摘要:
为降低铝合金湿式除尘系统发生氢气爆炸事故的风险，提出1种氢气抑制的方法用来降低铝合金湿式除尘系统发生氢气爆炸事故的可能性。选取柠檬酸钠作为抑制剂开展抑氢实验研究,得到不同浓度的柠檬酸钠溶液随时间变化的抑氢曲线。当柠檬酸钠溶液浓度为0.4~4 g/L时，能有效抑制铝合金粉尘与水的反应。通过扫描电子显微镜(scanning electron microscope，SEM)和能量色散谱（energy dispersive spectroscopy，EDS)分析对铝合金粉与柠檬酸钠溶液反应后的产物进行表征。最后，对本文提出的抑氢方法的经济性进行分析，明确该方法在节约安全投入方面具有非常明显的优势。抑氢本质化安全设计方法为控制铝合金湿式除尘系统氢气爆炸事故提供了1种新的思路，同时也可被控制核反应堆氢气爆炸事故所借鉴。
Abstract:
In order to reduce the risk of Hydrogen explosion in the wet dust removal system of Aluminum alloy,a method of Hydrogen suppression was proposed to reduce the possibility of Hydrogen explosion accident in the wet dust removal system of Aluminum alloy.The sodium citrate was selected as the inhibitor to carry out the experimental study of Hydrogen inhibition,and the Hydrogen inhibition curves of sodium citrate solution under different concentrations with time were obtained.When the concentration of sodium citrate solution was 0.4~4 g/L,the reaction between Aluminum alloy dust and water could be effectively inhibited.The reaction products of Aluminum alloy powder and sodium citrate solution were characterized by the scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS).Finally,the economy of the proposed Hydrogen suppression method was analyzed,and it was clear that this method had obvious advantage in saving the safety investment.The intrinsic safety design method of Hydrogen inhibition provides a new idea for controlling the Hydrogen explosion accident in the wet dust removal system of Aluminum alloy,and can also be used for reference in controlling the Hydrogen explosion accident of nuclear reactor.
