To solve the fire and explosion risks caused by hydrogen generation of Al alloy dust in wet dust collector systems, an attempt is made to use blueberry anthocyanin (B-ACN), as a non-toxic and environmentally friendly inhibitor for hydrogen generation of Al alloy dust. Hydrogen inhibition effect and mechanism are evaluated through hydrogen production experiments, hydrolysis kinetic models, surface characterization analysis, and adsorption model. The results show that B-ACN exhibited a potent hydrogen inhibition efficiency of 97.36% at 4.50 g/L concentration, and maintained a hydrogen inhibition stability higher than 94.21% under temperature disturbance. In addition, theoretical calculations and surface characterization were performed to investigate the inhibition mechanism of B-ACN. SEM-EDS and XRD confirmed that the surface of the hydrolysis products of Al alloy dust in B-ACN solution is smooth and complete, with almost no generation of hydroxides. FTIR indicated that B-ACN adsorbs on the dust surface through the O atom. XPS and adsorption model suggested that the surface adsorption of B-ACN on the Al alloy dust involves both physical and chemical processes and follows the Langmuir adsorption model. Therefore, a dense and complete B-ACN protective film formed on the surface of Al alloy as a physical barrier, blocking the reaction between Al and water molecules. This research provides a cost-effective, sustainable natural plant extract inhibitor to solve the risk of hydrogen generation and explosion, thereby achieving inherently safer industrial production and environmental protection.

蓝莓花青素作为绿色强效抑制剂在湿式铝合金除尘器系统中的抑氢性能

针对湿式除尘器系统中铝合金粉尘产氢引起的火灾爆炸风险，尝试使用蓝莓花青素（B-ACN）作为无毒环保的铝合金产氢抑制剂灰尘。通过产氢实验、水解动力学模型、表面表征分析和吸附模型评估氢抑制效果和机理。结果表明，B-ACN在4.50 g/L浓度下表现出97.36%的强效抑氢效率，并在温度扰动下保持高于94.21%的抑氢稳定性。此外，还进行了理论计算和表面表征来研究B-ACN的抑制机制。 SEM-EDS和XRD证实，铝合金粉末在B-ACN溶液中水解产物表面光滑完整，几乎没有氢氧化物生成。 FTIR表明B-ACN通过O原子吸附在粉尘表面。 XPS和吸附模型表明B-ACN在铝合金粉尘上的表面吸附涉及物理和化学过程，并且遵循Langmuir吸附模型。因此，在铝合金表面形成致密完整的B-ACN保护膜作为物理屏障，阻止Al与水分子的反应。该研究提供了一种经济高效、可持续的天然植物提取物抑制剂，以解决氢气产生和爆炸的风险，从而实现本质上更安全的工业生产和环境保护。
