오탁수 이물질 필터링 및 필터청소 자동화 장치{Stained water foreign matter filtering and filter cleaning automation device}Stained water foreign matter filtering and filter cleaning automation device

본 발명은 준설현장에서 발생하는 오탁수를 정수하고, 오탁수 이물질 필터링 및 필터청소 자동화 장치에 관한 것이다. 보다 상세하게는, 준설토를 처리하는 과정에서 발생되는 오탁수를 유입하여 정수처리하되, 필터부의 전단과 후단의 압력차를 센싱하여 압력차에 따라 필터 내부를 자동청소하고, 오탁수 필터공정과 필터 청소공정이 하나의 통합공정으로 진행되어 정수능력을 극대화하고, 환경기준에 적합한 정수처리가 가능하도록 하는 오탁수 이물질 필터링 및 필터청소 자동화 장치에 관한 것이다.The present invention relates to an apparatus for purifying polluted water generated at a dredging site, filtering impurities in polluted water, and automating filter cleaning. More specifically, the polluted water generated in the process of treating the dredged soil is introduced and purified, but the pressure difference between the front and rear ends of the filter unit is sensed to automatically clean the inside of the filter according to the pressure difference, and the polluted water filter process and filter The present invention relates to an automatic device for filtering polluted water foreign matter and filter cleaning, which maximizes water purifying capacity by performing a cleaning process as an integrated process and enables water treatment suitable for environmental standards.

일반적으로 해안가나 하천의 바닥면에 퇴적된 뻘, 모래, 자갈, 이물질 등의 준설토를 제거하기 위해서는 그래브(grab) 및 디퍼(dipper) 방식과 펌프로 흡입하여 준설작업을 진행하게 되는데, 준설토를 처리하는 과정에서 오탁수가 발생하게 된다.In general, in order to remove dredged soil such as mud, sand, gravel, foreign matter, etc. deposited on the shore or the bottom of a river, dredging is performed by suction with a grab and dipper method and a pump. Contaminated water is generated during the treatment process.

종래의 일반적인 수처리방식은 대용량으로 조성한 투기공간에 순차적으로 오탁수가 침전될 수 있는 침사지 등을 통해 펌핑 또는 덤핑을 하고 상등수를 방류하였으나, 현재에는 준설토 탈수를 통한 자원재활용과 준설오폐수가 환경에 미치는 영향을 최소화하기 위해 각 지역마다 배출 가능한 배출수 기준이 정해져서 기준치를 충족하는 상태에서만 배출수 방류가 허용되고 있다. In the conventional general water treatment method, pumping or dumping was performed through a grit chamber in which polluted water can be precipitated sequentially in a large-capacity dumping space, and the supernatant was discharged. Currently, resource recycling through dredged soil dehydration and environmental impact of dredged wastewater In order to minimize the discharge, dischargeable water standards are set for each region, and discharge water is allowed only when the standards are met.

또한, 준설토의 수분을 제거하여 재활용하기 위한 탈수공정에서도 오탁수가 발생되어 오탁수 또한 배출수 기준에 충족되어야만 방류가 허용된다. In addition, polluted water is generated in the dewatering process for recycling by removing moisture from the dredged soil, and discharge is allowed only when the polluted water meets the discharge water standard.

한편, 펌프 흡입방식의 준설토 처리 방식은 적게는 시간당 200m3, 많게는 5,000m3 이상이 펌핑되는 데 이러한 대용량의 준설수를 실시간으로 정수하여 배출수 기준을 충족하는 수준의 정수능력을 보장하려면 충분한 침전시간을 가질 수 있는 용량의 침전지가 제공되거나 이러한 용량을 제공하는 기계적인 방식의 정수시스템이 필요하게 된다. On the other hand, the dredged soil treatment method of the pump suction method is at least 200m 3 per hour and at most 5,000m 3 or more In order to purify this large amount of dredged water in real time to ensure a level of water purification capacity that meets the discharge water standard, a settling tank with a capacity that can have a sufficient settling time is provided, or a mechanical water purification system that provides this capacity is required. will be needed

그러나, 현실은 충분한 면적의 침전지를 확보하기 어려운 경우가 많아서 적은 설치면적으로 충분한 정수능력을 제공하는 기계적인 방식의 정수 시스템이 유일한 해결책이 된다. However, in reality, it is often difficult to secure a sedimentation pond with a sufficient area, so a mechanical water purification system that provides sufficient water purification capacity with a small installation area is the only solution.

