Product Description
White Liquor CD Filter: 


--- Applied to white liquor and lime mud separation in recaustisizing plant

--- Dual function of filtering emulsion and washing lime mud

--- Ideal substitute for WL clarifier, LM washer or WL pressure filter

Working Principle: 
Recaustisizing emulsion is pumped to WL Filter while compressed air is fed to the Filter, pressure difference of 100kPa forces white liquor to flow through precoat and fabric into sector inside and then to center shaft. Filtrate flows through distribution valve to filtrate tank in which air is separated from white liquor.

WL pumps to storage tank, air goes to compressor and partially back to the Filter after being pressurized. Partially compressed air is supplied to air agitator for long and short blowing.

Cake is discharged by scraper , and falls through chute into LM tank. LM Partially pumps to storage tank, partially recycled between LM tank and chute which will balance lime mud consistency and avoid jamming. 


--- Disc type, large filter area, high production rate, less footprint, compact structure;

--- Precoat technology: high clarity, reduce scaling of other equipment, cost reduction;

--- Cake scraping automatically: scrape is controlled depending on vat level.

--- Operation at positive pressure, prevent white liquor oxidation, heat los, filtered WL temperature remains  high;

--- Distribution valve: easy maintenance,
