Problems solved by technology

[0004] There are two main technical means at home and abroad to eliminate the oil and gas accumulation space of the sealing ring. One is the purge replacement method, which uses online analysis and gas replacement, which can Comprehensive elimination of oil and gas space, but overall larger nitrogen consumption
The second is the packing method, which reduces the oil and gas space by filling rubber bags in the primary and secondary sealed spaces, but the packing method cannot completely eliminate the oil and gas space, and will lead to new safety hazards after the rubber bag is damaged

Abstract

The invention belongs to the technical field of petrochemical engineering, and particularly relates to an oil-gas-free sealing protection system and protection method for an external floating roof oil tank. According to the technical scheme, the oil-gas-free sealing protection system for the external floating roof oil tank involves a sealing bag arranged in a secondary sealing structure, wherein the sealing bag is located in a space defined by a primary sealing structure, a tank wall, the secondary sealing structure and a floating disc, the sealing bag is connected with an analysis control device through a pipeline, and the analysis control device is connected with an inert gas supply device through a pipeline and is also electrically connected with a control system. The invention provides the oil-gas-free sealing protection system and protection method for the external floating roof oil tank.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to an oil-gas-free sealing protection system and a protection method for an external floating roof oil tank. Background technique [0002] The outer floating roof oil tank has the advantages of low oil loss and environmental protection. However, oil and gas are easy to accumulate in the sealing ring of the outer floating roof oil tank. If the oil and gas concentration reaches the explosion limit concentration range and there is enough ignition energy, it will easily The explosion caused an accident and caused great impact. Therefore, there is a potential safety hazard of oil and gas accumulation in the primary and secondary sealing spaces of the outer floating roof oil tank, which seriously threatens the safe operation of oil depots and petrochemical industries. [0003] At home and abroad, the manual detection method is mainly used to detect the combusti...
