The principle of the shift reaction is to make CO and H in the process gas under the condition of a certain pressure and temperature and the action of a catalyst 2 O (g) is subjected to conversion reaction to generate H 2 And CO 2 The reaction formula is as follows:
CO+H 2 O＝CO 2 +H 2 +Q；△H＝-41.1kJ/mol；Q＝10861-1.44T-0.4×10-4T 2 +8×18-8T 3 。

in the split system provided by the present utility model, the split system includes a plurality of gasifier units 10, a first connecting line 20, and a plurality of shift converter modules 40, each gasifier unit 10 includes a plurality of gasifiers, and an air outlet of each gasifier is used for discharging raw gas; the first connecting line 20 has a plurality of connecting positions, and a first on-off valve 21 is arranged between two adjacent connecting positions of the first connecting line 20 so as to control on-off between the two adjacent connecting positions at two sides of the first connecting line through the first on-off valve 21; the plurality of gasifier units 10 are arranged in one-to-one correspondence with the plurality of connection positions of the first connection line 20, and the air outlets of the plurality of gasifiers of each gasifier unit 10 are connected and communicated with the corresponding connection positions of the first connection line 20; each shift converter assembly 40 has an air inlet, the air inlet of the shift converter assembly 40 being for the entry of raw gas; the plurality of shift converter modules 40 are disposed in one-to-one correspondence with the plurality of connection positions of the first connection line 20, and the air inlet of each shift converter module 40 is connected to and communicates with the corresponding connection position of the first connection line 20.
As can be seen from the above structure, the plurality of gasification furnace units 10 and the plurality of shift furnace assemblies 40 are arranged in one-to-one correspondence; when all the first on-off valves 21 on the first connecting line 20 are closed, raw gas discharged from a plurality of gasifiers of each gasifiers unit 10 enters the corresponding converter assembly 40 through the gas inlet of the corresponding converter assembly 40; the shunt system of this application is through setting up first connecting line 20 and first on-off valve 21 to when at least one gasifier of one of them gasifier unit 10 jumps suddenly, can be through operating corresponding first on-off valve 21, so that other gasifier units 10 can be to the corresponding converter subassembly 40 of this gasifier unit 10 in let in raw gas, and then avoid because of the raw gas volume in the corresponding converter subassembly 40 suddenly reduces, and the problem of the converter overtemperature of this corresponding converter subassembly 40 that leads to. When the output of the raw gas of one of the gasifier units 10 increases, the corresponding first on-off valve 21 may be operated to make the gasifier unit 10 output the raw gas to the other shift converter assembly 40, so as to avoid or reduce the problem of the shift converter collapse temperature of the corresponding shift converter assembly 40 caused by sudden and large increase of the raw gas input of the corresponding shift converter assembly 40.
Therefore, the diversion system can avoid or reduce the problem that the raw gas entering amount of the corresponding converter assembly 40 suddenly rises or falls due to the increase or decrease of the raw gas output by the gasifier unit 10, so as to cause the converter of the corresponding converter assembly 40 to collapse or over-temperature, i.e. the diversion system of the application cannot cause too large fluctuation of the gas amount of a certain converter assembly 40, and solves the problem that the arrangement mode of the gasifier unit and the converter assembly in the prior art has the risk of over-temperature or collapse of the converter.
