  • 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 ...

  • 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 ...

  • 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 ...

  • Baghouse dust collector helps improve casting process one step at a time case study

    Cascade Dafo, Fernadale, Wash., designs and manufac- tures dynamic ankle and foot orthoses (orthotic braces) to help im- prove the mobility of children and adults with neuromuscular chal- lenges. In the past, the company used a cartridge dust collector to collect dust generated during the finishing step of a manual plaster-casting process. When the company auto- mated the casting process, it ...

  • How to Avoid Undersizing a Dust Collection System

    Baghouse manufacturers often recommend undersized systems to undercut others for your business. How can you avoid buying a undersized baghouse that won't work?  Dust collector OEMs constantly try to come in with bids lower than competitors. In an attempt to do so, some baghouse manufacturers offer undersized systems. One recent experince highlights the dangers of allowing manufacturers' ...

  • Vacuuming Wood Dust Can be Hazardous

    It’s well known that wood dust is highly combustible, but the practice of removing it with vacuum trucks can also be dangerous, because of the potential buildup of static electricity. WorkSafeBC has issued a bulletin stating that “static electricity discharges can ignite wood dust and therefore must be eliminated or adequately controlled during vacuuming.” When wood dust or ...

  • Horween Leather: Whirl / Wet Dust Collector Combines a High Efficiency Wet Dust Collection with Low Maintenance and Operating Costs.

    For leather fines and other lightweight, porous materials, dry collection has been thought to be preferable to wet because of the material’s buoyancy. Horween Leather Company challenged that assumption. Originally, two baghouse systems collected particulate, but problems arose with each baghouse. First, cold winter dryness caused high levels of static electricity. Resultant sparks in the ducts ...

  • Reduction in Airborne Dust and Cleaning Costs: Sale of Waste Limestone Dust - Blue Circle Southern Cement, Limestone Mine

    Background The Marulan South limestone mine is part of the Blue Circle Southern Cement company. It is situated on the edge of the Shoalhaven River gorge adjoining the Morton National Park 380 km south west of Sydney. The company supplies limestone to cement plants at Berrima and Maldon as well as the BHP steelworks at Port Kembla. The mine has a total production of three ...


  • Controlling Dust and Bioaerosols at a Biosolids Composting Faclity

    Studies at enclosed Longmont, Colorado project evaluate exposure level of employees. Operational changes reduce dust, endotoxin and A. Fumigatus by 90 percent. WHEN dealing with public health issues and composting, attention has been predominantly focused on potential exposure from the release of Aspergillus fumigatus (A. fumigatus) from composting facilities. Numerous studies were conducted to ...


  • Whirl/Wet Dust Collectors Preferred for Pharmaceutical Overspray Collection

    A major multi-national manufacturer of pharmaceuticals and vaccines chose Whirl Wet technology for a new pill coating operation. The aqueous-based sugar solution created heavy loadings of sticky overspray in the 3 micron range. This blinded the existing baghouses after just six batches despite the use of PTFE cartridges – (the best available option for baghouses used in this type of application.) ...

  • Dust Controlled at Source by TurboSonic Dry Fog® Suppression System

    When silica, limestone, cement, aggregate and other respirable dust particles ranging in diameter from 0.1 to 70 microns are airborne, they create a safety and health concern and an aesthetic nuisance. As a source of physical discomfort, lost materials and wear on conveying pulleys, idlers, belting and motors, such dust is a significant factor in lowered productivity and added operating and ...


  • To prevent blinding in dust collection systems, consider filter type, filter size and selection of the filter media used

    All dust collection systems, regardless of size, share a common problem—dust blinding. Simply stated, blinding is defined as when dust particles plug the holes in a filter and stop the flow of air through the filter, resulting in the dust collector performing poorly. All types of collectors, whether stand-alone units, cyclones or full-scale baghouses, are subject to blinding. To better ...

  • Minicipal Waste Incinerator Case History

    Low temperature plant operation had resulted in severe baghouse corrosion and constant dust blockages throughout the system. It was decided to raise the operational temperature of the incinerator and change the acid gas scrubbing agent from lime to sodium bicarbonate. However, the existing felt filter media could not cope with the change in acid gas scrubbing agent and “blinded” very rapidly ...

  • New Nozzle Technology “Cleaning More with Less”

    This technical paper will explain the new nozzle technology developed by Scientific Dust Collectors that allows high air-to-cloth ratio baghouses to use 80psig of compressed air instead of the industry standard 100psig.   The reverse pulse jet baghouse has been around for over 50 years and the cleaning cycle has not changed very much during that time. The cleaning cycle is the most important ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...
