Abstract
Modularer Hochofen, dadurch gekennzeichnet, dass das Reaktionsgefäß samt Gebläseeinrichtung drehbar und kippbar ausgeführt ist,Modular blast furnace, characterized in that the reaction vessel together with the blower device is designed to be rotatable and tiltable,
Description
Ein Hochofen mit rotierendem und Kippbarem Reaktionsgefäss wird im seinen einzelnen Bearbeitungszonen mit elektrisch beheizten Platten und Strahlern betrieben.A blast furnace with a rotating and tiltable reaction vessel is operated in its individual processing zones with electrically heated plates and radiators.
HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
Hochöfen sind in industriellen Großanlagen gemauert, werden von oben beschickt und am Sockel bzw. Gestell abgestochen um das flüssige Metall zu gewinnen.Blast furnaces are bricked in large industrial plants, are charged from above and tapped at the base or frame to extract the liquid metal.
Dabei wird die zum Ausschmelzen des Metalls nötige Wärme durch Zumischen von Koks zum Erz bewirkt und die Mischung durch heiße Reduktionsgase vorgewärmt, getrocknet und der Sauerstoffanteil des Erzes reduziert. Die glühende Kohle gibt dabei die Energie und ihr heißes Reaktionsgas bringt Eisen und Schlacke zum Schmelzen.The heat required to melt the metal is generated by adding coke to the ore, and the mixture is preheated and dried using hot reducing gases, and the oxygen content of the ore is reduced. The glowing coal provides the energy and its hot reaction gas melts the iron and slag.
Dieser Vorgang erfordert nicht nur hohen Energieeinsatz durch die Kohle, sondern bewirkt auch den Ausstoß hoher Mengen an umweltschädlichem Co2 und Gichtgasen.This process not only requires a lot of energy from the coal, but also causes the emission of large quantities of environmentally harmful CO2 and flue gases.
AUFGABETASK
Die Aufgabe vorliegender Erfindung ist daher, die Verhüttung von Erzen in kleinerem Maßstab zu ermöglichen und umweltfreundlicher zu gestalten.The object of the present invention is therefore to enable the smelting of ores on a smaller scale and to make it more environmentally friendly.
STAND DER TECHNIKSTATE OF THE ART
Zur Verhüttung von Erzen in kleineren Anlagen werden überwiegend Aufschmelzvorgänge unter Einsatz elektrischer Energie angewendet; darunter das vielgenutzte Siemens-Martin-Verfahren, das vor allem zur Verarbeitung von Schrott in der Stahlproduktion Verwendung findet und das Metall durch Wirbelströme erhitzt.For the smelting of ores in smaller plants, melting processes using electrical energy are mainly used; including the widely used Siemens-Martin process, which is primarily used to process scrap in steel production and heats the metal with eddy currents.

Letztere Verfahren arbeiten zwar mit elektrischer Energie und etwas geringeren Emissionen als die konventionelle Hochofentechnik, weisen jedoch nur geringe Energieeffizienz auf.Although the latter methods work with electrical energy and slightly lower emissions than conventional blast furnace technology, they only have low energy efficiency.
LÖSUNGSOLUTION
Der erfinderische Schritt ist hier, den Wärmeeintrag ins Erz durch eine Anordnung von plattenförmigen elektrischen Heizelementen auf einen rotierenden Behälter zu bewirken, der von oben beschickt und durch einfaches Kippen geleert werden kann. Dabei erlauben die Plattenstacks für verschiedene Zonen des Hochofens jeweils angepasste Temperaturen. Dies verringert den Energieeinsatz, u.a, weil es die Anforderungen an die Kühlung verringert.The inventive step here is to bring about the heat input into the ore by means of an arrangement of plate-shaped electrical heating elements on a rotating container that can be charged from above and emptied by simply tilting. The plate stacks allow temperatures to be adjusted for different zones of the blast furnace. This reduces energy use, in part because it reduces cooling requirements.
