Description

밀도 조절형 섬유상 여과장치{Density-adjustable Fibrous Filter}Density-adjustable Fibrous Filter

본 고안은 섬유사 다발이 다수 삽입된 여과장치로 통과하는 원수를 여과할 수 있도록 하는 밀도 조절형 섬유상 여과장치에 관한 것으로,The present invention relates to a density-controlled fibrous filtration device that can filter the raw water passing through the filter device is inserted into a plurality of fiber yarns,

특히, 원수가 유입되고 배출되는 원통형 여과장치에 섬유다발을 다수개 삽입하고, 섬유사의 공극을 좁게한 상태로 부유물질을 포함한 원수를 통과시켜 섬유사의 좁은 공극 사이로 부유물질을 걸러 여과시킬 수 있을 뿐만 아니라, 역세 수압으로 섬유사 사이에 낀 여과물질을 쉽게 세척할 수 있도록 하는 섬유상 여과장치에 관한 것이다.In particular, a plurality of fiber bundles may be inserted into a cylindrical filtration device through which raw water is introduced and discharged, and the raw material including the suspended matter may be passed through the narrowed pores of the fiber yarn to filter the suspended matter through the narrow pores of the fiber yarn. Rather, the present invention relates to a fibrous filtration device that makes it easy to wash the filtration material caught between the fiber yarns with backwash water pressure.

일반적으로 여과장치의 운전은 여과와 역세척으로 이루어진다. 여과란 넓은 의미에서 유체 속의 현탁 고체와 액체입자를 분리시키는 조작을 의미하며, 좁은 의미에서는 물과 같은 액체중의 고체입자를 분리하기 위한 조작으로서, 고체입자를 포함한 액체 혼합물을 다공성 여과소재를 지나게 하여 고체는 여과소재의 표면이나 내부에 퇴적시키고, 액체는 투과시켜 양자를 분리시키는 기계조작을 의미한다.In general, the operation of the filtration system consists of filtration and backwashing. Filtration refers to the operation of separating suspended solids and liquid particles in a fluid in a broad sense, and to separate solid particles in a liquid such as water in a narrow sense. A liquid mixture containing solid particles is passed through a porous filter material. This means that the solid is deposited on the surface or inside of the filter material, and the liquid is permeated to separate the two.

상기와 같은 여과와 역세척으로 이루어지는 종래의 여과장치는 여과해야 할 원수가 통과하는 이송경로에 여과장치를 설치하여 원수가 여과장치를 통과하면서 오염물질을 걸러내고, 일정시간 여과장치를 사용하면 여과장치를 교환하거나 여과수를 역으로 공급하여 여과장치를 세척하는 방법이 사용되고 있었다.In the conventional filtration device consisting of the above filtration and backwashing, the filtration device is installed in the transport path through which the raw water to be filtered passes to filter the contaminants while the raw water passes through the filtration device. A method of cleaning the filtration device by replacing the device or by feeding the filtrate back was used.

그러나 종래의 상기와 같은 여과장치는 여과장치의 내부를 여과소재로 가득 채워서 여과소재가 구비된 여과장치의 내부 밀도를 높인 상태에서 원수가 여과장치를 통과할 때 여과소재의 밀도에 의해 원수 속의 오염물질을 걸러낼 수 있도록 하고 있었으나, 이러한 여과장치는 여과장치 내부전체를 여과소재로 가득 채움으로서 여과장치 내부의 밀도가 너무 높아지는 문제점이 자주 발생되었다.However, in the conventional filter device as described above, the inside of the filter device is filled with the filter material to increase the internal density of the filter device provided with the filter material, and when raw water passes through the filter device, the contamination of the raw water by the density of the filter material. Although it was possible to filter the material, such a filtration device is often filled with the filter material as a whole, the problem that the density inside the filtration device becomes too high.

