Abstract

The ionizer provides electrical charging of solid or liquid particles contained in the air via a number of spray electrode wires (4), extending parallel to one another perpendicular to the air flow direction, with sheet metal walls (1) between them defining air flow channels, each having a spray electrode at its center. The opposing sheet metal walls are bent outwards to form a widened channel section on one side of each spray electrode wire.

Description

Die Erfindung betrifft einen lonisator für ein Filtergerät, bei dem im lonisator die im Gas insbesondere in der Luft enthaltenen festen oder flüssigen Teilchen elektrisch aufgeladen werden, um danach zwischen den Platten eines Kollektors abgeschieden zu werden, wobei im lonisator mehrere Sprühelektroden-Drähte zueinander parallel und quer zum Strom des Gases/der Luft gespannt und zwischen den Sprühelektroden-Drähten Blechwände angeordnet sind, die Gas/Luftkanäle bilden, zwischen denen mittig die Sprühelektroden-Drähte angeordnet sind.The invention relates to an ionizer for a filter device, in which the solid or liquid particles contained in the gas, especially in the air to be electrically charged to thereafter between the plates of a collector to be deposited, with several spray electrode wires in the ionizer stretched parallel to each other and across the flow of gas / air and Sheet metal walls are arranged between the spray electrode wires, the gas / air channels form, between which the spray electrode wires in the middle are arranged.

Bei einem solchen lonisator eines Filtergerätes ist es bekannt, dass mehrere Blechwände in gleichen Abständen parallel nebeneinander in Richtung des Gasstromes angeordnet sind und jeweils zwischen zwei Blechwänden mittig eine meist drahtförmige Sprühelektrode befestigt ist, die parallel zu den geerdeten Blechwänden und rechtwinklig zur Strömungsrichtung des Gasstromes gespannt ist. Bei dieser bekannten Konstruktion strömt das Gas mit gleichbleibender Geschwindigkeit durch den Kanal zwischen den Blechwänden und kommt nur kurzzeitig und mit zunehmender Stärke und danach wieder abnehmender Stärke in den Behandlungsbereich der Sprühelektrode.With such a lonizer of a filter device, it is known that several Sheet metal walls at equal intervals parallel to each other in the direction of Gas flow are arranged and one in the middle between two sheet metal walls mostly wire-shaped spray electrode is attached, which is parallel to the grounded Sheet metal walls and stretched at right angles to the direction of flow of the gas stream is. In this known construction, the gas flows with a constant Speed through the channel between the sheet metal walls and only comes briefly and with increasing strength and then decreasing strength in the treatment area of the spray electrode.

Aufgabe der Erfindung ist es, einen lonisator der eingangs genannten Art so zu verbessern, dass das Gas durch die Sprühelektrode gleichmäßiger und zeitlich länger behandelt wird. The object of the invention is to provide an ionizer of the type mentioned at the beginning improve the gas through the spray electrode more evenly and temporally is treated longer.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zumindest eine Blechwand (1), insbesondere die zwei Blechwände zu beiden Seiten eines Sprühelektroden-Drahtes jeweils eine Erweiterung aufweisen, die eine Gesamterweiterung des Kanals bilden.This object is achieved in that at least one Sheet metal wall (1), in particular the two sheet metal walls on either side of one Spray electrode wire each have an extension, the one Form the overall expansion of the canal.

Die Blechwände bilden damit im Bereich der Sprühelektrode eine Gesamterweiterung des Kanals ohne dass die Blechwände im Eingangs- und Ausgangsbereich einen größeren Abstand besitzen müssen, so dass die Anzahl der Blechwände gleichbleiben kann. Die jeweilige Gesamterweiterung eines Kanals im Bereich einer Sprühelektrode führt innerhalb dieses Bereiches zu einer Verlangsamung des Gasstromes, so dass das Gas im Bereich der Elektrode länger verweilt und damit dort stärker ionisiert wird, ohne die Geschwindigkeit des Gasstromes vor und hinter dem lonisator verlangsamen zu müssen. Darüber hinaus wird im Bereich der Kanalerweiterung eine gleichmäßige gekrümmte Strömung zu beiden Seiten um die drahtförmige Sprühelektrode erreicht, so dass es zusätzlich zu einer Vergleichsmäßigung der Behandlung kommt. Alternativ kann aber auch die Geschwindigkeit des Gasstromes vor und hinter der Erweiterung vergrößert werden, so daß der Durchsatz durch den lonisator erhöht wird.The sheet metal walls thus form one in the area of the spray electrode Overall expansion of the channel without the sheet metal walls in the entrance and Exit area must have a larger distance, so the number the sheet metal walls can remain the same. The respective overall extension of a Channel in the area of a spray electrode leads to a within this area Slowing down the gas flow so that the gas in the area of the electrode lingers longer and is ionized there more without speed to slow down the gas flow in front of and behind the ionizer. About that In addition, in the area of the channel expansion, a uniform curved Flow reached on both sides around the wire-shaped spray electrode, so that treatment is evened out more evenly. alternative but can also the speed of the gas flow before and after the Expansion can be increased so that the throughput through the ionizer increases becomes.

