Abstract

본 발명은 슬러지 건조방법 및 그 장치를 개시한다.The present invention discloses a sludge drying method and apparatus thereof.

본 발명은 슬러지를 가압하여 소정의 형상으로 형상화하고, 형상화된 슬러지를 밀폐된 공간내에서 이송시키면서 가열하여 건조시키고, 상기 밀폐된 공간과 그 양단부가 연통되는 통로가 형성되어 이 통로를 통하여 상기 밀폐된 공간의 공기를 순환시키며, 상기 밀폐된 공간의 통로를 통하여 순환되는 공기로부터 수분을 제거하는 제습시키는 것에 그 특징이 있으며, 이는 슬러지를 저온건조함에 따른 건조효율을 향상시킬 수 있는 이점을 가진다.According to the present invention, the sludge is pressurized to be shaped into a predetermined shape, heated and dried while conveying the shaped sludge in an enclosed space, and a passage is formed in which the enclosed space communicates with both ends thereof. It is characterized by circulating the air of the closed space, dehumidifying to remove moisture from the air circulated through the passage of the closed space, which has the advantage that can improve the drying efficiency by the low temperature drying of the sludge.
