Industrial Venturi Wet Scrubber uses the differential between high velocity gases and free-flowing water to create droplets which entrap contaminants, hold them in suspension and deliver them as highly concentrated slurry. The Wet Scrubber offers more advantages in separating and recovering liquid mists and ultra-fine particulate than other gas cleaning methods. The Wet Scrubber incorporates features calculated to maximize collection efficiency while minimizing operating and maintenance costs. The Industrial Venturi Wet Scrubber employs non-plugging, trouble-free method of introducing scrubbing liquid and a simple, easily-adjusted throat for optimizing efficiency.
