For a less demanding, lower throughput gas cleaning system, the venturi scrubber is a well tested and respected design used by many industrial processes.

It uses a combination of vortex technology and high pressure water misting to remove harmful elements from the exhaust gases.

How does a Venturi Scrubber work?

The overall process is quite straight forward - the key to successful operation is ensuring there is a continual flow of air and water made available to the venturi scrubber. As the gas stream is introduced into a scrubber box, it is forced to pass through a converging section, where (in accordance with Bernoulli equation) gas stream velocity is rapidly increased. The throat section between pipes is where particle and gas removal occur as the inlet gas stream mixes with the fog of tiny liquid droplets.

• Entering the diverging section, the gas stream is forced to slow down.
• Scrubbing liquid is introduced into a system using a high pressure pump (70+ bar) and a set of 8 micronic nozzles.
• Energy from the gas stream is used to additionally atomize water droplets.
• Part of the scrubber liquid that doesn’t evaporate in the process is released from the system using specially designed valve on the bottom of the scrubber box.
