본 고안은 다습성(수분 80%이상)인 폐수 스러지(Sludge)의 건조장치에 관한 것으로, 상세하게는 다습성인 스러지를 건조로와 건조로 중앙에 축설된 고속회전 스크류롤(Screw Roll)을 이용하여 건조와 동시에 잘게 분쇄시킴에 따라 건조효율을 대폭 향상시킨 폐수 스러지 건조장치에 관한 것이다.The present invention relates to a drying device for waste water sludge (moisture more than 80% moisture), and in particular, using a high speed rotating screw roll built in the middle of the drying furnace and drying furnace. The present invention relates to a wastewater sludge drying apparatus that greatly improves the drying efficiency by grinding and grinding finely.

일반적으로 다습성인 폐수 스러지에는 수분이 80%이상 함유되어 부피와 중량이 크고 많이 나가게 되므로 그 처리에 많은 어려움이 있어 처리 기술미비로 좁은 국토의 이곳저곳에 무조건 매립하거나 일반 쓰레기 매립장 등에 그대로 버려져 지하수오염 및 2차 환경공해의 주요인이 외었음은 물론 위탁처리비용도 최근 계속 급격히 상승하여 경제적인 면이 큰 부담이 되었다.In general, the waste water sludge with high humidity contains more than 80% of water, so it is bulky and heavy and outgoing.Therefore, there is a lot of difficulty in its treatment. Not only were the main contributors to pollution and secondary environmental pollution, but also the cost of consignment treatment continued to rise sharply in recent years, causing economic burdens.

따라서 이를 해결하기 위하여 폐수 스러지의 건조 및 소각장치가 계속 연구개발되고 있는 실정이나 이는 대부분이 시스템의 부피가 커지게 되어 설치면적을 많이 차지하게 되었으며, 코스트 또한 높아져 범용화 시킬수 없는 불합리한 문제가 있었고, 시스템의 부피 및 복잡성에 비하여 건조효율은 떨어지는 문제점이 있었다.Therefore, in order to solve this problem, the wastewater sludge drying and incineration equipment has been continuously researched and developed, but most of them have become bulky and occupy a large amount of installation area. There was a problem that the drying efficiency is lower than the volume and complexity.

본 고안은 이같은 제반문제점을 해결하기 위한 것으로 폐수 스러지의 건조 및 분쇄를 한라인에서 동시 처리함에 따라 건조효율은 향상시키고, 장치구조의 간소화로 코스트를 절감하였을 뿐 아니라 설치면적도 줄여 범용화 시킬 수 있도록 한 폐수 스러지의 건조장치를 제공함에 그 목적이 있는 것이다.The present invention is designed to solve these problems and to improve the drying efficiency by simultaneously processing the drying and pulverization of wastewater sludge in one line. It is an object to provide a drying apparatus for a wastewater sludge.

위와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

건조장치(A)를 ON시킨 상태에서 탈수기(미도시됨)에서 방출된 건조 및 분쇄전의 다습성 스러지(31)를 콘베이어라인(10)상에 얹어 투입구(11)를 통해 투입하면 투입된 스러지(31)는 약 30분간 건조로(7)(7') 중앙에 축설되어진 스크류롤(9)(9')의 회전에 의해 압축분쇄되면서 열풍실(2)과 연결되는 건조로(7)(7') 하부의 통기공(6)을 통한 열풍에 의해 건조되어 함수율 20-30%의 수분만을 지닌 건조 및 분쇄된 상태의 스러지(32)로 변하여 스크류롤(9)(9')에 의해 점차 이송되면서 배출구(12)를 통해 외부로 배출된다.When the drying device A is turned on, the wet sludge 31 discharged from the dehydrator (not shown) prior to drying and pulverizing is placed on the conveyor line 10 and introduced through the inlet 11. 31 is a drying furnace 7 connected to the hot air chamber 2 while being compressed and crushed by the rotation of the screw rolls 9, 9 'arranged in the center of the drying furnace 7, 7' for about 30 minutes. 7 ') dried by hot air through the vent hole 6 in the lower part, and turned into a dry and pulverized sludge 32 having only a water content of 20-30% of moisture, by screw rolls 9 and 9'. It is gradually discharged to the outside through the discharge port 12.

이때, 건조로(7)(7')내에서 스크류롤(9)(9')의 회전에 의해 압축, 분쇄, 건조되면서 이송되는 스러지(31)에서 발생되는 악취와 수증기는 버너(3)에서 배출되는 매연과 함께 흡입송풍기(15)의 흡입력으로 덕트(13)(13')상으로 포집되고, 포집된 악취와 수증기 그리고 매연은 덕트(13)(13')의 상단 개방부(14)(14')를 거쳐 송풍관(20)을 통해 1차 집진실(16)내로 집진되면서 분사노즐(28)에 의해 세정되어 차단판(18) 중간의 관통공(19)을 거쳐 2차 집진실(17)로 포집되고, 포집된 분진 및 악취는 분사노즐(28)로 다시 세정되면서 분진은 집진실의 세정수(29) 하부로 가라앉아 유출관(25)을 통해 침전수 탱크(24)로 낙하되는 바, 이때에도 분진 등은 침전수탱크(24)내의 침전수(30) 하부로 가라앉으면서 침전수 탱크(24) 저부에 침전되고 침전수(30)는 다시 분사펌프(26)에 의해 순환파이프(33)내로 계속 순환되어지는 것이고, 악취 및 매연 등은 여과필터(22)를 거쳐 여과되면서 오염물질의 배출을 최소한으로 하여 배기관(23)을 통해 대기로 방출된다.At this time, the odor and water vapor generated in the sludge 31 conveyed while being compressed, pulverized and dried by the rotation of the screw rolls 9 and 9 'in the drying furnaces 7 and 7' are burner 3. The exhaust gas is collected on the ducts 13 and 13 'by the suction force of the suction blower 15, and the collected odor, water vapor, and the smoke are upper openings 14 of the ducts 13 and 13'. The dust collecting chamber 14 is collected into the primary dust collecting chamber 16 through the blower pipe 20, and is cleaned by the spray nozzle 28, and passes through the through hole 19 in the middle of the blocking plate 18. 17) and the collected dust and odor are washed again with the spray nozzle 28, and the dust sinks to the lower portion of the washing water 29 in the dust collecting chamber and falls to the sedimentation tank 24 through the outlet pipe 25. In this case, the dust and the like settles to the bottom of the sedimentation tank 24 while sinking to the lower part of the sedimentation water 30 in the sedimentation tank 24 and the sedimentation water 30 is circulated by the injection pump 26 again. pipe( 33 is continuously circulated, and odors, soot and the like are filtered through the filter filter 22 and are discharged to the atmosphere through the exhaust pipe 23 with a minimum discharge of pollutants.

이상과 같은 본 고안은 폐수 스러지를 분쇄, 이송시키는 고속회전 스크류롤을 건조로 중앙에 축설하여 하나의 라인에서 분쇄와 건조 및 이송을 동시에 행함으로써 건조속도가 빨라 이에 따른 건조효율이 높아지는 것이며, 압축분쇄식으로 각종 스러지를 몇 분의 일로 감량화 시킬수 있어 그 처리가 간편하여지는 등 다수의 괄목할 만한 효과가 있는 것이다.The present invention as described above is to build a high-speed rotating screw roll for crushing and transporting wastewater sludge in the center of the drying furnace to simultaneously perform grinding, drying and conveying in one line, thereby increasing the drying efficiency and thus the compression. It is possible to reduce various sludges by a few minutes by pulverization type, so that the treatment becomes simple and there are many remarkable effects.
