PGN & PGNX Concentration Filter

The Concentration Filter is an advanced integrated system designed for efficient chemical synthesis and particle processing applications. It seamlessly integrates with synthesis reactors to enhance reaction efficiency, achieve uniform particle size distribution (PSD), and optimize material morphology. This versatile solution supports sustainable manufacturing by minimizing waste and maximizing yield through precise control and automation.

Key advantages include:

  • Enhanced particle integrity for superior product quality
  • Improved co-precipitation efficiency
  • Reduced material loss during processing

With flexible material lining options for slurry-contact components and magnetic-impurity-free filtration, it ensures contamination-free operation. Fully automated features, such as grouped backflush, continuous cycling, and multi-point control, enable uninterrupted, high-throughput production.

Technical Features

Modular Design

Modular Design

Drive System

Drive System

Equipped with high-quality reducers (e.g., SEW or equivalents) and variable frequency drives for stepless speed control of the agitator, ensuring optimal mixing.

Agitation

Agitation and Flow Guidance

Custom paddle blades paired with a draft tube promote thorough mixing and turbulent flow, tailored to material properties and vessel volume for maximum reaction uniformity.

Sealing Options

Sealing Options

Fillers or dual mechanical seals to meet process requirements, preventing leaks in demanding environments.

pipeline reactor

Pipeline Reactor

High length-to-diameter ratio (>50) for intensive turbulent reactions; customizable with state-of-the-art domestic or international technologies.

Filtration and Automation

Filtration and Automation

Microporous tubes provide precise, non-magnetic filtration; integrated DCS supervisory system monitors and controls parameters like pH, flow rates (instantaneous and cumulative), and temperature via on-site, control room, and pump triple-linkage.

Process Performance

PGNX process 1

Reaction & Aging: Within the reactor, multi-parameter controls precisely regulate crystal nucleation and growth. Multi-stage agitation and an inverted microporous filtration layout enable fine crystals to continuously recirculate to the reaction zone. This prevents settlement and filter blockage, while promoting the formation of a narrow, consistent crystal size distribution.

Washing & Purification: High-purity water, hot water, or solvent is introduced through dedicated process lines. Thorough mixing ensures effective impurity removal, meeting stringent product purity specifications.

Concentration & Filtration: Integrated vacuum, precision microporous filtration, and automated control systems progressively concentrate the slurry to the target density. This design minimizes pressure load on the filtration unit, enhancing operational stability and lifespan.

Overall Efficiency: The system enables fully automated, continuous operation with minimal downtime. By ensuring tighter control over PSD (Particle Size Distribution) and morphology, it significantly increases product yield and quality, while reducing energy consumption and material waste.
