<p>PURPOSE:To suck and transport smoothly the dust blown off from a dust collecting section to a dust recovering line by establishing formation of air stream for sucking and transporting the dust from the inside of a casing to the dust recovering line and beginning air blow to the dust collecting section thereafter. CONSTITUTION:When dust cleaning instruction is dispatched, supply of power from a high voltage source 7 is first suspended and an air blow compressor 11 and a suction fan 15 are started simulataneously. Then, a suction damper 19 is opened when dampers 5, 6 of a casing 1 are closed to begin suction of air in the casing 1 toward the dust recovering line 16. Then, a main valve 18 of the air blow line 12 is opened at a specified time later to begin air blow. As the result, the dust collected in the dust collecting unit 9 is blown off by the start of the air blow; the blown-off dust is immediately dispersed into the air stream for transporting the dust which is already established in the casing 1, and transported smoothly to the dust recovering line 16.</p> |
