The utility model relates to the technical field of
sludge carbonization, and particularly discloses a
sludge carbonization device with a
dehydration pretreatment structure, which comprises a
carbonization box, the carbonization box is of a cuboid structure with a hollow rear part, a carbonization cylinder is fixedly arranged in the carbonization box, the carbonization cylinder is of a
hollow cylinder structure, and the
dehydration pretreatment structure is arranged in the carbonization box. And a heating base is arranged on the lower surface of the carbonization
barrel and fixedly installed on the inner wall of the carbonization box, a heating module is arranged in the heating base, and a discharging
pipe is arranged on the lower edge of the carbonization
barrel in a penetrating mode. According to the
sludge carbonization device with the
dehydration pretreatment structure, the carbonization
barrel and the heating base are arranged in the device to realize the carbonization process of sludge, and before entering the carbonization barrel, the sludge firstly enters the dehydration barrel driven by the second motor to be subjected to centrifugal dehydration treatment, so that the
moisture content in the sludge is reduced; the
dewatered sludge enters the subsequent carbonization process, so that the sludge can be carbonized more efficiently, the carbonization time is shortened, and the carbonization efficiency is improved.
