Abstract

An inlet mechanism (2) for a cyclone gas/oil separator (6) adjustably controls the size of the inlet. The mechanism comprises an assembly of a baffle (20) and a rack (18) and pinion (16), the baffle being moveable by the rack and pinion. The assembly is suitable for installation at the inlet of the cyclone separator whereby the movement of the baffle to vary the size of the inlet can be effected from the exterior of the cyclone. <IMAGE>

Description

SPECIFICATION Improved inlet mechanism for cyclone separator This invention relates to an inlet mechanism for a cyclone separator, more particularly to a cyclone for separating oil and gas.
Cyclone separators having an inlet by means of which the mixture of oil and gas to be separated is introduced tangentially with respect to the walls of the separator have been previously described in our copending UK Patent Applications Nos.
2000054A; 200711 8A; 20351 50A; and European Patent Applications Nos. 0018168 and 0024148.
To obtain a suitable inlet velocity over a wide range of fluid imputs these earlier patents disclose that the inlet should be controllable and describe a baffle assembly which works to provide a smoothly converging path for the feed mixture.
An improved inlet control mechanism has now been devised.
Thus, according to the present invention an inlet mechanism for a cyclone separator for adjustably controlling the size of the inlet comprises and assembly of a baffle and a rack and pinion, the baffle being moveable by the rack and pinion, the assembly beingasuitable for installation at the inlet of a cyclone separator whereby the movement of the baffle to vary the size of the inlet can be effected from the exterior of the cyclone separator.
The inlet mechanism can conveniently be enclosed in a housing which can be attachable to the cyclone separator by any convenient means or method such as welding.
The invention also comprises a cyclone separator having an inlet mechanism as hereinbefore described.
The cyclone separator is preferably provided with a substantially flat wall against which the feed mixture is in use directed by the baffle of the inlet mechanism.
Preferably the flat wall and the baffle are disposed so that the plane of the baffle intersects that of the flat wall.
The baffle can be in the form of a flat plate and the inlet pipe of the cyclone separator can be provided with flat surfaces which, with the flat plate and the flat wall of the cyclone separator against which the feed mixture is, in use, directed by the flat plate, provide a passage of rectangular cross section for the feed mixture.
The invention is illustrated by the accompanying drawings in which: Figure 1 is a horizontal section of the cyclone and inlet where the inlet mechanism is arranged to cause the inlet mixture to be directed tangentially with respect to the wall of the cyclone, and Figure 2 is a section through the line A-A of Figure 1.
The inlet mechanism indicated generally by numeral 2 works in a circular inlet pipe 4 welded to the walls of a cyclone separator 6 at welds 8.
The circular inlet pipe 4 has filling pieces 10 welded to the interior to provide flat sides.
The inlet mechanism 2 comprises a rotatable shaft 12 working within a sleeve 1 3 both being enclosed within a cylindrical housing 14 which extends through and is welded to the wall of the inlet pipe 4. The end of the shaft 12 is provided with a pinion 1 6 which engages rack 18, to which is attached a baffle in the form of plate 20 which is movable on and supported by guide rails 22. The guide rails 22 are welded to filling pieces 10 which provide flat sides for the inlet.
The inward end of the shaft 12 is sealed against the sleeve 1 3 by a pair of 0 ring seals 24. An end plate 26 covering the end of the shaft 12 and pinion 16 is held by a screw 28.
A locking device 36 is provided to lock the mechanism in a selected position.
The shaft 12 and sleeve 13 are secured in position by means of a flange 30 (which is welded to the sleeve 1 3) and bolted to flange 32.
Unbolting of flanges 30 and 32 enables the assembly of shaft, sleeve, flange 30, locking device 36, turning handle 34 and pinion 1 6 to be withdrawn for inspection.
In use rotation of the shaft 12 causes pinion 1 6 to turn and move rack 1 8 and causes baffle plate 20 to move forward or backward along a linear path. The cylone wall is provided with a wear plate 40 and the wall 42 against which the feed is directed by the baffle plate 20 is of a substantially flat shape.
The advantages of the above described mechanism are that: (i) fine adjustment of the inlet is obtainable so that efficient operation of the cyclone can be achieved over a wide range of throughputs, (ii) the mechanism can be locked in a selected position, (iii) a tangential flow of inlet fluid is achieved, (iv) the effect of the filling pieces 10, together with the flat baffle plate 20 and flat wall 42 is to provide a flat sides, e.g. rectangular, passage for the feed mixture.
