Abstract
The present invention provides a fluidizing unit (1) for use in a vessel desanding system, comprising a discharge pipe (2) and a supply duct (3), the discharge pipe comprises a discharge inlet (4) and a discharge outlet (5), and the supply duct is formed by a housing (6) arranged around the discharge pipe defining an annular space (7) between an outer surface of said pipe and an inner surface of the housing, the supply duct comprises a pressurized liquid inlet (8) and a pressurized liquid outlet (9), wherein the pressurized liquid outlet, during use, is able to provide a pressurized liquid flow having a substantially elliptic cross-section.
Claims10
A fluidizing unit (1) for use in a vessel desanding system, comprising a discharge pipe (2) and a supply duct (3), the discharge pipe comprises a discharge inlet (4) and a discharge outlet (5), and the supply duct is formed by a housing (6) arranged around the discharge pipe defining an annular space (7) between an outer surface of said pipe and an inner surface of the housing, the supply duct comprises a pressurized liquid inlet (8) and a pressurized liquid outlet (9), wherein the pressurized liquid outlet, during use, is able to provide a pressurized liquid flow having a substantially elliptic cross-section.
A fluidizing unit according to any of the preceding claims, wherein the cross-section of the housing (7) and the discharge pipe (2), in a plane being substantially perpendicular to a centerline of the discharge pipe, is circular at the pressurized liquid inlet (8).
A fluidizing unit according to any of the preceding claims, wherein the cross-section of the housing (7) and the discharge pipe (2), in a plane being substantially perpendicular to a centerline of the discharge pipe, is elliptic at the pressurized liquid outlet (9).
A fluidizing unit according to any of the preceding claims, wherein the pressurized liquid outlet comprises an annular flange (10) arranged close to the discharge inlet (4), such that pressurized liquid exiting the outlet during use is led in a direction being substantially perpendicular to the centerline of the discharge pipe.
A fluidizing unit according to any of the preceding claims, wherein the discharge inlet (4) has an elliptic cross-section, the major axis of said cross-section aligned with the major axis of the elliptic cross-section of the pressurized fluid outlet (9), or the elliptic cross-section of the pressurized liquid flow.
A fluidizing unit according to any of the preceding claims, wherein the pressurized liquid inlet (8) is arranged such that pressurized liquid will enter off-center to the centerline of the discharge pipe (2) during use, causing said liquid to swirl around said pipe.
A vessel desanding system comprising a vessel and at least one fluidizing unit according to any of the preceding claims, wherein said unit is arranged within the vessel having the pressurized fluid outlet (9) close to the bottom of the vessel, and such that the major axis of the elliptic cross-section of the pressurized liquid flow is aligned with a longitudinal axis of said bottom.
