摘要
针对目前氧分析仪探头存在高温加热炉测量难及氧化锆易意外点火爆炸的问题,提出了一种优化方案。在传统测氧技术的基础上,采用恒流量抽取直吹法对预处理系统增设阻火器、高温过滤、二级恒温。运行结果表明,该优化产品不但解决了氧分析仪高温测量难的瓶颈,而且在彻底消除安全隐患的同时,提高了测氧精度和加热炉热效率,达到了降本增效、减少污染的效果,将占有举足轻重的市场地位。
At present, it is difficult to use the probe of oxygen analyzer in measurement for high temperature heating furnace, and the Zirconia may cause ignition explosion, thus an optimized scheme is proposed. On the basis of traditional oxygen measurement technology, by adopting constant flow direct blowing extraction method, several measures, including adding flame arrester, high temperature filtering, and secondary constant tempemture, etc. ,are conducted in pre - processing system. The mnning results show that the optimized product not only resolves the bottleneck of difficulty in high temperature measurement, but also eliminates the security risks, in addition, enhances the measurement accuracy and heat efficiency of the heating furnace; this satisfies the requirements of increasing efficiency and reducing cost and pollution. In future development of high tempemture constant oxygen measurement industry,the optimized product will occupy a pivotal position in the market.
