| 摘 要： | 本文描述通风除尘中气固两相流动的运动规律，导出了湿式除尘器分级效率的计算公式；确定了湿式除尘器中只要满足斯托克斯数Ｓｅｋ、颗粒雷诺数Ｒｅｓ、惯性碰撞参数Ｋｐ、液滴斯托克斯Ｓｔ等相似准则数，以及几何条件和单值条件相似，才能正确反映气流运动的实际情况，保证同类型湿式除尘器中具有相同的阻力和分级效率计算公式，并通过实验证实了其相似理论的正确性。图３，参５。

| Abstract: | In this paper, the movement law of gas-solid two -phase flow in ventilation dust suppression are described. The calculating formulas of fractional efficiency in the wet scrubbers are determined. When the similarity of the Stokes number Stk, particle Reynolds number Res, inertia Collision number Kp and droplet Stokes number St, and the similarity of the geometric and singular condition are contended, the practical state of gas flow movement is accurately reported, the same calculation formulas of the resistance and fractional efficiency are assured in the samc kind of wet scrubbers. And the accuracy of the similar theoretica are verified by experiments. 3figs. 5refs. |
