摘要
热解作为废旧轮胎处置的重要技术手段,可以有效实现其减量化、无害化和资源化利用。本文综述了废旧轮胎热解的影响因素以及热解产物的研究进展,对废旧轮胎热解的经济、环境和社会效益进行了说明,指出当前工业化热解废旧轮胎存在的问题,并展望了未来节能环保式热解工艺的应用前景。结合现有的工业化热解设备,优化工艺条件和反应器结构型式,进一步分析了热解产物即热解气、热解油及热解炭的成分结构与应用,通过对热解产物改性活化与提质处理,创造更大的经济效益。提出应基于环境法规要求和绿色发展理念,糅合多种处理技术,研制适合废旧轮胎热解的工艺装备,开发集收集/预处理/热解/产物回收与提质于一体的废旧轮胎处置技术,实现废旧轮胎高效清洁转化和高值利用。
Pyrolysis of waste tires,as an important disposal means,could effectively achieve its reduction,harmlessness and resource utilization.This article reviewed the influencing factors of pyrolysis process of waste tires and the progress of pyrolysis products,carried out economics evaluation,and analyzed environmental and societal benefits,pointed out the current problems in industrial pyrolysis process of waste tires,and prospected future application of energy-saving and environmentally friendly pyrolysis process.In combination with the existing industrial pyrolysis equipment,the process conditions and reactor configurations were optimized.Pyrolysis products,i.e.pyrolysis gas,oil and char,were further analyzed for greater values through modification and upgrading techniques.Based on environmental regulations and green development concepts combined various treatment technologies,it was proposed to develop process equipment suitable for pyrolysis of waste tires and waste tires disposal technology that integrated collection/pretreatment/pyrolysis/product recovery and quality improvement to achieve efficient and clean conversion and high value reutilization of waste tires.
