Description
Technical field
The present invention relates to a kind of coal raw materials being used in tamping coke furnace, and in particular to it is a kind of using it is existing make firm by ramming stove carry out it is low
The coal raw material of rank coal upgrading belongs to low-order coal upgrading transformation technology field.
Background technology
Coal is the main energy sources in China, and 70% is accounted for about in primary energy structure.During very long geological changes,
The formation of coal is acted on by many factors, causes categories of coal various.According to the difference of structure and composition, coal is divided into brown
3 major class of coal, bituminous coal and anthracite, metabituminous coal is divided into as lower-grade metamorphic bituminous and mesometamorphism bituminous coal, lower-grade metamorphic bituminous to be called time cigarette
Coal is referred to as " low-order coal " together with lignite.Low-order coal is the product at incoalation initial stage, with phosphorus content is low, moisture is high, easy
The characteristics of dusting, easy spontaneous combustion, fugitive constituent height, immersion intensity difference, anti-dropping intensity difference, these characteristics are limited to the direct of low-order coal
It develops and uses, but according to statistics, China's low order coal reserves accounts for the whole nation and has verified 55% of coal reserves or more, up to 561,200,000,000 tons, this nothing
It doubts and causes a kind of waste of resource.And with domestic energy demand increasingly increase and high-quality coal stock number falls sharply,
The conversion comprehensive utilization of low-order coal becomes people's increasingly focus of attention.
The process for upgrading of low-order coal is one of the means of low-order coal trans-utilization, is in isolation air or non-oxide gas
Low-order coal is heated to low temperature upgrading in 200-800 DEG C of progress under the conditions of atmosphere, finally obtains the processing side of tar, coal gas and semicoke
Method.But current low-order coal upgrading technology is in experimental study and engineering original application stage, and there is no keep it extensive
The equipment of industrial applications thus limits the utilization of low-order coal.
Tamping coke furnace be coal coking process in the enlarged equipment that uses, floor space is wide, and investment capital cost is big,
The coking process that coking is carried out using tamping coke furnace is primarily referred to as high-temperature coking to obtain coke and recycling chemical products, coke
Product is mainly that metallurgical coke or chemical industry are burnt, due to the coal original for industrially using to the quality requirements of metallurgical coke or chemical industry coke, it
Material includes mainly the coals such as coking coal, 1/3 coking coal, bottle coal, rich coal, lean coal, meager lean coal, belongs to mesometamorphism bituminous coal, due in recent years
The shortage of coal resources, especially be used for coking industry middle high-quality coal raw material reduction so that the raw material of coking industry at
This is growing day by day, in addition the decline of a large amount of industries for needing metallurgical coke or chemical industry coke such as steel, metallurgy in recent years so that coke need
The amount of asking reduction, price fall, to force coke-oven plant to reduce coke output.
Contradictory to be, once coke output reduces, tamping coke furnace can be deactivated, and tamping coke furnace is once out of service
It can scrap, therefore in order to protect the tamping coke furnace equipment for furnishing a huge amount of money for invest to build, would have to maintain coke oven in minimum level
Operation brings the excess capacity of coking industry to cause coke output that cannot be reduced by market demand, two contradict under
How in the case where meeting coke normal volume, the operation of tamping coke furnace is kept to become key.
Low-order coal is the coal of China's rich reserves and there is no the enlarged equipment for low-order coal application at present, if
The tamping coke furnace that middle high-order coking of coal technique can be used is applied in the process for upgrading of low-order coal, then not only facilitating solution
Certainly the problem of coking industry excess capacity, moreover it is possible to be promoted the application of low-order coal.But low-order coal have volatile matter it is high,
The high feature of easy dusting, ash content, the middle high-order coal feedstock specifications used with existing tamping coke furnace are entirely different, it is not easy first
The characteristics of molding, determines that low-order coal can not be pushed into tamping coke furnace carries out coking, the solid production that secondly low-order coal obtains after upgrading
Product are the low-quality product of dusting, and the product of dusting causes tamping coke furnace to be difficult to coke pushing outward, still limits tamping coke furnace again
Use, most importantly the temperature of low-order coal upgrading need to be maintained between 200-800 DEG C, and tamping coke furnace need exist
800 DEG C used above, theoretically so that the low-order coal product obtained after high-temperature retorting loses use value.
Invention content
For solve the problems, such as in the prior art low-order coal cannot achieve large-scale application and existing coking industry excess capacity,
The low problem of tamping coke furnace availability, to provide a kind of raw material carrying out low-order coal upgrading using existing tamping coke furnace.
For this purpose, the technical solution that the present invention takes is,
In a kind of raw material using the progress low-order coal upgrading of existing tamping coke furnace, including low-order coal and auxiliary agent, the auxiliary agent
To completely cut off the organic binder that air destructive distillation weightlessness is less than 50% at 850 DEG C.
In the above-mentioned raw material for carrying out low-order coal upgrading using existing tamping coke furnace, the organic binder is that softening point is big
In 100 DEG C of asphalitine.
