MIST ELIMINATION/AIR TOXIC CONTROL IN A WET SCRUBBER USING A CONDENSING HEAT EXCHANGER

摘要

A system for eliminating mist from a flue gas while providing air toxic control includes a wet scrubber housing having an inlet at one of the housing for the entry of the flue gas and an outlet at an opposite end of the housing for the exit of the flue gas. Sprayers are located in the housing for spraying the flue gas with a cleaning liquid in order to remove contaminants from the flue gas. At least one heat exchanger is located in the housing above the sprayers in order to remove entrained contaminants from the flue gas by cooling the flue gas. The flue gas is channeled from the inlet past the collection trays, sprayers and heat exchanger prior to exiting the housing through the outlet. A mist eliminator is also provided for eliminating mist from the flue gas.
