本文重点研究安装在下方接收装置上的导流板的曲率对自由落体颗粒流粉尘量的影响。人为控制导流板曲率，限制自由落体散装物料与接收装置碰撞产生的扬尘方向。采用该方法提高了扬尘系统的扬尘排放效率，达到了节能减排的目标。采用实验方法探讨了导流板曲率与产尘量的关系。实验结果表明，当散装物料自由落体高度一定时，含有一定弧度的导流板抑尘效果更为显着。随着导流板曲率的增加，产尘量略有减少，然后迅速增加。当导流板曲率为0.045 cm-1或0.060cm-1时，产尘量最小，除尘效果显着。
This paper focuses on the study of the curvatures of deflector installed on the below receiving device to effect the dust amount from the free falling particle stream. The deflector curvature was artificially controlled to limit the fugitive dust direction which was generated by the collision between the free falling bulk materials and the receiving device. This method was used to improve efficiency of the dust control system to exhaust fugitive dust, and to achieve the targets of energy conservation and emissions reduction. The experimental method was adopted to explore the relationship between the deflector curvature and the producing dust quantity. The experimental results indicated that, the dust suppression effect containing deflector contained a certain radian was more remarkable, when the height of the free falling of bulk materials was constant. The producing dust quantity decreased slightly with the deflector curvature increasing, and then increased rapidly. When the deflector curvature was 0.045 cm-1 or 0.060cm-1, the minimum of producing dust quantity could be obtained, and the dust removal effect might be significant.
