Abstract:
According to the orthogonal experimental design method, Fluent was used to numerically simulate the two-phase flow of gas and liquid in wave-plate mist eliminator with different structural parameters and operation conditions in wet flue gas desulfurization system in order to optimize the design of mist eliminators. A prediction model for removal efficiency and pressure drop was established applying least square support vector machine from the results of numerical computation. The highest relative error between the predicted output and measured value is smaller than 2%. The prediction results show that not only the vane spacing and vane turning angles, but also flue gas velocity and water entrainment load play an important role in influencing the removal efficiency and pressure drop. It is consistent with some experimental and simulation conclusions. Based on the prediction model, a mist eliminator parameters optimization model was created employing genetic algorithm(GA)and the results show that eliminator performance can be improved obviously. The optimal solution and data analysis show that the model can direct the optimum design of mist eliminators.
