Wet scrubber – alkaline gases, fine dust, heavy metal vapors, and some water-soluble VOCs simultaneously in a single device.
Shenzhen Xicheng (Xicheng) focuses on R&D and manufacturing of exhaust gas treatment systems and engineering plastic equipment. We provide one-stop solutions—from site survey, process design, installation & commissioning to operation & maintenance—for factories in the chemical, electroplating, food, textile & dyeing, and heavy industries.
Unlike single-function dedicated equipment (fabric filters only remove dust, activated carbon mainly adsorbs organics), Xicheng’s wet scrubber can simultaneously treat solid, liquid, and gas phase pollutants in one device, tackling the most complex exhaust gas challenges.
Wet scrubber: A Multi-Functional, Flexible Solution
The wet scrubber uses liquid (water, alkaline/acid solutions, oxidants, etc.) to absorb, neutralize, and wash away multiple pollutants:
-
✅ Solid phase: Fine dust, ultrafine dust (including PM2.5), sticky dust, flammable/explosive dust
-
✅ Acidic gas phase: HCl, SO₂, H₂S, HF, NOₓ, Cl₂, CrO₃ …
-
✅ Alkaline gas phase: NH₃, amines …
-
✅ Heavy metal vapors: Hg, Pb, Cd, Cr …
-
✅ VOCs (partial): Acetone, ethanol, formaldehyde …
Eight Outstanding Advantages of Xicheng’s Wet Scrubbing Technology
✅ 1. Versatile – One unit replaces multiple processes
| Pollutant Type | Traditional Equipment | Xicheng Wet Scrubber |
|---|---|---|
| Dust | Bag filter / Cyclone | ✅ Direct treatment |
| Acidic gases | Separate absorption tower | ✅ Direct treatment |
| Alkaline gases | Separate unit | ✅ Direct treatment |
| Heavy metal vapors | Expensive filter media | ✅ Direct treatment |
| Water-soluble VOCs | Activated carbon | ✅ Partial absorption |
Benefit: Saves space, reduces equipment investment, simplifies operation.
✅ 2. Handles “Difficult” Conditions – High temperature, high humidity, flammable/explosive
| Challenging Condition | Capability of Wet Scrubber |
|---|---|
| High temperature (200-400°C) | Direct treatment, cooling by water evaporation, no pre-cooling needed |
| High humidity, dust that condenses | No clogging; unlike fabric filters, no “bag blinding” |
| Flammable/explosive dust (Al, Mg, coal) | Water environment eliminates ignition sources – completely safe |
| Sticky, oily, or hygroscopic dust | Washed away completely, no adhesion to equipment |
✅ 3. Integrated Cooling, Humidification & Gas Conditioning
-
Rapid cooling: Reduces exhaust temperature to below 80°C within a short distance.
-
Humidification: Provides required humidity for downstream biological treatment or wet processes.
-
Neutralization of corrosive gases: Converts HCl, SO₂ into neutral salts, protecting chimneys and fans.
✅ 4. Very High Removal Efficiency Across a Wide Particle Size Range
| Parameter | Efficiency |
|---|---|
| Dust >1µm | ≥ 99% |
| Dust 0.3-1µm | ≥ 95% |
| PM2.5 (Venturi design) | ≥ 90% |
| Acidic gases (HCl, SO₂) | 95 – 99% (depending on liquid-to-gas ratio) |
✅ 5. Safe, Reliable, No Secondary Dust
-
No secondary dust: Dust is trapped in water and discharged as sludge.
-
Few moving parts: Spray tower has no complex internal mechanisms – fewer failure points.
-
Adapts to load fluctuations: When flow or concentration changes, simply adjust spray rate or chemical dosage – still meets emission standards.
✅ 6. Compact Design, Modular, Easy to Integrate
-
One wet scrubber replaces cyclone + bag filter + absorption tower – saves 50-70% floor space.
-
Can be designed as vertical, horizontal, or skid-mounted – easy to transport and install.
✅ 7. Recovers Valuable By-Products
| Inlet Gas | Recovered Product | Application |
|---|---|---|
| H₂S | Sulfur | Chemical raw material |
| SO₂ | Gypsum (CaSO₄) | Gypsum board production |
| HCl | Regenerated hydrochloric acid | Reused in electroplating, etc. |
✅ 8. Insensitive to Inlet Dust Concentration
| Equipment Type | Recommended Max Inlet Dust Concentration |
|---|---|
| Bag filter | <50 g/m³ (higher accelerates bag wear) |
| Xicheng Wet Scrubber | >100 g/m³ (only need to increase sludge discharge frequency) |
Especially suitable for high‑dust‑load industries: coal‑fired boilers, mineral crushing, cement kilns, etc.
Industry Applications
| Industry | Typical Application |
|---|---|
| Chemicals & Fertilizers | Treat HCl, SO₂, NH₃, fertilizer dust |
| Electroplating, Battery Manufacturing | Absorb acid mist, Cr⁶⁺, lead, mercury |
| Boilers, Waste Incineration | SO₂ removal, NOₓ reduction, cooling, coal dust removal |
| Metallurgy, Aluminum Casting | Treat high‑temperature flue gas, metal dust, HF |
| Food Processing | Odor removal (H₂S, NH₃), treat oil mist |
| Painting, Printing, Dyeing | Remove solvents, acid mist, pigment dust |
