Principle of Operation
The Jet Venturi scrubber is similar to an Ejector or Eductor. That is, it has a spray nozzle which creates a high velocity of one fluid, typically water. In the Fume scrubber, the second connection on the Venturi is for gas. The gas can be air with dust or fumes. It can be process flow such as fuel gas in a synthetic fuel plant.
The wet scrubber will handle dirty gas streams by mixing water or water solutions with the air or gas and transferring the solids or soluble gases to water.
Gases are often neutralized, but not necessarily. For example, Hydrochloric acid can be converted over to Sodium Chloride, “table salt”. Particles can be captured and separated out of the water phase.
Scrubbers are especially suitable for applications involving high levels of gases, simultaneous gas, solid removal, and corrosive services.
