Most of the evaporators (reboilers) used in the petrochemical industry, pharmaceutical and water treatment plants adopt conventional evaporators (reboilers) with the disadvantage of low heat exchange efficiency and relatively high energy consumption. Compared with conventional equipment, WCE’s high-efficiency falling film evaporator (reboiler) can potentially reduce energy consumption by over 30%.
The Falling Film Evaporator features a large concentration ratio, wide viscosity range, very low to negligible pressure drop, excellent heat transfer coefficient, large treatment capacity etc. It is widely used in the petrochemical plants for production of glycol, ethanolamine, caprolactam, styrene, alkylphenol, acrylic fiber, polyester, chlor alkali, polycarbonate, and water treatment as well as in the light and food industry.
（1）Combined hydraulic design and structure optimisation of the liquid distribution device in the channel/the film distributor at the tube end opening.
（2）Guided flow forming model for the hydrodynamic calculation for the new film distributor at the tube end opening.
（3）Achieve design selection and optimisation of the falling film evaporator is achieved by our in-house developed non-dimensionalised correlations of the minimum liquid falling film forming flow.
（4）The enhanced heat transfer calculation model of fluted heat exchanger tubes.
（5）The thermal process calculation software and structure design technology of the new type efficient falling film evaporation equipment.
The coordinated design technology of the structure optimization and hydraulic calculation of the liquid distribution device in the tube box and the film distributor at the mouth of the heat exchanger is formed. The forming technology and the enhanced heat-transfer calculation model of longitudinal groove heat exchange tube is developed. And the thermal process calculation software and structure design technology of the new type high efficiency falling film evaporation equipment is developed.
