Centrifugal separator and method of separation Set of invention relates to centrifugal separator and method of control over boundary bed formed in separator chamber. Centrifugal separator comprises rotor defining separation chamber communicated with fluid mix inlet and having inner zone and radially outer zone. Note here that said zones contain separated light and heavy fluids. Said fluid form boundary bed in separation chamber. Rotor has space communicated with radially outer zone to keep separated heavy fluid. Said rotor incorporates control equipment including boundary zone level meter and device to feed adjustment fluid into said outer zone. Note here that proposed device incorporates pressure source composed of variable-rate pump to feed adjustment fluid, and adjustment fluid feed channel. One end of said channel communicates with pressure source. Another end communicates with adjustment fluid feed element. Adjustment fluid feed device allows discharging fluid from radially outer zone via the same channel used for adjustment fluid feed. Boundary bed level meter is connected with pump rate control device. Method of controlling boundary bed radial level comprises the steps whereat rotor is revolved, fluid mix is fed therein to be separated by centrifugal force in separation chamber. Note here that said centrifugal force make fluids form boundary bed inside separation chamber. Then, separated heavy fluid is fed in rotor space communicated with said radially outer zone to make heavy fluid fill it to form free surface with radial level corresponding to radial level of boundary bed in separation chamber. Thereafter, boundary bed level in separation chamber is defined. Then, adjustment fluid is fed into radially outer zone via space communicated with radially outer zone of separation chamber. Density of adjustment fluid exceeds that of said light fluid. Note here that adjustment fluid is fed into said space via adjustment fluid feed channel. Note also that adjustment fluid is fed into amount in unit time required to prevent displacement of boundary bed formed in separation chamber between separated light and heavy fluids or adjustment fluid radially outward from preset outer radial level. Then, fluid is discharged from radially outer zone of separation fluid in amount in unit time required to prevent displacement of boundary bed radially inward from preset inner radial level in feed of surplus heavy fluid. |

Method of hydrodynamic cleaning of sediments from centrifugal fluid cleaner and device to this end Invention relates to separation of emulsions in the filed of centrifugal forces and may be used for cleaning oil products and process fluids from impurities. Proposed method comprises transfer of impurities into suspended state. Note here that cap is axially shifted and locked relative to rotor as dirt accumulates on its wall. Thereafter, fluid is swirled by rotor to wash off dirt to be transferred into suspension to be removed from cleaner. Centrifugal cleaner comprises encased hollow shaft with feed and discharge branch unions and pressure disc fitted at sediment collector and communicated therewith. Besides, it comprises rotor including plate holder with top and bottom impellers and stack of conical plates arranged there between, and cap with plug mounted on said rotor. Said cleaner is furnished with seal and cap axial displacement and locking drive. |

Plant and method for separation oil from gas mix Set of invention relates to cleaning. Proposed plant comprises gas tube and centrifugal separator located thereat and comprising stationary case with gas separation chamber, gas mix inlet, and gas mix separation element. The latter has multiple separation discs. Central outlet chamber is located inside said separation discs in separation area. Proposed plant comprises drive motor coupled via shaft with separation element to revolve it about rotational axis. Note here that said separation element separated oil from gas mix by centrifugal forces. Gas outlet is located downstream of separation element and directly connected therewith by central outlet chamber for discharge of separated gas. Oil discharge opening extends through aforesaid case, Note here that said case withstands separation pressure of, at least, 10 bar. Plant allows counterflow separation so that gas mix is revolved and directed into separation element radially outward and to center and to central outlet chamber. In compliance with proposed method, gas mix is fed into separation area via inlet. Note here that pressure of, at least, 10 bar prevails in separation area. Thereafter, gas mix is revolved and displaced radially from outside via separation element. Note here that oil is separated from gas mix by centrifugal forces. Note also that separation elements revolves at definite rpm. Thereafter, separated gas is discharged from central outlet chamber via gas outlet while oil is discharged via oil outlet extending through the case. |
