摘要： The present invention relates to a filtering method, in which the suspension to be filtered is passed into contact with the filtering surface of the filter element, whereby due to the pressure difference prevailing across the filtering surface the filtrate flows through the filtering surface and separated solids substantially remain in the suspension. According to the invention the suspension to be filtered is passed to flow downwards along the filtering surface, whereby the filtering through the filtration surface takes place from the falling film and the separated solids are discharged with the falling film without forming a harmful solids layer on the filtering surface. An even liquid film falling on the filtering surface is generated by recirculating suspension from the bottom of the filter to the upper part of the filter element. The invention also relates to an apparatus for realizing the method, which may be applied especially for clarifying green liquor.
摘要翻译：本发明涉及一种过滤方法，其中将待过滤的悬浮液与过滤元件的过滤表面接触，由此由于过滤表面上的压力差，滤液流过过滤表面并分离出固体基本上保留在悬浮液中。根据本发明，待过滤的悬浮液被传递以沿着过滤表面向下流动，由此通过过滤表面进行过滤从降膜发生，并且分离的固体与降膜一起排出，而不形成有害固体层过滤面。落在过滤表面上的均匀的液膜通过从过滤器的底部向过滤元件的上部再循环悬浮液而产生。本发明还涉及一种用于实现该方法的装置，其特别可用于澄清绿液。

摘要： PCT No. PCT/CH90/00100 Sec. 371 Date Dec. 18, 1990 Sec. 102(e) Date Dec. 18, 1990 PCT Filed Apr. 10, 1990 PCT Pub. No. WO90/12634 PCT Pub. Date Nov. 1, 1990.In relation to time intervals or pressure loss, the successive flushing via the same flushing channel (10) of several filter elements (7) is brought about by the direct sweeping of the internal surface of said elements (7) by the fluid to be filtered. It comprises a tubular body (1) and an upstream distribution plate (4), each feeding a filter element (7) extending axially inside the body, and a downstream aperture. At its downstream end there is a distributor comprising several inlets linked to the downstream end of the elements (7), said inlets being linked by channels (22) to a single outlet, itself linked to a flushing branch pipe (8) opening laterally outside the body (1). This distributor comprises a rotor (18) which, depending on its angular position, separately connects each of its inlets to the shared outlet of distributor.
