Description
Technical field
The utility model is related to a kind of gasification gas making device of carbonaceous solids material, and more specifically, the utility model is related to
And a kind of atmospheric fixed bed slag tap classification gasification reacting furnace of water-cooling wall, belong 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 used existing fixed-bed gasification furnace more
It is burnt or lump coal is raw material using granule to use fixed bed gasifier, through the automatic stoker under coal bunker, self-timing, it is quantitative plus
Enter in gasification furnace, with pure oxygen（＞ 99.6%）Make gasifying agent through metering and proportion adjustment into mixing in blending tank with water vapour,
By being reacted in gas generator with red-hot charcoal after mixing（The endothermic reaction reaches balance with exothermic reaction）, about 900 in stove
Under DEG C hot conditions, by each floor area in bed（1200-1300 DEG C of core reaction area temperature）Enter with feed coal counter current contacting
Row continuous gasification produces water-gas.Unreacted solid slag discharges gasification furnace by 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 contains
The shortcomings of measuring big.
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 thus made the production capacity of the thermal efficiency and single stove of gasification furnace to improve in molten state 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 and gasified by gasification furnace bottom nozzle
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, forms solid slag by water Quench herein, 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 burning is produced inside annular burner 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 difference excite program automatic discharge, under starting every time
Pressure leak process is fast during slag, and pressure release is completed in 2s, and pressure difference drops to 18kPa from 49kPa.Slag after Quench, cooling it is final from
Discharged in pressure system.
Above-mentioned technology Publication No. CN104327881A as disclosed in State Intellectual Property Office 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 includes a raw material cabin, a raw material lock hopper, one successively

Bottom is simultaneously arranged circumferentially along body of heater, and the outlet of each gasifying agent nozzle is stretched into body of heater behind body of heater furnace wall and furnace lining
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.Smooth deslagging is effectively ensured in overflow-type deslagging pond, improves the fortune of fixed bed slag gasification furnace
Line efficiency.
However, it is exactly slag mouthful molten slag liquid level and deslagging that BGL slag gasification furnaces are most rambunctious, if control is not
It is good, will block lower cinder notch, liquid level rise, will plug nozzle there is clarinet phenomenon, cause parking.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 difference, and time can be influenceed
Being spaced in too short slag bath may have part lime-ash not to be completely melt, easily be sticked 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.Compared to solid slag discharging gasifying furnace, the slag tap technique of BGL gasification furnaces is set, operating process and
Control system is relative complex.
