  • Method and system for collecting paper dust
    Patent number: 8034192
    Abstract: Methods and systems for collecting dust produced in paper making involve an air inlet passage including an opening to receive dust laden air. The opening to the inlet passage may have a width approximately equal to a width of a paper web in a paper making machine. The air inlet passage is devoid of water injection. The dust collector may include a central vortex chamber and may be defined by an outer wall and an internal guide vane. There may be a water injector mounted in the outer wall and injecting water into the central vortex chamber, and there may be a discharge outlet of the central vortex chamber connectable to a water and air separator.
