This technology is a spouted bed that incorporates vertical vibration to stabilize the spout, allowing for improved recirculation rate, range of operating conditions, and overall process efficiency.
Spouted beds often experience spout instability due to non-uniform gas flow, bed or inlet asymmetries, or particle agglomeration. These instabilities result in non-uniformity in industrial processing which is detrimental to process quality. Current methods to mitigate spout instability are either cost-prohibitive for industrial applications or reduce the recirculation rate, thus decreasing process efficiency. As such, there is a need for cost-effective strategies to mitigate spout instabilities that do not sacrifice efficiency.
This technology improves the efficiency of spouted beds by vertically vibrating the spout to mitigate spout deflection. This simple solution improves spout stability without the need for expensive equipment or limiting the recirculation rate. The result is increased particle homogeneity, faster recirculation, and an enhanced range of stable operating conditions, which increases the processing efficiency of spouted beds without significant cost. This technology has applications in industrial granulation, mixing, drying, coating, gasification, and pyrolysis processes.
