A 3D-visualisation is the perfect solution to represent details, processes, operations and reactions within a filtering installation. The complex processes of a dust removal process using a bag filter are communicated in 3D-visualisation easily and clearly understandably. The functions and process steps of the dust removal are clearly shown in the 3D-visualisation. A bag filter of the series ProJet mega is shown. The technology contained in it, e.g., the cleaning using the coanda injector, the particle flow in the raw gas duct and clean gas duct and the dust discharge are explained in detail. Everything on dust removal with a bag filter revolves here:
