Abstract

A process for treating pollutants in electrofilter systems (DE19841311.4) comprises directing ions (3) produced by a spray electrode (2) in the direction of a highly conducting material (4). The pollutants have ions covering them, and form a coating on the pptn electrodes. The latter consist of pins and are porous.

Description

Es ist bekannt, daß Elektrofilter mit einer denaturierenden Niederschlagselektrode ausgerüstet werden.It is known that electrostatic precipitators are equipped with a denaturing precipitation electrode become.

Hierbei ist die Niederschlagselektrodenoberfläche denaturierend wirkend d. h. stark alkalisch und/oder sauer bzw. in abwechselnder Folge angeordnet, wobei der Niederschlagselektro­ den-Belag den pH-Wert vorzugsweise um 14 und/oder 2 aufweist. In der Hauptanmeldung 198 41 ­ 311.4 vom 10.09.98 ist eine Ionenquelle beschrieben, die eine möglichst hohe Ergiebigkeit an Ionen gewährleistet. Damit die erzeugten Ionen auch bestmöglich in der gewünschten Abscheidetechnik genutzt werden, werden nachfolgende erfindungsgemäße Verbesserungen der Niederschlagselektrode vorgeschlagen.The precipitation electrode surface has a denaturing effect d. H. strongly alkaline and / or acidic or arranged in an alternating sequence, the precipitation electrode the coating preferably has a pH of around 14 and / or 2. In the main application 198 41 311.4 dated 09/10/98 describes an ion source that offers the highest possible productivity Ions guaranteed. So that the ions generated are also in the desired form Deposition technology are used, the following improvements according to the invention the precipitation electrode is proposed.

In der beiliegenden Skizze ist eine solche erfindungsgemäße Niederschlagselektrode dargestellt. Diese Niederschlagselektrode weist eine lochartige Oberfläche auf, wobei diese lochartige Oberfläche Löcher aufweist, die vorzugsweise mit leitfähigen Stiften versehen sind:
1 der Luftstrom
2 die Sprühelektrode
3 die Ionen
4 die Niederschlagselektrode die aus Metall besteht oder aus einem sonstigen, vorzugsweise gesteiften, elektrisch leitenden Material
5 der Niederschlagselektrodenbelag der stark alkalisch und/oder sauer ausgebildet ist
6 Lochanordnungen, die vorzugsweise mit Stiften selbst versehen sind
7 elektrisch leitfähige StifteSuch a precipitation electrode according to the invention is shown in the attached sketch. This precipitation electrode has a hole-like surface, this hole-like surface having holes which are preferably provided with conductive pins:
1 the airflow
2 the spray electrode
3 the ions
4 the precipitation electrode, which consists of metal or of another, preferably stiffened, electrically conductive material
5 the precipitation electrode coating which is strongly alkaline and / or acidic
6 hole arrangements, which are preferably provided with pins themselves
7 electrically conductive pins

Die elektrisch leitfähigen Stifte können auch auf der Niederschlagselektrode (4) aufgesteckt sein, so daß sie mit dem Belag (5) verbunden eine elektrisch leitfähige Verbindung ergeben, so daß bei der Ionenwanderung von der Sprühelektrode (2) zum Niederschlagselektrodenbelag (5) diese Leitstifte die Ionen auf dem kürzesten Weg zur hochleitfähigen Basiselektrode (4) führen, so daß erfindungsgemäß die Ionen, die Schadstoffe zur Niederschlagselektrode transportieren, über die Leitstifte (7) die Ladung abgeben und im Bereich der belegenden Masse (5) im Bereich der Löcher, die Schadstoffe sich ablagern.The electrically conductive pins can be pushed onto the collecting electrode (4) so that it is connected to the pad (5) provide an electrically conductive connection, so that when the ion migration from the discharge electrode (2) to the precipitation electrode pad (5), these guide pins, the Ions lead the shortest way to the highly conductive base electrode ( 4 ), so that according to the invention the ions that transport pollutants to the precipitation electrode release the charge via the guide pins ( 7 ) and the pollutants in the area of the covering mass ( 5 ) in the area of the holes settle down.

Erfindungsgemäß soll die Niederschlagselektrodenbelegung großporig sein, das ist auch unter Löcher zu verstehen, das die feinen Nadelspitzen, die entweder zur metallischen Niederschlagselektrode (4) oder Leitelektrode (4) gehören, mit der Belegung (5) in Verbindung stehen, wobei diese Belegung erfindungsgemäß auch wieder feine Leitstifte aufweisen kann, die in den großporigen Auflagen, z. B. bestehend aus Vlies, was sehr stark porös ist, staubförmige und auch andere Ablagerungen denaturierend ein und/oder umschlossen werden.According to the invention the precipitation electrode occupancy should be large pores, which is also to be understood under the holes, which are fine needle points which belong to either the metallic precipitation electrode (4) or lead electrode (4) with the assignment (5) in the compound, said assignment according to the invention also can again have fine guide pins, which in the large-pore editions, for. B. consisting of fleece, which is very porous, dusty and other deposits denaturing and / or enclosed.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen ausgebildeten und dargestellten Formen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, daß die Niederschlagselektrode (4) selbst oder die Auflage (5) Niederschlagselektrode großporig leitend ausgebildet ist, wobei vorzugsweise in der Großporigkeit, den sog. Löchern Leitstifte noch eingesetzt sind, die eine Verbesserung der Leitfähigkeit der Ionen von der Oberfläche (5) zur Niederschlagselektrode (4) ermöglichen und somit die Schadstoffe die mit Ionen geladen sind, sich in diesem Niederschlagsmedium ablagern und/oder einschließen, so daß der denaturierende Effekt gegeben ist.Of course, the invention is not limited to the forms specifically described and shown above, but numerous modifications are possible without, however, deviating from the basic idea that the precipitation electrode ( 4 ) itself or the support ( 5 ) precipitation electrode is large-pored, whereby Preferably, the large pores, the so-called holes, guide pins are still used, which improve the conductivity of the ions from the surface ( 5 ) to the precipitation electrode ( 4 ) and thus the pollutants loaded with ions are deposited in this precipitation medium and / or include so that the denaturing effect is given.
