蒸发器中结垢速率研究
THE RATE OF LIQUOR SIDE FOULING IN EVAPORATORS
【摘要】 以亚硫酸盐废液为物料,研究了蒸发器中流速、加热表面温度、溶液温度、固体含量、硫酸盐添加量及溶液的pH值等操作变量对结垢速率的影响.文中对结垢机理进行了探讨,最后提出了计算结垢速率的模型方程.
【Abstract】 The effects of possible operating variable such as flow rate, surface temperature, bulk temperature, solids contents, sulfate addition and pH on the fouling of sulfite spent evaporators were studied. In the paper, the fouling mechanism is discussed, then a model equation for calculating fouling rate is proposed.
