[Also in Division C1] Water containing suspended soot is fed via inlet 4 into the space between a cylindrical casing 1 and a rotating cylinder 2 to which is fixed an agitator 3. An agglomerating agent, e.g. a heavy oil, is added through a inlet 5. Water and agglomerated impurities flow past a baffle 6, which ensures that some of the agglomerated impurities are always present in the space between casing 1 and cylinder 2, through an outlet 7 and onto a filter 8 from which separated impurities flow through a discharge 10, e.g. a tube or gutter, and water flows through a discharge 9. The concentration of suspended impurities in the discharged water is measured by a photometric device 12 and compared with an arbitrary valve by a device 13 the output of which actuates a device 14 incorporating a timing mechanism to regulate the flow of agglomerating agent through a valve 15. If the concentration of suspended impurities exceeds the set value, discharged water may be recirculated. The rotatable cylinder may have a hollow portion (25), Fig. 3 (not shown), having vanes (26) and slits (27) through which the water and agglomerated impurities pass into an apertured tube (28) and into a compartment (30) of the casing (23) formed by a partition (29). Agglomerated impurities may be discharged from the space between the rotatable cylinder and the casing (23) through an outlet (32).</p> |
