Description

一种热值高的生物质燃料及其制备方法
技术领域
本发明涉及一种热值高的生物质燃料及其制备方法。
背景技术
普通生物质颗粒燃料是由锯末、花生皮及稻壳制成，这种生物颗粒燃料由于颗粒较大，并且其含水率高，从而很难进行引燃，并且由于其颗粒较大，在燃烧过程中会燃烧不充分，且其本身的热值低，从而导致不仅燃烧产生的热量不大，而且灰分高，燃烧后残留的污染物较多，最终燃烧时为了达到所需热量需要大量的燃料供给，同时燃烧后还需要处理残留物对环境的影响，最终影响了其应用范围。因此本行业亟需一种能燃烧充分、热值高、且残留物极少的生物质燃料。
发明内容
针对上述现有技术存在的问题，本发明提供一种热值高的生物质燃料及其制备方法，其燃烧的热值高，同时还具有燃烧充分且残留物极少，从而扩大其适用范围。
为了实现上述目的，本发明采用的技术方案是：一种热值高的生物质燃料，按照重量份数组分为：花生壳3～9份、玉米秸秆10～15份、水稻秸秆5～13份、甘蔗渣5～9份、棉粕7～13份、松木锯末6～11份、蓖麻秸秆3～8份、豆荚7～12份、助燃剂1～2份。
进一步，按照重量份数具体组分为：花生壳6份、玉米秸秆12份、水稻秸秆9份、甘蔗渣7份、棉粕10份、松木锯末8份、蓖麻秸秆6份、豆荚9份、助燃剂1份。
进一步，所述助燃剂由高锰酸钾与氯酸钾按1:1的比例混合制成。
一种制备热值高的生物质燃料的方法，具体步骤为：
A、按重量取出花生壳、玉米秸秆、水稻秸秆、甘蔗渣、棉粕、松木锯末、蓖麻秸秆和豆荚，在不高于40℃的温度条件下进行超微粉碎处理50min，得到上述各个组分的超微粉；
B、将上述各个组分的超微粉放入60～65℃水中混合30min，然后蒸馏得到混合粉体；
C、将混合粉体置于活化炉内，通入压力为2～3Mpa的水蒸气，在400～450℃下活化处理0.8～1.5h，然后得到碳化后的粉体；
D、待碳化后粉体降至常温后将助燃剂与其混合，最终制得生物质燃料。
进一步，所述步骤A采用的超微粉碎处理为干法研磨或气流式粉碎，最终得到的粉体中90％的颗粒粒径达到300目。
与现有技术相比，本发明采用花生壳、玉米秸秆、水稻秸秆、甘蔗渣、棉粕、松木锯末、蓖麻秸秆、豆荚和助燃剂相结合方式，在燃烧时通过助燃剂能快速的进行引燃，另外由于超微粉碎其粉体粒径极低，从而增加了燃烧时与空气的接触面，进而提高燃料的充分燃烧情况，最后由于上述各种物质相互作用可有效提高燃料的热值，从而使得本发明具有较大的适用范围。
具体实施方式
下面将对本发明作进一步说明。
