What are the types of fluidizers?

Tank Fluidizer Main Types of Fluidization Devices
Fluidizers and fluidization devices can be categorized into the following types based on structure, function, and application scenarios:
1. Structural Classification
Single Fluidization Device
Circular Fluidized Bed: Suitable for vertical tanks, with two types of porous plates—conical plates (cone angle 120°–150°) and flat circular plates. Conical plates are ideal for bottom discharge, while large cone angles (>150°) are suitable for top discharge.
Square/Rectangular Fluidized Bed: Square types are used for multi-bin tanks, and rectangular types for horizontal inclined tanks.
Y-Shaped Fluidized Bed: Specifically designed for horizontal tanks.
Composite Fluidization Device
Combines multiple single devices (e.g., rectangular + circular), integrating both fluidization and conveying functions, commonly used in horizontal drum-shaped tanks.

2. Functional Classification
Silo Fluidizer: Installed at the lower part of the hopper, it introduces air through porous plates to fluidize powdered materials and prevent bridging.
Vibrating Fluidized Bed: Combines vibration and airflow, suitable for materials prone to caking.
Pulsed Fluidized Bed: Enhances fluidization effects through periodic airflow pulses.

3. Application Scenario Classification
Drying Fluidized Bed: Such as single/multi-layer cylindrical fluidized beds, used for drying materials like polytetrafluoroethylene.
Reaction Fluidized Bed: Such as catalytic cracking fluidized beds, which facilitate gas-solid reactions through gas distribution plates.
Biological Fluidized Bed: Includes liquid-fluidized beds (two-phase), gas-fluidized beds (three-phase), and mechanically agitated fluidized beds.
4. Special Types
Inert Particle Fluidized Bed: Uses inert particles as carriers for processing high-viscosity materials.
