Description

一种废旧轮胎热裂解系统
技术领域
本发明属于废旧橡胶热裂解工艺技术领域，具体涉及一种废旧轮胎热裂解系统。
背景技术
随着汽车工业的飞速发展，我国废旧轮胎储存量越来越多，数量巨大的废轮胎对环境造成的压力越来越大。废旧轮胎由于其具有很强的抗热性、抗机械性，很难降解，直接堆放不仅占地，还容易发生火灾。如何将废旧轮胎资源化、减量化、无害化，防止环境污染不仅是一个世界难题，同时随着轮胎工业原料石油、天然橡胶资源的缺乏，废旧轮胎的回收、利用还关系到全球持续发展的战略问题，也是我国再生资源利用的新课题。
目前，废旧轮胎的处理技术方向主要有制备胶粉，热解炼油，直接焚烧等。目前，废旧轮胎制备胶粉的方法有常温粉碎方法或低温废旧轮胎改性后的粉碎方法，常温粉碎法是指在常温下利用机械剪切力对轮胎胶片进行切割挤压，将废旧胶粉碎成胶粉的一种方法。
废旧轮胎的热解处理是解决废旧轮胎固体对环境危害的最彻底最有效处理方法，其原理是在隔绝氧气的前提下，高温加热使废旧轮胎中的橡胶聚合物发生裂解反应转化为高温油气、炭黑和钢丝，但现有技术对于热裂解过程中产生的不凝气态物，未进行有效利用和无害化处理，直接排放后将严重污染环境。
发明内容
本发明的目的在于提供一种废旧轮胎热裂解系统，以解决上述背景技术中所提出的问题。
为实现上述目的，本发明提供以下技术方案：一种废旧轮胎热裂解系统，其结构要点在于：包括高温预热罐、螺旋挤出机构、热裂解罐、精磨机、旋风分离器、冷凝收集器、压缩机、轮胎油储罐、热交换器、喷淋塔和UV光氧催化器，去除胎圈钢丝的废旧轮胎通过高温预热罐的进口进入高温预热罐，预热后产生粘流态的橡胶输送至螺旋挤出机构，螺旋挤出机构将粘流态的橡胶通过热裂解罐的进料口挤入热裂解罐并进行裂解，橡胶裂解后产生的炭黑从热裂解罐的固体物料出口出来后输送至精磨机精磨，所述的精磨机的出口与炭黑收集装置相连；所述的热裂解罐的裂解气出口与旋风分离器的进风口相连，所述的旋风分离器的出风口与冷凝收集器的气体进口相连，所述的冷凝收集器的气体出口与压缩机相连，所述的压缩机的出口分别与高温预热罐的燃烧室以及热裂解罐的燃料气进口相连，所的述冷凝收集器的液体出口与轮胎油储罐相连；所述的热裂解罐的燃烧废气出口出来的燃烧废气进过过滤装置过滤后进入热交换器与水换热，所述的热交换器的气体出口与喷淋塔的下部气体进口相连，所述的喷淋塔的中部横向设置有填料，喷淋塔的上部设置有喷淋器，塔体的顶部设有与UV光氧催化器的进口相连的废气出口，且从UV光氧催化器出口出来的气体达标排放。
作为优选的，过滤装置包括至少两层滤网。
作为优选的，填料为沸石或分子筛或活性炭。
与现有技术相比，本发明实现了废旧轮胎整胎连续式的热裂解，无需将废旧轮胎破碎成块状，简化了工艺流程降低了生产成本，同时对裂解过程中产生的不凝气态物进行净化处理，不产生二次污染，达到资源再利用的目标。
