Design and Performance Investigation on a Novel Air Filter

为了解决传统空气滤清器存在的压力损失较大问题,文章提出了一种新型空气滤清器,并对其结构参数进行优化设计;然后,采用k-ε模型及多孔介质模型对空气滤清器流场进行模拟,最后通过实验对模拟结果进行了验证。结果表明:数值模拟具有较好的准确性,相比于常规空气滤清器,新型空气滤清器提高了流场的均匀性,降低了压力损失,有利于提高过滤效率,减小过滤负荷,延长产品使用寿命。

In order to solve the existing problems of larger pressure loss in conventional air filter,a novel air filter is proposed and optimally designed in the paper.Then,the k-εmodel and porous medium model are used to simulate the flow field of the conventional air filter.The simulation results are verified by the experiment.The results show that the numerical simulation has good accuracy.Compared with the conventional air filter,the new air filter improves the uniformity of the flow field,reduces the pressure loss,improves the filtration efficiency and reduces the filtration load.Extend the service life of the product.
