Abstract

Disclosed are an internal member and a fluidized bed reactor comprising same. The internal member comprises a first circular baffle plate (11), a second circular baffle plate (12), and at least one third circular baffle plate (13) located between the first circular baffle plate (11) and the second circular baffle plate (12), wherein the first circular baffle plate (11), the second circular baffle plate (12) and the third circular baffle plate (13) are arranged in parallel and at intervals; and at least one first baffle plate (2) and at least one second baffle plate (3), wherein the first baffle plate (2) and the second baffle plate (3) are both arranged between the first circular baffle plate (11) and the second circular baffle plate (12).

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an internal component and a fluidized bed reactor comprising the internal component. Background technique [0002] Due to the good heat and mass transfer properties of fluidized bed reactor, it has been widely used in industry. [0003] The existing fluidized bed reactor mainly has the following problems: [0004] (1) The existence of bubbles will weaken the momentum exchange between gas and solid phases, leading to the generation of "air cushion" and "air festival", resulting in a longer residence time of gas phase and solid phase, and it is difficult to establish a concentration and temperature gradient. [0005] (2) The friction between gas and solid particles is insufficient, and the catalyst utilization rate is low. [0006] (3) The back-mixing of solid particles in the fluidized bed reactor is serious, which reduces the yield of the target product. [0007] Th...
