Impingement Tray Scrubbers, Type W60

Our Impingement Tray Scrubbers are a cost effective solution for control of particulate matter, acid gases and for flue gas cooling downstream of incinerators and waste heat boilers.  The W60 scrubber provides efficient particulate capture with low energy requirements.  It is easily adapted to new or retrofit installations and, as with many of our scrubbers, is capable of particulate capture down to 1 micron in size.  The Impingement Tray Scrubber accommodates changing gas flow automatically and is designed to provide highly efficient gas absorption.

Liquid is introduced at the top tray and completely covers the tray surface.  An adjustable weir ensures coverage on the tray.  The liquid rate is determined by the process requirements and the tray design.  A downcomer arrangement allows the liquid to cascade down from the top tray to the lower trays.

As gases pass up through each flooded tray stage, particulate matter in the flue gas impinges on the liquid droplets formed on the top surfaces of each tray and is washed down to the lower section.

The liquid droplets formed on the tray surface also provide tremendous surface area for contact with acid gases and/or flue gas cooling.  If the scrubbing liquid is recycled, caustic or another suitable alkali is normally used to control pH of the liquid.

The benefits of an Emtrol Impingement Tray Scrubber are:

	low pressure drop/low liquid requirements
	vertical or horizontal gas outlet
	low maintenance
	corrosion resistant construction

Emtrol's expertise in scrubbing technology, corrosion resistant materials and system design has proven valuable in many applications. Our Project Brief entitled Particulate and SO₂ Emissions Control describes actual employment of the Impingement Tray Scrubber.
