In order to obtain the sulphur removal with controllable fan's optimal control structure, we designed the structure according to the given conditions, determined the structure and performance indicators, and got the fan structure parameters which are used for the three-dimensional entity modelling. The fan flow field was studied by numerical simulation. Designing the fan's L9(34) orthogonal test table, choosing the impeller diameter, blade import installation angle and outlet blade installation angle for the orthogonal experiment of four factors, completed the orthogonal experiment and analysed the experimental results to get the process parameters optimization direction of each evaluation index influence situation. By using genetic algorithm to multi-objective optimization of fan noise and efficiency, we obtained the optimum technological parameters of centrifugal fan impeller combination as: the impeller diameter 1.18 mm, the impeller diameter imported 0.33 mm, inlet installation angle 31.69°, and the outlet blade installation angle 82.66°. Based on the flow field simulation and use of the numerical analysis principle, the performance prediction model of fan efficiency desulphurization and dust removal was obtained.Keywords

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.Keywords
