Temperature Field Simulation of a Reaction Furnace Using ABAQUS

摘要: 在高温化学反应过程中，反应炉内部温度的精确控制是决定产物质量与工艺效率的关键因素。传统反应炉设计在多区温度控制方面存在均匀性不足、响应滞后等问题，亟需通过仿真手段进行优化。本文针对某型反应炉，基于ABAQUS有限元平台开展稳态温度场仿真分析，重点研究其在多工况下的温度分布特性与PID控制策略的有效性。仿真结果表明，该反应炉能够将各工作区温度稳定控制在设定区间内，但部分区域由于存在加热器间的热耦合，出现过热和温度不足的问题，控制策略和结构设计需要进一步的改进。本文通过对某型反应炉进行仿真，并根据仿真结果提出改进意见，旨在为同类反应炉的热设计与控制优化提供理论依据。

Abstract: In high-temperature chemical reaction processes, precise control of the internal temperature within the reactor is a critical factor determining product quality and process efficiency. Traditional reactor designs suffer from issues such as insufficient uniformity and response lag in multi-zone temperature control, necessitating optimization through simulation. This paper focuses on a specific reactor model, conducting steady-state temperature field simulation analysis using the ABAQUS finite element platform. The study emphasizes investigating its temperature distribution characteristics under multiple operating conditions and the effectiveness of PID control strategies. Simulation results indicate that the modified structure can stably maintain temperatures within the set range across all working zones. However, thermal coupling between heaters in certain areas leads to overheating and insufficient temperature issues, necessitating further refinement of both control strategies and structural design. By simulating this specific reactor model and proposing improvements based on simulation outcomes, this study aims to provide a theoretical basis for thermal design and control optimization in similar reactors.
