tunnelreaktor to soils of abandoned waste portions of organic

摘要

The invention relates to a tunnel reactor 1 for digesting organic waste materials added in portions, which tunnel reactor is aligned essentially horizontally in its longitudinal extension and has a rectangular to square through cross-section. Reference can be made to DE-OS 2844481 for the prior art. The solution according to this publication is based on municipal waste in the form of precompressed balls or in the form of a continuous extrudate being introduced in many pieces adjacently and one on top of the other into a climatised digestion hall as a reaction chamber. Disadvantages of this have proved to be the high expenditure for the material insertion apparatus, which is arranged outside the digestion hall, and can be brought into X-Y-Z alignment, and the material pressing at ambient temperature. According to the solution it is provided that a pressing shield 20, which can move horizontally to and fro in the reactor space 14 between a starting and final position 23/24, is configured, which clears in each case the material depositing in the feed area 12 in the direction of a shaping prechamber 13, and the material fed first is transported by a guided material portion into a ventilatable, horizontally and vertically expanded reactor space 14, which is furnished with a falling step 7.
