"The biggest advantages of wet scrubbers are the maintenance is minimum, it can remove gaseous pollutants, can handle high moisture air streams and if you have explosive dust it's very easy to handle in wet scrubbers versus cyclone or pulse jet" - Jay Shah, VP Sales - Scrubbers
Whenever you have a project the obvious question in everybody's mind should be what is my best solution because many times you'll go ahead and think well this is the application where somebody used a cyclone so why don't we use a cyclone or somebody used a filter why don't we use filters or somebody used scrubbers why can't we use scrubbers
Before you get that far i think the important thing for everyone to look up is what your data are. Once you know your design data it will make more sense to select the correct equipment for your application. In other words you do not want to overspend or you do not want to use more horsepower or you do not want to use up a lot of maintenance cost. So I prepared this quick table as you can see
Cyclone works very well at smaller airflow, so your airflow is smaller it will be more efficient. Pulse Jet Filters work at any airflow, and it can remove any size of particles. Wet Scrubbers work at any airflow and that can also remove submicron particles
The biggest advantages of wet scrubbers are the maintenance is minimum, it can remove gaseous pollutants, can handle high moisture air streams and if you have explosive dust it's very easy to handle in wet scrubbers versus cyclone or pulse jet
Recently we have seen in the paper industry, where particles are explosive, they have started to use wet scrubbers more and more, and the reason behind that is pressure drop for that application based on their particle size distribution is about 12 to 14 inch.
The biggest advantage is no explosion venting and in many applications they have used the bleed rate back into their system.
