Description

[0001] Dust collecting filter and dust collector [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting filter and a dust collecting apparatus, and more particularly, to a dust collecting filter improved in filter structure and improved in dust collecting ability and a dust collecting apparatus including such a dust collecting filter.

A filter is used to treat pollutants such as dust. The filter may be used for household use or for industrial use. Particularly, industrial filters are able to collect a large amount of pollutants by being exposed to extreme environments such as flue gas. The filter can collect and collect contaminant particles through the pores. The filter can treat contaminant particles through mechanisms such as sieving, inertia impaction, diffusion, interception, and the like.

In particular, the mechanism of inertial collision and diffusion can be a major factor in the treatment of pollutants. The contaminant particles entering the pores can be attached to the filter tissue by inertial collision and diffusion and can be removed from the vessel. The size, uniformity of the pores, the ventilation structure around the filter and the like can determine the pollutant treatment ability of the filter and greatly affect the treatment effect.

BACKGROUND ART Conventionally, a bag filter or the like has been widely used as a method for treating contaminants such as dust. The particulate pollutants were treated by applying a bag filter made of nonwoven fabric or the like to a power generation facility where a large amount of dust or pollutants are generated. However, in the case of the conventional filter, the voids are not uniform and the size is not appropriate, so that the pollutant treatment is not effective. In addition, the conventional filter is difficult to be stably supported in the inside of the flue and the like in response to an increasing back pressure, and it is also difficult to change the arrangement or adjust it appropriately in accordance with the operation conditions of the equipment.

Is provided to fully convey the scope of the invention to those skilled in the art, and the present invention is only defined by the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, a particulate 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 showing a filter body portion of a dust collecting filter according to an embodiment of the present invention, FIG. 2 is an enlarged view showing the filter body portion before and after the formation of a gap adjusting member, FIG. 4 is a view showing a modification example of the filter body of FIG. 1 and a modification example in which the auxiliary filter body is superimposed on the filter body. FIG. 5 is a cross- FIG. 4 is a perspective view illustrating a filter body portion and a reinforcing member of a dust collecting filter according to an embodiment of the present invention.

Referring to FIGS. 1 to 5, a dust filter (see 1 in FIG. 5) according to an embodiment of the present invention is formed by connecting a part of the dust collecting filter A filter body 100 including a connection structure 120 and a cavity 110 formed between the connection structures 120 and including a plurality of fluid flow spaces having different cross sectional areas; A gap adjustment member 200 that extends between the connection structures 120 to reduce the cross-sectional area of the fluid flow space, the thickness of which is formed corresponding to the gap between the connection structures 120 to reduce the difference in cross- .

The void adjusting member 200 extends between the connecting structures 120 forming the filter structure of the filter body 100 as shown in Figs. 1 and 2 (b) (see the hatched portion). As shown in FIG. 2 (a), a fluid-flowable space is formed between the mutually spaced connection structures 120, and the gap adjustment member 200 reduces the cross-sectional area of the fluid flow space. Accordingly, the size of the gap 110 including a plurality of fluid flow spaces having different cross-sectional areas can be appropriately adjusted. In particular, the void regulating member 200 does not simply reduce the size of the fluid flow space collectively but is formed to correspond to the gap between the connection structures 120, thereby reducing the cross sectional area difference of the different fluid flow spaces . As a result, the size of the voids 110 distributed throughout the dust filter 1 can be effectively uniformed and the dust collecting performance of the filter can be greatly improved.

In addition, since the size of the air gap 110 is more uniformly formed throughout the dust filter 1 due to the gap adjusting member 200, a more uniform dust collection effect can be obtained and a pressure distribution acting on the filter becomes more uniform So that a smooth dust collecting effect can be obtained. In addition, by controlling the size of the gap 110, contaminant particles of a smaller size can be easily removed.

In addition, the void adjusting member 200 may comprise an adhesive material that adheres to the connecting structure 120, wherein the adhesive material remains sticky even after being attached to the connecting structure 120. That is, the gap adjusting member 200 may be formed of an adhesive material including an adhesive material, thereby imparting an adhesive force to the dust filter 1. 5, the stiffener 300 includes a stiffener 300 connected to the filter body 100 to support the filter body 100. The stiffener 300 enhances the overall holding force of the dust filter 1, ) Can be greatly improved. With this improved structure, the dust collecting performance and stability of the dust collecting filter 1 can be greatly improved.

