Abstract

In order to control the dust removal and desulfurization process accurately, it is imperative to obtain the optimal structure parameters of the valve, using CFD to simulate and forecast the flow field numerical design of dust removal and desulfurization of digital valve, designing the L₂₅(5⁶) orthogonal test table of valve structure, selecting the arc radius, length, angle, width as the factors. The study determined the flow characteristics, the ideal digital valve of the maximum open flow coefficient and the degree of the digital valve spool inertia as the performance evaluation index of the valve, completed the orthogonal experiment and analysed by range analysis of the results, and obtained the influence of structure parameters on the ranking optimization direction of evaluation index, the simulation forecast data in various opening of digital valve and the flow pressure nephogram and velocity contours of 100% relatively open. A comprehensive quality evaluation index of the valve was made, making the multiobjective optimization problem into a single objective optimization problem of desulfurization dust digital valve optimization through the synthetic weighted mark method. Using box method to optimize the structure of desulfurization and dust removal of digital valve, we obtained the optimal structure parameters: radius of 3.4mm, the angle of 108.05°, length of 14.07mm and width of 37.85mm.
