Problems solved by technology

This can lead to a large waste of material and is disadvantageous for environmental and economical reasons
[0013] Another disadvantage of current cartridge filters is the small air flow area
Therefore, the flow resistance is high and results in a pressure loss of the air as it flows through
Furthermore, the production of the perforated plate circumference is expensive and entails considerable material losses

Embodiment Construction

[0035] exist figure 1 The cartridge filter 1 is illustrated in an exploded view. The cartridge filter 1 comprises an inner cylindrical wall 3, an intermediate intermediate space 5 through which the exhaust gas subsequently flows. The outer second cylindrical wall 4 together with the inner cylindrical wall 3 forms an inner space 6, as in figure 2 visible in . Two cylindrical walls 3, 4 and in image 3 The first annular end wall 7 shown in the figure is connected materially, for example by spot welding. Then, on the other end of the cartridge filter 1 , the first portion 9 of the second circular end wall 8 is connected to the inner cylindrical wall 3 . The first part 9 is collar-shaped, wherein the collar is inserted into the central intermediate space 5 . A radially outwardly extending edge flange 10 bears against the inner cylindrical wall 3 . The first part 9 is fastened to the inner cylindrical wall 3 in a materially bonded manner.

Abstract

Cartridge filter (1) for the filtration of gaseous constituents from an air flow with the aid of a filter medium in the form of a bulk-like material, comprising a) a filter housing having a longitudinal axis; b) an inner cylindrical wall of the filter housing; c) an outer cylindrical wall of the filter housing; d) an annular first end wall; e) a circular second end wall; and f) means (13) for sealingly connecting the first end wall to a cartridge carrier; wherein g) the inner cylindrical wall and / or the outer cylindrical wall consist of metal plates.

Description

technical field [0001] The invention relates to a cartridge filter for filtering gaseous components formed by an air volume flow by means of a filter medium in the form of granular material, comprising: [0002] a) a filter housing with a longitudinal axis which encloses an inner space which is annular in cross section and in which the filter medium is arranged in such a way that the intermediate space between the materials can be is flowed by the volume flow of air to be filtered, [0003] b) the inner cylindrical wall of the filter housing, which has perforations for the air volume flow through, retains the filter medium in the inner space and separates the inner space from the cylindrical central space , [0004] c) The outer cylindrical wall of the filter housing, which has perforations for the passage of the air volume flow while retaining the filter medium in the inner space and which separates the inner space from the environment of the cartridge filter separated, ...
