A venturi, or gas-atomized spray, scrubber accelerates the gas stream to atomize the scrubbing
liquid and to improve gas-liquid contact. In a venturi scrubber, a "throat" section is built into the duct
that forces the gas stream to accelerate as the duct narrows and then expands. As the gas enters the
venturi throat, both gas velocity and turbulence increase. The scrubbing liquid is sprayed into the gas
stream before the gas encounters the venturi throat. The scrubbing liquid is then atomized into small
droplets by the turbulence in the throat and droplet-particle interaction is increased. After the throat
section in a venturi scrubber, the wetted PM and excess liquid droplets are separated from the gas
stream by cyclonic motion and/or a mist eliminator. Venturi scrubbers have the advantage of being
simple in design, easy to install, and with low-maintenance requirements. An example of a venturi
scrubber is provided in Figure
The performance of a venturi scrubber is dependent to some extent on the velocity of the gas
through the throat. Several venturi scrubbers have been designed to allow velocity control by varying
the width of the venturi throat. Because of the high interaction between the PM and droplets, venturi
scrubbers are capable of high collection efficiencies for small PM. Unfortunately, increasing the venturi scrubber efficiency requires increasing the pressure drop which, in turn, increases the energy
consumption.

ReplyDeleteIt is a request to share some more blogs like this as I was a little bit confused with the functions and performance of Wet Scrubber in Delhi but after reading this post I am now going to purchase this plant. Clear Ion Experts also has the answers to your unlimited queries.
