In addition, the filter structure 10 for collecting fine particles may further include a collecting friction layer 13 . The filter structure 10 for collecting fine particles may be formed by coupling the collecting cilia 12 to one surface of the band-shaped or plate-shaped cilia support 11 . The filter structure 10 for collecting fine particles may form a basic configuration of a filter for collecting fine particles. The filter structure 10 for collecting fine particles may have a width or length determined according to the shape of the filter for collecting fine particles.

The ciliary support 11 may be formed in a band shape having a predetermined width and length. In addition, the ciliary support 11 may be formed in a plate shape having a predetermined width and length. The ciliary support 11 may be formed by woven fibers. In addition, the ciliary support 11 may be formed of a resin film. The ciliary support 11 may be rubbed with the collecting cilia 12 to form a (+) charge or a (-) charge, or may be charged with a (+) polarity or (-) polarity. In addition, the cilia support 11 may generate static electricity through friction with the collecting cilia 12 .

The cilia support 11 may be formed of a material that forms a (+) charge or a (-) charge through friction with the collecting cilia 12 located on one surface. In addition, the cilia support 11 may be formed of a material that is charged with (+) polarity or (-) polarity through friction with the collecting cilia 12 .

In addition, the cilia support 11 may be formed of a material such as a resin having a high tendency to be charged with a relatively negative (-) polarity compared to the collecting cilia 12 through friction with the collecting cilia 12 . For example, the ciliary support 11 may be formed of a resin such as Teflon, silicone resin, vinyl chloride resin, or polyethylene. In addition, the ciliary support 11 may be formed of a material such as a resin having a hydrophobic property with a tendency to be charged in a negative (-) polarity. When the ciliary support 11 is formed of a material having hydrophobic properties, the collected fine particles can be easily removed by water. In addition, the ciliary support 11 may be formed of a resin having a high tendency to be charged in a relatively (+) polarity compared to the collecting cilia 12 .

In addition, the collecting cilia 12 may be spaced apart from each other at predetermined intervals in the longitudinal direction and the width direction of the cilia support 11 . That is, the collecting cilia 12 may be positioned to form a lattice shape. The collecting cilia 12 may form an air passage through which air passes together with the cilia support 11 positioned above and below while being spaced apart from each other. The separation distance and height of the collecting cilia 12 may be the width of the air passage. The collecting cilia 12 can adjust the size of the air passage by the separation distance and height. In addition, the size and density of the air passage can be adjusted by the thickness of the collecting cilia 12 . Here, the density may mean the number of the collecting cilia 12 per unit area of the cilia support 11 . When the density is high, the collecting cilia 12 are formed relatively densely, so that the number of collecting cilia 12 per unit area is large, and the size of the air passage is formed small. Accordingly, the collecting cilia 12 may have a thickness, a separation distance, and a height according to the size of the air passage required by the filter.

In addition, the collecting cilia 12, as shown in FIG. 2, may extend in a straight shape and have an end bent in a straight or curved downward direction. The collecting cilia 12 may have an arc-shaped end and may cause friction while gently contacting the cilia support 11 or the collecting friction layer 13 . In addition, the collecting cilia 12 can more efficiently collect the fine particles by increasing the surface area where the fine particles can be collected around the area where friction occurs. In addition, as shown in FIGS. 3A and 3B , the collecting cilia 12 may be formed of fine fibers and entangled with each other on one surface of the cilia support 11 . In this case, the collecting cilia 12 may form a relatively fine air passage compared to the case where it is formed in a straight shape.

For example, the collecting cilia 12 may be formed of a resin such as polypropylene, polyurethane, acrylic resin, polyester or nylon. In addition, the collecting protrusion 120 may be formed of a material such as a resin having a hydrophobic property with a tendency to be charged with a (+) polarity. When the collecting protrusion 120 is formed of a material having hydrophobic properties, the collected fine particles may be easily removed by water. On the other hand, the collecting cilia 12 may be formed of a resin having a high tendency to be charged in a relatively negative (-) polarity compared to the cilia support 11 .

The collecting cilia 12 may be formed of a material having a different degree of being charged with the cilia support 11 by friction. The collecting cilia 12 may be formed of a material having a polarity opposite to that of the cilia support 11, preferably by friction. Accordingly, the collecting cilia 12 can increase the collecting efficiency of fine particles having more various degrees of polarity. On the other hand, the collecting cilia 12 may be formed of the same material as the cilia support 11 or a different material.

The collecting cilia 12 may be formed to a predetermined height. The height of the collecting cilia 12 affects the distance between the cilia support 11 and the size of the air passage through which the air passes when the filter is formed. Therefore, the height of the collecting cilia 12 may be determined in consideration of the flow rate of air required in the filter in which the filter structure 10 is used.

The collecting friction layer 13 may include a collecting resin layer 13a and collecting particles 13b. The collecting friction layer 13 may be formed by coating the other surface of the ciliary support 11 to a predetermined thickness.

