To.Coal gasification reaction both can be carried out at ambient pressure, can carry out under an increased pressure again,
Pressurized gasification technology is the second filial generation bed pulverized coal gasification technology grown up in normal pressure technical foundation,
Owing to it is single, stove production capacity is big, gasification efficiency is high, highlight excellent than coal consumption and etc. more relatively low than oxygen consumption
Point, becomes the first-selection of large-scale Coal Gasification Technology, and is widely used in large-scale Coal Chemical Industry and IGCC
In power generation project.But the most enterprises in the industries such as metallurgy, building materials, machinery it is generally required to
Bunker coal tolerance is relatively fewer, and need not coal gas and have the highest pressure, at the same time it is wished that gas station
Investment relatively small, so, investing relatively low atmospheric gasification technology becomes its first-selected skill
Art.
The most typical atmospheric gasification technology has one-part form fixed-bed gasification furnace, two-period form fixed bed
Gasification furnace and K-T stove.Fixed-bed gasification furnace have coal adaptability stove production capacity poor, single little,
Coal gas has the shortcomings such as hydro carbons, tar and phenol etc., environmental problem are many, is the gasification technology fallen behind.
K-T stove is a kind of normal pressure entrained flow bed gasification technology, and gasification temperature is high, environmental friendliness, but by
Being affected by size in atmospheric pressure device, pulverized coal particle is not enough at gasification residing time in furnace, and carbon converts
Rate is low, and unburned carbon in flue dust is high.
Summary of the invention
Low for the efficiency of carbon con version having the existence of atmospheric gas fluidized gas producer at present, unburned carbon in flue dust
Height, the shortcoming that unit style gas energy consumption is high, the purpose of this utility model is to provide a kind of production and synthesizes
The device of gas, has efficiency of carbon con version height, slagging rate height, gasification efficiency height, investment and engineering and makes
The feature that valency is low.
In order to achieve the above object, this utility model adopts the following technical scheme that
A kind of device producing synthesis gas, including coal pulverizer 1, coal pulverizer 1 discharge often connects
Press-powder storehouse 2 entrance, normal pressure powder cabin 2 exports and connects gasification furnace 5 by coal dust burner 4, at normal pressure powder
It is communicated with conveying gas piping on the pipeline that storehouse 2 connects with gasification furnace 5 and is provided with coal dust pump 3,
The reaction zone outlet layout of gasification furnace 5 catches slag equipment 13, the lower cinder notch connection slag ladle 8 of gasification furnace 5,
Syngas outlet connection waste heat boiler 9 entrance of gasification furnace 5, waste heat boiler 9 outlet dry method
Cleaner unit 10 entrance, nonaqueous dust cleaner 10 synthesizer outlet synthesis gas downstream user, dry method
The outlet of cleaner unit 10 flying dust is sequentially communicated ash lock hopper 11, flying dust storage tank 12 and fly ash reinjection pipeline
14, fly ash reinjection pipeline 14 outlet connects normal pressure powder cabin 2 entrance.
Conveying gas in described conveying gas piping is nitrogen, carbon dioxide or air.
Described gasification furnace 5 is atmospheric gas fluidized gas producer, uses slag tap method, gasification temperature
Degree is higher than ash fusion point.
It is provided with screw feeder after described coal dust pump 3.
The raw material of described gasification furnace 5 is dry pulverized coal, or carbon containing and the solid material of hydrogen；Gasification furnace 5
Gasifying agent be pure oxygen and steam or oxygen-enriched.
Compared with prior art, innovative point of the present utility model is:
1) utilize fly ash reinjection pipeline, high carbon containing flying dust is back in gasification furnace, again
Gasification, reclaim flying marking heat, produce more synthesis gas, improve gasification efficiency and
Total efficiency of carbon con version, reduces unit coal consumption.
2) efficiency of carbon con version and the restriction of time of staying requirement, gas are breached due to gasification furnace design
Change stove size and dimension can retrofit, thus reduce cost.Constant-pressure and high-temperature coal gas is at waste heat boiler
Interior being lowered the temperature, normal pressure gas waste heat boiler is more easy to design, and cost is low.
3) gasification furnace top is arranged and is caught slag equipment, gasification furnace retention efficiency is high, it is to avoid flying dust is again
After circulation comes into operation, cleaner unit load is excessive, and equipment manufacturing cost is high, the problem of fluctuation of service.
4) using normal pressure pulverized coal warehouse and coal dust pump, flying dust is recycled to pulverized coal warehouse, coal dust and
Fly ash carry is simple, and induction system cost is low.
