Patent ID: 8439670

Claim:
A device for separating a solid material and a gas comprising, a. an ascending conduit for conducting a gas-solid material suspension having a solid material supply port for feeding in a solid material and a gas supply port for feeding in a gas, b. a descending helical and/or spiral conduit, in which the gas-solid material suspension is separated into a solid material flow and a gas flow by centrifugal forces, c. a diverter head that connects the ascending conduit with the helical and/or spiral conduit, d. connected to the end of the helical and/or spiral conduit a solid material conduit for discharging the flow of solid material and also e. connected to the end of the helical and/or spiral conduit a gas conduit for discharging the flow of gas, wherein a junction region to the ascending conduit the diverter head has a first cross-sectional shape and in the junction region to the helical and/or spiral conduit has a second cross-sectional shape and in that in a region of the diverter head at least one bend is provided in a conduit configuration.
