【摘要】：目的通过正己烷实时监测系统,建立工作场所正己烷危害预防控制模型。方法利用传感器网络技术实现对工作场所正己烷的实时监测,通过风险评价,建立正己烷职业危害预防控制模型。结果正己烷实时监测系统的硬件包括数据采集器、数据传输及接收单元,软件系统由系统软件和手机APP软件组成。该系统可实时检测和动态观察工作场所空气中的正己烷水平和环境条件参数(温度、湿度、光强和风速),可直接导出正己烷的时间-浓度曲线图,分析正己烷水平与各种监测指标的关联性,并可对正己烷危害进行风险评价和预测。与国家标准方法比较,8个正己烷样品的检测结果相对误差范围为-3.2%~4.7%,含多种成分的3种正己烷混合有机溶剂的检测结果相对误差分别为-2.3%、3.8%和4.4%。结论正己烷实时监测系统可应用在企业的日常预防控制工作中,有利于做好职业性正己烷危害防治工作。
[Abstract]:Objective to establish the hazard prevention and control model of n-hexane in workplace by means of real-time monitoring system of n-hexane. Methods the real-time monitoring of n-hexane in workplace was realized by using sensor network technology, and the model of occupational hazard prevention and control of n-hexane was established by risk evaluation. Results the hardware of n-hexane real-time monitoring system consists of data collector, data transmission and receiving unit. The software system is composed of system software and mobile phone APP software. The system can real-time detect and dynamically observe the level of n-hexane and environmental parameters (temperature, humidity, light intensity and wind speed) in the air of workplace. The time-concentration curve of n-hexane can be derived directly. The correlation between n-hexane level and various monitoring indexes was analyzed, and the hazard of n-hexane could be evaluated and predicted. Compared with the national standard method, the relative error range of the eight n-hexane samples was -3.2and 4.7, and the relative error of the three n-hexane mixed organic solvents containing various components was -2.3% and 4.4%, respectively. Conclusion the real time monitoring system of n-hexane can be used in the daily prevention and control of occupational n-hexane, and it is beneficial to the prevention and control of occupational n-hexane hazards.
