Abstract

System for separation of fluid-solid mixture from, for example, a mill. The mixture is introduced into a fluid-solid separator having a horizontally disposed cylindrical body portion, a tangential inlet adjacent one end of the body portion, and an outlet for separated solids adjacent the other end of the body portion. Suction means are mounted on the outlet end of the body portion and the inlet of the suction means serves to discharge the separated fluid from the horizontally disposed separator. A sifter for the separated solids can be disposed below the separator. The separated fluid, containing some entrained solids, can be introduced into a vertically disposed cyclone separator. The solids separated in the vertically disposed cyclone separator can be recycled to the inlet of the horizontally disposed separator. The use of a horizontally disposed separator according to the inventor reduces the headroom required.

Claims

1. Apparatus for separation of pneumatically conveyed solid from the conveying fluid comprising:

1. a horizontally disposed fluid-solid separator comprising;

a. a horizontally disposed hollow cylindrical body portion;

b. a tangential inlet conduit adjacent one end of the body portion;

c. an outlet for separated solids adjacent the other end of the body portion;

d. an outlet for discharge of separated fluid at said other end of the body portion;

2. a vertically disposed fluid-solid separator comprising;

a vertically disposed cylindrical body portion, a tangential inlet adjacent the upper end of the body portion, an outlet for separated solids adjacent the lower end of the body portion, and an outlet for discharge of separated fluid, the top of the vertically disposed separator being below about the top of the horizontally disposed separator;

3. an interconnecting conduit communicating the outlet for separated fluid of the horizontal separator with the inlet of the vertical disposed separator for delivery of the separated fluid of the horizontally disposed separator to the vertically disposed separator, for separation of solids entrained in the separated fluid of the horizontally disposed separator, 4. a blower disposed in said interconnecting conduit drawing suction on the horizontal separator for delivery of separated fluid of the horizontal separator to the vertical separator, 5. second conduit means communicating the outlet for separated solids of the vertically disposed separator, with the inlet conduit of the horizontally disposed separator intermediate the ends of the inlet conduit for recycling solids separated by the vertically disposed separator to the horizontally disposed separator, said second conduit means being in open communication with the outlet of the vertically disposed separator and the inlet conduit of the horizontally disposed separator.

2. Apparatus according tO claim 1, and means for receiving solids discharged from the outlet for separated solids of the horizontally disposed separator.

3. an interconnecting conduit communicating the outlet for separated fluid of the horizontal separator with the inlet of the vertical disposed separator for delivery of the separated fluid of the horizontally disposed separator to the vertically disposed separator, for separation of solids entrained in the separated fluid of the horizontally disposed separator,

4. a blower disposed in said interconnecting conduit drawing suction on the horizontal separator for delivery of separated fluid of the horizontal separator to the vertical separator,

5. second conduit means communicating the outlet for separated solids of the vertically disposed separator, with the inlet conduit of the horizontally disposed separator intermediate the ends of the inlet conduit for recycling solids separated by the vertically disposed separator to the horizontally disposed separator, said second conduit means being in open communication with the outlet of the vertically disposed separator and the inlet conduit of the horizontally disposed separator.