Hereinafter, the particulate filter 1 having such characteristics will be described in more detail with reference to the respective drawings. Other features of the present invention will be apparent from the following description.

The filter body 100 may be formed in a flat sheet shape as shown in Fig. The filter body 100 is refractable and can be wound on a shaft and wound or unwinded in a roll form. The filter body 100 includes a microstructure consisting of a connecting structure 120 as shown in FIGS. 1 and 2, and the microstructure forms a filter structure. The filter structure can be variously formed according to the embodiment of the connection structure 120. The connection structure 120 may be formed in a form including at least a part of the fibers which are mutually intersected and connected as shown in the figure. The filter tissue may be formed in an irregular shape formed by cross-woven fabrics of such fibers. The filter tissue may form a structure, for example, a nonwoven fabric made of fibers crossed with each other.

The filter body 100 need not be limited to the shape shown in Fig. The filter body 100 may be deformed in a suitable form as required. The filter body 100 may be deformed into a shape including, for example, a refracting portion at least partially refracted and formed. It is also possible to form a dust filter in which the filter body 100 and the auxiliary filter body 100c are overlapped by including an auxiliary filter body (see 100c in FIG. 4) that can be overlapped on the filter body 100. FIG. This will be described in more detail below.

The space between the connection structures 120 is opened to form a space capable of fluid flow. The fluid flow space may be formed differently in cross-sectional area (for example, it may be measured as the area of the plane surrounded by the connection structure) corresponding to the interval between the connection structures 120 and the like. 2 (a), due to the irregular connection structure between the connection structures 120 before the gap regulating member 200 is formed, a difference in cross-sectional area between the connection regulating member 120 and the gap regulating member 200 A flow space can be formed. The cavity 110 may comprise all or a portion of this fluid flow space.

 The void adjusting member 200 is attached to the connecting structure 120 as shown in Figs. 1 and 2 (b). The gap adjustment member 200 extends between the connection structures 120 as shown and is interposed within the fluid flow space. Thus, the cross-sectional area of the fluid flow space is reduced and the size of the voids 110 is appropriately adjusted. 2 (b), the gap adjusting member 200 may be formed to be connected along the connecting portion of the connecting structure 120 and may include a portion attached to the connecting structure 120, And a portion extending into the space between the first and second plates. The void adjusting member 200 may be made of an adhesive material attached to the connecting structure 120 and may be easily attached to the connecting structure 120.

In particular, the void regulating member 200 may have a thickness (e. G., Measured as the distance between the surface of the void regulating member and the surface of the connecting structure to which the void regulating member is attached, as shown in Figures 1 and 2 (b) For example, can be measured as a linear distance from a point on the coupling structure surface to a point at which a straight line perpendicular to the coupling structure surface intersects the surface of the gap adjustment member) So that the difference in cross-sectional area of the fluid flow space can be effectively reduced. The void regulating member 200 may be formed extending from the connecting structure 120 to the space between the connecting structures 120 as shown and at least a portion of which may be increased in proportion to the spacing between the connecting structures 120 have. That is, when the gap between the connection structures 120 is relatively large, the thickness of the gap adjustment member 200 is also increased so that the cross-sectional area reduction amount of the fluid flow space is increased, The thickness of the gap adjusting member 200 may be reduced to reduce the sectional area reduction amount of the fluid flow space.

2 (a), even if a non-uniform fluid flow space having a relatively large difference in sectional area is formed between the connection structures 120, as shown in FIG. 2 (b), the connection structure 120 It is possible to form a void adjusting member 200 whose thickness varies in accordance with the interval between the gap adjusting members 200 and 200 to obtain a more uniformized void 110 structure in which the sectional area difference is relatively reduced. In particular, such a structure may be more effective when the connecting structure 120 is made of fibrous material to form a filter structure that is very irregularly cross-woven. As a result of the structure including the gap adjusting member 200, the space between the connecting structures 120 can be appropriately reduced and the uniformed void 110 can be formed on the entire filter body 100.

