Abstract: A chute receives contaminant gas-laden dust from a dust collector. At least one gas injector provides an upward flow of purge gas in the chute to release contaminant gas entrained with the dust. Downstream areas are maintained at positive pressure relative to upstream areas. A purge hopper arranged below the chute collects the dust. Dust handling apparatuses allow the upward flow of the purge and contaminant gases. Movable flaps in the dust handling apparatuses include perforations that may be capped to vary the gas flow rate. A dust discharge apparatus discharges washed dust from the purge hopper.
