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, analyzes 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. The operation performance of the mixer is directly related to the quality, energy consumption, and production cost of the product. The engineering and academic circles have attached great importance to the mixing, conducted a lot of research work, and achieved a lot of research results. But in fact, stirring process is often accompanied by reaction process, its complexity lies in its principle involves flow field, fluid mechanics, heat transfer, mass transfer, and chemical reaction and other processes. In addition to the complexity of the material flow in the mixing equipment, it is a very complex mixing state, mixing effect is difficult to quantify through the form and size of the mixer, so as to complete under a strict theoretical guidance. 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 10 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.
