Fluidized bed with high effective bubble breaking member

The utility model relates to a fluidized bed with a high effective bubble breaking member. The lower part of a reaction casing of the fluidized bed is provided with a gas inlet, a gas distributing plate and a feeding device; solid granular catalysts are arranged on the upper face of the distributing plate, a gas and solid separator and a reaction gas product outlet are arranged at the upper part of the reaction casing, and a thick phase zone is provided with a multi-layer multi-rotation horizontal guiding rotating net of which the structure can form a small louver combining body with more than two rotating centers. The utility model has the characteristics that the fluidized bed can effectively reduce the diameters of bubbles, raise the solid phase contacting effect and improve the fluidizing quality without generating thermal deformation. The utility model is suitable for the distribution of wide granularity, and has wide application range; because the utility model is additionally provided with a suspended chain, the fluidized bed has better bubble breaking effect.
