Venturi washer for blast furnace gas - partic. for high pressure furnaces, incorporating mist sepn., sound damping and top gas pressure control

摘要

The venturi washer comprises a single Venturi tube, a vertical mist separator chamber surrounding the discharge section and a sound damper installed in a space delimited by the external peripheral surface of the discharge section and the internal peripheral surface of the wall of the mist sepg. chamber. The washer permits control of the top gas outlet pressure of the blast furnace and washing of the gases with subsequent mist and dust removal as well as sound damping both in the Venturi throat and in the mist sepg. chamber.
