Heat exchange medium uniform distribution device of U-shaped pipe organic silicon fluidized bed reactor

Abstract

A heat exchange medium uniform distribution device of a U-shaped pipe organic silicon fluidized bed reactor comprises a jacket pre-distributor and a plurality of heat exchange assemblies, and each heat exchange assembly comprises a heat exchange medium inlet branch pipe, a heat exchange medium outlet branch pipe and a plurality of groups of U-shaped heat exchange pipes; an inlet and an outlet of each group of U-shaped heat exchange pipes are respectively communicated with the heat exchange medium inlet branch pipe and the heat exchange medium outlet branch pipe; the jacket pre-distributor comprises an inlet distribution section and an outlet distribution section, the inlet distribution section is respectively communicated with the heat exchange medium inlet and the heat exchange medium inlet branch pipe, and the outlet distribution section is respectively communicated with the heat exchange medium outlet and the heat exchange medium outlet branch pipe. A heat exchange medium can be uniformly distributed, and the stability and balance of temperature distribution in a fluidized bed are ensured; the structure is reasonable, the working performance is stable, equipment and pipeline arrangement and maintenance are convenient, and operation and use are safe.

Description

technical field [0001] The invention belongs to the field of chemical reaction equipment and relates to performance improvement of a heat exchange structure, in particular to a heat exchange medium uniform distribution device for a U-shaped tube organosilicon fluidized bed reactor. Background technique [0002] A fluidized bed is a device that relies on the flow of gas or liquid to drive solid particles to move like a fluid and reacts between the particles and the fluid at the same time. It has a series of advantages such as high heat transfer, mass transfer and chemical reaction rate, large operation flexibility, large production capacity, simple structure and compactness. Especially due to the agitation of bubbles and the fast flow of particles, the heat transfer coefficient between the bed and the inner immersion heat exchange surface is high, which is extremely beneficial to the heat exchange of strong heat exchange reactions. [0003] During the synthesis of organosili...
