Description

회전 구동 방식 공극제어형 섬유여과장치Rotation driven pore control type fiber filtration device
본 발명은 물속의 부유물질, 탁도, BOD, COD, 총인을 제거하는 여과 장치에 관한 것으로서, 보다 상세하게는, 여과조 내에 다수의 섬유여재를 다층 구조로 장착하여 여층을 형성하고 상기 섬유여재를 회전 구동에 의한 비트는 방식으로 여재 공극의 크기 또는 여층의 공극율을 원하는대로 조절 제어할 수 있는 회전 구동 방식 공극제어형 섬유여과장치에 관한 것이다.The present invention relates to a filtration device that removes suspended solids, turbidity, BOD, COD, and total phosphorus in water. More specifically, a plurality of fiber filter media is mounted in a multi-layer structure in a filtration tank to form a filter layer, and the fiber filter media is rotated. It relates to a rotational drive type pore control type fiber filtration device that can adjust and control the size of filter media pores or the porosity of the filter layer as desired by driving and twisting.
최근, 여과 장치의 성능을 보다 향상시키기 위하여 섬유사를 여재로 사용하여, 여과기의 하단에 섬유사를 고정시켜 원수 공급압력으로 여재를 압착시키고, 공기와 세척수 공급압력으로 여재를 팽창시키는 여과장치가 개발(등록번호 10-0241198)되어 있으나, 이 방법은 여층이 단층이고 여재의 압착 정도가 원수 공급압력에 의하여 결정되기 때문에, 부유물질의 포획공간이 적어 여과지속시간이 짧고 세척빈도가 잦으며 유입수의 수질변동에 대처하기가 쉽지 않아 목적하는 수질과 수량을 임의로 조절하기가 어렵다. Recently, in order to further improve the performance of the filtration device, a filtration device has been developed that uses fiber yarn as a filter medium, fixes the fiber yarn at the bottom of the filter, compresses the filter media with raw water supply pressure, and expands the filter media with air and washing water supply pressure. Although developed (registration number 10-0241198), this method has a single-layer filter layer and the degree of compression of the filter media is determined by the raw water supply pressure, so the space for trapping suspended solids is small, so the filtration duration is short, the frequency of washing is frequent, and the inflow water It is not easy to cope with changes in water quality, making it difficult to arbitrarily control the desired water quality and quantity.
또한, 여재를 피스톤에 의하여 수직 방향으로 압착하고 이완시키기 때문에 장시간 사용하면 여재의 손상이 우려되며, 피스톤을 작동시켜야하는 별도의 동력전달 장치가 필요하다.In addition, because the filter medium is compressed and relaxed in the vertical direction by a piston, there is a risk of damage to the filter medium if used for a long time, and a separate power transmission device is required to operate the piston.
그리고, 섬유사를 수직방향으로 당겨서 공극을 제어하는 방식은 여층이 균일하게 형성되지 못하고 섬유사 다발 사이가 벌어지는 현상으로 인해 여과효율이 낮아지는 문제가 있다.In addition, the method of controlling the air gap by pulling the fiber yarn in the vertical direction has the problem of lowering the filtration efficiency due to the phenomenon in which the filter layer is not formed uniformly and the space between the fiber bundles is widened.
한편, 일부 비틀림 방식의 여과기의 경우 방사형 회전 정도와 방향에 따라 여재가 여재걸대 상판과 여재걸대 하판를 따라 중앙으로 모이면서 한쪽 또는 양쪽이 서로 반대 방향으로 비틀려 중심축에 위치한 다공관 주위로 집중되거나 원래의 상태로 복원되도록 하여 여재와 여재 사이에 형성되는 공극의 크기를 필요한 만큼 조절하면서 여과 및 역세 조작을 구성하고 있으나, 실제 방사형 여재걸대의 각도와 섬유여재 고리의 마찰로 인해 섬유여재가 다공관 주위로 집중 되지 못하는 문제점이 있어 그 효과가 미미하다.Meanwhile, in the case of some torsion filters, depending on the degree and direction of radial rotation, the filter media gathers at the center along the upper plate and lower plate of the filter plate, and one or both sides are twisted in opposite directions and concentrated around the porous tube located on the central axis. Filtration and backwashing are performed by adjusting the size of the voids formed between the filter media as necessary to restore it to its original state. However, in reality, due to the angle of the radial filter holder and the friction of the fiber filter ring, the fiber media becomes porous. There is a problem with not being able to focus on the surrounding area, so the effect is minimal.
