Apparatus for cleaning flue gas of metallurgic plant e.g. converter, has pre-cleaning stage and main treatment stage formed in common housing, where fine purification of flue gas is carried out in main treatment stage

The apparatus (1) has a metallurgical plant connected with a pre-cleaning stage (3) by a connecting line (2). Pre-cleaning and cooling of flue gas is carried out by water. Fine purification of the flue gas is carried out in a main treatment stage (4). The pre-cleaning stage and the main treatment stage are formed in a common housing (5). The pre-cleaning stage is provided with an injection nozzle (9) in which flow speed of the flue gas is increased. A lockable discharge port (12) is formed in a wall of the housing that is bordered on a water catchment basin (11). The main treatment stage is designed as a wet electrostatic filter (6). An independent claim is also included for a method for cleaning of flue gas of a metallurgic plant. Die Erfindung betrifft ein Verfahren und eine Vorrichtung (1) zum Reinigen von Rauchgas einer metallurgischen Anlage, umfassend eine durch eine Verbindungsleitung (2) mit der metallurgischen Anlage verbindbare Vorreinigungsstufe (3), in der eine Vorreinigung und Kühlung des Rauchgases unter Verwendung von Wasser erfolgt, und eine der Vorreinigungsstufe (3) nachfolgende Hauptreinigungsstufe (4), in der eine Feinreinigung des Rauchgases erfolgt, wobei die Vorreinigungsstufe (3) und die Hauptreinigungsstufe (4) in einem gemeinsamen Gehäuse (5) ausgebildet sind.
