Description

Gaswechseleinrichtung für Regenerativkoksöfen u. dgl. Bei Regenerativfeuerungen, insbesondere bei den große Regeneratorräutne aufweisenden Regenerativkoksöfen, ist es von Belang, rlaß bei dein Beheizungswechsel zuerst das Gas von rlei einen Brennerreihe abgesperrt, hierauf der Zugwechsel der Verbrennungsluft bewirkt und dann erst, d.li. erst nach einigen Minuten, der Gasdurchlaf) zur anderen Brennerreihe geöffnet wird, damit die Verbrennungsluft zuerst die in den letzt beheizten Regeneratoren noch vorhandenen Rauchgase ausspült, ehe zu der Verbrennungsluft )las Heizgas tritt, welches sonst innerhalb jenes Ratieligasgeniisclie, unverbrannt entweichen würde. Dementsprechend soll gemäß der Erfindung bei den für Ga,wechseleinrichtungen bekannten Dreiweghähnen nie Kükenbohrung und der Kükenumfang im Verhältnis zu einander derart bemessen werden, rlaß innerhalb des üblichen Drehwinkel, beide Abzweigleitungen während eines Teiles dieser Drehung geschlossen sind.Gas exchange device for regenerative coke ovens and the like. especially in the regenerative coke ovens with large regenerator lines It is important to first let out the gas from one row of burners when you change the heating locked, thereupon the change in draft of the combustion air is effected and only then, d.li. only after a few minutes, the gas passage) to the other row of burners is opened, so that the combustion air is first in the last heated regenerators flushes out existing flue gases before the heating gas enters the combustion air, which otherwise would escape unburned within that ratio league genius. Accordingly, according to the invention in the known for Ga, changing devices Three-way taps never have plug bore and the plug size in relation to each other in such a way be dimensioned within the usual angle of rotation, both branch lines are closed during part of this rotation.

Die Zeichnung veranschaulicht eine Ausführungsform der Gaswechseleinrichtung in Abb. i und 2 in einem Querschnitt bei zwei verschiedenen Kükenstellungen und in Abb.3 in einem 1.äilgssclinitt: Abb.4 zeigt die Gruppenschaltung der Hähne.The drawing illustrates an embodiment of the gas exchange device in Fig. i and 2 in a cross section with two different chick positions and in Fig.3 in a 1.äilgssclinitt: Fig.4 shows the group connection of the taps.

Der zur Vornahme des Gaswechsels die-. nende Dreiwegliahn Ir. weist ein Küken h mit einer beispielsweise winkligen Bohrung i. auf, so daß in diesem Fall der Hahn kopfseitig auf die Hauptleitung a gesetzt werden kann.The one to carry out the gas change. end three-way liaison Ir. has a plug h with an, for example, angled bore i. so that in this case the cock can be placed on the main line a at the head.

tels eines Hebels d o. dgl. sind die Hähne h in üblicher Weise an den Seilstrang e= der Umstellwinde angeschlossen. Der Durchmesser der Kiikenhohrung i und der Umfang des Kükens k sind nun im Verhältnis zueinander so bemessen, daß während eines Teiles der Drehung des Kükens von der einen zur anderen Endstellung beide Abzweigleitungen b, c geschlossen sind, also, wie Abb. i und 2 veranschaulichen, bei einer Kükendrehung von beispielsweise 9& die Abzweigleitungen während einer Kükendrehung von beispielsweise n.3° geschlossen sind. Dies genügt, um zu bewirken, daß die Gaszuführung während einer hinreichend langen Dauer zwischen dem Zugwechsel der Verbrennungsluft aussetzt.by means of a lever d or the like. The taps h are on in the usual way connected to the cable line e = of the converting winch. The diameter of the kiiken hole i and the circumference of the plug k are now dimensioned in relation to one another so that during part of the rotation of the plug from one end position to the other both branch lines b, c are closed, i.e., as illustrated in Figs. i and 2, with a plug rotation of e.g. 9 & the branch lines during a Chick rotation of, for example, n.3 ° are closed. This is enough to cause that the gas supply for a sufficiently long period between the train change exposed to combustion air.

Es wird mithin jene, mit Unterbrechung wirkende Art der Gasumstellung auf eine sehr einfache Weise erzielt, und hiermit zugleich der bekannte Vorteil von Dreiweghähnen für den vorliegenden Zweck, nämlich rles Fortfalls der Hälfte der Gashähne, vereinigt, und dies beides, ohne daß die L`mstellweglänge sich vergriißert oder, wie bei Vorrichtungen anderer Art, in einem Teil der Umstellvorrichtung ein Stillstand während des Umstellen, eintreten muß.It will therefore be the type of gas switch that has an intermittent effect achieved in a very simple way, and at the same time the well-known advantage of three-way faucets for the present purpose, namely rles loss of half of the gas taps, combined, and both without increasing the length of the adjustment path or, as with devices of other types, in a part of the changeover device Standstill during the changeover, must occur.

PATENT-ANSPRUCH: Aus einem Dreiwegljahn bestehende Gaswechseleinrichtung für Regenerativkoksöfen u. dgl., dadurch gekennzeichnet, rlaß die Kükenbohrung und der Kükenunifang des Hahnes im Verhältnis zueinander derart bemessen sind, daß während eines Teiles der Drehung des Kükens von der einen zur anderen Endstellung beide Abzweigleitungen geschlossen sind, so daß die Gaszufuhr zwischen dem Zugwechsel der Verbrennungsluft ohne einen Stillstand in der Umstellvorrichtung aussetzt. PATENT CLAIM: A gas exchange device for regenerative coke ovens and the like consisting of a three-way valve, characterized in that the plug bore and the plug ring of the plug are dimensioned in relation to one another in such a way that during part of the rotation of the plug from one end position to the other, both branch lines are closed, so that the gas supply is interrupted between the change in drafts of the combustion air without a standstill in the changeover device.
