This paper presents, at first, part of the data on the use of diesel-powered trackless mining equipment in 36 Swedish hardrock underground mines and the threshold limit values of diesel emissions in the underground mine atmosphere, drawn up by the Swedish National Board of Occupational safety and Health. It mentions the large amount of scientific research which has been carried out and is still being studied by designers, manufacturers, mines and research arganizations in order to satisfy these standards. The aims, tasks, fundamental equipment and research methods of diesel exhaust cleaning in the diesel engine laboratory of the University of Lulea are illustrated. It is pointed out that research on purifying diesel exhaust gases should be speeded up for solving the serious mine ventilation problem caused by the use of diesel-powered equipment. The paper concludes that efforts should be made to provide new facilities for efficient ventilation and to develop more modernized trackless mining equipment by increasing research work in the field of automatic ventilation control as well as the design and manufacture of new L H D machines, either diesel-electric-powered or electric-powered with trailing cables. Additional papers in this field of research will follow

文章首先扼要地介绍了瑞典全国三十六个地下金属矿山使用柴油无轨设备的部分统计资料,以及瑞典政府职业安全与健康局关于井下大气中柴油机废气的临界极限标准。指出,为达到这一标准,采掘机械设计制造部门、矿山、科研单位,已经并正在进行大量的研究工作。接着,比较系统地介绍了瑞典律勒欧大学柴油机废气净化实验室的研究任务、目的、基本设备和试验方法。最后,联系柴油无轨设备大量使用所引起的严重的通风问题指出,必须进一步大力开展柴油机废气净化的研究工作。并配合自动通风控制,研究柴油-电力驱动或电缆蒎筒式装运卸机等,将无轨开采技术装备推进到新阶段。

Analyses on the application of oxy-catalyst convertors in the purifieation system for low-pollutant

作者对催化转化法在井下低污染柴油机尾气净化系统中的应用,从三个方面进行了分析,即:由于现代低污染水冷柴油机的排气温度较低,明显降低了催化装置的实际净化效率;在现代低污染风冷柴油机的尾气中,测得NC_x的含量比CO、HC要高,从而为稀释NO_x所需的风量比稀释CO、HC所需的风量要大,因此再用催化法处理CO是不必要的;催化装置还将把柴油燃烧过程中产生的SO_2进一步氧化成毒性更大的SO_3,加重了井下空气的污染。因此,作者认为,对于现代低污染柴油机,在其尾气净化系统中应用催化法装置是没有必要的,较好的净化系统可以采用水箱洗涤和尾气扩散器,并适当增大稀释风量。

A comparison has been made between air cooled indirect injection (IDI) and water cooled, turbocharged direct injection (DI) diesel engines (the later both 2-stroke and 4-stroke cycle) from the standpoint of exhaust emission, fuel consumption, etc. These comparisons are made mainly on the basis of laboratory tests carried out at the uni- versity of Lulea, Sweden. Our measurements have confirmed that the hazard emissions from IDI engines are somewhat lower than those from DI engines. This is however balanced out important advantages of the 4-stroke cycle DI engines such as lower fuel consumption, lower pro- duction and maintenance costs, lower tare weight, etc. Now the future of the DI en- gine seems to be very bright because sophisticated techniques (the combination of tur- bocharging, air charge cooling and fuel injection) can lower also the NO_x emissions, so in the future it may be that DI engines will be considered more suitable for under- ground mining than the currently-favoured IDI engines.

在台架试验的基础上,从尾气浓度和燃油消耗等出发,对风冷间接喷射式柴油机(IDI)及水冷直接喷射式(二冲程及四冲程)柴油机(DI),进行了对比。测试表明,虽然间接喷射式柴油机排放的有害物质的浓度多少低于直接喷射式,但四冲程直接喷射式柴油机却具有油耗少,生产和维护费用低,以及自重轻等优点。随着技术的进展(透平增压、进气冷却和改善喷油系统),直接喷射式柴油机的NO_x浓度也巳经降低,这使直接喷射式柴油机的前景非常光明。因此,未来的直接喷射式柴油机,可能比目前受宠爱的间接喷射式柴油机,更适于地下矿山使用。
