Description

一种低阶煤烘干热解一体化提质处理工艺装备 技术领域
本发明涉及一种煤化工技术装备的技术领域，尤其涉及一种用于低阶煤提质处理及电厂煤的洁净燃烧的低阶煤烘干热解一体化提质处理工艺装备。
背景技术
低阶煤是指煤化程度比较低的煤，主要分为褐煤和次烟煤，具有高挥发分、高活性、高水分等特点，使得低阶煤不便于远距离运输，而低阶煤由于热值低，直接燃烧不仅浪费大量能源、燃烧产物中含有的粉尘、硫氧化物、氮氧化物、烃和一氧化碳等有害气体，排放到大气中造成严重的大气污染。当前危及到停业停课的雾霾，与低阶煤的直接燃烧形成因果关系。随着对能源需求的不断增加和对环保要求的不断提高，低阶煤提质处理成为社会需求，各种煤热解技术得以较快发展。热解是指煤在隔绝空气条件下持续加热至较高温度时，所发生的一系列物理变化和化学反应，最终得到焦油、煤气和半焦等产物。
现行技术用于工业化热解低阶煤的方法主要有立式炭化炉热裂解，该技术要求原煤粒度较大，适用性差；产出周期长，处理能力低，焦油产量低，煤气热值低。
近期进入实验和中试的回转式热解炉，将低阶煤的中水分烘干和热解制气分在两个回转炉中，而且是外热式间接加热，热效率低，温度上升困难，进料口容易结焦堵塞。传动和支承部件全部放在高温加热筒上，热变形大，热损失 大，通常还需加较厚的保温材料，工艺流程长，热解余热不能有效利用。

本实施方式的多个热解导料叶片108、多个烘干导料叶片1113及多个反螺旋叶片1114相对于轴向倾斜，使内筒体101与外筒体111转动时，带动原 料作轴向位移。多个烘干导料叶片1113与多个反螺旋叶片1114的倾斜方向不同，多个烘干导料叶片1113与多个反螺旋叶片1114可带动原料的位移方向相反。
本实施方式的环向导料锁风装置14及环向出料锁风装置15达到锁风导料作用，保证热解过程中于无氧及缺氧状况下进行，提高热解产率。环向导料锁风装置14的锁风球1413及环向出料锁风装置15的锁风球1513的数量应能保证环向导料锁风装置14及环向出料锁风装置15随著外筒体111和内筒体101旋转至任何位置，环向导料锁风装置14的锁风球1413及环向出料锁风装置15的锁风球1513能分别压住环向导料锁风装置14的锁风阀口1412及环向出料锁风装置15的锁风阀口1512。环向导料锁风装置14的旁路封盖1414及环向出料锁风装置15的旁路封盖1514分别用于转动过程中过渡承接环向导料锁风装置14的锁风球1413及环向出料锁风装置15的锁风球1513，环向导料锁风装置14的环形导料管路141及环向出料锁风装置15的环形出料管路151畅通，另于安装维修时容易装取环向导料锁风装置14的锁风球1413及环向出料锁风装置15的锁风球1513。
