Description
Technical field
The present invention relates to a kind of gasification gas making device of carbonaceous solids material, it is more particularly related to a kind of water
The atmospheric fixed bed slag tap classification gasification reacting furnace of cold wall, belongs to gasification gas making device technical field.
Background technology
Dry ash extraction mode, by taking fixed bed pure oxygen gasification stove as an example, its technological process are adopted existing fixed-bed gasification furnace more
Be to adopt fixed bed gasifier, it is burnt with granule or lump coal is as raw material, the automatic stoker under Jing coal bunkers, self-timing, it is quantitative plus
In entering gasification furnace, with pure oxygen（＞ 99.6%）Make gasifying agent Jing meterings with water vapour and proportion adjustment entered in blending tank and mixed,
By reacting with red-hot charcoal in gas generator after mixing（The endothermic reaction reaches balance with exothermic reaction）, about 900 in stove
Under DEG C hot conditions, each floor area in bed（Core reaction area temperature 1200-1300 DEG C）Enter with feed coal counter current contacting
Row continuous gasification produces water-gas.Unreacted solid slag discharges gasification furnace through lower rotation grate.
Its main chemical reactions formula is as follows：
C+O2=CO2+ Q
2C+O2=2CO+Q
C+CO2=2CO-Q
C+2H2O（Vapour）=CO2+2H2- Q
C+H2O（Vapour）=CO+H2- Q
But this fixed bed solid slag discharging gasifying furnace has that gasification temperature is low, fuel conversion is low and synthesis gas tar content is big
The shortcomings of.
Slag tap gasification furnace is the further development of conventional solid-state deslagging gasification furnace.It is characterized in gasification temperature height, gas
Lime-ash flows out in molten state thus the thermal efficiency of gasification furnace is improved with the production capacity of single stove after change.It is ripe both at home and abroad at present
Feasible fixed bed slag tap gasification technology is BGL crushed coal pressure gasifying technologies, and the gasification process vapor pressure is 2.0-
4.0MPa, gasification furnace top is provided with cloth coal agitator, gasifying agent（Water vapour and oxygen）Sprayed into by gasification furnace bottom nozzle and gasified
Room, lime-ash is discharged at a temperature of higher than coal ash fusion temperature into molten state, and slag flows into Quench quickly through gasification furnace bottom slag notch
Room, here forms solid slag by water Quench, is then discharged by ash lock.It combine the high rate of gasification of slag gasification technology,
The advantage of the high intensity of gasification consumes the cheap advantage of low, furnace binding with fixed bed pressurization/atmospheric gasification technology oxygen.
The molten slag that BGL slag gasification furnace burner hearths gasification, and combustion is produced is stored in gasification furnace bottom dross pond, is passed through
The liquid slag that a large amount of gas supportings that the burning of annular burner the inside is produced are stayed inside cinder notch, as slag increases, when liquid level is arrived
During 1.5 meters or so of certain liquid level, gasification furnace pressure and the general 48KPa of short circuit pressure reduction excite program automatic discharge, under starting every time
Pressure leak process is fast during slag, and pressure release is completed in 2s, and pressure reduction drops to 18kPa from 49kPa.Slag after Quench, cooling it is final from
Discharge in pressure system.
Above-mentioned technology Publication No. CN104327881A as disclosed in State Intellectual Property Office is in 2015.02.04, it is entitled
The invention of " a kind of liquid continuous discharging slag fixed-bed gasification furnace and its gasification process ", a kind of liquid continuous discharging slag that the invention is related to
Fixed-bed gasification furnace and its gasification process, it is characterised in that：It from top to bottom successively include a raw material cabin, a raw material lock hopper, one

Portion；Slag-discharging device is installed in the body of heater below furnace lining, and body of heater lower end is fastenedly connected with slag shock chamber upper end, under slag shock chamber
End is fastenedly connected with slag lock upper end.The gasifying agent nozzle of the present invention employs the single-pass configuration for only conveying gasifying agent, improves
The service life of gasifying agent nozzle.Overflow-type deslagging pond is effectively ensured smooth deslagging, improves the fortune of fixed bed slag gasification furnace
Line efficiency.
However, it is exactly slag mouth molten slag liquid level and deslagging that BGL slag gasification furnaces are most rambunctious, if control is not
It is good, lower cinder notch will be blocked, liquid level is raised, will plug nozzle there is clarinet phenomenon, cause to stop.If slag pressure release and row
The slag time is oversize, then cinder notch is easily blocked in the precipitation of iron and cooling.If slag frequency is too high, pressure reduction, and time can be affected
Being spaced in too short slag bath may have part lime-ash not to be completely melt, easily stick on slag passage during slag.
Secondly BGL gasification technologies are to introduce domestic in recent years, and industrialization operating experience is few compared with fixed bed, while there is technology
Transfer fee, its proprietary core component（Such as slag bath, nozzle, copper cooling wall）Also external import is required to, also causes it to invest into
This higher, construction period is longer.Compare solid slag discharging gasifying furnace, the slag tap technique of BGL gasification furnaces is arranged, operating process and
Control system is relative complex.
