Abstract

Zur Entfernung von Öl aus ölhaltigem, nassem Walzenzunder, Walzenzunderschlamm und ähnlichen Stoffen ist vorgesehen, diese Stoffe in einem Durchlaufofen (12) in Verbindung mit einer Eisenerzsinteranlage zu behandeln. For removing oil from oily, wet Rolling scale, rolling mill sludge and similar substances it is planned to put these substances in a continuous furnace (12) in connection with an iron ore sintering plant to treat.

Heiße Kühlerabluft aus dem Sinterkühler (5) fließt im Gegenstrom zu Walzenzunder durch den Durchlaufofen (12). Dabei wird der Zunder getrocknet, und ein Teil des Öls verbrennt. Die Kühlerabluft wird dann mit den flüchtigen Ölen in dem Zündofen (3) der Sintermaschine (1) als Verbrennungsluft eingeleitet, wo die restlichen Öle verbrennen. Hierdurch wird vermieden, daß unverbrannte Öle sich in dem Elektrofilter (8) absetzen. Hot cooler exhaust air from the sinter cooler (5) flows in the Counterflow to mill scale through the continuous furnace (12). The scale is dried, and part of it of the oil burns. The radiator exhaust air is then with the volatile oils in the ignition furnace (3) of the sintering machine (1) initiated as combustion air, where the rest Burn oils. This avoids that unburned oils in the electrostatic precipitator (8) drop.

Trockner, von Öl befreiter Walzenzunder kann dem Mischgut (17) zugeführt werden. Dryer, oil-freed mill scale can be fed to the mix (17).
