Abstract

The present invention concerns a fibre-strand-bundle filter in which the inside of a housing is filled with fibre-strand bundles in which the inside of a net is filled with one or more float and a plurality of fibre strands, and, during filtration, the filtration efficiency is increased since pores between fibre strands become smaller while the upper fibre-strand bundles are compressed because of the upwards flotation of the fibre-strand bundles incorporating the floats due to buoyancy, and, during cleaning, the cleaning efficiency is increased since the fibre strands are loosened because of free movement of the fibre-strand bundles due to internal fluid and air.

Filtration efficiency is high due to the small voids between the fiber pieces, and even if the weight of the fiber pieces is contaminated, it does not sink by built-in buoys and maintains constant voids. The present invention relates to a fiber bundle bundle filter in which buoys are relaxed and embedded with high buoyancy.

다음에 이와 같은 본 발명의 섬유조각다발필터의 작용에 대하여 설명한다.Next, the action of the fiber fragment bundle filter of the present invention will be described.

먼저, 도 3에 도시된 바와 같이, 하우징(1)의 유입구(4)를 통하여 유체를 공급하면 내부의 섬유조각다발(7)들이 부력에 의하여 상승하면서 조밀하게 적층된다. 또한, 부표(8)가 부력에 의하여 부상하면서 섬유조각다발(7)들을 더욱 압축시킨다.First, as shown in FIG. 3, when the fluid is supplied through the inlet 4 of the housing 1, the inner fiber bundles 7 are densely stacked while being lifted by buoyancy. In addition, the buoy 8 rises by buoyancy to further compress the fiber bundles 7.

상기 유입구(4)를 통하여 공급되는 유체는 하부지지판(3)의 구멍을 통과한 후 하우징(1) 내부의 공간을 통하여 상승하면서 유체의 유속에 의하여 섬유조각다발(7)을 더욱 압축시키고, 섬유조각다발(7) 내의 섬유조각(10)을 통과 한 후 상부지지판(2)의 구멍을 통하여 배출구(5)로 배출된다.The fluid supplied through the inlet 4 passes through the holes of the lower support plate 3 and then rises through the space inside the housing 1 to further compress the fiber bundles 7 by the flow rate of the fluid, and After passing through the fiber piece 10 in the bundle bundle 7 is discharged to the outlet 5 through the hole of the upper support plate (2).

유체가 조밀하게 압축된 섬유조각(10) 사이를 통과하는 과정에서 유체 속의 부유물질들이 섬유조각(10)에 의하여 걸러져서 제거된다. 이와 같이 섬유조각(10)을 통과하면서 부유물질들이 제거된 처리수는 배출구(5)로 배출된다.As the fluid passes between the densely compressed pieces of fiber 10, the suspended solids in the fluid are filtered out by the pieces of fiber 10 and removed. In this way, the treated water from which suspended matter is removed while passing through the fiber pieces 10 is discharged to the outlet 5.

한편, 섬유조각(10)에 걸린 부유물질들이 증가하면 차압이 상승하게 되고 처리수의 수질이 저하된다. 이러한 경우에는, 도 4에 도시된 바와 같이, 섬유조각다발필터의 운전을 정지하고 유입구(4)를 통하여 압축공기를 공급하여 세정한다. On the other hand, when the suspended solids in the fiber piece 10 increases, the differential pressure is increased and the quality of the treated water is lowered. In this case, as shown in FIG. 4, the operation of the fiber bundle filter is stopped and compressed air is supplied through the inlet port 4 to clean it.

압축공기는 하부지지판(3)의 구멍을 통해 상부로 부상하면서 다량의 공기방물을 형성하여 섬유조각다발(7)들을 유동시켜 섬유조각(10)에 부착되어 있는 부유물질들을 탈리시킨다. 이때 공급된 공기는 배출구(5)를 통하여 배출된다.Compressed air rises through the hole of the lower support plate 3 to form a large amount of air bubbles to flow the fiber bundles 7 to desorb suspended solids attached to the fiber pieces 10. At this time, the supplied air is discharged through the discharge port (5).

이와 같이 압축공기로 세정을 한 후, 도 5에 도시된 바와 같이, 배출구(5)를 통하여 공기를 역으로 공급하여 내부의 유체를 유입구(4)를 통하여 배출시킨다. 이와 같은 압축공기에 의한 세정과 세정유체의 배출을 통하여 섬유조각(10)에 부착되어 있는 부유물질이 제거된다.After washing with compressed air in this way, as shown in FIG. 5, air is supplied back through the outlet 5 to discharge the fluid therein through the inlet 4. The suspended matter adhering to the fiber pieces 10 is removed through the cleaning by the compressed air and the discharge of the cleaning fluid.

도 6에 도시된 순환공정에서는 부유물질을 제거한 후 하부에 위치한 섬유조각다발들을 하부에서 유체를 공급하여 상부로 부상시키고, 섬유조각다발들이 유체의 흐름에 의하여 압밀화되어 공급유체의 부유물질들을 여과할 수 있는 여건을 만들고, 초기운전시에 섬유조각다발에 남아 있는 이물질들을 씻어줄 수 있도록 유체를 일정시간 동안 공급유체탱크(미도시)로 순환시킨다. In the circulating process shown in FIG. 6, after removing the suspended solids, the fiber bundles positioned at the bottom are supplied to the upper portion to supply the fluid, and the fiber bundles are condensed by the flow of the fluid to filter the suspended substances in the supply fluid. Circulate fluid into the supply fluid tank (not shown) for a period of time to allow for clean-up conditions and to wash away any debris remaining in the fiber bundle during initial operation.

