Background
At present, for an external floating roof oil tank, in order to ensure that a floating disc can flexibly move up and down, a gap with a certain distance is inevitably formed between the floating disc and the tank wall, so that an annular space with exposed oil surface is formed; the oil in the annular space of this exposed oil level will certainly volatilize, consequently for preventing that oil gas from volatilizing, need seal the setting to the annular space between floating plate and the jar wall.
Today, conventional sealing arrangements commonly take the form of a double seal; the primary sealing means is the direct cover of the oil surface. The commonly used primary sealing mainly comprises three forms of filling type elastic soft sealing, liquid filling type soft sealing and mechanical sealing. In order to guarantee better sealing effect, secondary sealing is arranged outside the primary sealing to form protection of the primary sealing and further reduce oil gas loss.
However, in practical application, it is found that due to the reasons that the tank body is settled and deformed, or the primary seal itself is aged and damaged, and the residual oil on the tank wall is continuously volatilized, oil gas accumulation is often generated in the space between the primary seal and the secondary seal of the storage tank, and partial concentration even exceeds the oil gas explosion lower limit, at this moment, ignition sources such as thunder, static electricity and open fire can be met, and the sealing ring explosion accident can be caused. Sealing ring burning explosion accidents caused by lightning strike occur at home and abroad, and the safe operation of an external floating roof oil tank is seriously threatened.
