Description

technical field [0001] The invention relates to the field of energy and chemical industry, in particular to a dense-phase fluidization reaction control device and method. Background technique [0002] The phenomenon that a solid reaction medium exhibits a flow property similar to that of a fluid under the action of a fluid is called fluidization. Based on the different fluid flow rates, the fluidized bed has different bed densities, and the reaction that occurs in this fluidized bed is called a fluidized reaction. In the field of modern energy and chemical industry, the dense-phase fluidized bed can provide the reaction medium with ultra-high mass and heat transfer rate, cycle rate and contact area, which is very beneficial to the gas-solid two-phase flow reaction. The ideal fluidized reaction bed behavior is stable and controllable, but in the actual operation process, due to the flow velocity disturbance on the flow section, the violent impact and entrainment effect of th...
