摘要

摘要: 基于自主设计的废轮胎梯级螺旋热解中试装置,提出了一种与燃煤机组耦合的废轮胎资源化利用新工艺,并通过中试装置连续运行实验,分析了装置运行的稳定性和产物特性,验证了与燃煤机组耦合生产的可靠性。所开发的热解系统采用梯级热解和热解油循环喷淋冷凝技术,实现了热解炭黑、热解油和热解不凝气产率的稳定控制,在实现热解炭黑甲苯透光率达到99%的同时,获得不同闪点组分的热解油产物。废轮胎热解产生的不凝气可维持装置热自持运行,显著降低热解过程能量输入要求。废轮胎热解产生的低闪点油和富余不凝气作为燃煤机组的耦合替代燃料,实现轮胎热解过程污染物超低排放的要求,同时降低了碳排放。研究结果证明了燃煤机组耦合的废轮胎梯级热解连续高效稳定运行的可行性和可靠性,有助于实现废轮胎热解装置规模化生产的推广应用。

Abstract: Based on the self-designed hollow auger series pyrolyzer (HASP) for waste tires in pilot scale, continuous operation experiments were carried out to analyze the stability and characteristics of products, as well as the reliability of production coupling with coal-fired units. Series pyrolysis technology and circulating spray condensation technology of pyrolysis oil were adopted to achieve stable control of pyrolysis carbon black, pyrolysis oil, and pyrolysis non-condensing gas yield in pilot pyrolysis plants. It can obtain high quality carbon black with toluene transmittance at 99%, and achieve effective separation of oils in different flash points. The non-condensing gas generated from the pyrolysis of waste tires can maintain the thermal self-sustaining operation of the plant and significantly reduce the energy input requirement during the pyrolysis process. The low flash point oil and surplus non-condensing gas were used as coupling alternative fuels for coal-fired units to reduce coal consumption and the low pollutant and carbon emissions. The experimental results proved the feasibility and reliability of the continuous, efficient, and stable operation of HASP coupled with coal-fired units, which was conducive to the popularization and application of large-scale production of waste tire pyrolysis installations.
