一种实时在线监测的双底结构储油罐研究

Research on a Double Bottom Oil Tank with Real-Time Online Monitoring

通过单底板储油罐罐底的特殊性分析,发现储油罐底板两面腐蚀易穿孔引发渗(泄)漏事故,因罐底腐蚀隐蔽性强,且无有效的实时在线检漏设备和技术,罐底实时在线监测已成为行业研究的重点和难点。针对单底板储油罐固有缺点,在分析储油罐基础检漏层结构设计和复合罐底结构设计不足后,总结出将底板结构设计和渗(泄)漏监测技术有机结合起来破解难题的方法;提出一种配备有油气在线探测仪和真空系统或压力系统的双底结构储油罐设计,能够实现对储油罐底板的实时在线监漏,有效保障储油罐的安全运行。

By analyzing the particularity of the bottom of single-bottom tank,it was found that corrosion on both sides of the oil tank bottom made the bottom perforate easily and cause leakage.Due to strong concealment of corrosion at the tank bottom and the lack of effective real-time online leakage detection equipment and technology,real-time online leakage monitoring on tank bottom has become the focus and difficult point in industry.Aiming at the intrinsic defects of single-bottom storage tanks,the method of combing bottom structural design with leakage monitoring technology organically was put forward after analysis on the shortcomings of structural design on the oil tank foundation leakage detection layer and composite tank bottom.Finally,a double bottom oil tank with online oil & gas detector and vacuum or pressure system was proposed to realize the real-time online leakage monitoring on tank bottom,and effectively guarantee the safe operation of oil tank.
