Description
Elektrofilter. Die seit langem bekannten Elektrofilter bestehen aus einem System von negativ gela denen Drahtelektroden und parallel dazu laufenden flächenhaften, geerdeten Ab scheideelektroden. Letztere weisen die Form von zu den Drahtelektroden koaxialen Roh ren, oder von Platten oder Wellblechen auf. Auch sind sie in Form von Drahtnetzen be kannt.
Gegenstand vorliegender Erfindung ist ein Elektrofilter mit stabförmigen Abscheide- elektroden, die para'll'el zu den Sprühelektro den angeordnet sind und deren Durchmesser wenigstens so gross ist, dass sie bei der be triebsmässigen Spannung keine Glimmentla- dung aufweisen. Wenn die stabförmigen Ab scheideelektroden als Rohre ausgebildet sind, können sie verhältnismässig dünnwandig und doch mechanisch stabil sein, so dass sie leicht und billig sind.
Sie erlauben weitgehende Freiheit in der Wahl des Materials, da sich Rohre und Stangen aus verschiedensten Me tallen, ferner aus Graphit, metallisiertem Hol z, metallisiertem Porzelle,n, Eisenhydrogyd herstellen lassen, so dass leicht Filter für che misch stark aktive Stoffe gebaut werden können.
Eine Besonderheit rohrförmiger Elektro den ist die Möglichkeit, sie zur Heizung oder Kühlung des Filterraumes heranzuziehen, indem eine warme oder kalte Flüssigkeit oder ein Gas durchgeleitet wird. Insbesondere be wirkt die :Kühlung eine Kondensation von Gasen zu Dämpfen. Dies isst von Bedeutung, da Gase nicht abgeschieden werden können, wohl aber Dämpfe.
Die Kapazität solcher Filter kann bei gleicher Leistungsfähigkeit kleiner als die jenige der bekannten Platten- und Rohrfilter sein, was bei Anwendung pulsierender Gleich spannung eine geringere Strombelastung be wirkt.
Die gegenseitige Anordnung der Elektro den geht aus den Fig. 1 und 2 hervor, wel che zwei Beispiele von Querschnitten durch das Elektrodensystem zeigen. 1 sind die ne gativen Drahtelektroden, 2 die Stab- oder Rohrelektroden.
Electrostatic precipitator. The long-known electrostatic precipitators consist of a system of negatively charged wire electrodes and parallel, planar, grounded separating electrodes. The latter are in the form of tubes coaxial with the wire electrodes, or of plates or corrugated sheets. They are also known in the form of wire nets.
The subject of the present invention is an electrostatic precipitator with rod-shaped separation electrodes which are arranged parallel to the spray electrodes and whose diameter is at least so large that they do not have a glow discharge at the operational voltage. If the rod-shaped separating electrodes are designed as tubes, they can be relatively thin-walled and yet mechanically stable, so that they are light and cheap.
They allow extensive freedom in the choice of material, since tubes and rods can be made from a wide variety of metals, graphite, metallized wood, metallized porcelain, iron, and iron, so that filters for chemically highly active substances can easily be built .
A special feature of tubular electrodes is that they can be used to heat or cool the filter chamber by passing a warm or cold liquid or gas through. In particular, the following effects: cooling condensation of gases to vapors. This is important because gases cannot be separated, but vapors can.
The capacity of such filters can be smaller than those of the known plate and tube filters with the same performance, which affects a lower current load when using pulsating DC voltage.
The mutual arrangement of the electrodes is apparent from FIGS. 1 and 2, wel che show two examples of cross sections through the electrode system. 1 are the negative wire electrodes, 2 are the rod or tube electrodes.
