| 摘要 |
The invention concerns an industrial filtering device for deodorising gas comprising a housing (1) and filtering means (2) arranged inside it (1), characterised in that the filtering means comprise a cylindrical internal column (2) which is subdivided into various filtering sections (21; 22) by partitions (94), filtering cartridges (8) capable of being inserted in said filtering sections (21; 22), each filtering cartridge (8) comprising a rigid fixing frame (30) clamping at least one removable retaining screen (9) encasing at least one filtering material (30, 12) between them having low resistance to the currents formed by the flowing gases to be deodorised and a density such that the odorous particles present in the gases to be treated are retained. The invention also concerns a filtering method and a method for renewing the elements constituting the filter. |
