A double-spherical chamber controllable transfer heat shift reactor and CO reaction method thereof

Abstract

The invention discloses a bispherical-cavity controllable heat-removing shift reactor and a CO reaction method of the bispherical-cavity controllable heat-removing shift reactor. A water inlet pipe is arranged at the bottom of a pressure-bearing shell, a lower ball body is connected with the water inlet pipe, a water-diversion spherical cavity is arranged in the lower ball body, the water inlet pipe is communicated with the water-diversion spherical cavity, a water-collection spherical cavity is arranged in an upper ball body, a water outlet pipe is arranged at the top part of the pressure-bearing shell and is communicated with the water-collection spherical cavity, a plurality of heat exchange tubes are connected between the upper ball body and the lower ball body respectively; and reactor internals, an air distribution chamber, an air channel and a catalyst frame are arranged between the upper ball body and the lower ball body respectively. The maintainer enters the inside of the water-diversion spherical cavity and the water-collection spherical cavity by virtue of the water inlet pipe and the water outlet pipe to check and stop leakage without unloading catalysts, and the defect that the existing single pipe type, top-bottom connected box type, plate type or top-bottom split small-pipe-plate type shift reactor which has a direct byproduct of steam cannot be checked and plugged when the catalyst is not unloaded is overcome.

Description

technical field [0001] The invention relates to a CO shift reactor, in particular to a double-sphere cavity controllable heat shift reactor and a CO reaction method thereof. Background technique [0002] As a widely used reactor in the chemical industry, the CO shift reactor has been improved many times, from the original full axial to full radial, and achieved good results in the resistance of the catalyst bed. , but the catalyst bed is still an adiabatic reaction. The catalyst bed is divided into several beds, and indirect heat exchange or water cooling is adopted between each bed. This kind of indirect heat exchange recovery transformation system has the disadvantages of low thermal energy grade, low recovery efficiency of sensible heat and latent heat, easy overheating of the catalyst, simultaneous transformation and side reactions such as methanation, etc. [0003] The existing single-tube format, upper and lower header type, plate type, upper and lower split small tub...
