Principle of Operation
The collecting tubes are arranged into a system of ponds whereby each tube is continuously flushed with water, the surface tension creating a complete ring and wall of water down the tube.
Particulate laden gases enter the base of the module and pass upwards through the steel tubes. The particulate is charged with negative ions from the influence of the HV discharge system and is attracted to the walls of the pipe. The particle is immediately carried away by the wall of water and carried out through the base of the module.
The HV system is periodically flushed by the spray system. Each module is isolated in turn for washing of the HV system.
