Concial dust filter cartridges in powder coating processes

Powder coating is a coating process in which an electrically conductive material is coated with powder paint. Filtration Group Industrial’s customer manufactures equipment and systems for surface treatment with powder and wet paints, as well as paints and other liquid materials. Filtration Group Industrial selected an SFK-09 009 016 x 16 S1S SL 80 KA rectangular dust collector for the powder and wet paint coating application. A surface pre-treatment unit, an electronic coating zone and an intermediate and main dryer form the individual components of the coating system.

Challenge

The parts that need to be coated are guided with a conveying system during the treatment process. Typical undergrounds for the powder coating are steel, galvanized steel and aluminum. First the powder coating particles are fluidized. The powder needs to be cleaned up from fibers, coarse particles and dirt.

Technical data

  • Volume flow: 12.000 m³/h
  • Kind of dust: powder coating particles, fibers, rough particles and dirt
  • Temperature: max. 40 °C
  • Schedule in Zone 22 (ATEX)
  • Housing of 0 to – 56 mbar applicable
  • Dedusting depending on differential pressure using the MFS-07
  • Elements: in conical design, Filter material Ti 15 polyester
  • Surface: 15 m², DM 337 mm
  • Length: 1.100 mm

Solution statement

  • For this application, Filtration Group Industrial has used Quick Lock elements in conical design with a filter area of 15 m² in length 1,100 mm
  • For the fine dust, the filter material Ti15 achieved a high separation rate
  • The so-called “drawers” are used as dust collector to save construction high (Possibility increase of the clean gas space)
  • Redesign of the sound covers for separate installation besides the filter unit
  • Slanting outlet of the sound covers because of the requirement to blow out upwards preferably

Customer value

  • Cost-effective, compact design thanks to the possibility of small distances between the cartridges
  • Low overall height of the dedusting unit, by the use of Quick Lock mounting system
  • Effective cleaning by constant upstream velocity and reduced inside capacity(operation of multi-jet nozzle MJD)
  • Higher clean gas room for the connection of the clean gas pipeline
  • Optimal adaption of the dedusting unit to the customers surroundings
