  • Improving the cleaning cycle in baghouse collectors

    ABSTRACT: Background 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 ...

  • Ineffective cleaning in generic baghouses

    ABSTRACT: Background In a typical “generic” baghouse application, the cleaning is accomplished by back-flushing the filter with compressed air that travels through an orifice hole in a purge tube (blow pipe) and through a venturi. A typical generic cleaning system allows dust to be filtered at an air-to-cloth ratio of 5:1. That means for every 5 CFM of airflow, there is 1 square foot ...

  • Advantages of cleaning without a venturi in baghouse collectors

    ABSTRACT: Background The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In order to clean a row of bags in a reverse pulse jet baghouse first the flow of filtered air must be momentarily stopped and then back flushed or “induce” air to knock the dust cake off the outside of the filter media. A venturi at the top of the ...

  • Improve performance by installing a larger filter bag

    YOU MIGHT NOT NEED a more powerful dust collector after all. That’s the word from woodworkers who’ve replaced the original equipment filterbags on their collectors with bags that are more efficient. You might ask, “What can be more efficient than the 1 micron bag that came with my collector?” The answer is a 1 micron bag that’s properly sized for your machine and ...

  • Pilot and Industrial-Scale Experimental Investigation of Numerically Optimized Cyclones

    A new geometry of reverse-flow gas cyclones obtained by numerical optimization was shown at the laboratory scale to be significantly more efficient than other high-efficiency designs. However, it is usually recognized that experimental results obtained with laboratory-scale or sampling cyclones cannot be extrapolated to pilot or industrial scales. The present paper confirms, at these larger ...
