Continuous Displacement Injection Disc Filter for High-Efficiency Solid-Liquid Separation in Pulp Washing, Black Liquor Extraction, and Fiber Recovery Processes

Continuous Displacement Injection Disc Filter 
Design Principle:
The Continuous Displacement Injection (CDI) Disc operates on the principle of continuous displacement. Washing liquid is injected into the pulp, displacing black liquor and impurities through a continuous and highly efficient washing process.

Technical Features:

• High Displacement Efficiency:
  Ensures thorough contact between washing liquid and pulp, rapidly displacing dissolved impurities and minimizing chemical usage.
• Corrosion-Resistant Materials:
  Typically constructed from stainless steel or corrosion-resistant alloys to withstand the highly alkaline black liquor environment.
• Precision Manufacturing:
  Features a smooth surface and evenly distributed gaps for uniform pulp distribution and flow.

Application Requirements:
Suitable for washing processes involving medium-to-high consistency pulp.

Core Applications:

• Black liquor extraction, particularly in continuous washing stages of chemical pulping processes.
• Ideal for modern pulp production lines requiring high washing efficiency.
