Environmentally friendly, independently controllable plant for the continuous production of biochar, such as charcoal with high yield, consistently high quality from biomass, preferably wood

摘要

Environmentally-friendly independently controllable plant for the continuous production of biochar, such as charcoal, from a biomass, preferably wood, in a bed as a moving bed with a shaft reactor (1) with a head end and a foot end (8) comprising shaft reactor shell (7a) for receiving the biochar , at least one particle conveying device for conveying the biomass particles into the shaft reactor (1), at least one ventilation metering device (11) for feeding the air into the shaft reactor (1), the top end of the shaft reactor (1), an inlet opening and the foot end (8) of the shaft reactor ( 1) have a discharge opening (16), a central portion (14) between the head end and the foot end (8) is located, a collecting means connected to the discharge opening (5) for extinguishing the moving from the discharge opening of the shaft reactor biochar, wherein a grid (2) in an interior of the shaft reactor (1) in a Üb passage area (15) between the central portion (14) of the shaft reactor (1) and the foot end (8) is arranged to support the bed, characterized in that the foot end (8) of the shaft reactor (1) has the ventilation metering device (11), the vent metering device (11) comprises an air duct pipe (3) and an outer pipe (12), the outer pipe (12) accommodating an upper end of the air duct pipe (3), the outer pipe (12) movably connected to the air duct pipe (3), the air duct pipe (3) with an air outer tube (4), via which air can be supplied from the outside, is connected, and / or the particle conveyor is arranged in the region of the head end, which comprises a shaking means, the shaking means a shaking grate for uniform distribution and charging of the bed with Biomass particles, such as wood particles, and / or a distributor plate or a chute for the controlled feeding of the surface of the bed m it has biomass particles, preferably the foot end (8) of the shaft reactor shell (7a) conical, preferably with a funnel-shaped annular skirt (9) is formed.
