Abstract

In this paper the optimization for the flow field of a preliminary design of SCR device was studied of a cement plant production line with Fluent, which mainly aims to solve the problem of uneven distribution of velocity field by designing the gate leafs’ and rectifiers’ layout. To solve the problem of non-uniformity of velocity in SCR reactor, the angle of the wedge SCR reactor was adjusted, three non-equidistance "flat type" layout straight-arc-straight guide were designed by the method of similar geometry at the first bend and "inclined top type" rectifier was installed. Finally, the area weighted uniformity index value was more than 0.9000 and the deviation angle was less than 10°, which provides ideas of the design and optimization method to the medium and small SCR reactors.
