Gas or air filter

The present innovation preferably relates to a gas or air filter in a cylindrical shape, especially with an activated carbon filling.

In the case of gas or air filters, the filters penetrate from the Harmful gas components carried along by gas or air flow, preferably separated out by adsorption in an activated carbon layer. This layer can also be impregnated with special active ingredients to improve its excretion. Important for a complete as possible The elimination of harmful gases is both an effective filter layer that is as fresh as possible and one that is sufficiently longitudinal Residence time of the carrier gas flow in this layer.

In air conditioning and ventilation systems, work has hitherto been carried out on the preparation of atmospheric outside air with large flow cross-sections, relatively high gas penetration speeds and frequent changes of activated carbon. Here, particle-bound Geruehsstoffe and toxic components from the air to be filtered were eliminated by the finest p _a rtikelfilter. The gas adsorption filters used in these systems were and continue to be in spite of this

their low strength and the short dwell time of the air sufficient for the elimination of the harmful gas components. Cell sealing surfaces also did not appear disruptive. the Cells were not refilled and because of their light construction they were not used again. Pure these air conditioning and ventilation systems - is currently used more and more interchangeable, plastic cartridges that can be inserted into the cell housing, which seal relatively well. This largely solves the problem of renewing the adsorption mass.

So far, however, it has been missing from the more and more prominent ones Adsorption filters in nuclear reactor operation the possibility with this existing type of cell, which is essential to allow increasing dwell time. Here are layers of activated carbon with 10 times the layer thickness and more is required. The present innovation allows variations in the application that were previously available with one and the same device were not available.

Place a further middle piece of a pIter chamber with bulk material between two pre-positioned sieve parts and a further connection element 3 or 4 in the free connection flange 10. This then gives two separate gas filters "in which the air flow according to FIG. 2", for example, enters from the left and exits to the right.

{ occurs. In this way, as shown in FIG. 2, three or "any number of such gas filters" can be put together, "in which, for example, the air enters on the left-hand side and exits on the right-hand side. A closely built filter group consisting of "one piece" is obtained on this yfeise
