摘　　要：近年来,管沟内油气管道运营的风险日益凸显,国内外已经发生多起地下管沟内油气泄漏聚集不易发现造成爆炸事故,确保管沟内油气管道安全运行是重中之重。但由于管沟内环境恶劣,特别是海边码头管沟内环境更为恶劣,台风期间管沟内积水严重,使得传统的可燃气体和有毒气体检测设备难以稳定运行,加大了管沟安全管理的难度。为解决这一问题,提出了一种泵吸式双气体检测系统,并在码头管沟中成功应用。该系统采用先进技术和创新设计,能够有效吸入管沟内的气体样本,并进行快速、准确地分析和检测。在恶劣环境中稳定运行的能力和对可燃气体及有毒气体泄漏的及时发现,显著提高了码头管沟的安全性。通过这一技术创新,能有效预防潜在的爆炸事故,保护工人和周围环境的安全。该装置的成功应用将为油气管道行业安全管理提供有力支撑,确保管沟的安全性。In recent years,the increasing risks associated with the operation of oil and gas pipelines within trenches have become more prominent.Numerous incidents,both domestically and internationally,have involved undetected accumulation of oil and gas leaks within underground trenches,resulting in explosion accidents.Ensuring the safe operation of oil and gas pipelines within trenches is of paramount importance.However,the general environment within these trenches is harsh,particularly in coastal harbor trenches.During typhoons,severe water logging within the trenches makes it challenging for traditional flammable and toxic gas detection equipment to operate reliably,thus increasing the difficulty of trench safety management.To address this issue,a pump-suction dual-gas detection system is developed,which has been successfully implemented in harbor trenches.This system utilizes advanced technology and innovative design to effectively draw gas samples from within the trenches and conduct rapid and accurate analysis and detection.Its ability to operate stably in harsh environments and promptly detect leaks of flammable gases and toxic gases significantly enhances the safety and reliability of harbor trenches.This technological innovation can effectively prevent potential explosion accidents and safeguard the safety of workers and the surrounding environment.The application of this system will provide robust support for safety management in the oil and gas pipeline industry,ensuring the safety and reliability of trenches.
