Embodiment Construction

[0022] figure 1 Denotes a fermentation apparatus having a closed horizontal vessel 1 with a feed opening 2 for the substrate to be treated at the front end and discharge openings 3 and 4 at the opposite end. A substrate consisting, for example, of biowaste or recycled raw materials is fed into the feed opening 2 of the container 1 via a feed screw 5 . A plurality of stirring elements 6 arranged transversely to the vessel axis, each having a separately driven stirring shaft 11 oriented transversely to the vessel axis, is arranged in the vessel 1 . Mounted on the stirring blades of the stirring mechanism 6 are a plurality of stirring rods 12 which are spaced apart in relation to the width of the container and are arranged on the stirring shaft at an angle of 120° relative to one another. Furthermore, the stirring shafts 11 are arranged at an axial distance which is smaller than the diameter of the stirring mechanism, so that the stirring rods 12 interlock. Reference numeral 13...

Abstract

The invention relates to a fermentation device for the biological degradation of a substrate containing organic material and for the recovery of the biogas that is produced in the degradation process. To circulate the substrate in the fermentation device and simultaneously remove deposited sediment, mixing units with transversal shafts (11) are arranged one behind the other in the fermentation device, the distance between their axes being smaller than the mixing unit diameter. This permits the mixing impellers (7) of the mixing units to pass through an overlap region (13) as the mixing unit shafts (11) rotate. Any sediment that has been deposited on the floor of the fermentation device can thus be transported from the front end to the removal end of said device.

Description

technical field [0001] The present invention relates to a fermentation device for biodegrading a substrate containing organic matter and obtaining the biogas produced by the degradation, comprising a closed elongated container with a feeding port for the substrate at the front end and a feed port at the opposite end of the container It is used for the discharge port of the substrate after treatment, and has at least one exhaust port of biogas. The container has a plurality of reaction chamber units, each reaction chamber unit includes a plurality of individually driven stirring mechanisms, and the stirring mechanism has circular shape. Moving stirring blades and a stirring shaft arranged transversely to the longitudinal extent of the vessel for thorough mixing of the substrate, and the invention relates to a method for operating the fermentation plant. Background technique [0002] For the fermentation of organic-containing substrates such as biowaste, food production residu...
