Method for extraction and disposal of flammable and explosive dusts at processing machines in e.g. industry, involves delivering secondary ignition volume flow into process chamber for removal of dust

摘要

The method involves suctioning off volumetric air flow from a processing machine, and depositing particles by formation of a dust cake on a planar filter element in a process chamber (A). The dust cake is suctioned off by secondary volumetric air flow from the process chamber, and a detection element is provided with a detector e.g. thermal sensor, located on the filter element to prevent suction of ignition in the secondary volumetric air flow. Secondary ignition volume flow is delivered into another process chamber (B) for removal of dust. An independent claim is also included for a device for extraction and disposal of flammable and explosive dusts in a temporally and spatially separated device.
