Abstract
Based on CFD numerical simulation technology,the law of static mixer for improving the velocity/concentration distribution characteristics in the inlet cross section of first catalyst layer of SCR denitration system is investigated systematically in this paper.Numerical calculation results show that the velocity/concentration distribution deviation can be improved by 8.89% and 12.26% respectively,and the elevated pressure loss of the whole system is about 188 Pa after the optimization of specific static mixer type.Therefore,we hold that the optimal layout of static mixer can significantly improve the velocity/concentration distribution within the cross section.However,based on the changing law of pressure loss of the system,we suggest that both the improvement performance of velocity/concentration distribution deviation and the changing characteristics of systemic pressure loss should be balanced in the process of static mixer design.关键词
