Agent wet oxidation process processes；Naphthoquinone method processes；Ammonia circulation washing method processes.Here, for especially by which kind of mode to
One coal gas carries out desulfurization process, and the present invention does not do and limits further.
Optionally, can also include after step S101: gas pressing processes.
In the present embodiment, when the first coal gas is input to coke oven combustion chamber, if the force value of this first coal gas is less than
During pressure needed for coke oven combustion chamber, then need the first coal gas is carried out gas pressing process so that it is force value increases, to meet
Force value needed for coke oven combustion chamber.Certainly, if the force value of the first coal gas is more than or equal to the pressure needed for coke oven combustion chamber
Time, it is not necessary to the first coal gas is carried out gas pressing process, can directly use the first coal gas that coke oven is heated.
In the present embodiment, in recirculating fluidized bed gasification generation device, coal particles carries out gasification reaction product prior to gasifying agent
Soft coal gas, owing to this coal gas will be free from the harmful substances such as tar, therefore, during carrying this coal gas, this stable heat
The coal gas of value will not block the pipeline of coke oven.Coal slag after gasification is discharged by recirculating fluidized bed gasification generation device；Secondly,
The coal gas producing gasification carries out separating at high temperature process, can remove the dust in coal gas, thus obtain purer coal gas.
Again, the coal gas after separating at high temperature is carried out heat exchange process, the heat in these coal gas of high temperature can be absorbed, and by defeated for this heat
Deliver in recirculating fluidized bed gasification generation device, with heating for carrying out the gasifying agent of gasification reaction, thus can be at coal
Before granule and gasifying agent carry out gasification reaction, in advance gasifying agent is heated, such that it is able to shorten vaporization time, improve gas
Change efficiency.Again, the coal gas after heat exchanging carries out cryogenic separation process, it is possible to achieve produce recirculating fluidized bed gasification generation device
Raw coal gas carries out dedusting again, thus obtains the first purer coal gas.Additionally, by the first coal gas is carried out at desulfurization
Reason, effectively to remove the pollutant such as hydrogen sulfide in the first coal gas, thus reduces pollution.Finally, after desulfurization being processed
First coal gas is delivered to coke oven combustion chamber and heats coke oven, it is possible to achieve while to coke oven heating, improve coke oven
The stability run and safety.Meanwhile, by coal gas, coke oven is heated, it is also possible to save operating cost, improve Jiao
The economy of stove heating system.

Wherein, circle fluidized-bed gasification furnace 3021 is connected with standby device for coal 301, is receiving what standby device for coal 301 provided
After coal particles, coal particles is carried out gasification process, i.e. carries out gas with the gasifying agent in circle fluidized-bed gasification furnace 3021
Change reaction, can produce in substantial amounts of coal gas, and this coal gas and will be free from the harmful substances such as tar.By at recirculating fluidized bed gas
The bottom changing stove 3021 arranges deslagging unit, its object is to: sent out by recirculating fluidized bed gasification by the coal slag after gasification reaction
Generating apparatus 302 is discharged, to avoid reusing these coal slags that can not again gasify.Optionally, gasification process includes one
Plant or various ways: air gasification processes；Oxygen-rich gasification processes；Pure oxygen gasification processes.Here, for especially by which kind of mode
Coal gas is carried out gasification process, and the present invention does not do and limits further.
Further, by arranging separating at high temperature unit 3022, and the input port of cryogenic separation unit 3024 and recycle stream
The delivery outlet changing bed gasification furnace 3021 connects, and the coal gas that gasification reaction produces just can be carried out by such cryogenic separation unit 3024
Separating at high temperature processes, and its object is to: the coal gas producing circle fluidized-bed gasification furnace 3021 carries out dedusting so that the coal of generation
Bigger coal particles in gas re-enters in circle fluidized-bed gasification furnace 3021 and gasifies, to improve the conversion effect of coal gas
Rate, it is also possible to the dust removed in coal gas, thus obtain purer coal gas.
Further, by arranging heat exchange unit 3023, and the output of heat exchange unit 3023 and separating at high temperature unit 3022
Mouth connects, and so that the coal gas after separating at high temperature is carried out heat exchange process, its object is to: owing to containing in the coal gas after separating at high temperature
Substantial amounts of heat, by heat exchange unit 3023, can absorb the heat in these coal gas of high temperature, and this heat is delivered to circulation
In fluidized-bed gasification furnace 3021, with heating for carrying out the gasifying agent of gasification reaction, thus can be in coal particles and gasification
Before agent carries out gasification reaction, in advance gasifying agent is heated, such that it is able to shorten vaporization time, improve gasification efficiency.
Further, by arranging cryogenic separation unit 3024, and the input port of cryogenic separation unit 3024 and heat exchange list
Unit 3023 connects, and carries out cryogenic separation process with the coal gas after heat exchanging, its object is to: coal gas of high temperature is through heat exchange unit
After 3023 heat exchange process, the temperature of the coal gas obtained is relatively low, then is carried out low temperature coal gas point by cryogenic separation unit 3024
From process, it is possible to achieve the coal gas producing recirculating fluidized bed gasifier bed carries out dedusting again, thus obtain purer the
One coal gas.Optionally, separating at high temperature processes and cryogenic separation processes and may each comprise one or more modes: at cyclone dust removal
Reason；Bag-type dust processes；Electric precipitation processes；Wet dedusting processes.Here, for which kind of mode to carry out dust removal process by, this
Invention is not particularly limited.
In the present embodiment, circle fluidized-bed gasification furnace 3021 receive coal particles that standby device for coal 301 provides it
After, carry out gasification reaction generation coal gas, and this coal gas will be free from Jiao with the gasifying agent in circle fluidized-bed gasification furnace 3021
The harmful substances such as oil, therefore, during conveying coal gas, this coal gas is not result in line clogging.Again by separating at high temperature list
The coal gas that gasification is produced by unit 3022 carries out separating at high temperature process, can remove the dust in coal gas, thus obtain purer
Coal gas.By heat exchange unit 3023, the coal gas after separating at high temperature is carried out heat exchange process again, these coal gas of high temperature can be absorbed
In heat, and this heat is delivered in circle fluidized-bed gasification furnace 3021, with heating for carrying out the gasification of gasification reaction
Agent, thus can heat gasifying agent before coal particles carries out gasification reaction with gasifying agent in advance, such that it is able to
Shorten vaporization time, improve gasification efficiency.Carried out at cryogenic separation by the coal gas after cryogenic separation unit 3024 heat exchanging again
Reason, it is possible to achieve the coal gas producing circle fluidized-bed gasification furnace 3021 carries out dedusting again, thus obtain purer the
One coal gas.By gas desulfurizer 304, first coal gas is carried out desulfurization process again, effectively to remove the sulfur in the first coal gas
Change the pollutant such as hydrogen, thus reduce pollution.Finally, the first coal gas after desulfurization being processed is delivered to coke oven device 303 and focuses
Stove heats, it is possible to achieve while focusing furnace apparatus 303 heating, improve stability and safety that coke oven runs.
