Abstract
The present invention relates to a method for producing high-quality coke, which provides the technical scheme for coal blending by using a common mechanical coke oven device and technological conditions thereof. In the present invention, 1/3 coking coal made in China, fat coal, No. 1 coking coal and No. 2 coking coal are used as raw materials. Thus, the quality of production coke is increased by 2 to 3 levels, and reaches the quality of special-level coke. The present invention has the advantages of low investment cost, obvious technical benefit and economic benefit and easy popularization and production. Thereby, the urgent requirements of high-quality coke which is increased day by day in native and foreign markets are satisfied.
Description
The present invention relates to the method for coking, be specially under common mechanical coke equipment and coke making process condition thereof, a kind of technical scheme of producing the feed coal proportioning of high grade coke is provided.
Along with progress of science and technology and development, increasing to high grade coke (as metallurgical coke) requirement; And China is big coal country, and coal resource is very abundant, owing to the various brands to coal, character, composition lacks multianalysis and deep understanding, lacks rational coal blending scheme in coke production, therefore, for a long time, with the coke that common cokery and technical process thereof are produced, mostly be two, three grades of products, do not reach the quality index of high grade coke, thereby do not satisfy on the market the demand of high grade coke, make the abundant in coal resource fail to obtain to make full use of.
For making full use of the coal resources of China's abundant, it is raw material with homemade coal resources that the object of the invention provides a kind of, utilizes the coal blending scheme of the production high grade coke of existing cokery and technical process.
The present invention is in the various brands to homemade coal, character, composition are understood in depth, and through field trip, on the basis that many ore deposit point sample examinations are analyzed, repeatedly coal blending experiment and analysis and research are carried out in cokery equipment and technical process in conjunction with existing coke-oven plant, are raw material (table 1) with homemade coal, through reasonable proportioning, have under the cokery equipment and technical process condition thereof of producing two, three grades of coke abilities existing, can produce high grade coke fully.The weight proportion of the coal blending technical scheme feed coal of production high grade coke of the present invention is:
1/3 coking coal 20-30%
Rich coal 5-15%
No. 1 30-50% of coking coal
No. 2 10-25% of coking coal
Above-mentioned mixing coal blending is after the coal washing operation enters the specification of quality of the cooperation cleaned coal before the charring furnace should be:

To cooperate the cleaned coal cokery coking chamber of packing into, can produce routinely under the mechanical coke equipment and processing condition thereof of two, three grades of coke abilities, can produce high grade coke.
The coal blending raw material that coal blending technical scheme of the present invention is selected all is state's producing coals, as Taiyuan, Shanxi, Linfen, Luliang Prefecture, Zaozhuang, Shandong, the coal on ground such as tafelberg, Henan; Be applicable to the various type of furnaces of present coal chemical enterprise, as 58-1 type, 58-2 type, JN60-82 5#-6#, 1#-2#, JN43-80III, red flag-1#, red flag-2#, 85-I type, 85-VI type etc.; Need not change and produce coke technical process (as making compacting firm by ramming), need not stop production, not add any additives (as refinery coke etc.); Do not influence the quantity of the coking chemistry product (as coal gas, coal tar, crude benzol, ammonia etc.) of coke-oven plant, just can make general coke-oven plant on the quality base of original production coke, improve the 2-3 level, thereby reach the unusual effect (table 2) that utilizes homemade raw coal to produce high grade coke; Owing to do not need facility investment, raw coal aboundresources, need not change technical process, cost of investment is low, and is easy to promote and produces, and is higher than ordinary coke to satisfy the in short supply and price in present domestic and international market, produces high grade coke, and its economic benefit is very considerable.
