The scrubber system is so compact that a full-scale unit can easily be shipped to a customer's site for field-testing. It is a completely skid-mounted unit, consisting of a quench tank (if required), and a dynamic/mechanical scrubber with motor, demister, control panel and associated instrumentation for system control. In addition, the net pressure rise provides the motive force needed to convey gases through the system, often eliminating the need for a separate induced draft fan. Stack gases containing heavy metal particulates, inorganic ash, acid gases and objectionable odors are adiabatically cooled in the system's optional quench tank. The gases then enter the dynamic/mechanical scrubber, a rotary device consisting of a liquid atomizing impeller housed in a unique enclosure that incorporates an advanced geometric design. Water is injected into the stack gases and the impeller blades impact and accelerate the gases and water droplets to create a dense aerosol of suspended water droplets. These droplets coat the particles, allowing them to be removed by the demister.
