摘要
航天粉煤气化技术采用传统粗合气洗涤流程,存在粗合气灰含量高,影响洗涤设备使用寿命等问题。为此,利用Aspen Plus模拟软件,结合旋风分离器的分离特性,提出了旋风分离器置于文丘里洗涤器前、后两种优化方案,并分别讨论了其优缺点。结果表明,两种优化方案均能大幅降低粗合成气含尘量,提高粗合成气的洗涤效果,为航天粉煤气化装置的工艺流程改进提供了方向。
Conventional crude syngas wash process is adopted for HT-L pulverized coal gasification unit, having the issue of high ash content of crude syngas, affecting the service life of the washing equipment. For this reason, by utilizing Aspen Plus simulation software and combining the separation properties of cyclone separator, two optimization schemes are proposed： put the cyclone separator before and after the washer. Their respective advantages and disadvantages are discussed. The results show that both optimization processes can greatly reduce the dust content in the crude syngas and increase washing effect of the crude syngas. It provided the direction for future improvement of HT-L pulverized coal gasification process.
