Description

稻秆制本色浆的方法 技术领域
本发明涉及一种稻秆制本色浆的方法。
背景技术
据国家统计局相关统计数据，2014年全国稻谷播种面积为3031万公顷，稻谷总产量为1.72亿吨，按照农作物产量与秸秆的估算法(1公斤稻谷约产1.1公斤秸秆)可知，我国每年约有1.89亿吨的稻谷秸秆，每年的储量极其丰富。
目前稻谷秸秆的处理的主要办法有：粉碎还田、就地焚烧、生物质发电、制浆造纸等。粉碎还田影响来年的播种，加重了病虫害；生物质发电由于受到运距的影响，超出运输半径运输成本成倍的增加，发电根本不赚钱；就地焚烧严重污染环境，已被国家明令禁止。
稻谷秸秆用于制浆造纸时，一般采用碱法制浆，产生的黑液难以生物处理，且浆得率低不到50％，纤维短。
发明内容
本发明要解决的技术问题是克服现有的缺陷，提供了一种稻秆制本色浆的方法。
为了解决上述技术问题，本发明提供了如下的技术方案：
稻秆制本色浆的方法，包括如下步骤：
(1)将稻秆切成料段；
(2)料段先送汽蒸仓预蒸，再送入连蒸器进行蒸煮，蒸煮时按料段重量计加入1.5～2％的氢氧化钾，1.2～1.5％的亚硫酸铵，1.2～1.5％的三聚磷酸钠；
(3)蒸煮后的物料送双螺杆磨浆机进行搓摩分丝，得到本色浆。
进一步，步骤(1)的料段长30-40mm。
进一步，蒸煮料液比为1:5，温度为120～125℃，时间为55～60min。
进一步，蒸煮后的物料先螺旋脱水，再送双螺杆磨浆机进行搓摩分丝。
本发明的有益效果
1、成浆效率高，浆得率可达到75～80％。
2、纤维质量好，纤维平均长度达3.26um，长宽比值大。
3、系统产生的废水b/c比值高，可达到0.5左右，极易生化，水处理可采用生物处理的办法，为造纸零排放指明了方向。
4、工艺流程简单，制浆成本低。同传统化学制浆相比可节省成本1/3左右。
具体实施方式
以下对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
实施例1
1、将全植株稻谷杆，用切草机(厂家：章丘市托尼机械制造有限公司型号：QC50)切断成30～40mm长的料段，再用圆筒筛(厂家：章丘市托尼机械制造有限公司型号YTS800：)去除杂质和细屑后备用。
2、将备好的原料(料段)用皮带输送机(厂家：丹东奥美轻工机械有限公司型号：S650)送至汽蒸仓(厂家：型号：)进行预蒸(常压，时间1-10min)，再经料塞螺旋(厂家：丹东奥美轻工机械有限公司型号：QZC25)输送至连蒸器(厂家：天津中轻机械有限公司型号：FD150)进行连续蒸煮，在蒸煮过程中按料段重量计加入1.5～2％的氢氧化钾、1.2～1.5％的亚硫酸铵和1.2～1.5％的三聚磷酸钠，料液比为1：5，温度为120～125℃， 时间为55～60min。
3、蒸煮好的物料送至螺旋脱水机(厂家：江苏金沃机械有限公司型号：TSL480)进行脱水，脱水后的物料进入双螺杆磨浆机(厂家：江苏金沃机械有限公司型号：TSP240)进行搓摩分丝，制得本色浆。
4、将本色浆送入高浓磨浆机(厂家：吉林市景皓机械制造有限公司型号：TDX1100)进行高浓打浆，磨后经4台挤浆机(厂家：丹东奥美轻工机械有限公司型号：AOM800)逆式洗涤后，进入浆池消遣，消遣后，浆经高浓除渣、筛选后上抄纸机。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
