SPARK ARRESTOR BOXES

Much of our work at Filter Designs operates on processes such as aluminium and glass furnaces, pyrolysis plants and waste to energy systems. High temperatures of up to 1200° C mixed with impurities in the process and/or process variables can lead to sparks exiting the process into our gas treatment plant.

Typically, cyclones are used pre-filter when a high dust loading is anticipated. However, our filter (see CleanPulse) has an inlet distribution section making it suitable for high dust loading without the need for a cyclone.

Furthermore, cyclones offer little impact surface and no physical barrier for foreign materials, such as a rag, piece of plastic film or other foreign body.

cleanSPARK

Our cleanSPARK arrestor boxes reduce the risk of fire in the bag filter by knocking out material which is alight in the airstream before they can enter the dust collection unit.

The process air is directed by the inlet ducting downwards and impinged on plates to encourage the spark to be extinguished. The secondary chamber then has perforated sheets to capture any larger items which could be alight.

Each spark box will be different in size due to the overall gas volume.

Filter Designs use CFD modelling to optimise flow, pressure losses and particulate flight path.

Our recent Projects

We were contracted to provide 2 small Ceramic filters suitable for a small volume but with a design maximum temperature of 600°C. In addition the filters will be handling a syngas which cannot be mixed with oxygen so an alternative to compressed air would need to be used for the ‘Cleanpulse’ cleaning of the 25 Ceramic element in each of these CPC78 filters. In addition dosing of small amounts of a re-agent is required so the client also opted for a ‘Cleandose’ 25kg bag skid. Find out more about Project CAD below.
