Description

Verfahren Betrieb elektrischer Gasreiniger. Bei elektrischen Gasreinigern bereitet es bei manchen Materialien Schwierigkeiten, den abgeschiedenen Staub zu entfernen. Versuche haben gezeigt, daß das Haften außer auf Adhäsion auch auf Elektronenaufprall zurückzuführen ist. Schaltet man den Strom einen kurzen Augenblick aus, hierfür genügen bei den üblichen Staubgrößen und Staubsorten in der Regel 1/ü bis 5 Sekunden, so fällt das Material ab. Dies beruht auf einemandern Vorgang als das beim Abscheiden des Staubes aus Gasen mittels magnetisierter Flächen übliche zeitweilige Ausschalten des Magnetisierungsstromes und war nicht ohne weiteres vorauszüseh en.Method of operation of electric gas purifiers. With electric gas cleaners it is difficult for some materials to prepare the separated dust remove. Experiments have shown that sticking is not only due to adhesion but also to electron impact is due. If you switch off the power for a short moment, this is the case With the usual sizes and types of dust, 1 / g to 5 seconds are usually sufficient, so the material falls off. This is due to a different process than that of the deposition the usual temporary switch-off of dust from gases by means of magnetized surfaces of the magnetizing current and could not be easily predicted.

Danach ergibt sich für das Verfahren der elektrischen Gasreinigung zweckmäßig die Durchführung in'der Weise, daß während des Gasdurchganges der elektrische Strom in gewissen Zeitabständen -je für eine kurze Zeitspanne ausgeschaltet wird.This results in the process of electrical gas cleaning expediently the implementation in the way that during the passage of gas the electrical Electricity is switched off at certain time intervals - each for a short period of time.

Da die Durchgangszeit des Gases durch den Gasreiniger wesentlich länger ist als die zum Abfallen benötigte Zeit der Stromlosigkeit beträgt, so erhellt daraus, daß diese kurzen Ausschaltungen die Stetigkeit der Gasreinigung nicht beeinträchtigen.Since the passage time of the gas through the gas cleaner is much longer is than the time required for the fall to be in the absence of electricity, it is evident from this, that these short switch-offs do not affect the continuity of the gas cleaning.
