Abstract

The invention discloses an up-flow reaction regeneration fluidization system with multiple reactors connected in series. A down-flow plug valve comprises an electric mechanism 31, a transmission mechanism 32, a valve seat 33, an adjusting sleeve 34, sealing rings 351 and 352, a valve rod sleeve 36, a valve rod 37, a valve head 38 and a valve body 39; the valve rod 37 is vertically arranged and isfree from flexibility deformation; and solid particles flow out obliquely downwards from an inclination part of the lower part of the valve body 39, so that abrasion to the plug valve is low. The up-flow reaction regeneration fluidization system with the multiple reactors connected in series comprises a reactor 1 and a reproducer 2; the down-flow plug valve is arranged on a reactor catalyst discharging pipe 16; by adopting the up-flow reaction regeneration fluidization system with the multiple reactors connected in series, uniform upward air streams can be provided for granular raw materials;the fluidization reaction system is easy for material inlet and outlet; and solid particles can be uniformly and effectively fluidized in the device.

Description

technical field [0001] The invention belongs to the fields of petroleum and chemical industry, and in particular relates to a downflow plug valve of a fluidized upflow multi-reactor series connection and regeneration process and an upflow reaction regeneration fluidization system in which a plurality of reactors are connected in series. Background technique [0002] Fluidization refers to the use of the effect of flowing fluid to drive the solid particle group in a suspended state, so that the solid particle has some apparent characteristics of the fluid, and the full contact between the fluid and the solid particle is used to facilitate the uniformity of the reaction ,full. In the field of chemical industry, the fluidized reactor device manufactured by using this principle can make solid particles and fluid, such as reaction gas, contact uniformly and fully in a flowing state, and improve the reaction efficiency. [0003] The fluidized reactor device is a reactor that uses...
