Description
Technical field:
The present invention relates to power-saving technology, a kind of environment-friendly and energy-saving smokeless moulded coal be provided especially,
Background technology:
Civilian coal mainly is meant the fuel that is directly used in people's lives as primary energy source, and town dweller of China nearly 80% and 20% peasant rely on the fuel of coal as cooking and heating at present.The consumption of the civilian coal in the whole nation is about 2 hundreds of millions tons.Remove now the needs that civilian coal can be satisfied in minority producing coal area, all the other cities and towns all nervous with coal.
To the greatest extent villous themeda is progressively developed at big city fuel gas, but it can only instead of part fuel, and it is in short supply to play a part to alleviate civilian coal, and coal will be the main body of China small and medium-sized cities and small towns people's lives fuel all the time.According to the pertinent data statistics, the growth of existing annual civilian coal is more than 10%.In order to alleviate the coal supply situation, must do a good job of it the energy conservation of civilian coal by persistence.Past is few to civilian coal processing, and directly burns the coal that looses, and pollutes very general to hygienic condition.
China begins to develop the processing industry of civilian coal from the fifties, promote honeycomb briquette and moulded coal, but slower development is just formally listed state plan in recent years in.At present, national moulded coal annual production be 2,000 ten thousand tons, only account for about 15% of coal consumption of living, under normal circumstances, resident family burns moulded coal and economizes on coal more than 20% than burning the coal that looses.
In addition, multiple industrial dwarf boiler and heating stove are arranged still, using thin loosing during coal, some duff small-particle is missed below fire grate, and the unburned carbon loss that causes nearly more than 20%, can obtain good combustion efficacy if use the ball-type coal instead.
Summary of the invention:
The objective of the invention is to the combustionproperty requirement at the needs and the industrial dwarf boiler of civilian coal, the combustion conditions in particular for adapting to reciprocal grate and chain furnace provides a kind of environment-friendly and energy-saving smokeless moulded coal, and its combustion efficacy is good, thereby saves coal-fired.
Particularly, the invention provides a kind of environment-friendly and energy-saving smokeless moulded coal, it is characterized in that: described coal briquette is by the pitch or the coal tar of 10～15% weight, the wood chip of 10～20% weight or rice husk skin, the clay of 5～10% weight, carbide slag or phosphogypsum, the water glass of 8～10% weight, the smokeless fine breeze of surplus is prepared from.
It is spherical that the shape of environment-friendly and energy-saving smokeless moulded coal of the present invention is preferably circumference.
The present invention also provides the preparation method of above-mentioned environment-friendly and energy-saving smokeless moulded coal, it is characterized in that:
Various solid materials are pulverized, 0.5～4 millimeter of fine particle, wherein 5～6 millimeters of maximum particle sizes is no more than 20%;
Water glass is carried out mixed dissolution with water by 1 to 2～3 prepare liquid-containing binder;
The desired raw material blending stirred to reach hold moulding;
To get the raw materials ready and send into forming press, and go into mold pressing and make type, its compression ratio is 2 to 1;
Depanning is left standstill, and is finished product after the drying.
Among the preparation method of environment-friendly and energy-saving smokeless moulded coal of the present invention, preferably mixture temperature is remained on 60～70 ℃.
Among the preparation method of environment-friendly and energy-saving smokeless moulded coal of the present invention, thermal source used during batch mixing can be elected 120 ℃ steam as.
The present invention is to be aggregate with anthracitic coal washing powder, the multiple fine coal slurry of blending and oxidizer and caking agent, pitch, coal tar are arranged, sawdust powder, wheat health rice husk, cereal peanut skin, apricot Cortex walnut, bark leaf, clay, carbide slag, phosphogypsum, water glass, water etc. are by a certain percentage through pulverizing mixing and stirring, reenter mould shaper compression moulding, depanning is quiet puts, and after drying, is environment-friendly energy-saving anchracite ball fuel.
The main technical details of coal briquette of the present invention is: gross calorific value is 5200 kilocalories, net calorific value more than 4500 kilocalories, carbon content 55～56%, volatile matter 17～18%, ash content 22～23%, moisture 4～5%, ultimate compression strength is 9～10Kg/cm
2, the easy firing noncoking, ash content carbon is below 2%, and the complete flue gas that burns is few.
Environment-friendly and energy-saving smokeless coal briquette of the present invention is mainly supplied resident living cooking, the heating coal, and bathing pool, office, the upright stove of school and industrial dwarf boiler, particularly the combustioncharacteristics to chain furnace and reciprocating grate furnace is then more favourable.The present invention can also be as the feed coal of producer gas generator in addition.The present invention has reduced the pollution to air, helps improving the hygienic condition protection.
The main raw material of environment-friendly and energy-saving smokeless coal briquette particularly of the present invention, it all is the waste material that utilizes, for example: the coal washing powder of raw coal, anthracitic duff face, coal tar, saw foam wood powder, wheat health rice husk, carbide slag, phosphogypsum etc., through recovery processing, it is turned waste into wealth, duplicating becomes regeneration New-type fuel energy-saving coalball, and become the high-grade fuel energy, and then create a new fuel approach.This point has important economic implications under the situation of supply of fuel anxiety.Be a good method of benefiting the nation and the people and achieving many things at one stroke, and be again the good social connections that township and village enterprises gets rich.Its material source is inexhaustible, can gather materials on the spot, and also convenient.Small investment of production equipment, technological operation is simple, and is with short production cycle, instant effect, the economic benefit height, with the source mill that 2～3 workmans produce, its annual value of production can reach more than millions of units.For example calculate by output with a briquetting press, per hour be 3.6 tons, hourly output was 28.8 tons in one day 8, get its integer by 25 tons of considerations, 750 tons of monthly outputs, the output in 1 year are 9000 tons, selling price according to present high-quality coal briquette per ton is 400 yuan of calculating, the output value of every day is 10,000 yuan, and every month the output value is 300,000 yuan, and its annual value of production is 3,600,000 yuan.It only is over one hundred unit that the material cost of coal briquette per ton is taken.Obtain gross profit like this and be doubled and redoubled, this is a cause of fully developing talents.
In a word, under the situation that fuel energy is in short supply at present, utilize remaining waste material, development have environmental-protection function and an energy-conservation novel anthracite ball, can reach the calorific value of fat coal, for domestic life and industrial various dwarf boiler, the fuel coal of chain furnace etc., it has good burning performance, the thermo-efficiency height, and economic worth is good.The technical formula advanced person of this coal briquette, combined composition is rational in infrastructure, draws materials conveniently, and sanitary condition is good, and production technique is easy, good product quality, effects of energy conservation and environmental protection is good, cuts to have wide practical value.
