摘要

制药工业生产过程中产生的有机废气排放对环境构成显著压力，RTO（蓄热式热力氧化炉）作为废气治理的核心设备，其蓄热体材料的合理选型与寿命预测对运行效率和经济性至关重要。本文围绕制药行业RTO焚烧炉的应用背景，系统分析不同蓄热体材料的热工性能、耐腐蚀性与机械稳定性，并结合实际运行数据建立寿命预测模型，旨在为企业提供科学的材料选择依据。材料选型不仅决定能耗与处理效率，还直接关系到长期稳定运行与维护成本。通过对材料失效机理的探讨与寿命评估方法的优化，提出提升制药工业RTO焚烧炉运行可靠性与延长寿命的对策，对推动行业绿色发展具有现实意义。

Abstract

The emission of organic waste gas generated during the production process of the pharmaceutical industry poses significant pressure on the environment. As the core equipment for waste gas treatment, the Regenerative Thermal Oxidizer (RTO) relies heavily on the rational material selection and accurate life prediction of its regenerators, which are crucial to the operating efficiency and economic viability of the equipment. Focusing on the application background of RTO incinerators in the pharmaceutical industry, this paper systematically analyzes the thermal performance, corrosion resistance, and mechanical stability of different regenerator materials. Furthermore, a life prediction model is established based on actual operation data, aiming to provide enterprises with a scientific basis for material selection. Material selection not only determines energy consumption and treatment efficiency but also directly affects long-term stable operation and maintenance costs. By discussing the failure mechanism of materials and optimizing life assessment methods, countermeasures to improve the operational reliability and extend the service life of RTO incinerators in the pharmaceutical industry are proposed. This study holds practical significance for promoting the green development of the industry.
