Abstract
A twin tower gas drying system is disclosed for cleaning compressed air lines in locomotives, buses, transit vehicles and the like by removing undesirable contaminants from an air or gas stream. A multistage filtration process employs a first scrubber that is capable of removing particulate material or soot from a stream of unpurified gas. A pre-filtering means is employed to remove impurities from the stream of unpurified gas. Coalescing filters are us to remove remaining moisture from the gas stream. Two towers of dessicant material dry the gas stream. The drying system is capable of controlling the flow of gas by alternately switching between supplying unpurified gas to a first tower and supplying unpurified gas to a second tower, with a purge cycle in between. Thus, a first dessicant tower is being purged of moisture while the second tower accumulates moisture, and likewise the second tower is purged while the first tower accumulates moisture, in alternating sequence.
