An investigation was conducted on a self-agitation anaerobic baffled reactor (SA-ABR) with agitation caused solely by the release of stored gas. The compound in the reactor is mixed without the use of any mechanical equipment and electricity. The computational fluid dynamics (CFD) simulation used to provide details of the flow pattern and information about the agitation process and a solid basis for design and optimization purposes. Every self-agitation cycle could be separated into the pressure energy storage process, the exergonic process and the buffer stage. The reactor is regarded as the combination of continuous stirred tank reactor and a small plug flow reactor. The liquid level and diffusion varies widely depending on the length of the U-tube. The compound transition phenomenon in the 1st chamber mainly occurs during the energy exergonic process and buffer stage. The fluid-diffusion in the 3rd and 4th chambers mainly happens after the buffer period.
对仅由储存气体释放引起搅拌的自搅拌厌氧折流反应器(SA-ABR)进行了研究。该反应器中的混合物无需使用任何机械设备和电力进行混合。计算流体动力学(CFD)模拟提供了流动模式的细节以及搅拌过程的信息,为设计和优化提供了坚实的基础。每个自搅拌周期都可以分为压力储能过程、放能过程和缓冲阶段。该反应器被视为连续搅拌釜式反应器和小推流反应器的组合。液位和扩散随 U 型管的长度而变化很大。在第 1 个隔室中,化合物的转化现象主要发生在能量放能过程和缓冲阶段。第 3 和第 4 隔室中的流体扩散主要发生在缓冲期之后。
