Abstract
The invention discloses a novel coal slime composite fuel which is characterized by being prepared by mixing the following components in parts by weight: 70-90 parts of coal powder, 70-90 parts of coal slime, 35-45 parts of straws, 1-2 parts of smoke suppressor, 3-4 parts of lime, 0.5-0.7 part of sodium hydroxide, 1.0-1.4 parts of sodium nitrate, 0.3-0.6 part of starch, 4-5 parts of magnesium oxide and 1-4 parts of calcium carbonate. The preparation method comprises the following steps: pulverizing the above materials, stirring, and naturally returning for 5-8 days to obtain fuel for combustion; by adopting the technical scheme, the combustion duration is 1.5-2 hours, no peculiar smell exists, white smoke is generated by combustion, the brick is low in carbon, low in sulfur and low in nitrogen, environment-friendly, the calorific value generated by combustion can reach 4000 kilocalories, industrial and civil purposes can be realized, a boiler and civil heating can be realized, and the waste materials after combustion can be used as raw materials of baking-free bricks; the method has the advantages of low cost, resource saving, less environmental pollution, high efficiency, energy saving and environmental protection, and the gangue and the straw are used as main raw materials, so that the waste resources are recycled.
Description
Technical field
What the present invention relates to is a kind of compound fuel, be specifically related to be a kind of be the compound fuel and preparation method thereof of main raw material with the coal slime.
Background technology
Economic growth be unable to do without industrial expansion, and industrial expansion be unable to do without the exploitation of resource, and coal is as the important energy resource, and demand also is to increase day by day, and the coal mining mechanization degree also is constantly to improve naturally.The exploitation of coal, a large amount of coal washing of washery, when coal washing amount in washery increased, the coal slime that washes out also constantly increased, and in the coal washing process one of the impurity in a part of fine coal and the coal, dust etc. was washed out, and became coal slime through precipitation form.It is big that coal slime contains moisture, and fuel value is low, and difficult comprehensive utilization causes resource to waste.
And at present, coal resource is fewer and feweri, and coal slime is as the sub product that produces in the washing process, because of have fine size, retentiveness is strong, ash content is high, and contains characteristics such as more clay, has brought inconvenience to the comprehensive utilization of coal slime.At present the coal slime overwhelming majority of washing mill all cheapness sell to local peasant, not only polluted environment but also caused the waste of resource, the economic worth of coal slime does not obtain really excavating fully.Therefore, in the face of weary coal resources and the high coal price of bursting day by day, coal slime as new fuel feedback with extremely urgent.
Summary of the invention
To the deficiency that exists on the prior art, the present invention seeks to be to provide a kind of cost low, save resource, low in the pollution of the environment and energy-efficient novel coal slime compound fuel and preparation method thereof, it is to be main raw material with the coal slime, is to recycling of waste resources.
To achieve these goals, the present invention realizes through following technical scheme:
A kind of novel coal slime compound fuel; It is characterized in that it is to be mixed and made into by following compositions in weight portion: coal dust 70～90, coal slime 70～90, stalk 35～45, smoke suppressor 1～2, lime 3～4, sodium hydroxide 0.5～0.8, SODIUMNITRATE 1.0～1.4, starch 0.3～0.6, Natural manganese dioxide 4～5, lime carbonate 1～5.
According to above-mentioned a kind of novel coal slime compound fuel; Wherein, it is to be mixed and made into by following compositions in weight portion: coal dust 80, coal slime 80, stalk 40, smoke suppressor 1.5, lime 3.5, sodium hydroxide 0.6, SODIUMNITRATE 1.2, starch 0.5, Natural manganese dioxide 5, lime carbonate 2.
As another object of the present invention, the preparation method of above-mentioned a kind of novel coal slime compound fuel is: with above-mentioned materials pulverize, mixing and stirring, returned property 5-8 days, returning property naturally, the use of burning can act as a fuel.
The present invention adopts technique scheme, and incendivity continues duration 1.5-2 hour free from extraneous odour, and burning generates white cigarette; Low-carbon and low-sulphur hangs down nitrogen, environmental protection; Burning generate calorific value can reach 4000 kilocalories industry and civilian hold concurrently can, boiler and civilian heating all can, after the burning waste material can be used as non-burning brick raw material; Its cost is low, saves resource, low in the pollution of the environment and energy-efficient, environmental protection, and it is to be main raw material with coal gangue and stalk, is to recycling of waste resources.
