Technical Analysis of Fluidization Plates (Fluidization Discs)
Fluidization plates (fluidization discs) are key components in dense-phase powder conveying systems, mainly used at the bottom of injection tanks or pulverized coal bins. They achieve efficient, long-distance conveying by uniformly mixing compressed air with powders (such as pulverized coal) to form a stable fluidized state. Below is a detailed description of their core design features and working principles:
- Material: Made of 1Cr18Ni9Ti stainless steel plate (thickness approx. 3mm), with excellent high-temperature resistance (up to 800℃), corrosion resistance (suitable for harsh environments such as chemical and metallurgical industries), and high mechanical strength.
- Pore Structure:
- Long Slits: Arranged in a cross-shaped layout, with slits perpendicular to the central cross line to ensure uniform air flow distribution.
- Slit Parameters:
- Gap: 0.5mm (controls air flow accuracy)
- Length: 20mm
- Pitch: 10mm (optimizes air flow penetration)
- Chamfering Treatment: The lower edge of the slits is chamfered at 1×45°, which concentrates compressed air in the middle, enhances the suspension and fluidization effect of pulverized coal, and improves conveying stability.
2. Core Functions and Advantages
- Efficient Fluidization: The precision-designed slit structure allows air flow to penetrate the powder layer uniformly, forming a stable solid-gas two-phase flow and avoiding local accumulation or blockage.
- Energy Saving and Consumption Reduction: Optimized air flow distribution reduces compressed air consumption and lowers operating costs.
- Strong Adaptability:
- Suitable for newly built injection systems or modification of existing systems.
- Can be designed as fixed welded type (for long-term stable working conditions) or movable type (bolted) (for easy maintenance and replacement).
3. Application Scenarios
- Blast Furnace Pulverized Coal Injection System: Ensures stable conveying of pulverized coal to the blast furnace and improves combustion efficiency.
- Pneumatic Ash Conveying System: Used for conveying fly ash in power plants and chemical plants.
- Other Powder Conveying: Such as dense-phase or dilute-phase conveying systems for cement, lime, mineral powder, etc.
4. Technical Optimization Directions
- Porosity Adjustment: Custom slit parameters can be designed according to different powder characteristics (particle size, density) to optimize fluidization effect.
- Wear-resistant Coating: For high-wear working conditions, a wear-resistant coating can be added to the stainless steel surface to extend service life.
