Abstract
The invention relates to an apparatus for treatment of material, especially for thermal and/or chemical treatment, having an ascending pipeline branch, a diversion chamber and at least one descending pipeline branch. In the diversion chamber there is provided a deflecting wall that is oriented substantially transversely to the direction of flow of the material entering the diversion chamber via the ascending pipeline branch.
Claims12
Apparatus for the heat treatment of meal-form raw material, which is pre-heated in a pre-heating stage, calcined in a calcining stage, undergoes final roasting in a combustion stage and is cooled in a cooling stage, wherein the calcining stage contains a pipeline through which the exhaust gases of the combustion stage flow having an ascending branch, at least one descending branch and a diversion zone arranged therebetween, characterised in that the diversion zone is formed by a diversion chamber (2) that comprises a first section (2b) that is widened compared with the cross-section of the ascending pipeline branch (1) and is bounded upwardly by a deflecting wall (2a) oriented substantially transversely to the direction of flow of the material entering the diversion chamber (2) via the ascending pipeline branch (1), adjoining which first section is at least one second section (2c) that runs obliquely downwards and tapers conically to the cross-section of the descending pipeline branch (3, or 3a, 3b).
Apparatus for the heat treatment of meal-form raw material, which is pre-heated in a pre-heating stage, calcined in a calcining stage, undergoes final roasting in a combustion stage and is cooled in a cooling stage, wherein the calcining stage contains a pipeline through which the exhaust gases of the combustion stage flow having an ascending branch, at least one descending branch and a diversion zone arranged therebetween, characterised in that the diversion zone is formed by a diversion chamber (2′) that comprises a first section (2′b), which is widened compared with the ascending pipeline branch (1), and a second section (2′c), which is bounded by a defecting wall (2′a) oriented substantially transversely to the direction of flow of the material entering the diversion chamber (2′) via the ascending pipeline branch (1), wherein the descending pipeline branch (3, or 3a, 3b) projecting in the manner of an immersion pipe into the diversion chamber (2′) is lead obliquely downwards out of the diversion chamber.
