Abstract
The chemical production process involves a large number of flammable and explosive substances, and its safety issues have always been a key focus of the industry. To effectively reduce the risk of explosion and ensure production safety, this study systematically investigates the explosion-proof safety design in chemical production. The research background is based on the frequent occurrence of chemical accidents in recent years, especially the severe threats posed by explosion accidents to human life, property, and the environment. To address these challenges, this study aims to enhance the inherent safety of chemical production systems through optimized explosion-proof design strategies. A combination of theoretical analysis and numerical simulation was employed to thoroughly explore the mechanisms of explosion propagation, the dynamic characteristics of pressure waves, and the effectiveness of protective measures. Furthermore, a multi-level explosion-proof design scheme was constructed based on practical case studies. The results indicate that the implementation of zonal isolation technology, optimization of pressure relief structure parameters, and reinforcement of inert control methods can significantly mitigate the impact effects of explosions and improve the system's resistance to explosions. The main innovation of this study lies in the proposal of an integrated explosion-proof design fr amework, which comprehensively considers the influence of process flows, equipment layout, and environmental factors, thereby enabling more precise risk assessment and prevention. Additionally, a set of numerical simulation tools applicable to complex operating conditions has been developed, providing strong support for engineering practice. Overall, this study offers new ideas and technical support for explosion-proof safety design in the chemical industry, with significant theoretical value and application potential..