또한 상기와 같이 여과장치의 내부 밀도가 너무 높으면 원수의 여과속도가 너무 느려지게 될 뿐만 아니라, 오염물질이 걸러진 여과소재를 역으로 세척하기가 어려워지므로 여과장치를 역세한 후에도 오염물질이 여과수와 함께 생산되므로 여과장치를 자주 교환해야 하는 문제점이 발생되었다.In addition, if the internal density of the filtration device is too high as described above, the filtration speed of the raw water becomes too slow, and it becomes difficult to reversely filter the filtered filter material. As a result, there is a problem in that the filtration device needs to be replaced frequently.

따라서, 본 고안의 목적은 여과장치 내부에 여러 개의 섬유다발을 구비하면서 그 섬유다발의 상측으로 공간이 구비되도록 함으로서 원수를 여과할 때는 섬유다발의 밀도가 높아져 충분한 여과효과를 제공할 뿐만 아니라, 섬유다발을 역세시에는 섬유다발의 밀도가 낮아지면서 섬유다발 사이의 오염물질을 완벽하게 세척하여 제거할 수 있도록 한 밀도조절형 섬유상 여과장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a space to the upper side of the fiber bundle while having a plurality of fiber bundles inside the filtering device to increase the density of the fiber bundle when filtering the raw water not only provide sufficient filtration effect, but also the fiber When the bundle is backwashed, the density of the fiber bundle is lowered, thereby providing a density-controlled fibrous filtration device for completely washing and removing contaminants between the fiber bundles.

이러한 본 고안의 목적은 여과장치 내부에 다수의 섬유다발을 삽입하고, 그 섬유다발의 상측과 하측은 각각 묶어서 여과장치의 상부다공판과 하부다공판에 고정하되 섬유다발의 하단은 하부다공판에 밀착되게 고정하고, 섬유다발의 상단은 상부연결끈으로 상부다공판에 연결 고정함으로서 이룰 수 있다.The purpose of the present invention is to insert a plurality of fiber bundles inside the filtering device, the upper and lower sides of the fiber bundle is tied to each of the upper and lower perforated plate of the filtering device fixed to the lower perforated plate Fixing closely, the upper end of the fiber bundle can be achieved by connecting to the upper perforated plate with an upper connecting strap.

이하, 본 고안의 바람직한 실시예를 첨부 도면에 의하여 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

상단홀(101)로 원수가 삽입되어 다수의 섬유다발(11)을 통과하면서 여과된 후, 하단홀(102)을 통해 여과된 처리수가 배출되도록 여과장치(1)를 구성한다.After the raw water is inserted into the upper hole 101 and filtered while passing through the plurality of fiber bundles 11, the filtering device 1 is configured to discharge the treated water filtered through the lower hole 102.

이때 상기 여과장치(1) 내부에 다수의 섬유다발(11)을 삽입하고, 그 섬유다발(11)의 상측과 하측은 각각 묶어서 여과장치(1)의 상부다공판(12)과하부다공판(13)에 고정하되 섬유다발(11)의 하단은 하부다공판(13)에 밀착되게 고정하고, 섬유다발(11)의 상단은 상부연결끈(111)으로 상부다공판(12)에 연결 고정하여 섬유다발(11)의 상단이 상부다공판(12)에서 일정한 간격을 유지하도록 한다.In this case, a plurality of fiber bundles 11 are inserted into the filtration device 1, and the upper and lower sides of the fiber bundles 11 are bundled, respectively, so that the upper porous plate 12 and the lower porous plate 13 of the filtering device 1 are connected. The bottom of the fiber bundle 11 is fixed in close contact with the lower perforated plate 13, and the upper end of the fiber bundle 11 is connected to the upper porous plate 12 with the upper connecting string 111 to fix the fiber. The upper end of the bundle 11 to maintain a constant interval in the upper perforated plate 12.

상기와 같이 구성된 여과장치(10)는 그 상단홀(101)을 원수공급펌프(22)와 원수공급밸브(23)가 구비된 원수공급관(20)으로 원수수조(21)에 연결함과 동시에 그 상단홀(101)은 드레인벨브(61)가 구비된 배수관(60)도 함께 연결한다.The filtration device 10 configured as described above is connected to the raw water tank 21 by the raw water supply pipe 20 provided with the upper water supply pump 22 and the raw water supply valve 23. Top hole 101 is also connected to the drain pipe 60 is provided with a drain valve (61).

