When selecting the type of evaporator or designing the evaporator, on the premise of meeting the requirements of production tasks and ensuring product quality, it is also necessary to take into account the simple structure, easy manufacture, convenient operation and maintenance, good heat transfer effect and so on. In addition, it is also necessary to have good adaptability to the process characteristics of the material to be evaporated,rotovap distillation, including the viscosity, heat sensitivity, corrosiveness of the material and whether it crystallizes or scales.
The climbing film evaporator is suitable for evaporating low-boiling point alcohols or low-boiling point volatile organic compounds; The falling-film evaporator is suitable for the concentration of water-soluble substances and the evaporation of materials which are not easy to crystallize or scab; The horizontal falling film evaporator is suitable for the evaporation of volatile organic compounds with medium boiling points such as ethanol; The natural internal circulation evaporator is suitable for the concentration and evaporation of general materials; The forced external circulation evaporator is suitable for the evaporation and crystallization of high-concentration and easy-to-crystallize materials; The combination of falling film and forced external circulation evaporator is suitable for the concentration and crystallization of low-concentration and easy-to-crystallize materials; The combination of natural circulation and forced external circulation evaporator is suitable for the crystallization of the thickener of the medium and low concentration materials which are easy to crystallize; The combination of forced external circulation and multi-effect evaporation crystallization is suitable for secondary concentrated crystallization containing high-boiling inorganic or organic substances; Selection Criteria for Common Evaporation Equipment Return to Sohu to see more Responsible Editor:. toptiontech.com
