Description

卧式废旧塑料、轮胎裂解炉 技术领域
本发明公开一种裂解炉，特别是一种卧式废旧塑料、轮胎裂解炉。
 背景技术
随着化学、化工行业的兴起，化学产品在人们日常生活中的应用越来越广泛，随之而来的就是一些化学废弃物的处理问题，如：废塑料、废轮胎等。废塑料、废轮胎等在自然界中几乎不可自然分解，因此需要人工对其进行再利用处理，因此，近来年兴起利用废塑料、废轮胎炼油及造气发电等。利用废塑料、废轮胎炼油及造气发电等均需要一个装置，就是裂解炉，现有技术中的废塑料、废轮胎炼油的裂解炉分为立式炉和卧式炉两种，但是在生产使用过程中，发现现在社会上已有的废塑料、废轮胎炼油的立式或卧式炉的缺点如下：由于废旧塑料内含有不可估计的缠绕物（诸如铁丝、钢丝），当采用立式反应釜裂解物料时，其搅拌轴容易被物料中的缠绕物缠绕，导致反应釜中途停机清障；当采用卧式反应釜时，虽然可以避免物料缠绕物的问题，当然它是节省了被裂解物料的分选工序，但是由于卧式反应釜是无搅拌装置，也便谈不上有刮壁装置功能。但是卧式反应釜是依靠釜体旋转，利用釜壁带动液体流动，因此会导致传热不均，液体流区小，还可能产生液体流动静止区，废塑料、废轮胎的裂解液体是黏性体，不管是立式炉的搅拌转速或卧式炉釜体转速通常很低，流体的移动仅能扩展至很短的距离而不足以克服流体的黏性力，导致釜体高温结焦或低温结焦现象，使热面结焦迅速。当工作(时)达60小时左右，焦层厚度可达到10-20mm，形成热阻，造成釜体变形，缩短了反应釜的安全使用期，并浪费大量能源，浪费生产工时，尤其是工人在清除结焦过程中，长时间地处于极端恶劣的粗碳黑粉尘环境工作，严重影响操作人员健康。
 发明内容
针对上述提到的现有技术中的裂解炉寿命短的缺点，本发明提供一种长寿命的裂解炉，其在反应釜内增设有刮刀，可防止反应釜结焦，从而增加裂解炉的使用寿命。
本发明解决其技术问题采用的技术方案是：一种卧式废旧塑料、轮胎裂解炉，裂解炉包括平卧的炉体，炉体下部侧面开有炉门，炉体上侧方设有烟囱，炉体内设有卧置的反应釜，反应釜一端开有进料口，另一端开有出气口，炉体内设有带动反应釜转动的动力源，反应釜内部设有螺旋形导热片，导热片上装有一个以上的刮刀和一个以上的导流搅拌器。
本发明解决其技术问题采用的技术方案进一步还包括：
所述的导热片横界面呈三角形，三角形底边贴装在反应釜内壁上，三角形顶角处固定安装有螺旋状的刮刀支撑板，刮刀支撑板与导热片平行设置，刮刀和导流搅拌器安装在刮刀支撑板上。
所述的刮刀支撑板两侧开有条形的刮刀导行槽，刮刀支撑板相对的面上的刮刀导行槽对应开设，刮刀两端为支承轴，刮刀通过两支承轴设置在刮刀导行槽内。
所述的刮刀横截面呈锚形，刮刀的长度大于从刮刀的支承轴至反应釜内壁的垂直长度。
所述的导流搅拌器呈鳍片形，导流搅拌器安装在刮刀支撑板顶部。
所述的导流搅拌器的安装角度为15°-30°。
所述的进料口和出气口开设置在反应釜的中轴线上，进料口直径大于出气口直径。
所述的动力源采用三相电机，三相电机通过皮带带动反应釜外侧的齿轮驱动反应釜转动。
所述的烟囱采用方形烟囱，边角处设有圆弧倒角，烟囱内设有一层以上的水帘装置。
本发明的有益效果是：由于本发明对废塑料、废轮胎的热裂解、催化采用了卧式旋转无轴搅拌和螺旋导热片，以及鳍式螺旋导热导流片装置，解除了缠绕物缠绕搅拌轴而需停机清障的困扰。同时也解决了现有卧式旋转反应釜，因无搅拌功能导致传热效果不明显，阻延裂解及催化时间的缺陷。尤其是本发明采用了无轴刮刀刮壁装置，利用旋转惯力及流体自压产生的随机性刮壁，加强了热传递效果，阻止了反应釜壁结焦的生成，传热总系数比现在无刮壁卧式旋转反应釜提高30%，解决了现有卧式旋转反应釜结焦迅速，焦厚甚至达到十多毫米，导致传热系数低，近似于绝热操作的难题。

