The device according to the invention for carrying out chemical and/or physical reactions between a solid material and a gas, in particular for the preheating, cooling and/or calcining of fine-grain materials, essentially comprises at least one helical and/or spiral conduit, in which the gas-solid material suspension is separated by centrifugal forces into a solid material flow and a gas flow, and, connected to the end of the helical and/or spiral conduit, at least one separation region, to which a solid material conduit for discharging the solid material flow and a gas conduit for discharging the gas flow are connected. The separation region is here formed by a lower part of the gas conduit, the separation region in the region of the junction of the helical and/or spiral conduit and the part of the gas conduit above and adjoining it having the same diameter. To form a swirling flow, the helical and/or spiral conduit opens out tangentially and at an angle to the horizontal of at least 30&#xb0; into the separation region.

Device and a method for carrying out chemical and/or physical reactions between a solid material and a gas as well as a plant for cement manufacture

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.

Device for separating a solid material and a gas and a plant for cement manufacture

A device for performing chemical and/or physical reactions between a solid material and a gas, especially for preheating, cooling and/or calcining fine-grained materials has at least three stages arranged one above the other, each stage comprising the following components: a. a gas-solids suspension duct for conducting a gas-solids suspension, b. means for separating the delivered solid material from the delivered gas, c. a solids duct for discharging the separated solid material, d. and a gas duct for discharging the separated gas, the gas duct of one stage merging into the gas-solids suspension duct of the next-higher stage and the solids duct of one stage joining the gas-solids suspension duct of the next lower stage. In addition, the junction of the solids duct and the gas-solids suspension duct of the third or a higher stage is provided below the highest point of the gas-solids suspension duct arranged two stages lower.
