Description

Anordnung zur Verminderung der Dämpfurig: der bei der elektrischen Reinigung von Gasen nach Patent 638 700 si@rgebenden Spannungsstöße In dem Patent 64o 003 ist eine Anordnung zur Verminderung der Dämpfung der Spannungsstöße angegeben, die bei der elektrischen Reinigung von Gasen nach Patent 638 700 auftreten. Diese, insbesondere für größere Filteranlagen geeignete Anordnung besteht darin, daß die Sprühelektroden in mehrere kleinere Kapazitäten unterteilt sind, die abwechselnd nacheinander an den Stoßspannungsstromkreis angeschlossen werden. Dadurch wird erreicht, daß eine nur geringe Dämpfung der Spannungsstöße eintritt. Im folgenden wird nun eine Anordnung gezeigt, die in besonders vorteilhafter Weise zur Verminderung der Dämpfung der Spannungsstöße beiträgt.Arrangement to reduce the attenuation: that of the electrical Purification of gases according to patent 638 700 safe voltage surges In the patent 64o 003 an arrangement for reducing the damping of voltage surges is given, which occur in the electrical cleaning of gases according to patent 638 700. These, Particularly suitable for larger filter systems arrangement is that the Spray electrodes are divided into several smaller capacities, which alternate connected one after the other to the surge voltage circuit. This achieves that there is only a slight attenuation of the voltage surges. The following is now an arrangement shown in a particularly advantageous manner to reduce the Contributes to damping the voltage surges.

Erfindungsgemäß ist die Anordnung so getroffen, daß der abwechselnde Anschluß der Elektrofilterteilkapazitäten an den Stoßspannungsstromkreis unter Vermeidung rotierender Teile über je eine Stoßfunkenstrecke und diesen vorgeschaltete, entsprechend abgestimmte Ohmsche oder induktive Widerstände erfolgt. Die erste unverzögerte Funkenstrecke spricht dann zuerst an, darauf folgt die nächste etwas verzögerte Funkenstrecke usw., bis alle Funkenstrecken angesprochen haben. Inzwischen ist die Entladung in dem ersten Sprühfeld so weit vor sich gegangen, daß die erste Funkenstrecke wieder ansprechen und damit das Spiel von neuem beginnen kann.According to the invention, the arrangement is made so that the alternating Connection of the electrostatic precipitator partial capacities to the surge voltage circuit, avoiding them rotating parts via an impulse spark gap each and which is connected upstream accordingly Matched ohmic or inductive resistances are made. The first instant spark gap then responds first, followed by the next somewhat delayed spark gap etc., until all spark gaps have responded. Meanwhile the discharge is in the first spray field has gone so far that the first spark gap again address and so that the game can start all over again.

In der Figur ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. i ist ein an das Leitungsnetz angeschalteter Spannungswandler, der die notwendige Hochspannung erzeugt. Das eine Ende der Sekundärspule ist geerdet, das andere über den Gleichrichter 2 geführt und dann in die drei Leitungen 3, 4, 5 abgezweigt, die zu den Sprühelektroden der drei Sprühfelder 6, 7 und 8 geführt sind. Vor der Abzweigstelle ist noch ein großer Kondensator 9 angeordnet, dessen eine Belegung geerdet ist. In die drei Abzweigleitungen 3, 4, 5 sind nun die Stoßfunkenstrecken io, 1i, 1z eingeschaltet, vor denen die geerdeten Stoßkondensatoren 13, 14, 15 vorgesehen sind. Vor diesen Stoßkondensatoren sind in die drei Abzweigleitungen ferner die Widerstände 16, 17 und i8 in die Leitungen eingeschaltet, die derart verschieden bemessen sind, daß die Stoßfunkenstrecken io, 1i, 1z in verschiedenen zeitlichen Abständen ansprechen. Auf diese Weise wird, ohne daß bewegte Teile, wie z. B. rotierende Schalter, benutzt werden müssen, erreicht, daß man mit nur einem verhältnisinäßig kleinen Hochspannungserzeuger mehrere Sprühfelder mit kurzzeitigen Stoßspannungen speisen kann.An exemplary embodiment of the invention is shown schematically in the figure shown. i is a voltage converter connected to the line network, the generates the necessary high voltage. One end of the secondary coil is grounded, the other passed through the rectifier 2 and then into the three lines 3, 4, 5 branched off, which led to the spray electrodes of the three spray fields 6, 7 and 8 are. In front of the branch point, a large capacitor 9 is also arranged, its an occupancy is grounded. The surge spark gaps are now in the three branch lines 3, 4, 5 io, 1i, 1z switched on, in front of which the grounded surge capacitors 13, 14, 15 are provided are. In front of these surge capacitors there are also the three branch lines Resistors 16, 17 and i8 are switched into the lines that are so different are dimensioned that the impulse spark gaps io, 1i, 1z in different time Address at intervals. In this way, without moving parts such. B. rotating Switches that have to be used achieve that you can use only one proportionately small high voltage generator several spray fields with short-term surge voltages can dine.
