Abstract
The environment protection type coal is prepared from anthracite, bituminous coal, coal mud or tailings, lime, etc. through proportioning, grinding, stirring, activating, shaping and processing. The method is characterized in that the energy potential is fully utilized, the emission of pollutants is reduced to the maximum extent, and the capital investment of equipment for purifying the burning raw coal in the furnace can be greatly reduced. The original boiler and stove do not need to be modified with equipment for desulfurization, smoke dust removal and the like, the environment-friendly effect can be achieved by burning the environment-friendly briquette, and the environment-friendly benefit is very obvious. Mechanized production, simple process, energy conservation, consumption reduction, low cost, high return and considerable economic benefit.
Description
The present invention relates to a kind of environment-friendly coal, specifically be to make raw material by hard coal, bituminous coal or coal slime, mine tailing, lime etc., be aided with novel production process, be processed into coal product, environment-friendly coal promptly of the present invention with certain intensity and shape.
Coal is being brought into play enormous function as the energy in national economy, but enters the SO in the atmosphere behind the raw coal combustion
2, CO
2, NO
x, benzo (A) pyrene and trace metal, hydrocarbon polymer, suspended particles, comprise grey particle, unburnt carbon granule etc., jeopardize ecotope and human survival.
China is the country of a typical coal-smoke pollution, and past industry is made fuel with raw coal always, and its thermo-efficiency only utilizes about 60%, there is nearly half heat energy to be taken away by tall and big chimney, a large amount of noxious gas emissions in atmosphere, over-emitting black exhaust, the dust that falls, serious environment pollution.
Moulded coal is made fuel, thermal efficiency ratio is burnt high nearly one times of raw coal, generally can economize on coal more than 15%, and objectionable impuritiess such as SO2, CO2 significantly reduce, and chimney only emits white cigarette, and environmental benefit is very remarkable.Also can significantly reduce the equipment funds input that purifies in stove of burning raw coal simultaneously, original boiler and stove and accessory need not reequip desulfurization, take off equipment such as flue dust, and briquet can reach environment protecting.
Purpose of the present invention just is: energy potential is fully used, and reduces the discharging of pollutent to greatest extent.
The object of the present invention is achieved like this, it is mainly by raw materials such as hard coal, bituminous coal or coal slime, mine tailing, lime, form through processing and preparing such as screening, proportioning, abrasive dust, mixing stirring, activation, moulding, it is characterized in that it is to be made by following weight (%) proportion raw material.
Major ingredient: hard coal 60
Bituminous coal or coal slime, mine tailing 30
Auxiliary material:
Lime: 10
Each raw material of above-mentioned weight proportion is made environment-friendly coal of the present invention, it is characterized in that:
1, presses the standard screening coal, promptly select low-sulfur for use or do not have coals such as sulphur, low ash content, high heating value.
2, with the hard coal of selecting for use, bituminous coal or coal slime, behind the abrasive dusts such as lime, its fineness is not more than 1MM.
3, the finely disintegrated coal dust is fully mixed.
4, when abrasive dust, stir on the limit, and carry with conveyor on the limit, the watering uniformly on coal dust while landing, and water content is no more than 10%.
5, the lime in the proportioning can play and fall sulphur, molding bonded dual function.
6, the coal dust that will spill water is placed activation in 2 hours, respectively contains a certain amount of coal tar in bituminous coal or the coal slime, and its coal tar can activate hard coal naturally, to strengthen the hard coal activity, improves briquet quality.
7, the coal dust after will activating is put into the moulded coal that is pressed into different shape in the molding coal machine, as spherical shape or oblate spherical etc., promptly is prepared into environment-friendly coal of the present invention.
8, the moulded coal after the moulding is through airing slightly, and water content is no more than 7%, with light pressure not during modification, can quantitatively pack into mould compile in the bag pile up, store, loading and unloading, convenient transportation do not pollute again.
Environment-friendly coal of the present invention, raw material sources are extensively, energy-conservation of consumption reduction, reduction pollution, environmental benefit be very remarkable, and mechanize production, technology is simple, output is big, cost is low, high repayment, and economic benefit is considerable.Its quick combustion, firepower is strong, temperature is high, anti-combustion, be fuming few, convenient, healthy, economic, practical.Be applicable to various boilers and stove and accessory.Environment-friendly coal claims green energy resource again.
Claims (4)
1, environment-friendly coal is with hard coal, and bituminous coal, coal slime, mine tailing, lime are made raw material, presses the standard screening coal, is prepared from through scientific matching, abrasive dust, activation, moulding, it is characterized in that it is to be made by following weight (%) proportion raw material.
Batching:
Hard coal Bituminous coal or coal slime, mine tailing Lime
???60 ????????30 ???10
2, according to the environment-friendly coal of claim 1, its feature also is: the described standard screening coal of pressing is with low-sulfur or do not have standard application coals such as sulphur, low ash content, high heating value.
3, environment-friendly coal preparation technology of the present invention is characterized in that:
(1),, require fineness to be not more than 1MM with its abrasive dust all by the proportion scale of claim 1.
(2) to stir behind the abrasive dust.
(3), land while carrying and uniformly water is sprayed on the coal dust with rotary conveyor with the coal dust behind the abrasive dust.Water content＜10%
(4) coal dust that will spray water is placed activation in 2 hours, and activation is exactly respectively to contain a certain amount of coal tar in bituminous coal or coal slime, the mine tailing, mixes with hard coal, leaves standstill in the process, and coal tar can activate hard coal naturally, to strengthen anthracitic activity, the raising briquet quality.
(5) coal dust after will activating is put into moulding in the molding coal machine, promptly makes environment-friendly coal of the present invention.
(6) moulded coal of the present invention can be made into shapes such as the spheroidal with certain intensity, oblate sphere.
(7) moulded coal after making is treated airing slightly, and water content is no more than 7%, when gently pressing not modification, can quantitatively pack into to mould and compile in the bag, is convenient to pile up storage, the loading and unloading transportation.
4, the moulded coal primary standard that is prepared into is:
