A venturi scrubber collects particles chiefly by

  • A.Atomising liquid so particles impact droplets
  • B.Allowing particles to settle in a spray chamber
  • C.Charging the particles electrically
  • D.Filtering the gas through a wetted fabric

Answer: A

The high relative velocity between gas and injected liquid shatters the liquid into fine droplets and drives particles into them. It is the most effective wet device for fine particulate and correspondingly the most demanding in pressure drop.
