AI Technical Summary

Technical Problem

In existing cross-flow filtration equipment, larger particles or impurities can easily enter the ceramic membrane directly, causing membrane pore blockage, reducing filtration efficiency and shortening membrane lifespan. At the same time, it causes wear and tear on the conveying mechanism and ceramic membrane, affecting the purification effect.

Method used

A high-precision cross-flow filtration device was designed, including a filter cartridge and a buffer assembly. The filter screen initially intercepts larger particles, the buffer assembly reduces pressure impact and protects the ceramic membrane, a polylactic acid degreasing layer is used to improve the purification effect, and further filtration is performed through the ceramic membrane.

Benefits of technology

It improves filtration efficiency, extends membrane lifespan, protects the delivery mechanism and ceramic membrane, ensures purification effect, and enables the recycling of raw solution and cleaning of membrane surface.
