Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for purifying pollutants,

The present invention relates to a filter for purifying pollutants and a filter cartridge, and more particularly, to a filter for purifying pollutants and a filter cartridge including the filter, which are configured to very easily maintain a three-dimensional filter structure capable of effective purifying treatment.

There are various pollutants that emit pollutants. Pollutants are emitted from various industrial facilities such as chemical treatment facilities that discharge waste gas, power plants that generate power by consuming fuel, and power generating facilities that produce electricity. Contaminants released from pollutants are distributed in the air in the form of fine particles, which can cause various diseases including respiratory diseases.

Contaminants distributed in the air can be treated in various ways. Pollutants can be treated in a variety of ways, including using chemicals, using electrical power, or collecting contaminants using filters. Among them, the processing method using a filter is easy to apply and has high processing efficiency and is utilized in various fields. Korean Patent Publication No. 10-2013-0051058 discloses an example of such a filter.

The filter can be contacted with the gas so that contaminants contained in the gas can be directly filtered out of the vessel. Accordingly, the arrangement in which the filter can contact the gas more effectively may be important. In the conventional case, a filter having a plate-like sheet shape is disposed in a form crossing the flow path. If necessary, tension may be applied to the ends of the filter to move the filter in a manner to unwind or loosen the filter.

However, when the concentration of the pollutant is high or the amount of discharged gas is large, there is a problem that the filter is damaged due to a large pressure acting on the plate filter. In addition, since the contact area between the gas and the filter is also limited, the treatment efficiency is often inadequate. In order to improve this, there has been an attempt to change the shape or structure of the filter, but there has been a problem in that it is very difficult to maintain the structure or shape, such as the filter being deformed by the gas pressure.

Such contaminants may be, for example, one or more selected from dust, metal oxides, soot, heavy metals, sulfur oxides, or nitrogen oxides.

Hereinafter, the pollutant-purifying filter according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5. FIG.

FIG. 1 is a perspective view of a pollutant purifying filter according to an embodiment of the present invention, FIG. 2 is a front view of a part of the filter of FIG. 1, and FIG. 3 is a side view of the filter of FIG.

1 to 3, the filter 1 for purifying a pollutant according to an embodiment of the present invention includes a first support 200, a first support 200, a second support 200, A plurality of first corners 110 and a plurality of second corners 120 spaced apart from the first corners 110 and a plurality of second corners 120 spaced apart from the first corners 110 and the second corners 120, Shaped filter body 100 including a plurality of flat portions 130 connecting the first corner portion 110 and the second corner portion 120 in the filter body 100, And a second support 300 for maintaining the shape of the filter body 100 by providing a restoring force to the filter body 100. According to an embodiment of the present invention, the second support 300 may include an elastic wire 301 supporting the filter body 100.

The pollutant purifying filter 1 according to an embodiment of the present invention includes a filter body 100 having a three-dimensional shape that is continuously refracted as shown in FIG. The filter body 100 is supported by the first support body 200 and the second support body 300 that support different portions of the filter body 100, and can easily maintain its own shape. Particularly, the second support member 300 may be formed directly on the filter member 100 to come in close contact with the filter member 100, to impart elasticity to the filter member 100, to maintain a gap between the refracted portions, 100 are connected to each other so that the shape of the filter body 100 can be maintained very effectively so that the filter body 100 can be immediately restored to the corrugated plate shape have. For example, even when the pollutant-purifying filter 1 is wound on a shaft or the like and stored in the form of a cartridge, the restoring force provided by the first support 200 and the second support 200, The filter body 100 can be easily restored to the three-dimensional shape of the corrugated plate shape as soon as it is unwound from the shaft.

In addition, the filter 1 for purifying a pollutant according to an embodiment of the present invention can further enhance the effect of maintaining the shape of the filter body 100 by using the reinforcing member 400 formed in a line. That is, the filter body 100 is supported and maintained in shape through the first support body 200 connected to the edge of the filter body 100 and the second support body 300 formed on the filter body 100 itself, By using the reinforcing member 400 formed in a complementary manner, the deformation of the entire pollutant-purifying filter 1 can be minimized and the purifying operation can be performed in a stable state.

