Abstract
本实用新型属于气体过滤装置技术领域,具体涉及一种与湿式过滤器联用的后置过滤筒,包括竖向的外筒体,外筒体内设有与之同轴设置的内筒体,内筒体底端开口,其内装有滤棉;内筒体外壁设有多圈挡水环,挡水环外缘与外筒体内壁之间留设间隙;外筒体顶端设有与滤棉填充腔连通的出气通道,外筒体底端设有排水口。本实用新型先利用挡水环改变气体流向,使气体中的水汽(小液滴)与挡水片和筒壁碰撞而凝结并滴落,实现初步除水;再经过滤棉填充腔内的滤棉进一步吸附和过滤气体中的水分;最后通过出气通道下端的多孔滤材及其内的吸水填料,更进一步吸附和过滤气体中的水分。多级过滤层层递进,有效提升了气体过滤效果,保障了空气呼吸器的供气质量。
