Particulate Emission Control In Powder Spray Booth

Surface Engineering Association 2025 air pollution report shows 44% coating non-compliance comes from particulate over-limit. Deqing Leixin shares spray booth dust emission control methods.

H2: Industry Background & Main Challenges

• Fine powder escapes through booth gap

• Filter aging reduces dust capture efficiency

• Improper negative pressure leads floating powder emission

• H2: Particulate Control Solution

• Cyclone + cartridge filter dual-stage dust recovery

• Seal all booth gaps to prevent powder leakage

• Pressure difference monitoring to judge filter status

• H2: Dust Control Operation Steps

1. Seal spray booth wall and workpiece inlet/outlet gaps

2. Use two-stage recovery for coarse and fine powder

3. Replace filter cartridge once pressure difference exceeds threshold

H2: Practical Client Result

Hardware coating plant cut particulate emission below 8mg/m³.

FAQ

Q: What is typical particulate limit for coating exhaust?A: Common requirement ≤10mg/m³ for most regions.

Q: Single cartridge filter enough for fine powder capture?A: Cyclone pre-separation + filter is better for heavy production.
