Description

两步碳化器
本发明总的来说涉及一种碳化器或热解器，尤其涉及一种两步碳化器。
碳化器或热解器是一种将燃料(例如煤)中的挥发性物质分离而产生气体、液体焦油和油类以及主要含碳的炭的装置。在七十年代，FMC公司研究出一种称作COED的方法，该法使煤热解产生含有H2、CO、CH4的气体以及用于生产汽油的液体产物。该方法是对早先的称为FormCoke方法(也是由FMC研究出的)一种改进。Form Coke方法中也是使煤在约950°F到1000°F下热解以产生焦油和炭。焦油经过适当处理并与炭再合并。将该混合物加热至约1500°F以产生焦炭产物。该方法可干净地从非焦煤中产生焦炭。一家建在怀俄明州Kemerer的工厂利用该方法每年生产约93,000吨焦炭。Form Coke方法和COED方法的不同之处在于在COED方法中，燃烧炭产物，得到的烟道气提供使煤热解的热量。
其它公司研究出了利用类似的方法产生合成甲烷气体的装置，然而其中用温度升高的方法以减少焦油和油类。较高的温度使焦油热裂解而产生H2、CO和CH4。高炉焦炭生产中煤的热解温度高于煤渣软化温度。所产生的焦油用于获得其化学制品。长链的环烃类(煤焦油)裂解成各种链烷烃、链烯烃以及环状和芳族烃类的混合物。
最近，人们正在研究利用先进的增压流化床燃烧循环技术(PFBC)在较高温下热解煤(现在称之为适度气化(mild gasification))以产生低热量值气体(low Btu gas)和炭的设想。此外，加入石灰石和白云石具有脱硫特性。低热量值气体用于升高由PFBC产生的烟道气的温度以提高循环效率，并燃烧PFBC中的炭。目前，一些公司出于此目的而在研究适度气化法。其他一些公司也开始研究先进的PFBC循环。研究这种新型碳化器或适度气化法的主要推动力在于产生气体和炭不产生焦油或油类。碳化器中加入吸附剂促进在较低的温度下对组成焦油的长链烃的裂解。
这样一来，需要一种能将尽可能多的热引入进入碳化器的气流的装置，以去除挥发物及通过热解减少焦油和油类。人们加入吸附剂帮助焦油裂解从而促进热化学反应。
本发明提供一种两步碳化器解决上述现有技术中及其他的难题。该改进的热化学反应装置包括一个碳化器，它含有一个与燃烧室连接的可流化材料的床。该燃烧室产生的烟道气用作为碳化器的两种流化媒质之一。来自燃烧室的热烟道气从中间管道上升以使在外管道中的碳化器空气预热。来自外管道的空气用作第二种流化媒质。煤和吸附剂通过一个密相传输***由压缩空气送入碳化器进行燃烧。燃烧器中的炭及用过的油石从碳化器中的溢流管除去以作进一步的燃烧。
因此，本发明的一个目的是提供一种改进的用于热化学反应的两步碳化器。
本发明的另一个目的是提供一种改进的使用两步碳化器进行热化学反应方法。
本发明还有一个目的是提供一种装置，其设计简单，结构结实，制造费用低廉。
本发明的各种新颖特点在所附的权利要求书中作了详细描述并成为本发明叙述的一部分。为了更好地理解本发明，及使用本发明所能达到的优点，请参阅下面的附图及叙述性内容，其中，对本发明的一较佳实施例作了说明。
在附图中，图1为本发明装置的正面剖视图。
请参阅图1，本发明装置将尽可能多的热引入进入碳化器(10)的气流，以去除挥发物及通过热解减少焦油和油类。加入一种吸附剂(例如石灰石或白云石)以促使焦油和油类的量减少，帮助焦油裂解，以及吸附燃烧期间形成的以H2S形式存在的任何硫。
来自某一源(未予画出)的煤(12)和吸附剂(14)通过一个密相传输***由压缩空气送入碳化器(10)。密相传输限制了传输固体粒子流所需的空气量。除了图中指出的几处之外，碳化器(10)基本上为一个封闭容器并成为一个流化床，高速流体的射流通过在其底部的格栅板(16)而使该床充分混合。
当煤(12)和吸附剂(14)进入碳化器(10)时，与至少两种流体(最好是气体流)接触。气体流中的一种最好是已预热过的空气(A)，另一种为由燃烧室(18)产生的烟道气(F)。煤(12)在碳化器(10)中被脱去挥发成分并部分燃烧。同时吸附剂(14)吸附任何以H2S形式存在的硫并形成硫化钙(CaS)。碳化器(10)最好在1600F左右运行。来自燃烧过的煤和吸附剂的炭和用过的油石以及其它部分燃烧的物质进入一个溢流管(20)，该溢流管连接碳化器(10)和燃烧室(18)。任何离开碳化器(10)的固体细颗粒用一台热旋风分离器(22)收集，并通过一旋风分离器立管(24)和肘形弯管(25)回到燃烧室(18)的底部。
燃烧室(18)燃烧部分炭和剩余的挥发性物质并使部分CaS转变成CaSO4，后者保持其固体状态(19)。燃烧室的工作温度低于煤灰的渣化温度。炭和用过的油石的残余物以及其它燃烧过的物质通过位于底部的管道(26)离开燃烧室(18)成为废弃物等待处理。
如图1所示，燃烧室(18)最好是由一个同心或同轴空气管道(28)形成的环形中心管道。燃烧室(18)为轴向排列且同轴地位于空气管道(28)内。燃烧室(18)产生热的烟道气，它沿燃烧室(18)管道中部上升并穿过格栅板(16)(如箭头F所示)进入碳化器(10)。同时燃烧室(18)使碳化器空气和/或来自一源(未予画出)的由箭头B所示的方向供给空气管道(28)的水蒸汽预热。燃烧空气和/或水蒸汽由箭头C所示方向从一源(未予画出)供给燃烧室(18)。控制允许进入燃烧室的空气和/或水蒸汽的量以限制碳化器的温度低于2,000°F，从而不需任何内床冷却面(in-bed cooling surface)。进入两步碳化器的空气总量保持煤燃烧的亚化学计量。预热的空气和/或水蒸汽(A)穿过格栅板(16)用作碳化器(10)的第二种流化媒质。
碳化器(10)的流化床运行速度高于碳化器中通常的流化速度，以促进与来自燃烧室(18)的热气体的混合，这样使煤脱去挥发成分并使焦油和油类热裂解(由于煤和热烟道气直接接触)。正如前面提到的，来自碳化器(10)的产物通过管道(21)进入热旋风分离器(22)，在那儿固体物被送回燃烧室(18)的底部。产生的气体通过管道(30)离开热旋风分离器(22)用于进一步的加工、反应或排放。
有利的是空气管道(28)作为对燃烧室(18)的加压密封，这样使该装置能在高压下(约12-20大气压(atm))工作。
两步碳化器的运行具有灵活性，因为进入碳化器和燃烧室的空气是分别可调节的。当增加进入碳化器的空气流量时，煤流量增加，从而提高温度和气化程度。同样地，可注入水蒸汽以促进汽化。
虽然本文显示和详细叙述了本发明的一个具体实例用以说明本发明原理的应用，应该理解的是本发明也完全可以以另外的方式具体实施而不脱离这些原理。
