Apparatus for removing sulfur dioxide and particulate matter from flue gases
An apparatus is described for the removal of sulfur dioxide and particulate matter from flue gases wherein a pump extracts hot flue gases from a furnace and discharges such gases, and the particulates entrained therein, into one end of an extractor comprising a horizontal series of water-containing extraction chambers. The gas under pressure is forced from one chamber to the next through communicating openings in the lower side walls of the chambers, the gas pressure being sufficient to displace some of the water and maintain at least the final chamber in substantially filled condition. The water in the series of extraction chambers combines with the sulfur dioxide in the circuitously-flowing flue gases to produce an acid solution, thereby extracting the sulfur dioxide and simultaneously washing particulates from the gases. A suitable heat exchanger is disposed in at least one of the chambers for transferring heat from the water to a fluid circulated through the exchanger.
