디스크건조장치 및 이를 이용한 건조처리공정{Drying system of disk and Drying treatment processes using the system}Drying system of disk and Drying treatment processes using the system

본 발명은 디스크건조장치 및 이를 이용한 건조처리공정에 관한 것으로서, 이를 보다 상세히 설명하면 건조기 내측의 샤프트와 디스크 내부에 순환되는 열매체(스팀, 열매유, 온수 등)에 의해서 건조기로 투입되는 탈수슬러지를 간접적으로 가열 건조시켜서 함수율(含水率)을 낮춘 건조슬러지로 배출시켜 재활용 및 건조 상태로 폐기하기 위한 디스크건조장치 및 이를 이용한 건조처리공정에 관한 것이다.
The present invention relates to a disk drying apparatus and a drying treatment process using the same, which will be described in more detail. The dehydration sludge introduced into a dryer by a shaft inside the dryer and a heat medium (steam, fruit oil, hot water, etc.) circulated inside the disk is described. Disc drying apparatus and a drying treatment process using the same for discharging to a dry sludge to lower the moisture content (含水 率) by indirect heat drying to recycle and dry.

통상적으로 사료, 어분, 파인 세라믹, 다양한 화학제품 및 하수처리 후의 각종 슬러지 등(이하 "슬러지"라고 총칭함)은 도 1에서와 같이 함수율이 높은 상태에서 슬러지반입조(120)로 반입 후 탈취제 등을 투입해서 함수율을 일부 낮춘 탈수슬러지 상태에서 종래 슬러지건조기(110)에 투입하여 함수율을 10~20%정도까지 건조시킨 건조슬러지를 하부에 형성된 배출구(113)로 배출시키되, 건조슬러지 일부를 제1순환컨베이어(130) 및 제2순환컨베이어(140)를 거쳐서 슬러지건조기(110)로 재순환시키고, 나머지 건조슬러지는 제2순환컨베이어 단부(140)에 설치된 배출댐퍼(150)를 통해서 배출컨베이어(160)로 배출 후 배출컨베이어(160)를 통해서 건조슬러지저장조(170)로 이송시켜 재활용 및 건조 상태로 폐기토록 한 건조처리공정을 갖는 슬러지건조설비(100)가 보편적으로 사용되고 있는 실정이다.Typically, feed, fish meal, fine ceramics, various chemicals and various sludges after the sewage treatment (hereinafter collectively referred to as "sludge") are loaded into the sludge loading tank 120 at a high water content as shown in FIG. In the dehydration sludge state in which the water content is partially lowered by adding to the conventional sludge dryer 110 to discharge the dry sludge dried at a water content of about 10 to 20% to the discharge port 113 formed at the bottom, the first part of the dry sludge The recycle conveyor 130 is recycled to the sludge dryer 110 via the circulation conveyor 130 and the second circulation conveyor 140, and the remaining dry sludge is discharged through the discharge damper 150 installed at the end of the second circulation conveyor 140. After the discharge into the sludge drying facility 100 having a drying treatment process to be transported to the dry sludge storage tank 170 through the discharge conveyor 160 to be recycled and discarded in a dry state. It is used.

