Device for separating dust and dry-cleaning gas in the manufacture of iron or coal gasification

摘要

The device contains a supply pipe (1) for conducting the gas stream from the unit for the production of pig iron in a bun or units for the production of iron, which is pre-abatement equipment (2). Supply pipe (1) is branched at the point (3) branching to bypass pipe (4) and the primary gas pipeline (6). The device comprises at least one device (10, 11, 12) to remove dust. Primary pipe (6) is connected to the device (10, 11, 12) to remove dust by connecting pipe (7, 8, 9). The device (13) to adjust the temperature of the gas stream is arranged downstream from the device (10, 11, 12) for dust in the flow (1) or in the primary gas line (6). The device (14) to add the ingredients in the primary gas line (6) is located between the point (3) branching and the first connecting pipe (7, 8, 9) when viewed from the point (3) branching.
