| 摘 要： | 光闪烁法对湿烟气下小浓度烟尘含量检测的测量原理及装置实现过程。通过样机在实验锅炉上校核,并与电称低压冲击器(ELPI)及滤膜称重法的同步测试数据进行比对,拟合相关系数为0.994。实验结果证明,光闪烁法对烟气中颗粒物浓度的测量是可行的,并具有较高的准确性及灵敏度。同时给出了光闪烁法独有的信号及数据处理办法。

| Abstract: | The measurement principle and the realization of the device of the optical scintillation method for wet-small concentration exhaust gas are introduced in detail.The device is checked on the experimental boiler and compared with the synchronous data of ELPI and weighing filter membrane,and the correlation coefficient was 0.994.The experimental results show that the optical scintillation method is feasible and has higher accuracy and sensitivity.At the same time,the special signal and data processing methods of the light scintillation method are given. |
