| 摘 要： | 在负压大的烟道中采集烟气时,由于现用采样泵的流速小于烟气流速而出现倒吸或采不到完整样品的现象,通过多次现场实验和理论分析,设计组装了简便的烟气采样辅助设备,解决了上述问题.

| Abstract: | As the sampling speed is often smaller than the speed of emission in the channels under negative pressures,suck-back will occur,then qon cannot get perfect samples.To solve these problems,we have designed a set of accessory equipment which is simple and easy to handle. |

| Keywords: | fixed pollution source negative pressure suck-back fume accessory equipment |
