Novel industrial fluidized bed reactor adopting inorganic thermal superconducting technology

Abstract

The invention discloses a novel industrial fluidized bed reactor adopting the inorganic thermal superconducting technology.The novel industrial fluidized bed reactor comprises a barrel body and one or more inorganic thermal superconducting pipes arranged in the barrel body; the barrel body is separated into a thermal insulation area, a heat exchange area and a reaction area from top to bottom through an upper partition plate and a lower partition plate; each inorganic thermal superconducting pipe is internally provided with a casing pipe, a cavity between each casing pipe and the corresponding inorganic thermal superconducting pipe is filled with an inorganic thermal superconducting working medium, each internally-arranged casing pipe comprises an internally-arranged electrical heating pipe on the lower portion and a lead-out wire protective pipe on the upper portion, and the two ends of each inorganic thermal superconducting pipe extend into the thermal insulation area and the reaction area respectively.By means of the novel industrial fluidized bed reactor, the structural form of an existing industrial fluidized bed is changed completely, and the novel industrial fluidized bed reactor had the advantages that a cold medium (or a heat medium) is isolated from the reaction area, heating and heat obtaining are integrated, the structure is simple, maintenance is convenient to conduct, heat transfer efficiency is high, temperature uniformity inside a bed is good, operation safety is high, and the applicable temperature range is wide.

Description

technical field [0001] The invention relates to a novel industrial fluidized bed reactor for inorganic thermal superconducting technology. Background technique [0002] The fluidized bed reactor is a reactor that uses gas or liquid to pass through the granular solid layer to keep the solid particles in a state of suspension and movement, and to perform a gas-solid phase reaction process or a liquid-solid phase reaction process. When used in a gas-solid system, it is also called an ebullated bed reactor. The early application of fluidized bed reactors in modern industry was the Winkler furnace for pulverized coal gasification in the 1920s; but the development of modern fluidized reaction technology was represented by petroleum catalytic cracking in the 1940s. At present, fluidized bed reactors have been widely used in chemical industry, petroleum, metallurgy, nuclear industry and other departments. [0003] The solid particles in the fluidized bed move like a fluid. Due to ...
