Charcoal high efficiency, low emission and economy three major issues during trans-utilization.Fluidized gasification is that one kind being capable of clean utilization
The technology of coal resources, has and makees raw material using fine coal and low-grade coal, compared with fixed bed gasification, intensity of gasification height,
The advantages that equipment for gasification is small, and cleaning system is simple.But the furnace apparatus of fluidized gasification both at home and abroad, which exists, at present needs interval parking to replace
Baker burner, be separately provided the stove that goes into operation, the problems such as equipment manufacturing cost is higher, and in baker, can be by fire resisting scuff-resistant coating liner
Material temperature rise and the thermal stress limitation that can be undertaken.Therefore exploitation long-term operation, economy are stronger, meet maximization modern times coalification
The Novel gasification technology that work industry development needs becomes one of emphasis of current fluidized gasification technical research.
The content of the invention
Go into operation heating and ash discharge integrated apparatus and method it is an object of the invention to provide a kind of fluidized-bed gasification furnace.
To reach above-mentioned purpose, the inventive system comprises the reactor that blow valve port is offered including lower end, in reactor
Side wall on offer successively from top to bottom plus sand mouth, coal filling hole and ash discharging hole, ash discharge pipe nipple is installed on the ash discharging hole,
It is also associated with the baker burner with entrance on ash discharge pipe nipple, the baker burner is by its entrance 9 by air and natural gas
Inject in baker burner.
Fluidized-bed gasification furnace of the present invention goes into operation heating and ash discharge integral method, comprises the following steps：
1) sand is added：First, by adding sand mouth to add quartz sand into reactor, then it is passed through from reactor bottom blow valve port
Nitrogen, it is ensured that quartz sand is fluidized with the fluidizing velocity of 0.3m/s in reactor, and the pressure control of simultaneous reactions device exists
0.3MPa~0.31MPa；
2) baker process：First air is entered in baker burner by entrance, then natural gas is entered by entrance and is dried
Burn in stove burner with air contact；Control the ratio of natural gas and air, it is ensured that reactor with the heating rate of 25 DEG C/h into
Row baker；
3) coal process：When the temperature of reactor reaches 600 DEG C, fine coal is added in reactor by coal filling hole, stream
Change speed and 1m/s is gradually promoted to by 0.3m/s, gradually decrease the gas discharge being passed through in baker burner, while pass through reaction
Furnace bottom blow valve port introduces air, is reacted with fine coal, and gas discharge, increase coal amount are gradually decreased according to technological requirement
And air mass flow, when ensureing that the temperature of reactor continues to rise to 800 DEG C, stop the input of natural gas, control adds coal amount
With AIR Proportional, temperature of reactor is set to continue to be increased to 1100 DEG C；
4) ash discharge process：When the material in reactor reaches technological requirement, reactor starts ash discharge, passes through ash discharge pipe nipple
Lime-ash in reactor is discharged, baker is realized and ash discharge is integrated couples.
The integrated apparatus that the present invention is connected after being combined by ash discharge pipe nipple and baker burner with reactor.In baker rank
Section, ash discharge pipe nipple are used as the stove that goes into operation, the baker work of finishing device；In normal course of operation, and ash discharge can be passed through
Mouth reaches the ash discharge function of device, so as to reach gasifier to start working heating and the coupling of ash discharge integrated technique, reduces equipment
Perforate so that device structure is compact, simple, effective to save equipment investment expense, improves its economy.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the present invention includes the reactor 1 that lower end offers blow valve port 3,5, from upper on the side wall of reactor 1
Offered successively under and and add sand mouth 2, coal filling hole 8 and ash discharging hole 7, ash discharge pipe nipple 6 is installed on the ash discharging hole 7, ash discharge is short
It is also associated with the baker burner 4 with entrance 9 on section 6, the baker burner 4 is by its entrance 9 by air and natural gas filling
Enter in baker burner 4.
The fluidized-bed gasification furnace heating that goes into operation of the present invention comprises the following steps with ash discharge integral method：
1) sand is added：First, by adding sand mouth 2 to add quartz sand into reactor 1, then from 1 bottom purge mouth of reactor
3rd, 5 it is passed through nitrogen, it is ensured that quartz sand is fluidized with the fluidizing velocity of 0.3m/s in reactor 1, the pressure control of simultaneous reactions device 1
System is in 0.3MPa~0.31MPa；
2) baker process：First air is entered in baker burner 4 by entrance 9, then by natural gas by entrance 9 into
Enter in baker burner 4 and burn with air contact；Control the ratio of natural gas and air, it is ensured that reactor is with the heating of 25 DEG C/h
