Pulse-jet cleaning performance of sintered filter cartridge dust collector
To examine the dust cleaning performance of a sintered filter cartridge,the peak value of the side wall pressure of the sintered filter cartridge was measured on a self-constructed clean pulse-jet blowing test platform.The resistance of the dust collector during operation and the amount of dust after dust removal were observed in additional experiments,which led to the identification of the optimal combination of dust removal parameters.The results indicated the optimal parameters for ash removal were as follows:the injection pressure was 0.3 MPa,the injection diameter was 10 mm,and the injection height was 160 mm.The peak lateral pressure values at the three measuring points on the upper,middle,and lower parts of the sintered filter cartridge were 5 032,5 230,and 5 877 Pa,respectively.Under the optimal cleaning parameters for lithium iron phosphate powder,when the dust concentration was 50 g·m-3,increasing the filtration wind speed from 0.6 m·min-1 to 1.4 m·min-1 results in an increase in the stable operation resistance of the system and a decrease in cleaning efficiency.The dust concentration increased from 25 g·m-3 to 100 g·m-3,and as a result,cleaning efficiency decreased.As the D50 size of dust particles increased,the cleaning efficiency improved.The experimental results can provide engineering guidance for the industrial application and widespread use of sintered filter cartridge dust collectors.
