Description

Die Erfindung betrifft eine Vorrichtung zur Aufbereitung, insbe­ sondere Filterung, der Raumluft nach dem Oberbegriff des Patent­ anspruches.The invention relates to a device for processing, in particular special filtering, indoor air according to the generic term of the patent claim.

Derartige Vorrichtungen werden dazu eingesetzt, die Raumluft von Schwebepartikeln, Dämpfen, Aerosolen usw. zu befreien. Ent­ sprechend den Substanzen, die aus der Raumluft entfernt werden sollen, sind spezialisierte Filterstufen vorgesehen. Hierzu zählen insbesondere mechanische Filter, auch solche, die mit Filter­ papieren arbeiten, sowie physikalisch-chemische Filter, insbe­ sondere Adsorptionsfilter (Aktivkohlefilter). Werden diese Fil­ terstufen in stark belasteter Raumluft eingesetzt, gelangen sie rasch an ihre Aufnahmegrenze, so daß sie erneuert bzw. re­ aktiviert werden müssen. Der häufige Wechsel der Filterstufen steht in vielen Bereichen bis heute dem wirksamen Einsatz von Luft­ aufbereitungsfiltern entgegen.Such devices are used for indoor air to remove suspended particles, vapors, aerosols etc. Ent speaking of the substances that are removed from the room air specialized filter stages are provided. Which includes especially mechanical filters, including those with filters papers work, as well as physico-chemical filters, esp special adsorption filter (activated carbon filter). Will this fil levels used in heavily polluted indoor air they quickly reached their intake limit, so that they renewed or re must be activated. The frequent change of filter levels still stands for the effective use of air in many areas processing filters.

Eine Vorrichtung der im Oberbegriff des Hauptanspruches ange­ gebenen Art ist in Fig. 3 der DE-OS 28 02 965 dargestellt. Auch bei diesem bekannten Abscheider ist die Kollektorfläche zylinder­ förmig gestaltet. Die Gegenelektrode befindet sich koaxial zur zylindrischen Kollektorfläche etwa in deren Mitte und ist nach Art einer "Rundbürste" mit einer Vielzahl von spitzen Elektroden­ nadeln ausgestaltet. Die Gegenelektrode steht jedoch gegenüber der Kollektorfläche still; es ist an allen Stellen zwischen Gegenelektrode und Kollektorfläche ein Abstand vorhanden. Die "Bürstenform" der Gegenelektrode in der DE-OS 28 02 965 hat also ihren Namen nur aus einer optischen Ähnlichkeit mit einer Rund­ bürste erhalten; eine Bürstenfunktion wird dort aber nicht aus­ geübt.A device of the type specified in the preamble of the main claim is shown in Fig. 3 of DE-OS 28 02 965. In this known separator, the collector surface is cylindrical. The counter electrode is located coaxially to the cylindrical collector surface approximately in the middle and is designed in the manner of a "round brush" with a plurality of pointed electrode needles. The counter electrode, however, stands still in relation to the collector surface; there is a gap at all points between the counter electrode and the collector surface. The "brush shape" of the counter electrode in DE-OS 28 02 965 thus got its name only from an optical similarity to a round brush; a brush function is not exercised there.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der eingangs genannten Art so auszugestalten, daß sie bei einfach­ stem Aufbau eine Reinigung der Kollektorfläche gestattet.The object of the present invention is a device of type mentioned so that they are simple system allows cleaning of the collector surface.

Diese Aufgabe wird durch die im Kennzeichen des Patentanspruches beschriebene Erfindung gelöst.This object is achieved in the characterizing part of the claim described invention solved.

Mit der vorliegenden Erfindung wird erstmals erkannt, daß die Gegenelektrode gleichzeitig als Abstreifeinrichtung ausgestaltet werden kann, mit welcher der Vorabscheider selbstreinigende Eigen­ schaften enthält. Hierzu muß zwischen der Gegenelektrode und der zylindrischen Kollektorfläche eine relative Drehbewegung bewirkt werden. Die Gegenelektrode wird durch Einfügen einer wendelförmigen Bürste aus isolierenden Borsten zu einer echten Bürste in funktionalem Sinne. Die isolierenden Borsten der wen­ delförmigen Bürste streifen bei der relativen Drehbewegung an der angeströmten Seite der Kollektorfläche entlang und entfernen von dort kontinuierlich die sich bildenden Niederschläge. Durch die Wendelform der in die Gegenelektrode integrierten zusätz­ lichen Bürste entsteht gleichzeitig ein Fördereffekt, durch wel­ chen die abgestreiften Partikel axial aus dem Innenraum der zylindrischen Kollektorfläche hinaus und in den Sammelbehälter gefördert werden.With the present invention it is recognized for the first time that the Counter electrode designed at the same time as a stripping device with which the pre-separator is self-cleaning contains. For this purpose, between the counter electrode and relative cylindrical movement of the cylindrical collector surface be effected. The counter electrode is made by inserting a spiral brush made of insulating bristles into a real one Functional brush. The insulating bristles of the wen del-shaped brush rub against the relative rotation along the exposed side of the collector surface and remove from there the precipitation that forms continuously. By the spiral shape of the additional integrated in the counter electrode brush also creates a promotional effect, through which Chen the stripped particles axially from the interior of the cylindrical collector surface and into the collection container be promoted.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Die einzige Figur zeigt einen Axialschnitt durch eine Vorrichtung zur Aufbereitung der Raumluft.An embodiment of the invention is described below the drawing explained in more detail. The only figure shows one Axial section through a device for processing the room air.

