Problems solved by technology

[0004] The Chinese patent with application number 201510072235.6 applied for "A Double-head Controllable Water Transfer Heat Transfer Reactor". The main problems are as follows: The patent supports the heat exchange tube structure through the partition plate. Since the partition plate is a flat plate structure, its stability is poor , usually by increasing the wall thickness of the plate to improve stability
The increase in plate thickness leads to an increase in equipment investment and increase

Abstract

The invention relates to a radial bed isothermal reactor which comprises a furnace body, a shift gas collecting pipeline and a plurality of heat exchange tubes; the radial bed isothermal reactor is characterized in that an upper tube plate, a middle tube plate and a lower tube plate are sequentially arranged in the furnace body from top to bottom to divide an inner cavity of the furnace body intoan upper cavity, a steam cavity, a reaction cavity and a lower cavity; a catalyst frame is arranged in the reaction cavity; a raw material gas channel is formed in a gap between the side wall of the catalyst frame and the furnace body; through holes are formed in the lower tube plate; each heat exchange tube comprises an outer tube and an inner tube sleeved in the outer tube; the upper end of eachinner tube is limited on the upper tube plate and communicated with the upper cavity, and a lower port of each inner tube is communicated with the inner cavity of the corresponding outer tube; the upper end part and the lower end part of each outer tube are respectively limited on the middle tube plate and the lower tube plate; the furnace body is provided with a cooling water inlet communicatedwith the upper cavity, a steam outlet communicated with the steam cavity, a feed gas inlet and a shift gas outlet communicated with the lower cavity.

Description

technical field [0001] The invention relates to a CO shift reactor, in particular to a radial bed isothermal reactor. Background technique [0002] During the design process of the high-concentration CO shift process produced by pulverized coal gasification in China, adiabatic shift furnaces are often used in shift furnaces. Since the CO content in the crude synthesis gas is high, and the shift reaction is a strong exothermic process, the shift unit adopts multiple adiabatic furnaces in series to remove the reaction heat between the furnaces. This has also caused a series of problems such as the traditional high-concentration CO shift process is complicated, the number of shift furnaces is large, the system pressure drop is large, the equipment investment is high, and the temperature control of the shift furnace is difficult. [0003] The working principle of the isothermal shift furnace is relatively simple. Heat exchange pipes are built into the isothermal shift furnace. ...
