Description

生物质不可凝气利用系统
技术领域
本发明属于生态油制备技术领域，具体是涉及一种生态油制备过程中产生的不可凝气的利用系统。
背景技术
生态油制备工艺的主要过程是：生物质原料在气化反应器中反应产生裂解气，裂解气经过分离器的气固分离步骤将气体中含有的炭和热载体分离出来，干净的裂解气经过冷凝塔的冷却步骤形成生态油，冷凝后的不可凝气需将其直接放散燃烧完毕或是循环利用供给烘干炉燃烧产生热能以烘干生物质原料。上述不可凝气的前种处置方法浪费了燃气，不可采纳，后种处置方法虽然实现循环利用，体现了资源循环利用理念，但相对烘干炉的供需量来说，利用量微少，可忽略不计。因而，如何有效利用不可凝气，既不会浪费燃气又可体现循环利用的潜在价值，需要提出新的技术见解。
发明内容
为了解决现有技术存在的问题，本发明提供一种有效循环利用不可凝气的系统。
为了实现以上目的，本发明采取的技术方案是：一种生物质不可凝气利用系统，包括烘干生物质原料的烘干炉、产生裂解气的循环流化床反应器、分离裂解气和固体物的气固分离器、冷凝裂解气成生态油的双级喷淋塔，及燃烧固体物的副反应器，双级喷淋塔的出气口分别与循环流化床反应器的进风口和烘干炉的炉膛之间连接管路。
与现有技术相比，本发明的优点是：通过将不可凝气循环回收输入给循环流化床反应器参与生物质裂解反应，不仅有效回收不可凝气而不浪费，且由于不可凝气不含氧气而使气化反应过程保持惰性气体环境，增加系统的安全性，而多余的不可凝气则给烘干炉燃烧利用，实现不可凝气循环利用最大化。
附图说明
图1为生物质不可凝气利用系统的结构示意图。
具体实施方式
如图1所示，生物质不可凝气利用系统包括烘干炉、循环流化床反应器、副反应器、气固分离器、双级喷淋塔。
循环流化床反应器裂解反应产生的气体通过管路输入气固分离器，气固分离器的气体通过管路输入双级喷淋塔，双级喷淋塔的气体通过管路输入循环流化床反应器或烘干炉的炉膛。
气固分离器的固体通过管路输入副反应器，副反应器燃烧产生的烟气通过管路输入循环流化床反应器，以补充热能。
生物质不可凝气利用系统的工作原理是：热载体(砂)存在于循环流化床中反应器中作为加热生物质原料的介质。烘干炉将生物质湿原料烘干后输入循环流化床反应器，经过裂解反应后产生裂解气，含有炭和热载体的裂解气输入气固分离器，分离出来的干净裂解气输入双级喷淋塔，裂解气中的可凝气被冷凝成为生态油，不可凝气则循环回收输入给循环流化床反应器，作为循环流化床反应器的鼓风。由于不可凝气中不含氧气，循环流化床反应器产生的裂解气不会因富氧环境而产生燃烧，不可凝气的有效利用不仅避免了浪费，同时，通过参与生物质裂解反应，使循环流化床反应器的气化反应过程保持惰性气体环境，增加系统的安全性。当循环流化床反应器所需的不可凝气量满足要求时，多余的不可凝气输入给烘干炉的炉膛中燃烧，使不可凝气得以最大化利用。
