摘要：
針對石化場所可燃氣體探測系統存在的監測盲區、回應滯後及多源洩漏等監測不足問題，通過優化探測器佈置，提升洩漏風險動態感知能力，降低火災爆炸事故風險。再者，通過梳理催化燃燒、紅外吸收等傳統技術與光纖傳感、鐳射光譜等新型技術的原理特性，對比國內外標準規範差異，建立技術選型準則。此外，通過對石化企業調研與事故案例分析，針對石化場所各類問題，結合應用實例對問題進行優化。最後，以覆蓋效率、回應時間與經濟性為協同優化目標，提出佈置策略。本研究為石化場所可燃氣體探測系統的標準化佈置與優化升級提供了理論依據，對完善安全防控體系、降低事故概率具有重要實踐價值。

Research on Optimization Layout Strategies for Combustible Gas Detectors in Petrochemical Sites
Wang Haoyu; Yan Chuzheng

Abstract：
To address monitoring deficiencies in combustible gas detection systems at petrochemical sites—such as blind spots, delayed responses, and multi-source leakages—this study optimizes detector layout to enhance dynamic perception of leakage risks and reduce the likelihood of fire and explosion accidents. By reviewing the principles and characteristics of traditional technologies (e.g., catalytic combustion and infrared absorption) and emerging technologies (e.g., fiber optic sensing and laser spectroscopy), and comparing differences between domestic and international standards, we establish a technology selection criterion is established. Through field investigations at petrochemical enterprises and accident case analyses, optimization measures are proposed for various site-specific issues, supported by practical application examples. Finally, with coverage efficiency, response time, and cost-effectiveness as co-optimization objectives, an optimization strategy is put forward. This research provides a theoretical basis and actionable strategy for the standardized layout and upgraded design of combustible gas detection systems in petrochemical sites, offering significant practical value for improving safety defense systems and reducing accident probabilities.
