工业车间粉尘的危害性众所周知：导致作业人员发生呼吸道感染、尘肺病等严重职业性疾病；一旦浓度超限遇热引起剧烈爆炸性事故；也是我国大部分地区空气污染或雾霾天气的主要推手。本项目旨在探索车间工业粉尘逸散过程的共性机理、运动规律和散尘量计算方法，提出控制工业粉尘的高效通风设计原理与方法，改善工业生产卫生环境。因此，该项研究是一项具有重要工程应用意义和学术理论意义的课题。.本研究旨在通过理论解析、CFD模拟，试验室测试和典型工业厂房现场测试：.（1）查明工业厂房多种形态粉尘逸散机理；.（2）建立粉尘污染逸散、浓度分布及散尘量计算方法；.（3）确定通风气流对粉尘污染扩散影响机理及控制方法；.（4）提出防控粉尘职业性危害的高效通风设计原则与方法。

Project title：Dust emission and controlling mechanism by ventilation based on the industrial handling process.. It is generally known that the harmfulness of industrial workshop dust can cause workers occupational diseases, such as respiratory infections and pneumoconiosis, etc. While exceeding concentration limits, it can cause explosive accidents. Dust from industrial workshops is also the main culprit of air pollution and smog weather in most parts of China. This project aims to explore the industrial workshop dust common mechanism in the process of dissipation, laws of movement and calculation method of dust bulk quantity; propose the principle and design method of high performance ventilation for industrial dust control including line source, surface source, volume source and their combined forms; improve industrial production and hygienic conditions. Therefore, this study is of significance with both engineering application and theoretical subject.. Through theoretical analysis, CFD simulation, laboratory tests, and a typical industrial plant field tests, it aims to:..-indentify the dust escaping mechanisms for various forms of industrial plants (line source, surface source, volume source and their combined forms);..-establish the calculation method of dust dispersion, concentration distribution and dust bulk quantity;..-determine the effects of airflow on dust pollution diffusion mechanisms and control theory;..-propose the principle and design method of high performance ventilation for controlling occupational hazards.