한편, 섬유조각다발(7)이 심하게 오염된 경우에는 맨홀(6)을 열어 섬유조각다발(7)을 꺼내어 세탁기와 같은 별도의 세척장치에 넣고 섬유조각다발(7)을 세탁하여 다시 사용 할 수도 있다.On the other hand, if the fiber bundle (7) is severely contaminated, open the manhole (6), take out the fiber bundle (7), put it in a separate washing device such as a washing machine and wash the fiber bundle (7) to use again. have.

종래의 섬유조각필터의 경우에는 섬유조각들이 하나 하나씩 조각으로 분리되어 있어 이를 하우징 내에서 꺼내기도 어렵고, 이것을 별도의 세척장치에 넣고 세척하기 어렵다.In the case of the conventional fiber fragment filter, the fiber fragments are separated into pieces one by one, so that it is difficult to remove them from the housing, and it is difficult to put them in a separate cleaning device and to clean them.

본 발명의 섬유조각다발필터는 종래의 섬유조각필터와는 달리 다수의 섬유조각을 하나의 그물망에 넣어 섬유조각다발을 형성하고 섬유조각다발 내의 부표와 섬유조각의 부력에 의한 부상으로 섬유조각들이 조밀하게 압축되고 섬유조각의 표면에 유체 속의 이물질입자들이 부착되어 제거되는 새로운 개념의 섬유조각필터이다.Unlike the conventional fiber fragment filter, the fiber fragment bundle filter of the present invention forms a fiber bundle by inserting a plurality of fiber pieces into a single net, and the fiber pieces are densified due to the buoyancy and buoyancy of the fiber pieces in the fiber bundle. It is a new fiber fiber filter that is compactly compressed and removes foreign matter particles in the fluid on the surface of the fiber piece.

이와 같이, 본 발명의 섬유조각다발필터는 그물망 내의 섬유조각 자체의 부력에 더하여 부표의 부력으로 섬유조각다발을 상부로 상승시켜 압축시키고, 이러한 압축으로 인하여 내부에 섬유조각다발들이 조밀하게 적층되도록 한 것이어서, 처리수의 수질이 좋게 되고, 압축공기를 사용하는 세정도 효율도 높게 된다.As described above, the fiber bundle bundle filter of the present invention, in addition to the buoyancy of the fiber pieces themselves in the mesh, by raising the fiber bundle bundle to the upper portion by buoyancy buoyancy, and by compression, the fiber bundle bundles are densely stacked therein. As a result, the water quality of the treated water is improved, and the cleaning and efficiency using compressed air are also high.

종래의 섬유조각필터는 세정시에 섬유조각들이 하나씩 분리되어 있어 공기를 사용하거나, 외부의 모터를 이용하여 내부의 회전체를 돌려서 유동시키더라도 섬유조각들이 충분하게 충돌하거나 접촉하지 못하여 세정효과가 떨어지며, 또 이때 내부의 회전체에 의하여 섬유조각의 손상이 발생할 수도 있다.In the conventional fiber fragment filter, the fiber fragments are separated one by one at the time of cleaning, and even if the flow is rotated by using an air or an external motor by rotating the inner rotating body, the fiber fragments do not sufficiently collide or come in contact with the cleaning effect. In this case, damage to the fiber fragments may also occur due to the internal rotating body.

또, 종래의 섬유조각필터는 여과시에 여과체인 섬유조각들이 하나씩 분리되어 있어 여과시에 변형이 일어나기 쉬워서 처리수를 악화시킬 수 있으나, 본 발명의 섬유조각다발필터는 섬유조각 자체 및 부표의 부력으로 섬유조각이 조밀하게 적층되고 그물망 내부에 여과체인 섬유조각과 부표가 갇혀 있어 여과효율이 높게 되고, 세정시에도 섬유조각과 부표의 유동으로 세정효율이 높게 된다.In addition, in the conventional fiber shredding filter, fiber fragments, which are filtration bodies, are separated one by one during filtration, and thus, deformation occurs easily during filtration, which may worsen the treated water. As a result, the fiber fragments are densely stacked and the fiber fragments and the buoys trapped inside the mesh are trapped to increase the filtration efficiency, and the cleaning efficiency is increased due to the flow of the fiber fragments and the buoys.

또한, 본 발명의 섬유조각다발필터는 종래의 섬유조각필터와는 달리 섬유조각을 세정할 때 복잡한 유동장치 및 교반기 등을 사용하는 여러 공정을 거치지 아니하므로 비용이 적게 들고 세정폐액의 발생이 적다.In addition, unlike the conventional fiber fragment filter, the fiber fragment bundle filter of the present invention does not go through various processes using a complicated flow device and agitator when cleaning the fiber fragments, so that the cost is low and the generation of cleaning waste liquid is low.
