Reverse jet pulse cleaning is a widely adopted method for cleaning filters in industrial applications. Such filters can typically take the form of bag filters or pleated cartridges – the actual mechanisms for particle removal from the media being different in both cases and are strongly influenced by the pulse pressure that presents against the internal surface of the filter media. Current practice in industry can see the use of compressed air reservoirs operating up to 5 bar to deliver a compressed air pulse into the throat of filters (via one or more distribution pipes) – however, in many cases the pressure used in the system can be arbitrarily arrived at and may not be optimal (resulting in poor cleaning and/or wasted energy in the form of compressed air). This paper considers the output from a novel small scale air filter media test rig which indicates the potential for defining an optimal cleaning pressure using an accelerated test procedure.
