Industrial processes generate significant dust and particulate matter—from cement kilns and power plants to steel mills, chemical reactors, and food processing facilities. Uncontrolled dust emissions harm worker health, damage equipment, violate environmental regulations, and contribute to regional air pollution. We provide complete, validated dust control solutions meeting EPA, EU Industrial Emissions Directive, China GB, and global standards.
Industrial dust varies widely in composition, particle size, concentration, temperature, and moisture content. No single technology fits all applications. Our systems integrate multiple complementary dust collection technologies into a compact, energy-efficient package tailored to your specific process conditions
Standard configuration (moderate dust, ambient temperature):
Process exhaust → Pre-filter → Baghouse / Cartridge collector → HEPA (optional) → Fan → Stack
High-temperature configuration (kilns, furnaces, dryers):
Process exhaust → Cyclone (pre-separator) → Fabric filter (high-temperature bags) → Heat exchanger (optional) → Fan → Stack
Explosive / combustible dust configuration (grain, wood, chemicals):
Process exhaust → Spark arrestor → Dust collector (explosion venting) → Isolation valve → Fan → Stack
Most common industrial dust collector. Dust-laden air passes through woven or felted fabric bags (fiberglass, polyester, aramid, PTFE). Dust cakes on the surface; cleaned by pulse jet, reverse air, or mechanical shaking. Efficiency: 99.5–99.9% for particles >0.5 µm. Air-to-cloth ratio: 0.8–1.5 m³/min•m².
Higher efficiency than baghouses in a smaller footprint. Pleated cellulose or synthetic media. Efficiency: 99.9%+ for particles >0.3 µm. Preferred for fine dust (welding fume, pharmaceutical, food). Air-to-cloth ratio: 0.6–1.2 m³/min•m².
Pre-separator for coarse dust. Centrifugal force separates particles >5–10 µm. Efficiency: 70–90% for 10 µm, <20% for 1 µm. Low pressure drop (0.5–1.5 kPa). Reduces load on downstream collectors.
For sticky, hygroscopic, or explosive dust. Dust contacts water spray, packed bed, or venturi throat. Efficiency: 90–99% for particles >1 µm, venturi can reach 0.5 µm. Provides simultaneous gas cooling and absorption. Produces wastewater requiring treatment.
For very high volume, high-temperature applications (up to 400°C). Charged corona wires ionize particles; collection plates attract dust. Efficiency: 99.5–99.9% for particles >0.1 µm. High capital cost, low operating cost. Used in power plants, cement, and steel.
For ultra-fine dust (pharmaceutical, cleanroom, nuclear). HEPA: 99.97% at 0.3 µm. ULPA: 99.999% at 0.12 µm. High pressure drop (0.5–1.5 kPa). Requires upstream pre-filtration.
Pollutant | Raw Emission | After Treatment | Efficiency |
Total particulate matter (PM) | 50–5,000+ mg/m³ | <10 mg/m³ (typical), <1 mg/m³ (HEPA) | 99%+ |
PM10 (≤10 µm) | 20–2,000 mg/m³ | <5 mg/m³ | 99%+ |
PM2.5 (≤2.5 µm) | 5–500 mg/m³ | <1 mg/m³ | 99%+ |
Visible opacity | >20% | <5% (clear stack) | N/A |
Industry | Typical Dust | Technology Selection | Key Requirement |
Cement / Lime | Clinker dust, lime | Baghouse or ESP | High temperature (200°C+), high loading |
Steel / Foundry | Iron oxide, slag fume | Cartridge collector + HEPA | Fine fume (<0.5 µm), high efficiency |
Power (coal) | Fly ash | ESP or baghouse | Very high volume, continuous operation |
Chemical / Pharmaceutical | API, excipient powders | Cartridge + HEPA (containment) | Zero leakage, safe change-out |
Food / Grain | Flour, grain dust, sugar | Cyclone + baghouse | Explosion venting, food-grade construction |
Woodworking | Sawdust, wood flour | Cyclone + cartridge | Spark arrestor, explosion venting |
Welding / Plasma cutting | Metal fume (Fe, Cr, Ni) | Cartridge collector (nanofiber) | Fine fume (<0.1 µm), source capture |
Asphalt / Concrete | Mineral dust | Baghouse | High loading, outdoor installation |
Pharmaceutical (tableting) | Active ingredient dust | Downflow booth + HEPA | Containment (<1 µg/m³ operator exposure) |
Battery manufacturing | Electrode powder (Li, Co, Ni) | HEPA + carbon pre-filter | Toxic dust, strict workplace limits |
