stub tube fillers have practical significance for the removal of turbidity.
短管填料对水浊度去除有着重要的实用意义。
the stub tube fillers generated resistance of water flow. and the resistance increased with the increment of flow rate, the length of packed beds and the proportion of fillers.
短管填料对水流产生阻力,随水流速度、填料床的长度及填料投配率的增加而增大。
through controlling different flowing state of the influent, adding methods and position of the stub tube fillers, the best method of improving the removal rate of turbidity was proposed.
通过控制不同进水流态、短管填料不同投加方式、不同投放位置、不同投放量的对比,提出提高浊度去除率的最优方法。
results show that aligning heating device center and weld center, and heating main tube along stub tube root locally to 520~580 ℃, can prevent the maximum temperature excursion.
结果表明:加热装置的中心与焊缝中心重合,主管沿接管座根部局部附加加热至520~580℃时,可较好地克服最高温度偏移。
