즉, 건조기와 소각로간의 원료오니를 조정하여 보내는 선행기술로서는 소각로에 적정하게 조정된 적량의 건조오니를 공급하기 위해 건조기에 원료오니의 유량, 수분량 및 배기가스의 온도 또는 습도를 측정하여 기내에서 오니의 경시변화를 잡아 소각로로 공급되는 오니량을 조절하도록 한 오니의 건조제어방법(일본국 특허공개 평성 3-137998호) 및 건조기와 소각로 사이에 중간저장조를 설치, 이 저장조내에 소각로의 출구가스 온도에 따라 제어되는 원료공급용 스크루우컨베이어를 설치한 오니건조 소각장치(일본국 특허공개 소화 56-91117호)등이 제안된바 있다.In other words, the prior art for adjusting and adjusting the raw material sludge between the dryer and the incinerator is to measure the flow rate of the raw sludge, the moisture content and the temperature or humidity of the exhaust gas to the dryer to supply the appropriate amount of dry sludge to the incinerator. Drying control method (Japanese Patent Publication No. Pyeong 3-137998) to control the amount of sludge supplied to the incinerator by catching the change over time, and installing an intermediate storage tank between the dryer and the incinerator, and the outlet gas temperature of the incinerator in this tank A sludge drying incinerator (Japanese Patent Laid-Open No. 56-91117) equipped with a screw conveyor for supplying raw materials controlled according to the above has been proposed.

그러나, 상기한 2가지의 제안을 포함한 공지의 각 건조소각 병설장치는 작업중에 발생한 건조기 또는 소각로 각 내부의 개별적, 경시적상황 변화에 대한 충분한 대처가 되지 않았다.However, each known drying incineration apparatus including the above two proposals did not sufficiently cope with individual and time-dependent changes in each of the dryers or incinerators generated during operation.

본 발명은 건조기와 소각로의 사이에 설치한 중간저장조에 해당하는 조 및 건조기 소각로 사이의 제어기구를 설치하는 것에 따라 원료 오니의 건조, 소각처리의 도중 정체 및 공해발생을 일으키지 않도록 하는 것이다.The present invention provides a control mechanism between the tank corresponding to the intermediate storage tank installed between the dryer and the incinerator and the dryer incinerator, so as not to cause stagnation and pollution during drying and incineration of the raw material sludge.

상기의 목적을 달성하기 위해 본 발명의 오니건조 소각장치는 건조기(11)과 소각로(21) 사이에 중간저장조(1)을 설치하고, 이 저장조(1)의 입구에 건조기(11)에서의 유입되는 유입컨베이어(3)을, 또 출구에 유출컨베이어(4) 및 소각로(21)로의 송입컨베이어(5)를 설치하며, 상기의 중간 저장조(1) 및 유입컨베이어(3)의 일측부에 배출부(6a) (6b)를 설치함과 동시에 중간저장조(1)에 여러층의 높이측정계(7) 및 수분량계(8)(채취구 8b에서 샘플링을 취해 측량하는 방식의 것을 포함)를 설치한다.In order to achieve the above object, the sludge drying incineration apparatus of the present invention has an intermediate storage tank (1) installed between the dryer (11) and the incinerator (21), and is introduced from the dryer (11) at the inlet of the storage tank (1). The inlet conveyor (3) and the outlet conveyor (4) and the inlet conveyor (5) to the incinerator (21) are installed at the outlet, and the outlet part (1) at one side of the intermediate reservoir (1) and the inlet conveyor (3). 6a) At the same time as (6b), a multi-level height measuring system (7) and a water level meter (8) (including sampling and sampling at the collecting port 8b) are installed in the intermediate storage tank (1).

또한 소각로(21)의 상측에는 소각로(21)내의 온도를 감지하는 온도감지기(10)를 부착하고 상기한 각계기류(7) (8) (10)에 각각 건조기(11), 소각로(21), 유입컨베이어(3), 송입컨베이어(5) 및 배출부(6a) (6b)의 작동을 제어하는 제어장치(작동부)를 설치하는 것이다.In addition, a temperature sensor 10 for sensing the temperature in the incinerator 21 is attached to the upper side of the incinerator 21, and the dryer 11, the incinerator 21, and the respective air streams 7, 8 and 10 are respectively attached. It is to install a control device (operation part) for controlling the operation of the inlet conveyor (3), the inlet conveyor (5) and the discharge part (6a) (6b).
