AI Technical Summary
Existing cyclohexanone dimer production equipment suffers from waste of cyclohexanone and water resources during wastewater treatment, resulting in low utilization rates of raw materials and resources.
By setting up a combination of material conveying system, condenser, water distributor, evaporator and cooling tower, high-temperature steam condensation, multiple evaporation and cooling of wastewater are achieved, and cyclohexanone raw material and water resources in wastewater are recycled.
It improves the recovery rate of cyclohexanone in wastewater and the overall resource utilization rate, reduces raw material waste, and enhances production efficiency and safety.
