Abstract
An apparatus for bringing about coalescence of particles suspended in a liquid by means of a transverse velocity gradient in the liquid flow in a substantially vertical duct caused by friction against the walls defining said duct, the latter being formed by one or more tube or hose sections, consecutive sections being interconnected by bends, and the cross-section of said duct increasing either gradually or step-wise from the inlet towards the outlet end of said duct.
Claims4
In combination with gravitational separation apparatus for the gravitational separation of particles suspended in a fluid:
- fluid conduit means for causing the coalescence of particles suspended in a fluid in said conduit, including
- an inlet end in communication with a source of fluid,
- an outlet end in fluid communication with said separation apparatus for separation of particles in the latter by gravity, and
- means for increasing the collision frequency of particles in a fluid within said conduit including
- at least two vertically arranged sections in said conduit, said sections being of unequal cross-sectional area with, of any two sections, the one having the greater cross-sectional area being closer to said outlet end, and
- a "U" bend interconnecting said sections.
