一、引言粉尘是煤炭工业的一大危害,它给企业财产安全和矿工身体健康带来极大的威胁。为了有效地控制粉尘,首先必须及时、准确和自动地监测粉尘浓度。目前,测尘仪的研究、仿制和使用,愈来愈受到重视。但国内有关采用什么设备、如何鉴定测尘仪技术性能和各种实验、标定方法等的文献为数不多。为此,作些介绍。二、实验装置 1.粉尘发生器和气溶胶发生器美国GCA公司用来评定呼吸性粉尘监测仪RDM101—1型的实验设备见图1。粉尘 I. Introduction Dust is a major hazard to the coal industry, which poses a great threat to the safety of enterprises and the health of miners. In order to control dust effectively, it is first necessary to monitor dust concentration timely, accurately and automatically. At present, dust meter research, imitation and use, more and more attention. But the domestic use of what equipment, how to identify the technical performance of the dust meter and a variety of experiments, calibration methods, such as the literature is one of the few. To this end, for some introduction. Second, the experimental setup 1.
