- Dust Precipitators
- Removes harmful particles from factories that pollute the atmosphere.
- 1. Metal grid placed in chimney, given large charge.
- 2. Plates inside chimney- earthed, gain opposite charge to grid.
- 3. Dust particles pass close to grid = become charged with same charge as grid.
- 4. Dust particles repelled away from wires. Attracted to oppositely charged plates and stick to them.
- 5. Plates are vibrated and dust falls down to a collector.
- 6. Dust particles gain or lose electrons to become charged.
- 7. Charge on dust particles induces a charge on earthed metal plate.
- 8. Opposite charges attract so dust is attracted to plate.
