The waste heat contained in the air is supplied to the unit 11 and reused for drying the sludge s.

운반유닛(20)은 본체를 따라 슬러지(s)를 운반하기 위한 것으로, 본 실시예의 경우 운반유닛으로는 컨베이어 밸트(20)가 채용된다. 컨베이어 밸트(20)는 본체(10)의 길이방향(즉, 슬러지의 이동방향)을 따라 이격되게 배치된 한 쌍의 회전 축(21)과, 밸트(22)를 포함한다. 밸트(22)는 망 형태로 형성되며, 한 쌍의 회전축(21)을 함께 감싸도록 결합된다. 회전축(21)의 회전시 밸트(22)는 본체의 길이방향으로 이동하며, 이에 따라 공급부(111)로부터 밸트(22)의 상면으로 공급된 슬러지(s)가 운반된다.The conveying unit 20 is for conveying the sludge s along the main body, and in this embodiment, the conveyor belt 20 is adopted as the conveying unit. The conveyor belt 20 includes a pair of rotation shafts 21 and a belt 22 that are spaced apart along the longitudinal direction of the main body 10 (that is, the sludge moving direction). Belt 22 is formed in the form of a mesh, it is coupled to surround a pair of rotating shaft 21 together. When the rotating shaft 21 is rotated, the belt 22 moves in the longitudinal direction of the main body, whereby the sludge s supplied from the supply part 111 to the upper surface of the belt 22 is conveyed.

발열유닛(30)은 슬러지(s)를 건조 및 탄화시키기 위한 것으로, 하우징(31)과, 단열부재(32)와, 할로겐 램프(34)와, 방열판(35)을 포함한다.The heat generating unit 30 is for drying and carbonizing the sludge s, and includes a housing 31, a heat insulating member 32, a halogen lamp 34, and a heat sink 35.

하우징(31)은 일면이 개구된 형태인 'ㄷ'자 모양으로 형성된다. The housing 31 is formed in a 'c' shape in which one surface thereof is opened.

단열부재(32)는 일측에 개구부(開口部)가 형성된 'ㄷ'자 형태, 즉 일면이 뚫려진 형태로 형성되며, 하우징(31)의 내부에 배치된다. 그리고, 단열부재(32)의 내면에는 반사피막(33)이 형성되어 있다. 이하, 단열부재(32)의 성분 및 제작과정에 관하여 상세하게 설명한다. The heat insulating member 32 is formed in a 'c' shape having an opening (開口 部) at one side, that is, in a form in which one surface is perforated, and is disposed in the housing 31. The reflective film 33 is formed on the inner surface of the heat insulating member 32. Hereinafter, the components and manufacturing process of the heat insulating member 32 will be described in detail.

본 실시예의 경우, 단열부재(32)는 알루미나와 실리카를 주성분으로 하는 세라믹 보드로 이루어진다. 세라믹 보드를 'ㄷ'자 형태로 가공한 후, 가공된 단열부재의 내면에 액상의 이산화규소(SiO2) 또는 크롬을 충분히 도포한 후 300도 이상의 온도에서 열처리한다. 그러면, 열처리 과정에서 세라믹 보드에 포함되어 있던 수분이 증발되고, 세라믹 보드에 포함된 유기물과 불순물이 소각되어 없어지므로, 수많은 공극이 생겨나 초다공체가 되며, 액상의 이산화규소(또는 크롬)가 유리 결정화되면서 단열부재(32)의 내면에 반사피막(33)이 형성된다. 그리고, 이와 같이 제작된 단열부재(32)는, 무게가 매우 가볍고 탄성을 지니므로, 관리(제작 및 설치과 정)이 편리하며, 후술하는 바와 같이 단열부재의 내부에 배치되는 할로겐 램프를 외부의 충격으로부터 효율적으로 보호할 수 있다.In the present embodiment, the heat insulating member 32 is made of a ceramic board mainly composed of alumina and silica. After the ceramic board is processed into 'c' shape, the liquid silicon dioxide (SiO 2 ) or chromium is sufficiently coated on the inner surface of the processed heat insulating member, and then heat-treated at a temperature of 300 degrees or more. Then, during the heat treatment process, the moisture contained in the ceramic board is evaporated, and the organic matter and impurities contained in the ceramic board are incinerated and disappeared, so that many voids are formed and become a superporous body, and liquid silicon dioxide (or chromium) is glass crystallized. While the reflective film 33 is formed on the inner surface of the heat insulating member 32. In addition, since the heat insulating member 32 manufactured as described above has a very light weight and elasticity, it is easy to manage (manufacture and install). Can be efficiently protected from

