摘要:
除尘器内部流场的分布情况直接影响滤袋寿命和除尘效率. 针对布袋除尘器内部流场分布不均和滤袋底部含尘气流流速过高等问题,本文拟采用计算流体力学方法对除尘器内部气固两相流场进行数值模拟. 模拟结果表明:采用环形滤袋和5块水平导流板布置方案可以很好地改善除尘器内部流场的均匀性,同时显著降低了颗粒群冲击滤袋底部的强烈程度,为该布袋除尘器的结构优化提供理论依据.
Abstract:
The distribution of the inner flow field can directly influence the service life of the filter bag and the dust removal efficiency. In the light of these existing problems that the internal flow field distribution in bag filter is not uniform and the flue gas flow rate at the bottom of the filter bag is too high,the numerical simulation of filter internal gas-solid two-phase flow field is carried out by using computational fluid dynamics method. Simulation results indicate that the uniformity of flow field distribution in the bag filter can be improved by ring filter bag arrangement and 5 guide plates layout,meanwhile significantly reduce the intensity of the particle impact on filter bag bottom,and the conclusions provide a theoretical basis for the optimal structure design of bag filter.
