制袋工艺及密封方式对滤袋过滤性能的影响

为满足各地日益严苛的排放标准要求,滤袋制袋工艺及密封方式尤为重要.对三针缝制工艺(不做密封处理)、三针缝制后针孔涂胶密封工艺及热熔密封工艺制备的滤袋进行荧光粉渗透性能和过滤性能研究,结果表明:无论是荧光粉渗透测试还是动态除尘过滤试验,三针缝制后针孔涂胶密封工艺和热熔密封工艺制成的滤袋均能阻隔粉尘渗透,且过滤效率相对较高.其中,三针缝制后针孔涂胶密封工艺制备的滤袋,过滤面积损失小,透气性适宜,过滤效果最佳.
Effect of making process and sealing method on filtration performance of filter bags
In order to meet the increasingly stringent emission standards,the bag-making process and sealing methods are particularly important. The phosphor permeation and filtration properties of filter bags prepared by three-needle sewing process (without sealing treatment),pinhole glue sealing process after three-needle sewing and hot melt sealing process were studied. The results showed that the filter bags prepared by pinhole glue sealing process after three-needle sewing and hot melt sealing process could block dust permeation and the filtration efficiency was relatively higher,no matter they were phosphor permeation test or dynamic dust removal filtration test. Among them,the filter bag prepared by pinhole glue sealing process after three-needle sewing had the best filtration effect with small filtration area loss and suitable air permeability.
