Description

Verfahren zur Gewinnung des Staubes aus den Flammengasen von Konvertern u. dgl. durch elektrische Gasreinigung. Die Verwendung von elektrischen Gasreinigern bei metallurgischen Öfen zur Ausscheidung und Gewinnung der Staubteilchen aus den abziehenden Gasen ist bekannt. Bei der Erfindung Bandelt es sich nun nicht allein um die Staubgewinnung aus Flammengasen, sondern darum, die Flammengase von Konvertern o. dgl. unmittelbar so zu erfassen, daß auch ihre Wärme zur vollen Ausnutzung gelangt. Während man bisher heiße Gase vor ihrem Eintritt in das Filter kühlte, findet die Wärmeabgabe gemäß der Erfindung in der die Staubteilchen niederschlagenden elektrischen Vorrichtung selbst statt.Process for extracting dust from converter flame gases and the like by electrical gas cleaning. The use of electric gas purifiers in metallurgical furnaces for the separation and recovery of dust particles from the withdrawing gases is known. The invention is not the only thing to do with it about the extraction of dust from flame gases, but rather about the flame gases from converters o. The like. Immediately to be recorded in such a way that their heat is also fully utilized. While hot gases were previously cooled before they entered the filter, the Heat emission according to the invention in the electrical which precipitates the dust particles Device itself instead.

Bisher hatman an eine solche allgemeineAusnutzung der heißen Konverterflammen nicht denken können, weil es an genügend widerstandsfähigen Niederschlagsvorrichtungen gefehlt hat. Erst der elektrische Gasreiniger, der gegen die mitgerissenen glühenden Staubteilchen bei Kühlung der Elektroden unempfindlich ist, gibt die Möglichkeit, die Konv erterflammen einer nutzbringenden Behandlung zu unterziehen. Zur Wärmeabgabe brauchen die Sammelelektroden der elektrischen Niederschlagsvorrichtung nur in an sich bekannter Weise als Röhren ausgebildet zu sein. die von Flüssigkeit, Gas, Luft oder sonst einem zu erhitzenden Medium umflossen und auf diese Weise wirksam gekühlt werden.So far there has been such a general use of the hot converter flames can not think because there are enough resistant precipitation devices was missing. First the electric gas cleaner, the one against the glowing swept away Dust particles are insensitive to the cooling of the electrodes, gives the possibility of to subject the converter flames to beneficial treatment. For heat dissipation need the collecting electrodes of the electric precipitation device only in on known to be designed as tubes. that of liquid, gas, air or otherwise flowed around a medium to be heated and effectively cooled in this way will.

Auf der Zeichnung ist eine Anlage zur Ausführung des Verfahrens in einer Ausführungsform beispielsweise dargestellt. Die Flammengase des Konverters I werden durch eine Haube 2 den Flammrohren 3 eines Dampfkessels 4 zugeleitet, die in Verbindung mit den Hochspannungselektroden 5 als elektrische Gasreiniger ausgebildet sind. Das von den Schwebeteilchen befreite Gas strömt bei G ab, der wertvolle Staub sammelt sich in dem Trichter 7.The drawing shows a system for carrying out the process in an embodiment shown for example. The converter flame gases I are fed through a hood 2 to the flame tubes 3 of a steam boiler 4, the in connection with the high-voltage electrodes 5 designed as an electric gas cleaner are. The gas freed from the suspended particles flows off at G, the valuable dust collects in the funnel 7.

Da es unwirtschaftlich wäre, einen Kessel in der Betriebsperiode eines einzigen Konverters zu beheizen, werden die Gase der ganzen Anlage, also mehrere Konverter, abwechselnd in die Flammrohre geleitet. Zu diesem Zweck ist eine geineinsaine Sammelleitung 8 vorgesehen, in die die Hauben 2 der Konverteranlage einmünden, derart, daß die Abgase einer ganzen Gruppe von Konvertern in der Reihenfolge ihres Betriebes abwechselnd in die Flammrohre 3 gelangen.Since it would be uneconomical to use a boiler during the operating period of a To heat a single converter, the gases from the entire system, i.e. several Converter, fed alternately into the flame tubes. For this purpose it is a single one Collecting line 8 is provided, into which the hoods 2 of the converter system open, in such a way that the exhaust gases of a whole group of converters in the order of their operation alternately get into the flame tubes 3.
