wet-impingement scrubber
Quick Summary
A wet-impingement scrubber is a type of air pollution control technology that removes suspended particles from a gas stream by direct contact with a liquid spray. In this process, the gas and liquid mixture collides with a solid surface, which atomizes the liquid into smaller droplets. This increases the total surface area for contact, allowing the scrubber to trap particulates more effectively.1
Wet-impingement scrubbers are advantageous because they can handle hot airstreams and sticky particles, making them suitable for industrial and chemical processing facilities, as well as hazardous-waste incinerators. They offer removal efficiencies of about 90 percent for particles larger than 2 micrometers.1
