Abstract

A sorption filter device includes a sorption filter element including at least two sorption bodies with at least one sorbent, the at least two sorption bodies being arranged in a V-shape and enclosing an intermediate space that is open at a head side thereof, an outer sealing element running around an outer circumference of the head side, and an inner sealing surface arranged at the head side and running around a circumference delimiting the intermediate space at the head side. The sorption filter device further includes a housing including a first housing part configured to receive the sorption filter element, and a second housing part detachably connectable to the first housing part and configured to close the housing in a closed state thereof, the sorption filter element being received in the first housing part in such a way that the head side faces the second housing part.

Claims (24)

1 . A sorption filter device comprising:

a sorption filter element comprising:

at least two sorption bodies with at least one sorbent, the at least two sorption bodies being arranged in a V-shape and enclosing an intermediate space that is open at a head side thereof;

an outer sealing element running around an outer circumference of the head side; and

an inner sealing surface arranged at the head side and running around a circumference delimiting the intermediate space at the head side;

a housing comprising:

a first housing part configured to receive the sorption filter element;

a second housing part detachably connectable to the first housing part and configured to close the housing in a closed state thereof, the sorption filter element being received in the first housing part in such a way that the head side of the sorption filter element faces the second housing part;

at least one first air inlet/outlet; and

at least one second air inlet/outlet, the sorption filter element being arranged between the at least one first air inlet/outlet and the at least one second air inlet/outlet in a fluidic way, and at least one of the at least one first air inlet/outlet and the at least one second air inlet/outlet being arranged at the second housing part; and

an air guidance element arranged between the sorption filter element and the second housing part, and configured to protrude into the intermediate space at the head side in a mounted state of the second housing part.

2 . The sorption filter device according to claim 1 , wherein the inner sealing surface of the sorption filter element is arranged within an inner space of the sorption filter element.

3 . The sorption filter device according to claim 1 , wherein the air guidance element comprises an outer contour corresponding to a contour of the intermediate space.

4 . The sorption filter device according to claim 1 , wherein the air guidance element comprises air guidance side walls having a that are grid-like arrangement of struts and openings, the openings separated from each other by the struts.

5 . The sorption filter device according to claim 1 , wherein the air guidance element is connected to the sorption filter element.

6 . The sorption filter device according to claim 1 , further comprising an air heating and guidance mechanism comprising:

the air guidance element; and

an axial sealing element configured to lie against the inner sealing surface of the sorption filter element in the mounted state of the second housing part.

7 . The sorption filter device according to claim 6 , wherein the housing further comprises a circumferential outer sealing surface against which the outer sealing element of the sorption filter element lies in the mounted state of the second housing part.

8 . The sorption filter device according to claim 7 , wherein the circumferential outer sealing surface of the housing is axially set back relative to the axial sealing element of the air heating and guidance mechanism.

9 . The sorption filter device according to claim 6 , wherein the air heating and guidance mechanism further comprises a heating element arranged within the second housing part and arranged axially beyond the intermediate space.

10 . The sorption filter device according to claim 1 , wherein the housing further comprises a circumferential outer sealing surface against which the outer sealing element of the sorption filter element lies in the mounted state of the second housing part.

11 . The sorption filter device according to claim 10 , wherein the circumferential outer sealing surface of the housing is arranged at the first housing part or at the second housing part.

12 . The sorption filter device according to claim 1 , wherein the inner sealing surface is axially set back relative to the outer sealing element.
