AI Technical Summary

Technical Problem

In existing titanium dioxide industrial wastewater settling equipment, the particle sorting effect brought about by swirling is difficult to effectively translate into actual separation efficiency. Ultrafine particles are re-rolled up by the water flow in the channel and carried back to the clear water zone, resulting in poor solid-liquid separation effect.

Method used

A sedimentation device comprising a cyclone separation zone and a diversion sedimentation zone was designed. A continuous spiral flow channel along the wall is formed by spiral guide grooves and spiral guide ribs to achieve radial separation and stable sedimentation of particles. Combined with honeycomb inclined tube packing, deep sedimentation is achieved. The combined action of centrifugal force and gravity is used to prevent particles from being retained or rolled up in the channel.

Benefits of technology

It achieves efficient solid-liquid separation, improves the classification and sedimentation effect of large and ultrafine particles, reduces equipment energy consumption, and enhances the stability and separation efficiency of the sedimentation process.
