AI Technical Summary

Technical Problem

The existing multi-stage mixing and clarifiers have a small adjustable range of process parameters and low maintenance efficiency, resulting in low production efficiency.

Method used

The system employs a multi-stage series mixing and clarification tank, with each stage including an independent mixing chamber and a clarification chamber. The organic phase submerged chamber, aqueous phase submerged chamber, and reflux phase submerged chamber within the mixing chamber are isolated from each other. The material is reversed and refluxed through an overflow pipe. Combined with real-time monitoring and flow control, the system enables flexible adjustment of process parameters and independent maintenance.

Benefits of technology

It improved production efficiency, expanded the adjustable range of process parameters, shortened maintenance time, ensured the continuity and stability of production, and reduced equipment complexity and operating costs.

Abstract

本发明提供了一种混合澄清方法及混合澄清器,包括混合澄清方法和混合澄清器。混合澄清器包括多级串联的混合澄清槽;每级混合澄清槽均具有混合室和澄清室;混合室包括相互隔离的有机相潜室、水相潜室和回流相潜室,以及分别与有机相潜室、水相潜室和回流相潜室连通的搅拌室;澄清室与搅拌室连通本发明提供的混合澄清方法及混合澄清器,通过独立的进料管线和控制逻辑,使得任意一级可以作为独立的处理单元被切除或旁路,无需排空整槽液体,大幅缩短了检修时间。通过回流,未饱和的有机相被强制再次与水相接触,提高了单级萃取效率,从而在总级数不变的情况下获得更高的回收率,或在达到相同回收率时减少总级数,通过监测交换比来反馈控制流量。
