  经济的快速发展离不开能源,而传统化石能源石油、天然气和煤炭的紧缺问题日益严重。生物质能作为第四大能源,以其可再生、零碳排放等特点,成为新能源中发展潜力较大的一种能源。
  The rapid development of economy can not be separated from energy, while the shortage of traditional fossil energy such as oil, natural gas and coal is becoming more and more serious. As the fourth largest energy source, biomass energy has become one of the most promising new energy sources because of its renewable and zero carbon emissions.
  生物质颗粒燃料,又称生物质成型燃料(BiomassMouldingFuel,简称“BMF")是应用农林废弃物(如秸秆、锯末、甘蔗渣、稻糠等)作为原材料,经过粉碎、混合、挤压、烘干等工艺,制成各种成型(如颗粒状)的,可直接燃烧的一种新型清洁燃料。
  Biomass Moulding Fuel (BMF) is a new type of clean fuel which can be directly burned by using agricultural and forestry wastes (such as straw, sawdust, bagasse, rice chaff) as raw materials, through grinding, mixing, extrusion, drying and other processes.
  生物质木屑颗粒燃料生产设备,其以木屑为原料制备生物质木屑颗粒燃料,其生产方法过程简单,适合产业化生产,制备的生物质木屑颗粒燃料热值、燃烧率和热效率高。
  Biomass sawdust pellet fuel production equipment, which uses sawdust as raw material to prepare biomass sawdust pellet fuel, its production process is simple, suitable for industrial production, the prepared biomass sawdust pellet fuel calorific value, combustion rate and thermal efficiency.
  生物质木屑颗粒燃料生产设备,包括依次连接的锯末粉碎机、滚筒式烘干机和挤压成型颗粒机,在滚筒式烘干机和挤压成型颗粒机之间设有屯料房,用于中转木屑原料和检测木屑原料的水分含量。木屑原料经锯末粉碎机粉碎后,被输送至滚筒式烘干机进行烘干以控制其水分含量,再输送至颗粒机挤压成型,制得生物质木屑颗粒燃料。
  Biomass sawdust granular fuel production equipment, including sawdust mill, drum dryer and extrusion granulator connected in turn, is equipped with a stuffing room between drum dryer and extrusion granulator for transferring sawdust raw materials and detecting moisture content of sawdust raw materials. The sawdust raw materials are crushed by sawdust mill, then transported to drum dryer for drying to control its moisture content, and then transported to granulator for extrusion to produce biomass sawdust granular fuel.
  木屑原料的水分含量对挤压成型的压缩比产生较大影响,水分含量过高或过低,则难以获得较为理想的压缩比,从而影响生物质木屑颗粒燃料的燃烧热值、燃烧率和热效率。为保证木屑原料的水分含量控制良好,若太过干燥则需要加入湿度较大的木屑进行混合;若湿度太高,还需进一步干燥。
  The moisture content of sawdust raw materials has a great influence on the compression ratio of extrusion moulding. If the moisture content is too high or too low, it will be difficult to obtain an ideal compression ratio, thus affecting the combustion calorific value, combustion rate and thermal efficiency of biomass sawdust granular fuel. In order to ensure that the moisture content of sawdust raw materials is well controlled, if it is too dry, sawdust with higher humidity should be added to mix; if the humidity is too high, further drying is needed.
  为防止屯料房中的木屑原料四处飞扬,屯料房顶部设有除尘器。
  In order to prevent the sawdust materials from flying around, a dust collector is installed on the top of the stuffing house.
  在锯末粉碎机前设有振动筛,包括筛网和位于筛网下方的集料仓,集料仓通过输送带直接与锯末粉碎机的出料口连接,分筛后筛网上的大颗木屑原料通过输送带输入锯末粉碎机的进料口。
  In front of the sawdust crusher, there is a vibrating screen, including a screen and an aggregate bin under the screen. The aggregate bin is directly connected with the outlet of the sawdust crusher through a conveyor belt. After screening, large sawdust materials on the screen are fed into the inlet and outlet of the sawdust crusher through a conveyor belt.
  木屑原料粉碎过程为:将混合后的木屑原料运送至振动筛,振动筛筛分出的大颗木屑原料运送至锯末粉碎机进行粉碎,并经锯末粉碎机的出料口流入滚筒式烘干机;振动筛分筛后,通过筛网而聚集于集料仓的木屑,其粒径已满足生产要求,不需要进一步粉碎,直接运送至锯末粉碎机的出料口,与经粉碎的木屑原料一起流入滚筒式烘干机。采用振动筛对木屑进行初步筛分,并将粒径合格的木屑直接运送至锯末粉碎机的出料口,从而减少锯末粉碎机的进料量,提高大颗木屑原料的粉碎质量,提高生产效率,节约能耗。
  The crushing process of wood chips raw materials is as follows: the mixed wood chips raw materials are transported to the vibrating screen, the large wood chips screened by the vibrating screen are transported to the sawdust crusher for crushing, and flow into the drum dryer through the outlet of the sawdust crusher; after the vibrating screen is screened, the wood chips gathered in the aggregate bin through the screen screen, whose particle size has met the production requirements and need not further crushing, and are directly transported. The material is sent to the outlet of the sawdust crusher and flowed into the drum dryer together with the crushed wood chips. Vibrating screen is used to screen wood chips preliminarily, and the wood chips with qualified particle size are directly transported to the outlet of sawdust crusher, so as to reduce the feed volume of sawdust crusher, improve the crushing quality of large wood chips raw materials, improve production efficiency and save energy consumption.
  其中,筛网通过振动轴与电机连接。筛网上部设有旋风除尘器,防止筛网上的木屑颗粒四处飞扬。筛网可拆卸地安装于集料仓上部,筛网上设有直径为0. 05-2mm的通孔或边长为0. 05-2mm的方型孔。生物质木屑原料的粒度直接影响到燃烧速度和锻烧带的厚度,为了生物质木屑颗粒燃料的燃烧热值、热效率,需要对木屑原料的粒径进行严格的控制。筛网可拆卸地安装,可依据不同木屑原料的粒径控制要求进行更换筛网。
  The screen is connected with the motor through a vibration shaft. A cyclone dust collector is installed at the upper part of the screen to prevent sawdust particles from flying around. The screen mesh can be disassembled and installed on the upper part of the aggregate bin. The screen mesh has a through hole with a diameter of 0.05-2 mm or a square hole with a side length of 0.05-2 mm. The particle size of biomass sawdust directly affects the burning speed and the thickness of the burning zone. In order to achieve the burning calorific value and thermal efficiency of biomass sawdust granular fuel, it is necessary to strictly control the particle size of biomass sawdust. The screen can be disassembled and installed, and the screen can be replaced according to the particle size control requirements of different sawdust raw materials.
