摘　　要：针对拱顶罐传统清洗工艺能耗高、风险系数高、清洗周期长、人工劳动强度大、环境污染重等弊端,研发了拱顶储罐可视化机械清洗技术。其工艺原理:利用设备的抽吸过滤、加压加热循环、可视化喷射等对罐内非流动性油品进行溶解回收,最后通过热水将罐内表面清洗干净,使罐内可达动火检修的要求。现场实践应用证明:与原有清洗工艺相比,该工艺清洗工期缩短为原来的60%,罐内油品回收量增加了98%;同时,该工艺在安全风险、人工劳动强度、环境污染程度及施工成本等方面都有大幅降低。The traditional cleaning technique of dome roof tank has the shortages of high energy consumption and risk factor,long cleaning cycle,high labor intensity and heavy environmental pollution.So,a visualized mechanical cleaning technique for dome roof tank is developed.By suction filtration,pressurized and heating cycles and visualization of the equipment,the technique can dissolve and recycle the non-flowing oil products in tank.After hot water is used to clean the inner surface of tank,the requirements of open fire maintenance are met.Field application proves that compared with the original cleaning technique,the new technique can reduce the cleaning period by 60% and increase the recovery of the oil products by 98%.Besides,the new technique can reduce safety risk,labor intensity,environmental pollution and construction cost greatly.
