生物质颗粒燃料及其生产方法 Biomass fuel particles and production method

技术领域 FIELD

本发明涉及生物质再生能源的应用领域,具体地说,是提供一种生物质颗粒燃料及其生产方法。 The present invention relates to the field of application of biomass renewable energy sources, in particular, it is to provide a particulate fuel material and production method Health.

背景技术 Background technique

随着全球经济的不断发展,人类对能源的需求不断增加,而石油、天燃气、煤等资源却在不断减少,开发生物质可再生能源已成各界关注的热点。 As the global economy continues to develop, the human demand for energy is increasing, while oil, natural gas, coal and other resources has been declining, the development of renewable biomass energy has become a hot spot of public attention. 世界许多国家对生物质能的开发进行了立法,并作出了相应的发展规划。 Many countries in the world for the development of biomass energy were legislative and make the appropriate development plan. 我国仍是一个农业大国,秸杆、棉子壳、林木废弃物等生物质燃料极为丰富,但长期未能得到有效利用。 China is still a large agricultural country, straw, cotton seed hulls, wood waste and other biomass fuels is extremely rich, but the long-term has not been used effectively. 进几年来,由于能源问题日益突出,开发生物质成型燃料引起了人们的关注,研究开发出了多种生物质制气炉具及成型燃料。 Into the past few years, due to the energy issues have become increasingly prominent, the development of biomass briquette attracted people's attention, research and development of a variety of biomass gas stoves and briquettes. 中国专利公开的“一种秸杆成型燃料及其制备方法”(ZL02135891.5),提供了一种是将秸杆和煤矸石按一定比例混合,挤压成型的燃料及其生产方法。 "An straw briquettes and preparation method" (ZL02135891.5) disclosed in Chinese patent, is to provide a straw and gangue by mixing, extrusion molding of the fuel and its production process. 总地来说,现有的这种生物质燃料比较适合于直接燃烧,用于制气炉具,产气效果不很理想。 In general, such a conventional biomass more suitable for direct combustion system for gas stoves, gas production effect is not very satisfactory. 而且由于采用的原料中添加有煤、煤矸石、化学粘合剂等,不是一种真正的生物质可再生燃料,不仅增加了生产成本,降低了燃料热质,而且又增加了废物的排放。 Since the raw materials used and the added coal gangue, chemical adhesive or the like, not a true renewable biomass fuel, not only increases production costs, reduce the thermal mass of the fuel, and the discharge of waste added. 中国专利申请公开的“一种农作物秸杆颗粒燃料及其制备方法”(200510106619.1),虽然未添加任何添加剂,减少了废弃物的排放,但其成型效果有待改善,燃料结构不够紧密,易松散,影响了产气效果。 Disclosed in Chinese patent application to "a particulate fuel crop straw and preparation method" (200510106619.1), while not adding any additives, the waste to reduce emissions, but its effect is molded to be improved, the structure of the fuel is not tight enough, easy to loose, affecting gas production results.

发明内容 SUMMARY

本发明的目的就在于提供一种生物质颗粒燃料,其未添加任何化学粘合剂,热质高,制气效果好。 Object of the present invention to provide a biomass fuel particles, which did not add any chemical adhesives, the high thermal mass and good gasification effect. 本发明还提供一种生产这种生物质颗粒燃料的方法。 The present invention also provides a method for producing such a fuel biomass particles.

为达到上述目的,本发明的实施方案为,一种生物质颗粒燃料,其特征在于,其由含水量在14%以下的粒度小于8mm的生物质燃料和红薯或马铃薯混合,然后压制成粒状或条状成型燃料,植物生物质燃料和红薯或马铃薯的重量配比为:生物质燃料∶红薯或马铃薯=100∶3~5,所述生物质燃料包括农作物秸杆、农作物壳、植物根茎、杂草、竹木枝叶、锯木屑、畜禽粪便中的一种或多种。 To achieve the above object, embodiments of the present invention as a raw fuel material particles, wherein the biomass fuel and the mixing of 8mm or sweet potato which is smaller than the particle size of a water content of 14% or less, and then pressed into pellets or briquette strip, and plant biomass fuels, or sweet potato weight ratio: biomass fuel: sweet potato or 100:3 = 1-5, the biomass comprises straw crops, crop shells, plant roots, heteroaryl grass, bamboo leaves, sawdust, manure in one or more.

所述粒状成型燃料的粒度为5-12mm,条状成型燃料的直径5-12mm,长度不超过50mm,含水量小于12%。 Particle size of the granule fuel is 5-12mm, the diameter of briquette strip 5-12mm, length does not exceed 50mm, a moisture content less than 12%.

所述红薯为生红薯,马铃薯为生马铃薯。 The living sweet potato, potato, potato living.

本发明的生产方法是:将植物生物质燃料干燥,至其含水量在14%以下,粉碎至粒度8mm以下的粉料,将红薯或马铃薯打成糊状,与生物质粉料混合,充分拌匀,然后压制制成粒状或短条状成型燃料。 Production method of the present invention are: the dried plant biomass fuel, to a moisture content below 14%, pulverized to a particle size of 8mm or less powder, sweet potato or potato labeled as a paste, mixed with the biomass powder, sufficiently mixed uniform, then pressed pelletized or briquette short strip.

当生物质燃料为木材、竹枝杆等硬质材料时,应粉碎至粒度小于6mm的颗粒,并用蒸气软化。 When the biomass fuel wood, hard material such as bamboo rod, should be pulverized to a particle size less than 6mm particles, and with steam to soften.

为防止燃料成品中的水份丧失以及受潮,成型燃料应采用密封包装。 To prevent the loss of fuel and water in the finished product moisture, briquette should be a sealed package.

本发明用富含植物淀粉的红薯或马铃薯代替化学粘合剂,其本身为天然碳水化合物,可使燃料成型容易,在制粒过程中,不会发生堵塞制粒机模板的现象,生产出的燃料结构更紧密,热质高,用于制气炉具,产气快,产气量大,时间长,不会增加废弃物的排放。 The present invention is rich in plant replaced with potato starch, sweet potato or chemical adhesive, which itself is a natural carbohydrate, the fuel can be easily molded, during granulation, clogging phenomenon does not occur template granulator, to produce the closer fuel mix, the high thermal mass, used to make gas stoves, gas fast, large gas, for a long time, will not increase the discharge of waste. 而且,植物淀粉可由生红薯代替,红薯价格低,原料广,相对于其它添加剂,降低了生产成本。 Further, by raw potato starch in place of a plant, sweet potato low price, wide material, relative to other additives, to reduce the production cost.