The gap adjusting member 200 can be easily formed in the manner as shown in FIG. The void regulating member 200 may be made of an adhesive material attached to the connecting structure (see 120 in FIGS. 1 and 2) as described above. The gap adjusting member 200 may be formed by pressurizing the adherent material (see the dotted arrow) in the form of particles in the filter body 100 as shown in FIG. 3A. By applying pressure to the filter body 100 to spray the adherent material in powder form, it induces scattering of the particulate adherent material and attaches the scattered particles to form a void adjusting member (200) can be formed. The adhesive material can be injected through the injection nozzle A into the form of particles.

Also, the gap adjusting member 200 may be formed by inducing a pressure difference between both surfaces of the filter member 100. For example, one surface of the filter body 100 to which an adhesive material (see a dotted line arrow) is sprayed as shown in FIG. 3 (b) is pressed, while the other surface is maintained at a pressure lower than that of the filter body 100 The gap adjusting member 200 can be formed by inducing a pressure difference between both surfaces of the gap adjustment member 200. [ As shown in the figure, one side of the filter body 100 is pressurized by using the injection nozzle A, and the other side of the filter body 100 is sucked by using the suction nozzle B, so that the pressure can be relatively kept low. In this case, the adhesive material granulated by the pressure difference can be more easily introduced into the space between the connection structures 120.

In addition, when the pressure difference is appropriately changed, the inflow amount of the adhesive material is maintained at a relatively wide interval between the connection structures 120, and relatively inflow is maintained at a point where the interval between the connection structures 120 is narrow. The resistance is greatly increased and the inflow amount of the adhesive material can be naturally reduced. Thus, the supply amount of the adhesive material can be naturally adjusted in proportion to the distance between the connection structures 120. Therefore, the gap adjusting member 200 having a thickness corresponding to the gap between the connection structures 120 can be formed more easily. In this way, the gap adjusting member 200 can be formed very easily.

The gap regulating member 200 may be formed of the following materials. For example, starch, carbohydrates, glucose, sugar, oligosaccharides, dietary fibers, cellulose, hemicellulose, pectin, chitin, chitosan, carrageenan, polydextrose, (meth) acrylic acid esters, vinyl esters, unsaturated acetates, At least one selected from the group consisting of methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, hexyl acrylate, heptyl acrylate, octyl acrylate, 2-ethylhexyl acrylate, (200) can be formed.

The dust filter having the gap adjusting member can be manufactured as follows. Hereinafter, an embodiment will be described.

≪ Example 1 >

Adhesive substances were prepared by mixing 850 g of n-butyl acrylate (n-BA) per 2,000 mL of toluene and sprayed evenly onto the filter with a nozzle (using an air flow nozzle) using a metering pump. The filter body was formed of a polyethylene nonwoven fabric, and the size of the nonwoven fabric was formed to be 100 (cm) x 5,000 (cm) x 5 (mm) in width x length x thickness. The nonwoven fabric was prepared by primary drying with air having a flow rate of 5 m / sec or more. Thereafter, the filter body on which the adhesive material was sprayed was allowed to stand at 80 DEG C for 5 minutes and then dried at 140 DEG C for about 2 minutes. This process was repeated four times.

≪ Example 2 >

300 g of starch was mixed with water and heated with stirring for about 20 minutes to prepare an adhesive material and sprayed evenly onto the filter body with a nozzle (using an air flow nozzle) using a metering pump. The filter body was formed of a polyethylene nonwoven fabric, and the size of the nonwoven fabric was formed to be 100 (cm) x 5,000 (cm) x 5 (mm) in width x length x thickness. Thereafter, the filter body on which the adhesive material was injected was dried at room temperature with air having a flow rate of 0.5 m / sec or more.

Dust (having a particle diameter of 3 μm or less was used) was forcibly injected into the dust collecting filter of Example 1 and the dust collecting performance was measured. As a result, the dust collection efficiency was measured as 51, 65, and 84 percent for three different samples, respectively. The dust collection efficiency was calculated as a percentage of the filter weight after the dust collection and the filter weight difference before the dust collection. It was confirmed that as measured, the dust collection efficiency was as high as 84 percent.

