Abstract
Process gas purification device (2) for a melt reduction system (1) comprising at least one reduction reactor (3) and a melting gasification reactor (4), a first line system (5) for discharging a furnace gas (6) from the reduction reactor (3) and a second line system (7) for discharging a generator gas (8) from the melting gasification reactor (4) wherein both line systems (5,7) lead to a respective wet scrubbing system (11, 12). The furnace gas or generator gas flow can be throttled preferably by way of a control element (41) that varies a control gap (40) and the scrubber or cooling liquid (49) can be collected and drained. The first wet scrubber system (11) of the first line system (5) for routing the furnace gas (6) and the second Venturi scrubber system (12) of the second line system (7) for routing the generator gas (8) both discharge into a common mist elimination device (14).
