Fluidizer for bottom silo (sulfurization unit)

Below are the installation and operation specifications for the tank bottom silo fluidizer (fluidization device).
Installation Requirements
The cone surface must be polished smooth, the flange fully welded and tested for airtightness, and tilted at 30° to cover dead spots.
Layout Density: 3-5 fluidization points per square meter of the cone surface.
Operation Optimization
Use pulsed air supply (air on for 2 seconds/off for 10 seconds), saving over 30% energy.
Air Source Requirements: Dry compressed air/nitrogen (dew point ≤ -40°C).
Maintenance Points
Replace the fluidization plate every 12 months, and inspect seals every 6 months.
Cleaning Method: Compressed air back-blowing (0.4MPa), water washing is strictly prohibited.

I. Manufacturer and Procurement Reference
Model‌ ‌Specifications‌ ‌Unit Price‌ ‌Manufacturer‌
DN400 Bottom Discharge Type 316L Stainless Steel ¥2000 Lanhao Environmental Protection
DN1000 Top Discharge Type 304 Stainless Steel + Ceramic Lining Inquire for Price Jinglan Environmental Protection
DN860 Fluidization Plate Thickness 20mm, Outer Diameter 860mm Detailed Inquiry Xiangye Environmental Protection
Selection Recommendations:
For high-pressure systems (>1.6MPa), choose custom models with thickened shells;
For high-sulfur coal powder scenarios, prioritize 316L material.

II. Safety and Efficiency Verification
Operational Safety
Before maintenance, empty the tank and depressurize; configure explosion-proof solenoid valves for nitrogen environments.
Performance Testing
After commissioning, residual coal powder in the cone should be ≤0.3kg/m²;
Fluidization gas consumption standard: 0.3-0.6Nm³/kg of coal powder.
Application Value: The tank bottom fluidizer can improve coal powder silo emptying efficiency by over 40% and reduce equipment failure rates by 30%-40%.