할로겐 램프(34)는 단열부재(32)의 내부에 배치된다. 할로겐 램프(34)는 전원 인가시 사방으로 열과 빛의 형태로 에너지를 방출하는데, 이때 도 3에 도시된 바와 같이 방출된 에너지는 직접 또는 반사피막에 반사된 후 방열판(35)으로 전달된다.The halogen lamp 34 is disposed inside the heat insulating member 32. The halogen lamp 34 emits energy in the form of heat and light in all directions when power is applied, and as shown in FIG. 3, the emitted energy is directly or reflected by a reflective film and then transferred to the heat sink 35.

방열판(35)은 판 형상으로 형성되며, 세라믹 유리 재질로 이루어진다. 방열판(35)은 단열부재(32)의 개구부를 막도록 하우징(31)에 결합된다. 할로겐 램프(34)에서 방출된 에너지는 방열판(35)에 흡수되어 원적외선의 빛과 열 에너지로 변환되며, 방열판(35) 전체에서 고르게 방사된다.The heat sink 35 is formed in a plate shape and is made of a ceramic glass material. The heat sink 35 is coupled to the housing 31 to block the opening of the heat insulating member 32. The energy emitted from the halogen lamp 34 is absorbed by the heat sink 35 and converted into light and heat energy of far infrared rays, and is evenly radiated throughout the heat sink 35.

한편, 슬러지(s)를 전체적으로 고르게 건조하기 위하여 상기 발열유닛(30)은 컨베이어 밸트(20)의 상측 및 하측에 복수로 설치된다. 본 실시예의 경우, 발열유닛은 4개씩 짝을 이루어, 컨베이어 밸트(20)의 상측 및 하측에 각각 2개씩 설치되는데, 이때 방열판(35)이 컨베이어 밸트(20)를 향하도록 경사지게 설치된다. 그리고, 이와 같은 발열유닛의 짝(4개)은 본체의 길이방향(슬러지의 운반방향)을 따라 복수로 설치된다.On the other hand, in order to evenly dry the sludge (s) as a whole, a plurality of the heating unit 30 is installed on the upper side and the lower side of the conveyor belt (20). In the case of the present embodiment, the heat generating unit is paired four by two, respectively installed on the upper and lower sides of the conveyor belt 20, wherein the heat sink 35 is installed to be inclined toward the conveyor belt (20). The pair of four heat generating units is provided in plural along the longitudinal direction of the main body (the sludge conveying direction).

받침판(40)은 컨베이어 밸트의 하측에 배치되며, 컨베이어 밸트(20)에서 떨어진 물이나 슬러지 조각들이 받침판에 모인다.The support plate 40 is disposed below the conveyor belt, and water or sludge pieces that are separated from the conveyor belt 20 are collected on the support plate.

한편, 슬러지 건조장치에는 팬(미도시)이 더 설치되어 있다. 팬은 본체의 수증기 제거부(13)에 설치되며, 슬러지가 원활하게 건조되도록 바람을 형성한다.On the other hand, the sludge drying apparatus is further provided with a fan (not shown). The fan is installed in the steam removal unit 13 of the main body, and forms a wind so that the sludge dries smoothly.