상기한 종래 슬러지건조설비(100)에서는 탈수슬러지와 슬러지건조기(110)를 거쳐서 일부가 재순환되는 건조슬러지를 슬러지건조기(110)에 각각 별도로 형성된 슬러지투입구(110a)(110b)를 통해서 내부로 개별 투입한 후 슬러지건조기(110) 내부에서 혼합시키면서 샤프트(111)와 디스크(112) 내부에서 순환되는 열매체로 간접 가열하여 건조시키고 있었으나, 가온 상태의 슬러지건조기(110) 내부에서 함수율이 80%정도로 높은 탈수슬러지와 함수율이 10~20%정도로 낮은 재순환되는 건조슬러지가 혼합될 시 탈수슬러지와 건조슬러지 각각의 수분 함량이 변화됨에 따라 점성이 높아져서 슬러지건조기(110) 내부에서 슬러지가 덩어리지거나 디스크(112)나 슬러지건조기(110) 내벽에 달라붙어서 고착화되므로 건조효율이 급격하게 떨어지거나 샤프트(111)와 디스크(112)에 부하가 걸려서 슬러지건조기(110)에 고장이 발생하는 원인이 되었으며, 건조슬러지가 제2순환컨베이어(140) 단부의 배출댐퍼(150)에서 배출댐퍼(150)의 레벨 조절에 의해서 재순환되는 양(量) 및 배출량이 조절되므로 반드시 배출댐퍼(150)를 설치해야 하며, 슬러지건조기(110) 내부의 슬러지 양을 측정하여 항상 일정량으로 조절하기 위해서 슬러지건조기(110) 하부에 고가의 장치(180)를 설치해야 함으로써 시스템의 컨트롤이 난해하고, 설비비가 앙등하는 등 여러 문제점을 가지고 있었던 것이다.
In the conventional sludge drying equipment 100, the sludge inlets 110a and 110b, which are separately formed in the sludge dryer 110, are partially recycled to the sludge dryer 110 through the dewatered sludge and the sludge dryer 110, respectively. Thereafter, the mixture was mixed inside the sludge dryer 110 and dried by indirect heating with a heat medium circulated in the shaft 111 and the disk 112, but the water content of the sludge dryer 110 in the heated state was about 80%. When the sludge and the recycled sludge having a low water content of 10 to 20% are mixed, the viscosity increases as the moisture content of the dewatered sludge and the dried sludge changes, so that the sludge agglomerates inside the sludge dryer 110 or the disk 112 or As the sludge dryer 110 adheres to the inner wall and is fixed, the drying efficiency is drastically decreased or the load is applied to the shaft 111 and the disk 112. The sludge dryer 110 caused a failure, and the amount of dry sludge recycled by adjusting the level of the discharge damper 150 in the discharge damper 150 at the end of the second circulation conveyor 140. And the discharge is controlled, so the discharge damper 150 must be installed, and the expensive device 180 must be installed below the sludge dryer 110 in order to measure the amount of sludge inside the sludge dryer 110 and always adjust it to a predetermined amount. As a result, the system was difficult to control and equipment costs were rising.

A separate mixer is provided, wherein the sludge mixer is radially installed so that a pair of mixing shafts alternately formed so as not to overlap each other when the paddle rotates is rotated by a motor in the sludge mixer. After the sludge is dried in the inside of the dryer, the discharge side end of the dryer is discharged and a side discharge port is formed along with the lower discharge port so that the sludge is filled to the side discharge port inside the dryer and overflows naturally when the amount of sludge exceeds the set amount (overflow) to be discharged, but to the outside of the side outlet When the handle is operated, a sliding plate slides up and down by a screw to install the opening and closing plate to open and close the side outlet, and a first circulation conveyor is installed at the lower portion of the lower outlet of the dryer to recirculate the discharged dry sludge.

상술한 과제 해결을 위한 구체적인 수단에 의하면, 건조기에 투입되기 전에 건조기의 투입구에 연통되게 설치된 슬러지혼합기에 의해서 함수율이 높은 탈수슬러지와 함수율이 낮은 건조슬러지가 함수율이 일치되게끔 골고루 혼합된 후 건조기 내부로 균일한 상태의 입자와 일정한 양(量)으로 투입되므로 투입 이전에 혼합된 슬러지가 건조기 내부에서 가열되더라도 덩어리지거나 디스크 및 건조기 내벽에 달라붙지 않아서 건조효율을 월등하게 향상시킬 수 있고, 더불어 디스크 및 샤프트의 회전 시 부하를 줄여 고장 발생률을 현저히 줄일 수 있으며, 슬러지배출구를 하부배출구와 측면배출구의 2개소로 설치하므로 슬러지의 재순환 양을 조절하기가 용이하며, 종래 제2순환컨베이어의 단부에 설치되어 배출컨베이어로 건조슬러지를 배출하던 배출댐퍼와 건조기 내부의 슬러지 양을 측정하기 위한 고가의 장치를 필요로 하지 않으므로 설비비를 대폭 줄일 수 있는 등 그 기대되는 효과가 다대한 발명이다.
According to the specific means for solving the above problems, the high-density dehydrated sludge and the low-moisture dry sludge are evenly mixed so that the moisture content is matched by a sludge mixer installed in communication with the inlet of the dryer before being put into the dryer. Since the sludge mixed before the addition is heated inside the dryer, it does not clump or stick to the disk and the inner wall of the dryer, so that the drying efficiency can be improved. It is possible to significantly reduce the failure rate by reducing the load when the shaft rotates, and it is easy to adjust the recirculation amount of the sludge because the sludge outlet is installed in two places, the lower outlet and the side outlet, and is installed at the end of the conventional second circulation conveyor. Discharge dam that discharged dry sludge with discharge conveyor And does not require expensive apparatus for measuring the amount of sludge within the dryer for the invention is that the expected effects, etc. that can greatly reduce the equipment cost.