As shown in FIGS. 1 to 3, the filter body 100 may be formed in a three-dimensional shape that is repeatedly refracted along a plurality of corner portions. The filter body 100 includes a plurality of first corners 110, a plurality of second corners 120 spaced apart from the first corners 110, and a plurality of first corners 110, And a plurality of planar parts 130 connecting the first corner part 110 and the second corner part 120 between the corner parts 120. That is, as shown in FIGS. 1 to 3, the flat portion 130 is connected between the first corner portion 110 positioned upward and the second corner portion 120 positioned downward opposite to the first corner portion 110 So that the filter body 100 can be formed. Since the filter body 100 having such a shape accommodates a plurality of flat portions 130 within a certain volume, the surface area per unit volume or the contact area per unit volume can be greatly increased.

Thus, the filter body 100 can contact with more gas in a confined space inside the flow path through which the pollutant-containing gas, etc. flows. As a result, the treatment effect of the pollutant can be greatly improved. Also, since the filter element 100 is repeatedly refracted along the first corner 110 and the second corner 120, the tension applied to the filter element 100 through the refracted portion can be easily solved. That is, even when the back pressure of the gas is strong, the first corner part 110 or the second corner part 120 flows in a manner such that the buffer part 100 can be buffered, Can be prevented. As described above, it is possible to perform a more stable and effective purifying operation by using the filter body 100 having a three-dimensional shape.

The filter body 100 may be made of, for example, a fibrous material or a porous material, and may be manufactured from various materials including one or more natural substances or compounds. The filter body 100 can be processed into various forms such as a filter or a nonwoven fabric. The filter body 100 may be formed by folding and pressing the processed material into a sheet, or by three-dimensionally molding the material in a repeatedly bent plate shape. In addition, the filter body 100 having a three-dimensional shape can be formed by various methods.

The first support 200 may be linear, network or sheet-like. The sheet phase may be a porous sheet phase. The first support 200 may include a refractable wire or a refractable mesh network. The first support 200 may be formed of various materials such as fibers, plastics, or metals, and may be formed entirely of a single material or may be formed of a combination of one or more materials. The first support body 200 may have a core member or the like inserted therein to maintain strength or shape. The first support 200 may be coated with a coating material on the outside to reinforce elasticity and prevent contamination. The first support 200 capable of being refracted can be formed in various various ways.

In other words, the first support 200 having a mesh shape is used as a reference in the present specification, but the present invention is not limited thereto. The first support 200 may be formed in various shapes using a refractable linear or sheet-like material. The first support body 200 is connected to the first corner 110 of the filter body 100. 1 to 3, the filter body 100 may include a first edge portion 110 and a second edge portion 110, as described above, May be formed in a shape that is repeatedly refracted along the first direction 120. The plurality of first corner portions 110 formed repeatedly in the filter member 100 may be connected to the first support member 200 to maintain a gap therebetween.

The first corner 110 may be directly connected to the first support 200 or may be connected via the reinforcing member 400 when the reinforcing member 400 is formed. That is, the reinforcing member 400 is fixed to one side (which may be the first corner portion) of the filter body 100 and the first support body 200 is attached to the reinforcing member 400, The corner portion 110 can be connected to the first support 200 by the reinforcing member 400. [ For example, the reinforcing member 400 may be passed through the filter body 100 in various ways, such as by passing the reinforcing member 400 through one side of the filter body 100, by sewing it in close contact with the filter body 100, by bonding it with an adhesive, And the first supporting body 200 may be connected to the fixed reinforcing member 400. [ The first support 200 may also be secured to the reinforcement member 400 in various manners, such as being pierced through at least a portion of the reinforcement member 400, sewn, glued, bonded by heat or pressure, and the like.

However, when the reinforcing member 400 is disposed apart from the first support 200, the reinforcement member 400 and the first support 200 may be connected to each other using a separate connector, The overall supporting force can be enhanced. Also, the reinforcing member 400 can be connected to the second support 300 in the same manner as the method of connecting to the first support 300, and the support force of the filter as a whole can be enhanced more effectively.

