Case study: Extended Filter Life and Reduced Annual Operational Costs Solved – Using Cleaning Venturi and EFS design for Glass Filtration Media Application
Process
One of the largest manufacturers of glass filtration media approached EF Specialists to improve their dust extraction systems. Used glass cullet is processed to develop the filtration media, as a result this application can create large volumes of dust due to the abrasive nature of the glass.
Substance Type: Organics and crushed glass dust (amorphous silica dioxide)
Problems / Issues
- Replacing filter cartridges on 3 x dust collectors every 6-8 months
- Environmental impact due to filter cartridges leaking when blinded
- Limited performance of dust extraction systems due to high differential pressure
- Higher energy consumption
- Tight pleat distance on each filter cartridge
- Restricted surface cake discharge on the filter cartridges
- Poor cleaning performance of the filter cartridges
Images of situation before EF Spsecialist improvements :
Solutions / Improvements
- EF Specialists design of JET filter with improved pleat technology
- Enhanced surface cake discharge, improved surface finish and strengthened steel spiro mesh
- Install newly bespoke design of cleaning venturi for more efficient cleaning
- Regular planned maintenance visits for spot checks
Images of results after EF Specialists improvements :
Results
- Current filter cartridges perform at a more consistent lower pressure drop
- Lower energy consumption due to being able to reduce the fan speeds
- Filter life extended between 12-18 months
- Less operational down time between filter changes as there is no emission
- No excessive dust present within the surrounding areas
- Lower air pressure required for cleaning due to the venturi
