국내에서 발생하는 유기성 하수 슬러지 발생량은 하기의 표 1에 기재되어 있는 바와 같이, 2008년도의 경우 약 290만톤이고 유기성 폐수 슬러지 발생량은 257만톤이다.As shown in Table 1, the amount of organic sewage sludge generated in Korea is about 2.9 million tons in 2008 and 2.57 million tons of organic wastewater sludge is generated.
또한, 유기물이 포함되지 않은 무기성 슬러지 발생량은 약 261만톤 이며, 전체 슬러지 발생량 중에서 해양으로 배출되는 양은 235만톤으로 전체 발생량의 약 30% 정도로서, 이렇게 많은 양을 바다에 투기하고 있어 각종 해양 오염을 유발시키고 있는 실정이나, 런던협약에 의하여 2012년부터 상당량이 해양배출이 금지되고 있어 줄어드는 추세다.In addition, the amount of inorganic sludge without organic matter is about 2.61 million tons, and the total amount of sludge emitted to the ocean is 2.35 million tons, which is about 30% of the total amount generated. In fact, since 2012, a significant amount of ocean emissions have been banned by the London Convention.
또한, 2009년부터 정부에서 유기성 슬러지는 건조 후, 석탄과 혼합 연소시키는 방법으로 정책을 정하여 추진하고 있으나, 대부분 폐수 슬러지에 포함된 중금속과 건조한 슬러지의 낮은 발열량과 높은 함수율로 인하여 현재까지 화력발전소에서 석탄과의 혼합연소는 활발히 이루어지고 있지 않는 실정이다.In addition, since 2009, the government has decided to promote organic sludge after mixing with coal after drying.However, due to the low calorific value and high moisture content of heavy metals and dry sludge in most wastewater sludge, Mixed combustion with is not active.
따라서, 슬러지 처리의 다양한 방법과 친환경적이고 보다 경제적인 처리 방법이 절실한 실정에 있다.Therefore, various methods of sludge treatment and environmentally friendly and more economical treatment methods are urgently needed.

그리고, 상기 건조부(100)는 하나의 건조장치(200) 또는 다수의 건조장치(200)를 결합하여 이루어지는데, 건조장치(200)를 결합할 때에는 상기 건조장치(200)의 일측 상부에 위치하는 투입구(202)와 타측 하부에 위치하는 배출구(204)를 연결하여 상하 적층식으로 결합하여, 건조시키기 위한 슬러지의 함수율에 따라 적절한 개수로 결합하여 적절한 함수율을 가지도록 슬러지를 건조시키게 된다.In addition, the drying unit 100 is formed by combining one drying apparatus 200 or a plurality of drying apparatuses 200. When the drying apparatuses 200 are combined, the drying unit 100 is located above one side of the drying apparatus 200. By connecting the inlet 202 and the outlet 204 located on the lower side of the other to combine the upper and lower lamination type, by combining the appropriate number according to the moisture content of the sludge for drying to dry the sludge to have an appropriate moisture content.
이때, 본 발명의 건조장치(200)는 슬러지뿐만 아니라 톱밥이나 농산물과 같은 다양한 건조물을 건조시킬 수 있으나 설명의 편의를 위하여 슬러지를 기준으로 설명하면, 도 4 내지 도 6에 도시된 바와 같이, 슬러지를 공급받아 건조시키는 건조로(210)와 상기 건조로의 하부와 측부에 형성되어 상기 소성로(300)에서 배출되는 연소가스가 이동하는 연도(250)와 상기 건조로(210)에 공급된 슬러지를 이동시키는 이동장치(280)로 이루어진다.At this time, the drying apparatus 200 of the present invention can dry not only sludge, but also various dry matters such as sawdust or agricultural products. For convenience of description, the sludge will be described based on sludge, as shown in FIGS. 4 to 6. The flue gas is formed in the drying furnace 210 and the bottom and side of the drying furnace to dry the flue 250 and the sludge supplied to the drying furnace 210 to move the combustion gas discharged from the kiln 300 It consists of a moving device 280.
이때, 본 발명의 건조장치(200)는 슬러지 처리장치에 사용되지 않고, 별도의 가열로(미도시)를 사용할 경우 가열로에서 배출되는 연소가스를 상기 연도(250)로 공급하여 건조로(210)를 가열하게 되며, 상기 건조장치(200)의 측부에는 외부에 구비된 가열로에서 배출되는 연소가스를 공급받기 위한 연소가스 주입구(252)와 연소가스를 배출하기 위한 연소가스 배출구(254)가 각 단부에 형성된다.At this time, the drying apparatus 200 of the present invention is not used in the sludge treatment apparatus, and when a separate heating furnace (not shown) is used, the combustion gas discharged from the heating furnace is supplied to the flue 250 to dry the furnace 210. ) Is heated, and a combustion gas inlet 252 for receiving the combustion gas discharged from the heating furnace provided at the outside and a combustion gas outlet 254 for discharging the combustion gas are provided at the side of the drying apparatus 200. It is formed at each end.
