With the development of society, human beings demand more and more energy, but the reserves of fossil resources on the earth are gradually decreasing. Under the current situation that oil resources are facing depletion and the awareness of environmental protection is becoming stronger, the impact on the earth The most abundant and renewable biomass resource in the world is imminent. my country is a big agricultural country. According to relevant statistics in 2012, the total annual output of crop straw in my country is 604 million tons, the amount of wood residues in the national forestry industry is 40 million cubic meters, and the amount of wood residues produced by the paper industry is about 10,000 cubic meters. The annual output of rice and bagasse is about 40 million tons. Most of the residues in these industries are reduced to waste. The traditional treatment method is to burn them in the open air.

生物质固体成型燃料是一种典型的生物质固体成型燃料，具有高效、洁净、点火容易、CO2零排放等优点，可替代煤炭等化石燃料应用于炊事、供暖等民用领域和锅炉燃烧、发电等工业领域。2011年3月16日发布的《中华人民共和国国民经济和社会发展第十二个五年规划纲要》提出，结合城市大气环境治理，大力推动城市燃煤锅炉改造为生物质成型燃料锅炉，减少城市燃煤量，扩大规模化的生物质成型燃料市场；到2015年，生物质成型燃料年利用量达到1000万吨，相应替代化石能源500万吨标准煤。Biomass solid briquette fuel is a typical biomass solid briquette fuel. It has the advantages of high efficiency, cleanliness, easy ignition, and zero CO2 emission. It can replace coal and other fossil fuels and be used in cooking, heating and other civil fields, as well as boiler combustion and power generation. industrial field. The "Outline of the Twelfth Five-Year Plan for National Economic and Social Development of the People's Republic of China" issued on March 16, 2011 proposes to vigorously promote the transformation of urban coal-fired boilers into biomass briquette fuel boilers in combination with urban atmospheric environment governance, reducing urban Coal consumption, expanding the large-scale biomass briquette fuel market; by 2015, the annual utilization of biomass briquette fuel will reach 10 million tons, correspondingly replacing 5 million tons of standard coal of fossil energy.

The patented technical solution is to grind 95-97 parts of mulberry branches and 3-5 parts of combustion accelerant, mix them, and shape them under the conditions of a pressure of 50-250 MPa and a temperature of 70-250°C. This technology uses single woody biomass raw materials such as cassava stalks, mulberry branches, and wood scraps to press pellets into fuel. Because the internal structure of single woody biomass is relatively hard, it is easy to cause damage to the main components of the molding machine and shorten the life of the molding machine. service life.

为了实现上述目的，本发明采用了以下技术方案：一种利用桑枝发酵废弃物制备生物质颗粒燃料的方法，以桑枝废弃物和木本植物剩余物为原料，包括以下步骤：In order to achieve the above object, the present invention adopts the following technical solutions: a method for preparing biomass pellet fuel by using mulberry branch fermentation waste, using mulberry branch waste and woody plant residues as raw materials, comprising the following steps:
1）粉碎：将桑枝发酵废弃物粉碎至 1~3mm，木本植物剩余物粉碎至3~6mm；1) Crushing: crush the fermented waste of mulberry branches to 1~3mm, and crush the residues of woody plants to 3~6mm;
2）搅拌混合：按照重量份数比，将步骤1）得到桑枝发酵废弃物粉末5~40份和木本植物剩余物粉末60~95份搅拌混合均匀；2) Stirring and mixing: According to the ratio of parts by weight, 5-40 parts of mulberry branch fermentation waste powder obtained in step 1) and 60-95 parts of woody plant residue powder are stirred and mixed evenly;
3）干燥：将步骤2）混合均匀的物料加热干燥至含水率为14~25%；其中优选含水率为16±0.5 %；3) Drying: heat and dry the homogeneously mixed material in step 2) until the moisture content is 14~25%; the preferred moisture content is 16±0.5%;
4）压制成型：将步骤3）干燥好的物料送入压辊式环模成型机压制成无孔实心圆柱型、密度在1.0~1.4 g/cm3的生物质颗粒燃料。4) Compression forming: Send the dried material in step 3) into a roller ring die forming machine to form a non-porous solid cylindrical biomass pellet fuel with a density of 1.0~1.4 g/cm 3 .
作为本发明的进一步限定，所述的桑枝发酵废弃物其组分包括：桑枝80~90份、木薯酒精废渣7~15份、氧化钙1~5份、硫酸钙0.5~3份。其优选方案为桑枝85重量份、木薯酒精废渣12重量份、氧化钙2重量份以及硫酸钙1重量份。以上所用到的桑枝发酵废弃物可以是桑枝屑为主要成分、用来栽培各种菌菇后的废弃物。As a further limitation of the present invention, the components of the mulberry branch fermentation waste include: 80-90 parts of mulberry branch, 7-15 parts of cassava alcohol waste residue, 1-5 parts of calcium oxide, and 0.5-3 parts of calcium sulfate. Its preferred scheme is 85 parts by weight of mulberry branches, 12 parts by weight of cassava alcohol waste residue, 2 parts by weight of calcium oxide and 1 part by weight of calcium sulfate. The mulberry branch fermentation waste used above can be the waste after the mulberry branch scraps are used as the main component to cultivate various mushrooms.
作为本发明的进一步限定，其特征在于，所述的木本植物剩余物为桑枝、桉树皮、松木屑中的一种或是它们的组合物。生物质颗粒燃料的优选原料组成包括12~15重量份桑枝发酵废弃物、80~85重量份的桉树皮和5~8重量份的松木屑。As a further limitation of the present invention, it is characterized in that the woody plant residue is one of mulberry branches, eucalyptus bark, and pine sawdust or a combination thereof. The preferred raw material composition of the biomass granular fuel includes 12-15 parts by weight of mulberry branch fermentation waste, 80-85 parts by weight of eucalyptus bark and 5-8 parts by weight of pine wood chips.

A solid cylinder with a diameter of 8 mm and a length of 30 to 40 mm is preferred. The particle size of biomass wood pellet fuel directly affects the burning speed and the thickness of the calcination zone. In order to ensure sufficient residence time of the material in the calcination zone, the particle size of the fuel has a certain ratio to the particle size of the material. The particle size of the fuel is too small and the combustion speed is too fast, so that the high temperature zone is too concentrated, the residence time of the raw material in the high temperature zone is too short, the main reaction during firing is too late, and the firing quality is affected, that is, the combustion calorific value, combustion rate and thermal efficiency are reduced. , Ash increased. The particle size of the fuel is not easy to be too large, which will slow down the combustion speed, elongate the calcination zone, and the firepower will not be concentrated, which will reduce the temperature of the calcination zone.

It has better fluidity and viscosity during the process, and plays a good role in lubrication and bonding. It can be filled into the gaps of raw materials, and the components of raw materials are closely combined to effectively improve the molding rate and product quality of pellet fuel. density and durability. In addition, the mulberry branch fermentation waste contains a small amount of calcium oxide and calcium sulfate, which can react with Si, K and other elements during the combustion process to form new compounds, which can increase the softening temperature of ash deposits and thus have an anti-slagging effect. At the same time, the present invention mixes and floats woody plant residues with a high combustion calorific value in an appropriate mass portion, so that the combustion calorific value of the biomass particle fuel product meets the use standard.
