CO+H
2O (vapour)=CO
2+ H
2+ Q
Wherein, Q is a reaction heat, and above initial reaction stage is very violent, and the reaction motive force is very big, and reaction speed is fast, the extremely difficult control of reaction temperature, and when especially water/air ratio was higher, catalyst is overtemperature more easily.When high CO and high temperature (>=400 ℃), also can follow and fly off reaction, the namely for methane reaction:
Flying off reaction can make anxious the increasing of temperature cause sintering of catalyst at short notice.For avoiding high temperature, the measure of taking is with one section catalyst layering filling so that the gas short circuit when temperature raises aggravation, is mended steam again, even mended high pressure nitrogen in design for existing converting means, and the CO in the dilution component is to relax reaction.Even adopt above measure, (when loading as 25%～50%) also is difficult to control not overtemperature of catalyst when the converting means load is low.
Summary of the invention
The technical problem that the utility model will solve provides a kind of reasonable, safe and reliable to operation, good in economic efficiency high CO gas reaction device of compact conformation that can shift out CO reaction heat, control reaction temperature effectively, in time.
In order to solve the problems of the technologies described above; The technical scheme of the utility model provides the high CO gas reaction device of a kind of inner heat exchange type temperature swing type; It is characterized in that: comprise that top and bottom are respectively equipped with the pressure vessel reactor shell of material inlet and material outlet; Pressure vessel reactor enclosure upper end is located in the catalyst adiabatic section; Inside is provided with the multiple group type reaction tube of pipe inner catalyst and is located between the upper perforated plate and lower perforated plate of below, catalyst adiabatic section, and multiple group type reaction tube upper/lower terminal connects upper header and lower collecting box respectively; Water circulating pump one end is connected with upper header through drum, and the water circulating pump other end connects lower collecting box; Pressure vessel reactor enclosure base plate is provided with porous plate, and porous plate is equipped with the sial ball up and down.
Preferably, said water circulating pump is the frequency conversion type feed pump.
When the high CO gas reaction device of a kind of inner heat exchange type temperature swing type that the utility model provides is worked; The pressure vessel reactor, drum, water circulating pump and the multiple group type reaction tube that have the catalyst adiabatic section constitute the byproduct steam system of a forced circulation, and reaction heat is converted into middle pressure steam.Be water between the tubular structure pipe, adopt the frequency conversion type feed pump, forced convertion; Variation according to load changes the water yield in good time, can shift out the CO reaction heat effectively, in time, and the control reaction temperature is in 400 ℃; Keep the reaction speed of CO conversion simultaneously, practiced thrift catalyst amount.Especially under underload, make reaction temperature control simple, be prone to row effectively.
The device that the utility model provides has overcome the deficiency of prior art; Through pressure vessel reactor and the frequency conversion type feed pump that has the catalyst adiabatic section; Can shift out the CO reaction heat effectively, in time; The control reaction temperature, the save catalyst consumption, and have compact and reasonable, safe and reliable to operation, good in economic efficiency characteristics.
