摘要
PCT No. PCT/FI90/00094 Sec. 371 Date Dec. 5, 1991 Sec. 102(e) Date Dec. 5, 1991 PCT Filed Apr. 6, 1990 PCT Pub. No. WO90/11809 PCT Pub. Date Oct. 18, 1990.The invention relates to a continuous-working process and apparatus for replacing the liquid in a liquid suspension of a fibrous material with another liquid by forming of this material a bed on a moving filter surface and by displacing the liquid present in this bed with the other liquid. The bed of material is formed on a cylindrical filter surface installed in a vertical orientation below the liquid surface in a container and conveys it continuously forward filtration and several successive liquid displacements effected by maintaining a hydrostatic pressure difference across the formed bed, which is conveyed continuously horizontally forward, and through it there flow liquids horizontally during the filtration and liquid displacement.