In this way, the first corner 110, the first support 200, the reinforcement member 400, and the like can be connected very firmly. When the reinforcing member 400 includes the first reinforcing wire 410 and the second reinforcing wire 420, the first corner portion 110 is connected to the first supporting member 200 via the first reinforcing wire 410, Lt; / RTI > The reinforcing member 400 will be described later in more detail.

On the other hand, the second support body 300 can be formed on the filter body 100 to effectively maintain the shape of the filter body 100. The second support body 300 may include an elastic wire 301 for supporting the filter body 100. The elastic wire 301 may be formed on one side of the filter body 100 or on both sides of the filter body 100 as shown in Figs. In the present specification, description will be made on the basis of the case where the elastic wire 301 is formed on one surface of the filter member 100. [ The elastic wire 301 may adhere to the surface of the filter body 100 to elastically support the filter body 100, thereby easily maintaining the shape of the filter body 100. The elastic wires 301 may constitute, for example, a net in which at least a part of the filter body 100 is exposed therebetween so as to intersect with each other.

The elastic wire 301 may be formed of various materials having elasticity. For example, the elastic wire 301 which is brought into close contact with the surface of the filter body 100 with a material having elasticity, such as metal or plastic, and refracted in a shape corresponding to the shape of the filter body 100 can be formed. 1 to 3, the elastic wire 301 supports the filter body 100 by wrapping the surface of the filter body 100 and applies elasticity to the filter body 100 to adjust the shape of the filter body 100 . The elastic wire 301 may be formed at one side thereof facing the filter body 100 with a contact surface (refer to 301b in Fig. 2) parallel to the filter body 100, and may be processed into a flat bar shape for this purpose. That is, the contact surface 301b may be one surface parallel to the filter body 100 located on the side of the flat bar-shaped elastic wire 301. [ The elastic wire 301 includes a surface parallel to the filter body 100, such as the contact surface 301b, so that the elastic body 301 can more easily support the filter body 100. [ However, the present invention is not limited to this, and the second support 300 can be formed of elastic wires 301 having various shapes.

The elastic wire 301 may include a refracting portion 301a which is elastically refracted along at least one of the first corner portion 110 and the second corner portion 120. [ That is, as shown in FIGS. 2, 3, 4, and so on, the first and second corner portions 110 and 120 are provided with a plurality of refracting portions 301a and 302b that are elastically refracted in such a manner as to surround the outside or inside of at least one of the first corner portion 110 and the second corner portion 120, May be formed on the elastic wire 301. When the refracting portion 301a is formed as described above, the shape of the first corner portion 110 or the second corner portion 120 can be easily maintained particularly by the elasticity of the refracting portion 301a. This will be described in more detail below.

The reinforcing member 400 may be formed in such a manner that it is fixed to one side of the filter body 100. The reinforcing member 400 may be formed in a line as described above. The reinforcing member 400 is connected between at least one of the plurality of first corner portions 110, between the plurality of second corner portions 120 and between the plurality of plane portions 130, ). &Lt; / RTI > For example, the reinforcing member 400 and the reinforcing member 400 may be formed in such a manner as to penetrate between the first corner portions 110, penetrate between the second corner portions 120, The filter body 100 can be easily connected to each other and can be firmly fixed in the above-described manner. The reinforcing member 400 includes a first reinforcing wire 410 connected between the plurality of first corners 110 and a second reinforcing wire 420 connected between the plurality of second corners 120 .

In this specification, the first reinforcing wire 410 and the second reinforcing wire 420 are formed. However, if necessary, the third reinforcing wire 410 extending through the plurality of flat portions 130 Not shown) may be formed. The shape of the filter body 100 can be more easily maintained by using the reinforcing member 400 connected to the filter body 100 at different positions and supporting the filter body 100. [ The reinforcing member 400 may be made of a material capable of being refracted, or may be made of a material having an elastic force. Particularly, a first reinforcing wire 410 is formed at a position in contact with the first corner portion 110 and the first supporting member 200 is fixed to the first reinforcing wire 410, 200 can be connected to the first corner portion 110 by the reinforcing member 400. In this manner, a very rigid support structure can be formed stepwise on one side of the filter member 100. [

