HYDROCYCLONE UNIT AND METHOD FOR SEPARATING A FIBRE PULP SUSPENSION CONTAINING RELATIVELY HEAVY CONTAMINANTS |
摘要 |
A hydrocyclone unit for separating a fibre pulp suspension containing relatively heavy contaminants has an elongate tapering separation chamber, an inlet member that feeds the suspension tangentially into the separation chamber at a base end, so as to form a vortex in the separation chamber, a reject fraction outlet at the apex end of the separation chamber for discharging a reject fraction containing heavy contaminants, and a central accept fraction outlet at the base end for discharging a central fraction containing fibres. A fluid injection member is adapted to inject a fluid tangentially into the separation chamber at a distance from the apex end which is at least 40% of the length of the separation chamber, such that the injected fluid increases the rotational speed of a portion of the vortex in the chamber to increase the separation efficiency with respect to fibres existing in the vortex portion. |
