Description

Atemschutzfilter gegen Kohlenoxyd Die Erfindung betrifft ein Atemschutzfilter gegen Kohlenoxyd, das eine Einrichtung zum Kühlen der Atemluft aufweist. Bei einem bekannten Atemschutzfilter dieser Art ist in der Strömungsrichtung vor dem Katalysator in einem besonderen Behälter ein Kühlmittel angeordnet, das von der im Katalysator erhitzten Luft zwecks Kühlung umströmt wird.Respiratory protection filter against carbon oxide The invention relates to a respiratory protection filter against carbon oxide, which has a device for cooling the breathable air. At a known respiratory protection filter of this type is in the flow direction upstream of the catalytic converter A coolant is placed in a special container, which is different from that in the catalytic converter heated air is circulated for cooling.

Die Erfindung besteht nun darin, daß. die Katalysatormasse und die Kohlendioxydabsorptionsmasse zwischen zwei je mit einer axialen Öffnung versehenen Platten angeordnet und durch eine mit Randöffnungen versehene Platte getrennt sind und däß zwecks Kühlung der in der Katalysatormasse envärm.-ten Luft entlang der zwischen den beiden mit axialen Öffnungen versehenen Platten liegenden Gehäusewand ein ringförmiger Luftverteilungsraum angeordnet ist.The invention consists in that. the catalyst mass and the Carbon dioxide absorption mass between two each provided with an axial opening Plates are arranged and separated by a plate provided with edge openings and for the purpose of cooling the air heated in the catalyst mass along the housing wall lying between the two plates provided with axial openings an annular air distribution space is arranged.

Durch diese Ausbildung eines Atemschutzfilters soll eine möglichst große Berührungsüäch e der Atemluft mit der Außenluft und somit eine gute Kühlwirkung erreicht werden. Die Kühlwirkung kann noch dadurch vergrößert werden, daß der den ringförmigen Luftverteilungsraum begrenzende Teil der Gehäusewand mit Wellen, Rippen oder Lamellen versehen ist.This training of a respiratory protection filter should as possible large area of contact between breathing air and outside air and thus a good cooling effect can be achieved. The cooling effect can be increased by the fact that the Ring-shaped air distribution space delimiting part of the housing wall with waves, ribs or lamellas.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Längsschnitt dargestellt. Die Luft strömt zunächst durch den Vortrockner a, dann durch die axiale Öffnung der Platte h, den Nachtrockner b und den Katalysator c in den ringförmigen Luftverteilungsraumm. Von diesem aus gelangt sie durch die Kohlendioxydabsorptionsmassed, die Kohleschicht e und dieaxiale Öffnung der Platte k in die Trockenschiebt/ und die Warmschichtg. Auf dem beschriebenen Weg strömt die Atemluft, die sich beim Durchströmen der Katalysatormasse c erwärmt, an den Außenwänden des Filtergehäuses vorbei und kühlt sich hierbei ab. Die Kühlung kann dadurch verstärkt werden, daß das Filtergehäuse in dem zwischen den mit axialen Öffnungen versehenen Platten h, h gelegenen Teil auf der Außenseite Wellen, Rippen oder Lamellen L aufweist, .durch die die Kühlfläche noch vergrößert wird. Die Katalysatormasse und die Kohlendioxydabsorptionsmasse sind durch eine mit Randöffnungen versehene Plattei getrennt.In the drawing, an embodiment of the subject invention is shown in longitudinal section. The air flows first through the pre-dryer a, then through the axial opening of the plate h, the post-dryer b and the catalyst c into the annular air distribution space. From this it passes through the carbon dioxide absorption mass, the carbon layer e and the axial opening of the plate k into the drying room / and the warm layer g. On the path described, the breathing air, which is heated when flowing through the catalyst mass c, flows past the outer walls of the filter housing and cools down in the process. The cooling can be increased in that the filter housing in the part located between the plates h, h provided with axial openings has corrugations, ribs or lamellas L on the outside, through which the cooling surface is increased. The catalyst mass and the carbon dioxide absorption mass are separated by a plate provided with edge openings.
