    摘要:

    随着经济的快速发展与能源供应相对不足的矛盾日益突出,柴油机废气余热回收利用越来越受到重视,针对钻井常用柴油机Z12V190耗油量大,热效率低,大部分热量以废气余热形势随废气排到大气中,能源浪费较大等问题,分析柴油机燃烧反应与废气成分,分别根据质量守恒定律和能量守恒定律,建立了废气排量计算模型和废气余热量计算模型,并举例计算分析发现:Z12V190柴油机废气排量较大,废气排量随废气含氧量增加急剧增加;废气余热量随废气排量增加呈线性增加;废气余热量较大,具有较好的经济开发前景,结合当前存在的利用柴油机废气余热热管锅炉、热力发电、热能储藏等实际应用,为钻井用柴油机废气余热回收利用做理论基础。

    Abstract:

    With the increasingly prominent contradiction between rapid development of economy and relative shortage of energy supply, the diesel engine exhaust gas waste heat recovery is being paid more and more attention. The Z12V190 diesel engine, which is widely used in oil, has the high fuel consumption and low thermal efficiency, and releases large exhaust gas waste heat into atmosphere to cause large energy waste problems. The diesel combustion reactions and exhaust gas components have been analyzed, the computational models of diesel exhaust gas emissions rates and exhaust gas waste heat rates have been built respectively according to the mass and energy conservation. A typical example shows some results as follows: firstly, the Z12V190 exhaust gas emissions rates are very large and have sharp increases with the increases of diesel exhaust O2 mass percentage; secondly, the increase of diesel exhaust gas emissions rates leads to the linear increase of waste heat rates; thirdly, the exhaust gas waste heat rates are so large that the waste heat recovery has good prospects for economic development with hot tube boilers, thermoelectric generators, heat energy store exchangers and modern air cooling and heating systems. It will reduce operation cost greatly by this way.
