Gas supply and distribution center

摘要

The gas supply and distribution means comprises at least one gas distribution plate (13) composed of shaped blocks (14) through which extend gas ducts (15) having exit slots at the top sides of the shaped blocks. The gas distribution plate (13) is loaded with bulk material. The device may be used for instance as a gas cleaning plant, ret plate in composting systems, and as a combined gas cleaning and ret plate. The gas distribution plate (13) is enclosed at least partly by a collecting channel (16). Raw gas is fed through gas line (36) into an inlet chamber (25) from where it flows into the collecting channel (16) to be distributed from there to the gas ducts (15). The gas distribution plate (13) has an inclined runoff thus enabling excess water present in the filter medium to flow into the collecting channel (16) and from there, through a water conduit (26) to the inlet chamber (25) which contains a water reservoir and a spraying means to moisten raw gas prior to its distribution.