또한 상기 여과장치(10)의 하단홀(102)은 처리수밸브(31)가 구비된 처리수관(30)으로 처리수수조(32)에 연결하고, 역세펌프(41)와 역세밸브(42)가 구비된 역세관(40)으로 상기 하단홀(102)과 처리수수조(32)를 다시 연결함과 동시에 에어펌프(51)와 에어공급밸브(52)가 구비된 에어공급관(50)을 상기 역세관(40)에 연결하여 처리수와 에어로 여과장치(10)의 내부를 세척할 수 있도록 한다.In addition, the lower hole 102 of the filtration device 10 is connected to the treatment water tank 32 by the treatment water pipe 30 having the treatment water valve 31, and the backwash pump 41 and the backwash valve 42. Reconnect the lower hole 102 and the treated water tank 32 to the back washing pipe 40 provided with the air pump 51 and the air supply pipe 50 provided with the air supply valve 52. It is connected to the backwashing pipe 40 so as to wash the inside of the treated water and the aero filtration device 10.

이와 같이 구성된 본 고안은 여과장치(10)의 상단홀(101)로 원수를 공급하면 원수는 상부다공판(12)의 무수히 많은 홀(121)을 통해 하측으로 이동하면서 섬유다발(11)을 통과하게 되므로 섬유다발(11)에서 여과가 된 후, 그 처리수는 여과장치(10)의 하부다공판(13)에 형성된 무수히 많은 홀(131)과 여과장치(10)의 하단홀(102)을 통해 배출되는 것이다.When the raw water is supplied to the upper hole 101 of the filtering device 10, the raw water passes through the fiber bundle 11 while moving downward through the myriad holes 121 of the upper porous plate 12. After the filtration in the fiber bundle 11, the treated water is a myriad of holes 131 formed in the lower porous plate 13 of the filtration device 10 and the lower hole 102 of the filtration device 10 Will be discharged through.

즉, 상기와 같이 여과작용을 하는 본 고안을 도 1과 도 4에 도시한 사용상태 회로도에 의하면, 먼저 상기 회로도에 구비된 모든 펌프(22)(41)(51)와 모든 밸브(23)(31)(42)(52)(61) 및 차압계(14)는 콘트롤부(70)에 설정된 프로그램에 의해 제어된다.That is, according to the use state circuit diagram shown in Figs. 1 and 4 of the present invention that performs the filtration as described above, first, all the pumps 22, 41, 51 and all the valves 23 ( 31, 42, 52, 61 and the differential pressure gauge 14 are controlled by a program set in the controller 70.

상기와 같이 콘트롤부(70)에 의해 제어되는 본 고안의 도 1 및 도 2와 같은 여과과정을 살펴보면, 먼저 원수공급밸브(23)를 열고, 원수수조(21)에 담긴 원수를 원수공급펌프(22)로 펌핑하여 원수공급관(20)을 따라 이동시키면 원수는 여과장치(10)의 상단홀(101)로 유입된다.Looking at the filtration process as shown in Figures 1 and 2 of the present invention controlled by the control unit 70 as described above, first open the raw water supply valve 23, the raw water contained in the raw water tank 21 to the raw water supply pump ( By pumping 22 and moving along the raw water supply pipe 20, the raw water is introduced into the upper hole 101 of the filtering device 10.

상기 여과장치(10)로 유입된 원수는 상부다공판(12)에 형성된 무수히 많은 홀(121)을 통하여 여과장치(10) 내부의 섬유다발(11)을 통과하게 된다.The raw water introduced into the filtering device 10 passes through the fiber bundle 11 inside the filtering device 10 through a myriad of holes 121 formed in the upper porous plate 12.

