背景技术
目前城市雾霾,污染物积聚等问题严重影响到了城市居民的身心健康,成为了我国当前急需解决的问题。然而,在风洞试验中由于试验设备和试验技术的限制,对污染物扩散的合理模拟还非常困难。有些研究机构采用PIV对污染物进行模拟,但其造价非常昂贵,得不到广泛应用。常规的污染物发生系统一般以定性为多,只能较好的得到污染物的分布趋势,得不到模拟区域的污染物详细分布数据,同时,相应的污染物源产生和监测系统还非常少见。
因此,提供一种风洞试验的污染物产生系统和监测系统,以解决现有技术所存在的上述缺点,成为现在亟待解决的技术问题。
发明内容

优选的,所述混合装置为磁珠玻璃瓶,设置在所述污染物发射器前;所述气泵、甲烷供气罐与所述磁珠玻璃瓶连接的管道上均设置有流量计,所述磁珠玻璃瓶与所述污染物发射器之间设置有流量计。
本发明还公开了一种包括上述风洞试验污染物产生系统的风洞试验污染物监测系统,还包括:风洞和污染物浓度监测系统,所述污染物浓度监测系统设置在所述风洞内;所述污染物浓度监测系统包括监测管、采集袋和色谱分析仪,所述监测管设置在所述风洞内的模拟区域内,所述监测管的尾端与所述采集袋连接,所述采集袋还与所述色谱分析仪连接。
优选的,所述监测管设置有多个,多个所述监测管通过采集耙固定在所述风洞内的固定架上。

优选的,还包括计算机,所述色谱分析仪与所述计算机连接。
本发明相对于现有技术取得了以下技术效果:
1、设置有磁珠玻璃瓶,由于磁珠对气体的扰动作用,使得气体充分紊乱;磁珠玻璃瓶之后设置有螺旋管使两种气体充分汇合,从而产生均匀稳定的污染源;
2、通过色谱分析仪对风洞内气体进行色谱分析,能够直观形象的得到模拟区域的污染物浓度的分布。