In particular, the collecting friction layer 13 may have a curved surface formed by the collecting particles 13b. In addition, the collecting friction layer 13 may have a predetermined surface roughness. Accordingly, the trapping friction layer 13 may be curved or formed to have a surface roughness, so that it can be rubbed more efficiently with the trapping fibers.

The collecting resin layer 13a may be formed of a material that forms a (+) charge or a (-) charge through friction with the collecting cilia 12 .

The collecting resin layer 13a may be formed of a resin material that generates charges having a polarity opposite to that of the collecting cilia 12 . For example, the collection resin layer 13a may be formed of a resin such as Teflon, silicone resin, vinyl chloride resin, or polyethylene. The collecting resin layer 13a may be formed of the same material as the cilia support 11 . In addition, the collecting resin layer 13a may be formed of a different kind of resin material from the collecting cilia 12 .

The collecting resin layer 13a may be formed of a resin material that generates charges having a polarity opposite to that of the collecting cilia 12 .

In addition, the collection resin layer 13a may be formed of a material such as a resin having a hydrophobic property along with a tendency to be charged in a negative (-) polarity. When the collecting resin layer 13a is formed of a material having hydrophobic properties, the collected fine particles may be easily removed by water. On the other hand, the collecting resin layer 13a may be formed of a resin having a high tendency to be charged in a relatively (+) polarity compared to the collecting cilia 12 .

The collecting particles 13b may include ceramic particles such as zeolite, alumina, titanium dioxide, or zirconia. The collecting particles 13b are located dispersedly in an area including the surface of the collecting resin layer 13a. More specifically, the collecting particles 13b may be positioned so that a part is exposed to the surface of the collecting resin layer 13a and a part is submerged in the collecting resin layer 13a.

The collecting particles 13b may more efficiently collect contaminants of different sizes or types.

The collecting friction layer 13 is a dispersion formed by mixing 1 to 20% by weight of a resin material, 1 to 50% by weight of collecting particles, and 50 to 90% by weight of a solvent.

The filter structure 10 forming the filter 20 for collecting fine particles may be formed of the structure 10 of the filter 20 for collecting fine particles according to FIGS. 1A to 5B described above. In this case, the filter structure 10 may preferably be formed in a band shape having a length longer than a width. Meanwhile, in the filter structure 10 of FIGS. 9 and 10 , the collecting friction layer 13 is not specifically illustrated, but the collecting friction layer 13 may be coated on one surface and the other surface of the ciliary support 11 .

The filter 20 for collecting fine particles may be formed in a disk shape having a predetermined thickness and diameter as a whole while the filter structure 10 is wound in a roll shape. That is, the filter 20 for collecting fine particles may include a wound filter structure 20a. The wound filter structure 20a may be positioned so that the cilia support 11 adjacent to the inner and outer sides are spaced apart from each other, and the collecting cilia 12 therebetween extend from the inside to the outside. The collecting cilia 12 may rub against the cilia support 11 or the collecting friction layer 13 located on the outside. The thickness and diameter of the filter 20 for collecting fine particles may be determined according to the height of the collecting cilia 12 , the width of the cilia support 11 , and the number of windings. Accordingly, the filter 20 for collecting fine particles can be easily formed to have a thickness and an area required by the filtering system.

In addition, the filter 20 for collecting fine particles adjusts the winding tension or winding strength of the ciliary support 11 during the winding process of the filter structure 10 to adjust the separation distance between the ciliary support 11 and the collecting cilia 12 . The degree of deformation can be controlled. Thereby, in the filter 20 for collecting fine particles, the size of the air passage formed between the collecting cilia 12 between the cilia supports 11 can be adjusted. In addition, in the filter 20 for collecting fine particles, the size of the air passage may be adjusted according to the thickness and density of the collecting cilia 12 .

The filter 20 for collecting fine particles can control the air permeation flow rate, the collection efficiency of the fine particles, and the size of the fine particles to be collected by adjusting the thickness and the size of the air passage. For example, when the tension is strong in the winding process of the filter structure 10, the separation distance between the ciliary supports 11 is relatively small and the air passage is small, the flow rate of air passing through is reduced, while the fine particles The collection efficiency can be increased. In addition, in the filter 20 for collecting fine particles, the number of air passages per unit area is increased, so that the efficiency of collecting fine particles may be increased. Conversely, when the tension is weak during the winding process of the collecting structure, the separation distance between the ciliary supports 11 is relatively large, and the size of the air passage is increased to increase the flow rate of air, while the collecting efficiency of fine particles is reduced. can be In addition, the filter 20 for collecting fine particles may also collect substances such as NO _x , SO _x , and VOCs by the trapping friction layer 13 .

In addition, in the filter 20 for collecting fine particles, since the cilia support 11 and the collecting cilia 12 are formed of a hydrophobic resin material, after collecting the fine particles, it can be washed with water and used again. Accordingly, the filter 20 for collecting fine particles can reduce the maintenance cost of the filtering system.
