粉尘质量浓度的光纤光栅传感测量技术
|
摘要
粉尘质量浓度是粉尘爆炸的关键因素,针对目前对本质安全、可实时监测预警的粉尘质量浓度测量技术的迫切需求,提出一种基于光纤光栅和光纤准直器的新型测量技术,在阐述其测量理论的基础上,搭建测量和实验装置实物。对200、300和400目这3种粒径规格的小麦粉尘分别开展实验测量,结果表明:所提出的测量技术的光功率输出和粉尘质量浓度呈线性关系;并与标准的称重法得到的粉尘质量浓度开展对比,验证了光纤光栅测量技术的有效性。
Accidents resulting from combustible dust explosion occur frequently and pose a serious hazard to the safety of industrial production. Dust concentration is a critical factor involved in the explosion leading to such accidents,and therefore its precise and fast measurement can provide an intrinsically safe and real-time monitoring technology for preventing such accidents. In this paper,we proposed a new measuring technique based on the fiber Bragg grating and the optical fiber collimator. We first explained the measurement theory and constructed the measuring and experimental device,and then performed experiments on wheat dusts with three grain sizes of 200 meshes,300 meshes and 400 meshes and carried out the related investigation. The results show that the optical power output of the device and the dust concentration are linearly correlated. We also carried out contrastive experiments with the dust concentration obtained using the standard weighing method,and verified the effectiveness of the FBG measuring technique proposed. This study provides a new way to conduct dust concentration monitoring,and holds broad prospects for further research and application.
