Abstract

The device according to the invention for separating a solid material and a gas substantially comprises 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, 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, a diverter head that connects the ascending conduit with the helical and/or spiral conduit, wherein in the region of the diverter head at least one bend is provided in the conduit configuration, connected to the end of the helical and/or spiral conduit a solid material conduit for discharging the flow of solid material and also connected to the end of the helical and/or spiral conduit a gas conduit for discharging the flow of gas.
