水泥窑烟气布袋除尘器模拟及导流设计

Simulation and Deflector Design of Bag Filter for Flue Gas of Cement Kiln

水泥行业常用的除尘技术是布袋除尘器,影响布袋除尘器除尘效率的因素有布袋的性能、温度的控制、粉尘的性质,在此基础上,流场的均匀性也会影响除尘效率.通过设计导流装置对除尘器内部流场进行优化,采用计算流体技术对内部结构不同的除尘器进行数值模拟分析,对比出最优方案,保证除尘效率,从而从理论上指导烟气除尘设备的设计.

The commonly used dedusting technology in the cement industry is the bag filter,and the factors affecting the dedusting efficiency of the bag filter are the performance of the bag,the control of temperature,and the nature of the dust.Besides,the uniformity of the flow field also affects the dedusting efficiency.By designing the flow guide device to optimize the internal flow field of the bag filter,the computational fluid technology is used to numerically simulate and analyze the bag filter with different internal structures.The optimal scheme is compared to ensure the dedusting efficiency,so as to theoretically guide the design of the flue gas dedusting equipment.
