Problems solved by technology

Since the sealing tape has a T-shaped structure, the sealing tape will be greatly affected by the primary sealing state during the operation of the storage tank. The primary sealing will apply external force to the upper part of the secondary sealing through the sealing tape, which will easily cause the collapse of the secondary sealing. At the same time, the secondary sealing Corresponding protective measures are not taken at the connection between the upper part and the storage tank, which will easily cause a large amount of oil and gas to accumulate in the upper part, bringing safety hazards

Embodiment Construction

[0045] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0046] First of all, it should be noted that in this embodiment, the direction from the storage tank wall 50 to the edge plate 40 of the floating plate is defined as an inward direction, and the direction from the edge plate 40 of the floating plate to the wall 50 of the storage tank is defined as an inward direction. Therefore, the side of the tank wall 50 facing the edge plate 40 of the storage tank is the inner side of the tank wall, and the side of the edge plate 40 facing the tank wall 50 is the outer side of the edge plate of the floating plate. The side of the floating plate edge plate 40 away from the storage tank wall 50 is the inner surface of the floating plate edge plate.

[0047] Such as figure 1 As shown, a high-efficiency oil-free and gas-free sealing device for floating roof storage tanks, the device includes the following com...

Abstract

The invention relates to an efficient and oil-gas-free sealing device for a floating roof storage tank. The efficient and oil-gas-free sealing device comprises a primary sealing assembly, a secondarysealing assembly and an oil-gas-free sealing assembly, wherein the primary sealing assembly and the secondary sealing assembly are arranged between the inner side surface of the tank wall of the storage tank and the outer side surface of a floating disc edge plate, the oil-gas-free sealing assembly comprises a spongy soft elastic object, a floating roof storage tank space between the primary sealing assembly and the secondary sealing assembly is filled with the spongy soft elastic object, the spongy soft elastic object is moved up and down with the floating of the floating disc edge plate, thesealing of the floating roof storage tank space between the primary sealing assembly and the secondary sealing assembly is achieved, and a serrated protrusion of an oil-gas-free sealing section is arranged at the attachment position between a macromolecule oil-gas tooth film and the inner tank wall of the storage tank. According to the efficient and oil-gas-free sealing device, the oil-gas spacebetween the primary sealing and the secondary sealing can be greatly reduced without affecting the safe operation of the primary sealing and the secondary sealing of the storage tank, and the safe operation of the storage tank is ensured.

Description

technical field [0001] The invention relates to the technical field of sealing of floating roof storage tanks, in particular to a high-efficiency oil-gas-free sealing device for floating roof storage tanks. Background technique [0002] At present, the sealing form of large storage tanks at home and abroad is basically a combination of primary and secondary sealing devices. Although this combination has the advantages of wide application, easy maintenance, and long service life, this large-scale seal still cannot be completely sealed. Due to the breathing process of the floating roof, the volatilization of the condensed oil on the tank wall, etc., there will inevitably be oil and gas accumulated in the closed space between the primary and secondary seals, forming an oil and gas space. At present, the combined form of primary and secondary seals has a large volume of confined space. When the concentration of oil and gas reaches the flash point, it will bring a greater safety ...