The first reinforcing wire 410 is connected to the plurality of first corner portions 110 and the second reinforcing wire 420 is connected to the plurality of second corner portions 120 located on the opposite side of the first corner portion 110, do. The portions of the first reinforcing wire 410 and the second reinforcing wire 420 connected to the respective corners can be easily fixed in the manner as described above. Accordingly, the first corner portion 110 and the second corner portion 120 can be maintained at respective intervals by the reinforcing member 400, and the shape change can be minimized. When the reinforcing member 400 such as the first reinforcing wire 410 and the second reinforcing wire 420 and the first supporting member 200 have an elastic force, the gap between the plurality of first corner portions 110, The spacing between the two second corner portions 120 may be somewhat resilient.

Hereinafter, an operation process and a use process of the pollutant purifying filter according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 to 5. FIG.

Fig. 4 is an operation diagram showing a part of the filter of Fig. 1, and Fig. 5 is a state of use showing an example of use of the filter of Fig.

The pollutant purifying filter 1 according to an embodiment of the present invention can maintain its shape while being highly elastically deformed as shown in FIG. In particular, since the second support 300 includes the elastic wire 301 held in close contact with the filter member 100, it can be easily restored to its original shape due to the elasticity of the elastic wire 301. The refracting portion 301a of the elastic wire 301 allows the shape of each corner portion to be elastically deformable, but can be restricted so as not to be deformed beyond the elastic limit. The portion of the elastic wire 301 that is in close contact with the flat surface portion 130 can also be elastically supported by the flat surface portion 130 in close contact with the filter body 100 so as to maintain a flat surface without being refracted. This makes it possible to cope with the situation where the filter body 100 is deformed due to the pressure applied to the filter body 100 such as the back pressure rises and to keep the filter body 100 in its original three-dimensional shape have.

The pollutant-purifying filter 1 can be used in a flow path in which a gas (A) containing a pollutant flows, as shown in Fig. 5, arranged in a direction crossing the flow direction of the gas. At this time, even if the gas A containing the pollutant contacts the pollutant purifying filter 1 and pressurizes, the first support 200, the second support 300, the reinforcing member 400, etc. The shape change can be minimized by the complex supporting action of the filter body 100, and the filter body 100 can be maintained in a three-dimensional shape. Therefore, it is possible to purify contaminants more effectively by increasing the contact area between the filter A 100 and the gas A containing the contaminant. The purified gas A 'that has passed through the pollutant-purifying filter 1 proceeds in the flow direction and can be discharged to the outside through an outlet (not shown) or the like.

On the other hand, the pollutant-purifying filter 1 may be formed so as to move within the flow path of the gas under the attraction force. For example, as shown in Fig. 5, the pollutant-purifying filter 1 is moved in a direction parallel to the extending direction of the pollutant-purifying filter 1 (see a dotted line in Fig. 5) can do. In this case, the attracting force (which may be provided from a driving unit such as a motor) acting in the moving direction of the pollutant purifying filter 1 may generate a tension that causes deformation of the filter, but the first supporting member 200, 2 can also be easily solved by the supporting action of the supporting member 300, the reinforcing member 400 and the like. That is, even if the attracting force for pulling and moving the filter is applied, the attracting force is directly transmitted to the first supporting member 200 and the reinforcing member 400, and the transmission to the filter body 100 itself can be minimized. Further, even when tension is applied to some filter elements 100, the elastic wire 301 of the second support body 300 can be easily supported and resiliently supported, so that the shape of the filter element 100 can be easily Can be maintained.

In this way, the pollutant-purifying filter 1 can stably maintain the three-dimensional shape, and thereby it is possible to treat the pollutants contained in the gas very effectively.

Hereinafter, the pollutant purifying filter according to another embodiment of the present invention will be described in detail with reference to FIGS. 6 to 9. FIG. For simplicity and clarity of explanation, portions different from those of the above-described embodiments will be mainly described, and description of other components not described separately will be omitted from the description given above.

FIG. 6 is a perspective view of a pollutant purifying filter according to another embodiment of the present invention, and FIG. 7 is a front view showing a part of the filter of FIG. 6 in an enlarged manner. Fig. 8 is a view showing a modification of the second support of the filter of Fig. 6, and Fig. 9 is a state of use showing the use of the filter of Fig.

