Basic Introduction to Fluidized Disc
Below is a comparative analysis between the fluidized disc (multi-layer sintered metal wire mesh fluidized plate) and traditional metal woven wire mesh, highlighting its core differences and performance advantages:
;1. Structural Design Comparison Features Traditional Metal Woven Wire Mesh Fluidized Disc (Sintered Multi-layer Wire Mesh) Structural Form Simple single-layer or multi-layer stacking Multi-layer wire mesh precision lamination + high-temperature sintering composite Pore Morphology Mesh holes are prone to deformation with irregular shapes Fixed cross-shaped gaps (e.g., 0.5mm gap × 20mm length) Edge Treatment No special treatment Chamfer design (1×45°) to optimize airflow guidance Integrity Easy layer shifting with poor integrity Integrated sintering with firm interlayer bonding
The fluidized plate is made of multi-layer metal woven wire mesh as raw material, prepared through processes such as special lamination design, composite pressing, and vacuum (or protective atmosphere) sintering. It can not only maintain the characteristics of simple pore structure and uniform mesh size of ordinary metal woven wire mesh, but also overcome its shortcomings such as low strength, poor integrity, and unstable mesh shape. Moreover, it can flexibly and reasonably match and design the pore size, permeability and mechanical strength of the material, so it has excellent comprehensive characteristics.
3. Application Effect Differences Fluidization Uniformity: Traditional wire mesh: Pulverized coal is prone to local accumulation with insufficient fluidization. Fluidized disc: Cross-shaped gap layout + chamfer design → airflow concentration → uniform pulverized coal suspension (injection stability ↑30%). Maintenance Cost: Traditional wire mesh: Difficult to clean after clogging with high replacement frequency. Fluidized disc: Smooth channels + no blind holes → convenient backwashing regeneration (service life extended by 2-3 times). Extreme Working Condition Adaptability: Traditional wire mesh: Prone to oxidation and embrittlement at high temperatures, and easy to fail in corrosive environments. Fluidized disc: Sintered layer enhanced thermal shock resistance + Ti element corrosion resistance (suitable for gasifier environments above 800℃).
