Abstract

To address the issue of excessive CO emissions in the exhaust of explosion-proof diesel vehicles used in mining operations, this study developed and optimized an exhaust CO purification device featuring a Co3O4 monolithic catalyst core. The internal structure and external water-cooling system of the device were refined through numerical simulation. Field tests demonstrated that when the vehicle was equipped with the exhaust gas purification device, the maximum CO removal efficiency reached 97.7 %. During underground operations, the highest CO purification efficiency reached 64 %, while during coal shoveling activities, the average CO purification efficiency was 52.2 %. The device is of great significance for improving the underground working environment and ensuring the life, health and safety of personnel.

工业运输车辆废气净化装置优化及CO催化消除研究
针对矿山作业防爆柴油车尾气CO排放超标的问题,本研究开发并优化了一种采用Co3O4整体式催化剂芯的尾气CO净化装置。通过数值模拟对该装置的内部结构和外部水冷却系统进行了细化。现场试验表明,车辆配备尾气净化装置后,CO去除率最高可达97.7%。地下作业时CO净化效率最高,达到64%,铲煤作业时CO净化效率平均为52.2%。该装置对改善井下作业环境,保障井下人员的生命、健康和安全具有重要意义。

期刊介绍: Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
