In the era of rapid development in new energy and materials, maintaining clean production processes is critical. At LEFILTER, we are committed to sustainable practices and eco-friendly solutions. Here's a highlight of our recent project involving state-of-the-art dust collection systems in the integrated platinum-group metal material industry.

Project Overview

Our scope of work included full-process services for baghouse dust collector systems and supporting engineering for two catalyst workshops:

• Copper-based Catalyst Workshop (Workshop III)

• Palladium and Platinum Catalyst Workshop (Workshop I)

Services provided:
✅ Design
✅ Supply
✅ Installation
✅ Commissioning
✅ Technical Support

First Exhaust Gas Treatment Process

• Airflow: 3,000 m³/h

• Dust Concentration: 200 mg/m³

• Dust Composition: Copper-silicon mixture with 20% copper content, 1% moisture.

Process Flow:
1️⃣ Exhaust gases pass through a cyclone dust collector, reducing dust concentration to ≤100 mg/m³.
2️⃣ The treated gases are combined with three other exhaust streams before entering the 1# baghouse dust collector for final filtration and discharge via a chimney.

Second Exhaust Gas Treatment Process

• Airflow: 5,600 m³/h

• Dust Type: Nano-scale silicon dioxide particles.

Process Flow:
1️⃣ Dust-laden gases enter the 2# baghouse dust collector.
2️⃣ Gases pass through a fan and are treated in a scrubbing tower, leveraging the water-soluble nature of nano-SiO₂ for removal.
3️⃣ Treated gases are discharged via a chimney.

Scrubbing Tower Features:

• Material: FRP or 304 stainless steel.

• Internal Velocity: ≤1.5 m/s.

• Configuration: Two-layer packing, dual spray systems, maintenance platform, and dual-circuit pumps (one standby).

Third Exhaust Gas Treatment Process

• Airflow: 1,000 m³/h

• Dust Concentration: Up to 5 g/m³ (post-treatment standard: ≤10 mg/m³).

• Dust Composition: Copper-silicon mixture with 20% copper content, 1% moisture.

Equipment Features:

• Heavy-duty silent casters with brakes for mobility.

• Industrial-grade handle for easy movement.

Fourth and Fifth Exhaust Gas Treatment Processes

• Airflows:

• 8,800 m³/h → 3# Baghouse Dust Collector → Fan → Chimney

• 2,200 m³/h → 4# Baghouse Dust Collector → Fan → Chimney

• 5,500 m³/h → 5# Baghouse Dust Collector → Fan → Chimney

• 2,200 m³/h → 6# Baghouse Dust Collector → Fan → Chimney

Design Highlights:

• Online cleaning mechanisms for all dust collectors.

• Uniform specifications for filter bags and cages, ensuring easy replacement and interchangeability.

A Step Towards Sustainability

Aligned with the growing focus on sustainability, LEFILTER is dedicated to advancing green production technologies to support the “Dual Carbon” goal. By ensuring cleaner air and more efficient processes, we continue to contribute to the ecological and industrial development of the new materials sector.
