棕榈空果串介绍

一、 概述在东南亚生产棕榈油是一个重要的产业。在棕榈成熟后果实从茎上分离，留下的空果串（EFB）成为了一种废料。每年都会产生几百万吨的EFB，而研究利用这种废料的可能性也在不断的进行。大部分EFB的处理都是燃烧后将灰当作植物的肥料，但是燃烧会带来很大的环境污染所以就要寻找其它的处理办法。EFB在它的薄壁组织中含有维管束，这种材料很有弹性且密度很低。一些研究指出可以利用EFB进行造纸，并且EFB一种非木材纤维原料，作为制浆造纸工业的一种原材料具有很好的潜力。另外，EFB还可以作为锅炉的燃料进行使用。许多实验室对EFB的制浆和造纸的性能进行了大量研究。结果表明由于EFB自身的特点，例如可大量获得且供应稳定，木素含量低而纤维及纤维素含量高，其性能与阔叶木相似，它的形态有利于造纸等，使得它具有作为制浆造纸原料的良好潜力。并且实验室的手抄纸有很好的结合强度和纸页性能。然而，这些发现仍未被商业化利用。本公司在总结了实验室大量研究的基础上，开发出了碱法、CTMP以及半化学法对EFB进行制浆的工艺技术，利用这些工艺技术生产的浆可以抄造各种文化用纸，还可以与旧瓦楞纸（OCC）进行混合配抄，生产瓦楞纸板产品。本公司可以提供制浆造纸工厂的设计及其设备选型的服务，并且可以在建厂过程中提供各种技术支持。竭诚的希望我们的服务能为当地的资源利用和环境保护做出贡献。二、 备料工艺流程空果串输送机螺旋挤压机皮带输送机 切断机储料仓锅炉燃烧 螺旋挤压机是对棕榈空果串挤压的关键设备之一,挤压的效果好坏将直接影响后道工序的切断加工.螺旋挤压机的工作原理:棕榈空果串由滤鼓上方一端的进料口进入滤鼓,在螺旋且具有一定的压缩比的螺旋主轴的挤压作用下,将含有6580%水份的棕榈空果串挤压脱水至含有4050%的水份的扁状空果串,由出料口送入切断机进行切削加工。挤出的滤液经滤鼓进入接水槽从出口流出,经收集槽进行油水分离、沉淀过滤，滤油回收滤水送水处理进行循环利用。螺旋主轴采用整体离心浇铸，改变以往钢板焊接使用寿命短，经常需要焊接的缺点，有效地保证了设备地正常运行。 Palm oil production is an important business in Southeast Asia. After harvesting the fruits are separated from stem leaving the empty fruit bunches (EFB) as a waste material. Several million tons of EFB are obtained each year in the region and different possibilities to use this material have been investigated.Most of the EFB is today incinerated and the ash is brought back to the plantations as fertilizer. The incineration process results in severe air pollution and alternative uses for EFB are investigated. The EFB consists of vascular bundles embedded in parenchyma tissue. The material is quite springy and flexible and has very low bulk density. Some studies have been carried out investigating the possibilities to produce papermaking fibers from this material, and EFB, a non-wood fiber source, has a good potential to be used as a raw material for pulp and paper industries.A lot laboratories work have been done by researchers on utilization of EFB for pulp and paper. The results indicate that EFB possess great potential as pulp and paper raw material due to its availability in big quantity and continuous supply, its chemically low lignin and high cellulose content, its high fiber content, its resemblance to hardwood fibers, which its morphology is favorable for papermaking, and lab handsheet has good bonding strength and paper properties. Anyhow, none of these discoveries
