The submerged jet scrubber (photo) is an advanced development of the jet scrubber, combining the separation of particles with physical and chemical absorption. It consists of a wash pipe with or without wall rinsing, a specially designed gas distribution, a flow tube and a liquid feed tank. To increase the efficiency, the submerged jet scrubber can be provided with additional scrubber nozzles for dust separation and absorption. All components are designed to be modular, easy to install and allow fast and easy maintenance. For applications in the field of hot gas, a special quench can be added to the individual components so that the unit is converted to a submerged jet quench. The advantage of the submerged jet scrubbers in comparison to jet or Venturi scrubbers is their wide range of applications at significantly lower investment and operating costs. Exhaust or fluegas can be reliably cleaned, even under varying operating conditions. — GEA Wiegand GmbH, Ettlingen, Germany
