一种高粘稠度液体中带电杂质的过滤装置
本专利技术属于液体过滤设备领域,特别是一种高粘稠度液体中带电杂质的过滤装置。
技术介绍
根据某些粘稠度较大胶体溶液中,需要过滤分离的胶体粒子由于自身吸附性而带有一定的正/负电荷。因此,在对这些液体中的固体微粒进行分离时,可以采用传统过滤和通电共同作用的方式,使杂质能够均匀分布在滤网上,防止滤网上的滤渣分布不均影响滤网的使用效率。现有技术中,例如专利号为“201720128532.2”的专利“一种导流式环保型电化学除垢系统”中,采用多层水平网状电极滤层和水平旋转刮垢刀,通过控制系统检测水垢厚度,由人工操作电气系统进行除垢。该装置的含垢水从下方进入,从上方流出,清洗时清洗水从上方流入从下方流出,从而将水垢冲最下方的排垢口排出。由于部分溶液粘稠度很大,在向上方通过滤层过滤时具有很大粘滞阻力,导致滤层附近的流速非常缓慢,不仅降低了过滤效率,还使该装置需要越来越大功率的泵使液体循环流动,消耗大量电力。因此,该装置难以通过简单应用于高粘稠度液体的过滤中。
