Description

Elektrofilter, insbesondere für Rauchgase Bei Elektrofiltern tritt häufig die Aufgabe auf, die Gasreinigungskammern so atiszubilden, daß der Außenumfang der Kammern möglichst klein ist und dabei doch der größte Teil des Kammerquerschnitts für das elektrische Sprühfeld ausgenutzt wird, um so eine möglichst gute Niederschlagswirkung zu erzielen. Im folgenden wird nun eine besonders für Rauchgase und ähnliche Abgase geeignete Filterbauart gezeigt, die den angegebenen Erfordernissein Rechnung trägt.Electrostatic precipitator, especially for flue gases often the task of so atiszubilden the gas cleaning chambers that the outer circumference of the chambers is as small as possible and yet the largest part of the chamber cross-section is used for the electrical spray field in order to achieve the best possible precipitation effect to achieve. The following is a special one for flue gases and similar exhaust gases suitable filter design shown, which takes the specified requirements into account.

Erfindungsgemäß ist das Elektrofilter so ausgebildet, daß die Elektroden etwa den Querschnitt eines auf eine- Spitze gestellten Rhombus besitzen und in einem Gaskanal von gleicher Ouerschnittsform angeordnet sind. Diese Ausbildung des Filters hat den großen Vorteil, daß fast der gesamte Querschnitt des Kanals für das Sprühfeld ausgenutzt wird. Die Sprühelektroden werden dabei vorteilhaft an den beiden stumpfwinkeligen Ecken aufgehängt. Es lassen sich dann die Tragisolatoren für die Sprühelektroden in räumlich besonders günstiger Weise an dem Filter anordnen.According to the invention, the electrostatic precipitator is designed so that the electrodes have approximately the cross-section of a rhombus placed on a point and in one Gas channel are arranged from the same cross-sectional shape. This training of the filter has the great advantage that almost the entire cross-section of the channel for the spray field is exploited. The spray electrodes are advantageously on the two obtuse-angled Hung corners. The support insulators for the spray electrodes can then be removed arrange in a spatially particularly favorable manner on the filter.

In der Figur ist ein Ausführungsbeispiel hierfür im Querschnitt dargestellt. 21 ist der zur Abführung der Gase dienende Kanal, der einen rhombusartigen Ouersclinitt besitzt. In diesem Kanal sind die Sprüh- und Niederschlagselektroden 22 und 23 von ähnlicher rhombischer Gestalt aufgehängt. Die Sprühelektroden 22 sind an den beiden seitlichen Kanten mittels der Tragstangen 2.4 und 25 an den beiden Tragisolatoren 26 und 27 befestigt, die auf die Nebenkammern 28 und 29 aufgesetzt sind. Die zu reinigenden Gase gehen in der Pfeilrichtung durch das Filter hindurch und werden vor dem Eintritt in das Sprühfeld durch die dort angebrachten Drosselbleche 39 gleichmäßig über den Kammerquerschnitt verteilt. An der tiefsten Stelle des Kanals ist eine Transportschnecke 31 angebracht, welche das Niederschlagsgut abführt.In the figure, an embodiment for this is shown in cross section. 21 is the channel used to discharge the gases, which has a rhombus-like Ouersclinitt. The spray and precipitation electrodes 22 and 23 of a similar rhombic shape are suspended in this channel. The spray electrodes 22 are fastened at the two lateral edges by means of the support rods 2.4 and 25 to the two support insulators 26 and 27, which are placed on the secondary chambers 28 and 29. The gases to be cleaned pass through the filter in the direction of the arrow and are evenly distributed over the cross section of the chamber by the throttle plates 39 attached there before entering the spray field. At the lowest point of the channel, a screw conveyor 31 is attached, which removes the precipitation.