게다가, 여과기 상부에는 비틀림 방식을 구현하기 위해 서퍼기어, 레커기어, 에어실린더, 볼부쉬 등을 많이 부품이 사용되고 있으며, 상부여재걸대를 회전(비틀기)시키기 위해 한쪽 방향에서만 실린더의 힘을 전달하여 상부 축에서 누수현상이 발생하는 단점이 나타나고 있는 실정이다.In addition, many parts such as surfer gears, wrecker gears, air cylinders, and ball bushings are used in the upper part of the filter to implement the twisting method. In order to rotate (twist) the upper filter rack, the force of the cylinder is transmitted in only one direction to the upper filter.

At this time, the force twisting the fiber media 40 is determined according to the set pneumatic pressure supplied to the rotary cylinder 50.
이후, 여과조(100)의 내부로 유입된 원수(W0)가 여층(41)에 의해 여과된 후 다공관(10) 내부로 유입되고 다공관(10) 내부로 유입된 처리수(W1)는 처리수 배출관(140)을 통해 외부로 배출된다. Thereafter, the raw water (W0) flowing into the filtration tank (100) is filtered by the filter layer (41) and then flows into the porous pipe (10), and the treated water (W1) flowing into the porous pipe (10) is treated. It is discharged to the outside through the water discharge pipe 140.
본 발명의 역세 공정 시, 회전형 실린더(50)의 구동에 의해 여재걸대 상판(20)이 타 방향(반대 방향)으로 회전하여 섬유여재(40)가 원래 상태로 복원된 상태(도 1과 도 3 상태)에서 또는 실린더 제어부(60)의 제어에 의해 여재걸대 상판(20)이 일 방향 회전(또는 시계방향 회전)과 타 방향 회전(또는 반시계방향 회전)을 반복하여 섬유여재(40)가 다공관(10)을 중심으로 감기고 복원되는 과정이 반복되면서, 역세수 유입구(160)를 통해 다공관(10)의 내부로 유입된 역세수(W)가 다공관(10)의 외부로 배출되는 동시에 여과조(100)의 하부에서 상기 섬유여재(40)를 향해 역세공기(G)가 분사된다.During the backwashing process of the present invention, the filter media rack top plate 20 is rotated in the other direction (opposite direction) by driving the rotary cylinder 50, and the fiber media 40 is restored to its original state (FIGS. 1 and 2). 3 state) or under the control of the cylinder control unit 60, the top plate 20 of the filter media rack repeats rotation in one direction (or clockwise rotation) and rotation in the other direction (or counterclockwise rotation), so that the fiber media 40 As the process of winding and restoring around the porous pipe 10 is repeated, the backwash water (W) flowing into the inside of the porous pipe 10 through the backwash water inlet 160 is discharged to the outside of the porous pipe 10. At the same time, a backwash machine (G) is sprayed from the lower part of the filtration tank 100 toward the fiber filter medium 40.
일단, 본 발명의 장치는 역세 공정시, 실린더 제어부(60)를 통해 섬유여재(40)를 비틀리지 않은 원래 상태로 복원시킨 상태에서 역세 또는 역세척을 수행하거나 섬유여재(40)를 시계 방향과 반시계 방향으로 반복적으로 회전시키면서 역세 또는 역세척을 수행하도록 제어될 수 있다. First, during the backwashing process, the device of the present invention performs backwashing or backwashing in a state in which the fiber media 40 is restored to its original, undistorted state through the cylinder control unit 60, or the fiber media 40 is rotated in a clockwise direction. It can be controlled to perform backwashing or backwashing while repeatedly rotating counterclockwise.
또한, 역세 공정시, 섬유여재(40) 하부 바로 아래에서 역세 공기(G)가 분사되도록 구성되어, 역세 공기(G)에 의한 섬유여재(40)의 역세 또는 역세척이 매우 효과적으로 수행될 수 있다. In addition, during the backwashing process, backwashing air (G) is configured to be sprayed directly below the lower part of the fiber media 40, so backwashing or backwashing of the fiber media 40 by the backwash air (G) can be performed very effectively. .
이에 대해, 보다 구체적으로 설명하면, 상기 여재걸대 상판(20)과 여재걸대 하판(30)에는 도 4와 도 5와 같이 다수의 결합공(21, 31)이 각각 형성되고, 상기 여재걸대 하판(30)에는 도 5와 같이 다수의 역세공기 분사공(32)이 더 형성되는데, 바람직한 실시예로서, 상기 역세공기 분사공(32)은 한 쌍의 여재걸대 하판 결합공(31) 사이에 형성될 수 있다. To explain this in more detail, a plurality of coupling holes 21 and 31 are formed in the upper plate 20 and the lower plate 30 of the filter rack, respectively, as shown in FIGS. 4 and 5, and the lower plate of the filter rack ( 30), a plurality of backwash injection holes 32 are further formed as shown in FIG. 5. In a preferred embodiment, the backwash spray holes 32 are formed between a pair of filter rack lower plate coupling holes 31. You can.