한편, 상기 이동장치(280)는 건조로(210)의 내부에 구비되는 다수의 스크류봉(240)과 상기 건조로(210)의 길이방향 단부로 돌출되는 스크류봉(240)을 회전시키는 모터(220)로 이루어진다.On the other hand, the moving device 280 is a motor for rotating a plurality of screw rods 240 provided in the interior of the drying furnace 210 and the screw rods 240 protruding to the longitudinal end of the drying furnace 210 ( 220).
그리고, 상기 모터(220)와 스크류봉(240) 사이에는 감속기(230)가 구비되어 모터(220)의 회전력을 스크류봉(240) 각각으로 전달하여, 스크류봉(240)이 안정적으로 회전하게 된다.In addition, a reduction gear 230 is provided between the motor 220 and the screw rod 240 to transmit the rotational force of the motor 220 to each of the screw rods 240, so that the screw rod 240 rotates stably. .
이때, 인접한 스크류봉(240)은 서로 다른 방향으로 회전하도록 설치되어 있어 보다 안정적으로 건조로(210)에 투입된 슬러지를 이동시킬 수 있게 되는데, 상기 모터(220)는 일정한 방향으로만 회전하는 것이 아니라, 일정시간은 일측 방향으로 회전하고, 일정 시간은 타측 방향으로 회전하게 되어, 건조로(210)에 투입된 슬러지는 전후로 이동하게 된다.At this time, the adjacent screw rod 240 is installed to rotate in different directions to be able to move the sludge injected into the drying furnace 210 more stably, the motor 220 does not rotate only in a certain direction , The fixed time is rotated in one direction, the fixed time is rotated in the other direction, the sludge injected into the drying furnace 210 is moved back and forth.
여기서, 슬러지를 전방으로 이동하는 시간을 좀더 길게 하여, 슬러지가 전후로 이동하지만 조금씩 전방으로 이동하게 함으로써, 최종적으로는 건조장치(200)의 일측 하부에 위치하는 배출구(204)를 통하여 배출되게 된다.Here, the longer the time to move the sludge forward, the sludge moves forward and backward but little by little forward, it is finally discharged through the outlet 204 located on one side lower portion of the drying apparatus 200.
이렇게 슬러지를 단순히 전방으로만 이동하도록 하지 않고 전방으로 이동하다가 다시 후방으로 이동하는 과정을 반복하도록 함으로써, 슬러지가 완전히 교반되게 되어 슬러지에 포함된 수분이 보다 용이하게 증발하도록 하여 보다 신속하고 고르게 슬러지를 건조시킬 수 있게 된다.By repeating the process of moving forward and then backward again instead of simply moving the sludge forward, the sludge is completely stirred so that the water contained in the sludge evaporates more easily, thereby allowing the sludge to be more quickly and evenly. It can be dried.
그리고, 상기 건조로(210)의 상면(212)은 중심부에서 가장자리로 갈수록 하부로 경사지게 형성되고, 상기 상면(212)에는 일정 간격으로 배출덕트(206)가 구비되며, 상기 건조로(210)의 상부 양측에는 외부공기가 공급되는 외부공기 이동로(270)가 구비되고, 상기 건조로(210)의 내측 가장자리에는 물받이(214)가 구비된다.In addition, the upper surface 212 of the drying furnace 210 is formed to be inclined downward from the center to the edge, the upper surface 212 is provided with a discharge duct 206 at a predetermined interval, the of the drying furnace 210 External air movement paths 270 to which external air is supplied are provided at both upper sides, and drip trays 214 are provided at inner edges of the drying furnace 210.
여기서, 상기 건조로(210)의 하부 및 측부에 위치하는 연도(250)에서 방사되는 열에 의해 슬러지에 포함된 수분이 수증기로 변하여 상기 배출덕트(206)을 통하여 건조로(210)의 외부로 배출되게 되는데, 이 수증기는 배출덕트(206)로 이동하는 과정에서 건조로(210)의 상면(212)과 접촉되며, 상기 상면(212)의 양측에는 외부의 차가운 공기가 공급되는 외부공기 이동로(270)가 형성되어, 상면(212)과 접하는 수증기는 차가운 외부공기에 의해 응결되어 상면(212)의 경사진 방향을 따라 가장자리로 흘러내리게 되며, 상면의 가장자리(212)에 구비된 물받이(214)에서 응결수를 모아서 건조장치(200)의 외부로 배출하게 된다.Here, moisture contained in the sludge is converted into water vapor by heat radiated from the flue 250 located at the lower and side portions of the drying furnace 210 and discharged to the outside of the drying furnace 210 through the discharge duct 206. This water vapor is in contact with the upper surface 212 of the drying furnace 210 in the process of moving to the discharge duct 206, both sides of the upper surface 212, the external air movement path is supplied with external cool air ( 270 is formed, the water vapor contacting the upper surface 212 is condensed by cold external air flows down to the edge in the inclined direction of the upper surface 212, drip tray 214 provided at the edge 212 of the upper surface In the condensed water is collected and discharged to the outside of the drying apparatus 200.
