具体实施方式
本发明的核心是提供了一种裂解设备，提高了传热效率，减小了资源浪费。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图1-图6，本发明实施例提供了一种裂解设备，包括裂解筒1和燃烧筒2，燃烧筒2密封套设于裂解筒1的外周，裂解筒1相对固定设置的燃烧筒2做旋转运动；裂解设备还包括返料输送机10和设置于裂解筒1内的与裂解筒1内部隔离的气体连通腔体3；气体连通腔体3与燃烧筒2连通，用于将燃烧筒2的加热气体引入气体连通腔体3中，气体连通腔体3的腔体壁用于与裂解筒1内的物料传热；裂解筒1内裂解后的固体废渣通过返料输送机10输送至燃烧筒2内。
该裂解设备工作时，有机固废通过进料装置12进入裂解筒1内，随着裂解筒1的旋转，为了保证裂解效果，裂解筒1旋转缓慢，物料在裂解筒1内沿筒壁滑落移动，此过程中，燃烧筒2中的热量通过裂解筒1的筒壁传递至裂解筒1内，物料在裂解筒1内滑落的过程中与筒壁接触传热，同时，燃烧筒2的加热气体引入到气体连通腔体3中，通过气体连通腔体3的腔体壁与物料接触传热，并且通过气体连通腔体3的腔体壁向裂解筒1内辐射热量，相比于现有的仅通过裂解筒1的筒壁对其中的物料进行加热，本申请通过气体连通腔体3的腔体壁大大增加了裂解筒1内部的传热面积，提高了传热效率和热能利用 率，更有利于裂解反应的快速进行，节省了反应时间。同时，在燃烧筒2燃烧的过程中，将裂解筒1中裂解后的固体废渣通过返料输送机10输送至燃烧筒2内进行燃烧，避免了固体废渣的直接排放，从而实现了固体废渣的回收利用，减少了资源的浪费。
进一步地，在本实施例中，裂解设备还包括锁气出料装置7，锁气出料装置7转动连通于裂解筒1的出料口，返料输送机10的两端分别与锁气出料装置7和燃烧筒2连通。工作时，裂解筒1中的固体废渣通过锁气出料装置7排出，排出后进入返料输送机10，返料输送机10将固体废渣输送至燃烧筒2中。
作为优化，在本实施例中，返料输送机10为螺旋输送机，当然，返料输送机10还可以为推料机构。
更进一步地，在本实施例中，返料输送机10的出口连通于燃烧筒2的靠近裂解筒1的出料端的位置，且燃烧筒2内设置有返料螺旋，返料螺旋的输送方向为由裂解筒1的出料端指向进料端。如此设置，使进入燃烧筒2中的固体废渣在燃烧筒2内的移动方向与裂解筒1内的物料的移动方向相反，从而进一步提高热量的利用率。当然，返料输送机10的出口还可以设置于燃烧筒2的其它位置，只要能够将固体废渣通入燃烧筒2即可。具体地，返料螺旋固定于裂解筒1的外筒壁上，随着裂解筒1的转动，返料螺旋推动固体废渣沿与裂解筒1的输送方向相反的方向在燃烧筒2中移动。
进一步地，在本实施例中，裂解设备还包括可燃气输送管路8，裂解筒1内产生的可燃气通过可燃气输送管路8连通至燃烧筒2内。即在燃烧筒2燃烧的过程中，将裂解筒1中裂解产生的可燃气可通过可燃气输送管路8输送至燃烧筒2内进行燃烧，通过裂解设备自身产生的可燃气替代部分外部能源物质，从而降低了成本。
具体地，可燃气输送管路8与锁气出料装置7连通，由于锁气出料装置7气密性较好，因此，裂解筒1产生的可燃气进入锁气出料装置7，再通过可燃气输送管路7进入燃烧筒2中。
在本实施例中，裂解设备还包括可燃气净化系统9，可燃气输送管路8与 可燃气净化系统9串联，可燃气净化系统9的可燃气出口与燃烧筒2连通。即裂解筒1中的可燃气先经过可燃气净化系统9进行净化后，再进入燃烧筒2中燃烧，保证燃烧筒2中的燃料清洁。
在本实施例中，裂解设备还包括尾气净化系统11，燃烧筒2开设有尾气排放口，尾气排放口与尾气净化系,11连通，燃烧筒2中产生的废气经过尾气净化系统9净化后排放，以达到环保要求。
在本实施例中，裂解设备还包括设置于燃烧筒2和/或裂解筒1中的温度传感器和/或压力传感器，通过温度传感器检测燃烧筒2和/或裂解筒1中的温度，通过压力传感器检测燃烧筒2和/或裂解筒1中的压力，进而根据检测的温度和压力人工或自动控制裂解反应的进行。
