摘要

The device for suction of filling emissions of an elevated railway bunker construction of a blast furnace operation, comprises a stationary exhaust collecting pipe (2) and a bridging carriage (4) displaceable along a bunker array of the bunker construction. The bridging carriage consists of bunkers (3) and a suction line (5) for the filling emissions, which are attached to the collecting pipe. The bridging carriage joins the emissions and discharges at a central transfer point (6) into the collecting pipe. A stationary emission-gathering dome (8) mountable on a bunker array is provided. The device for suction of filling emissions of an elevated railway bunker construction of a blast furnace operation, comprises a stationary exhaust collecting pipe (2) and a bridging carriage (4) displaceable along a bunker array of the bunker construction. The bridging carriage consists of bunkers (3) and a suction line (5) for the filling emissions, which are attached to the exhaust collecting pipe. The bridging carriage joins the emissions and discharges at a central transfer point (6) into the exhaust-collecting pipe. A stationary emission-gathering dome (8) mountable on a bunker array is provided and conducts the emissions from the bunkers into the suction hose. A bridging box (9), which is operated and led on the emission-gathering dome is arranged on the bunker side end of the suction line and balances a vertical and horizontal packing between the bunker array and the suction line. The bridging boxes are provided with wheels or rollers, which run on a track system arranged on the emission-gathering dome. Slide seal rings are provided for the sealing of the connecting area of the bridging boxes and suction line. The bridging carriage slides during a displacement movement along the exhaust collecting pipe, so that the central transfer point relocates to the position of the carriage. The exhaust collecting pipe is provided with a longitudinal opening, which is sealed outside of the transfer point. The bridging carriage is loaded and led on the exhaust collecting pipe and/or on the emission-gathering dome and/or directly on the elevated railway-bunker construction, and is regulated over the suction lines, between which sheet metals are mounted.
