All-effect evaporating conocentration process

The present invention is all-effect solution evaporating concentration process. The technological process is completed in an all-effect solution evaporating concentration apparatus with the typical structure comprising one evaporating pot, three heat exchangers and several regulating valves. During the process, afterheat and secondary vapor are utilized fully, and only small amount of outer supplied energy is consumed in the continuous efficient solution evaporating concentration. 一种对溶液的全效蒸发、浓缩工艺，用于对溶液节能、高效的蒸发、浓缩。该工艺使用典型构造为由一个蒸发罐和三个换热器及多个调节阀门组成的全效蒸发浓缩装置，实行对余热和二次蒸汽充分利用，仅需要消耗少量的外部能量就能够对溶液连续、高效的蒸发、浓缩。
