Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

The planar filter 100 for water treatment according to an embodiment of the present invention includes a filtration member 110 and a support frame as shown in Figs.

The filtration member 110 is used to filter foreign substances contained in the filtrate such as wastewater, and a known filtration member may be used. However, when the nanofiber web 112 is disposed on both sides of the first support 111 It may be in the form of a plate.

In the present invention, the nanofiber web 112 is for filtering foreign substances contained in the filtrate during passage of the filtrate by the suction pressure, and the first support 111 may be formed of a non- Supporting the web 112 and acting as a movement path through which the filtered water produced by the nanofiber web 112 moves.

At this time, the filter member 110 may have a three-layer structure in which the nanofiber web 112 is directly attached to both surfaces of the first support 111 (refer to FIG. 8 (b)), Layer structure in which a separate second support body 113 is interposed between the web 112 and the first support body 111 (see FIG. 2).

Here, the second support 113 may have a thickness that is relatively thinner than the thickness of the first support 111 to reduce the overall thickness of the filter 110, It can be laminated on one side.

Accordingly, the nanofiber web 112 is attached directly to the first support 111 without being attached to the first support 111, thereby improving adhesion and facilitating adhesion.

For example, the nanofiber web 112 may be attached to the first support 111 via the second support 113 through heat fusion, ultrasonic fusion, high frequency fusion, or the like.

At this time, the second support body 113 may be partially or completely melted and attached to the first support body 111 during the attachment process.

For this, the nanofiber web 112 may have a melting temperature that is higher than the process temperature in the fusing process so as not to be melted by heat, and the second support 113 may have a process temperature To < / RTI > have a lower melting temperature.

Accordingly, the filtration member 110 may be formed in a three-layer structure by completely melting the second support body 113, and only a part of the second support body 113 may be melted to form the nanofiber web 112, 1 structure in which the second support body 113 remains between the first support body 111 and the first support body 111. However, the structure of the filtration member 110 is not limited thereto, and it should be noted that the present invention is not limited to the structure in which one or more supporting layers are interposed between the two nanofiber webs 112.

In addition, the first support 111 and the second support 113 may be porous substrates so that the filtration water produced by the nanofiber web 112 can act as a movement path.

For example, the first support 111 and / or the second support 113 may be any one of commonly known fabrics, knitted fabrics, and nonwoven fabrics, and the nonwoven fabric may be a chemical bonding nonwoven fabric, a thermal bonding nonwoven fabric, A known nonwoven fabric such as a dry nonwoven fabric such as a nonwoven fabric, a nonwoven fabric such as a nonwoven fabric, a nonwoven fabric such as a nonwoven fabric or a nonwoven fabric such as a nonwoven fabric, It is possible to change it.

In other words, the material of the first support 111 and / or the second support 113 is not limited. For example, synthetic fibers selected from the group consisting of polyester, polypropylene, nylon and polyethylene, Lt; / RTI > fibers can be used.

However, it is possible to prevent separation between the first support 111 and / or the second support 113 and the nanofibrous web 112 during application of the water treatment process by improving the binding force with the nanofiber web 112, The first support 111 and the second support 113 may be formed of a low melting point polymer such as a known low melting point polyester and a low melting point polyethylene capable of heat fusion, And a polyolefin low melting point conjugated fiber having a low melting point polyester as a core and a polyethylene terephthalate as a core and a polyester low melting point conjugated fiber and / or a low melting point polyethylene as a core and a polypropylene core as a core .

The melting point of the low-melting point polymer compound may be 60-180 ° C., and the thickness of the first support 111 may be 2-200 μm, but is not limited thereto.

The second support 113 may be made of a different material from the first support 111, but may be made of the same material as the first support 111, It is possible to increase the adhesion with the substrate 111.

The nanofiber web 112 may be formed through nanofibers to filter foreign substances contained in the filtrate. At this time, the nanofibers may include a fiber forming component including polyacrylonitrile (PAN) and polyvinylidene fluoride (PVDF), and an emulsifying agent for improving miscibility of the fiber forming component.

Here, the fiber forming component may include polyacrylonitrile (PAN) and hydrophilic polyvinylidene fluoride (PVDF), both of which have high hydrophilicity.

The PVDF can secure the mechanical strength and chemical resistance of the nanofiber due to the nature of the material. The PAN is hydrophilic, thereby preventing the hydrophobicity of the nanofiber due to the PVDF and improving the hydrophilicity of the nanofiber, An improved water permeability can be exhibited.

Meanwhile, the nanofiber web 112 may include a nanofiber web having a three-dimensional network structure. For example, nanofibers comprising a fiber forming component comprising polyacrylonitrile (PAN) and polyvinylidene fluoride (PVDF) and an emulsifying agent can be laminated perpendicularly to the radiation plane, Due to the solvent which has not been volatilized / evaporated during the fusing process, fusion occurs in the portion of the laminated nanofibers contacting the surfaces of the fibers to form a three-dimensional network structure.

The nanofiber web 112 may be a single layer or may have multiple layers.

At this time, the nanofiber web 112 applied to the present invention may have a relatively larger area than the first support 111 and may be disposed on both sides of the first support 111.

Specifically, the nanofiber web 112 includes a first portion 112a disposed in a region corresponding to the first support 111 so as to cover one surface of the first support 111, And a second portion 112b extending outwardly from the rim of the first portion 112a.

Here, the area of the second portion 112b may be the remaining area of the entire area of the nanofiber web 112 minus the area of the first portion 112a (see FIG. 7).

Thus, when a pair of nanofiber webs 112 are bonded to both sides of the first support 111, the respective nanofibrous webs 112 are separated from the first support 112 by the first support 112, Two portions 112b may be disposed on one surface of the first support 111 so as to protrude outward from the rim of the first support 111 by a predetermined length. Accordingly, the pair of second portions 112b facing each other can be spaced apart from each other by the thickness of the first support body 111. [

The receiving space 125 defined by the width of the pair of second portions 112b facing each other and the thickness of the first supporting member 111 can be formed and on the receiving space 125 side, A support frame for supporting the member 110 in the form of a flat plate can be inserted and disposed.

Here, the width of the accommodation space 125 may have the same width as the width of the frames 120a and 120b (see FIG. 4), and the insertion of the frames 120a and 120b into the accommodation space 125 is smooth The width of the accommodation space 125 may be formed to have a width wider than the width of the frames 120a and 120b (see FIG. 8A).

At this time, the second portion 112b projecting outward from the rim of the first support body 111 may be directly fixed to one surface of the support frame by thermal fusion.

That is, in the present invention, since the support frame for supporting the filtration member 110 is inserted into the accommodation space 125 and is directly fixed to the filtration member 110 through thermal fusion, it is not necessary to use the adhesion member .

For this purpose, the nanofiber web 112 may have a melting temperature that is similar to or lower than the process temperature performed in the fusing process so that at least a portion of the nanofiber web 112 may be melted by heat during thermal fusion with the support frame, May be made of a polymer resin having excellent bonding strength with the nanofiber web 112. [

As a result, the process of applying the adhesive member by hand is omitted, so that productivity of the work can be improved. Further, since the supporting frame is inserted into the receiving space 125, the degree of integration can be improved.

In the case where the filtration member 110 according to the present invention is implemented in a structure having four or more layers in which at least one second support member 113 is interposed between the first support member 111 and the nanofiber web 112, 2 support 113 may have a relatively larger area than that of the first support 111 and may have the same area as the nanofiber web 112.

For example, when the filtration member 110 is implemented as a five-layer structure in which a second support body 113 and a nanofiber web 112 are sequentially stacked on both sides of a first support body 111, 113 may include a fixing portion 113a extending from a plate-shaped body having a predetermined area and disposed in a region corresponding to the second portion 112b of the nanofiber web 112. [

At this time, the second portion 112b may be joined to one surface of the fixing portion 113a. Accordingly, the fixing portion 113a may protrude outward from the rim of the first supporting body 111, like the second portion 112b, and may have a width of a pair of fixing portions 113a facing each other, 1, a receiving space 125 defined by the thickness of the support 111 can be formed.

Here, the area of the fixing portion 113a may be the remaining area of the entire area of the second supporting member 113 minus the area of the fixing portion 113a (see FIG. 7).

A support frame for supporting the filter member 110 in the form of a flat plate may be inserted and arranged on the accommodation space 125 side and a fixing part protruding outward from the rim of the first support member 111 113a may be directly fixed to one surface of the support frame by thermal fusion.

When at least one second support body 113 is interposed between the nanofiber web 112 and the first support body 111, the nanofiber web 112 and the second support body 113 are supported by the support frame 113, And may have a melting temperature that is similar to or lower than the process temperature performed in the fusing process so that at least a portion of the fusing process may be performed by heat during the fusing process with the second support 113, It can be made of an excellent polymer resin.

As described above, the support frame is inserted into the accommodation space 125 and is coupled to the edge of the first support member 111, thereby allowing the filter member 110 to maintain a plate-like shape.

The support frame may be a single member and may support or partially support the edge of the filter member 110. The plurality of frames 120a and 120b may be provided on the edge of the first support body 111 (See Fig. 2).

