Description

一种复合过滤布
技术领域
本发明涉及过滤布技术领域，尤其是一种用于工业除尘设备的一种复合过滤布。
背景技术
目前，现有工业除尘器使用的过滤布一般有长丝和短纤纱制成的过滤布，或者是由单丝和长丝织成的过滤布。前者由于硬度小、强度低，在除尘设备的喷吹除尘过程中容易损坏，使用寿命较短。后者的过滤布在除尘器的较大风压下单丝和长丝易滑移，造成过滤布的局部孔径增大，从而影响到过滤除尘效果。
发明内容
鉴于上述问题，有必要提供一种能应对的技术方案。
本发明提供一种复合过滤布，粉尘抖动坠落效果较好、使用寿命长，过滤除尘效果较好。
本发明的技术方案是：
一种复合过滤布，包括基布和过滤布，所述基布是由单丝、复丝或纱线通过纺织而成的经纬交织结构；所述过滤布是由若干经线和纬线针刺成型的无纺布结构，所述基布和过滤布通过粘合或针刺连接复合为一体，所述过滤布的表面设有若干圆形、锥形、椭圆形或矩形结构的凸体。
作为本发明的进一步优化或改进，所述基布为由氯纶、 聚酯纤维或涤纶制成的布料，所述基布厚度为0.5mm-0.7mm。
作为本发明的进一步优化或改进，所述过滤布为由玻璃纤维、丙纶长丝或玄武岩纤维制成的布料，所述滤布厚度为0.3mm-0.5mm。
作为本发明的进一步优化或改进，所述凸体的高度为 0.35mm-3.0mm。
作为本发明的进一步优化或改进，所述过滤布的表面进行轧光或烧结处理，使其表面光滑、平整、坚固。
本发明具有以下有益效果：
本发明提供一种复合过滤布，本发明过滤布的表面设有若干凸体，即使在高速过滤、高含尘浓度的条件下工作，也能保持较好的集尘效果，同时粉尘的抖落效果良好，并且滤袋的过滤布不易堵塞，适用于各类工业除尘器，不仅有利于降低滤袋的破损率，延长滤袋的使用寿命，而且能够降低工业除尘器的能耗，提高除尘效果。
