摘要： In a hydrocyclone the separation chamber (2) has a circumferential wall (3) provided with at least one turbulence creating member (12), which extends along the circumferential wall and crosses a helical path (10), along which a liquid stream is generated during operation. According to the invention, the turbulence creating member is formed by a set-off (12) on the circumferential wall (3). The set-off is formed and dimensioned such that said liquid stream substantially looses its contact with the circumferential wall, as the liquid stream passes the set-off. As a result turbulence is created in a layer of the liquid stream situated closest to the circumferential wall, without the liquid stream becoming any substantial flow component directed inwards in the separation chamber.

摘要： A hydrocyclone plant comprises a great number of hydrocyclones (1) arranged in groups of at least two hydrocyclones, each group being made in one single piece. The hydrocyclones extend substantially radially in an annular inlet space (11) for a liquid mixture to be separated. The inlet space extends concentrically around a cylindrical heavy fraction space (10) for receiving a created heavy fraction of the liquid mixture from the hydrocyclones. According to the invention, the hydrocyclone groups are distributed around the cylindrical heavy fraction space in the circumferential direction of the latter and are spaced from one another in the inlet space to allow the liquid mixture to flow between adjacent hydrocyclone groups.

摘要： Relatively heavy contaminants are separated from a contaminated pulp suspension by pumping the latter through a multihydrocyclone unit (6) having a multiplicity of hydrocyclones. Each hydrocyclone is provided with turbulence creating means adapted to counteract the formation of fibre network in radially outer liquid layers in the hydrocyclone. The pulp suspension separated from heavy contaminants is dewatered in a pulp wet machine (2). According to the invention, the fibre concentration of the pulp suspension which is fed into the multihydrocyclone unit (6) is at least 0,9 %.

摘要： Fine particles are separated from white water by the use of a disc filter, which comprises at least one rotating vertical filter disc (2), partly immersed in the white water to be separated, thereby sections (27) of the filter medium (5) of the filter disc are alternately displaced up from and down into the white water. When a section is displaced up from the white water it is covered by a cake containing fine particles which are detached in a detaching zone (16) before the section again is displaced down into the white water. According to the invention, each section is provided with a layer, solely containing fibres, in a forming zone (20) during each revolution and the section with its fibre layer is displaced through the white water in a separation zone (30), so that fine particles are deposited on the fibre layer and together with the latter form said cake.
