Study Notes
Mechanical Separations
- Applicable to heterogeneous mixtures, not homogeneous solutions
- Based on physical differences between particles, including:
- Size
- Shape
- Density
- Used to separate:
- Solids from gases
- Liquid drops from gases
- Solids from solids
- Solids from liquids
Gravity Settling Chamber
- Simplest type of dust collection equipment
- Consists of a chamber with reduced gas/fluid velocity to enable dust particles to settle out via gravity
- Key features:
- Large cross-sectional area compared to ducts
- Baffles used to spread incoming flow evenly across the settling chamber
- Importance of baffles:
- Prevents poor particle collection due to uneven flow
