Description

[根据细则37.2由ISA制定的发明名称]　多燃烧器卧式煤分解设备 技术领域
本发明属于煤物质综合利用、节能减排技术领域，具体涉及一种煤物质多燃烧器卧式分离设备。
背景技术
在公知技术中，有利用煤制煤气的，有利用煤制天然气的，还有利用煤进行高温、中温、低温炼焦、制气的，但上述工艺方法不是将煤粉团成块的，就是要筛选块料，原料成本增加，或所产气热值不高，附加值不大，经济效益和社会效益不显著。炉的加热方式可分为外热式、内热式及内热外热混合式。外热式炉的加热介质与原料不直接接触，热量由炉壁传入；内热式炉的加热介质与原料直接接触，因加热介质的不同而有固体热载体法和气体热载体法两种。
内热式气体热载体法是 工业上已采用的典型方法。此法采用气体热载体内热式垂直连续炉，即从上而下包括干燥段、 分解 段和冷却段三部分。煤低温 分解 褐煤或由褐煤压制成的型块（约25～60mm）由上而下移动，与燃烧气逆流直接接触受热。炉顶原料的含水量约15％时，在干燥段脱除水分至 1.0％以下，逆流而上的约250℃热气体冷至80～100℃。干燥后原料在 分解 段被600～700℃不含氧的燃烧气加热至约500℃，发生热分解；热气体冷至约250℃，生成的半焦进入冷却段被冷气体冷却。半焦排出后进一步用水和空气冷却。从 分解 段逸出的挥发物经过冷凝、冷却等步骤，得到焦油和 热解水。德国、美国、苏联、捷克斯洛伐克、新西兰和日本都曾建有此类炉型。
内热式固体热载体法是固体热载体内热式的典型方法。原料为褐煤、非粘结性煤、弱粘结性煤以及油页岩。20世纪50年代，在联邦德国多尔斯滕建有一套处理能力为10t/h煤的中间试验装置，使用的热载体是固体颗粒（小瓷球、砂子或半焦）。由于过程产品气体不含废气，因此后处理系统的设备尺寸较小,煤气热值较高，可达20.5～40.6MJ/m3。此法由于温差大，颗粒小，传热极快，因此具有很大的处理能力。所得液体产品较多、加工高挥发分煤时，产率可达30％。L-R法工艺流程煤低温 分解是首先将初步预热的小块原料煤，同来自分离器的热半焦在混合器内混合，发生热分解作用。然后落入缓冲器内，停留一定时间，完成热分解。从缓冲器出来的半焦进入提升管底部，由热空气提送，同时在提升管中烧去其中的残碳，使温度升高，然后进入分离器内进行气固分离。半焦再返回混合器，如此循环。从混合器逸出的挥发物，经除尘、冷凝和冷却、回收油类，得到热值较高的煤气。
 技术问题
当前，常用的煤分解设备主要是有两种，有一种是竖窑结构，该结构燃烧烟气和煤产生的可燃性气体，使得可燃气的纯度低，附加值低，还有部分排出，造成资源的大量浪费和环境的污染。另一种立窑是煤块放置在带孔的隔板上，煤块上方有加热器，因隔板上的煤块有一定的堆积厚度，不能被均匀加热、分解，需要用被分解的气体循环加热、分解，更为重要的是，因为煤隔板上循环通气孔的大量存在，煤粉会从通气孔漏下来，所以煤粉需要进入立窑时先需要将煤粉加工成煤团，所以煤粉不能直接用于窑体分离，这就相应地增加了煤粉分解的成本，降低了经济效益。
技术解决方案
本发明为解决上述工艺及方法中存在的问题，提出了一种能直接将煤粉物质分离、提高其综合利用价值、节能减排，从而提高经济效益和社会效益的煤物质多燃烧器卧式分离设备。
