METHOD FOR DISCHARGING DUST FROM DUST COLLECTOR

摘要

PURPOSE:To surely discharge dust without causing the hanging phenomena of dust by allowing dust incorporated in a dust removal chamber to flow down to a dust bin side in such a state that it is slightly pressurized. CONSTITUTION:Pressure equalization is stopped in such a state that the inside of a dust pin 6 is pressurized to the pressure a little lower than the inside of duct removal chambers 1 by opening and closing a pressure equalizing valve 9 provided to a pressure equalizing gas flow path 8 communicating between the dust removal chambers 1 and the dust bin 6. Dust incorporated in the chambers 1 is allowed to flow down into the dust bin 6 by opening the controlling means 4for discharging the dust removal chambers in this state. As a result, dust 7 incorporated in the chambers 1 is allowed to flow down to the dust bin 6 side in a slightly pressurized state and dust 7 is surely discharged without causing a hanging state inside of the chambers 1.
