How to breathe new life into your old pulse-jet dust collector
If replacing your aged, overburdened pulse-jet baghouse or cartridge dust collector isn't in the plant budget this year, why not consider resuscitating the unit instead? This article explains how you can breathe new life into an old pulse-jet dust collector by stepping up maintenance, optimizing the collector fan's performance, and switching to high-performance filter media. (Much of the information also applies to collectors other than pulse-jet units.)
Most pulse-jet dust collectors -- whether they use bag or cartridge filters -- don't break down and die. Sometimes the collector suffers from poor maintenance, mainly because workers don't want to deal with what most of them consider one of the dirtiest maintenance jobs in the plant. But the pulse-jet collector has very few moving parts; other than the dust discharge device, the only thing moving in this collector is air. While its parts may corrode or erode, the collector won't simply wear out. Over time, however, the collector can become overtaxed as the process gradually changes and the dust collection system expands to include more production equipment.
