cleaning water in the form of droplets through the waterwheel water wheels 40 .

In addition, by optimizing the shape and arrangement of the annular grooves 43 and the water receiving grooves 44 of the waterwheel water wheels 40, the washing water can fall very densely, so that the contact between air and washing water can be maximized. there is.

A plurality of the conveying rollers 231 are disposed spaced apart from each other by predetermined intervals in the front-back and left-right directions, and the conveying direction of the dehumidifying sheet 220 is changed multiple times by the conveying rollers 231 . Accordingly, the surface area of the dehumidifying sheet 220 supported by the conveying rollers 231 is maximized, and drying efficiency by a heater described later may be increased. The conveying rollers 231 may be driven by a separate motor (not shown) or the like.

The sheet recycling unit 240 is a drying device installed on at least one of upper and lower portions of the dehumidifying chamber 210 to dry and regenerate the dehumidifying sheet 220 .
