Abstract

A device for preparing, in particular filtering, room air contains a number of filter stages which are flowed through consecutively by the room air. For relieving the filter stages, a self-cleaning pre-filter is connected in front of these. This filter comprises a belt-shaped, flexible collector surface, on which the substances extracted from the room air can be obtained as a deposit. A reversal point of this collector surface which is designed as a continuous belt is made in the form of a round brush which, during the movement past of the continuous belt, performs a stripping action. The stripped particles are caught in a collecting container and then disposed of. The counter-electrode interacting with the belt-shaped collector surface is arranged in the room which is surrounded by the collector surface.

Description

Die Erfindung betrifft eine Vorrichtung zur Aufbereitung, insbesondere Filtrierung, der Raumluft nach dem Oberbegriff des Hauptanspruchs.The invention relates to a device for processing, especially filtration, the indoor air according to the generic term of the main claim.

Derartige Vorrichtungen werden dazu eingesetzt, die Raum­ luft von Schwebepartikeln, Dämpfen, Aerosolen usw. zu befreien. Entsprechend den Substanzen, die aus der Raum­ luft entfernt werden sollen, sind spezialisierte Filter­ stufen vorgesehen. Hierzu zählen insbesondere mechanische Filter, darunter solche, die mit Filterpapieren arbeiten, sowie physikalisch-chemische Filter, insbesondere Adsorp­ tionsfilter (Aktivkohlefilter). Werden diese Filterstufen in stark belasteter Raumluft eingesetzt, so gelangen sie rasch an ihre Aufnahmegrenze, so daß sie erneuert bzw. reaktiviert werden müssen. Der häufige Wechsel der Filter­ stufen steht in vielen Bereich bis heute dem wirksamen Einsatz von Luftaufbereitungsfiltern entgegen.Such devices are used to space air from suspended particles, vapors, aerosols etc. to free. According to the substances that come out of the room to remove air are specialized filters stages provided. These include, in particular, mechanical ones Filters, including those that use filter paper, as well as physico-chemical filters, especially adsorp tion filter (activated carbon filter). Will these filter stages used in heavily polluted indoor air, so they get quickly to their intake limit so that they renew or need to be reactivated. The frequent change of filters stages is still the most effective in many areas Against the use of air treatment filters.

Eine Vorrichtung der im Oberbegriff des Hauptanspruches angegebenen Art ist in der DE-OS 28 02 965 beschrieben. Hier stehen sowohl die Kollektorfläche als auch die zuge­ hörige Gegenelektrode räumlich still. Die Kollektorfläche ist gleichzeitig als Aktivkohlefilter gestaltet. Hat sich nach einer gewissen Betriebsdauer das Aktivkohlefilter zugesetzt, muß es ausgetauscht werden.A device in the preamble of the main claim specified type is described in DE-OS 28 02 965. Here are both the collector area and the supplied appropriate counter electrode spatially silent. The collector area is also designed as an activated carbon filter. Has the activated carbon filter after a certain period of operation added, it must be replaced.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der im Oberbegriff des Hauptanspruchs angegebenen Art derart auszugestalten, daß das elektrostatische Vorfilter selbstreinigend ist und hierdurch der Wechsel bzw. die Reaktivierung der aktiven Elemente in den verschiedenen Filterstufen in erheblich weiter auseinanderliegenden Zeiträumen erfolgen kann.The object of the present invention is a device of the type specified in the preamble of the main claim to design such that the electrostatic prefilter is self-cleaning and thus the change or Reactivation of the active elements in the different Filter stages in considerably further apart  Periods can be done.

Diese Aufgabe wird durch die im Kennzeichen des Hauptan­ spruchs beschriebene Erfindung gelöst.This task is performed by the in the flag of the main solved described invention.

Der erfindungsgemäße Vorfilter wirkt als Entlastungsfilter für die nachfolgenden Filterstufen und zwar - im Gegensatz zu einem mechanischen Grobfilter, welches nur für Teilchen mit großen Abmessungen wirksam ist - auch für feinste Schwebeteilchen, Aerosole und Dämpfe. Unter der Wirkung des elektrischen Feldes, welches im Vorfilter wirkt, sowie ggf. durch den ionisierenden Einfluß zusätzlicher Elektro­ den werden die in der Luft befindlichen Substanzen auf der Kollektorfläche niedergeschlagen. Durch periodische Reinigung durch die als Abstreifeinrichtung ausgestaltete Umlenkeinrichtung wird die Kollektorfläche auch über lange Zeit hinweg saubergehalten. Die abgestreiften Partikel werden in einem Sammelbehälter aufgefangen und von dort aus entsorgt. Einzelheiten der Entsorgung sind nicht Gegen­ stand der vorliegenden Erfindung.The pre-filter according to the invention acts as a relief filter for the subsequent filter stages - in contrast to a mechanical coarse filter, which is only for particles is effective with large dimensions - even for the finest Hovering particles, aerosols and vapors. Under the effect the electric field that acts in the prefilter, and possibly by the ionizing influence of additional electro The substances in the air are exposed of the collector surface. Through periodic Cleaning by the designed as a scraper The collector surface is also deflected over a long period Keeped clean for a while. The stripped particles are collected in a collecting container and from there disposed of. Disposal details are not opposed stood of the present invention.