또한, 환경기준을 충족하려면 지역에 따라 최대 5ppm 수준의 배출수를 실시간으로 시간당 최대 5,000m3 이상 정수할 수 있어야 하는 데 일반적으로 사용하는 샌드필터나 카트리지필터는 이러한 대용량을 처리하기 위해 필요한 장비규모가 너무 커서 비효율적이다. In addition, in order to meet environmental standards, it is necessary to be able to purify up to 5,000 m 3 or more of discharged water in real time, depending on the region, up to 5,000 m 3 per hour in real time. The sand filter or cartridge filter that is generally used does not have the equipment scale required to handle such a large amount. Too big and inefficient.

바이패스밸브(170)의 일측면에는 메인필터인 1차필터부(50) 및 2차필터부(60)의 문제발생 시에 대체필터로 마련된 비상필터(미도시)가 구비된다. On one side of the bypass valve 170, an emergency filter (not shown) is provided as an alternative filter when a problem occurs in the primary filter unit 50 and the secondary filter unit 60, which are main filters.

제어부(30)는 세척노즐(100)을 가동시키는 제어신호를 전송하여 구동부(200)로 전송하여 필터 내부를 청소한 이후, 제1 차압센서(70) 및 제2 차압센서(80)의 각 차압값을 재수신하여 기 설정된 임계차압값 이상인 경우 필터 청소가 불완전하게 진행되었다고 판단하고, 유입밸브(180)를 차단시키는 동작신호를 인가하여 유입밸브(180)를 제어하여 필터로 유입되는 통로를 차단시키고, 바이패스밸브(170)를 개방시키는 동작신호를 바이패스밸브(170)에 인가하여 바이패스밸브(170)를 제어한다. The control unit 30 transmits a control signal for operating the washing nozzle 100 to the driving unit 200 to clean the inside of the filter, and then the differential pressures of the first differential pressure sensor 70 and the second differential pressure sensor 80. When the value is re-received and the value is higher than the preset threshold differential pressure value, it is determined that filter cleaning has been incompletely performed, and an operation signal for blocking the inlet valve 180 is applied to control the inlet valve 180 to block the passage leading to the filter. and an operation signal for opening the bypass valve 170 is applied to the bypass valve 170 to control the bypass valve 170.

제어부(30)의 밸브제어부(93)에 의해 유입밸브가 폐쇄되고, 바이패스밸브(170)가 개방되면, 오수유입부(30)로부터 유입된 오탁수는 유입밸브(180)를 통해 메인필터인 1차필터부(50) 및 2차필터부(60)를 통과하지 않고, 바이패스밸브(170)의 일측면에 마련된 비상필터(미도시)를 통과하여 비상필터에 의해 정수처리를 거쳐 정수배출부(140)를 통해 토출된다. When the inlet valve is closed by the valve control unit 93 of the control unit 30 and the bypass valve 170 is opened, the filthy water introduced from the sewage inlet 30 passes through the inlet valve 180 to the main filter. Without passing through the primary filter unit 50 and the secondary filter unit 60, it passes through an emergency filter (not shown) provided on one side of the bypass valve 170, undergoes water treatment by the emergency filter, and discharges purified water. It is discharged through part 140.

이때, 제어부(30)는 바이패스밸브(170)를 개방시키는 동작신호를 바이패스밸브(170)에 인가하면서 필터 내부 및 세척노즐의 작동상태를 점검하라는 알림정보를 사용자의 모바일기기로 전송한다. At this time, the control unit 30 transmits notification information to the user's mobile device to check the operation state of the inside of the filter and the washing nozzle while applying an operation signal for opening the bypass valve 170 to the bypass valve 170 .

또한, 도시되지 않았으나, 오탁수 이물질 필터링 및 필터청소 자동화 장치(1000)는 무선통신으로 스마트기기와 통신하는 무선통신부(미도시)가 구비되고, 상기 무선통신부(미도시)를 통해 전송받은 신호에 의해 오탁수 이물질 필터링 및 필터청소 자동화 장치(1000)를 제어한다.