一种煤物质多燃烧器卧式分离设备，包括一个横向设置的密封回转窑体，所述回转窑体包括一个进料口、出料口，所述回转窑体内沿窑体方向设置密排的多个燃烧器，所述密排的多个燃烧器一侧对应设置密排的多个燃气进气管和与燃气进气管平行的密排的多个空气进气管，所述燃气进气管与对应的燃烧器连通，所述的密排空气进气管与对应的燃烧器连通，所述密排的多个燃烧器的另一侧设置对应的多个密排散热管，所述密排的多个燃烧器与对应的密排散热管相连通，所述密排的多个燃烧器内对应设置多个点火器，所述密排的多个燃烧器、散热管、燃气进气管、空气进气管与回转窑体内壁之间形成煤物质推进分离通道，所述煤物质推进分离通道与所述进料口和出料口连通，所述回转窑体上进料口所在端设置煤分离出的燃气、焦油气收集管，所述煤分离燃气、焦油气收集管与煤物质推进分离通道连通，另一端与燃气除尘液化机构连接，所述密排散热管与焰气汇集管连通，所述焰气汇集管伸出回转窑外。
所述密排燃气进气管、空气进气管与出料口在窑尾上设置支撑旋转滑环，所述燃气进气管、空气进气管与支撑旋转滑环活动连接，所述支撑旋转滑环与窑尾相对旋转、滑动。
所述回转窑体内壁上设置煤粉扬起推进机构。
所述煤粉扬起推进机构是大量设置在回转窑体内壁上的扬板。
所述密排散热管、密排燃气进气管、密排空气进气管与回转窑体内壁之间设置管道支撑机构。
所述焰气汇集管远离密排散热管的一端与煤粉干燥预热机构连接。
 有益效果
由于本发明将常用的竖立分解窑形式改成基本水平的横向密闭回转窑体，回转窑体内的燃气进气管、空气进气管将空气和燃气带入密排的燃烧器，点火器点燃混合气，燃烧后的焰气源源不断地进入密排散热管，产生的大量的热通过密排散热管壁传导、辐射到燃烧器、散热管与回转窑体内壁之间形成的空腔内的煤粉上，被回转窑体内壁上设置的煤粉扬起推进机构扬起的煤粉充分地吸收，煤粉升温分解，就在煤物质推进分离通道内分解成燃气、焦油气和热值较高的煤，燃气和焦油气通过所述煤分离燃气、焦油气收集管与回转窑外的燃气除尘液化机构连接，将分解到的燃气、焦油气收集、除尘、分离、加压液化。所述密排空气管、密排燃气进气管以密排形式设置，便于充分吸收高温已分解煤粉内的热，一方面充分利用了系统产生的热能，同时使得煤粉的温度慢慢降低，最终便于贮存和利用。所述密排散热管、密排空气管、密排燃气进气管与回转窑体内壁之间设置管道支撑机构，进一步提高燃烧器与回转窑体之间结合的可靠性和稳定性；所述焰气汇集管远离密排散热管的一端与煤粉干燥预热机构连接，保证通过焰气汇集管后的焰气内尚存大量的热能被煤粉预吸收干燥升温，提高了能源的利用率，同时也大大提高了进入回转窑体前的煤粉的温度，降低了煤粉的含水量。本发明可将粉煤快速高效地分解分离，充分节约和利用了能源，大大地提高了煤资源的利用率和利用水平，将为整个社会带来了大量的经济效益和社会效益。

密排的燃气进气管 5 和密排的空气进气管 6 的设置便于充分吸收高温煤粉内的热，一方面充分利用了系统产生的热能，同时使得煤粉的温度慢慢降低，最终便于贮存和利用。
所述回转窑体 1 内壁上设置煤粉扬起推进机构 13 ，大量设置在回转窑体内壁 1 上的扬板一方面推进煤粉向前运动，另一方面将煤粉在旋转推进中更便于均匀吸收大量的热。
所述密排散热管 7 、密排燃气进气管 5 、密排空气进气管 6 与回转窑体 1 内壁之间设置管道支撑机构 14 ，进一步提高燃烧器与回转窑体之间结合的可靠性和稳定性。
所述焰气汇集管 12 远离密排散热管 7 的一端通过管道 15 与煤粉干燥预热机构 16 连接，保证通过焰气汇集管 12 后的焰气内尚存大量的热能被煤粉预吸收、被干燥，提高能源的利用率，同时也大大提高了进入回转窑体 1 前的煤粉的温度。
