Abstract
Abstract A separator comprises a vessel having an outer wall (2) and an end wall (3). A body (14) adjacent the end wall (3) defines with the end wall (3) an annular opening (15). In use, a mixture of, for example water and solid material is introduced into the vessel through a first inlet (4). A circulating motion takes place in the vessel and the solid material falls to the end wall (3) and is removed through the opening (15) to an outlet (6) while clean water flows from the top of the vessel through an outlet (8). In order to increase the energy in the lower region of the vessel so as to assist removal of the solid material, water from the outlet (8) is passed through a pump (P) and reintroduced as energising fluid to the vessel through a recirculating port (44). Energising fluid may be taken from sources other than the outlet (8). Various alternative forms of separator are disclosed.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
101 words
A separator for operation at low energy, comprising a vessel (1) having a cylindrical outer wall (2) and an end wall (3) at one end, a body (14) being provided in the vessel (1) and defining with the end wall (3) an annular opening (15) which is spaced from the outer wall (2), the vessel (1) being provided with an inlet (4) for introducing a fluid into the vessel, characterized in that energizing means (44) is provided for imparting energy to fluid in the vessel (1) in a manner to create or enhance rotational movement of the fluid within the vessel.
Claim 2
Dependent Claim
103 words
A separator for operation at low energy, comprising a vessel (1) having a cylindrical outer wall (2) and an end wall (3) at one end, a body (14) being provided in the vessel (1) and defining with the end wall (3) an annular opening (15) which is spaced from the outer wall (2), the vessel (1) being provided with a first inlet (4), for introducing a fluid into the vessel, characterized in that a second inlet (44) is provided for introducing an energising fluid into the vessel (1) in a manner to create or enhance rotational movement of fluid within the vessel (1).
Claim 3
Dependent Claim
45 words
A separator as claimed in claim 2, characterized in that the first inlet (4) is directed tangentially of the outer wall (2) thereby to create the rotational movement within the vessel (1), the energising fluid flowing through the second inlet (44) enhancing this rotational movement.
Claim 4
Dependent Claim
31 words
A separator as claimed in claim . 2 or 3, characterized in that at least one of the inlets (4,44) is provided in the outer wall (2) of the vessel (1).
Claim 5
Dependent Claim
34 words
A separator as claimed in any one of claims 2 to 4, characterized in that the first and second inlets (4,44) are provided at different positions along the axis of the outer wall (2).
Claim 6
Dependent Claim
34 words
A separator as claimed in claim 5, characterized in that the axis of the outer wall (2) is substantially vertical, and in which the first inlet (4) is disposed above the second inlet (44).
Claim 7
Dependent Claim
38 words
A separator as claimed in claim 6, characterized in that the first inlet (4) is at or above a position halfway down the vessel (1) and the second inlet (44) is disposed at or below that halfway position.
Claim 8
Dependent Claim
27 words
A separator as claimed in any one of claims 2 to 7, characterized in that the second inlet (44) is disposed close to the end wall (3).
Claim 9
Dependent Claim
31 words
A separator as claimed in any one of claims 2 to 8, characterized in taht means (40) is provided for imparting momentum to the fluid passing through the second inlet (44).
Claim 10
Dependent Claim
19 words
A separator as claimed in claim 9, characterized in that the means (40) for imparting momentum is a pump.
Claim 11
Dependent Claim
49 words
A separator as claimed in any one of claims 2 to 10, characterized in that the energising fluid is the same fluid as passes to the first inlet (4), the energising fluid being diverted to the second inlet (44) from the supply of fluid to the first inlet (4).
Claim 12
Dependent Claim
37 words
A separator as claimed in any one of claims 2 to 10, characterized in that the energising fluid is taken from the fluid within the vessel (1) and reintroduced into the vessel through the second inlet (52).
Claim 13
Dependent Claim
23 words
A separator as claimed in claim 12, characterized in that the energising fluid is taken from the outlet flow (8) from the vessel.
Claim 14
Dependent Claim
26 words
A separator as claimed in claim 12, characterized in that the energising fluid is taken from a recirculation port (58) provided in the outer wall (2).
Claim 15
Dependent Claim
36 words
A separator as claimed in any one of the preceding claims, characterized in that the annular opening (15) is the mouth of an annular channel (48) defined between the body (14) and the end wall (3).
Claim 16
Dependent Claim
32 words
A separator as claimed in claim 15, characterized in that the base of the channel (48) comprises the surface of a member'(46) which connects the body (14) to the end wall (3).
Claim 17
Dependent Claim
22 words
A separator as claimed in claim 15, or 16, characterized in that the annular channel is provided with an outlet port (50).
Claim 18
Dependent Claim
112 words
A separator for operation at low energy for separating components of a fluid mixture, comprising a vessel (1) having a cylindrical outer wall (2) and an end wall (3) at one end, a body (14) being provided within the vessel (1) and being connected to the end wall (3) by a member (46) characterized in that the member (46) has an outer surface which surrounds the axis of the vessel (1), the body (14) projecting radially outwardly beyond the outer surface of the member (46) so that the body (14), the member (46) and the end wall (3) define an annular channel (48), this chanel being provided with an outlet opening (50).
Claim 19
Dependent Claim
