A kind of moulded coal of resource reutilization
Technical field
The present invention relates to moulded coal field, particularly a kind of moulded coal of resource reutilization.
Background technology
Moulded coal take fine coal as main raw material, by the machined compression moulding of proportioning, physical strength and shape size required by concrete purposes, has some strength and size and different coal finished product; Moulded coal has that technique is simple, less investment, cost are low, and can obtain and promote coal-fired quality, improve efficiency of combustion, reduce the advantages such as coal burning pollution, is therefore used widely in people's daily life and industrial production as fuel.But coal resources are fewer and feweri, people start more and more to focus on waste resource to be applied in moulded coal, develop economic model capable of circulation.
In China's sugar industry production process, all inevitably produce the waste pollutants such as the very huge filter mud of quantity, waste molasses and sugarcane marrow every year.Wherein except sugarcane marrow is used (on a small quantity as paper making raw material, other are as boiler oil), other wastes are all less than effectively being utilized, only make some halfway environmental protection treatment, direct discharge, sugar enterprise takes huge expenses of environmental protection, does not produce any economic benefit, and can only process about 1/3 of existing waste pollutant.
In rural area, the agriculture and forestry organic waste materials such as stalk, bark, rice husk, only have a small amount of for pasture; or be used as farmland fertilizer; but still have a large amount of more than needed, if can filter mud, molasses and agriculture and forestry organic waste material be applied in moulded coal, will to realizing resource circulation utilization, preserve the ecological environment significant.
Summary of the invention
The invention provides a kind of moulded coal of resource reutilization, adopt filter mud of sugar refinery, biomass fuel as moulded coal raw material, achieve the recycling of waste resource.
For achieving the above object, technical scheme of the present invention is:
A moulded coal for resource reutilization, is made up by weight ratio of following raw material: 40 ~ 50 parts, fine coal, 5 ~ 10 parts, resinous shale, filter mud of sugar refinery 20 ~ 25 parts, 20 ~ 28 parts, biomass fuel powder, 1 ~ 5 part, Wingdale, 0.2 ~ 0.5 part, magnesium oxide, 8 ~ 10 parts, molasses;
Wherein: described biomass fuel powder is soybean stalk, one or more in maize straw, rice husk, mallee bark, eucalyptus branch are dried rear pulverizing and made or make through charing pulverizing.
The moulded coal of above-mentioned resource reutilization, is preferably made up of following raw material: 45 parts, fine coal, 8 parts, resinous shale, filter mud of sugar refinery 23 parts, 22 parts, biomass fuel powder, 3 parts, Wingdale, 0.3 part, magnesium oxide, 9 parts, molasses by weight ratio.
Further, described biomass fuel powder is made: 10 ~ 15 parts, soybean stalk powder, corn stalk powder 10 ~ 15 parts, powdered rice hulls 5 ~ 10 parts and 30 ~ 38 parts, mallee bark powder after shining dry grinding by following raw materials according by weight ratio.
The above biomass fuel powder is made: 12 parts, soybean stalk powder, corn stalk powder 12 parts, powdered rice hulls 8 parts and 36 parts, mallee bark powder after preferably shining dry grinding by following raw materials according by weight ratio.
Further, described biomass fuel powder is after biomass fuel charring, pulverize the powder made, and its manufacture craft is: biomass fuel is put into charring furnace, ignition, after the charing of 4 ~ 5 days, then the fuel after charing is ground into 20 ~ 30 object powder.
The powder made after the above biomass fuel charring, is carbonized by weight ratio by following raw material and makes: soybean stalk 15 ~ 20 parts, maize straw 15 ~ 20 parts, 10 ~ 15 parts, rice husk, mallee bark 36 ~ 50 parts, 5 ~ 10 parts, eucalyptus branch.
Above-mentioned biomass fuel is preferably carbonized by weight ratio by following raw material and makes: soybean stalk 17 parts, maize straw 17 parts, 12 parts, rice husk, mallee bark 45 parts, 8 parts, eucalyptus branch.
The moulded coal of above-described resource reutilization, has following advantage:
(1) described filter mud of sugar refinery is sugar refinery sulfurous method direct production white sugar (single stage method) gained and dry filter mud after deodorizing process, total amount of organic in filter mud can reach 80%, be mainly lipoid (cerosin and sugarcane fat) 5-14%, fiber 15-30%, sugar 5-15%, crude protein 5-15%, total percent of ash 9-20%, this organism is combustible species; In addition, also containing P
2o
5, K
2o, CaO, MgO, can be used as sulphur-fixing agent and combustion synergist uses;
(2) with the addition of resinous shale, resinous shale mainly comprises oil mother, moisture and mineral substance; Wherein, oil is female: content about 10% ~ 50%, is complicated macromolecular organic compound, is rich in aliphatic hydrocarbon structure, and less aromatic hydrocarbons structure; The elementary composition of oil mother is mainly carbon, hydrogen, and a small amount of oxygen, nitrogen, sulphur; Its hydrogen-to-carbon ratio is 1.25 ~ 1.75; For combustible species; Mineral substance: mainly contain quartz, kaolin, clay, mica, carbonatite and sulfurous iron ore etc., containing the alkali and alkaline earth metal ions salt such as potassium, sodium, calcium, magnesium and iron carbonyl aluminum oxide and spinels composition thereof, these compositions improve coal molecular activity, improve the efficiency of combustion of filter mud of sugar refinery and biomass fuel;
(3) apply molasses as binding agent, molasses are byproducts of sugar industry, and viscosity is very high, and bond effect is good, are also the recyclings to waste resource;
(4) add Wingdale as stiffening agent, coordinate molasses to use, accelerate the speed of briquette molding, improve the intensity of moulded coal;
(5) recycle filter mud of sugar refinery, molasses and the agriculture and forestry organic waste material such as stalk and mallee bark, achieving turns waste into wealth, makes the best use of everything, and has positive meaning to environment protection.
