Abstract
The present invention relates to the granular fuel of crop straws and a preparation method thereof, which belongs to a biomass energy application field. After the crop straws and plant waste materials are naturally dried to a water ratio which is less than 16%, the crop straws and the plant waste materials are pulverized into powdery materials with a particle less than 8mm by a chopping and kneading multifunctional pulverizer, and then, one kind of materials or several kinds of powdery materials are mixed with water. After steam gasification, a mixture is compressed, shaped, cooled, packed, and prepared into the granular fuel in a granulation flat die machine specially used for straw granules. The product particle is from 6 to 9mm, length is from 20 to 30mm, and the water ratio is smaller than or equal to 14 wt%. Under a condition that any additional additive is not added to the granular fuel of crop straws, the prepared granular fuel has the advantages of large density, high shape ratio and high heat value. The present invention has the advantages of simple processing technology, low cost and energy-saving, the granular fuel of the straws can be produced by a small amount of steam, and the present invention conforms to an energy source use and development trend which protects an environment, saves energy, and can also be regenerated and circularly used.
Description
Technical field
The present invention relates to the biomass energy Application Areas, particularly a kind of granular fuel with crop straw that agricultural crop straw makes and preparation method thereof that utilizes.
Background technology
Biomass energy is the important energy source that the mankind depend on for existence always.Biomass energy is as be coal, oil, the Sweet natural gas the fourth-largest energy in addition, be a kind of be the environmental protection clean energy of renewable recycle again, it will become the future world most important one big energy.Development and use biomass energy renewable energy source, the recycling economy of adaptation Sustainable development is promoted national economic development and environment protection all is significant.The birth of biomass energy (particle) gasification fired boiler makes output, the price of biomass energy particle fuel obtain abundant assurance, and this industry is rapidly developed.China every year, only the turnout of stalk just reached 700,000,000 tons, amounted to about 3.5 hundred million tons of standard coal.Whenever use 1 ton of biomass " particle " but reducing emission of carbon dioxide 1500Kg, reduce discharging sulfurous gas 25Kg.Patent disclosure with agricultural crop straw, etc. by pulverize, granular fuel and preparation technology thereof are made in compression, but outer doping such as employing, guarantee the ratio of briquetting and the intensity of granular fuel, increased production cost, and reduced the calorific value of granular fuel indirectly, increased the quantity discharged of refuse.
Summary of the invention
The present invention reduces production costs, improves the calorific value of granular fuel by a kind of granular fuel with crop straw that any outer doping makes and preparation method thereof that do not need to add is provided to reach, reduce the purpose of the discharging of refuse.
The technical solution adopted for the present invention to solve the technical problems is: a kind of granular fuel with crop straw is provided; be with agricultural crop straw and plant refuse seasoning to water ratio after below 16%; be ground into powder below the particle diameter 8mm with pulverizer; then a kind of material or several powder are mixed with water; after steam is softening; compressed moulding in flat die machine, cooling, packing are made granular fuel, and product has following feature:
Particle diameter: 6～9mm
Length: 20～30mm
Water ratio :≤14%.
The preparation method of this granular fuel with crop straw is: with agricultural crop straw and plant refuse as raw material,, granulation softening, cooling, packing and make granular fuel through seasoning, pulverizing, batch mixing, steam; Concrete production craft step is as follows:
A. with agricultural crop straw and plant refuse seasoning, to water ratio below 16% (weight);
B. dried raw material is crushed to powder below the 8mm, mesh size Φ 6～8mm with pulverizer;
C. after powder being added water, mix with mixer, the control water ratio is 18%～22% (weight);
D. the material that mixes is softening through steam, be sent to extruder grain in the tablets press, being pressed into diameter is that 6～9mm, length are the particle of 20～30mm, water ratio is 17%～18% (weight);
E. stalk particle is transported to water cooler internal cooling, screening, makes particle temperature≤40 ℃, the grain forming rate is 96%, and the particle water ratio is≤14%;
F. be packaged into the finished product of 25kg/ bag ± 0.2kg with the multiple film woven bag of handtailor polypropylene.
Wherein, described agricultural crop straw and plant refuse be maize straw, rice straw, wheat stalk, cotton stalk, peanut seedling, melon seedling, soybean stalk, various weeds, rice husk or/and a kind of or more than one mixture in the leaf; When a kind of powder or several powder mixed with water, when the water ratio of control mixture was 18%～22% (weight), the shaped granule fuel that obtains when moisture content is lower than 18% (weight), stopped up template for best easily, yields poorly; When moisture content is higher than 22% (weight), granulation density pine, ratio of briquetting is low, influences next procedure; Described pulverizer is rubbed the formula multifunctional crusher, 2000～2800 rev/mins of its revolutions, screen cloth Φ 6～8mm for hand hay cutter; Described tablets press is the special-purpose flat film tablets press of stalk particle; the control that can automatically adjust of its rate of feeding; it is 100 rev/mins that template is rotated revolution; the template frictionally that wheel changes drives the four rolling of ten son axles; be evenly distributed in the hole on the template rolling clamp-oning of being forced to property of material with it; again through the powerful extruding of high temperature; by the high temperature gelatinization; the protein coagulating sex change; strengthen density gradually, form cylindrical bar, cut off through control grain plate again by after flowing out in the hole under the template; form the right cylinder small-particle, will through batch mixing pan
Make particle by outside the material mouthful outflow machine, template and roller gap are advisable with 0.03～0.2mm.Flat film mode is adopted in the tablets press design, and pressure is even, and discharging is stable, flat membrane pore size Φ 8～9mm, 5～6.5 times of compression ratios. force the pressing materials temperature to be controlled at 80～95 ℃, the unsuitable coking of material, reach the purpose that does not add any additives, to reduce production cost, productivity gain; Described water cooler is a counter-current cooler, and blast is: 220mmkg; Air quantity is: 〉=22m 3./min.Before the molding, granulating, add certain steam, can make material fully softening, output improves 20%～30%.
Stalk granular fuel of the present invention, materials are extensive, are convenient in the rural area promote, and gather materials on the spot conveniently, and technology is simple, does not need to add any outer doping, and apparatus for production line is few, is convenient to maintenance, and every village, every township only need a spot of steam just can produce stalk granular fuel.The granular fuel density of making is big, ratio of briquetting is high, the calorific value height; Complete processing is simple, cost is low,, meet environmental protection, energy utilization energy-conservation, renewable recycle again and development trend.
The present invention will be further described below in conjunction with embodiment.