이하, 상술한 바와 같이 구성된 슬러지 건조장치(100)를 이용하여 슬러지를 건조하는 과정에 관하여 설명한다.Hereinafter, a process of drying the sludge using the sludge drying apparatus 100 configured as described above will be described.

먼저, 본체의 공급부(111)로 슬러지를 주입하면 이 슬러지가 밸트(22) 상으로 공급되며, 공급된 슬러지는 유동관(16)을 통해 공급된 공기에 포함되어 있는 폐열에 의해 예열(가열) 된다. 이후, 슬러지는 가열부(12)를 통과하면서 가열부에 설치되어 있는 가열유닛(30)에 의해 고온으로 가열되며, 수증기 제거부(13)를 통과하는 과정에서 가열유닛(30)에서 방사되는 열 및 팬에 의해 발생되는 바람에 의해 슬러지에 포함된 대부분의 물기가 빠른 속도로 증발하게 된다. 이와 같이 대부분의 물기가 제거된 슬러지는 건조/탄화부(14)를 통과하면서 완전히 건조 및 탄화되며, 이후 외부로 배출되게 된다.First, when the sludge is injected into the supply portion 111 of the main body, the sludge is supplied onto the belt 22, and the supplied sludge is preheated (heated) by waste heat contained in the air supplied through the flow pipe 16. . Subsequently, the sludge is heated to a high temperature by the heating unit 30 installed in the heating unit while passing through the heating unit 12, and heat radiated from the heating unit 30 in the process of passing through the steam removal unit 13. And most of the water contained in the sludge by the wind generated by the fan will evaporate at a high speed. As such, most of the sludge from which water is removed is completely dried and carbonized while passing through the drying / carbonation unit 14 and then discharged to the outside.

본 실시예에 따르면, 할로겐 램프(34)에서 발생된 고온의 열 및 빛이 방열판(35)을 통과하면서 원적외선 형태의 에너지로 변환된 후 슬러지에 조사되므로, 슬러지의 겉과 속이 고르게 건조/탄화된다. 즉, 할로겐 램프(34)에서 발생된 고온의 열이 슬러지에 직접 조사되는 경우에는 슬러지의 표면만이 집중적으로 건조/탄화되지만, 본 실시예의 경우에는 원적외선 형태의 에너지가 슬러지의 내부까지 침투되므로 슬러지의 표면 및 내부가 전체적으로 고르게 건조/탄화되게 되며, 그 결과 슬러지의 품질이 균일하게 된다.According to the present embodiment, since the heat and light of the high temperature generated by the halogen lamp 34 passes through the heat sink 35 and is converted into energy in the form of far-infrared rays, the sludge is irradiated onto the sludge so that the outside and the inside of the sludge are evenly dried / carbonized. . That is, when the high temperature heat generated by the halogen lamp 34 is directly irradiated to the sludge, only the surface of the sludge is concentrated / dried intensively, but in this embodiment, since the far-infrared energy penetrates to the inside of the sludge, the sludge The surface and the interior of the surface are evenly dried / carbonized, resulting in a uniform sludge quality.

그리고, 발열유닛(30)이 밸트(22)의 상측 및 하측에 각각 배치되어 있을 뿐 아니라, 할로겐 램프(34)에서 발생된 열/빛 에너지가 방열판(35)에서 고르게 확산된 후 넓은 면적을 통해 슬러지로 방사되므로 슬러지를 균일한 온도분포에서 건조 할 수 있으며, 그 결과 슬러지를 균일하게 건조할 수 있다.In addition, the heat generating unit 30 is not only disposed above and below the belt 22, but also through a large area after the heat / light energy generated from the halogen lamp 34 is evenly diffused in the heat sink 35. Since the sludge is radiated, the sludge can be dried at a uniform temperature distribution, and as a result, the sludge can be dried uniformly.

또한, 슬러지 건조에 이용되고 남은 폐열을 재활용하므로, 에너지 효율 및 경제성이 향상된다.In addition, since the waste heat remaining in the sludge drying is recycled, energy efficiency and economy are improved.
