At present, the ion exchange resin technology applied in industry is mainly the traditional three-tower fixed bed technology. The equipment has a large floor area, low resin utilization rate, and large consumption of resin, regeneration reagents and water. Continuous ion exchange technology is a completely innovative separation process technology. It is developed based on the traditional fixed-bed resin adsorption and ion exchange technology, combined with a continuous countercurrent system. Through continuous disengagement, the separation column can complete the entire process of adsorption, water washing, leaching, and regeneration in one process cycle.
The equipment has a compact structure, few pipelines, and a small footprint.
High resin utilization, can greatly reduce the amount of 50% -90%.
Product yield, concentration and purity are high and stable.
The consumption of washing water and chemical reagents is small, which can save 50% -70%.
The emissions of the three wastes are very small, reducing the pressure on environmental protection.
