ABSTRACT:
A recycling mechanism is provided for use with a compact dedusting apparatus to clean the contaminate-laden air discharged from the dedusting apparatus for subsequent re-use by the dedusting apparatus. The recycling mechanism provides a closed loop air containment system that retains the air within the apparatus without providing discharge to the atmosphere. The recycling mechanism includes a cyclonic separator that removes most of the dust and contaminates from the air discharged from the deduster. The air discharged from the cyclonic separator is passed to an inline high efficiency synthetic cartridge filter for final cleaning before being passed back into the fan that drives cleansing air through the deduster. The contaminant material removed by the cyclonic separator is collected by an air tight dust collection container installed at the cyclone outlet for subsequent removal from the system.
