Problems solved by technology

[0008] A disadvantage of the filters known from the prior art is that charges build up and undesired spark discharges can occur
This represents a safety risk especially in explosive atmospheres such as those used in the oil and gas industry

Embodiment Construction

[0044] Figure 1a A first embodiment variant of the filter element 10 according to the invention is shown. The filter element 10 has a frame 2 in which a plurality of filter bodies 1 are arranged. Filter body 1 can respectively have a kind of configuration, as it is in Image 6 As outlined in : The filter body 1 is designed here as a honeycomb body 1.1 with a plurality of openings 1.2 arranged side by side. The corresponding opening 1.2 is the end of a channel 1.3 which is open on both sides. The channels 1.3 are separated from each other by partition walls. as in Image 6 A corresponding opening 1.2 can have a square base area, as in the example of FIG. Optionally, for example rectangular or hexagonal openings are also conceivable, which are reminiscent of honeycombs.

[0045] The filter bodies 1 are connected to one another by means of an adhesive 5 so that they are held firmly in the frame 2 . However, the adhesive 5 is not electrically conductive here. An electr...

Abstract

The invention relates to a filter element for adsorbing harmful gases from a fluid flow, which includes: a frame (2) and a plurality of filter bodies (1) arranged at a distance next to one another inthe frame. A respective filter body (1) has a plurality of openings (1.2). A respective filter body (1) is connected to at least one other of the filter bodies (1) via a respective contact element (3)configured for electrical dissipation. The invention also relates to a filter for use in an explosive environment, comprising at least one such filter element (10).

Description

technical field [0001] The invention relates to a filter element according to the preamble of claim 1 and a filter according to claim 9 with such a filter element. Background technique [0002] A filter element is known from WO 2010 / 049 052 A1, which is designed as a so-called combined filter. Such filter elements filter particles and adsorb gases. Filter elements of this type can be used to keep the passenger compartment as free of harmful substances as possible. [0003] Against this background, a shaped activated carbon body is known from DE 101 04 882 B4, which has a honeycomb structure. Activated carbon shaped bodies are produced by extruding activated carbon and other substance mixtures and are used as adsorptive filters. [0004] The purpose of this type of activated carbon filter is to: Filter harmful gases out of the air stream. [0005] A further filter element is known from DE 101 50 062 B4, which has a shaped activated carbon body with a honeycomb structure. ...
