Process for draining a fibrous pulp suspension |
摘要 |
A process for draining a fibrous pulp web is preferably carried out on drum thickeners or disk filters. A suspension to be drained rests against a perforated first face, which is a part of the rotor of the drum thickener or disk filter, is transported from the suspension vat, and then arrives in a thickening region. The thickening region contains a second face, wherein the first and second face have a relative speed in relation to each other. The effectiveness of the thickening can be significantly increased by vacuum zones provided on the drum thickener or disk filter.
