Abstract

The invention discloses a sealing device for secondary sealing of an outer floating roof storage tank and an outer floating roof storage tank. The sealing device for secondary sealing of an outer floating roof storage tank includes a sealing plate (1) and a pressing device (2), The pressing device (2) comprises an arc-shaped steel plate (3), a pressing plate (4), a spring (5) and a support plate (6), the pressing plate (4) and the sealing plate (1) are stacked, and the spring ( The two ends of 5) are respectively connected with the arc-shaped steel plate (3) and the support plate (6), the spring (5) is in an elongated state, and the spring (5) can make the pressing plate (4) through the arc-shaped steel plate (3). ) to press the sealing plate (1). The sealing device for the secondary sealing of the outer floating roof storage tank can equipotentially connect the floating plate of the outer floating roof storage tank with the tank wall, and can keep it tightly attached to the tank wall during long-term operation, ensuring that the outer floating roof storage tank safe operation.

Description

technical field [0001] The invention relates to the field of oil storage equipment, in particular to a sealing device for secondary sealing of an external floating roof storage tank, and also to an external floating roof storage tank. Background technique [0002] At present, my country's external floating roof storage tanks generally adopt a combination of primary and secondary sealing. Due to the uneven settlement of the storage tank, the surface wear of the sealing rubber, etc., there is a gap between the primary seal and the tank wall, and oil and gas leak into the space between the primary seal and the secondary seal. In addition, when the floating plate slowly descends, the oil product will adhere to the tank wall. Since the external temperature is usually lower than the oil temperature, the oil product will form an oil film, and the oil and gas on the surface of the oil film will volatilize between the primary and secondary sealing devices. A gas-oil mixture is forme...