Referring to FIGS. 6 and 7, the pollutant purification filter 1-1 according to another embodiment of the present invention may include a second support 300-1 including a gap retaining member 302. FIG. That is, the pollutant purification filter 1-1 according to another embodiment of the present invention is connected to the first support 200, the first support 200, which is refractable and formed in a linear, A plurality of second corners 120 spaced apart from the first corners 110 and positioned opposite the first corners 110 and a plurality of first corners 110 extending from the first corners 110, Shaped filter body 100 including a plurality of flat portions 130 connecting the first corner portion 110 and the second corner portion 120 between the first corner portion 120 and the second corner portion 120, And a second support body 300-1 which is formed on the filter body 100 and provides a restoring force to the filter body 100 to maintain the shape of the filter body 100. [ The second support 300-1 may be formed in such a manner that it includes a gap retaining member 302 interposed between adjacent planar portions 130 of the filter body 100. [

The pollutant-purifying filter of the present invention may be formed such that the second support member includes the above-described elastic wire (see 301 in Figs. 1 to 5), may include the gap retaining member 302, And may include both the elastic wire 301 and the gap holding member 302. Therefore, the embodiment for explaining the pollutant-purifying filter of the present invention is different from the one embodiment only for the sake of convenience of description, and one does not exclude the other. The second support body includes an elastic wire 301 for supporting the filter body 100, a gap retaining member 302 interposed between adjacent planar portions 130 of the filter body 100, (Not shown) connecting at least two points that are different from each other and not connected to the support.

The connecting member can be formed in such a manner that, for example, a wire member on the line that is able to be bent is connected between the adjacent flat portions 130 of the filter body 100, between the adjacent second corner portions 120, and the like. The wire member may pass through a plurality of flat portions 130 or may be connected to a plurality of second corner portions 120 to support the filter member 100. The connecting member may be passed through one side of the filter body 100 or may be fixed to the filter body 100 in various ways such as by tightly adhering to the filter body 100, sewing it, bonding it with an adhesive, bonding it by applying heat or pressure .

For example, when the second support body is formed of the connecting member, the first support body is connected between the plurality of first corner portions 110, and the second support body is connected between the plurality of second corner portions 120 So that different corner portions of the filter body 100 are supported by using the first and second supports with the plane portion 130 interposed therebetween. Accordingly, it is possible to provide a restoring force for relieving the deformation of the filter body 100 and to easily maintain the corrugated plate shape. As described above, it is possible to fix the line-shaped reinforcing member 400 to one side of the filter member 100 to compensate the strength while maintaining the shape of the filter member 100. One or more of the reinforcing members 400 may be formed at different positions of the filter body 100. For example, as described above, a reinforcing member 400 (not shown) is provided between at least one of the plurality of first corner portions 110, between the plurality of second corner portions 120, and between the plurality of plane portions 130, So that the filter body 100 is supported and the strength of the filter body 100 is compensated.

The gap holding member 302 may be interposed between the planar portions 130 of the filter body 100 as shown in Figs. A plurality of spacing members 302 may be formed between a plurality of adjacent planar portions 130. The gap retaining member 302 may comprise an elastic material so that at least a portion of the retaining member 302 may be resiliently deformed to maintain the spacing or configuration between the planar portions 130. [ The gap holding member 302 may be made of silicon or a natural or synthetic rubber material and attached to the filter body 100. However, the present invention is not limited thereto, and it is possible to form the gap retaining member 302 in various forms that are interposed between the flat portions 130 and elastically restored and can maintain a circular shape. For example, it is also possible to form the gap retaining member 302 in such a manner that metal or plastic having elasticity is appropriately processed and inserted between the planar portions 130, or the like.

At least a portion of the gap retaining member 302 may be formed in a wedge shape that decreases in width toward the first corner portion 110 or the second corner portion 120 as shown in Figs. In other words, the gap retaining member 302 is interposed between the planar portions 130 and is located on the side adjacent to the first corner portion 110 or the second corner portion 120 so that at least a portion of the first corner portion 110 or And may be formed in a wedge shape that gradually decreases in width corresponding to the shapes of the first corner portion 110 and the second corner portion 120. [ At least a portion of the gap retaining member 302 may be in contact with the first corner portion 110 or the second corner portion 120 between the adjacent planar portions 130.

