  經濟的快速發展離不開能源,而傳統化石能源石油、天然氣和煤炭的緊缺問題日益嚴重。生物質能作為第四大能源,以其可再生、零碳排放等特點,成為新能源中發展潛力較大的一種能源。
  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.
  生物質顆粒燃料,又稱生物質成型燃料(BiomassMouldingFuel,簡稱“BMF")是應用農林廢棄物(如秸稈、鋸末、甘蔗渣、稻糠等)作為原材料,經過粉碎、混合、擠壓、烘干等工藝,制成各種成型(如顆粒狀)的,可直接燃燒的一種新型清潔燃料。
  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.
  生物質木屑顆粒燃料生產設備,其以木屑為原料制備生物質木屑顆粒燃料,其生產方法過程簡單,適合產業化生產,制備的生物質木屑顆粒燃料熱值、燃燒率和熱效率高。
  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.
  生物質木屑顆粒燃料生產設備,包括依次連接的鋸末粉碎機、滾筒式烘干機和擠壓成型顆粒機,在滾筒式烘干機和擠壓成型顆粒機之間設有屯料房,用于中轉木屑原料和檢測木屑原料的水分含量。木屑原料經鋸末粉碎機粉碎后,被輸送至滾筒式烘干機進行烘干以控制其水分含量,再輸送至顆粒機擠壓成型,制得生物質木屑顆粒燃料。
  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對擠壓成型的壓縮比產生較大影響,水分含量過高或過低,則難以獲得較為理想的壓縮比,從而影響生物質木屑顆粒燃料的燃燒熱值、燃燒率和熱效率。為保證木屑原料的水分含量控制良好,若太過干燥則需要加入濕度較大的木屑進行混合;若濕度太高,還需進一步干燥。
  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.
  為防止屯料房中的木屑原料四處飛揚,屯料房頂部設有除塵器。
  In order to prevent the sawdust materials from flying around, a dust collector is installed on the top of the stuffing house.
  在鋸末粉碎機前設有振動篩,包括篩網和位于篩網下方的集料倉,集料倉通過輸送帶直接與鋸末粉碎機的出料口連接,分篩后篩網上的大顆木屑原料通過輸送帶輸入鋸末粉碎機的進料口。
  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.
  木屑原料粉碎過程為:將混合后的木屑原料運送至振動篩,振動篩篩分出的大顆木屑原料運送至鋸末粉碎機進行粉碎,并經鋸末粉碎機的出料口流入滾筒式烘干機;振動篩分篩后,通過篩網而聚集于集料倉的木屑,其粒徑已滿足生產要求,不需要進一步粉碎,直接運送至鋸末粉碎機的出料口,與經粉碎的木屑原料一起流入滾筒式烘干機。采用振動篩對木屑進行初步篩分,并將粒徑合格的木屑直接運送至鋸末粉碎機的出料口,從而減少鋸末粉碎機的進料量,提高大顆木屑原料的粉碎質量,提高生產效率,節約能耗。
  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,篩網通過振動軸與電機連接。篩網上部設有旋風除塵器,防止篩網上的木屑顆粒四處飛揚。篩網可拆卸地安裝于集料倉上部,篩網上設有直徑為0. 05-2mm的通孔或邊長為0. 05-2mm的方型孔。生物質木屑原料的粒度直接影響到燃燒速度和鍛燒帶的厚度,為了生物質木屑顆粒燃料的燃燒熱值、熱效率,需要對木屑原料的粒徑進行嚴格的控制。篩網可拆卸地安裝,可依據不同木屑原料的粒徑控制要求進行更換篩網。
  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.
