Developments of Inverse Circulating Fluidized Bed and Innovative Powder Coating Technologies

虽然传统的气-固流化的原始概念已经被“扩展”到高速流化（通过增加速度）、液体和气-液-固流化（通过改变流化介质）以及下行床流化（通过改变流动方向），但液体向下流化较轻颗粒（否则将漂浮）的反向流化的概念仅受到有限的关注。 特别地，没有对高速反向流化进行研究。 这种新的反向液-固循环流化床，i-LSCFB，作为这里的第一个目的提出，将具有在两端互连的两个柱-下行床，其中液体和轻于液体的颗粒两者随着液体速度高于颗粒终端速度而向下流动，和提升管，其中液体向下流动，而颗粒向上流动，因为流化速度低于颗粒终端速度。 一旦开发出来，它将是世界上第一个，并可立即用于申请人发明的流化床废水处理技术-大大降低其能源消耗，但也可用于其他领域，特别是生物数据应用。

While the original concept of conventional gas-solid fluidization has been "expended" to high-velocity fluidization (by increasing velocity), to liquid- and gas-liquid-solid fluidization (by changing the fluidization media), and to downer fluidization (by changing flow direction), the concept of inverse fluidization with liquid fluidizing downwards lighter particles (which would be otherwise floating) has only received limited attention. In particular, no study has been conducted for high-velocity inverse fluidization. This new inverse liquid-solid circulating fluidized bed, i-LSCFB, proposed as the first objective here, would have two columns interconnected at the two ends - a downer where both liquid and lighter-than-liquid particles flow currently downwards as the liquid velocity is higher than the particle terminal velocity, and a riser where liquid flow downwards while particles flowing upwards because the fluidization velocity is lower than the particle terminal velocity. Once developed, it will be the world's first time and can be immediately used in the fluidized bed wastewater treatment technology invented by the applicant - to significantly reduce its energy consumption, but can also be used in other areas especially for bio-dapplications.