That is, the gap holding member 302 extends from the flat surface portion 130 located on both sides of the first corner portion 110 of the filter body 100 to the first corner portion 110 where the flat surface portion 130 is gathered The filter member 100 may be interposed between the planar portion 130 and the first corner portion 110 and may extend from the planar portion 130 located on both sides of the second corner portion 120 of the filter member 100, To the second corner portion 120 where the first and second corner portions 130 and 130 are gathered, and is interposed inside the refraction portion including the plane portion 130 and the second corner portion 120. Accordingly, the gap holding member 302 can be formed in such a manner that each corner portion and the flat surface portion 130 can be very easily supported so that the bending portion of the filter body 100 is not deformed.

However, the arrangement and shape of the gap retaining member 302 do not need to be limited as described above. At least a portion of the gap retaining member 302 may extend between adjacent first edge portions 110 or between adjacent second edge portions 120 to define first edge portions 110 and Or may be deformed to abut both the second corner portions 120 adjacent to each other. For example, as shown in FIG. 8 (a), at least a portion of the gap retaining member 302 may extend between adjacent second corner portions 120 and may include a second edge portion 120 adjacent to the second corner portion 120, And it is possible to form the second support 300-1 including the gap keeping member 302. [ (Fig. 8 (a) is a front view of a filter showing a modification of the gap holding member, and Fig. 8 (b) is a side view thereof)

The gap holding member 302 is interposed between the flat portions 130 to minimize a change in spacing between the flat portions 130 and thus to more effectively restrict the movement of the corner portions located between the flat portions 130. [ In addition, as described above, the interval holding member 302 is in contact with all the adjacent edge portions, and the variation in the interval between the edge portions can be minimized. As shown in FIG. 8 (a), when the interval between the planar portions 130 is relatively narrow, it is easy to form the gap retaining member 302 so as to be in contact with the adjacent corner portions. In addition, the shape of the filter body 100 can be easily maintained by forming the gap holding member 302 between the planar portions 130 in various manners.

On the other hand, the gap holding member 302 may be formed only in a portion along the width direction (the transverse direction in FIG. 8 (b)) of the filter body 100 as shown in FIG. 8 (b) By such a configuration, it is possible to minimize variations in the distance between the adjacent corners so that the shape of the filter body 100 is maintained, but the flow of the gas passing through the filter body 100 is not disturbed. That is, one or more gap holding members 302 are separated from each other in the width direction of the filter body 100 so that gas can easily pass through the gap holding members 302 and come into contact with the filter body 100, As shown in FIG. The positions where the gap holding members 302 are formed are illustrative and it is possible to form the second supports 300-1 by dispersing the gap holding members 302 at various other positions as necessary.

The pollutant purifying filter 1-1 according to another embodiment of the present invention may also be used in the same manner as the above-described method. The pollutant-purifying filter 1-1 may be arranged in a flow path through which a gas (A) containing a pollutant flows, as shown in Fig. 9, in a direction crossing the flow direction of the gas. As described above, the pollutant purifying filter 1-1 minimizes the shape change by the combined supporting action of the first supporting body 200, the second supporting body 300-1, the reinforcing member 400, It is possible to maintain the filter 100 in a three-dimensional shape, thereby increasing the contact area between the gas A containing the pollutant and the filter 100, thereby purifying the pollutant more effectively.

Particularly, by using the second support 300-1 including the gap holding member 302, it is possible to minimize the change in the distance between the adjacent planar portions 130 and to reduce the shape of the filter body 100 in three dimensions . Therefore, even if the gas A containing the pollutant contacts with the pollutant purifying filter 1-1 and pressurizes the pollutant, the pollutant can be purified while stably maintaining the shape. The purified gas A 'passing through the pollutant purifying filter 1-1 may flow in the flow direction and be discharged to the outside through an outlet (not shown) or the like.