이때 상단과 하단이 고정부재(112)(113)에 의해 상부다공판(12)과 하부다공판(13)에 고정된 섬유다발(11)은 상단이 상부연결끈(111)에 의해 상부다공판(12)으로부터 상부연결끈(111) 길이만큼 늘어져있는 상태가 되므로 여과장치(10) 내의 섬유다발(11) 밀도는 그만큼 높은 상태가 되고, 이로 인하여 섬유다발(11)을 통과하는 원수에서 오염물질이 여과되는 것이다.At this time, the upper and lower ends of the fiber bundle 11 fixed to the upper perforated plate 12 and the lower porous plate 13 by the fixing member 112, 113, the upper perforated plate by the upper connecting string 111 Since the length of the upper connecting string 111 extends from 12, the density of the fiber bundle 11 in the filtration device 10 becomes so high that the contaminants in the raw water passing through the fiber bundle 11 are increased. This is to be filtered.

상기와 같이 섬유다발(11)을 통과하면서 여과된 처리수는 하부다공판(13)의 홀(131)을 통해 섬유다발(11)에서 빠져나가고 이어서 여과장치(10)의 하단홀(102)을 통해 여과장치(10)에서 배출된다.The treated water filtered while passing through the fiber bundle 11 as described above exits from the fiber bundle 11 through the hole 131 of the lower porous plate 13 and then opens the lower hole 102 of the filtration device 10. It is discharged from the filtration device 10 through.

상기와 같이 여과장치(10)에서 여과된 상태로 배출된 처리수는 역세밸브(42)와 에어공급밸브(52)는 닫히고 처리수밸브(31)는 열린상태이므로 처리수밸브(310가 구비된 처리수관(30)을 따라 이송되어 처리수수조(32)에 담겨지게 된다.As the treatment water discharged in the filtered state in the filtration device 10 as described above, the backwash valve 42 and the air supply valve 52 are closed, and the treatment water valve 31 is open, so that the treatment water valve 310 is provided. It is transferred along the treatment water pipe 30 and is contained in the treatment water tank 32.

또한 상기 여과작용이 지속적으로 진행됨에 따라 여과장치(10) 내의 섬유다발(11)에는 원수에서 여과된 오염물질이 쌓이게 되고, 이러한 섬유다발(11)에 쌓이는 오염물질은 여과성능을 저하시키므로 공급되는 원수를 원활하게 여과처리하지 못하게 되고, 이러한 처리성능 저하는 여과장치(10) 상측의 원수공급관(20)에 부하가 걸리는 현상으로 나타난다.In addition, as the filtration continues, the fiber bundle 11 in the filtration apparatus 10 accumulates contaminants filtered from raw water, and the pollutants accumulated in the fiber bundle 11 are deteriorated in filtration performance. The raw water cannot be filtered smoothly, and such a decrease in processing performance appears to be a load on the raw water supply pipe 20 above the filtration device 10.

이때 상기와 같이 원수공급관(20)에 부하가 걸리면 여과장치(10)의 상측 원수공급관(20)과 여과장치(10) 하측의 처리수관(30)에서 압력의 차이를 체크하고 있는 차압계(14)에 감지되고, 그 차압계(14)에 감지된 압력의 차이가 콘트롤부(70)에 설정된 압력의 차이보다 커지면 콘트롤부(70)는 도 4 및 도 5에 도시된 바와 같이 원수공급펌프(22)를 정지시키고, 원수공급밸브(23)와 처리수밸브(31)를 닫음과 동시에 역세밸브(42)와 에어공급밸브(52) 및 드레인밸브(61)를 열고 역세펌프(41)와 에어펌프(51)를 가동시킨다.In this case, when the load is applied to the raw water supply pipe 20 as described above, the differential pressure gauge 14 checking the difference in pressure between the upper raw water supply pipe 20 of the filtration device 10 and the treated water pipe 30 below the filtration device 10. When the difference in pressure sensed by the differential pressure gauge 14 is greater than the difference in pressure set in the control unit 70, the control unit 70 as shown in Figs. 4 and 5 the raw water supply pump 22 The water supply valve 23 and the treated water valve 31 are closed, and the backwash valve 42, the air supply valve 52, and the drain valve 61 are opened, and the backwash pump 41 and the air pump ( 51).

