Abstract
For obtaining coalescence of particles suspended in a carrier liquid, a plurality of relatively small bodies are circulated in a closed cycle together with a part of the suspension, and in the narrower interspaces between said bodies and on the surfaces thereof the probability of particles meeting one another is increased. Carrier liquid with suspended coalesced particles is continuously withdrawn from the closed cycle, and fresh liquid is continuously introduced therein, the circulating movement of the bodies being maintained either by the kinetic energy of the introduced liquid or by injecting an auxiliary driving medium into the liquid flow.
Claims4
A device for promoting the separation of a liquid to be treated, wherein said liquid includes components suspended therein, by coalescing said components, comprising:
- a substantially vertically-oriented chamber, having an inlet at its upper end for continuously admitting the liquid to be treated and a first outlet at its lower end for discharge of a more dense component and a second outlet near its upper end for discharge of a less dense component;
- a plurality of minute bodies suspended in the chamber throughout the liquid, said bodies of a material which is chemically inert to the liquid;
- a first grid near the bottom of said chamber above said first outlet and below said second outlet, extending across said chamber for preventing said bodies from being discharged through said first outlet;
- a second grid disposed across said second outlet to prevent said bodies from being discharged through said second outlet;
- and
- a jet mounted in the lower portion of said chamber above said first grid and below said second outlet, for discharging a compressed gas into the liquid to cause the liquid and said minute bodies to circulate together continuously within said chamber.