 具体实施方式
本实施例为本发明优选实施方式，其他凡其原理和基本结构与本实施例相同或近似的，均在本发明保护范围之内。
本发明针对物料含有缠绕性杂物、及其提高高黏流体传热系数、减慢黏釜物结焦速度而设置。请参看附图1、附图2和附图3，本发明中的炉体为卧式圆形，炉膛采用室燃炉，热源11设于反应釜9下方，本实施例中，反应釜9为圆桶型，卧置，且可以顺逆双向旋转，炉体上侧方设有烟囱，本实施例中，烟囱呈方型圆角，烟囱内设多层水帘装置，可减少本发明排出的废气、灰尘。本实施例中，反应釜9的旋转，采用三相电机作为动力源，以皮带带动齿轮进行变速，然后驱动反应釜9旋转，本实施例中，卧式反应釜9两端的中轴线位置各开设一个工作孔，两个工作的直径不同，其中，直径较大的孔为物料进料口12，另一直径较小的孔为出气口13，出气口13可连接下一阶段的炼油设备。本发明中，反应釜9内设有横截面呈三角形的螺旋导流片5（本实施例中，三角形螺旋导流片5兼有导热器、进料带动装置和自动出渣装置三个功能），本实施例中，导流片5为空心，导流片5内含有导热油3，本实施例中导流片5呈螺旋状，三角形横截面的底边紧贴反应釜9内壁固定设置。当反应釜9向顺时针方向旋转时，导热片5作为一种进料带动装置，加速物料投入；当反应釜9向逆时针旋转时，导热片5作为一种自动出渣装置，将废料残渣自动送至设于螺旋状导流片5端点的出渣口14处将废料残渣排出，导热片5的空心三角形内注有导热油3作为传热介质，加强传热效能。在螺旋导热片5的三角尖上，延螺旋方向装有刮刀支承架4，即刮刀支撑架4与导热片5平行设置，刮刀支承架4同时可作为导热片5的辅助导热件，本实施例中，随刮刀支承架4的伸延方向开设若干导行槽7，支撑架4相对的面上的导行槽7对应设置，导行槽7作为刮刀2的导行工具。请参看附图2，本实施例中，刮刀2横截面为锚形设计，即刮刀2的横截面底部为三角形的刮刀头，刮刀头上设置有连杆，横截面整体形状类似于船上用的锚的形状。刮刀2的纵向两端分别由支承轴10挂吊于导行槽7内，刮刀2的横向长度大于从刮刀2的支承轴至反应釜9内壁的垂直长度，即可保证刮刀2时时与反应釜9内侧接触，刮刀2纵向长度与螺旋状支撑架4的螺距相同，可保证刮刀2最大范围内对反应釜9内壁的作用。本发明的刮壁方法是以刮刀2的支承轴10为摆动中心，刮刀2随反应釜9的旋转沿导行槽7滑行，随机性对反应釜9内壁进行刮壁，有效地减薄反应釜热边界层的黏釜物，防止反应釜9内壁结焦过厚，及减慢反应釜9内壁的结焦速度，同时刮刀2也作用将刀口前面贴近壁面的热流刮起，并与反应釜9中部的冷流体均匀混合，提高传热系数，节省能耗。本发明在刮刀支承架4上端，延刮刀支承架4螺旋方向装置若干横向导流鳍片6，本实施例中，导流鳍片6安装角度与支承点呈15-30°（即导流鳍片6所在平面与其支撑点处的支承架4切线之间的角度为10-30°），以此强制流体传热运动。
本发明在使用时，反应釜9向顺时针方向旋转，从进料口12处投去废料，同时，热源11对反应釜9加热；当反应釜9内的废塑料、废轮胎裂解完成后，反应釜9向逆时针方向转动，将残渣从出渣口处排出。
由于本发明对废塑料、废轮胎的热裂解、催化采用了卧式旋转无轴搅拌和螺旋导热片，以及鳍式螺旋导热导流片装置，解除了缠绕物缠绕搅拌轴而需停机清障的困扰。同时也解决了现有卧式旋转反应釜，因无搅拌功能导致传热效果不明显，阻延裂解及催化时间的缺陷。尤其是本发明采用了无轴刮刀刮壁装置，利用旋转惯力及流体自压产生的随机性刮壁，加强了热传递效果，阻止了反应釜壁结焦的生成，传热总系数比现在无刮壁卧式旋转反应釜提高30%，解决了现有卧式旋转反应釜结焦迅速，焦厚甚至达到十多毫米，导致传热系数低，近似于绝热操作的难题。
