ABSTRACT:
A sulphur dioxide converter and pollution arrester system which involves the treatment of smoke and/or contaminated air emanating from a combustion area by passage through a zone achieving turbulence into a water spray contained first treating chamber. The turbulence zone, into which an atomized catalyst is introduced, serves to create a longer path for cooling as well as increased centrifugal motion to the solid particles in the contaminated air and also the formation of sulphur trioxide. In other words, the arrangement is such that pollution arresting action is provided in the form of "slinging" resulting from tangential directional movement and, when combining with the water spray in the first treating chamber, the ultimate formation of sulphuric acid.
Subsequently, the contaminated air, containing amounts of sulphurous and sulphuric acids, passes through a second treating chamber, where airflow throughout the system is occasioned by action at the outlet end, such as the vacuum created by a flue and not by independent mechanical means. The arrangement serves to a two-fold purpose, i.e. to minimize or arrest pollution and to convert sulphur dioxide, a component of high sulphur coal, into commercially valuable sulphuric acid.