그 결과, 섬유여재(40) 하부가 여재고리(70)를 통해 여재걸대 하판(30)에 연결되면 섬유여재(40)의 하부 바로 아래에 역세공기 분사공(32)이 위치될 수 있게 되면서, 도 7에 도시된 바와 같이 역세 공기(G)가 직접적으로 섬유여재(40)의 하부를 향해 분사되게 되므로, 역세 공기(G)에 의한 섬유여재(40)의 역세(척) 효과가 매우 향상되게 된다. As a result, when the lower part of the fiber media 40 is connected to the lower plate 30 of the filter rack 30 through the filter ring 70, the backwash air injection hole 32 can be located directly below the lower part of the fiber media 40, As shown in FIG. 7, since the backwash air (G) is sprayed directly toward the lower part of the fiber media 40, the backwash (chuck) effect of the fiber media 40 by the backwash air (G) is greatly improved. do.
역세 공기(G)는 역세공기 유입관(80)을 통해 장치 내부로 유입되어 여재걸대 하판(30)의 역세공기 분사공(32)을 통해 분사될 수도 있고, 여과조(100)의 하측 또는 여재걸대 하판(30)의 하측에 마련되는 역세공기 분사노즐(도시 생략)에서 공급되는 역세 공기가 역세공기 분사공(32)을 통해 분사될 수도 있다.The backwash air (G) may be introduced into the device through the backwash air inlet pipe 80 and sprayed through the backwash air injection hole 32 of the lower plate 30 of the filter tank 100 or the filter rack holder. Backwash air supplied from a backwash air injection nozzle (not shown) provided on the lower side of the lower plate 30 may be sprayed through the backwash air injection hole 32.
또한, 본 발명의 바람직한 실시예로서, 상기 여과조(100)의 내부 상측에는 여과조의 내주를 따라 월류 유수로(110)를 형성하기 위한 월류 유도벽(101)이 구비된다. In addition, as a preferred embodiment of the present invention, an overflow guide wall 101 is provided on the inner upper side of the filtration tank 100 to form an overflow flow path 110 along the inner circumference of the filtration tank.
상기 월류 유도벽(101)은 여과조 (100) 내부에서 소정 수위 이상으로 상승한 물 즉, 상기 월류 유도벽(101)을 월류(overflow)한 물을 월류 유수로(110)를 통해 역세수 배출관(120)으로 배출되도록 유도하는 것이다. The overflow guide wall 101 allows water that has risen above a predetermined water level inside the filtration tank 100, that is, water overflowing the overflow guide wall 101, to pass through the overflow flow path 110 to the backwash water discharge pipe 120. ) to induce it to be discharged.
역세수 배출관(120)이 여과조(100)의 상부 일측에 구비되면 반대쪽(타측) 부위의 역세수는 반대편에 있기 때문에 상대적으로 역세수 배출관(120)을 통해 배출되기가 어렵기 때문에, 본 발명에서는 이러한 문제점을 해결하기 위해 여과조(100) 내부 상측에 역세수 배출관(120)과 연통되는 월류 유수로(110)를 내주를 따라 형성하여, 월류 유도벽(101)을 월류만 하면 역세수 배출관(120) 반대측 부위라도 월류 유수로(110)를 통해 원활하게 역세수 배출관(120)으로 배출될 수 있게 된다. When the backwash water discharge pipe 120 is provided on one upper side of the filtration tank 100, it is relatively difficult for the backwash water from the opposite side (the other side) to be discharged through the backwash water discharge pipe 120 because it is on the opposite side. In the present invention, In order to solve this problem, an overflow flow path 110 communicating with the backwash water discharge pipe 120 is formed along the inner circumference at the upper side of the filtration tank 100, so that the backwash water discharge pipe 120 can be formed by simply overflowing the overflow guide wall 101. ) Even on the opposite side, the backwash water can be smoothly discharged to the discharge pipe 120 through the overflow waterway 110.
따라서, 상기 월류 유도벽(101)과 월류 유수로(110)의 형성에 의해 역세수(W2)가 여과조(100) 내부에서 역세수 배출관(120)으로 원활하고 신속하게 배출되게 된다.Therefore, by forming the overflow guide wall 101 and the overflow flow path 110, the backwash water W2 is smoothly and quickly discharged from the inside of the filtration tank 100 to the backwash water discharge pipe 120.
