Description

technical field [0001] The invention relates to the field of fluidized bed monitoring, in particular to a fluidized bed comprehensive monitoring system and method for tracking particle and spray motion. Background technique [0002] The fluidized bed is a reactor that uses gas or liquid to pass through the granular solid layer to keep the solid particles in a state of suspension and movement, and to perform a gas-solid phase reaction process or a liquid-solid phase reaction process. In a fluidized bed, particle movement is extremely complex, and it is difficult to track fluidized particles using non-invasive monitoring methods. Therefore, accurate observation of the movement state of fluidized particles and spray is particularly important for scientific research and digital simulation at the micro-scale level. At present, conventional methods can only measure the single-phase motion state of solid fluidized particles or spray, and it is more difficult to monitor the three-di...
