OPTIMAL CONDITION FOR FABRIC FILTER CLEANING WITH IMPULSE JET
Abstract
The research presents the experimental study on a created pulsejet cleaning bag intended for a fabric filter in order to compare its efficiency to a polyester filter and a linen filter. The tests were conducted by filling 20 kilograms of sawdust particles into the fabric filter which were washed using varying pressures ranging from 60-100 Psi and the pressure drops of the fabric filter at the inlet and outlet were measured and compared. The results of the experiment revealed that the cleaning efficiency of the pulsejet fabric filter with a polyester bag should apply at the pressure level of 70 Psi and the one with a linen bag should apply at the same pressure level (70 Psi). This impulse pressure was the result when the pressures dropped to minimums of 3.9 mmH2O (-0.415dB) and 5.35 mmH2O (-0.5659dB), respectively. It was also found that the cloth-type filter had cleaning efficiency as the pulsejet type with no significant difference (p-value>0.05). Overall results concluded that the pulsejet performed effectively and was suitable for industrial use.
