Study on flue gas Treatment System of diesel generator set
柴油发电机组烟气处理系统研究

摘要

为解决柴油发电机烟气温度高的问题，本文研究了一种基于溴化锂吸收制冷原理的降温方法。通过三级逆流换热器，二次对排烟余热进行降温；在排烟出口采用自吸式混新风对排烟进行三次处理；对外部通风排烟孔实施深埋分流伪装处理，实现了对柴油发电机组排出烟气进行降温。最后，利用原型机对处理效果进行了实验验证，结果表明，降温效果较为明显。

Abstract

In order to solve the problem of high temperature of diesel generator flue gas, a cooling method based on lithium bromide absorption refrigeration principle was studied. Through the three-stage countercurrent heat exchanger, the waste heat of exhaust smoke is cooled twice; The smoke exhaust outlet is treated three times by self-priming mixed fresh air. Deep buried shunt camouflage treatment was applied to the external ventilation vent to realize the cooling of the exhaust gas from the diesel generator set. Finally, the prototype is used to verify the treatment effect, and the results show that the cooling effect is more obvious.
