Raille spark detection systems prevent fires and explosions in dust extraction filters and in material handling conveyors.
Any process which involves putting energy into flammable material has an inherent risk. Ignition sources can be generated by friction, tramp metal or worn machinery and are carried through the dust extraction ducts to the filter and through the conveyors to storage silos. The machinery, conveyors and dust extraction plant are generally enclosed and a fire, once ignited, may be difficult to access and extinguish.
Spark detectors react to infra red light from ignition sources being carried through the dust extraction ducts or conveyors. Sparks, embers, hot particles and burning material are all detected and activate a high-speed extinguishing reaction immediately downstream. The extinguisher generates a curtain of water in the path of the spark, before it reaches that point. This barrier prevents the spark from reaching the filter.
For an isolated spark, only a brief extinguishing spray is required and there is no need to shut-down extraction or interrupt production. Upon detection of a continuous stream of burning material, the control system would activate an automatic shut-down of the plant and release additional extinguishing systems into the machine where the fire originated.
Raille provides a complete system design, installation and commissioning service, together with on-going spare parts and maintenance support for spark detection systems.