For example, the plurality of frames 120a and 120b may be disposed on the edge side of the first support body 111 so that one end thereof contacts the other end, The end sides of two adjacent frames 120a and 120b may be connected to each other via the connecting members 130 and 130 'disposed on the first and second connecting members 130 and 130' (see FIG. 10).

However, the shape of the support frame is not limited thereto, and may be changed into various shapes such as a circular shape, arcuate shape, polygonal shape, and a combination thereof depending on the shape of the filter member 110, It is clear that any form is acceptable.

At this time, the support frame supports the filter member 110 in a plate shape, and moves the filtered water produced by the nanofiber web 112 to the receiving opening 133 through a suction force provided from the outside It can serve as a flow path.

Each of the frames 120a and 120b constituting the support frame may be formed in a substantially 'C' shape having one side thereof opened, and the other side of the frames 120a and 120b, (See Fig. 2).

More specifically, the plurality of frames 120a and 120b includes a first plate 121 and a pair of first and second plates 121 and 121 extending in a direction perpendicular to the first plate 121, And the flow path 123 is formed between the pair of second plates 122a and 122b facing each other along the longitudinal direction of the frames 120a and 120b (See FIG. 4).

The frames 120a and 120b inserted into the accommodation space 125 are formed such that the outer surfaces of the second plates 122a and 122b are spaced apart from the second portions 112b of the nanofiber web 112, Or may be integrated with the filtration member 110 by being fixed to the fixed portion 113a of the second support member 113 through thermal fusion.

Here, the flow path 123 may include a first flow path 123a and a second flow path 123b. The first flow path 123a may include a pair of second plates 122a and 122b facing each other, The second flow path 123b may be a space defined by the first plate 121 and the second flow path 123b may be defined by a pair of second plates 122a and 122b facing each other and openings of the frames 120a and 120b (See FIG. 4).

The second flow path 123b may serve as a path for moving the filtered water flowing from the filtration member 110 toward the first flow path 123a. And can serve as a main flow path for the filtered water flowing through the second flow path 123b to move to the receiving port 133 side (see FIG. 11).

The first flow path 123a and the second flow path 123b are formed so that the inner surfaces of the second plates 122a and 122b are stepped surfaces so that the first flow path 123a and the second flow path 123b And the interval between the second plates defining the first flow path 123a may be relatively larger than the interval between the second plates defining the second flow path 123b. However, the shape of the flow path 123 is not limited thereto, and the inner surfaces of the second plates 122a and 122b may be formed in a horizontal plane so that the second plates 122a and 122b between the second plates 122a and 122b defining the first flow path 123a And the interval between the second plates 122a and 122b defining the second flow path 123b may be equal to each other.

On the other hand, at least one protruding portion 124 protruding outside by a predetermined length may be formed on the free end side of the pair of second plates 122a and 122b (see FIGS. 2 and 4).

That is, the protruding portion 124 may protrude along the longitudinal direction of the second plates 122a and 122b on the end sides of the second plates 122a and 122b, When inserted into the space 125, it can be stuck to the edge side of the first support body 111 by an external force

The frame 120a or 120b and the first support member 111 are temporarily fixed to each other to fix the frame 120a or 120b to the second portion 112b or the fixing portion 113a and the frame 120a or 120b, It is possible to prevent the positions of the first and second plates 120a and 120b from being changed.

In the present invention, the frames 120a and 120b are inserted into the accommodating space 125 and then inserted into the second portion 112b of the nanofiber web 112 or the second portion 112b of the second support 113 At least a part of the fixing portions 113a may be fixed to the filtration member 110 by being melted through thermal fusion.

The planar filter 100 for water treatment according to the present invention may include a connection member 130, 130 'coupled to the edge of the support frame.

A plurality of such connecting members 130 and 130 'may be provided, and the ends of the two adjacent frames 120a and 120b may be fixed to the edge of the supporting frame.

The connecting members 130 and 130 'may be directly coupled to the frames 120a and 120b disposed on the edge of the first support 111 and the outer surfaces of the frames 120a and 120b may be bonded to the nano- (See FIGS. 5 and 6) so as to cover the outer surface of the nanofiber web 112 in a state of being covered with the nanofiber web 112.

To this end, the connecting members 130 and 130 'may include a body 131 having one side opened to insert the end sides of the adjacent frames 120a and 120b (refer to FIG. 10).

Accordingly, the two frames 120a and 120b adjacent to each other among the plurality of frames 120a and 120b constituting the support frame are inserted into the body 131, Lt; / RTI >

For example, the end of one of the two frames 120a and 120b adjacent to each other is inserted in the first direction of the body 131, and the end of the other one of the frames 120b is inserted into the body (See FIG. 11) inserted in the second direction of the first frame 131 and in contact with the end of the frame 120a inserted in the first direction.

