Abstract
Disclosed is a fluidized bed reactor and a heat removal water pipe and application thereof in acrylonitrile production. The fluidized bed reactor comprises at least a reaction cooling section and a vertical inner component provided in the reaction cooling section. Where, at a cross section transverse and perpendicular to a central axis of the fluidized bed reactor, an area of the cross section of the reaction cooling section is designated as S1 (expressed in a unit of m) and an outer contour circumference of the cross section of the vertical inner component is designated as L1 (expressed in a unit of m), L1/S1=2.0-4.3 m. The fluidized bed reactor can promote the breaking of bubbles as early as possible and effectively limit the growth of the bubbles.
