 The use of wet scrubbers for control of air pollution has gained wide acceptance throughout industry in the last six decades. And for good reason. The ejector-venturi wet scrubber provides a number of advantages over many of the conventional single-purpose devices available. Particulate collectors such as cyclones and electrostatic precipitators cannot efficiently absorb gases or remove odors. Fabric filters, by design. cannot cope with gas streams having a high moisture content and are often affected by highly corrosive gases- Catalytic incinerators can be quickly poisoned by certain organic wastes.
On the other hand, ejector-venturi gas scrubbers are very effective at removing noxious gases. particulates, odors. fumes and dusts from gas streams. Particulate contaminants are removed through impaction by the high velocity spray of scrubbing liquid. Gases and odors are eliminated through absorption and/or chemical reaction between the gases and scrubbing liquid. When properly matched to the application, these scrubbers, by their nature, are better able to cope with the high temperatures and corrosive conditions often encountered.
Northeast Controls offers over sixty years of experience in the control of commercial and industrial air pollution using wet scrubber technology. The ejector-venturi gas scrubbers described on the following pages have been engineered to operate effectively in a variety of applications. Using the same basic design, these standard scrubbers can be sized to meet volume requirements from a few CFM to thousands of CFM. This broad applicability permits us to stock these Scrubbers in a wide range of sizes and materials. A stock ejectorventuri scrubber can often be the most economical and efficient solution to a pollution control problem. |