따라서, 슬러지를 건조하면서 발생하는 가스를 건조장치(200)의 외부로 배출시에 가스에 포함된 수분을 미리 걸러주기 때문에 가스를 정화시킬 때, 수분을 제거하는 공정을 줄여줄 수 있게 된다.Therefore, the gas generated while drying the sludge is filtered in advance when the gas contained in the gas is discharged to the outside of the drying apparatus 200, thereby reducing the process of removing water when the gas is purified.
그리고, 상기 건조장치(200)에는 별도의 배관으로 연결되는 응결수 저장탱크(600)가 구비되어 건조장치(200)에서 걸러지는 응결수를 저장하여 재활용하거나 외부로 배출하게 되며, 상기 응결수 저장탱크(600)는 항상 부압을 유지함으로써 건조장치(200)에서 생성되는 응결수를 안정적으로 저장할 수 있게 된다.In addition, the drying apparatus 200 is provided with a condensation water storage tank 600 connected to a separate pipe to store and recycle the condensed water filtered by the drying apparatus 200 or to discharge the condensed water to the outside. The tank 600 is able to stably store the condensed water generated in the drying apparatus 200 by maintaining the negative pressure at all times.
여기서, 상기 건조장치(200)의 측부에는 상기 외부공기 이동로(270)로 외부공기를 공급받기 위한 외부공기 주입구(미도시)와 외부공기 배출구(274)가 구비되며, 외부공기 주입구에는 외부공기에 포함된 이물질을 걸러주는 필터(272)가 구비된다.Here, the side of the drying apparatus 200 is provided with an external air inlet (not shown) and an external air outlet 274 for receiving external air to the external air movement path 270, and the external air inlet is provided with external air. Filter 272 is provided to filter the foreign matter contained in.
이때, 상기 건조장치(200)의 외부공기 이동로(270)를 통하여 이동하면서 건조로(210)의 열기에 의해 가열된 외부공기는 상기 소성물 배출장치(400)를 통과하는 과정에서 배출된 소성물의 열기를 흡수하여 재가열되게 되며, 상기 건조로(210)의 내측 하부에는 형성된 공기 공급로(260)로 공급되게 된다.At this time, the external air heated by the heat of the drying furnace 210 while moving through the external air movement path 270 of the drying apparatus 200 is discharged in the process of passing through the plastic discharge device 400 The heat of the water is absorbed and reheated, and the lower portion of the drying furnace 210 is supplied to the formed air supply passage 260.
한편, 본 발명의 건조장치(200)가 슬러지 처리장치에 사용되지 않고 별도의 가열로(미도시)와 연결하여 사용할 경우, 외부공기 이동로(270)를 이동하면서 1차로 가열된 외부공기는 가열로(미도시)를 통과하면서 2차로 가열되어 건조로(210)의 내측에 구비되는 공기 공급로(260)로 공급되어 건조로(210)를 다시 가열하게 되므로, 보다 안정적으로 건조로(210)를 가열시키게 된다.On the other hand, when the drying apparatus 200 of the present invention is used in connection with a separate heating furnace (not shown) without being used in the sludge treatment apparatus, the external air primarily heated while moving the external air movement path 270 is heated. Since the second heating while passing through the furnace (not shown) is supplied to the air supply path 260 provided inside the drying furnace 210 to heat the drying furnace 210 again, the drying furnace 210 more stably. Will be heated.
그리고, 상기 공기 공급로(260)는 도 5에 도시된 바와 같이, 이동장치(280)를 형성하는 스크류봉(220)이 접하는 부분의 하부에 위치하게 되며, 상기 공기 공급로(260)의 측부에는 일정 간격으로 배출공(미도시)이 형성되어 공기 공급로(260)로 공급된 공기가 건조로(210)로 배출되게 된다.And, as shown in Figure 5, the air supply path 260 is located in the lower portion of the contact portion of the screw rod 220 forming the moving device 280, the side of the air supply path 260 There is a discharge hole (not shown) is formed at a predetermined interval so that the air supplied to the air supply path 260 is discharged to the drying furnace 210.
그래서, 상기 배출공으로 배출된 공기는 건조로(210)의 하부에 위치하는 슬러지나 건조물에 조사되어 슬러지나 건조물의 사이로 침투하여 건조물 사이에 위치하는 수분을 보다 신속하게 수증기로 변화시키게 된다.Thus, the air discharged to the discharge hole is irradiated to the sludge or dry matter located in the lower portion of the drying furnace 210 to penetrate through the sludge or dry matter to quickly change the water located between the dried water vapor.