如图3-图6所示，在本实施例中，气体连通腔体3为一个连续的腔体结构或为多个分体的腔体结构。一个连续的腔体结构与燃烧筒2气体连通，或者多个分体的腔体结构分别与燃烧筒2气体连通，只要能够将燃烧筒2中的加热气体引入到气体连通腔体3中即可，以增大裂解筒1内的传热面积，实现物料多方向的受热。
不管气体连通腔体3是一个连续的腔体结构或者是多个分体的腔体结构，其腔体结构的形状和大小不做限制，可以是任意形状，如条形腔体结构、块状腔体结构、异形腔体结构等，还可以任意布置于裂解筒1内，如沿裂解筒1的轴向、横向等布置，只要保证物料能够在裂解筒1内流通，并通过腔体结构传热即可。
在本实施例中，气体连通腔体3和燃烧筒2通过开设于裂解筒1的筒壁的连通孔4保持气体连通。连通孔4能使燃烧筒2内的加热气体进入气体连通腔体3中，且尽量减少或避免燃烧筒2内的固体或液体物料通过连通孔4进入气体连通腔体3中，由于燃烧筒2固定设置，因此，固体或液体物料通常停留在燃烧筒2的底部，不容易进入连通孔4，而燃烧筒2中的加热气体能够扩散并对流通过连通孔4进入气体连通腔体3中，从而进一步保证了加热气体在气体连通腔体3内更好地流通进行传热。
当然，本实施例不对连通孔4的形状、大小和数量进行限定，连通孔4 可以是任意形状，如圆形、矩形、椭圆形、梅花形等，只要有利于气体通过即可，连通孔4的大小根据加热需求而定，如果加热需求大，可以设置较大的连通孔4，以保证足够的加热气体的流通，相反，则设置较小的连通孔4。连通孔4的数量同样根据加热需求设定，连通孔4的数量相对越多，气体连通腔体3内的加热气体的流通越顺畅，加热速度越快，反之则加热速度越慢，但同时要保证尽量避免燃烧筒2内的固体和液体物料进入气体连通腔体3中。
进一步地，在本实施例中，气体连通腔体3的一侧腔体壁与裂解筒1的内壁贴合固定或共用，即气体连通腔体3坐落固定于裂解筒1的内筒壁上，气体连通腔体3用于坐落的一侧腔体壁可以是独立的腔体壁，也可以与裂解筒1的内壁共用。连通孔4开设于气体连通腔体3与裂解筒1相贴合或共用的筒壁上，气体连通腔体3和燃烧筒2通过连通孔4保持气体连通。通过将气体连通腔体3坐落固定于裂解筒1的筒壁上，可以使裂解筒1内的物料在裂解筒1内沿筒壁滑落的过程中，增加与气体连通腔体3的腔体壁接触传热的机会，延缓物料移动的速度，从而进一步提高传热效率。
当然，气体连通腔体3也可以悬置于裂解筒1内，气体连通腔体3的腔体壁不与裂解筒1的内筒壁接触，而是通过支撑结构进悬空固定。相应地，气体连通腔体3通过连通管与裂解筒1的筒壁上的连通孔4连通，实现气体的连通。如此设置，物料在裂解筒1内移动的过程中，可能很少与气体连通腔体3的腔体壁接触，但通过气体连通腔3的腔体壁进行热量辐射加热，同样可以提高传热效率。
进一步地，在本实施例中，气体连通腔体3优选为一组或多组螺旋结构腔体，螺旋结构腔体沿裂解筒1的轴向螺旋延伸，螺旋结构腔体的侧壁与裂解筒1的筒壁形成螺旋物料通道5，多组螺旋结构腔体沿裂解筒1的轴向依次排布，组合形成连续的螺旋物料通道5，螺旋结构腔体内部形成螺旋的气体通道。如此设置后，螺旋结构腔体能够充分利用裂解筒1内的空间，提供了裂解筒1与燃烧筒2之间径向和轴向热对流、热传导、热辐射通道，大大增加了传热面积。工作时，物料由裂解筒1的进料端进入裂解筒1内后，随着裂解筒1的旋转，物料在螺旋物料通道5中逐渐由裂解筒1的进料端向出料端移动，物料被 旋转的螺旋结构腔体驱使自动向后移动，因此，裂解筒1可以采用水平放置的形式，不需要使进料端高于出料端倾斜设置。物料在螺旋物料通道5中移动的过程中，物料始终与螺旋结构腔体的侧壁和裂解筒1的筒壁接触传热，且延长了物料的运行路径，提高了物料在裂解筒1内的停留时间，使物料充分加热，进一步提高了传热效率，更有利于裂解反应的进行。
