Description

工业连续化塑料裂解器 技术领域
本发明为一种通过实现工业连续生产的塑料裂解器。
背景技术
此前， 申请人已研制了塑料连续裂解的工艺及设备， 该工艺及设备中首 创了采用了固态载热体对塑料进行加热的方法，不仅成功地解决塑料在裂解 过程中的结焦等问题， 也实现了塑料连续裂解的工业化生产问题。但是， 在 该技术中， 固态载热体的返回及再加热过程、与裂解产生的固态物的分离机 构设置在裂解腔外， 使设备本身较为复杂。
发明内容 ,
本发明的目的在于： 设计一种结构简单、 体积小、 运行成本低廉的塑料 连续裂解器。
本发明的技术方案包括外筒体及内筒体， 内筒体的两端均与外筒体相 通， 外筒体及内筒体中的至少一个装有加热机构， 外筒体主体内壁上固定螺 旋带， 内筒体设置有与外筒体送料方向相反的输送机构， 内筒体的入口端设 置与外筒体之间的固态热载体导入机构；外筒体内设置有裂解生成的固态物 与固态载热体的分离机构； 外筒体上有油气出口及固态生成物出口。
对于本发明的结构， 可根据需要采用外筒体或内筒体作为裂解腔， 而另 一个作为将固态热载体返回的腔体， 但从被输送物的体积等方面考虑， 一般 将外筒体用于裂解， 而将内筒体用于送返固态载热体。 同时， 由于两个腔体 相通，在固态热载体返回时可以同时受热而提高其温度以满足裂解反应对温 度的要求。 这样， 固态热载体便在筒体内形成循环， 不仅使其结构简化， 并 减少占用空间， 而且， 固态热载体在筒体内循环没有热能的损失，' 使设备的 运行成本大大降低。
在本发明中， 内筒体中固态载热体的输送可通过多种方式实现， 如将内 筒体设计为倾斜的转筒； 或在水平的固定的内筒体中安装螺杆； 还可以将内 筒体设计为转筒， 在其内壁上固定螺旋带， 使固态载热体随内筒体的转动而 由一端送至另一端。 .
'将固态载热体或固态载热体与原料的混合物由外筒体送入内筒体的结 构有多种方式， 当内筒体倾斜时， 其低端可为其入口端； 当内筒体入口端较 高时， 也可以另外设置提升机构。提升机构还可以直接通过内筒体与其内壁 上的螺旋带实现， 即可以使内筒体与其中的螺旋带形成抄斗， 即使内筒体的 端部与螺旋带形成螺旋面，而螺旋面的端部与内筒体以及内侧的螺旋带之间 形成向周向开口的抄斗。
为补充固态载热体在裂解反应中失去的热量， 使其能够满足再次反应的 要求， 可以直接釆用在筒体内的设置较高温度的方法实现， 但为保证其吸收 足够的热量， 且加热成本较低， 应在外筒体及内筒体中分别设置加热机构， 内筒体中的加热机构可以在其筒壁上，也可以沿内筒体的轴向将其设置在内 筒体的中部。 此时， 内筒体中的加热机构可采用一管体， 它与内筒体连为一 体， 加热机构的两端穿出外筒体与驱动机构连接。
要实现裂解反应后固态生成物与固态载热体的分离， 一般是通过在筒体 内设置筛网实现的， 当内筒体作为送返固态载热体的通道时， 应将内筒体的 入口端的固态热载体导入机构设置于筛网上方。而且， 为方便同时输送分离 出的固态生成物， 本发明将筛网设计为筒状， 其外端有挡板， 防止固态载热 体流至筛网外； 筛网外壁与外筒体之间有将固态生成物送至其出口的螺旋 带， 此时， 将内筒体入口端的置于筛网内。
结合本发明中塑料的反应过程以及内筒体的结构， 本发明外将裂解产生 的油气的出口设计在靠近外筒体的原料入口端。
本发明的具体结构可采用以下方式： 它包括转动的外筒及内筒体， 外筒 体两端与其外侧的外壳之间通过动密封连接，它们之间形成带有热载体进出 口的加热腔； 外筒体两端通过动密封与封头连接； 内筒体中的加热管通过螺 旋带与内筒体连接， 加热管穿出封头并与封头通过动密封连接。
本发明中还将内筒体的前端口与外筒体的原料入口对应， 以便使原料及 时得到热量而发生反应。
基于传动的需要， 外筒体两端可设置有直径较小的连接部分， 与原料入 口邻近的连接部分中对应的内筒体外壁上设置有螺旋带；其另一连接部分的 内壁上设置有螺旋带， 由此实现原料及反应生成物的顺利输送。
