Description

A multi-stage membrane filtration separation device

Technical Field

The utility model relates to the technical field of filtering equipment, in particular to a multi-stage membrane filtering and separation equipment.

Background Art

With the promotion and popularization of drinking water and health knowledge, people have gradually understood the impact of drinking water quality on human health and paid more attention to drinking water safety. For this reason, water purification devices that can effectively remove floating objects, heavy metals, bacteria and viruses in water have been loved by more and more people. However, there are many types of water purification devices on the market, with complex structures, cumbersome filter element cleaning and replacement, and incomplete filtration. Similar products on the market use PP cotton + reverse osmosis + activated carbon as the main process. PP cotton can intercept large particles of impurities, but the impurities remain on the PP cotton in the form of adsorption. If it is not replaced for a long time, the PP cotton will cause secondary pollution to the raw water.

At present, the traditional multi-stage membrane filtration system has a complex structure and requires multiple connecting pipes to connect to achieve multi-stage filtration, which is costly. In addition, the traditional multi-stage membrane filtration system needs to replace the multi-stage membranes one by one, resulting in low replacement efficiency.
