Improving the Effectiveness of Filter Regeneration by Pulse Scavenging

Resumo

Scientific research and experimental-design work are performed to improve the effectiveness of regenerating bag and cassette filters by reverse pulse scavenging. It is recommended that the velocity and flow rate of the compressed air used for scavenging be chosen as the regime parameters, depending on the physico-mechanical properties of the dust that is being captured. A method of calculating the grouped distribution of collectors is proposed to uniformly distribute the compressed air among the scavenging nozzles. It is also recommended that swirl nozzles be used to equalize the pressure pulses along the filter elements.
