Abstract

Abstract: The research on energy saving and high efficiency organic waste gas treatment technology is of great significance to environmental protection. The common treatment technologies of organic waste gas were introduced briefly in this paper,with emphatical discussion on the regenerative thermal oxidation technology(RTO)and regenerative catalytic oxidation(RCO)technology. The key technologies of regenerative thermal oxidation system design were analyzed,including the heat transfer coefficient and flow resistance of regenerator,the classification of catalysts and their respective advantages and disadvantages,the method of preparation of catalyst,design and selection of reversing system,the start-up technology and so on. Regenerative thermal oxidation technology and regenerative catalytic oxidation technology have been applied successfully at home and abroad. As a result of the instability resulted in the complexity of organic waste components and the intermittent operation of RTO system,how to adapt to the fluctuation of the inlet concentration is a problem that needs to be further studied.

摘要： 研究开发节能、高效的有机废气处理技术对环境保护有重要意义。本文简要介绍了有机废气常见的处理技术，重点论述了蓄热式热氧化技术（RTO）和蓄热式催化氧化技术（RCO）用于处理工业有机废气的工作原理、适用条件。详细分析了关于蓄热式热氧化系统设计的关键技术问题，包括蓄热体的传热与流动阻力、催化剂的分类及各自的优缺点、催化剂的制备方法、换向系统的设计与选用、启动技术。蓄热式热氧化技术和蓄热式催化氧化技术在国内外都已有很多成功的实际运用案例，将来也将有更广阔的应用前景。由于企业有机废气的成分比较多元化、不稳定及企业间歇生产的特点，使得有机废气浓度和废气量都有间歇性变化，导致RTO系统运行不稳定，因此如何适应入口浓度的波动是需要进一步研究的问题。
