Abstract
A centrifugal separator apparatus and method for improving the efficiency of the separation of constituents in a fluid stream. A cyclone separator includes an assembly for separately discharging both constituents through the same end of the separator housing. A rotary separator includes a rotary housing having a baffle disposed therein for minimizing the differential rotational velocities of the constituents in the housing, thereby decreasing turbulence, and increasing efficiency. The intensity of the centrifugal force and the time which the constituents reside within the housing can be independently controlled to improve efficiency of separation.
Claims12
An apparatus for separating constituents from a fluid stream including a first lower density or mass constituent and a second higher density or mass constituent, said apparatus comprising:
- a rotating cylidrical housing, said housing defining a longitudinal axis and having an inlet opening at one end and an outlet opening at the other end, means for introducing said flowing stream into said housing, means for rotating said housing to cause the rotation of the flowing stream within said housing and producing a centrigugal force causing the first constituent to migrate radially inwardly towards the longitudinal axis of said housing and axially downwardly towards and through said outlet opening and the second constituent to migrate radially outwardly towards said housing and axially downwardly towards and through said outlet opening simultaneously with the first constituent, an elongated baffle in said housing for reducing the turbulence of the flowing stream, said baffle extending radially through the longitudinal axis of said housing and dividing said into a plurality of compartments, and outlet means in communication with said outlet opening for separately discharging the first and second constituents.
An apparatus for separating constituents from a fluid stream including a first lower density or mass constituent and a second higher density or mass constituent, said apparatus comprising:
- a rotating cylindrical housing, said housing defining a longitudinal axis and having an inlet opening at one end and an outlet opening at the other end, means for introducing said flowing stream into said housing, means for rotating said housing to cause the rotation of the flowing stream within said housing, the rotation of the stream producing a centrifugal force causing the first constituent to migrate radially inwardly towards the longitudinal axis of said housing and the second constituent to migrate radially outwardly towards said housing, an elongated baffle in said housing for reducing the turbulence of the flowing stream, said baffle extending radially through the longitudinal axis of said housing and dividing said housing into a plurality of compartments, outlet means in fluid communication with said outlet opening for separately discharging the first and second constituents, and a splitter attached to said housing at said outlet end and rotatable therewith, said outlet means comprising a first member cooperating with said splitter, and a second member, the first constituent being discharged through said splitter and said first member and the second constituent being discharged through said second member.
An apparatus for separating constituents from a fluid stream including a first lower density or mass constituent and a second higher density or mass constituent, said apparatus comprising:
- a rotating cylindrical housing, said housing defining a longitudinal axis and having an inlet opening at one end and an outlet opening at the other end, means for introducing said flowing stream into said housing, means for rotating said housing to cause the rotation of the flowing stream within said housing, the rotation of the stream producing a centrifugal force causing the first constituent to migrate radially inwardly towards the longitudinal axis of said housing and a second constituent to migrate radially outwardly towards said housing, an elongated baffle in said housing for reducing the turbulence of the flowing stream, said baffle extending radially through the longitudinal axis of said housing and dividing said housing into a plurality of compartments, outlet means in fluid communication with said outlet opening for separately discharging the first and second constituents, and a splitter attached to said housing and said outlet end and rotatable therewith, said outlet means comprising a first member cooperating with said splitter, and a second member, the first constituent being discharged through said splitter and said first member and a second constituent being discharged through said second member, said first member being an elongated pipe, said splitter and said pipe being co-axial with said housing, and said second member being a sluice co-axial with and surrounding said outlet opening of said housing.
A method of separating first and second constituents from a fluid stream including a first lower density or mass constituent and a second higher density or mass constituent, said method comprising the steps of:
- introducing the flowing stream into a cylindrical housing, said housing defining a longitudinal axis and having an inlet opening at one end and an outlet opening at the other end, rotating said housing to cause the rotation of the flowing stream in said housing, the rotation of the flowing stream producing a centrifugal force causing the first constituent to migrate radially inwardly towards the longitudinal axis of said housing and the second constituent to migrate radially outwardly towards said housing, varying the intensity of the centrifugal force, discharging the first and second constituents separately and simultaneously through said outlet opening, and varying the rate of the flowing stream flowing through said inlet opening and the rate of the first and second constituents flowing through said outlet opening to control the time which the flowing stream resides within said housing.
