Working principles advantages disadvantages and limitation of venturi scrubber?

Answer 1

A Venturi scrubber is a wet scrubber that essentially washes gases or particulates out of a gas stream.

To accomplish this removal it is necessary to mix the "dirty" gas with fine droplets of the fluid used to remove them. A Venturi accomplishes this by passing the washing fluid through a tapered neck in the Venturi nozzle introducing the gas and liquid into the system . The high speed gas breaks the fluid into tiny droplets and mixes them with itself. The fluid picks up the impurities and coalesces into larger droplets which either fall out of the gas or are collected on impingement plates or packing. The purified gas leaves the system, the dirty fluid is sent for disposal or purified for reuse.

Answer 2

Venturi scrubbers work by using high-velocity water or liquid to generate a fine mist that traps particulate matter, which is then collected. One advantage is their high collection efficiency for fine particles. However, they can be expensive to operate due to high water and energy consumption. Additionally, they are not as effective for removing gases or odors.
