Environmentally friendly, self-contained, controllable plant for the continuous production of biochar with high yield, consistently high quality from biomass

摘要

An environmentally friendly plant for the continuous production of biochar from a Biomasseteilchen in a bed of moving bed with a shaft reactor (211) comprising a head end and a foot end (81) Schachtreaktormantel (71) for receiving the biochar, at least one particle conveyor for transporting the biomass particles in the shaft reactor (211), at least one ventilation metering device (111) for supplying the air into the shaft reactor (211), the top end of the shaft reactor (211) an entry port and the foot end (81) of the shaft reactor (211) have a discharge opening (161) a central portion (141) between the head end and the foot end (81), a grid (2x) in an interior of the shaft reactor (211) in a transition area (115) between the central portion (141) of the shaft reactor (211) and the foot end (81) is arranged to support the bed, characterized gekennze That is, the foot end (81) of the shaft reactor (211) has the ventilation metering device (111), the ventilation metering device (111) has an air pipe (311) and an outer pipe (121), the outer pipe (121) has an upper end of the air pipe (311 ), the outer tube (121) is movably connected to the air duct pipe (311), the air duct pipe (311) is connected to an outer air duct (412), via which air can be supplied from the outside, and the particle conveyor is arranged in the area of the head end, which comprises a pouring device, the pouring device has a continuously tiltable chute for uniform, controlled, stepless radial distribution and charging of the bed with biomass particles, the chute (4d) comprising a main drive device (2) from the drive device (8) about the vertical axis of rotation (V) is rotatably driven to feed the surface of the bed in the range to di e vertical pivot axis (V) thereof and the chute (4) about a, preferably transversely to the vertical axis of rotation (V) aligned, horizontal pivot axis (H) is designed tiltable.