1 and 2) of the filter body (see 100 in FIG. 1 and FIG. 2) is adjusted by the gap adjusting member (see 200 in FIGS. 1 and 2) Can be manufactured. Also, as described above, the gap adjusting member 200 is formed of an adhesive material to uniformly adjust the size of the gap 110, thereby providing an adhesive force to the filter and maximizing the trapping ability of the pollutant particles. Hereinafter, an embodiment of the present invention will be described with reference to a case where the adhesive material constituting the gap adjusting member 200 is formed of an adhesive material that maintains tackiness even after it is attached to the connecting structure (see 120 in FIGS. 1 and 2) It proceeds.

However, the adhesive material need not be limited to such an example, and the adhesive material may be formed of a material that is attached to the connection structure 120 and then hardened without being tacky or hardened. In this case, it is also possible to form an adhesive layer formed by applying an adhesive material to at least a part of the filter element 100. In such a case, at least a part of the adhesive layer may be formed to overlap with the void adjusting member 200 and easily collect the contaminant particles flowing between the voids 110 at a position overlapped with the void adjusting member 200 . The adhesive material may include at least one selected from, for example, a silicone resin and an acrylic resin.

On the other hand, the filter body 100 can be appropriately deformed as described above. As shown in FIGS. 4 (a), 4 (b) and 4 (c), the filter member 100 may be deformed into a shape including at least a refracted portion formed by refraction. 4 (d), it is also possible to form the dust filter in a form including the auxiliary filter body (see 100c in FIG. 4) which is superimposed on the filter body 100. As shown in FIG. 4 (a) and 4 (b), the refracting portion includes a bent portion 100a formed by bending at least a part of the filter member 100, And at least one of the extended portions 100b formed by extending at least a part of the body 100 in the form of a bag. Although the bent portion 100a and the extended portion 100b are shown separately, it is also possible to form the bent portion 100a and the extended portion 100b together if necessary.

The filter body 100 may be formed in a zigzag shape as shown in Fig. 4 (a) depending on the arrangement and formation method of the bent portion 100a, and the filter body 100 may be formed in a zigzag shape as shown in Fig. 4 (b) As shown in FIG. In addition, by forming the bag-like extension portion 100b, a bag-like processing structure may be formed in a three-dimensional shape connected to a plane as shown in Fig. 4 (c). By forming it like this, the surface area of the filter member 100 can be effectively increased. The surface of the filter body 100 may be appropriately increased by forming a refracting portion having a different shape on the filter body 100 as necessary. This makes it possible to treat the contaminants more effectively by increasing the contact area in contact with the gas or the like.

Also, as shown in FIG. 4 (d), the auxiliary filter body 100c superimposed on the filter body 100 may be formed. The auxiliary filter element 100c may also include voids, but the auxiliary filter element 100c may not have the void adjusting element described above. The auxiliary filter body 100c can be overlapped with the filter body 100 to obtain an additional dust collecting effect. 4D shows an example in which the filter body 100 and the auxiliary filter body 100c are formed one by one and overlap each other. However, one or more than one filter body 100 and the auxiliary filter body 100c are formed They can overlap each other. That is, it is possible to form an auxiliary filter body 100c that can be overlapped on the filter body 100, and one or more filter body 100 and auxiliary filter body 100c may be formed to form a dust filter that is overlapped with each other.

As described above, the filter body 100 may be formed in the above-described flat sheet shape, or the filter body 100 may be modified to have a refracting portion, or the auxiliary filter body 100c may be superimposed on the filter body 100 So that various types of dust collecting filters can be formed. The remaining part of the dust filter will be described in more detail with reference to the filter member 100 formed in a flat sheet shape as shown in FIG. 1 according to an embodiment of the present invention.

Hereinafter, the structure of the entire dust filter including the stiffener will be described in more detail with reference to FIG.

The dust collecting filter 1 according to the embodiment of the present invention is configured such that the stiffener 300 as shown in Fig. 5 is connected to the filter body 100 having the gap adjusting member (see 200 in Fig. 1 and Fig. 2) . The stiffener 300 is connected to the filter body 100 to form a support structure for stably supporting the filter body 100. The structural stiffness of the filter body 100 is greatly increased by connecting the stiffener 300 to the filter body 100. The reinforcing material 300 may include, for example, metal yarns, glass fibers, reinforcing fibers, various high molecular materials having improved rigidity and heat resistance, and the like.

