Description
技术领域
本发明涉及固废资源化的技术领域，具体涉及一种基于高炉渣余热利用的废旧轮胎流化气化的装置和方法。
背景技术
废旧轮胎具有很强的抗热、抗机械和抗降解性，难以自然消解，如果丢弃在自然环境中，不仅占用土地，浪费资源，还会形成一种新的“黑色污染”。因此，实现废旧轮胎环保、高效利用已成为世界难题。再生胶产业是我国废旧轮胎利用最重要的方式，该产业的发展有效地弥补了我国橡胶资源的严重不足。然而再生胶产业在发展过程中存在两大致命弱点—二次污染和易燃易爆。虽然解决了废旧轮胎的“黑色污染”等问题，但是生产过程中又产生了废气、废水污染,被我国列为二次污染行业。
热裂解处理废旧轮胎可以回收燃料气、燃料油、炭黑和钢丝等再生资源,这些再生资源是宝贵的燃料或化工原材料。废旧轮胎热裂解处理量大、适用范围广、产物品种多、废物减容量大，而且热解过程所需能量可以自给。它不仅具有明显的环境效益，而且经济效益也十分可观。然而现有的轮胎裂解技术存在以下问题：
(1)轮胎裂解装置多采用回转窑装置，热质传递效率相对较低，同等处理能力下占地面积大，处理效率低；
(2)轮胎裂解多采用其自身的裂解产物—燃气进行外加热，依靠反应器壁面热传导和热辐射的方式进行，热传递效率低，轮胎热解升温速率低，也导致了热解油产品品质和质量较差；
(3)废旧轮胎裂解产物中油的产品附加值最高，但现有的轮胎裂解工艺其油产率一般在40%～45%左右，经济效益偏低；
(4)轮胎裂解过程中产生的燃气大部分用于轮胎裂解加热，导致裂解工艺能源回收率低。
发明内容
针对现有技术的不足，本发明提供了一种基于高炉渣余热利用的废旧轮胎流化气化的装置和方法，先将液态高炉渣粒化成高温炉渣颗粒，并在表面负载催化剂后，在流化床气化反应器内与轮胎胶粉进行流化换热，胶粉在炉渣热载体和催化剂的作用下发生气化反应，实现油气联产。本发明既实现了废旧轮胎的资源化、减量化和无害化处理，又实现了高炉渣余热的高效回收、利用和转化，为实现上述发明目的，本发明采用下述技术方案予以实现：
本发明提供一种基于高炉渣余热利用的废旧轮胎流化气化的装置，其特征在于，该装置包括炉渣粒化器与流化床气化反应器；所述炉渣粒化器顶部设有液态高炉渣进口，内部设有粒化盘，粒化盘上部设有催化剂粉末喷洒装置与水喷淋装置，底部设有粒化炉渣出口；所述流化床气化反应器顶部设有粒化炉渣进口和气化燃气出口，底部设有布风板和固体残留物出口，布风板表面装有胶粉喷吹管；所述流化床气化反应器的粒化炉渣进口与粒化器的粒化炉渣出口通过星形给料器相连；所述流化床布风板与空气压缩机和胶粉给料器相连。
本发明还提供了一种基于高炉渣余热利用的废旧轮胎流化气化的方法，其特征在于它包括以下步骤：
(1)由高炉排出的液态高炉渣经渣沟分成多股直径为10mm的渣流，进入粒化器进行粒化，粒化过程中同时向处于液固过渡态的粒化渣表面喷水和催化剂粉末，使得炉渣颗粒表面形成多孔且负载催化剂的高温炉渣颗粒，粒化后的颗粒进入流化装置；
(2)当被催化剂包裹的所述炉渣颗粒进入流化床气化反应器内，同时开启空气压缩机和胶粉给料器，由底部布风板通过胶粉喷吹管沿15～45°角向炉渣颗粒表面喷吹轮胎胶粉颗粒，胶粉颗粒与炉渣颗粒发生直接碰撞，在热辐射、对流和接触导热等传热方式下受热分解，生成炭黑和含油燃气；
(3)当炉渣颗粒在流化床气化反应器内经过3~5分钟的停留时间后，同时关闭空气压缩机和胶粉给料器，换热完成后的炉渣颗粒沿着布风板表面由固体残留物出口排出。
国内外现有的轮胎裂解方法中，轮胎裂解需要消耗自身产生的高品质燃气作为热源，能源回收效率低，且多采用外加热方式，通过反应器内壁和物料间接接触传热，热效率低。与现有技术相比，本发明的优点和积极效果是：(1)采用高炉渣余热作为轮胎裂解加热源，以废治废，增加了轮胎裂解技术的适用性，提高了能源利用转化效率；(2)高炉渣中含有多种金属矿物，除了可作为轮胎气化的热载体外，还可以与表面负载的催化剂共同作用，降解转化热解油；(3)采用炉渣热载体与轮胎胶粉流化换热的方式，可明显提高热质传递效率，增加轮胎裂解的升温速率，提高热解油产品品质和质量；(4)采用喷吹催化剂的方法，使得炉渣表面高效负载催化剂，一方面，可以促进催化反应的传质效率，另一方面，还可以降低高温炉渣颗粒的粘性，有效避免颗粒间的相互粘结。
