Embodiment 1
Please refer to Fig.1-Fig. 3, gasification furnace 30 provided in this embodiment comprising the inside of furnace body 2, furnace body 2 has burning
Storehouse 3, cleaning position 15 and fire-retardant storehouse 12.Cleaning position 15 and fire-retardant storehouse 12 are located at the top of combustion bin 3, and setting is useful in fire-retardant storehouse 12
In the flame-retardant device 10 that Mars resistance is gone out.
It is isolated by first partition 25 between cleaning position 15 and fire-retardant storehouse 12 and combustion bin 3, fire-retardant storehouse 12 and cleaning position 15
Between be isolated by second partition 26.Flame-retardant device 10 is mounted on a side surface of the first partition 25 close to fire-retardant storehouse 12.
Mutually isolated independence between combustion bin 3, cleaning position 15 and 12 3, fire-retardant storehouse warehouse, the gas between three warehouses
Flame-retardant device 10 is circulated through to realize.It is specific as follows.
The input terminal of flame-retardant device 10 is equipped with air inlet pipe 7, and the air inlet port of air inlet pipe 7 passes through fire-retardant storehouse 12 and combustion bin 3
Between first partition 25 and extend to the inside of combustion bin 3.The gas that combustion bin 3 generates can enter air inlet pipe 7.
The output end of flame-retardant device 10 is equipped with escape pipe 11, and the air outlet of escape pipe 11 passes through fire-retardant storehouse 12 and cleaning position
Second partition 26 between 15 and the inside for extending to cleaning position 15.Gas from combustion bin 3 by flame-retardant device 10 processing after,
Go out from escape pipe 11, then is flowed into cleaning position 15.
The top of cleaning position 15 is equipped with exhaust pipe 13, and the air inlet port of exhaust pipe 13 passes through roof and the extension of furnace body 2
To cleaning position 15, the exhaust port of exhaust pipe 13 is located at the outside of furnace body 2.
Gas is flowed out to outside furnace body 2 by exhaust pipe 13 after escape pipe 11 comes out, is collected or is discharged.
In the process of circulation of entire gas, flame-retardant device 10 is being passed in the gas with Mars that combustion bin 3 generates
In, it is gone out and is eliminated by timely resistance, no longer carry fire after being flowed out in escape pipe 11 through treated the gas of flame-retardant device 10 in this way
Star avoids Mars to damaging and disappearing caused by follow-up equipment (such as the filter screen 14 being arranged in cleaning position 15) in this way
The fire hazard brought in addition to Mars, moreover it is possible to prevent Mars to be blown into outside air, prevent security risk from the root cause, carry
The high safety of whole equipment.
Certainly, the structure inside flame-retardant device 10 can there are many, as long as in the gas that can in time generate combustion bin 3
Mars resistance, which is gone out, to be belonged to the scope of protection of the present invention.
It please refers to Fig.3 and Fig. 4, in the present embodiment, the inside of flame-retardant device 10 has back-fire relief chamber 24, the middle part of back-fire relief chamber 24
Multiple fire-retardant cores 27 that Mars resistance can be gone out are installed, multiple fire-retardant cores 27 are evenly distributed along same axis.It is also understood that
Multiple back-fire reliefs are evenly distributed along air-flow direction of advance.Such arrangement mode can utmostly ground resistance go out the Mars in air-flow.
Compared to single 27 design structure of fire-retardant core, the fire-retardant core 27 in multiple fire-retardant cores 27 rearward can be by forward fire-retardant core 27
That omits is not gone out by Mars that resistance is gone out and then secondary resistance, is avoided as much as Mars omission, and the resistance for improving Mars is gone out efficiency, in turn
Improve safety.
In the present embodiment, fire-retardant core 27, can (such as Beijing scape period of the day from 7 a. m. to 9 a.m. be for stone buying on the market as existing structure
Change the ZHB types fire-retardant core of equipment Co., Ltd production).
Certainly, in other embodiments, 27 structure of fire-retardant core using non-existing design is also to fall into the protection of the present invention
Range.Namely say no matter use 27 structure of fire-retardant core of which kind of design, Mars is eliminated, is hindered and is gone out, filters as long as it has
Function or similar functions, that is, fall into protection scope of the present invention.
In the present embodiment, fire-retardant core 27 is set as two, is the first fire-retardant core 22 and the second fire-retardant core 23, two resistances respectively
The axis of fiery core 27 overlaps.Two fire-retardant cores 27 are mounted on along air-flow direction of advance in back-fire relief chamber 24.Certainly, implement in others
In example, the quantity of fire-retardant core 27 can be 3,4,5,6 etc. it is multiple.No matter how many a fire-retardant cores 27 are set, either
As long as multiple fire-retardant cores 27 are belonged to the scope of protection of the present invention along air-flow direction of advance arranged in series.
Further, in the present embodiment, along fire-retardant core 27, toward on the direction of air inlet pipe 7, the radial direction of back-fire relief chamber 24 is cut
The diameter in face successively decreases.It is to be understood that back-fire relief chamber 24 is located at left side (direction is for Fig. 1) structure of fire-retardant core 27 in cone
Shape designs.
The conical design of the part is slot close to one end of air inlet pipe 7, is wide opening close to one end of fire-retardant core 27.The cone
Shape can be designed so that when gas enters back-fire relief chamber 24, air velocity reduces, and cushioning effect is played to air-flow.Improve air-flow
Residence time in back-fire relief chamber 24 or anelasticity keep the time that fire-retardant core 27 contacts gas elongated or throughput is more, in turn
Hinder more Mars that go out.In addition, gas velocity reduces, the impact force to fire-retardant core 27 can be slowed down, prevent fire-retardant core 27 along gas
Stream direction is subjected to displacement, and improves the stability of fire-retardant core 27.
Further, in the present embodiment, along fire-retardant core 27, toward on the direction of escape pipe 11, the radial direction of back-fire relief chamber 24 is cut
The diameter in face successively decreases.It is to be understood that back-fire relief chamber 24 is located at right side (direction is for Fig. 1) structure of fire-retardant core 27 in cone
Shape designs.
The conical design of the part is slot close to one end of escape pipe 11, is wide opening close to one end of fire-retardant core 27.It should
Partial conical design structure can prevent fire-retardant core 27 from for example being turned right displacement by lateral displacement occurs when gas shock,
And then improve the stability of fire-retardant core 27
Further, in the present embodiment, furnace body 2 is internally provided with water trapping layer 6, and water trapping layer 6 is located at the outer of combustion bin 3
Side and the outside for covering combustion bin 3.
Existing coal chemical industry gasification furnace 30 is the outside by the way that heat supply water pipe to be mounted on to combustion chamber mostly when in use,
The heat generated using coal dust firing heats the water inside heat supply water pipe, and the heat to be generated to coal burning carries out profit
With however, the contact area of heat supply water pipe and combustion chamber is smaller so that the heat generated in process of coal combustion is largely lost,
Cause energy waste, the energy utilization rate of device relatively low.
In the present embodiment, water trapping layer 6 is set to the inside of furnace body 2, the outside of combustion bin 3 will be covered, greatly increased
The contact area of water and combustion bin 3 so that the heat of coal dust firing generation can directly be absorbed by being flowed into the water inside folder sump
Amount reduces heat losses, effectively increases the energy utilization rate of whole equipment.
