化学制浆工段提出的常用浓黑液和稀黑液中含有较多纤维悬浮物，在进入碱回收工段之前，经过黑液过滤机转鼓上的滤网过滤出来，以免影响蒸发效率。本机没有黑液加温装置，以降低黑液粘度，保证过滤 机{gx}正常工作。
Deep Black liquor and dilute black liquor, that is taken out from chemical pulping section,enter into black filter press beford the alkali reycle ection,to prevent the fibers black liquor suspended objects to affect evaporation efficiency through thr turn drum net .The machine has black liquor heating device to reduce viscosity in order to ensure filter pres to efficient work normally.
