Smoke-abatement sulfur-fixation environment-friendly coal and preparation method thereof

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 [0001] The invention relates to the field of energy, in particular to smoke-eliminating, sulfur-fixing, environment-friendly coal and a preparation method thereof. Background technique [0002] At present, coal, as a fuel, has been widely used in many fields of society. The use of coal has penetrated into every aspect of people's lives. [0003] Generally, coal can be divided into four main types according to its different states of existence, namely raw coal, lump coal, pulverized coal and molded coal. Among them, raw coal refers to the mixed coal mainly composed of lump coal and coal powder obtained directly in the coal mining process; lump coal refers to coal that does not contain coal powder, and the size of the coal block is greater than 6 mm; The coal particle size is less than 3mm; briquette refers to the coal powder is directly mixed with water or the coal powder is mixed with an appropriate amount of lime or clay and then watered evenly, and then p...

Problems solved by technology

[0004] However, the above-mentioned coals all have the problems of large sulfur dioxide emissions and large smoke dust during combustion, which seriously pollutes the environment.
