METHOD OF PREVENTING DUST EMISSION DURING CONVEYANCE OF PARTICULATE MATTER

摘要

PROBLEM TO BE SOLVED: To provide a method of preventing dust emission during conveyance of a particulate matter, for efficiently and economically preventing dust emission of the particulate matter without using a large amount of bubbles.;SOLUTION: When the particulate matter 11 is conveyed using conveying devices 13, 14, bubbles are supplied onto loading surfaces 25, 26 of the conveying devices 13, 14 before the particulate matter 11 is loaded in the conveying devices 13, 14. A chute 15 having a slope 29 inclined downward with respect to a horizontal direction within a range which exceeds an angle of repose of the particulate matter 11 and is equal to or less than 85° is arranged in a transfer part between the conveying devices 13, 14 which adjoin each other in the conveying direction of the particulate matter 11, and a storage hopper 12 which has a slope 27 inclined downward in the conveying direction of the particulate matter 11 and whose angle θ1 of inclination is set to be downward with respect to the horizontal direction and within a range which exceeds the angle of repose of the particulate matter 11 and is equal to or less than 85° is arranged upstream from the conveying device 13, so that the particulate matter 11 slides down along the slopes 29, 27.;COPYRIGHT: (C)2012,JPO&INPIT
