[Case Study] Indoor Installation of Dust Explosion Pressure Relief Type Dust Collectors

Introducing a case study that achieved indoor installation with explosion-proof bends and rupture disks!

There was a challenge of wanting to install a dust collector for explosive dust indoors, and issues with the explosion vent included flames escaping outside the unit during an explosion. As a countermeasure for when the dust collector is stopped, a "rupture disk" was adopted, and for flame protection during an explosion, an "explosion suppression vent" was implemented. As a result, by suppressing the release of flames through heat absorption and collision when passing through the suppression vent, the blast wave and temperature rise were mitigated, reducing damage to the surrounding area. 【Case Study】 <Problems with the explosion vent> ■ Flames escape outside the unit along with the blast wave during an explosion. ■ When the dust collector is stopped and the filter is cleaned, the vent cover may open, leading to the possibility of dust leakage. ■ The vent type is installed outdoors due to explosion risk. <Benefits> ■ Prevention of dust dispersion from the vent during stoppage. ■ Mitigation and reduction of blast waves and fires for the vent type. *For more details, please refer to the PDF document or feel free to contact us.

Explosion Suppression Vent "FlameQuench II"

A second-generation explosion suppression vent that achieves an explosion discharge without flames.

"FlameQuench II" is a model that significantly improves upon the challenges of the first-generation explosion suppression vent "FlamQuench." It was examined that the reduction in explosion dispersion effectiveness due to pressure loss from the suppression device was significant, but 80% of the explosion dispersion into the atmosphere is maintained. Since a dispersion duct is no longer necessary, it achieves indoor explosion dispersion with only minimal reduction in explosion dispersion effectiveness. Additionally, to prevent secondary explosions caused by the release of unburned dust, it has a structure that does not release dust particles larger than 60 microns. 【Features】 ■ Combination of explosion vent and suppression device ■ No flames are released during explosion dispersion ■ Maintains 80% of explosion dispersion into the atmosphere ■ Explosion vent and gasket must be ordered separately ■ Dispersion duct is no longer needed ■ Structure that does not release dust particles larger than 60 microns *For more details, please download the PDF or feel free to contact us.
