给入若干平行作业的矿浆给料的分配偏差被认为是选煤和选矿工业需要解决的一个问题。分配偏差导致多作业系统中的每一个作业(如水力旋流器、螺旋和浮选设备作业)具有不同的分离密度、粒度分布和固体浓度。从而使某些设备在远离合适的条件下运行,导致选煤厂中分级和选别设备效果显著下降。本研究的目的是为矿浆的均匀分配开发新的和更为健全的方法和设备。采用隔墙或分层器改进简单的T型分配器,产生了新型分配器。采用带T型分配器的垂直管道进行了一系列的试验,比较各种方法分配矿浆的效果。研究了流速、颗粒粒度、密度、固体浓度和分支取向的影响。结果表明,新型分配器对降低垂直T型分配器中矿浆的不均匀分配是有效的。也测定和比较了流体分配器的流体压降。
The deviation in the distribution of the slurry fed to several parallel operations is considered a problem to be solved in the coal preparation and dressing industry. Discrepancy distributions result in different separation densities, particle size distributions, and solids concentrations for each of the multiple operating systems (hydrocyclones, spirals, and flotation equipment operations). Leaving some equipment away from proper conditions, resulting in a significant reduction in the effectiveness of the classification and sorting equipment in the coal preparation plant. The purpose of this study was to develop new and more robust methods and equipment for the even distribution of pulp. The use of a partition or decker to improve a simple T-splitter resulted in a new splitter. A series of tests were conducted using a vertical pipe with a T-splitter to compare the effects of various methods of distributing the slurry. The effects of flow rate, particle size, density, solid concentration and branch orientation were investigated. The results show that the new distributor is effective in reducing the uneven distribution of slurry in vertical T-distributors. The fluid pressure drop of the fluid distributor was also measured and compared.
