Description

The integrated process equipment of brown coal drying and upgrading

Technical field

The utility model belongs to the coal process equipment, the integrated process equipment of particularly a kind of brown coal drying and upgrading.

Background technology

China is the country that takes the primary energy resource with coal as the leading factor, has become world's first coal power.In coming few decades, China's sustainable development of economy will continue to rely on coal that main energy support is provided.Interrelated data shows that coal in China output in 2004 has reached 1,600,000,000 tons, and 2006 above 2,100,000,000 tons.The coal resources in China recoverable reserves occupies the third place in the world, accounts for 11.5% of world's gross reserves.Wherein the brown coal reserves account for 16% of world's brown coal gross reserves.The exploitation of the coal resources of China at present and utilizing based on bituminous coal and anthracite, the exploitation of brown coal and utilize level very low.Along with China to the continuous increase of energy demand with to the excessive exploitation of bituminous coal, anthracite resource, will be more and more important to the development and utilization of brown coal.To rise rapidly according to China's brown coal output after the expectation 2008-2010 of the parties concerned, will reach hundred million tons of 2-3 every year.Compare with bituminous coal, anthracite, the advantage of brown coal is that price is lower, the reactivity height, but its calorific value is relatively low, and water content is higher.Therefore one of key of brown coal development and use is the exploitation of brown coal drying and upgrading technology.

Generally adopt the steam drying process that brown coal are carried out drying at present abroad, directly deliver near coal-mine power plant then and be used for combustion power generation.With external different be, the near coal-mine power plant of China quantity is few, and most of power plant is away from the colliery.Therefore need could arrive the coal-burning power plant through long-distance transport after the exploitation of the coal resources of China, the Coal Transport radius is bigger.This development and utilization to lignite resource is had higher requirement.Consider that from cost of transportation and combustion heat value aspect brown coal need just can be transported to power plant's burning after drying.Brown coal after the dry processing of the steam of U.S.'s exploitation are called K-fuel, do not solve the problem of brown coal spontaneous combustion, even the possibility of spontaneous combustion is increased, and are not suitable for the national conditions of China's lignite resource development and use.Mechanical hot extrusion (MTE) technology of brown coal research center, Australia (Lignite CRC) research still is in the laboratory research development phase.This technical finesse efficient is extremely low, the brown coal water content after the processing still higher (containing higher moisture content as Victoria's brown coal after handling).The brown coal drying technology of developing that Japan NEDO subsidizes is to utilize heavy oil and brown coal mixed processing, realizes the drying and the modification of brown coal.This technology is applicable to lique faction of coal technology, and processing cost is higher, consumes a large amount of heavy oil, also is not suitable for China's national situation.In general, still there is not ripe brown coal drying technology and equipment at present.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, and cost is low, can carry out the equipment of the integrated processing of drying and upgrading to brown coal.

The technical solution of the utility model is: a kind of by motor (1), hot air apparatus (4), air-introduced machine (6), eccentric swage motor (8), feeding screw (9), eccentric swage (13), frame (14), the brown coal drying and upgrading integration apparatus that framework platform (24) and finished product coal bunker (28) are formed, be characterized in frame (14), be installed with pressue device (5) on the framework platform (24), pressue device (5) comprising: in the bearing (33) on pressue device housing (5-1) a plurality of rolls (15) are housed versatilely, be fixed with a gear (22) respectively at each roll (15) one end, No. two gears (18), No. three gears (20) and No. four gears (17), one, No. two gear is meshed, three, No. four gear is meshed, roll on the left side (15) gear two ends are fixed with No. two belt pulleys (23) and No. four belt pulleys (34), the gear end of the roll of lower left (15) is fixed with No. three belt pulleys (19), be in transmission connection with ancillary drive belt (21) between No. four belt pulleys (34) and No. three belt pulleys (19), the circumference of each roll (15) is evenly distributed with a plurality of grooves (32), a ramp plate (16) is housed in each groove (32), and an end of ramp plate (16) is fixed in the pressue device housing (5-1); Roll (15) center is provided with high-temperature flue gas chamber (31), and two ends, high-temperature flue gas chamber (31) are fixed with high-temperature flue gas entry joint (29) and high-temperature flue gas outlet connection (30).

The utility model can realize to brown coal drying and process for upgrading having the flexibility and the integration of height in one; Through the brown coal after the processing, ature of coal improves greatly, and self-ignition index reduces greatly, can equally with the high-order coal be fit to long-distance transport and storage, and calorific value improves 300～500Kcal/Kg; It is compared with the MTE technology of abroad developing at present, this process equipment has high production efficiency, drying effect is good, operating cost is low, ton coal integrated cost is 50～80 yuan, and the incorporate integrated cost of ton coal drying and upgrading is 80～100 yuan, is developing the drying and upgrading technology with Japanese NEDO and is comparing, cost also reduces greatly, does not need to consume simultaneously the heavy oil resource.
