ABSTRACT:
A dust pre-precipitator centrally supports a plurality of filters with dry filter elements; raw gas flows down in the pre-precipitator and emerges from the bottom thereof in a dust bag, and a reversal of gas flow obtains as it flows through the dust bag and into the filters through the respective inlets thereof; clean gas is extracted from the top of the filters, and cleaning gas can be selectively fed to them from the top thereof; each of the filters contains a funnel shaped transition, and a dust extraction device is disposed adjacent to a two-way flap so that counter flowing cleaning gas passing through said filter in down direction will be guided away from the dust bag into the extraction device.