Es ist besonders vorteilhaft, wenn die Erweiterung eine teilzylindrische, zur Sprühelektrode parallele Auswölbung ist, deren Wandabstand zur Sprühelektrode, insbesondere zum Sprühelektrodendraht oder zur Kante eines Sprühelektrodenbleches jeweils gleichbleibend ist. Ferner wird vorteilhafterweise vorgeschlagen, dass die beiden Erweiterungen beider Kanalwände einander unversetzt gegenüber liegen.It is particularly advantageous if the extension is a partially cylindrical one Spray electrode is parallel bulge, the wall distance to Spray electrode, in particular to the spray electrode wire or to the edge of a Spray electrode sheet is constant in each case. It is also advantageous suggested that the two extensions of both channel walls meet each other lie opposite one another.

Eine platzsparende Bauweise und damit ein verhältnismäßig enges Anordnen der Blechwände zueinander, wobei dennoch ausreichend breite Gesamterweiterungen erreicht werden, wird dann erzielt, wenn die Blechwände in einem zur Sprühelektrode lotrechten Querschnitt S-förmig sind, und eine Hälfte der S-Form zusammen mit einem auf einer ersten Seite benachbarten Blechwände eine Gesamterweiterung und die andere Hälfte der S-Form zusammen mit einem auf der anderen Seite benachbarten Blechwände eine weitere Gesamterweiterung des Kanals bildet.A space-saving design and thus a relatively tight arrangement the sheet metal walls to each other, but still sufficiently wide Overall expansions are achieved when the sheet metal walls are S-shaped in a cross section perpendicular to the spray electrode, and one half the S shape together with one adjacent on a first side Sheet metal walls an overall extension and the other half of the S shape together with a sheet metal wall adjacent on the other side further overall expansion of the channel forms.

Vorzugsweise wird vorgeschlagen, dass jede Blechwand zu beiden Seiten der S-Form einen ebenen Endwandbereich bildet, der parallel zur Gas/Luftströmungsrichtung ist und den Ein- oder Auslassbereich für das Gas/die Luft bildet. Dies führt zu einer einfachen Befestigung der Blechwände. Hierbei wird vorgeschlagen, dass durch die Endwandbereiche Stäbe quer zur Strömungsrichtung zur Befestigung der Blechwände (1) verlaufen.It is preferably proposed that each sheet metal wall on both sides of the S shape forms a flat end wall area that is parallel to the gas / air flow direction and the inlet or outlet area for the gas / air forms. This leads to a simple fastening of the sheet metal walls. Here will suggested that through the end wall areas bars across Flow direction for fastening the sheet metal walls (1).

In Strömungsrichtung 2 vor oder hinter der Gesamterweiterung 8 bilden die Blechwände im Kanal eine Gesamtverengung 9 durch die jeweiligen Verengungen 7 der Blechwände 1.In the flow direction 2 upstream or downstream of the overall expansion 8 Sheet metal walls in the channel an overall narrowing 9 by the respective Narrowing 7 of the sheet metal walls 1.

Die Kanalgesamterweiterung 8 vergrößert die normale Kanalbreite B um das 1,5-fache, wobei die Kanalbreite im Bereich der Verengung die halbe normale Kanalbreite B beträgt.The overall channel extension 8 increases the normal channel width B by 1.5 times, the channel width in the area of the constriction is half the normal Channel width B is.
