涡流混合器论文文献综述
陈文瑞,刘德庆,廖丽敏[1]（2017）在《涡流混合器积灰堵塞原因分析》一文中研究指出对广西部分燃煤锅炉SCR反应器中涡流混合器积灰堵塞原因进行分析。结合硫酸氢铵的生成机理,通过在涡流混合器附近建立κ-ε湍流模型并计算该区域的温度场,发现涡流混合器圆盘附近的温度过低是造成涡流混合器积灰堵塞的主要原因。通过增加喷氨管在烟道内的长度,可有效地防止液态的硫酸氢铵生成,从而解决涡流混合器积灰堵塞问题。(本文来源于《广西电力》期刊2017年03期）
Rikard,Meyer,Noren（诺仁）[2]（2014）在《多进口涡流混合器的表征》一文中研究指出Process intensification is a emerging field in chemical engineering trying to improve the effectiveness of production in the chemical engineering industry. One way of achiev-ing this is miniaturising the equipment by using micro reactors which have been shown to give very low mixing time due to their initially small length scales. To add to the quickly increasing amount of knowledge in the field of micro reactors this study char-acterised the mixing effectiveness of different geometry modifications of a Multi-Inlet Vortex Mixers (MIVMs) using a the fourth Bourne competitive reaction scheme. Com-putational Fluid Dynamic (CFD) simulations of the reaction in the mixers was also produced and showed good agreement with experimental values for segregation index. Three different geometry modifications, scale up and down was also tested using CFD. Using the Interaction by Exchange with the Mean (IEM) method the characteristic mix-ing time for the mixers was found and compared with results from previous studies. It could be concluded that the MIVM is not comparable to true micro-scale mixers but give good mixing relative to its mass flow rate. Reducing the mixing chamber diameter or increasing the outflow diameter proved to give the best mixing performance while bigger inlets and size had smaller effect. This was found to be an effect of that more of the reaction took place where the energy dissipation is highest giving faster mixing. Finally a simple scaling law using the available data was used to facilitate future design.(本文来源于《华东理工大学》期刊2014-03-14）

Process intensification is a emerging field in chemical engineering trying to improve the effectiveness of production in the chemical engineering industry. One way of achiev-ing this is miniaturising the equipment by using micro reactors which have been shown to give very low mixing time due to their initially small length scales. To add to the quickly increasing amount of knowledge in the field of micro reactors this study char-acterised the mixing effectiveness of different geometry modifications of a Multi-Inlet Vortex Mixers (MIVMs) using a the fourth Bourne competitive reaction scheme. Com-putational Fluid Dynamic (CFD) simulations of the reaction in the mixers was also produced and showed good agreement with experimental values for segregation index. Three different geometry modifications, scale up and down was also tested using CFD. Using the Interaction by Exchange with the Mean (IEM) method the characteristic mix-ing time for the mixers was found and compared with results from previous studies. It could be concluded that the MIVM is not comparable to true micro-scale mixers but give good mixing relative to its mass flow rate.
