SLS-MDW(Mechanical Dewatering Filter Press System)

 

Filter Press Dewatering System

  • Filter press is the solid liquid separation system.
  • 1st process is that the sludges are fed into in the chamber of filter plate by using the high pressure pump.
  • 2nd process is the squeezing, de-caking and washing.
  • Finally, dewatered cake is produced.

 

Common Specification

  • Reduction of operation cost by automatic unmanned system.
  • Squeezing dewatering by using the high pressure pump.
  • Possibility to product the low water content sludge by secondary squeezing pressure(7∼20kgf/cm2).
  • De-caking by the automatic filter plate shifter.
  • High pr. washing equipment of filter media.
  • - to protect the fouling and increase the life cycle of filter media.
  • Use the filter plate with anti-corrosion and anti-friction.
  • Frame body to use the SUS lining with rolled steel.
  • Reduction of installation cost with applying the diverse standard.
  • Low management expenses due to without system trouble.
  • Protect the overload of system by using the torque guard.
  • Little influence of sludge properties.
  • Low solid content within Filtrate.
  • Application
  • - Water works and waste sludge
    - Dye and pigment process sludge
    - Livestock wastewater sludge
    - Food process sludge
    - Other process sludge

열탈수시스템

SLS-MTDW(Thermal Dewatering System)

탈수원리

  • 열원으로부터 케이크 층에 전도열 인가
  • 탈수 케이크 층내 모세관에 부착되어 있는 잔류 여액을 내부 증발압력으로 배출
  • 외부가압력(공급압+압착압) + 내부가압력(여액증발압)
  • 케이크층에 열인가는 케이크의 비저힝성 감소시켜 탈수율을 향상시킴

 

장치특성

  • Filtration Velocity(Capacity)는 원 슬러지의 유기물 함량과 관련이 있음
  • Heat Source는 Steam와 Hot Water 모두 이용 가능
  • 여액을 Hot Water로 재이용 가능
  • 동절기 슬러지(유기물 함량 : 40 wt%)의 경우에도 함수율이 50wt%인 저함수율 탈수 케이크 생산가능
  • 케이크의 최고 상승온도 : 70℃
  • 케이크 박리 상태 양호
  • 적용범위
  • - 상·하수 슬러지
    - 염료/안료 공정 슬러지
    - 축산폐수 슬러지
    - 기타 공정 슬러지

주요장치 구성 및 특성

Construction and Characterization of Main Devices

NO DESCRIPTION CHARACTERIZATION APPEARANCE
1 PLATE SHIFTING SYSTEM
(여판이송장치)
여과판을 이송하기 위한 이송블록이 모터에 의한 체인 정역구동으로 고장의 위험이 없으며, 과부하 검출장치가 부착되어 여과판 손잡이 파손 및 협착사고를 방지함으로써 높은 안전성을 보유하고 있습니다.
또한 순차방식에 의한 여과판의 이송은 1장부터 5장까지 탈수기의 사양에 따라 다양하게 선택이 가능합니다.
2 CLOTH VIBRATOR
(여포진동장치)
여과포를 여과판 상부에 장착된 여포걸이장치에 설치하여 공기압에 의한 햄머의 수직력과 스프링에 의한 복원력에 의해 여과포를 10회 정도 진동시킴으로써 점성이 높은 케이크도 완전박리가 가능하여 여과포의 탈수효율을 극대화합니다.
3 CLOTH WASHING UNIT
(여포세정장치)
특수체인에 의한 수직 2단축 삽입식 구동으로 낮은 층고에서도 여과포 의 세정이 가능하며, 세정시 비산되는 오염원으로 부터 안전한 밀폐형 구조를 채택하고 있습니다.
또한 과부하 검출장치가 부착되어 여과포의 손상을 방지함으로써 높은 운전효율을 유지합니다.
