- 摘要:
- 根据干馏工艺流程配入适量氧气，可以降低载热气体需要预热的温度，以实现低能耗、易于工业生产的特点，设计了一套新型的有氧干馏工艺流程。有氧干馏工艺因其过程中存在可燃性混合物，有发生爆炸事故的可能性，通过实验对所收集的不同温度下的干馏气体的成分与含量进行了分析，结合爆炸极限理论，对该有氧干馏工艺流程的不同温度、不同惰性气体含量条件下可燃气体爆炸极限进行了分析计算。结果表明，可燃气体的浓度在整个反应升温过程中始终没有进入爆炸危险区域，说明该实验装置不具备爆炸危险性；对干馏工艺流程中氧气的输入量的控制，可以防止该工艺流程的火灾爆炸的发生。
- Abstract:
- The main industrial utilization of oil shale is to produce shale oil through a retorting process.In order to lower the carrier gas temperature so as to save energy consumption and achieve better industrial application potential, moderate amount of oxygen was added to the carrier gas in the oil shale retorting process. And the potential security problems owing to combustible mixtures might occur. These tests focused on how gaseous products of thermal decomposition of oil shale changed depending on pyrolysis temperature. Explosion limits under different temperature and inert gas condition combining with theoretical study on explosion limits were analyzed and calculated. The results showed that H2, CH4 are the main combustible gas of the retorting process and the process caused no explosion hazards because of the concentration of flammable gas did not within the limits of explosion danger zone in the whole heating process. It was suggested to prevent explosive occurrence of that process by controlling oxygen flow. The results can give a reference to quantitative understanding gas release law in process of oil shale retorting under areobic condition and antiexplosion treatment.
