Sulphur dioxide converter and pollution arrester system

A sulphur dioxide converter and pollution arresting system comprising a source of smoke containing sulphur dioxide, ductwork directing the movement of said smoke into a first treating chamber, said ductwork including a turbulence creating zone, means introducing a catalyst into said ductwork, said first treating chamber having a series of outlets therein passing atomized liquid directly downwardly by gravity through the path of movement of said smoke, a deflector disposed within said first treating zone serving solid and liquid separating purposes, a second treating chamber communicating with said first treating chamber, said second treating chamber positioning a series of depending conduits for passage of said smoke and including a volume of liquid at the bottom thereof into which said series of conduits extend and into which said smoke is introduced, an outlet duct directly communicating with said second treating chamber at the top thereof and above the level of said liquid and arranged to permit liquid entrained in smoke passing from said second treating chamber to return by gravity flow into said second treating chamber, and a flue communicating with said outlet duct achieving the vacuum flow of said smoke through said system, said sulphur dioxide in said smoke combining with said catalyst and said liquid in said first and said second treating chamber to produce sulphuric acid.
