| 摘 要： | 三相分离器是厌氧反应器的核心部件,三相分离器研究的重点和难点在于揭示气液固三相分离过程。文章通过建立冷模实验系统探究了三相分离器气体分离收集的过程,并考察了曝气量、进水量对气相带水量、气相带水能力、颗粒流失等三相分离器性能的影响。研究结果表明:气相在三角堰内完成分离收集然后汇聚到集气室内,最后夹带一定量的液体由提升管排出;随着曝气量的增加,气泡逃逸量有所增加,颗粒流失加大,气相带水量不断增加,但是气相带水能力先增加后降低;进水量的变化不影响三相分离器的运行效果。研究结果为三相分离器的设计及稳定运行提供了理论基础。

| Abstract: | Three phase separator is the key component in internal circulation anaerobic reactor.The performance of three phase separator was studied with an experimental device.The influence of the gas and liquid flow rate on the separator performance was investigated.The results showed that the gas was separated by the baffles and collected by the gas collection chamber,then the gas was entrained a certain amount of fluid and discharged through a riser.With the increase of gas flow rate,the gas bubble escape increased,the particle loss increased,and the water amount in the gas increased continuously.However,the water carrying capacity in the gas increased first and then decreased.The change of water inflow did not affect the operation effect of the three-phase separator. |
