| Zusammenfassung: | The utility model provides a liquid caustic soda evaporation and concentration system. High-temperature and high-pressure live steam supplied by a steam pipeline is used as an initial heat source to evaporate and concentrate liquid caustic soda in a third evaporator; steam generated after the liquid caustic soda in the third evaporator is concentrated serves as a heat source in the second evaporator, and the liquid caustic soda in the second evaporator is evaporated and concentrated; steam generated after the liquid caustic soda in the second evaporator is concentrated is used as a heat source in the first evaporator to evaporate and concentrate the liquid caustic soda in the first evaporator; the low-concentration caustic soda liquid output by the caustic soda liquid pipeline sequentially passes through the first evaporator, the second evaporator and the third evaporator to be subjected to heat exchange and concentration step by step, and finally the high-concentration caustic soda liquid with the concentrat |
