Carbon-rich coal

Abstract

The invention relates to carbon-rich coal which comprises the components of a natural raw coal synthetic base material, a modified plant optimization material, an environmental-friendly purificant, an energy polymerization accelerant and the like. The carbon-rich coal is formed through chemical and physical transformation processes and scientific matter rearrangement. The finished product of the carbon-rich coal not only has significant change and optimized rearrangement in structure, properties, performance and quality, but also achieves the purposes of increment of combustion value and thermal efficiency, energy saving and environmental protection. The reproducibility of the carbon-rich coal is strong, the original coal energy source can be saved to a large extent, and the saving rate is as high as 50-80%; the carbon-rich coal has the calorie as high as 6000-7200, contains only 0.2-0.5% of sulfur and 50-65% of fixed carbon, has the Ringelmann number of 20-40%, is excellent and clean, and has high quality, thereby being called as carbon-rich coal. The carbon-rich coal can be widely applied to industry and civil use and has wide application, great significance and extreme perfectness.

technical field [0001] The invention relates to a high-performance carbon-rich coal with multiple energy conversion and material recombination, more specifically, a high-quality, non-coking, non-polluting, high-performance coal that is suitable for various industries and civil uses High-quality, energy-saving and environmentally friendly carbon-rich coal fuel, its carbon-rich coal calorie is as high as 6000-7200 kcal, the sulfur content is only 0.2-0.4%, the Ringelmann smoke is 20-30%, and the fixed carbon content is as high as 55 -65%, very good, high-quality coal, so it is called "rich coal". The invention also relates to a production method of rich carbon coal. Background technique [0002] At present, various coals are known, such as: natural coal long-flame coal, lean coal, non-caking coal, gas coal, coking coal, fat coal, candle coal, algae coal, weakly caking coal, fine coal, anthracite, lignite , as well as artificial coal coke, briquettes, coal natural aids, etc. ...

AI Technical Summary

Problems solved by technology

[0006] 1. Existing various bituminous coals: natural coal types such as long-flame coal, lean coal, gas coal, coking coal, fat coal, etc. do not have high-efficiency performance and environmental protection performance, and must be processed through performance improvement, reorganization of coal structure and artificial processing Therefore, a single coal component (that is, a kind of coal) can never achieve high efficiency

[0007] 2. Anthracite: Although its own efficiency is high, coal resources are relatively limited. In addition, the efficiency of human use is not high, and coal structure restructuring has not been carried out, and efficiency has not been improved. Therefore, coal-free has become a situation where gold is used as pig iron.

[0008] 3. Candle coal, algae coal, weak caking coal, etc. of natural coal types: Another kind of coal, which does not have high efficiency and environmental protection performance, and also needs energy synthesis and artificial improvement. If the coal structure and composition are not restructured , can never reach its high efficiency

[0010] 5. Clean coal: it is the product of the coal washing plant, which wastes a lot of coal slime, coal gangue and medium coal resources, which is not desirable at all, and its economic value is not high; it also pollutes the environment

[0011] The efficiency of the above raw coal is very low. When used directly, it will cause serious pollution to the atmosphere and the natural environment, and the storage and transportation costs of the raw coal are very high. If the raw coal is not processed, the structure of the coal is changed, and artificial processing The use of raw coal will be more harmful, which is also a waste of raw energy, and at the same time accelerates the consumption of raw energy. Long-term use and deep mining will cause great harm to human beings.

On the other hand, the degree of harm is deeper: there are also deep damage to mountains, landforms, and landforms, as well as casualties of a large number of mining personnel. Due to rapid mining, it can also cause ground subsidence, crustal changes, and earthquake disasters, and at the same time accelerate the damage to the earth and land. Serious damage to the human living environment

[0012] 6. Coke: Although the utilization rate is better in the industrial and metallurgical fields, and the combustion value has increased; but it has no coal-saving performance. During production, whether it is manual production or mechanical coke production, its cost is high

At present, the vast majority of cokes are produced by machine coke. Although the production of coke by machine is large, not only the cost is high, but the secondary pollution is more serious; and the production investment is relatively large. Due to the pollution during production, most Coke and coking plants have been ordered to close and restrict development by the government

[0013] 7. Existing molded coal: refers to various molded coals, such as briquette, ball coal, etc. Since yellow mud or sodium silicate is used as a binder, when burning, the yellow mud itself consumes part of the heat energy, wasting energy, and its thermal efficiency is low , and because sodium silicate is easy to absorb moisture and decompose, which affects the strength of coal, it is inconvenient to store and transport, so the utilization rate of briquette is low, and its economic added value is also relatively low. Since briquette is generally domestic coal, about It accounts for more than 20% of the total coal sales. For a long time, due to the backward technology of domestic coal use, the thermal efficiency is only about 20%, wasting a lot of energy, and the pollution level cannot be reduced, resulting in serious scattered and universal pollution.

However, the overall efficiency is not high, and because there is no material reorganization and coal structure change, the highest coal saving rate does not exceed 10%; if the quality of raw coal is not fundamentally changed, it is impossible to solve the problem of waste of raw energy and reduce The pollution problem of the original energy source; so the comprehensive coal-saving rate of the coal combustion accelerant and the present invention is more than several times, which is far away; and the coal-saving rate and the unique high-efficiency performance of the rich carbon coal of the present invention can never be reached
