Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Abschei­ dung von Stäuben, Pilzen, Viren, Keimen, Bazillen und gas­ förmigen und/oder aerosolförmigen Schadstoffen aus Luft, die in nachstehender Reihenfolge einen Grobabscheidefilter, eine Ozonisierungsstrecke, einen Ventilator, eine Ionisierungs­ strecke und einen Mehrschichten-Chemiesorptionsfilter, der aus übereinander gelagerten, durch staubfilternde Schichten voneinander getrennten Schüttbettungen besteht, aufweist, wobei der eingesetzte Mehrschichten-Chemiesorptionsfilter in Strömungsrichtung gesehen nacheinander folgende Schichten aufweist:The invention relates to a device for separation dusts, fungi, viruses, germs, bacilli and gas shaped and / or aerosol pollutants from air, the a coarse separation filter, one in the following order Ozonization line, a fan, an ionization stretch and a multi-layer chemical sorption filter, the from superimposed, through dust filtering layers there are separate beddings, the multilayer chemical sorption filter used in In the direction of flow, successive layers are seen having:

  • a) zunächst eine alkalische Schicht, dann eine saure Schicht oder umgekehrt, wobei die saure Schicht aus einem Blähstoff mit großer kapillarer Struktur, der mit Eisen-III-, Eisen-II-Salzen bzw. Ammoniumeisen­ sulfat getränkt ist, besteht;a) first an alkaline layer, then an acid one Layer or vice versa, the acidic layer being made of an expanded material with a large capillary structure, the with iron III, iron II salts or ammonium iron is soaked in sulfate;
  • b) eine neutralisierende Schicht undb) a neutralizing layer and
  • c) eine feinstaubabweisende Schicht.c) a fine dust repellent layer.

Eine derartige Vorrichtung ist in der DE 36 20 666 A1 be­ schrieben, bei der es sich um die Offenlegungsschrift des Hauptpatents handelt.Such a device is in DE 36 20 666 A1 , which is the disclosure of the  Main patent acts.

Der Erfindung liegt die Aufgabe zugrunde, die in der DE 36 20 666 A1 beschriebene Vorrichtung derart weiterzubil­ den, daß ihre Abscheideleistung verbessert ist.The invention is based, which in the DE 36 20 666 A1 described device to continue such that their separation performance is improved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwi­ schen den einzelnen Chemiesorptionsmassen elektrisch auflad­ bare Gewebefilterschichten als Trennschichten angeordnet und diese zum Aufbau eines elektrischen Feldes an einen Hoch­ spannungsgenerator angeschlossen sind. Durch den Aufbau des elektrischen Feldes kann im Zusammenwirken mit der Ioni­ sierungsstrecke eine verbesserte Agglomeration zwischen den Chemiesorptionsfilterschichten bei gleichzeitiger Vorschaltung der hochspannungsbetriebenen Ozonisierungsstrecke bewirkt werden.This object is achieved in that between electrically charge the individual chemical sorption masses bare fabric filter layers arranged as separating layers and this to build an electrical field on a high voltage generator are connected. By building the electric field can interact with the ioni an improved agglomeration between the Chemical sorption filter layers with simultaneous pre-connection the high-voltage ozonization line will.

Eine weitere Verbesserung der Abscheideeigenschaften der Vorrichtung wird erzielt, wenn auch das Gehäuse des Chemie­ sorptionsfilters elektrisch aufladbar ist.Another improvement in the separation properties of the Device is achieved, albeit the housing of the chemistry sorption filter is electrically chargeable.

Vorteilhaft können die Trennschichten und/oder das Gehäuse als Dielektrikum ausgeführt sein.The separating layers and / or the housing can be advantageous be designed as a dielectric.

Im folgenden wird die Erfindung an Hand einer Ausführungs­ form unter Bezugnahme auf die Zeichnung näher erläutert, in der schematisch die erfindungsgemäße Vorrichtung darge­ stellt ist. In the following the invention is based on an embodiment form explained in more detail with reference to the drawing, in which the device according to the invention is shown schematically represents is.  

Eine schadstoffbeladene Luftströmung 1 trifft auf eine elek­ trisch aufladbare Trennschicht 2, die als Gewebefilterschicht ausgebildet sein kann und die zur Vorrichtung zur Abschei­ dung gehört. Auf die Trennschicht 2 folgt eine Chemiesorp­ tionsmassenschicht 3, darauf eine Trennschicht 4, die als Dielektrikum ausgebildet ist und auf die eine weitere Che­ miesorptionsmassenschicht 3 folgt. Mit 5 ist ein Gehäuse be­ zeichnet, das wie die Trennschicht 4 als Dielektrikum aus­ gebildet sein kann.A pollutant-laden air flow 1 meets an electrically chargeable separating layer 2 , which can be designed as a fabric filter layer and which belongs to the device for separation. The separating layer 2 is followed by a chemisorption mass layer 3 , followed by a separating layer 4 which is designed as a dielectric and which is followed by a further chemiesorption mass layer 3 . 5 with a housing is characterized, which, like the separating layer 4, can be formed as a dielectric.

Ein Ionisator und/oder Ozonisator kann als Ladungspol den Chemiesorptionsfilterschichten, den elektrostatisch geladenen Trennschichten, den dielektrischen Trennschichten und dem Gehäuse beigefügt sein.An ionizer and / or ozonizer can serve as the charge pole Chemical sorption filter layers, the electrostatically charged Separating layers, the dielectric separating layers and the Housing attached.
