ABSTRACT:
A pollution control system comprises method and apparatus for removing particulate and gaseous pollutants from combustion products. The method includes a series of physical and chemical treatments for combustion products. In one embodiment these steps are: passing combustion products through a screen to filter out large particles; washing combustion products with steam; passing combustion products through activated carbon; washing combustion products with a solution of potassium aluminum sulfate, aluminum sulfate, aluminum hydroxide, chlorine, and quicklime; washing combustion products with an aqueous solution of kerosene and naphthalene; and washing combustion products with a solution of aluminum hydroxide, aluminum sulfate, chlorine, quicklime, and sodium carbonate. The apparatus, which is adaptable to a combustion unit, comprises a boiler for steam generation; a mixing chamber for steam and combustion products adjacent the combustion unit and steam boiler; a filter between the mixing chamber and a filtration chamber, with the filtration chamber adaptable to contain activated carbon; a series of three combustion products washing members, each adaptable to wash combustion products with wash fluid, and each including means to circulate wash fluid and remove any solid matter from the wash fluid.
