Abstract

Dry filter for cleaning exhaust gases comprises a filling member (4) in a filter basket (3) and a ventilator (1) unit for room air, fresh air or exhaust gas streams. The dirt, smells and germs in the gas oxidise and die on the lime and salt layers, so the salt layer improves the air in a way similar to ionisation.

Description

Handelsübliche Füllkörper, aus Kunststoff oder Keramik werden im Kalkschlamm getaucht, bei entsprechender Viscosität.Commercial packing, made of plastic or ceramic immersed in lime sludge, with appropriate viscosity.

Der feuchte Calciumhydroxid-Schlamm, der auf der Ober- u. Innenfläche der Füllkörper haftet, wird dann mit Bäckersalz oder je nach Einsatz mit Jodsalzen bestreut.The moist calcium hydroxide sludge, which on the upper u. Inner surface of the packing adheres, then with baker's salt or sprinkled with iodine salts depending on the application.

Bäckersalz, wie es auf den Brezeln aufgebracht wird ist sehr grobkörnig.Bakery salt as it is applied to the pretzels is very coarse-grained.

Setzt man als Trockenmasse Calciumhydroxid zu, so wird durch Zugabe von Wasser und Bindemittel (Papierfaser) ein zäher Ca-Teig der dann nach der Reaktion als Carbonatfilter zu be­ zeichnen wäre.If calcium hydroxide is added as a dry matter, then is Adding water and binder (paper fiber) a tough Ca dough which is then used as a carbonate filter after the reaction would draw.

Nimmt man als Grundstoff Calciumoxid (CaO) mischt mit Wasser und Bindemittel (Wasserglas) so haben wir nach der Reaktion und Trocknung, ein Calciumhydroxid Trocken-Füll-Körper.If you take calcium oxide (CaO) mixed with water as the raw material and binder (water glass) so we have after the reaction and drying, a calcium hydroxide dry-fill body.

Der Unterschied besteht darin, daß der Carbonat-Trockenfilter nur noch leicht alkalisch ist, im Gegensatz zum Calciumhydroxid Trockenfilter der einen hohen pH-Wert von über 8-10 pH an­ zeigen kann.The difference is that the carbonate dry filter is only slightly alkaline, in contrast to calcium hydroxide Dry filter which has a high pH of over 8-10 pH can show.

Dieser pH Wert von 8-10 pH kann auch zur Geruchsver­ nichtung bei Abluft- und Abgasströmen eingesetzt werden.This pH value of 8-10 pH can also be used for odor control exhaust air and exhaust gas flows.

Dieses Beschichtungsverfahren auf handelsüblichen Füllkörpern kann sehr vielseitig in Luftströmen eingesetzt werden. This coating process on commercially available packing can be used very versatile in air flows.  

Diese beschichteten Füllkörper können auch für Abgaszwecke mit Eisenoxid, mit Glasstaub, mit Aluminiumstaub beschichtet werden, die Grundbeschichtung ist immer Kalk, der die auf­ gestreuten Oxidationsmittel bindet.This coated packing can also be used for exhaust gas purposes with iron oxide, with glass dust, coated with aluminum dust the base coat is always lime, which is the one on scattered oxidant binds.

Wie in Fig. 1 dargestellt wird beim Salinen Aktiv Klima Ver­ fahren ein Ventilator (1) benutzt um die angesaugte Luft über den Filterkörper (3) zu drücken und damit werden die im Korb eingesetzten Füllkörper (4) gleichmäßig von der angesaugten Luft bestrichen.As shown in Fig. 1 is used in saline active air conditioning Ver a fan ( 1 ) is used to press the sucked air over the filter body ( 3 ) and thus the filler ( 4 ) used in the basket are evenly coated by the sucked air.

So wie im Kurgarten die Salinensalze über Aufbauwände laufen, um zu verdunsten und damit das Luftklima beeinflussen, so nimmt der Luftstrom beim Salinen Aktiv Klima Verfahren auf Grund einer gewissen Luftfeuchtigkeit, Salzmigroteilchen auf und trägt diese in der Raumluft weiter.Just as in the spa garden, the salt salts run over the walls, to evaporate and thus influence the air climate, so the air flow takes up in the Salinen Aktiv Klima process Due to a certain humidity, salt migra particles and carries it on in the air.

Die Calciumcarbonatbeschichtung auf den Füllkörpern nimmt Schmutzpartikel, Geruchsstoffe, Bakterien usw. auf und hält damit die Zuluft oder Kreislaufluft bakterienfrei.The calcium carbonate coating on the packing takes off Dirt particles, odorous substances, bacteria etc. on and lasts so that the supply air or circulating air is bacteria-free.

Dieses Carbonattrockenverfahren könnte auch Lüftungs- und Klima­ anlagen die als Bakterienschleudern zu bezeichnen sind, im Nacheinbau eines Ca-Filters hygienisch sauber gehalten werden.This carbonate drying process could also ventilation and air conditioning plants that can be described as bacterial spinners, kept hygienically clean after installing a Ca filter will.

Im Unterschied so z. B. bei Kohleaktivfiltern die je mehr Schmutz diese aufnehmen müssen sich sehr schnell zusetzen und damit ihre Wirkung verlieren, bleibt der Ca-Filter immer offen, weil die Schmutz- u. Geruchspartikel auf der Kalkoberfläche oxidieren. Das oxidierte Schmutzteil löst sich von der Kalkoberfläche und fällt zu Boden, die dahinterliegende Kalkschicht ist damit frei.In the difference so. B. with carbon active filters the more dirt they have to pick up very quickly and thus lose their effect, the Ca filter always remains open because the dirt and Oxidize odor particles on the lime surface. The oxidized dirt part detaches from the lime surface and falls to the ground, the limestone layer behind it is free.