The flow path 123 formed in the frame 120a inserted in the first direction and the flow path 123 formed in the frame 120b inserted in the second direction are arranged to communicate with each other to form a plurality of frames 120a and 120b Are all communicated with each other.

Here, the first direction and the second direction may be directions orthogonal to each other on the same plane, or may be inclined to have a predetermined angle with respect to one straight line on the same plane.

In the meantime, when the plurality of filters are arranged in parallel to each other, the spacing adjusting member 134 is provided so that the respective filtering members 110 can be spaced apart from each other .

The gap adjusting member 134 may be provided on at least one of the plurality of frames 120a and 120b constituting the support frame, but may be provided to at least one of the connecting members 130 and 130 ' .

For example, the gap adjusting member 134 may include an extending plate 134a having a fastening hole 134b and a spacing member 134c, and may be formed on one side of the connecting member 130 or 130 '.

Specifically, the extension plate 134a may extend outward from the body 131 of the connecting members 130 and 130 ', and a fastening hole 134b through which the fastening bar 240 passes may be formed 9).

Although the fastening holes 134b are illustrated as being formed in the elongated plate 134a in a circular shape, the fastening holes 134b are not limited thereto, and may have a shape corresponding to the cross-sectional shape of the fastening bar 240. For example, the fastening holes 134b may be formed in a circular, arc-like, polygonal cross-section, or a combination thereof.

The spacing member 134c may protrude from the one surface of the extension plate 134a at a predetermined height so as to have a predetermined thickness. The spacing member 134c may surround the edge of the fastening hole 134b as a whole, As shown in FIG.

The spacing member 134c may be formed on both sides of the extension plate 134a or may be formed on only one side of the extension plate 134a and may be formed on one side of the extension plate 134a, As shown in FIG.

Here, the spacing between the plurality of filtration members 110 arranged in parallel to each other may be arranged to have an interval of 3 mm or more, but the present invention is not limited thereto, and the height or thickness of the spacing member 134c may be appropriately changed, . ≪ / RTI >

When the plurality of flat panel filters 100 are connected to each other through the fastening bar 240, the filter member 110 disposed parallel to each other even when the flat panel filters 100 are closely contacted, May be spaced apart through the second end 134c.

Accordingly, when the plurality of flat plate-type filters 100 are arranged in parallel, and the fastening bars 240 are fastened to pass through the fastening holes 134b and the flat plate-type filters 100 are closely contacted with each other, Each of the filter members 110 disposed adjacent to each other may be spaced apart at a predetermined interval through the spacing member 134c (see FIG. 14).

That is, when the planar filter module 200 is constructed by using the plurality of flat panel filters 100, if the flat panel filters 100 connected to the fastener bar 240 are closely contacted with each other, Uniform spacing may be formed between the filtration members 110 by the spacing member 134c and if fastening members such as nuts are fastened to both sides of the fastening bar 240, The spacing formed between the filtration members 110 of the filter member 110 can be maintained.

Accordingly, the flat type filter module 200 can be provided with the filtration member 110 on both sides of the filtration member 110 by the suction force provided from the outside because the filtration liquid may exist on both sides of the respective filtration members 110, So that the filtered water can be produced.

In addition, when backwashing is performed to remove foreign matters adhering to the filtration member 110 after repeated production of filtered water, the pressure of the fluid such as washing water supplied from the outside causes the filtration member 110 May be separated and then fall into a space between adjacent filter elements 110. In this case,

At least one of the connecting members 130 and 130 'is provided with a receiving opening 133 for discharging the filtered water moved along the flow path 123 formed in each of the frames 120a and 120b to the outside .

That is, the connection member 130 ', in which the receiving opening 133 is not formed, of the plurality of connection members 130 and 130' coupled to the edge of the support frame only serves to connect a pair of adjacent frames Meanwhile, the connection member 130 having the receiving opening 133 may serve as a drain for discharging the filtered water produced through the receiving opening 133 to the outside (see FIGS. 1 and 2).

Here, the receiving opening 133 may be provided only in one of the plurality of connecting members, but it is preferable that the receiving opening 133 is provided in the two connecting members 130 to provide an equal suction pressure toward the filtering member 110 .

The receiving opening 133 may be integrally formed with the body 131 of the connecting member 130 as shown in FIG. 10, but the connecting hole 130a may be formed in the body 131 of the connecting member 130, And a receiving hole 133 having a predetermined length may be detachably coupled to the coupling hole 131a (see FIG. 12).
