The system can meet all the needs in pumping, cleaning, deaeration
and screening of the stock..
Five branch systems, they are:
1. Cleaning system:
Using heavy rejects cleaning system with one grade more stage.
2. Deaeration system:
Including Deaerator, Condenser, Vacuum Pump, Steam-water Separator
and silencer etc.
3. Screening system:
Including low pulse pressure screen and tailings screen etc.
4. White water system:
Including white water tower, chest and trough etc.
5. Auto-control system:
Including spot instrument and control-room instrument controlled by
Being diluted by white water, the stock in the machine chest was
pumped into cleanings with the fine stock in the first stage pumped
into deaerator in which the air was separated from the stock by
hit, falling film and boiling etc and was discharged by vacuum
pump. The stock after being deaerated was pumped to pressure screen
by low pulse pump, then into the headbox. The system can meet all
the needs in pumping, cleaning, deaeration and screening of the
stock and provide stable stock consistency and pressure for the
headbox, and improve dewatering and formation of the sheet in wire
section and keep paper machine running well and get good paper
