Abstract

PURPOSE: To prevent lowering of dust collecting capacity due to leaked air from a connector by a method wherein at least one of a valve apparatus for blocking a passage in a fixed duct and an inflow zone of sucked air is limited by said valve apparatus.
CONSTITUTION: A fixed duct 2 equipped with plural connectors 2' is arranged against coke ovens A, B and a dust collecting duct 1' of a coal charging car 1 is selectively connected to the connectors 2'. On the other hand, valve apparatuses 10A, 10B are arranged to both sides of a branched point of a duct part 7 to block a passage of the fixed duct 2 and a fork lever type limit switch 11 is arranged between the coke ovens A, B to change over the valve apparatus according to movement of the coal charging car 1. By the aforementioned valve apparatuses 10A, 10B, the valve apparatus 10B is blocked during a time when coal is charged to the coke oven A and leaked air from the connector 2 positioned at a right side from the apparatus 10B is interrupted.