当然，如果气体连通腔体3不采用螺旋结构腔体，为了方便物料由进料端向出料端移动，裂解筒1的进料端高于出料端倾斜设置，利用物料自重和裂解筒1的旋转实现物料的自动移动。
如图5所示，进一步地，在本实施例中，螺旋结构腔体与裂解筒1相贴合或共用的筒壁上开设有一个或多个连通孔4，多个连通孔4沿螺旋方向布置。如果设置一个连通孔4，则利用燃烧筒2内的具有一定压力的加热气体通过该连通孔4进入螺旋结构腔体中，为了使加热气体充满螺旋结构腔体，一个连通孔4设置于螺旋结构腔体的一端，加热气体由螺旋结构腔体的一端逐渐充满整个腔体，连通孔4优选设置在螺旋结构腔体靠近出料端的一端，使加热气体的流向与物料移动的方向相反，以进一步提高传热效率。如果设置多个连通孔4，则多个连通孔4沿螺旋结构腔体的螺旋方向布置，优选地，多个连通孔4均匀分布，以进一步提高气体传热的均匀性。
进一步地，在本实施例中，螺旋结构腔体为环形螺旋结构腔体，环形螺旋结构腔体的内圈与裂解筒1的轴线之间存在径向间距。如此设置，环形螺旋结构腔体的中心部位形成贯通裂解筒1的轴向的空心区域，裂解筒1内裂解产生的气体可以更顺畅地通过空心区域进行流通。
当然，螺旋结构腔体还可以不具有空心区域，则裂解筒1内裂解产生的气体同样能够在螺旋物料通道5中进行螺旋输送，只是气体输送的路径较长。
作为优化，在本实施例中，环形螺旋结构腔体的外圈直径和内圈直径的差值大于5cm，根据加热需要以及裂解筒1内的气体输送需求确定环形螺旋结构腔体的外圈直径与内圈直径的差值。差值的确定需要保证燃烧筒2与裂解筒1之间的温差，使物料能充分裂解的同时，避免快速焦化。
作为优化，在本实施例中，螺旋结构腔体的两个侧壁之间的宽度为 1cm～100cm，宽度的大小决定了螺旋结构腔体内部的气体螺旋通道的大小，进而决定了加热量的大小和散热面积大小，以及保证热气流的对流和紊流的产生。更优选地，两个侧壁之间的宽度为50cm左右。
在本实施例中，螺旋结构腔体的螺距为等螺距或变螺距，螺距大于1cm。根据裂解筒1内不同轴向段的温度梯度和碳化需求确定螺距形式和螺距大小。
如图6所示，为了方便裂解筒1内的物料出料，在本实施例中，裂解筒1内靠近出料端的位置设置有翻料导出机构6。翻料导出机构6随裂解筒1的旋转不断将位于出料端的物料翻起并导向出料口，避免物料在出料端堆积。
作为优化，在本实施例中，翻料导出机构6包括多个沿圆周方向排布且固定于裂解筒1的内筒壁上的V形翻料板61或弧形翻料板，V形翻料板61的凹角朝向和弧形翻料板的内凹面朝向均与裂解筒1的旋转方向相同，V形翻料板61和弧形翻料板的一端均与裂解筒1的出料端内端面固定，另一端为自由端。其中，V形翻料板61由两个板组合形成V形结构。
以V形翻料板61为例进行说明，其工作原理是：随着裂解筒1的旋转，物料不断进入V形翻料板61的进口端，由于V形翻料板61的凹角朝向与裂解筒1的旋转方向相同，因此，V形翻料板61由低处向高处移动的过程中，将裂解筒1筒壁上的物料提起，使物料向出料端方向移动积聚于凹角处，随着V形翻料板61由高处向低处移动的过程中，积聚于凹角处的物料开始抛洒的同时，物料沿V形翻料板61靠近出料端的一个板移动至出料端的出料口，实现了物料的翻料和导出。
同理地，弧形翻料板在由低处向高处移动的过程中，将裂解筒1的筒壁上的物料移动至内凹面处，弧形翻料板在由高处向低处移动的过程中，将内凹面处的物料抛洒并沿弧形翻料板的板面导出至出料口。
进一步地，在本实施例中，V形翻料板61的凹角处挡板还设置有挡板62，用于兜料，通过挡板62更好地积聚物料，将物料提成至高处进行抛洒。同理地，弧形翻料板的内凹处也设置有挡板62，用于兜料。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
