The reverse pulse jet baghouse has been around for over 45 years and the cleaning cycle has not changed very much since that time. The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In a generic baghouse, the cleaning system is comprised of a blowpipe that is located typically approximately three inches above the bag, with an orifice and a venturi, which is located at the top of the bag/cage. This system uses bursts of compressed air at 100psi and back flushes one row of filters at a time during the cleaning cycle. This cleaning system has some deficiencies and thus Scientific Dust Collectors (SDC) introduced a special converging/diverging nozzle based cleaning system in 1981. SDC eliminated the venturi and provided a unique and patented cleaning system, which significantly improved filter life and lowered pressure drop. Over these many years, SDC’s technology has been field proven in a wide variety of applications. Scientific Dust Collectors is now proud to introduce the “Next Generation of Nozzle Technology”. By improving the nozzle design SDC has achieved an even better filter cleaning system.