After the pre-mixing step of evenly mixing in the sludge mixer (5), the dehydration sludge with a high moisture content and the dry sludge with a low moisture content is passed through the pre-mixing step The mixture is mixed evenly so that the rate is about 30 to 50%, and the particles are uniformly introduced into the dryer 2 through the inlet 2a of the dryer 2 and mixed in a predetermined amount. Even though the sludge is heated inside the dryer 2, it does not clump or stick to the inner wall of the disk 4 and the dryer 2, so that the drying efficiency can be significantly improved, and the load at the time of rotation of the shaft 3 and the disk 4 This can significantly reduce the failure rate.

상기 사전혼합단계를 거쳐서 건조기(2)로 투입된 혼합슬러지는 건조기(2) 내측에 설치된 샤프트(3) 및 디스크(4) 내부에서 순환되는 열매체에 의해 간접 가열되어 건조되는 건조단계를 거치고, 건조단계에서는 건조기(2) 내부에서 함수율을 10~20%정도까지 건조시킨 건조슬러지로 배출이 이루어지되, 건조기(2) 내부에 함수율이 상대적으로 높아 건조기(2) 내부에서 건조 및 이송되면서 하부에 위치하는 하부슬러지는 건조기(2)에 하향되게 형성된 하부배출구(8)를 통해 배출이 이루어지는 하부배출단계를 거치게 되며, 건조기(2) 내부에 함수율이 상대적으로 낮아 건조기(2) 내부에서 건조 및 이송되면서 상부에 위치하는 상부슬러지는 건조기(2)의 측면에 측방으로 형성된 측면배출구(9)를 통해 측면 배출이 이루어지는 측면배출단계를 거치게 되며, 상기 하부배출단계에서 하부배출구(8)로 배출되는 건조슬러지가 제1순환컨베이어(15)와 제2순환컨베이어(16)를 통해서 슬러지혼합기(5)의 투입구(5a)로 재순환되는 재순환단계를 거치며, 상기 측면배출단계에서 측면배출구(9)로 배출되는 건조슬러지가 배출컨베이어(14)에 의해서 건조슬러지저장조(30)로 이송이 되는 배출이송단계를 거치며, 상기 건조슬러지저장조(30)로 이송된 건조슬러지는 재활용되거나 건조 상태로 폐기처분되며, 상술한 바와 같은 각각의 공정을 통해서 전체적으로 슬러지건조공정이 이루어지는 것이며, 이때 본 발명에서는 상기와 같이 슬러지배출구를 하부배출구(8)와 측면배출구(9)의 2개소로 설치하므로 슬러지의 재순환 양을 조절하기가 용이하며, 종래 기술의 제2순환컨베이어(140)의 단부에 설치되어 배출컨베이어(160)로 건조슬러지를 배출하던 배출댐퍼(150)를 필요로 하지 않으며, 본 발명의 측면배출구(9)에 의해서 건조기(2) 내부에 슬러지가 측면배출구(9)까지 충진되어 설정된 양보다 더 이상 슬러지의 양이 초과되면 자연적으로 오버플로우되게 구성하므로 종래 기술의 슬러지건조기(110) 내부의 슬러지 양을 측정하여 항상 일정량으로 조절하기 위해서 슬러지건조기(110) 하부에 설치되던 고가의 장치(180)를 설치할 필요가 없어서 설비비를 대폭 줄일 수 있는 것이다.