In addition, even when the pollutant-purifying filter 1-1 is formed to be moved in the flow path of the gas by being attracted by the attracting force, it acts also in the moving direction of the pollutant-purifying filter 1-1 It is also possible to easily solve the attracting force by the supporting action of the first supporting body 200, the second supporting body 300-1, the reinforcing member 400 and the like. That is, even if the attracting force for pulling and moving the filter is applied, the attracting force is directly transmitted to the first supporting member 200 and the reinforcing member 400 or the like, and the transmission to the filter body 100 itself can be minimized, The gap holding member 302 of the second support body 300-1 can minimize the change in the shape of the filter body 100 even when a tensile force is applied to the first support body 300-1.

In this way, it is possible to stably maintain the shape of the pollutant purifying filter 1-1 according to another embodiment of the present invention, and thereby to treat pollutants contained in the gas very effectively.

Hereinafter, a filter cartridge according to an embodiment of the present invention will be described in detail with reference to FIG.

10 is a perspective view of a filter cartridge according to an embodiment of the present invention.

10, a filter cartridge 2 according to an embodiment of the present invention includes a shaft 10, a pollutant-purifying filter 1 having one end connected to the shaft 10 and fixed to the shaft 10, And a fastening portion 11 formed on at least one of both ends of the shaft 10 and detachably fastened to a support for supporting the shaft 10. The pollutant purifying filter 1 included in the filter cartridge 2 may be substantially the same as the pollutant purifying filter described above through the different embodiments.

The filter cartridge 2 can be wound around the shaft 10 by winding the pollutant-purifying filter 1 in the form of a roll. The shaft 10 can be rotatably coupled to the housing 20 and the housing 20 can receive and protect the pollutant-purifying filter 1 wrapped around the shaft 10 therein. The shape of the housing 20, the shape of the shaft 10, and the like are illustrative and can be suitably modified as needed.

At least one of both ends of the shaft 10 may have a fastening portion 11 as shown in FIG. The fastening portion 11 can be detachably fastened to a support (for example, a drive shaft connected to a drive portion such as a motor) provided on the installation of the filter cartridge 2 to support the shaft 10 . The fastening portion 11 may include, for example, a stepped structure or the like that can easily contact the entire surface of the shaft 10 with a rotational force by contact with the surface of the shaft. However, the shape of the fastening part 11 need not be limited to this, and it is possible to form the fastening part 11 with various structures that can easily transmit rotational force by detachably coupling the shaft and the shaft. The support may also be formed in a variety of shapes corresponding to the shape of the fastening portion 11.

The pollutant purifying filter 1 can be repeatedly refracted and fixed around the shaft 10 as shown in Fig. Particularly, the refracted edge portions of the pollutant-purifying filter 1 can be arranged in a saw-tooth shape inclined obliquely in a direction which is wound around the shaft 10 and deviates from the radial direction of the shaft 10. [ For example, the second corner portion 120 of the pollutant-purifying filter 1 and the adjacent planar portion 130 may form a refracted corner portion, 10 in the radial direction of the shaft 10 so as to be offset from the radial direction of the shaft 10 in one direction.

That is, the filter cartridge 2 can be wound and compacted more compactly around the shaft 10 in a folded form utilizing the refracted edge portions of the filter 1 for purifying the pollutants. Therefore, the limited space inside the housing 20 can be utilized more efficiently, and a larger amount of the pollutant purifying filter 1 can be wound around the filter cartridge 2 and stored. The detachable filter cartridge 2 can be constructed in this way, and the filter can be compactly stored and can be easily detached and used in the apparatus. In addition, it is possible to perform operations such as exchange, washing, maintenance, and the like very easily.

As described above, the filter 1 for purifying a pollutant is immediately discharged from the shaft 10 by the supporting action and the restoring action by the first support 200, the second support 300, the reinforcing member 400, The shape can be easily restored to a corrugated plate shape. That is, the filter 1 for purifying a pollutant is wound in a roll form in the form of a roll and is compactly stored. When the filter 1 is mounted on a pollutant purification facility or the like, The second supporting member 300, the reinforcing member 400, and the like, and can be easily restored to the three-dimensional shape as described above. This makes it possible to stably maintain the shape of the filter 1 for purifying the pollutants and to treat the pollutants contained in the gas very effectively.
