Abstract
Description
본 발명은 슬러지 탈수장치에 관한 것으로서, 특히 응고제로 케익화된 슬러지를 스크린컨베이어로 이송시키는 과정에서 압착컨베이어로 압착함과 동시에 진동을 주어 양호한 탈수효율 득하도록 하는 슬러지 탈수장치에 관한 것이다.The present invention relates to a sludge dewatering apparatus, and more particularly, to a sludge dewatering apparatus for compressing and simultaneously vibrating with a pressing conveyor in a process of transferring a sludge caked with a coagulant to a screen conveyor to obtain good dewatering efficiency.
일반적으로 환경오염으로 인한 폐해는 어느나라에 국한 된 것이 아니라 전인류의 생존에 관련된 문제로 대두되어 이를 해결하기 위해 국제 협약을 통해 논의 되고 있으며, 우리나라도 환경보존 계획을 수립하여 실천하고 있다.In general, the damage caused by environmental pollution is not limited to any country but is raised as a problem related to the survival of all human beings, and it is discussed through international agreements to solve this problem, and Korea has also established and implemented an environmental conservation plan.
특히 수질오염은 현재 심각한 상태이므로 수질오염을 방지하기 위해 하수처리장, 공단폐수처리장 건설을 증가시킴 따라 수질오염이 줄어드는 효과가 가시적으로 나타나기는 하지만 처리시 발생하는 슬러지의 발생량이 급격히 증가함에 따라 슬러지의 처리에 대한 많은 문제점들이 대두되고 있다.In particular, since water pollution is a serious condition, the effect of water pollution is reduced by increasing the construction of sewage treatment plants and industrial wastewater treatment plants to prevent water pollution, but the sludge generated during treatment increases rapidly. Many problems with processing have arisen.
현재 슬러지의 처리는 주로 매립에 의존하고 있는 실정이나 매립장부지 부족 및 침출수에 의한 토지와 지하수오염 등 2차환경오염을 일으키게 되므로 이제는 슬러지를 소각처리하는 방향으로 바뀌고 있다.At present, the treatment of sludge has been changed to incineration of sludge due to the fact that it is mainly dependent on landfill, but there is a lack of landfill site and secondary environmental pollution such as land and groundwater pollution caused by leachate.
그렇지만 슬러지 소각 기술에 대하여 겸험이 많지 않아 무분별한 소각처리장치들이 난립하게 되어 많은 시행착오를 겪고 있으며, 또 이러한 설비들의 규모가 대형화됨에 따라 많은 시설비가 투입될 뿐만 아니라 많은 운영비가 소요되기 때문에 경제성이 떨어지는 단점이 있다.However, as the sludge incineration technology is not very experienced, indiscriminate incineration equipments suffer from trial and error, and as the scale of these facilities increases, not only does it cost a lot of facilities but also costs a lot of operating costs. There are disadvantages.
이러한 문제점들을 해결하기 위해 본출원인은 특허출원 제2000-24713호로 슬러지를 다단의 건조실린더로 이송시키면서 건조시켜 수분 함수율 80%의 슬러지를 30%이하의 높은 건조효율로 건조하고, 또 건조된 슬러지나 음식물 쓰레기를 고체화하여 이를 연소실에서 소각 처리하므로써 발생되는 폐열을 다시 슬러지 건조에 이용하도록 한 바 적은 연료로 운전 가능함과 동시에 에너지효율을 향상시키므로 운영비를 줄일 수 있는 슬러지 소각처리방법 및 그 장치를 소개한 바 있다.In order to solve these problems, the present applicant has to apply the patent application No. 2000-24713 and transport the sludge to the multi-stage drying cylinder to dry it, and then dry the sludge with 80% water content with a high drying efficiency of 30% or less. Sludge incineration method and device that can reduce operating costs by improving energy efficiency while operating with less fuel, by using waste heat generated by solidifying food waste and incineration in combustion chamber There is a bar.
이러한 슬러지 소각처리방법에 의해 많은 연료를 줄일 수 있고, 또 슬러지를 효과적을 처리할 수는 있으나, 근본적으로 탈수 효율을 높이지 않으면 건조시 수분을 증발시키기 위한 많은 에너지가 필요하다.This sludge incineration process can reduce a lot of fuel and can effectively treat the sludge, but if the dehydration efficiency is not fundamentally increased, a lot of energy is required to evaporate moisture during drying.
하지만 지금까지는 슬러지를 탈수시키는 방법으로 원심탈수나 프레스를 이용한 단순 압착탈수 방식으로 실시하고 있어 그 효율이 매우 떨어지는 단점이 있었다.However, until now, as a method of dewatering sludge, a simple compression dehydration method using centrifugal dehydration or a press has been used, and its efficiency is very low.
