Abstract
Relating to environmental protection and energy saving technologies and recycling of low-carbon content materials like coal gangue, coal cinder, peat, inferior coal, lignite, weathered coal and carbonaceous shale, the invention provides a low-carbon material high-efficiency renewable fuel. According to the invention, the low-carbon material is blended with 5-10wt% of assistants including a combustion supporting agent, a bonding loosening agent, an oxidizing agent, a catalyst, a renewable energy agent and water to conduct processing into moulded coal. The product provided by the invention and domestic moulded coal processed from common fuel coal have an equivalent combustion value, and the combustion effects like ignition difficulty, the fire available time, and the highest flame height are all better than those of ordinary domestic moulded coal.
Description
Technical field
The present invention relates to material that carbon content is low as coal gangue, cinder, mud coal, low grade coal, brown coal, weathered coal, culmiferous recycling, relevant with environmental protection, power-saving technology, specifically, be a kind of low carbon species highly efficient regeneration fuel.
background technology:the material of some low carbon contents is as coal gangue, carbon content is about 12～25%, its combustion value is measured and is generally 800～2000 cards/g by carbon, if the low material of these carbon content is made moulded coal as coal gangue, conventionally all to add 20～30% tackiness agent as yellow mud, coal etc., thereby the carbon content that makes the material that original carbon content is low becomes lower, except affecting the combustion value of moulded coal, also there is difficult point combustion, the shortcomings such as smog is large, thereby with produced in conventional processes coal gangue moulded coal, as domestic life coal, common people are referred to as low-quality goods, in order to improve the carbon content of coal gangue or other low carbon content materials, improve calorific value, common way is coal or the charcoal that adds volume in coal gangue, again by traditional method processing moulded coal, common add-on at least wants 20～30%, as " compound method of coal gangue fuel ", application number 88106225, in coal gangue with regard to coal blending 20～30%.
Inventor finds in long-term briquette production, in general coal, carbon content is 60～75%, combustion value 4000～6000 cards/g, conventionally briquette production all will add 40～50% yellow mud to make tackiness agent, wherein carbon content is actual is 40～50% for the moulded coal processing like this, has approached the carbon content in coal gangue, that is to say, if do not add tackiness agent in the moulded coal that coal gangue is made, the moulded coal combustion value that its combustion value of the moulded coal processing should process with common fire coal is suitable.Inventor also finds, some low carbon speciess are owing to containing a large amount of shale and shale, if be crushed to 80～100 orders, itself just has good viscosity, need not add any yellow mud and make tackiness agent and just can be processed into moulded coal.Inventor also finds, if add some regeneration combustion source agent in low carbon species, the moulded coal being processed into coal gangue, it is also high that its combustion value produces the combustion value of calculating than its carbon content, this may be that the molecule of the non-carbon component in regeneration combustion source agent and the coal gangue adding or atomic structure are broken up and reconfigured the cause releasing energy, also may be that non-carbon species in the regeneration agent of combustion source and coal gangue is produced more stable material and produced Entropy Changes and discharge more energy in combustion processes, for making moulded coal be easy to ignite, suitably add a small amount of charcoal.
summary of the invention: object of the present invention, utilize exactly contriver's discovery, the coal bar of the combustion value that low carbon species or coal gangue are processed into and coal-fired processing, coal briquette moulded coal combustion value is suitable, even than the better coal bar of the briquet quality of fire coal processing, coal briquette, coal consumption of living is made in supply market, reaches the pollution of waste product resource recovery and rationally use, minimizing environment.
A kind of low carbon species highly efficient regeneration fuel, it is characterized in that by 1 ton of coal gangue and other ignition dope charcoals 40～50kg, bonding raising agent methylcellulose gum 2～3kg, oxygenant saltpetre 15kg, catalyzer phenylformic acid 2kg, as FeS 30～40kg, preparation adds water renewable energy resources agent metallic sulfide, the moulded coal processing.
The low carbon species of above-mentioned indication comprises cinder, mud coal, low grade coal, brown coal, weathered coal, yeath.
The metallic sulfide of above-mentioned indication also comprises CaS, pyrite or metallic sulfide slag.
Coal gangue granularity of the present invention is at 80～100 orders, and the weight proportion of coal gangue and other auxiliary agents is 100: 5～10, and requires to mix, and amount of water is advisable with molding coal machine shaped coal.
Feature of the present invention:
1, the present invention adds regeneration thermal source agent, may with coal gangue in metal oxide at high temperature reconfigure, discharge more multipotency, thereby its combustion value produces higher than combustion value that wherein carbon content is calculated.
2, the amount of auxiliary that the present invention adds in coal gangue is 5～10%, and is all the material that can improve the low carbon species moulded coal of coal combustion value, thereby moulded coal combustion value is further improved.
3, the present invention does not add yellow mud and makes tackiness agent, and moulded coal carbon content is not diluted.
4, additive of the present invention makes moulded coal ventilative in combustion processes, and carbon burning is more complete, remaining without some black carbon from outside to inside for whole moulded coal charcoal.
embodiment:
Embodiment 1
Get 1 ton of carbon content 20% coal gangue, be crushed to 80～100 orders, admix wood charcoal powder 50kg, methylcellulose gum 3kg, saltpetre 15kg, phenylformic acid 2kg, FeS powder 30kg mixes thoroughly, add water to expert and pinch agglomerating being advisable, be processed into honeycomb briquette, water content 7% simultaneous test: get the coal 1000kg of carbon containing 70%, yellow mud 200～300kg, it is in the same size with coal gangue honeycomb briquette that machine is made honeycomb briquette water content 10%, specification is consistent, both burnt in domestic honeycomb briquet, and chimney-free air blast.
Burning result comparison: respectively get 3 honeycomb briquettes, 2kg is heavy.With the test of GB6412-86 domestic stove, contrast evaporation test, evaporating pan diameter 16cm, water 5000ml.
