摘要:
为探究医药工业领域生产工艺可能存在的粉尘爆炸危险性，采用20 L球形爆炸装置、1.2 L Hartmann试验装置、粉尘云最低着火温度测试装置（G-G炉）、粉尘层最低着火温度测试装置对阿卡波糖粉尘进行粉尘爆炸特性和热稳定性试验研究。研究结果表明：平均粒径52.6 μm的阿卡波糖粉尘最小点火能为30~100 mJ，粉尘云最低着火温度约为380 ℃，爆炸下限质量浓度45~50 g/m3，最大爆炸压力约为0.737 2 MPa，最大爆炸指数约为13.352 0 MPa·m/s，粉尘层最低着火温度大于400 ℃，约200 ℃开始发生热分解，放出热量约704.46 J/g；阿卡波糖是1种温度相对敏感、爆炸强度较弱、热分解较容易的粉尘。研究结果可为医药工业领域有效采取粉尘爆炸事故防控措施提供一定参考。
Abstract:
In order to explore the potential risk of dust explosion in the production processes of pharmaceutical industry,the explosion characteristics and thermal stability of acarbose dust were tested using a 20 L spherical explosion device,1.2 L Hartmann device,dust cloud minimum ignition temperature test device (G-G furnace),and dust layer minimum ignition temperature test device.The results show that the minimum ignition energy of acarbose dust with an average particle size of 52.6 μm is 30~100 mJ,the minimum ignition temperature is 380 ℃,the mass concentration of the lower explosion limit is 45~50 g/m3,the maximum explosion pressure is 0.737 2 MPa,the maximum explosion index is 13.352 0 MPa·m/s,the minimum ignition temperature of the dust layer is greater than 400 ℃,and the thermal decomposition begins at about 200 ℃,with the heat release amount of 704.46 J/g.Acarbose is a dust with relative temperature sensitivity,weak explosion intensity and easy thermal decomposition.The research results can provide some reference for adopting the effective prevention and control measures of dust explosion accidents in the pharmaceutical industry.
