采用多元回归的方法得出各影响因素与过滤效率呈显性关系的效率关联计算公式,以及颗粒层过滤器压力损失在稳态过滤及非稳态过滤过程的关联计算式,关联计算式计算结果与相关文献对比结果基本吻合。以过滤效率越高及过滤压力越低为目标函数,提出颗粒层性能优化计算模型,得出了提高颗粒层过滤性能的最佳参数。
Using multiple regression method to get the efficiency of each factor was significantly related to the efficiency of the relationship between the filter efficiency formula, as well as the particle filter pressure loss in steady-state filtration and non-steady-state filtration process correlation formula, the correlation calculation formula Comparison with the relevant literature basically consistent. Taking the higher filtration efficiency and the lower filtration pressure as the objective function, an optimization calculation model of particle layer performance was proposed, and the best parameters for improving particle filtration performance were obtained.
