建筑室内污染物扩散模拟与控制

Indoor pollutant diffusion control and simulation in building

    摘要
  • 摘要: 对建筑室内香料污染物扩散的控制方法进行了研究.分析了香料污染物产生的根源和扩散特性,制定了分区控制、先收集后处理的控制策略.设计了排气柜排风系统,基于数值模拟优化了排风系统参数,确定了最优风道流速5.6~6.0m·s-1.实测结果表明,采用分区控制污染源,利用排气柜收集污染物是控制香料污染物扩散的有效方式,香料污染物收集率达90%以上.

     

    Abstract: The method to control diffusion of indoor perfume pollutants in building was studied.Production source and diffusion characteristic of perfume pollutants were discussed.The control plan was proposed that pollution sources were isolated separately and then pollutants were collected.The exhaust system was designed.The optimal flow velocity in pipeline was obtained to be 5.6-6.0 m·s-1 based on numerical simulation.Test results proved that more than 90% of perfume pollutants were trapped and the method was an effective way to control the diffusion of perfume pollutants.
