摘要:
为了减少湿式除尘系统发生氢气爆炸事故的可能性,提出通过抑制湿式除尘系统中铝粉与水反应的方法来从本质上加以控制。选取木质素磺酸钙为抑制剂,利用研发的金属粉与水反应产生氢气测试仪进行氢气抑制实验,得出不同浓度木质素磺酸钙溶液随时间变化的抑氢曲线,表明木质素磺酸钙能较好地抑制铝粉和水反应产生氢气。使用扫描电子显微镜(Scanning Electron Microscope,SEM)和傅里叶变换红外光谱法(Fourier Transform Infrared,FTIR)对铝粉与木质素磺酸钙溶液反应后的产物进行表征,研究木质素磺酸钙的抑制机理。研究结果表明:可以将木质素磺酸钙应用到铝制品抛光打磨场所的湿式除尘系统中,从而降低氢气爆炸事故发生的可能性。
Abstract:
In order to reduce the possibility of hydrogen explosion accident, it was proposed to control essentially through inhibiting the reaction of aluminium powder and water in the wet dust removal system. The calcium lignosulfonate was selected as the inhibitor, and the experiments of hydrogen inhibition were carried out by using the selfdeveloped tester of hydrogen generation by the reaction of metal powder and water. The curves of hydrogen inhibition by the calcium lignosulfonate solution with different concentrations against time were obtained, which showed that the calcium lignosulfonate could inhibit the hydrogen generated by the reaction of aluminium powder and water well. The products after the reaction of aluminium powder and calcium lignosulfonate solution were characterized by using the scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) methods, and the inhibition mechanism of calcium lignosulfonate was studied. It was proved that the calcium lignosulfonate can be used in the wet dust removal system at the polishing and grinding places of aluminium product, so as to reduce the occurrence of hydrogen explosion accident.
