摘要：Fibrous-type filters are used to capture dust particles in mining and other occupations where personnel are exposed for pro-longed periods.Dust cleansing devices including flooded-bed dust scrubbers use these mesh-type multi-layered filters.These filters trap dust particles efficiently on their surface and inside their mesh.However,their continued operation leads to dust build-up and clogging.This results in increased resistance of the filter and lowered airflow rate through the scrubber.This could potentially enhance the exposure of the miners.A non-clogging self-cleaning impingement screen type dust filter was designed by the authors for use in mining and industrial dust cleansing applications.The filter guides dirt-laden air through rapidly turning paths which forces it to shed heavier particles.The particles impact one of the impermeable solid metallic filter surfaces and are removed from the airstream.A full cone water spray installed upstream prevents any surface build-up of dust.This paper summaried the computer models generated to show the filter operations and laboratory experiments including optical particle counting to establish the cleaning efficiency.
