Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Fig. 1 is the schematic cross-section of the embodiment one of the multifunctional nozzle of fixed bed slag gasification furnace of the invention.This reality
Multiple passages are provided with the multifunctional nozzle 1 for applying example；Gasifying agent passage 2 is located at the center of multifunctional nozzle 1 in multiple passages,
Gasifying agent passage 2 is used to spray into the gasifying agent used by fixed bed slag gasification furnace combustion gasification.
As shown in figure 1, in the multifunctional nozzle 1 of the fixed bed slag gasification furnace of the present embodiment, degassifying in multiple passages
During accessory channel 3 outside agent passage 2 is evenly distributed on multifunctional nozzle 1, around gasifying agent passage 2, can so ensure many
The balance of the structure of function nozzle 1 so that structure is more stablized.Embodiment as shown in Figure 1 is with gasifying agent passage 2 weeks
Enclose to be uniformly distributed as a example by seven accessory channels 3 and describe technical scheme.In practical application, the number of accessory channel 3
Set according to the actual requirements, be not herein limited.Multiple accessory channel 3 can also arbitrarily be distributed in gasification according to demand in addition
Around agent passage 2, it must be uniformly distributed not limited in the present invention.
In the multifunctional nozzle 1 of the fixed bed slag gasification furnace of the present embodiment, gasifying agent passage 2 is mainly used in spraying into be fixed
Gasifying agent such as steam or carbon dioxide and oxygen in bed slag gasification furnace required for combustion gasification.
And other accessory channels 3 are used to spray into the waste water of the whole gasification system comprising fixed bed slag gasification furnace
Or dust-laden tar, the recovery and utilization of material are realized, realize the purpose of environmental protection；Fine coal can also be sprayed into, raw gas is improve
Yield；Auxiliary gasifying agent can also be sprayed into, to adjust the composition and ratio of fixed bed slag gasification furnace product.For example work as gasification
Agent be steam oxygen mixture when, it is possible to use carbon dioxide as auxiliary gasifying agent, to lift the ratio of carbon monoxide in raw gas,
The ratio regular meeting of hydrogen of course simultaneously declines；When gasifying agent is carbon dioxide and oxygen mixture, it is possible to use steam is used as auxiliary
Gasifying agent, to lift the ratio of methane and hydrogen.
It should be noted that as needed, the multifunctional nozzle 1 of the fixed bed slag gasification furnace of the present embodiment it is multiple auxiliary
Passage 3 is helped, any identical material can be simultaneously sprayed；Different materials can also respectively be sprayed simultaneously；Certainly also may be used
Same material is sprayed with part, materials different in addition are sprayed in part；Can certainly be partly idle using part.For example it is multiple
Two accessory channels 3 adjacent in accessory channel 3 spray different materials, and respectively the accessory channel 3 of 1 separately can spray
Same material, in this manner it is ensured that the material in the body of heater of penetrating fixed bed slag gasification furnace can be sufficiently mixed uniformly, protects
Demonstrate,prove the material for spraying into and participate in combustion reaction to greatest extent.Or during multiple accessory channels 3 can also be set, position it is relative two
