Abstract
The invention relates to the clean coal field and in particular relates to a process for preparing biomass fatlute briquette. The biomass fatlute briquette is prepared through mixing bituminite with the proportion by weight of 80%, fatlute 15% and biomass 4-5% and then pressing in molding equipment under the pressure of 15-20mpa and under the effects of organic modified starch binder, catalysis combustion-supporting agent and sulfur-fixing agent. The briquette of the process can increase the combustion intensity of coal, the burning performances of the briquette is better than that of high grade diffused coal, the briquette can satisfy the requirements of large-scale moving boilers and fixing boilers for the combustion performances and can reach the aim of protecting environment.
Description
Technical field:
The present invention relates to a kind of clean coal field, especially a kind of manufacture method of biomass sludging briquette.
Background technology:
Moulded coal is a kind of mode that the coal clean burning utilizes, and is again the important component part of clean coal, and moulded coal can reduce the problem of environmental pollution in the coal combustion process that looses effectively, helps environment protection.Shaped coal technology has last 100 years history, and each main producing coal country of the world all attaches great importance to the exploitation of shaped coal technology.Asian Economy social commission held regional coal utilization specialists meeting in Philippines in 1989, and theme is " exploitation of moulded coal and an environmental benefit ", and the meeting aim is that socio-economic development will be a prerequisite with keeping the eubiosis with the protection environment.
China is from 20th century the fifties coal briquette for civillan use that begins one's study, and its target is energy-conservation and reduces and pollute.Coal briquette for civillan use commercialization at present.The sixties exploitation industrial shaping coal that begins one's study.During " eight or five ", national moulded coal scientific research institution and universities and colleges obtain remarkable progress aspect shaped coal technology, and obtain many scientific payoffss and patent.Domestic various places have all been built up moulded coal factory in succession over past ten years, and its designed capacity is 3～100,000 tons/year, but actual capacity does not reach designed capacity far away, and some factories do not enter industrialness production as yet at present.Not not normally, systematically according to the briquette production processing requirement equipment that forms a complete production network, but the equipment that is borrowed in industries such as chemical industry, metallurgy, building is used, its equipment can not be adapted to the processing requirement of briquette production well, has influenced the production of moulded coal and the quality of moulded coal; A lot of industrial shaping coals are used for gas making production more, and are applicable to the loose moulded coal of coal burning boiler of the ubiquitous burning of China for production, and the problem of existence is: the moulded coal reactive behavior is lower, and intensity of combustion is not enough, can not satisfy the loose production requirement of coal burning boiler of large-scale combustion; Production cost is higher in addition, and it is higher that additive increases the briquette molding cost, restricts applying of moulded coal.A kind of environment protection clean moulded coal of the present invention's proposition can address the above problem for this reason, and the environment protection clean moulded coal is applied on a large scale.
Summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming, and the manufacture method of a kind of biomass sludging briquette that provides, this method energy adjusting type burning of coal performance, enhancement type burning of coal intensity, the combustionproperty that makes moulded coal near and be better than the high-quality burning of coal performance of loosing, satisfy at large-scale movable bed or fixed bed boiler the fuel combustion performance demands, reach the environmental requirement purpose of clean coal combustion.
Technical scheme:
The task of Ti Chuing for achieving the above object, biomass sludging briquette of the present invention is after being mixed by the biomass of the bituminous coal of weight ratio 80%, 15% greasy filth, 4-5%, under organically-modified starch based binding agent and catalysis burning-rate accelerator and sulphur-fixing agent effect, under 15-20MPa pressure, suppress to form in molding device.
Described bituminous coal be calorific value at 4300-4600kcal/kg, the bituminous coal of volatile matter 20%～25%, granularity is below 5mm; The calorific value of greasy filth 3500～5000kcal/kg, oil-containing 30%～45%, the viscous crude greasy filth of water content≤30%, described biomass are the tangerine bar, described starch based binding agent is a W-Gum, add-on be biomass mix the back total amount 10%～15%.Catalysis burning-rate accelerator: the potassium permanganate add-on is 2 ‰ of a biomass mixing back total amount, and sulphur-fixing agent: the calcium oxide add-on is the 0.8-1% that biomass are mixed the back total amount.
The present invention compared with prior art has distinguishing feature:
Biomass sludging briquette has good combustionproperty, combustionproperty near and be better than the high-quality coal that looses, can satisfy large-scale movable bed or fixed bed boiler to the fuel combustion performance demands, and apply on a large scale; A large amount of greasy dirts that can make in the field produces again to be produced are utilized with innoxious, resource utilization, reach clean coal combustion requirement; Also can replace mineral binder bond fully, reduce the briquette production cost, save the raw coal consumption and realize rationally utilizing the agriculture production waste, biomass energy, the purpose of saving high-quality fossil energy; Can be how body formed during the burning of this moulded coal, split and do not loose, can increase moulded coal combustion reactions surface-area, improve the moulded coal intensity of combustion.
Embodiment:
Embodiment 1: after this invention is mixed by 80% bituminous coal, 15% greasy filth, 4～5% plant straw, under organically-modified starch based binding agent and catalysis burning-rate accelerator and sulphur-fixing agent effect, in molding device, under 15～20mpa pressure, be pressed into the moulded coal of certain specification.
This technical scheme comprises main production and the accessory production system formation.Main production system has: the pre-mixing dispersion system of coal dust, the thick broken system of greasy filth coal dust fine powder, stirring rolling mixing system, formation system, finished product drying system after raw coal coarse reduction system, greasy filth and the pulverizing; Accessory production system has: additive preparation and charging system, biomass pulverizing and add-on system, material-transporting system.
At first, select the bituminous coal of calorific value at 4300～4600kcal/kg, volatile matter 20%～25% during manufacturing, it is sent into raw coal coarse reduction system, it is carried out coarse reduction, smashing fineness is controlled at below the 5mm;
Secondly, select calorific value 3500～5000kcal/kg, oil-containing 30%～45%, the viscous crude greasy filth of water content≤30%, through quantitatively with coarse reduction after coal dust carry out pre-dispersed the mixing by the two-wheel stirrer again, make relatively large viscosity greasy filth under mechanical stirring, adhesion, separation, visbreaking effect by coal dust make greasy filth be dispersed into smaller particles, are convenient to follow-up crushing operation;
The 3rd, it is broken that the thick greasy filth coal dust behind the above-mentioned dispersion mixing is carried out fine powder by shear pulverizer, makes greasy filth and coal dust together pulverize and mix, below the smashing fineness control 3mm;
Four, biomass straw is ground into the material of fineness requirement less than 1.5mm by stalk crasher, the biomass straw after the above-mentioned greasy filth coal dust material that meets production requirement is pulverized by biaxial rneader and quantitative adding;
