采用氧化铝多孔材料进行减压蒸馏海水淡化实验,分别研究了海水的入口温度、流量以及蒸馏单元内的真空度对减压蒸馏量的影响。结果表明,随着入口温度的增加,减压蒸馏量呈抛物线增长的趋势,但不是无限增长的;减压蒸馏量随着蒸馏单元内真空度的增加而呈线性增加,但是增加趋势没有温度对减压蒸馏量的影响大;减压蒸馏量随着海水流量的增加而增加,但当流量超过40L/h时,减压蒸馏量几乎没有变化。
Adopting alumina porous material for desalination desalination seawater desalination experiments, the effects of seawater inlet temperature, flow rate and the degree of vacuum in the distillation unit on the amount of vacuum distillation were studied. The results showed that the vacuum distillation showed a parabolic trend with the increase of the inlet temperature, but it did not increase indefinitely. The vacuum distillation showed a linear increase with the increase of the vacuum in the distillation unit, but the increasing tendency did not have the temperature The effect of vacuum distillation is large. The amount of vacuum distillation increases with the increase of seawater flow rate. However, when the flow rate exceeds 40 L / h, the amount of vacuum distillation changes little.
