摘要: A method of draining water from low-consistency water-fiber suspensions, in which the water-fiber suspension is fed to a filtering surface comprising holes. The rougher fibers are first separated from the water-fiber suspension and fed to the filtering surface to form a separate filtering layer and the water-fiber suspension is led to flow through the filtering layer formed by the rougher fibers.

摘要: In a papermaking process, filtering of white water containing fiber material is performed by feeding the white water to a filter on a surface of which a layer of auxiliary pulp has been formed, such that the white water is filtered through the layer of auxiliary pulp and fiber material in the white water remains in the layer of auxiliary pulp. The mixture of auxiliary pulp and fiber material is removed from the filter and is fed to a fractionating screen. The screen separates the mixture into a short-fibered pulp fraction that can be returned to the papermaking process, and a long-fibered pulp fraction that is returned to the filter where it is used as auxiliary pulp to form a layer on the filter surface.

摘要: The invention relates to a method of washing a fiber pulp mixture, in which method the fiber pulp mixture is fed between two filter wires running in the same direction. There is a convergent dewatering space in the direction of travel of the wires, where water is removed from the pulp. According to the idea of the invention, the thickness of the pulp layer being fed between the wires is adjusted during operation, since the ash and fines content of the washed fiber pulp is essentially dependent on the basis weight of the fiber web being washed. In a preferred embodiment of the invention, the height of the slice at the output end of the dewatering space is adjusted. The essential idea of another preferred embodiment of the invention is that the speed of the wires is adjusted. The invention also relates to an arrangement comprising means for adjusting the thickness of the pulp layer being fed between the wires, i.e. the basis weight of the fiber web being washed.

摘要: The invention relates to a method of draining a fiber pulp suspension, where the fiber pulp suspension is applied to a convergent dewatering space arranged between two wires travelling in the same direction. In the dewatering space, water and powdery substance are removed from the fiber pulp suspension through the wires. Pressure pulses are generated in the fiber pulp suspension along the length of the dewatering space with pressure pulse elements that are on opposite sides of the wires relative to the fiber pulp suspension and in contact with or at a distance from the wires. The invention also relates to an apparatus according to the method.