Durch den vorgeschalteten Vorfilter werden die nachfolgen­ den Filterstufen in einem so erheblichen Maß entlastet, daß ein Wechsel der aktiven Filterelemente nur in außer­ ordentlich großen Zeitabständen erforderlich ist. Dies macht es möglich, die erfindungsgemäße Vorrichtung auch in sehr belasteten Räumen, z.B. in Automobilen und derglei­ chen, zum Einsatz zu bringen. Die Spannung, die zwischen der Kollektorfläche und der Gegenelektrode wirkt, sollte im Bereich zwischen 8 und 20 kV liegen.They will follow through the upstream pre-filter relieved the filter stages to such a considerable extent, that a change of active filter elements only in except neatly large intervals is required. This makes it possible to use the device according to the invention in very busy rooms, e.g. in automobiles and the like chen to be used. The tension between the collector surface and the counter electrode should work are in the range between 8 and 20 kV.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the invention are in the Subclaims specified.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert; die einzige Figur zeigt schematisch das den nicht dargestellten weiteren Filterstufen vorgeschaltete elektrostatische Vorfilter einer Vorrichtung zur Aufbereitung von Raumluft.An embodiment of the invention is as follows explained in more detail with reference to the drawing; the only figure shows schematically that the other not shown  Electrostatic pre-filter upstream of filter stages a device for processing indoor air.

In einem in der Zeichnung nicht näher dargestellten äußeren Gehäuse, welches auch weitere, nachgeschaltete Filterstufen sowie ein Gebläse enthält, ist eine Kollektorfläche 419 angeordnet. Dieses ist als Endlosband ausgestaltet und wird von einer Vielzahl von Öffnungen 435 durchsetzt. Das Endlosband 419 umläuft eine Antriebswalze 427, die von einem nicht dargestellten Antriebsmotor in Drehung versetzt wird. Die zweite Umkehreinrichtung für die Kollek­ torfläche 419 wird von einer Rundbürste 423 gebildet, die als Abstreifeinrichtung dient. In dem von der Kollektor­ fläche 419 umschlossenen Raum befindet sich eine Gegenelek­ trode 421, die sich aus einer Vielzahl spitzer, Ionen erzeugender Elektrodennadeln 425 zusammensetzt.A collector surface 419 is arranged in an outer housing, not shown in the drawing, which also contains further downstream filter stages and a blower. This is designed as an endless belt and is penetrated by a large number of openings 435 . The endless belt 419 runs around a drive roller 427 , which is set in rotation by a drive motor, not shown. The second reversing device for the collector gate surface 419 is formed by a round brush 423 , which serves as a stripping device. In the space enclosed by the collector surface 419 there is a counterelectrode 421 , which is composed of a plurality of pointed, ion-generating electrode needles 425 .

Die von der Rundbürste 423 von der Innenseite der Kollek­ trofläche 419 abgestreiften Partikel werden durch die Öffnungen 435 hindurch in einen Sammelbehälter 431 gebür­ stet. Zusätzlich kann die Rundbürste 423 als Wendelbürste ausgestaltet sein. Auf diese Weise übt sie zusätzlich eine Förderwirkung derart aus, daß die abgeriebenen Parti­ kel axial, bezogen auf die Achse der Rundbürste 423 bis an das seitliche Ende der Kollektorfläche 419 gefördert werden, von wo sie dann in den Sammelbehälter 431 fallen.The particles stripped by the round brush 423 from the inside of the collector surface 419 are brushed through the openings 435 into a collecting container 431 . In addition, the round brush 423 can be designed as a spiral brush. In this way, it also exerts a conveying effect in such a way that the abraded parti axially, based on the axis of the round brush 423 , are conveyed to the side end of the collector surface 419 , from where they then fall into the collecting container 431 .

Die Anströmung der Kollektorfläche 419 kann sowohl tangen­ tial, also in der Zeichnung senkrecht zur Zeichenebene, als auch senkrecht durch die Öffnungen 435 hindurch erfol­ gen.The flow onto the collector surface 419 can be both tangential, that is to say perpendicular to the plane of the drawing in the drawing, and also perpendicular to the openings 435 .

Selbstverständlich ist es möglich, zur Kapazitätserhöhung mehrere der beschriebenen Einheiten "parallel" zueinander anzuordnen.Of course it is possible to increase capacity several of the units described "parallel" to each other to arrange.

Zwischen der Kollektorfläche 419 und der Gegenelektrode 421 wirkt eine Spannung, deren Größe zwischen 8 und 20 KV liegt.A voltage acts between the collector surface 419 and the counter electrode 421 , the size of which lies between 8 and 20 KV.
