Description

Verfahren zur Verhütung:von Schlotbränden bei elektrischen Gasreinigern. Bei Schloten, durch die Rauchgase oder sonstige Gase geführt werden, welche brennbaren Staub enthalten, liegt Brandgefahr vor, indem sich der niedergeschlagene Staub entzünden kann. Die elektrische Gasreinigung ist daher für solche Gase besonders gefährlich.Methods to prevent: Chimney fires with electric gas cleaners. For chimneys through which flue gases or other gases are passed, which are combustible Contain dust, there is a fire hazard in that the deposited dust ignites can. Electrical gas cleaning is therefore particularly dangerous for such gases.

Durch vorliegende Erfindung soll jede Brandgefahr dadurch unschädlich gemacht werden, daß bei eintretender Brandgefahr so viel Feuchtigkeit, zweckmäßig in Form von Dampf, zugeführt wird, daß eine Entzündung nicht eintreten kann. Bei Braunkohlentrockenanlagen genügt es beispielsweise, die Gase um a5 bis 30° abzukühlen, um eine Wasserbildung zu erreichen. Dies kann durch Zusetzen kalter Luft erreicht werden. Das Üffnen dieser Luftschieber kann automatisch erfolgen, indem etwa eine in der Niederschlagskammer auftretende Temperatursteigerung oder die Veränderung der Stromstärke oder Spannung dazu benutzt wird, die Betätigung der Luftschieber oder Dampfventile zu bewirken. Es ist schon vorgeschlagen, dauernd eine- Unterkühlung und eine Übersättigung der Gase mit Feuchtigkeit (Dämpfen) anzuwenden; dieses Mittel würde aber versagen, weil dadurch die Anlage nicht mehr betriebsfähig wäre; die Kammer würde sich dann ganz mit Staub zusetzen, und es würde erst recht Brand eintreten. Dagegen schadet die vorübergehende Sättigung nichts, weil der Staub schnell wieder trocken wird und dann abfällt.The present invention is intended to render any fire hazard harmless be made that if there is a risk of fire so much moisture, expedient in the form of steam is supplied so that ignition cannot occur. at Lignite drying plants, for example, it is sufficient to cool the gases by a5 to 30 °, to achieve water formation. This can be achieved by adding cold air will. The opening of this air slide can be done automatically, for example by using a Temperature rise or change occurring in the precipitation chamber the current or voltage is used to actuate the air slide or to effect steam valves. It has already been suggested that there should be constant hypothermia and to apply a supersaturation of the gases with moisture (vapors); this means but would fail because the system would no longer be operational as a result; the The chamber would then become completely clogged with dust, and a fire would break out even more. On the other hand, the temporary saturation does no harm because the dust quickly returns gets dry and then falls off.
