Abstract
During thermal treatment in a melting cyclone of solids that yield molten products at treatment temperatures, an exhaust gas is separated from the melt in an apparatus following the melting cyclone. The separation of the exhaust gas is implemented in a cyclone-like separating chamber that is fashioned such that a thermal after-treatment of the melt and/or of the exhaust gas can ensue therein in addition to the separation of the exhaust gas.
Claims16
An apparatus for high-temperature treatment of fine-grained solids having a melting cyclone, and a separating chamber in which the reaction products obtained in the melting cyclone are introduced and separated from one another, comprising:
- a separating chamber having a lateral admission opening;
- a transfer element;
- and
- a melting cyclone arranged such that the transfer element leads from an underside of the melting cyclone vertically obliquely downward in a curved path to the lateral admission opening of the separating chamber;
- and said separating chamber is fashioned cyclone-like forming a curved exhaust gas path and with a lower region for holding a molten bath of liquid reaction product, said lateral admission opening adapted for receiving the reaction products immediately above a surface of the molten bath contained within said lower region, and having an axial discharge opening for the exhaust gas, and a discharge opening for the liquid reactions product.
In an apparatus for high-temperature treatment of fine-grained solids having a melting cyclone, a separating chamber in which the reaction products obtained in the melting cyclone are introduced and separated, and a transfer element connecting the melting cyclone and separating chamber, the improvement comprising:
- arranging the melting cyclone above the separating chamber and connecting the transfer element to an admission opening in the separating chamber;
- the transfer element being shaped to conduct the reaction products in a vertically curved downward path;
- the separating chamber being a cyclone structure and holding a molten bath of liquid reaction product therein;
- and
- the admission opening being arranged above said molten bath.
