摘要
The present invention relates to an emission concentrator comprising a collecting cover (2) for collecting emission (3), and at least one emission guide conduit (4) opened in the collecting cover to discharge the collected emission (3). For the inflow of the emission (3), the collecting cover (3) has a collection opening part (6) facing a discharge position (5). The collecting cover (2) has a boundary barrier (8) forming the boundary with the side part (7) on at least one side part (7) of the collection opening part (6), and the boundary barrier is formed toward the center of an arch shape facing inside for each section, an angle facing inside, and/or the flowing emission introduced into the collection opening part (6). Thus, the emission concentrator can guide the emission in the outer side part (10) of the boundary barrier (8) toward the center of the flowing emission introduced into the collection opening part (6) through surrounding air (9) flowing in the outside of the boundary barrier (8) when the emission (3) is discharged. Also, the present invention relates to a tapping system (15) for a blast furnace comprising a tapping device arranged inside a blast furnace tank (16) and having a tapping hole (17); a channel (18) for storing pig iron after the pig iron is tapped; a molding platform (19) arranged above the channel (18); and the emission concentrator (1).;COPYRIGHT KIPO 2014
