Gas-solid flow characteristics in downstream reactor

Gas-solid flow is the basic condition for the reactor to achieve its functions. This article conducted cold state experiments on a Single-layer Downstream Reactor, based on which, the gas-solid flow characteristics inside the reaction chamber were revealed and analyzed. The results indicate that the occurrence of an "inflection point" in the bed pressure drop pulsation signal is a key characteristic to achieve bed flow; The particle concentration in the feed end, middle area, and discharge end of the reaction chamber decreases sequentially. Compared to simple fluidization, the energy concentration frequency domain under gas-solid flow expands to 0-3.5 Hz. The apparent particle concentration in the reactor increases with the increase of feed rate and decreases with the increase of fluidization gas velocity. This study reveals the gas-solid flow behavior in downstream reactor, which has certain guiding significance for the process control of Downstream Hydrogen Mineral Phase Transformation Equipment.
