AI Technical Summary

Technical Problem

Existing centrifugal separators are difficult to effectively drive the turbine impeller when tilted, resulting in a degradation in performance and the inability to effectively clean gases containing liquid contaminants.

Method used

Designing the turbine housing has a residual kinetic energy structure higher than gravity energy, allowing liquid to form a pool and maintain kinetic energy in the turbine housing, ensuring that liquid can be ejected out of the housing efficiently, and enhancing the retention of liquid kinetic energy through the inclined inner surface and inner groove design. and guide.

Benefits of technology

The turbine impeller can be effectively driven even when the separator is inclined, ensuring the quality of the cleaning gas and improving the performance and efficiency of the centrifugal separator.

Abstract

The invention provides a centrifugal separator (1) for cleaning a gas containing contaminants. The separator comprises: a stationary housing (2) enclosing a separation space (3) through which a gas flow is allowed; a gas inlet (20) extending through the stationary housing (2) and allowing the supply of gas to be cleaned; a rotating member (7) comprising a plurality of separating members (9) arranged in the separating space (3) and arranged to rotate about an axis of rotation (X). The separator further comprises: a gas outlet (28) arranged in the stationary housing (2) and configured to allow discharge of the cleaned gas and comprising an outlet opening through a wall of the stationary housing (2); a discharge outlet (29) arranged in the stationary housing (2) and configured to allow the discharge of liquid contaminants separated from the gas to be cleaned. Furthermore, the separator comprises: a turbine housing (30) in which a turbine wheel (22) drivingly connected to the rotating part (7) is arranged; a nozzle (24) arranged for directing a jet of pressurized liquid towards the turbine wheel (22), thereby rotating the turbine wheel (22), in which the turbine housing (30) further comprises a turbine outlet (25) for discharging liquid for rotating said turbine wheel (22), and in addition, in which the turbine housing (30) has such a geometry that the nozzle (24) is arranged for directing a jet of pressurized liquid towards the turbine wheel (22), thereby rotating the turbine wheel (22). The turbine wheel (22) is arranged such that liquid used to rotate the turbine wheel (22) exits the turbine outlet with remaining kinetic energy higher than energy obtained individually from gravity.
