APPARATUS FOR REDUCING PRESSURE FLUCTUATION

The present invention relates to a rotary pressure filter (10"'), comprising a filter housing (12), and a filter drum, wherein a plurality of treatment zones comprises at least a suspension insertion zone and a discharge zone, wherein the rotary pressure filter (10"') is configured such that a pressure being present in the suspension insertion zone is higher than a pressure being present in the discharge zone, and that, each time a filter cell, coming from the discharge zone and containing gas having the discharge zone's pressure, enters the suspension insertion zone, the pressure of the suspension insertion zone drops, characterized in that the rotary pressure filter (10"') further comprises equipment (44) that is configured to reduce and/or to slow the pressure drop of the pressure in the suspension insertion zone each time a filter cell coming from the discharge zone enters the suspension insertion zone. 本发明涉及一种旋转压滤机(10"')，其包括滤壳(12)和滤筒，其中多个处理区至少包括悬浮液引入区以及排出区，其中旋转压滤机(10"')被构造为使得悬浮液引入区中的压力高于排出区中的压力，并且在来自排出区且
