Project Overview
Full-process services for bag dust collector systems and supporting projects in Catalyst Workshop 3 (Copper-based Workshop) and Catalyst Workshop 1 (Palladium-based & Platinum-based Workshop) of the Platinum Group Metal Materials Integrated Industry Construction Project: covering design, supply, installation, commissioning, and technical services.
First Stream Exhaust Gas Treatment Process
Flow Rate: 3,000 m³/h
Average Dust Concentration: 200 mg/m³
Particle Size Requirement for Crushing: 16-30 mesh, with finer dust generated during crushing or tablet pressing.
Dust Composition: Copper-silica mixture (silicon dioxide/copper), with copper content about 20% and material moisture content ~1%.
Process flow:
Exhaust gas first passes through a cyclone dust collector, reducing dust concentration to ≤100 mg/m³.
Merges with three other streams of dusty gas and enters the subsequent No.1 bag filter.
Treated gas is discharged through a chimney.
Second Stream Exhaust Gas Treatment Process
Process flow:
Passes through No.2 bag filter.
Goes through a fan.
Enters an exhaust gas absorption water washing tower for final treatment.
Discharged via chimney.
Water Washing Tower Specifications:
Material: FRP or 304 stainless steel
Internal flow rate ≤1.5 m/s
Equipped with 2-layer packing and 2-layer spraying system
Includes maintenance platform, circulating pump (one in use, one standby), and pressure gauge at pump outlet.
Third Stream Exhaust Gas Treatment Process
Flow Rate: 1,000 m³/h
Maximum Dust Concentration: 5 g/m³ (discharge standard: 10 mg/m³)
Particle Size: 16-30 mesh (with finer particles during crushing/tableting)
Dust Composition: Copper-silica mixture (20% copper, ~1% moisture)
Equipment Features:
Fourth & Fifth Stream Exhaust Gas Treatment Process
Fourth Stream: 8,800 m³/h (No.3 fan)
Fifth Stream: Platinum-based 5,500 m³/h + Palladium-based 2,200 m³/h
Treatment flow:
No.4 bag filter → No.5 bag filter → No.4 fan → chimney
Palladium-based 2,200 m³/h → No.6 bag filter → No.5 fan → chimney
