Abstract
The invention discloses smoke-abatement sulfur-fixation environment-friendly coal and a preparation method thereof. The smoke-abatement sulfur-fixation environment-friendly coal comprises the following compositions in parts by weight: 60-80 parts of raw coal, 10-30 parts of ore asphalt, 4-15 parts of quicklime, 0.2-0.7 parts of ferrocene, and 0.3-0.8 parts of an industrial salt. The above smoke-abatement sulfur-fixation environment-friendly coal employs a high-molecular organic compound-ore asphalt as a basic raw material, and employs ferrocene, the industrial salt and ore aslphat for giving play to effect of fixing sulfur in the reaction, so that sulfur dioxide in the fire coal is reacted and generates magnesium sulfide and calcium sulfide which are kept in ash residue, and the discharge capacity of sulfur dioxide when raw coal is combusted is reduced. Ferrocene, quicklime and ore asphalt give play to the smoke abatement effect. The added industrial salt enables the smoke-abatement sulfur-fixation environment-friendly coal to have relatively fast combustion speed and full combustion during combustion, enables black smoke generated in the raw coal combustion process to become green smoke or white smoke, reduces the smoke release time to be less than 2 min, and relatively accords with environment protection idea.
Description
Technical field
The present invention relates to energy field, particularly relate to smoke-eliminating sulfur-fixing environment protection coal and preparation method thereof.
Background technology
At present, coal, as a kind of fuel, obtains applying very widely in many fields of society.The use of coal has penetrated into all respects of people's life.
Usually, the state difference that coal exists by it mainly can be divided into four kinds, i.e. raw coal, lump coal, coal dust and moulded coal.Wherein, raw coal refers to and directly obtains in progress of coal mining, primarily of the Mixture Density Networks of lump coal and coal dust composition; Lump coal refers to not containing coal dust, and coal cinder size is all greater than the coal of 6mm; Coal dust refers to that the coal particle size contained all is less than the coal of 3mm; Moulded coal refers to and directly to be added water by coal dust and even or add water after coal dust is mixed appropriate lime or clay evenly, then is pressed into the coal with certain specified shape with model.
But all there is the problem that quantity discharged is large and flue dust is larger of sulfurous gas in above-mentioned coal, environmental pollution is serious when burning.
Summary of the invention
Based on this, be necessary smoke-eliminating sulfur-fixing environment protection coal providing a kind of smoke-eliminating sulfur-fixing effective and preparation method thereof.
A kind of smoke-eliminating sulfur-fixing environment protection coal, by weight, comprises following component:
Raw coal 60-80 part, ore deposit pitch 10-30 part, unslaked lime 4-15 part, ferrocene 0.2-0.7 part, Industrial Salt 0.3-0.8 part.
Adopt ferrocene, unslaked lime and ore deposit pitch, good smoke effect can be played.The weight part controlling ferrocene is 2-3 part, both can realize good smoke effect, and can reduce production cost again.
Wherein in an embodiment, by weight, raw coal 68-72 part, ore deposit pitch 16-26 part, unslaked lime 4-10 part, ferrocene 0.4-0.6 part, Industrial Salt 0.4-0.6 part.
Wherein in an embodiment,
By weight, following component is comprised:
