为了能够直观、高效地测量煤矿井下浮游煤尘的浓度,准确及时地反映接尘人员吸入的呼吸性煤尘质量和采掘作业场所中煤尘的污染状况,设计一种基于红外光吸收法的煤尘测量装置,采用本安电路和恒流量控制的采样泵,对煤矿井下及其他含有爆炸危险性气体的作业场所可吸入性粉尘颗粒进行高效测量。该装置能快速直观地显示测量结果,并且具有串口通信、数据存储、打印接口等功能。将煤尘检测获得的数据结果用于煤矿井下的防尘治理,及时采取相应的防尘措施,有现实的意义。
In order to measure the concentration of suspended coal dust in the coal mine intuitively and efficiently, and accurately and timely reflect the quality of respirable coal dust inhaled by dust collectors and the pollution status of coal dust in the mining operation site, a coal based on infrared light absorption Dust measurement devices, using intrinsically safe circuits and constant-flow control sampling pumps, measure the respirable dust particles in the coal mine and other workplaces that contain hazardous explosive gases. The device can quickly and intuitively display the measurement results, and has a serial communication, data storage, print interface and other functions. It is of practical significance to apply the data obtained from coal dust detection to dust control in coal mines and to take appropriate dust control measures in a timely manner.