본 발명은 본 출원인에 의해 선출원된 슬러지 처리장치의 효율을 더욱 상승시킬 수 있도록 하기 위해 건조 및 소각장치로 유입되기전 행해지는 슬러지 탈수공정에서 현재 실시하고 있는 원심탈수와 단순압착탈수의 비효율적인 방법으로부터 벗어나 보다 탈수효율을 극대화 하므로써 건조효율을 더욱 상승시키고, 그에 따라 소각에 소요되는 연료소모를 최소화할 수 있는 새로운 슬러지 탈수장치를 제공하는데 그 목적이 있다.The present invention is an inefficient method of centrifugal dehydration and simple compression dewatering currently carried out in the sludge dewatering process performed before entering the drying and incineration apparatus in order to further increase the efficiency of the sludge treatment apparatus previously filed by the applicant. The purpose of the present invention is to provide a new sludge dewatering device that can further increase the drying efficiency by maximizing the dewatering efficiency, thereby minimizing the fuel consumption for incineration.

도 1은 본 발명의 구조를 나타낸 탈수장치의 구조도이다.1 is a structural diagram of a dehydration apparatus showing the structure of the present invention.
참조번호 30은 슬러지 건조 및 소각처리장치이며, 상부에는 슬러지가 유입되는 유입호퍼가 설치되어 있다.Reference numeral 30 denotes a sludge drying and incineration treatment apparatus, and an inflow hopper into which sludge flows is installed.
본 발명은 상술한 유입호퍼로 슬러지를 이송시키는 이송컨베이어(10)를 이용하여 슬러지를 탈수 시키는 탈수장치로서, 도 1은 이러한 탈수장치를 도시하고 있다.The present invention is a dewatering device for dewatering the sludge by using the conveying conveyor 10 for transporting the sludge to the inlet hopper described above, Figure 1 shows such a dewatering device.
이송컨베이어(10)는 양측에 이송롤러(12a)(12b)가 설치되어 있고, 그 둘레로 슬러지는 걸러내고 수분은 배출시키는 다공체의 이송스크린 벨트(11)가 감겨 있다.The conveying conveyor 10 is provided with conveying rollers 12a and 12b on both sides, and the conveying screen belt 11 of the porous body for filtering sludge around and discharging water is wound.
이송컨베이어(10)의 긴장측 이송스크린 벨트(11)의 하부에는 촘촘하고 일정한 간격으로 다수개의 수평유지롤러(14)가 설치되어 있고, 하부에는 이송컨베이어(10)를 진동시키는 진동모터(15a)(15b)가 설치되어 있다.The lower side of the conveying screen belt 11 of the conveying conveyor 10 is provided with a plurality of horizontal holding rollers 14 at close and constant intervals, and a lower vibration motor 15a for vibrating the conveying conveyor 10. 15b is provided.
이 이송컨베이어(10)의 상부에는 이송컨베이어(10)와 동일방향으로 회전하는 압착컨베이어(20)가 설치되어 있다.On the upper portion of the conveying conveyor 10, a pressing conveyor 20 which rotates in the same direction as the conveying conveyor 10 is provided.
압착컨베이어(20)의 양측에도 구동롤러(12a)(12b)가 설치되어 있고, 그 둘레에는 이송스크린 벨트(11)어와 같이 슬러지는 걸러내고 수분은 배출시키는 다공체의 압착스크린 벨트(21)가 감겨있다. 또 이송스크린 벨트(11)와 접하는 압착스크린벨트(21)의 상부에는 압착스크린 벨트(21)를 이송스크린 벨트(11)쪽으로 밀착시키는 다수개의 가압롤러(24)들이 촘촘하고 일정한 간격으로 설치된다. 그리고 압착컨베이어(20)는 이송컨베이어(10)와 만나는 초입부에서 후미부로 가면서 이송스크린 벨트(11)와 압착스크린 벨트(21)의 간격이 점점 좁아지도록 설치되며, 압착컨베이어(20)의 속도를 이송컨베이어(10)보다 속도가 약간 느리게 설정되어 슬러지의 탈수시 압착스크린 벨트(11)가 이송스크린 벨트(21)로 이송되는 슬러지를 압착시킴과 동시에 부비면서 탈수시켜 탈수효과가 상승되도록 되어 있다.Driving rollers 12a and 12b are provided on both sides of the pressing conveyor 20, and a porous pressing screen belt 21 is wound around the circumference to filter sludge and discharge moisture, such as the transfer screen belt 11. have. In addition, the upper portion of the pressing screen belt 21 in contact with the conveying screen belt 11 is provided with a plurality of pressing rollers 24 closely contacting the pressing screen belt 21 toward the conveying screen belt 11 at regular intervals. And the pressing conveyor 20 is installed so that the distance between the conveying screen belt 11 and the pressing screen belt 21 is gradually narrowed from the beginning to the rear end meet with the conveying conveyor 10, the speed of the pressing conveyor 20 The speed is set slightly slower than the conveying conveyor 10 so that when the sludge is dewatered, the pressing screen belt 11 compresses the sludge conveyed to the conveying screen belt 21 and at the same time swells and dehydrates to increase the dewatering effect.
