Multitubular gasification reactor

Abstract

The invention relates to a multitubular gasification reactor. The multitubular gasification reactor is characterized by comprising an interception section, a reaction section and a gasification mixing section which are sequentially connected from top to bottom, wherein the interception section comprises a first sleeve; flanges are arranged at two ends of the first sleeve; a blind plate is connected with the flange at top end of the first sleeve; a liner with U-shaped longitudinal section is arranged inside the first sleeve; the top opening of the liner is connected with the bottom part of the blind plate in a sealing manner; a freeing pipe and an admission pipe connected with the liner are arranged on the blind plate; and air outlets are formed in two opposite side walls of the first sleeve. The multitubular gasification reactor is simple in structure; a novel catalytic reaction device for the gas and the solid is provided and an application scope of the gasification reactor is expanded.

Description

technical field [0001] The invention relates to a tube-and-tube gasification reactor, in particular to a reactor for chemical reaction of gas and solid (boiling point lower than 700°C), belonging to the technical field of chemical equipment. Background technique [0002] As we all know, industrially, gasification reactors and tubular fixed-bed reactors are well-known reactors, and are widely used in chemical production processes. Among them, the gasification reactor is usually used in the process of gasifying carbon-containing raw materials (including coal, organic hydrocarbons, biomass and other carbon-containing substances) to produce synthesis gas. The process is about half a century old, and gasification reactors have been improved and changed over time. At present, a large number of such reactor devices are known, for example, International Shell Co., Ltd., ThyssenKrupp Uhde, Sanzhaopu Fuel Company, Canrek Co., Ltd., East China University of Science and Technology, Chi...

AI Technical Summary

Problems solved by technology

In the vertical direction of the shell and tube fixed bed reactor, there is generally a heat carrier inlet and outlet. Because the reactor shell and the heat carrier inlet and outlet pipes are heated unevenly, and the temperature of the heat carrier is very high during operation, it will cause the shell and the heat carrier to The welding seam of the heat carrier inlet and outlet pipes is under great pressure, which may affect the stable operation of the entire reactor
