ABSTRACT:
The apparatus and method described herein comprises a sequence and arrangement of equipment and the method of operation thereof for the removal of water soluble pollutants and particulate matter from flue gases, such as those emanating from incinerators, furnaces, electric power generating stacks, etc. The apparatus comprises a prequench chamber leading the exhaust gas from a stack into a spray chamber operating under a negative pressure of 3 to 4 inches of water as induced by a fan or pump at the exit end of the spray chamber with the said fan inducing a positive pressure of 3 to 4 inches of water into the conduit leading the gases from the spray chamber to a cyclone separator in which most of the water entrained in the gas at that point together with wetted particulate matter is removed, following which the gas is fed to the bottom of a partially packed tower whereby impinging contact of the gas with the packing removes final traces of particulate matter, and then the gas is passed into a demister in which the gas impinges on a series of plates or surfaces arranged at various angles for removal of final traces of water droplets. The gas exiting from the demister is passed into a fan or pump which gives the gas at the exit of the pump a positive pressure of 6-8 inches of water to force the gas through a venturi which feeds into a stack partially open at the bottom to allow for suction of air into admixture with the exit gas thereby further cooling the gas and simultaneously dehumidifying the gas so that it exits from the top of the stack as an invisible, clean gas.
