but, for known what chvorri chtungen a substantial difficulty in the need to adapt to the significant fluctuations occurring during operation of the operating pressure of the gas, eg _o a blast furnace sealing gas over a wide range. The narrowed section of the nozzle gas washer must be designed in such a way that the full gas volume can always flow under the lowest possible gas pressure. On the other hand, the gas washer must always absorb a maximum flow energy when large amounts of gas arise. The scrubber must therefore operate over a very wide range of gas pressures under uniform conditions.

In the case of nozzle gas scrubbers η, dust or sun is deposited chemical contaminants a from the gas one or more fine spray jets of a cleaning liquid into the Sprayed gas stream. The liquid can either Water or, in the removal of ancient Aryan impurities, also be a Löjun ^ j of chemicals.

Each nozzle 38 is connected via a pipe 44 to a collecting pipe 42 which lies around the section 24 and in turn is connected via a pipe 46 (FIG. 3) to a main water supply (not shown). The nozzle 38 protrudes inward through an opening 48 in the wall 40 and is encapsulated in a short tube 50 which runs from the opening 48 to a flange 52, to which a corresponding flange 54 of the nozzle 38 is attached. The nozzle 38 has a housing 56 in which a passage 58 is provided, which leads horizontally from the pipe 44 into a chamber 60 which projects upwards from the passage 58 and towards the interior of the line section 34, where the mouthpiece 32 projects downwards attached to the downward facing edge of the chamber 60. When the device is in operation, the water flows from the line 44 through the passage 58 into the chamber 60 and is sprayed obliquely downward from the mouthpiece 62. The tube 44 is attached to the flange 54. A plate 78 is fastened between the flanges 52 and 54 and has a bore 80 that corresponds to the tube 50. If the nozzle 38 has to be removed, for example for war tang, a section 32 of the plate 73 is fastened over the flange 52 so that the tube 50 is closed. A valve 84 is provided in the line 44 near the nozzle and the jam tube 42.
