Description

Die Erfindung betrifft ein Ionisationsfilter zur Luftreinigung.The invention relates to an ionization filter for air purification.

Es ist bekannt, Ionisationsabscheider zur Luftreinigung für verschiedenste Zwecke zu verwenden.It is known to use ionization separators for air purification for various purposes use.

Weiterhin ist bekannt, daß diese Filter gegenüber den anderen Filtern viele Vorteile besitzen wie zum Beispiel einen niedrigen Druckverlust.It is also known that these filters have many advantages over the other filters have, for example, a low pressure drop.

Normale Filter wie Vliese usw. haben die ganz große Schwierigkeit, daß der Druckverlust so hoch ist und die Kanäle nicht so dicht ausgebildet sind, daß selbst bei erhöhtem Ventilatordruck Undichtigkeiten an den Verbindungsstellen entstehen und somit unkontrolliert Bakterien, Vieren, Keime usw. durch zum Beispiel Krankenhausgebäude und Arbeitsgebäude gedrückt werden.Normal filters such as fleeces etc. have the great difficulty that the Pressure loss is so high and the channels are not so dense that even with increased fan pressure, leaks occur at the connection points and thus uncontrolled bacteria, fours, germs etc. by, for example Hospital building and work building are pressed.

In verschiedenen Ausgestaltungsmöglichkeiten können die Niederschlagselektroden dieser bekannten Abscheider auch zusätzlich als Filter ausgebildet sein.The precipitation electrodes can be designed in different ways this known separator can also be designed as a filter.

Ein großer Nachteil besteht aber darin, daß die dort angesammelten Bakterien, Pilze, Sporen oder allgemein Mikroorganismen mit dem sich ebenfalls dort abgeschiedenen Staub als Nährboden leicht weiterexistieren und sich vermehren können.A big disadvantage is that the bacteria, fungi, Spores or microorganisms in general with the also deposited there Dust can easily continue to exist as a breeding ground and multiply.

Es ist Aufgabe der Erfindung, diesen Nachteil zu vermeiden.It is an object of the invention to avoid this disadvantage.

Zur Lösung dieser Aufgabe wird ein Ionisationsfilter zur Luftreinigung vorgeschlagen, bei dem die Niederschlagselektrode mit denaturierenden Eigenschaften ausgeführt ist. Denaturierende Schichten können natürlich metallischen Charakter, wie Kupfer, aufweisen oder auch mit entsprechend getränkten Vliesmatten armiert sein. To solve this problem, an ionization filter for air purification is proposed, where the precipitation electrode is designed with denaturing properties is. Denaturing layers can of course have a metallic character, such as copper, have or be reinforced with appropriately soaked fleece mats.  

Ein weiterer erfindungsgemäßer Gedanke liegt darin, daß diese Niederschlagselektrode wechselweise denaturierend ausgebildet ist durch zum Beispiel wechselwirkende pH-Werte 1 und pH-Wert 14.Another idea of the invention is that this Precipitation electrode is alternately denaturing by Example of interacting pH 1 and pH 14.

Hierdurch ist auch die Gewähr gegeben, daß z. B. Sprühmittel mit in die Kanäle von Klimaanlagen eingegeben werden können, die pilzvernichtend wirken, denn diese werden schlußendlich am endständigen Ionisationsfilter niedergeschlagen mit niedrigstem Druckverlust.This also ensures that z. B. spray with in the channels of Air conditioning systems can be entered that have a fungicidal effect, because these are finally deposited on the terminal ionization filter with lowest pressure loss.
