Method for the conversion of the anaerobic bacteria of methane and the organic waste material of fertilizer

摘要

Sedimentation-type centrifuge includes the screw conveyor with a main body (4), and carrying includes a screw of one or more flights (7,7 ') and with the nominal transport speed changed along the longitudinal axis. One entrance (6) is by the screw conveyor offer for material to be separated. Screw conveyor is provided with a baffle (8,8 '), in a kind of cylindrical separate section (17) and an at least partly segmentation separating tank in conical discharge part (18). The baffle (8 of upstream immediately, 8 ') transition part (19) setting has middle than between the variation of a bigger nominal transport speed, the nominal transport speed established by the variation (21) of the screw pitch of screw rod in separate section (17) in transition part (19) in separate section (17) and discharge portion (18), screw conveyor (3) before transition part (19).