상기와 같이 가동된 역세펌프(41)는 처리수수조(32)에 담긴 처리수를 펌핑하여 역세관(40)을 따라 여과장치(10)의 하단홀(102)로 공급하고, 가동된 에어펌프(51)는 압축공기를 에어공급관(50)을 따라 여과장치(10)의 하단홀(102)로 공급하여 여과장치(10) 내부의 섬유다발(11)을 세척한다.The backwash pump 41 operated as described above pumps the treated water contained in the treated water tank 32 and supplies the treated backwater to the lower hole 102 of the filtration device 10 along the backwashed pipe 40 and the operated air pump. 51 supplies compressed air to the lower hole 102 of the filtering device 10 along the air supply pipe 50 to wash the fiber bundle 11 inside the filtering device 10.

즉, 많은 오염물질을 여과하여 섬유다발(11) 내에 오염물질이 많이 축적됨에 따라 역세펌프(41)와 에어펌프(51)가 가동되면 역세펌프(41)는 여과처리된 처리수를 펌핑하여 역세관(40)을 따라 압송하고, 에어펌프(51)는 공기를 압축하여 에어공급관(50)을 따라 펌핑하게 되는 것이다.That is, when the backwash pump 41 and the air pump 51 operate as the pollutants are accumulated in the fiber bundle 11 by filtering a lot of pollutants, the backwash pump 41 pumps the treated water to reverse the process. Pumped along the tubule 40, the air pump 51 is to compress the air is pumped along the air supply pipe (50).

상기와 같이 펌핑된 처리수와 공기는 역세밸브(42)와 에어공급밸브(52)를 지난 후 여과장치(10)의 하단홀(102)을 통해 여과장치(10) 내로 유입되어여과장치(10)의 하부다공판(13)에 형성된 무수히 많은 홀(131)을 통해 섬유다발(11) 사이로 공급된다.The treated water and air pumped as described above are introduced into the filtration device 10 through the lower hole 102 of the filtration device 10 after passing through the backwash valve 42 and the air supply valve 52. It is supplied between the fiber bundle 11 through a myriad of holes 131 formed in the lower porous plate 13 of the ().

이때 섬유다발(11)은 여과작용을 할 때 자중과 원수가 공급되는 압력에 의하해 하측으로 처져 높은 밀도를 유지하고 있는 상태로 있다가 여과장치(10)의 하측으로부터 공급된 처리수와 압축공기의 압력으로 인하여 상측으로 펴지면서 늘어게 된다.At this time, the fiber bundle 11 sags downward due to its own weight and pressure supplied from the raw water to maintain high density, and the treated water and compressed air supplied from the lower side of the filtering device 10 are filtered. Due to the pressure of the upwardly stretched upwards.

따라서 역세펌프(41)에 의해 공급되는 처리수와 에어펌프(51)에 의해 공급되는 압축공기가 섬유다발(11)의 밀도는 낮춘 상태로 지나면서 섬유다발(11)에 묻어있는 오염물질을 세척하여 상부다공판(12)의 홀(121)과 여과장치(10)의 상단홀(101)을 통해 여과장치(10)에서 배출하고, 여과장치(10)의 상단홀(101)에서 배출된 세척수는 드레인밸브(61)가 열려있는 배수관을 따라 배출되는 것이다.Therefore, while the treated water supplied by the backwash pump 41 and the compressed air supplied by the air pump 51 pass while the density of the fiber bundle 11 is lowered, the contaminants buried in the fiber bundle 11 are washed. And discharged from the filtration device 10 through the hole 121 of the upper porous plate 12 and the top hole 101 of the filtration device 10, the washing water discharged from the top hole 101 of the filtration device 10 The drain valve 61 is discharged along the open drain pipe.

