摘要
为了减少高层建筑混凝土扬尘污染,提出高层建筑混凝土扬尘污染监测及治理方法。采用气-固两相流原理分析高层建筑混凝土扬尘颗粒运动,通过高层建筑混凝土扬尘扩散过程分析扬尘颗粒在风力作用下的扩散规律,根据分析结果,结合Mie散射理论研究高层建筑混凝土扬尘的散射现象,采用Beer-Lamber定律计算高层建筑混凝土扬尘浓度,实现高程建筑混凝土扬尘污染的监测,并提出了治理高程建筑混凝土扬尘污染的方法。实验结果表明,所提方法可准确的监测高层建筑混凝土扬尘浓度、风向频率和污染面积。
In order to reduce the dust pollution of high-rise building concrete,the monitoring and treatment methods of high-rise building concrete dust pollution are proposed.The movement of dust particles in high-rise building concrete is analyzed by using the principle of gas-solid two-phase flow,and the diffusion law of dust particles under the action of wind is analyzed through the dust diffusion process of high-rise building concrete.The scattering phenomenon of high-rise building concrete dust is studied in combination with Mie scattering theory.The dust concentration of high-rise building concrete is calculated by beer Lamber law.This paper realizes the monitoring of dust pollution of elevation building concrete,and puts forward the method of controlling dust pollution of elevation building concrete.The experimental results show that the proposed method can accurately monitor the dust concentration,wind direction frequency and pollution area of high-rise building concrete.