이러한 구조로 되어 있는 본 발명의 탈수장치의 작동상태를 살펴보면 다음과 같다.Looking at the operating state of the dewatering device of the present invention having such a structure as follows.
먼저 이송컨베이어(10)에 슬러지를 공급하게 되면 슬러지는 이송스크린 벨트(11)를 타고 슬러지 건조 및 소각장치(30)로 이송된다. 이송시 수평유지롤러(14)를 통해 이송스크린 벨트(11)는 수평을 유지한다.First, when the sludge is supplied to the conveying conveyor 10, the sludge is transferred to the sludge drying and incineration device 30 by the transfer screen belt 11. During the transfer, the transfer screen belt 11 is kept horizontal through the horizontal roller 14.
슬러지는 이송되는 과정에서 압착컨베이어(20)의 초입부에 접어들게 되면서 압착스크린 벨트(21)가 이송스크린 벨트(11)로 밀착되어 슬러지는 탈수되기 시작한다. 특히 초입부는 압착스크린 벨트(21)와 이송스크린 벨트(11)간의 간격이 넓어 슬러지는 원활하게 유입되고 유입후 압착스크린 벨트(21)와 이송스크린 벨트(11)간의 간격이 점점 좁아지도록 되어 있기 때문에 슬러지에 높은 압력이 가해지게 되어 탈수정도는 상승곡선을 그리게 된다. 이와 더불어 압착컨베이어(20)는 이송컨베이어(10)보다 속도가 약간 느리므로 결과적으로 압착스크린 벨트(21)가 이송스크린 벨트(11)위의 슬러지를 부비면서 압착하게 됨과 동시에 이송컨베이어(10)와 압착컨베이어(20)에 설치된 진동모터(25a)(25b)에 의해 진동이 발생하기 때문에 탈수효과는 더욱더 높아진다.As the sludge enters the initial part of the pressing conveyor 20 in the process of being transported, the pressing screen belt 21 is in close contact with the transfer screen belt 11 and the sludge starts to be dewatered. In particular, the initial part is widened between the pressing screen belt 21 and the conveying screen belt 11 so that the sludge is smoothly introduced and the interval between the pressing screen belt 21 and the conveying screen belt 11 is gradually narrowed after the inlet. High pressure is applied to the sludge and the degree of dehydration is rising. In addition, the pressing conveyor 20 is slightly slower than the conveying conveyor 10, and as a result, the pressing screen belt 21 compresses the sludge on the conveying screen belt 11 while simultaneously compressing the conveying conveyor 10 with the conveying conveyor 10. Since vibration is generated by the vibration motors 25a and 25b installed in the crimping conveyor 20, the dehydration effect is further increased.
한편, 탈수효과를 더욱 높이기 위해 압착컨베이어(20)의 구동롤러(22a)(22b)를 버큠롤러로 구성할 수 있다. 즉, 구동롤러(22a)(22b)의 둘레에 도면에 도시되지 않은 썩션구멍을 다수개 형성하고, 그 내부는 도면에 도시되지 않은 버큠펌프와 연결시켜 썩션구멍을 통해 수분을 흡입할 수 있도록 구성한다.On the other hand, in order to further increase the dehydration effect, the driving rollers 22a and 22b of the pressing conveyor 20 can be configured as a holding roller. That is, a plurality of slack holes not shown in the drawings are formed around the driving rollers 22a and 22b, and the inside thereof is connected to a vacuum pump not shown in the drawings so as to suck moisture through the slack holes. do.
이와 같이하면 유입되는 슬러지의 수분을 초입부에서 강제흡입하고, 또 후미부에서도 탈수된 슬러지로부터 수분을 강제 흡입하는 등 2차례에 걸처 수분을 강제 흡입하기 때문에 더욱더 높은 탈수효과를 얻을 수가 있다.In this way, even more dehydration effect can be obtained because the water is forced to be sucked in two times, such as forced suction of moisture from the introduced sludge, and forced suction of water from the dewatered sludge at the rear part.
이상에서 살펴본 바와 같이 본 발명은 슬러지를 이송컨베이어로 이송시키는 과정에서 압착컨베이어로 압착시키면서 속도차를 주어 슬러지를 부비면서 압착시키도록 함과 동시에 진동을 주고 또 버큠롤러로 수분을 강제흡입 시켜주도록 되어 있으므로 슬러지의 탈수효과가 극대화되는 장점이 있다. 이러한 높은 탈수효과에 의해 슬러지의 건조시 연료의 절감효과가 높고 또 소각시 연소효율을 향상시킬 수 있고, 또 완전연소에 따른 공해물질의 발생을 최소화할 수 있는 효과가 있다.As described above, in the present invention, while the sludge is conveyed to the conveying conveyor, the present invention compresses the sludge and compresses the sludge with the speed difference while compressing the sludge into the conveying conveyor. Therefore, there is an advantage that the dewatering effect of the sludge is maximized. This high dehydration effect is a high fuel saving effect when the sludge is dried, and can improve the combustion efficiency when incinerated, and minimize the generation of pollutants due to complete combustion.
