Abstract:

Through to the mixer of the selection of each component analysis and introduction, aiming at 10 in the desulfurization denitration common specifications of the limestone slurry tank, mixer technology selection on the optimization design, analyses how to do in the desulfurization denitration limestone slurry tank mixer optimization selection, so as to achieve the optimal land use effect and the technological requirement. At present, the selection of mixer and the design of its internal components are largely dependent on experiment and practical engineering experience. The advantages and disadvantages of product design can make the benefit of mixing equipment is very different, so on the basis of clear limestone slurry material properties, for each element of mixing equipment, such as the shape of the impeller, impeller diameter, layout layer number, speed, mixing shaft size, baffle size and number of one optimization. By making full use of the comparative analysis of existing achievements, the design and selection of ten common specifications and models of limestone grout box are optimized, so that the design theory of mechanical mixer is more perfect, and it can also meet the requirements of practitioners in the daily desulfurization and denitration industry on the selection of limestone grout box mixer.

Key words: desulfurization and denitration, limestone slurry box, blender, selection, optimization design

摘要：

通过对搅拌机各组成部分的选型分析与介绍，针对脱硫脱硝中10种常见规格的石灰石浆液箱，进行搅拌机工艺选型上的优化设计，分析在脱硫脱硝石灰石浆液箱中如何进行搅拌机的优化选型，从而达到最优的使用效果和工艺要求。目前，搅拌机的选型和内构件的设计很大程度上依赖试验和实际工程经验。产品设计的优劣可使搅拌设备的效益相差十分悬殊，因此本文在明确石灰石浆液物料性质的基础上，针对搅拌设备的各个要素，例如叶轮的形状、叶轮直径、布置层数、转速、搅拌轴大小、挡板的尺寸和个数等进行一一优化。充分利用已有业绩对比分析，对10种常见的石灰石浆液箱规格型号在设计选型上完成优化，使机械搅拌机的设计理论更加完善，也能满足日常脱硫脱硝行业中从业者对石灰石浆液箱搅拌机的选型需求。
