Scrubbers

A low energy wet scrubber is a simple, yet extremely versatile air pollution control device that limits gaseous emissions by creating contact between exhaust gases and injected water.

The process is ingeniously simple … but very effective.

As they pass through the scrubber unit hot flue gases are rapidly cooled by atomized water that is forcibly injected under pressure through one or more spray nozzles.

Any dust particles (particulates) within the gas stream are instantly and effectively captured within the water droplets, after which they are deposited in the scrubber re-circulation reservoir. In addition to particulates this process also arrests heavy metals and to a large extent, acids in the form of sulfur and chlorine.

Where even higher levels of cleaning efficiencies are demanded, this can be achieved by augmenting the scrubber with venturi, nozzles and sodium hydroxide neutralization of the scrubber water.

Although this type of scrubber is a non-complex construction, it provides an internationally approved process for the efficient cleansing of incinerator flue gases.