Wie der Zeichnung zu entnehmen ist, ist in einem Gehäuse 1 ein Filtereinsatz 3 auswechselbar befestigt. Der Filtereinsatz 3 umfaßt koaxial ineinander angeordnet einen selbstreinigenden Vorabscheider 9, der später ausführlicher erläutert wird, ein Aktivkohlefilter 11 sowie ein Faltenfilter 13, welches als akti­ ves Element ein Filterpapier enthält. Die Raumluft wird über eine Ansaugöffnung 7 im Deckel 5 des Filtereinsatzes 3 ange­ saugt und gelangt nach dem Durchtritt des Filtereinsatzes 3 in ein Gebläse 15, aus dessen Auslaßöffnung 17 sie dann wieder in den Raum abgegeben wird.As can be seen from the drawing, a filter insert 3 is exchangeably fastened in a housing 1 . The filter insert 3 comprises coaxially arranged one another, a self-cleaning pre-separator 9 , which will be explained in more detail later, an activated carbon filter 11 and a pleated filter 13 , which contains a filter paper as an active element. The room air is sucked in through a suction opening 7 in the cover 5 of the filter insert 3 and, after passing through the filter insert 3, passes into a blower 15 , from the outlet opening 17 of which it is then discharged back into the room.

Der Vorabscheider 9 enthält eine zylindrische Kollektorfläche 19, die mit einer Vielzahl von Durchtrittsöffnungen (in der Zeichnung nicht erkennbar) versehen ist. Koaxial innerhalb der zylindrischen Kollektorfläche 19 befindet sich eine kombinierte Bürste 21, die über eine Welle 29 von einem Antriebsmotor 27 um die Symmetrieachse der Kollektorfläche 19 verdreht werden kann. Die kombinierte Bürste 21 ist gleichzeitig Abstreifein­ richtung für den Innenmantel der Kollektorfläche 19 und Gegen­ elektrode, so daß zwischen der kombinierten Bürste 21 und der Kollektorfläche 19 ein hohes elektrisches Feld ausgebildet wird. Die Abstreifeinrichtung besteht aus einer wendelförmigen Bürste 23 aus isolierenden Borsten, welche bei der Drehbewegung der kombinierten Bürste 21 an der Innenfläche der Kollektorfläche 19 vorbeistreift und dort befindlichen Niederschlag löst. Die abgestreiften Partikel fallen unter dem Einfluß der Schwerkraft, unterstützt durch eine fördernde Wirkung der Wendelform der Bürste 23, in einen Sammelbehälter 31, aus dem sie in großen Zeitabständen in einer Weise entfernt werden, die nicht Gegen­ stand der vorliegenden Erfindung ist.The pre-separator 9 contains a cylindrical collector surface 19 which is provided with a large number of through openings (not recognizable in the drawing). Coaxial within the cylindrical collector surface 19 is a combined brush 21 which can be rotated by a drive motor 27 about the axis of symmetry of the collector surface 19 via a shaft 29 . The combined brush 21 is at the same time Abstreifein direction for the inner surface of the collector surface 19 and counter electrode, so that a high electric field is formed between the combined brush 21 and the collector surface 19 . The scraper device consists of a helical brush 23 made of insulating bristles, which brushes past the inner surface of the collector surface 19 during the rotary movement of the combined brush 21 and loosens the precipitate located there. The stripped particles fall under the influence of gravity, supported by a promoting effect of the helical shape of the brush 23 , in a collecting container 31 , from which they are removed at large intervals in a manner which is not the subject of the present invention.

Der "Kern" der kombinierten Bürste 21 besteht aus einer Viel­ zahl radial gerichteter, spitzer Elektrodennadeln 25, die im Bereich ihrer Spitzen hohe lokale elektrische Felder erzeugen und so die vorbeistreifende Raumluft bzw. die hierin enthal­ tenen, zu entfernenden Substanzen ionisieren.The "core" of the combined brush 21 consists of a large number of radially directed, pointed electrode needles 25 , which generate high local electric fields in the area of their tips and thus ionize the air passing by or the substances contained therein to be removed.
