新装房间内苯的释放规律和传输过程的CFD分析

CFD Analysis of Benzene Release and Transport Processes of New Room

现代的装修装饰材料会释放大量的有毒有害物质(如苯及苯系物),污染着室内环境。对于一个新装修的建筑房间,了解其室内建筑材料内苯及苯系物的散发特性和浓度分布规律,从而避免吸入过量的有毒有害物质的,成为人们越来越关心的事。以一户新装修的住宅为例,首先对该房间空气中的气态污染物进行数值模拟,然后分析污染物散发机理及空间传输过程,最后通过总结模拟计算的结果,对如何降低新装修房间内苯的浓度,提出了几点建议。

Modern decoration materials will release a large amount of toxic and hazardous substances（such as benzene and series of benzene-compound）,which pollute the indoor environment.For a newly decoration building room,it is very important to understand the emission characteristic and concentration distribution of benzene and series of benzene-compound of indoor building materials,for the reason that in order to avoid excessive inhalation of toxic and hazardous substances.This paper take a newly decoration housing for example.First of all,simulate the gaseous pollutants of the air in the room.And then analyze pollutant emission mechanism and transfer process.Finally,propose some suggestions about how to reduce the benzene concentration of newly decoration rooms by summarizing the results of simulation.
