Centrifugal Spark arrestors for dust collection
Review
Description
Centrifugal Spark arrestors for dust collection Detail：
• Feature：
The spark arrestor (or spark arrester) is a device that prevents the emission of Flammable sparkle dust from combustion sources into the dust collector whose filters are bags, polyester cartridges, or sinter-plated filters. The small spark posed a super hazard to dust explosion or fire disaster.
Centrifugal spark arrestors make up with stationary vanes to trap down high gravity sparks or particles by centrifugal force. In other words, Centrifugal forces throw the sparks against the wall of the arrestor, where they are separated then pull through filters.
The exhaust spark arrester sometimes is considered as a horizontal cyclone for powder separation or recycles especially for the high gravity dust. Some customer uses this spark trapper as a pre-collection for high-density dust. Further more, some dust with oils is also can be trapped to protect the terminal equipment (attention: please consider the duct safety in explosive atmosphere).
• WHAT IT DOES：
• Cools and arrests sparks without water or chemical injection
• Reduces burn-damage to filter media
• Reduces duct and dust collector damage
• Destratifies temperature and cools local hot spots
•SPARK MITIGATION：The Spark Cooler is ideally suited to mitigate sparks generated in metal and other low-load material processing applications, under non-explosive conditions. The Spark Cooler works to create turbulence in the air flow stream, thereby disturbing the thermal bubble surrounding the spark and allowing the lower temperature in the gas stream to influence the particle temperature. It is not an extinguishing system and should never be applied as a standalone device in processes requiring absolute spark suppression.
• Application：
Extinguishes and cools sparks / burning embers from welding fumes, plasma cutting table, grinding, polishing, buffing, belt sanders, furnaces, biomass boilers, and any application which creates a possible spark hazard.Robotic welding of oily stamped products; Robotic and automatic welding of oily products;Manual welding of oily products.
Position: lazar cutting machine.
Dusts contain: oils, cutting fume, spark, carbon, and carbon steel…
Function: spark trap before into the dust collector.
Working feedback: without this equipment, the bag house burned before, after use it, no risk of fire hazards.
