Abstract:

The VMoTi/glass-fiber catalytic filter-cloth (VGCF) with denitrification (DeNOx) and dust removal (Dedust) function was prepared by impregnation method, and NOx and dust removal performance of VGCF was systematically studied. The effects of catalyst-loading, binder, reaction temperature, filtering velocity, SO2 and H2O on the performance of DeNOxand Dedust were investigated, combined with SEM, XRD and EDS characterization methods. It was found that the DeNOx efficiency is 60%—85% at 200—250℃ when the loading capacity was 130 g/m2 and the filtering velocity was 0.5 m/min. Further, after 500 times of pulsing aging, the DeNOx efficiency is basically unchanged, indicating good stability of DeNOx. After adding SO2 and H2O, the DeNOx efficiency is maintained at more than 75%, showing great resistance to SO2 and H2O. The dust removal efficiency of VMoTi/glass fiber composite catalytic filter cloth is above 99.99%, which meets the requirements of actual industrial smoke and dust treatment applications.

摘要:

采用浸渍法制备出具有脱硝除尘功能的VMoTi/玻纤复合催化滤布,研究了VMoTi/玻纤复合催化滤布的脱硝除尘性能。考察了负载量、黏结剂、反应温度、过滤风速、SO2和H2O对脱硝除尘性能的影响,通过SEM、XRD及EDS表征手段进行分析,结果表明:当负载量为130 g/m2,过滤风速为0.5 m/min,在200~250℃下,脱硝效率为60%~85%。且在定压喷吹老化500次后,脱硝效率无明显下降,表现出良好的脱硝性能稳定性。通入SO2和H2O后,脱硝效率维持在75%以上,具有良好的抗水硫性能。VMoTi/玻纤复合催化滤布除尘效率在99.99%以上,满足实际工业烟尘治理应用要求。
