| 摘 要： | 针对固定污染源排气监测实际工作用S型皮托管测定静压方法有争议的问题进行了理论分析和低速风洞试验。结果表明,用S型皮托管测固定污染源排气静压的平行法和垂直法二方法都在不影响排气量和污染物排放量测定结果的范围内;用全压与平行法静压差作为动压来计算流速可影响较大。

| Abstract: | The theoretical analysis and low speed airhole experiment were made in view of controversy on static pressure detection for fixed pollution effluent by Pitot tube. The results showed that horizontal and vertical method for static pressure do not affect effluent emission detection, however the dynamic pressure with difference of full pressure and static pressure can affect flow. To minimize indefinite detection and normalize the monitoring, the Method on Particulate Detection and Air Pollutant Sampling for Fixed Pollution Source Effluent (GB/T16157-1996) should be adopted to detect static and dynamic pressure. |
