A kind of internal component, fluidized bed reactor and application method

Abstract

The invention provides an internal component, a fluidized bed reactor containing the internal component and an application method thereof. The fluidized bed reactor is divided into at least two reaction spaces connected in series up and down through the baffle plate in the internal component. The baffle plate Each of the channels communicates with two reaction spaces adjacent to the inner member. When the air bubbles carrying particles in the first reaction space adjacent to the internal component enter the component pores, the pores crush and break the bubbles, so that the gas after the bubbles break evenly enters the second reaction space adjacent to the internal components, and the air bubbles are carried Most of the catalyst particles settle back into the first reaction space. Because the internal member can not only effectively break the bubbles during work, thereby enhancing the contact effect between the gas-solid two phases, but also allows the gas in the first reaction space to directly enter the second reaction space, effectively preventing the catalyst in the first reaction space from The particles enter the second reaction space to separate the gas-solid phase, thereby effectively inhibiting the gas-solid back-mixing.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an internal component, a fluidized bed reactor and an application method. Background technique [0002] The fluidized bed is a state of fluid-solid contact, that is, a large number of solid particles are suspended in the moving fluid, so that the solid particles have some apparent characteristics of the fluid. Due to the good heat and mass transfer properties of fluidized bed, it has been widely used in industry. However, due to the existence of air bubbles, the solid particles and air bubbles in the fluidized bed reactor are violently stirred and mixed, resulting in a longer residence time of the gas phase and solid phase, and it is not easy to establish a concentration and temperature gradient. At the same time, air bubbles will cause serious back-mixing of solid particles, reducing the yield of the target product. [0003] In order to break up the bubbles and supp...

Problems solved by technology

However, the internal component is also too complex, which limits its industrial application, and cannot effectively suppress the gas-solid back-mixing.