The stiffener 300 may be formed to include a lattice structure as shown in Fig. 5A, and the lattice structure may be a fixed lattice structure, for example. The fixed lattice structure may mean that the lattice structure is not deformed such as increasing or decreasing, and the lattice structure is originally maintained. The stiffeners 300 may be formed in a continuous lattice shape as shown in FIG. 5 (a) and arranged in a continuous net shape (or mesh shape) so that the filter body 100 may be connected to at least a part of the stiffeners 300 . In this way, the filter body 100 and the stiffener 300 are connected to each other to form a rigid filter structure having high durability. The filter body 100 can be formed only in the entire region of the stiffener 300, or a part thereof, and can be adjusted as necessary.

At least a part of the stiffener 300 may be bonded to the surface of the filter body 100, or may be bound and connected as shown in Figs. 5 (b) and 5 (c). That is, the stiffener 300 can be attached to the surface of the filter body 100 and easily connected to the filter body 100. However, the present invention is not limited thereto, and the reinforcing member 300 may be inserted through the inside of the filter body 100 if necessary. Also, the arrangement of the stiffeners 300 may be modified appropriately by a zigzag shape instead of a lattice structure. The shape of the stiffener 300 may also be formed into a wire shape that is linearly shaped as shown in the figure, but may be deformed into a band shape having a constant width if necessary.

A bonding portion 310 including an adhesive material may be formed between the stiffener 300 and the filter member 100 as shown in FIG. Also, as shown in FIG. 5 (c), a binding portion 320 for binding at least a part of the stiffener 300 may be formed and interconnected in a binding manner. For example, the bundling unit 320 may be formed in such a manner that a bar yarn made of high-strength flame-retardant fiber is sewn around the reinforcing member 300 and bound to the filter member 100. [ 5 (a) shows an example of connecting with a bonding method, but it is also possible to connect the bonding method and the binding method by mixing. The connection structure, the connection shape, the arrangement, and the like may be appropriately modified to the extent that the stiffener 300 is adhered to or bonded to the surface of the filter body 100.

The structure including the stiffener 300 allows the dust filter 1 to be supported more stably and the air gap 110 of the dust filter 1 can be more reliably supported by the structure including the gap adjustment member 200 And the dust collecting performance can be greatly improved. The dust filter 1 of the present invention may be realized in another form having high usability based on such a structure. Hereinafter, other and further embodiments of the present invention will be described.

Hereinafter, a particulate filter according to another embodiment of the present invention will be described in detail with reference to FIG. In the following description, the same reference numerals will be used throughout the drawings to refer to the same or like parts.

Referring to FIG. 6, the dust filter 1-1 according to another embodiment of the present invention includes a filter body 100, a gap adjusting member (see 200 in FIGS. 1 and 2), and a stiffener 300 And a ventilation area 12 formed at least a part of the dust collection area 11 but not the dust collection area 11 are formed. The dust collecting filter 1-1 may be used to perform a dust collecting operation as required or to perform other operations corresponding to the operation state of the facility. Preferably, the dust-collecting filter 1-1 according to another embodiment of the present invention further includes a blocking member 400 for blocking the flow of fluid, and the dust- A shielding region 10 including a shielding member 400 may be formed.

Thus, dust collecting operation, shielding operation, ventilation operation, and the like can be performed using the dust filter 1-1, and the operation of the facility can be performed It is possible to cope with dust collection, to shield the flow path, or to assist smooth fluid flow during power generation. That is, the structure of the dust filter 1-1 can be expanded on the basis of the structure described above to form the highly efficient dust filter 1-1 applicable to various situations. Specific examples of application will be described in more detail in the following description of the dust collecting apparatus.

The dust collecting filter 1-1 according to another embodiment of the present invention is configured such that the dust collecting area 11, the ventilation area 12 and the shielding area 10 are arranged on a single single sheet as shown in Fig. 6 . That is, the dust collection area 11, the ventilation area 12, and the shielding area 10 are arranged in this order on the dust filter 1 - 1 formed of a single sheet.
