Abstract
The invention relates to Ramsbottom carbon clean-type coal and integration technology thereof. The clean-type coal contains 70 to 85 percent of Ramsbottom carbon powder and 15 to 30 percent of biochemical pulverized coal. The integration technology comprises that: the Ramsbottom carbon powder and the biochemical pulverized coal (pulverized coal treated by a biochemical agent is added) are pulverized into powders with the granularity of less than 3 millimeters respectively; and the mixed powders are added with 8 to 10 percent of a composite caking agent, the mixture is evenly stirred, molded under pressure of 60 kg/cm<2> and dried. The integration technology has the advantages that: 1, the technology greatly promotes the added value of the Ramsbottom carbon powders and the pulverized coal and effectively utilizes low-grade or waste coal carbon powder resource; 2, the clean-type coal has high heating amount which can reach between 6,000 and 7,000 kilocalories/kilogram, and has full combustion, and the thermal efficiency of the clean-type coal is more than 1.2 times of that of crude coal; 3, the manufactured clean-type coal has no smoke, low sulphur and low ash during combustion and is environment-friendly clean-type coal; 4, the manufacturing method solves difficult problems of non-cohesiveness of a main material and waterproof technology after molding; and 5, the coal can replace lump coal and can be widely used in an industrial boiler.
Description
Technical field
The invention belongs to Industrial Coal Briquette Technology, mainly is the clean moulded coal of a kind of high heating value, smokeless, low-sulfur and waterproof.
Background technology
Coal is the main body of China's energy, and its dominant position does not have basic change in quite long from now on period.Industrial Boiler of China and kiln all are to loose to burn basically at present, and thermo-efficiency is low, and environmental pollution is serious.Because contaminate environment during raw coal combustion is restricted in many vital areas uses.The development shaped coal technology is the important channel that changes this situation.After Industrial Boiler, kiln are used moulded coal instead, can reach economize on coal, depositing dust, minimizing discharge of harmful gases.With the diffusing coal facies ratio of burning, can economize on coal 15～20%, improve thermo-efficiency 10～15%, reduce smoke discharge amount 60～80%, reduce strong carcinogens (Bap) quantity discharged more than 50%, reduce sulfurous gas (SO
2) quantity discharged is more than 60%.After using Ramsbottom carbon clean-type coal and integrated technology, not only solved the environmental protection pre-treatment of coal fuel, can also effectively utilize low-grade or depleted coal dust resource, promote the added value of blue charcoal end and coal dust greatly, reduce of the pollution of discarded coal dust simultaneously environment.Emphasize in State Council approved " Chinese clean coal technology the ninth five-year plan and development outline in 2010 ":, must develop the clean coal technology that tallies with the national condition for China's economy and society can realize Sustainable development.
Summary of the invention
The present invention's (Ramsbottom carbon clean-type coal) is primarily aimed at industrial moulded coal, can be widely used in Industrial Boiler and kiln and.The present invention adopts the integrated moulding of biochemical coal dust (adding the coal dust that biochemical agent was handled) of 70%～85% blue carbon powder and 15%～30%.Using Ramsbottom carbon clean-type coal and integrated technology is the effective ways that solve the pre-treatment of coal fuel, this Ramsbottom carbon clean-type coal and existing " blue charcoal the anthracite briquette " (patent No.: 200710090540) compare, (example) has the following advantages: with Shanghai bean product industry chain furnace is example, 1, burning-point is low, and 200 degree can be lighted.In chain furnace used, Ramsbottom carbon clean-type coal can be lighted after entering the combustion chamber, after-flame just in time when moving to combustor exit; And " blue charcoal anthracite briquette " because of the burning-point height, just lights when running to the middle part in chain furnace, just reaches prosperous burning degree when moving to outlet, causes energy dissipation.2, flare height.Flame height can satisfy the requirement of chain-grate boiler during the burning of ciii Ramsbottom carbon clean-type coal, makes boiler produce enough steams; And " blue charcoal anthracite briquette " when burning flame too low, can not satisfy the requirement of chain-grate boiler, can not produce enough steams.3, has water-proof function.Ramsbottom carbon clean-type coal is placed in the water to soak and also can be out of shape in one month, and " blue charcoal anthracite briquette " do not have water-proof function, suffers in transportation that rainwater soaks will soften, and can not stack for a long time in the open.

Embodiment
The blue carbon powder of employing 70%～85% and 15%～30% coal dust.Coal dust adds the biochemical additive of Bio-CoUp coal earlier through biochemical treatment, is crushed to respectively below 3 millimeters with blue charcoal end then, adds 8～10% compound binding agent again, and the back that stirs is at 60kg/cm
2Forming under the pressure after dry.
The effect of the biochemical additive of Bio-CoUp coal: 1, realize environmental protection treatment before the coal combustion, can reduce that (NOx) is about 60%, (SOx) about 40%, (CO) about 40%.2, electron transport in the accelerate combustion process makes combustion heat oxidizing reaction more complete, increases combustion heat benefit 10%.3, reduce residual hydrocarbon emission due to the incomplete combustion, improve the slagging scorification phenomenon 30% of bad coal.
The biochemical additive composition of Bio-CoUp coal: biologic ferment group.
Claims (2)
1, contains 70%～85% blue carbon powder, 30%～15% biochemical coal dust in the clean moulded coal by weight percentage.
2, the integrated technology coal dust adds the biochemical additive of Bio-CoUp coal.
