水煤浆水冷壁气化装置实用性技术创新改造总结

山西阳煤丰喜泉稷能源有限公司气化装置配套2台单喷嘴水煤浆水冷壁气化炉(晋华炉2.0技术,两开无备),自2015年12月气化装置投料以来,实际生产中气化装置主要存在五大类问题——工艺设计缺陷(1台中压氮气压缩机配套2台气化炉设计缺陷、气化炉高压氮气分支管线设计缺陷)、设备设计缺陷(合成气洗涤塔关联管线设计缺陷、真空闪蒸罐下液管设计缺陷)、制浆系统缺少提浓设备致水煤浆浓度低、絮凝剂和分散剂加入量在线监测不完善、锁斗排渣系统不清洁环保。为此,泉稷公司基于日常工艺操作及设备检维修等经验与摸索,进行了一系列有针对性的实用创新优化改造,确保了气化装置的安、稳、长、满、优运行。

Simulation and formability analysis of drawing process for automotive B-pillar

The numerical simulation on drawing process of automotive B-pillar was carried out on AutoForm software,and dangerous forming areas were discovered.The processing parameters,such as the layout of drawbeads,blank holding force and the shape of blank,were adjusted and optimized according to the simulation results.Results indicate that the quality defects can be forecast and removed,which improves the stability of forming process.The cost of design is decreased and the research cycle is shortened.It is proved that the drawing process and die design of B-pillar forming are feasible in actual production.
