Abstract
Description
Die Erfindung betrifft ein Chemisorptionsfilter, insbe sondere für Klimaanlagen, nach dem Oberbegriff des Patent anspruchs 1.The invention relates to a chemisorption filter, in particular especially for air conditioning, according to the generic term of the patent claim 1.
Ein derartiges Chemisorptionsfilter ist durch die DE 87 00 521 U1 bekannt.Such a chemisorption filter is due to the DE 87 00 521 U1 known.
Beim Einbau von Filtern in Klimakanäle gibt es immer wieder Schwierigkeiten, durch Rahmen und dergleichen eine ab dichtende Filterfläche einzutragen.When installing filters in air conditioning ducts, there are always Difficulties starting with frames and the like enter sealing filter surface.
Es ist durch viele Anmeldungen der Firmengruppe Hölter bekannt, daß sauer-alkalische wechselwirkende Filter eingesetzt werden sollen, um eine bakterizide Wirkung zu erzielen, wobei gleich zeitig natürlich auch die Kohlenwasserstoffe über die sauren Bestandteile wie HCL, HF, NOx, SO₂ abgeschieden werden sollen.It is known from many registrations by the Hölter Group, that acid-alkaline interacting filters are used to achieve a bactericidal effect, being the same of course also the hydrocarbons via the acidic components such as HCL, HF, NOx, SO₂ are deposited should.
Der Erfindung liegt die Aufgabe zugrunde, den teuren Aufwand der abdichtenden Filterrahmen nicht notwendig zu machen. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Die Erfindung ermöglicht in vorteilhafter Weise, das Filter gleichzeitig als stabiles Traggerüst zu nutzen.The invention has for its object the expensive effort the sealing filter frame is not necessary. This task is characterized by the characteristics of the Claim 1 solved. The invention enables in advantageously, the filter at the same time as a stable Use scaffolding.
Eine vorteilhafte Ausgestaltung ist im Unteranspruch an gegeben.An advantageous embodiment is in the subclaim given.
Im folgenden wird das in der Zeichnung dargestellte Aus führungsbeispiel der Erfindung erläutert. In the following the Aus shown in the drawing management example of the invention explained.
In der Zeichnung ist dargestellt:
mit 1 die Anströmseite, bestehend aus staub
bindenden Vliesfiltern und dergleichen,
mit 2 der selbst stabil in sich stehende Filter
körper in getränkter Ausführung, vorzugsweise
bestehend aus wabenförmigen Keramikstrukturen, die
entsprechend der Aufgabenstellung stark alkalisch
getränkt sind, z. B. mit einer Soda-Tränkung.The drawing shows:
with 1 the upstream side, consisting of dust-binding fleece filters and the like, with 2 of the self-standing self-standing filter body in an impregnated version, preferably consisting of honeycomb-shaped ceramic structures that are strongly alkaline soaked according to the task, z. B. with a soda soak.
Mit 3 wird angedeutet, daß auf der Abströmseite dann zur Aufnahme von Kohlenwasserstoffen nochmals eine A-Kohleschicht aufgeklebt wird, die in Form von Einzelkörnern auf Matten oder auch als Schaum körper aufgeklebt sein kann.With 3 it is indicated that an A-carbon layer is then glued on the outflow side to absorb hydrocarbons, which can be glued in the form of individual grains on mats or as a foam body.
Mit 4 ist ein Dicht-Rahmen bezeichnet, der sowohl den Tragkörper aus keramisch-getränktem Material 2 umschließt als auch die Anströmseite vliesförmiger Körper 1 und auf der Abströmseite die A-Kohle 3. 4 with a sealing frame is referred to, which encloses both the support body made of ceramic-impregnated material 2 and the inflow side non-woven body 1 and the A-charcoal 3 on the outflow side.
Der Dicht-Rahmen bzw. auch Dichtleiste 4 wird in einfachster Art und Weise, so wie zeichnerisch dargestellt, zur Umklammerung der Flächenkörper 1, 2 und 3 genutzt und ist gleichzeitig die Abdichtung innerhalb eines Gehäuses. The sealing frame or sealing strip 4 is used in the simplest way, as shown in the drawing, for gripping the flat bodies 1 , 2 and 3 and is at the same time the seal within a housing.
Durch diese verfahrenstechnische Zusammensetzung von Filterkörpern ist der handwerkliche Betrieb in der Lage, auch auf den Baustellen durch das Zu schneiden und Anpassen an die gegebenen Kanäle solche Chemisorptionsfilter anzupassen.Due to this procedural composition of filter bodies is the manual operation in able to access the construction sites cut and adapt to the given channels to adapt such chemisorption filters.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungs formen und Beschreibungen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, daß nicht wie bisher ein rahmenförmiger Körper genommen werden muß, um in Klimakanälen eingebaut zu werden, sondern als selbsttragende Schicht eine poröse Masse genommen wird, die vorzugsweise alkalisch getränkt ist und auf der Anströmseite mit einem staubabscheidenden Vliesfilter, vorzugsweise sauer getränkt, ausgebildet ist, und auf der Abströmseite mit 3 eine A-Kohlebeschichtung aufweist, vorzugs weise in geschäumter Ausführung, wobei die An strömseite 1 und die A-Kohle-Abströmseite 3 mit dem stabilisierenden, porösen Körper 2 vorzugsweise aus getränkter Keramik hergestellt in Punktklebetechnik verbunden ist und mit der Umhüllung 4 klammer technisch umschlossen ist bei gleichzeitiger Ab dichtwirkung der Umhüllung 4.Of course, the invention is not limited to the forms and descriptions described in detail above, but numerous modifications are possible without, however, deviating from the basic idea that a frame-shaped body does not have to be used as before to be installed in air-conditioning ducts, but instead a porous mass is used as a self-supporting layer removed, the impregnated preferably alkaline, and is preferably impregnated acid on the upstream side with a dust-collecting fleece filter is formed, and has on the outflow side 3 an activated carbon coating, preferably, in the foamed embodiments, the On the flow side 1 and the A-carbon outflow side 3 is connected to the stabilizing, porous body 2, preferably made of impregnated ceramic, using point adhesive technology and is technically enclosed with the sheathing 4 with a simultaneous sealing effect from the sheathing 4 .
