Embodiment Construction

[0031] Figures 1 to 4 A schematic view of a filter element 1 according to the invention designed according to the invention for filtering exhaust gases or process gases is shown. as from figure 1 It can be seen that the filter element 1 is formed in the form of a filter cartridge and has a substantially hollow cylindrical filter body 2 closed hemispherically at one end, namely the lower end 3, and at its opposite end, That is, the upper end 4 is open and defines the inner space 5 of the filter element 1 . At the open end 4 of the filter body 2 a radially protruding conical collar 6 is formed which tapers in the direction of the closed end 3 of the filter body 2 .

[0032] The filter body 2 defines a longitudinal direction R and is divided along this longitudinal direction R into two substantially cylindrical tubular filter body elements 7, 8 at their ends 9, 8 facing each other. 10 places are connected to each other. To this end, the filter body elements 7 , 8 have at the...

Abstract

The invention relates to a filter element (1), in particular a filter candle, for filtering exhaust gases or process gases, comprising a filter body (2), which defines a longitudinal direction (R) andis divided along said longitudinal direction into a plurality of substantially tubular filter body elements (7, 8), which are connected in pairs at the end sections (9, 10) of said filter body elements facing each other, wherein the filter body (2) defines an interior (5) of the filter element (1), wherein two filter body elements (7, 8) connected to each other as a pair are screwed together by means of internal and external threads (11, 12), which are formed on the end sections (9, 10) of said filter body elements and correspond with each other, and said filter body elements are additionallyadhesively bonded to each other in the contact regions thereof by means of an adhesive (13).

Description

technical field [0001] The invention relates to a filter element for filtering exhaust gas or process gas, in particular a filter cartridge having a filter body defining a longitudinal direction and divided along the longitudinal direction into a plurality of substantially tubular filter elements. Filter body elements, which are in each case connected in pairs at ends facing each other, the filter body delimits the inner space of the filter element. Furthermore, the invention relates to a method for producing such a filter element. Background technique [0002] Process gases or exhaust gases occur in the most diverse areas of industry, but also in everyone's daily life. Combustion equipment, gas turbines, waste incinerators, and internal combustion engines all have exhaust gases, to name a few. Due to environmental, safety and health requirements, these process or vent gases (commonly referred to as raw gases) must be cleaned or catalytically treated. Due to their product...
