01 Site Assessment & Foundation Construction:
Select level ground with ≥5t/m² bearing capacity, align with process flow requirements
Cast concrete foundation (C25 grade) with anchor bolts, verify horizontal error ≤3mm
Select level ground with ≥5t/m² bearing capacity, align with process flow requirements
Cast concrete foundation (C25 grade) with anchor bolts, verify horizontal error ≤3mm
Assemble steel frame with anti-corrosion bolts (M16), verticality tolerance ≤1‰ height
Install hopper with 3mm asbestos sealing rope at flange joints
Insert PTFE filter bags gently into tube sheet holes, secure with spring tension rings
Maintain 5mm gap between filter bags and cages to prevent abrasion
Mount air tank (1.5× design pressure tested) and align nozzles (±2mm to bag centers)
Label pulse valves (0.5-0.7MPa operating range) for maintenance traceability
Connect inlet/outlet ducts with 3mm rubber gaskets, bolt tightening torque ≥45N·m
Conduct smoke leakage test (≤2% leakage rate) at welds and access doors
Wire PLC cabinet (IP54 rated) with differential pressure sensors (0-2500Pa range)
Verify grounding resistance ≤4Ω and motor phase sequence
Activate pulse cycles (15-30s intervals) and monitor fan bearing temperature (≤80°C)
Adjust damper openings to maintain 800-1500Pa system pressure drop
Issue inspection certificate (GB 16297-2025 compliance) with ≥99.5% efficiency data
Submit as-built drawings and O&M manuals with lubrication schedules
