污水油泥掺配水煤浆气化数值模拟研究

摘要

Based on the analytic data of the oil sludge of Ordos basin oilfield and its mixture with coal water slurry, using the ANSYS Fluent to simulate the high temperature gasification of the coal water slurry (CWS) and the CWS with the oil sludge of 5%by mass in the entrained-bed. The results show that more effective gas (CO+H2) and higher carbon conversion are obtained from the oil sludge-mixed CWS than the CWS. The volume fraction of effective gas in the crude gas increases from 81% of CWS to 86% of the oil sludge-mixed CWS with a little increase of CO and a little decrease of H2 and H2O. Thus, the cogasification can improve the gasifier operation economy and is beneficial to energy saving and environmental protection.%在对炼油厂典型污水处理油泥及其掺配水煤浆产物分析的基础上,基于ANSYS Fluent模拟平台,对空白水煤浆及掺配5%油泥水煤浆进行气流床高温气化数值模拟研究.研究结果表明:含油泥水煤浆较空白水煤浆提高了碳转化率及有效气含量,粗煤气中有效气(CO+H2)体积分数从81%提高到86%,组分中H2和H2O成分有所下降,CO含量有较小增大趋势,从而提高了气化炉运行的经济性并达到节能环保的效果.