상기와 같은 섬유다발(11) 세척작업은 콘트롤부(70)에 설정해 놓은 시간만큼 작업이 이루어지도록 하는 것이 바람직하며, 섬유다발(11)에 묻어잇는 오염물질을 세척한 후에는 역세펌프(41)와 에어펌프(51)를 정지시키고, 역세밸브(42)와 에어공급밸브(52) 및 드레인밸브(61)를 닫음과 동시에 원수공급밸브(23)와 처리수밸브(31)를 열고 원수공급펌프(22)를 가동시키면 세척된 섬유다발(11)이 다시 자중과 원수 유입압력에 의해 여과장치(10) 하측으로 처진상태로 높은 밀도를 갖게 되므로 원수의 여과작업을 원활하게 할 수 있게 되는 것이다.The fiber bundle 11 cleaning operation as described above is preferably performed so that the operation is made by the time set in the control unit 70, after washing the contaminants buried in the fiber bundle 11 backwash pump 41 And the air pump 51 is stopped, the backwash valve 42, the air supply valve 52 and the drain valve 61 are closed, and the raw water supply valve 23 and the treated water valve 31 are opened to open the raw water supply pump. When the 22 is operated, the washed fiber bundle 11 again has a high density under the filtration device 10 due to its own weight and raw water inflow pressure, so that the filtration operation of the raw water can be smoothly performed.

한편 도 7은 본 고안의 다른 실시예를 보인 요부 확대단면도로서,On the other hand Figure 7 is an enlarged cross-sectional view of the main portion showing another embodiment of the present invention,

The upper end of the bundle 11 is inserted through the hole 121 of the upper porous plate 12, a plurality of upper connecting straps 111 tied to the upper end, and inserted into the hole 121 of the upper porous plate 12 Collecting the upper connecting string 111 and withdrawing the upper connecting string 111 collected through the upper hole 101 of the filtering device 10 to the outside of the filtering device 10, and then rotating the upper connecting string 11 to the rotating shaft. It is fixed to be wound on the winding member 161 of (16).

이때 상기 회전축(16)은 그 일측에 손으로 돌릴 수 있는 손잡이를 설치하거나 콘트롤부(70)에 의해 제어되는 모터를 설치하여 회전축(16)을 회전시킬 수 있도록 하는 것이 바람직하며, 그 회전축(16)에 구비된 권취부재(161)는 회전축(16)의 회전방향에 따라 상부연결끈(111)을 감거나 풀 수 있도록 풀리 등의 권취부재(161)를 사용하는 것이 바람직하다.At this time, the rotating shaft 16 is preferably installed on the one side that can be rotated by hand or by installing a motor controlled by the control unit 70 to rotate the rotating shaft 16, the rotating shaft 16 Winding member 161 provided in the) it is preferable to use a winding member 161, such as a pulley to wind or unwind the upper connecting string 111 in accordance with the rotation direction of the rotary shaft (16).

상기와 같이 섬유다발(11)의 상단을 묶어서 고정한 상부연결끈(111)을 여과장치(10) 외부의 권취부재(161)에 고정하면 회전축(16)을 회전시켜 상부연결끈(111)을 권취부재(161)에 감거나 풀어주는 정도에 따라 섬유다발(11)이 여과장치(10)에 내에서 처지는 정도를 조절할 수 있게 되는 것이다.When the upper connecting string 111 is fixed to the winding member 161 outside the filtering device 10 by tying and fixing the upper end of the fiber bundle 11 as described above, the rotating shaft 16 is rotated to wind the upper connecting string 111. According to the degree of winding or unwinding the member 161, the fiber bundle 11 is to be able to adjust the degree of sagging within the filtration device (10).

따라서 상기와 같이 섬유다발(11)의 처짐이 조절되면 여과장치(10)의 내부 밀도를 임의대로 조절할 수 있을 뿐만 아니라, 섬유다발(11)에 묻은 오염물질을 세척할 때도 상부연결끈(111)을 권취부재(161)에 감아서 섬유다발(11)을 인위적으로 늘려 밀도를 낮게 조절할 수 있으므로 섬유다발(11)의 세척작업을 더욱 효율적으로 실시할 수 있게 되는 것이다.Therefore, when the deflection of the fiber bundle 11 is adjusted as described above, not only the internal density of the filtering device 10 can be arbitrarily adjusted, but also the upper connection string 111 when washing contaminants on the fiber bundle 11. By winding the winding member 161 to artificially increase the fiber bundle 11, the density can be adjusted low, so that the washing operation of the fiber bundle 11 can be performed more efficiently.
