AI Technical Summary
In the traditional process of preparing copper chloride dihydrate, the escaping steam carries away latent heat and entrains droplets, leading to pipe blockage and increased separation costs, and the water vapor separation is incomplete.
A multi-effect evaporation system is constructed by using a single-effect evaporator and a double-effect evaporator. Combined with the design of the stirring components and evaporation tubes, the evaporation rate and heat exchange efficiency are improved through dynamic fluid formation, intermittent steam exhaust and falling film flow. The system also utilizes a reflux insulation jacket to recover liquid droplets entrained in the steam.
It effectively reduces heat loss, improves evaporation rate and heat exchange efficiency, avoids steam entrainment of droplets, reduces separation costs, and achieves efficient preparation of copper chloride dihydrate.
