汽车电站排放烟度与温升的控制技术

Control Technology of Smoke and Temperature in Automobile Power Unit

针对汽车电站柴油发电机组排烟所带来的烟度与温升问题,通过光学和红外控制机理的研究,设计出系统控制方案.实验结果表明,采用岩棉材料保温、DPF和袋式金属纤维两路过滤净化、水洗消烟系统过滤降温的方式,可以达到良好的净化、降温的效果.经测试,采用了该控制方案后,排气背压低于14 kPa,过滤效率高达99%,降温幅度在85%以上.

Aimed at the problems of smoke degree and temperature increasing brought by exhaust of smoke from the diesel generator groups in the automobile power unit, the project of controlling the system was designed by researching the optics and infrared control mechanism. The experiment proves that through the way of using rock wool to maintain the temperature, using the DPF and bag metal fibers to filter, and using the washing smoke system to lower temperature and to filter, could achieve good cleaning and cooling effect. Test results show that the exhaust backpressure is less than 14 kPa, the filtration efficiency is up to 99 %, and the temperature range is more than 85 %.
