在以江、河、湖、海为水源的地区,原水中往往夹带着水生动物,如饰贝、藻类等。在取水过程中,随着水流进入管道和构筑物后便附着在管壁上繁殖聚积。从而缩小管道过水断面、增加水头损失,降低输水能力。如进入设备,则影响正常生产,甚至酿成严重的设备事故。 为了截滤水中的机械杂质和水生动植物,通常是在进水管道上安装过滤器,但经多年生产,实践证明,老式过滤器存在以下难以克服的缺点: In areas where rivers, rivers, lakes and seas are sources of water, raw water is often encrusted with aquatic animals such as shellfish and algae. In the process of water intake, as the water enters the pipelines and structures, it will accumulate on the wall and accumulate. In order to reduce the pipeline cross-section, increase head loss and reduce water delivery capacity. If you enter the equipment, it will affect normal production and even cause serious equipment accidents. In order to cut off the mechanical impurities and aquatic plants in the water, filters are usually installed on the inlet pipe. However, after many years of production, practice has proved that the old filter has the following insurmountable disadvantages:
