摘要/Abstract

摘要： 为实现对隧（巷）道爆破CO的高效净化，基于CO光催化氧化技术，试验研究催化剂类型、光源参数、气体流量及反应温度对CO光催化净化效率的影响规律，据此设计研发隧（巷）道爆破CO光催化净化装置并对其开展现场试验。研究结果表明： 1）在ZnO、Pt/TiO₂、CuO/Al₂O₃ 3种催化剂中，金属负载型催化剂CuO/Al₂O₃对CO光催化反应具有最佳的催化性能，试验初始体积分数为8 000×10^-6的CO净化率可达99.41%； 2）光源的3个最优参数是波段为可见光（≥420 nm）、功率为266 W、光照距离为10 cm，可在9 min内将8 000 ×10^-6的CO净化至100×10^-6以下，净化率为99.45%； 3）气体流量降低、反应温度升高，CO光催化净化效率随之提高，且催化剂性能在100 ℃范围内未因高温而受到负面影响； 4）基于试验结果研发隧（巷）道爆破CO光催化净化装置，现场试验测得该装置对爆破后CO峰值体积分数与最低体积分数的平均净化率分别为58.55%和62.82%，净化效果显著。

Abstract: The drilling and blasting method is currently the primary method for tunnel and roadway excavation; however, the blasting process generates substantial amounts of carbon monoxide (CO), posing a significant threat to the safety and health of construction personnel. To achieve efficient purification of CO from tunnel/roadwway blasting operations, based on CO photocatalytic oxidation technology, this study experimentally investigated the effects of catalyst type, light source parameters, gas flow rate, and reaction temperature on the photocatalytic purification efficiency of CO. Based on these findings, a photocatalytic purification device for blasting-derived CO in tunnel/roadway was developed and empirically validated through field trials. This research reveals that: (1) Among the three catalysts tested—ZnO, Pt/TiO₂, and CuO/Al₂O₃—the metal-supported catalyst CuO/Al₂O₃ exhibits the highest photocatalytic activity for the CO reaction, achieving a CO removal efficiency of 99.41% at an initial concentration of 8 000×10^-6. (2) The three optimal operational parameters for the light source are: wavelength within the visible spectrum (≥420 nm), power of 266 W, and an illumination distance of 10 cm. Under these conditions, CO with an initial concentration of 8 000×10^-6 can be reduced to below 100×10^-6 within 9 minutes, corresponding to a removal efficiency of 99.45%. (3) A linear increase in CO photocatalytic purification efficiency was observed with decreasing gas flow rate and increasing reaction temperature. Furthermore, the catalyst’s performance remained unaffected by high temperatures within the tested range of up to 100 ℃. (4) Based on these experimental results, a photocatalytic purification device for tunnel/roadway blasting-derived CO was developed. Field validation confirmed substantial purification efficacy, with average removal rates of 58.55% for peak post-blasting CO concentrations and 62.82% for minimum concentrations.
