Abstract

The invention discloses a combined type floating roof tank sealing device. The device comprises a floating roof main body, wherein a nitrogen bag is arranged on the lower end face of the floating roofmain body, and the floating roof main body is of a cake-shaped structure; a primary sealing mechanism is arranged on the side face of the floating roof main body, the primary sealing mechanism comprises multiple layers of clamping plates, annular air bags are arranged between the adjacent clamping plates in a sleeving mode, and the annular air bags communicate with the nitrogen bag through a partial pressure pipeline mechanism; a plurality of circumferentially arranged protrusions are arranged on the outer side wall of the annular air bags, the outer edges of the protrusions are arranged beyond the outer edges of the clamping plates, and after gas in the nitrogen bag is pressed into the annular air bags, the protrusions tightly press the inner wall of a floating roof tank, so that the floating roof tank below the floating roof main body forms a closed space; and a mounting plate used for mounting a secondary sealing mechanism is arranged at the edge of the upper portion of the floating roof main body. The device has the advantages of being simple in structure, good in sealing performance, long in service life, not prone to generate the situation that a floating roof is clamped andthe like.

Description

technical field [0001] The invention belongs to the technical field of floating roof tanks, and in particular relates to a sealing device for combined floating roof tanks. Background technique [0002] The floating roof of the storage tank is a floating roof that floats on the surface of the liquid storage. It floats up and down with the input and output of the storage liquid. There is an annular space between the floating roof and the tank wall. This annular space has a sealing device, so that The liquid in the tank is isolated from the atmosphere when the top cover floats up and down, thus greatly reducing the volatilization loss of the storage liquid during storage. [0003] Currently used floating roof tanks form an annular space between the tank wall and the floating roof. In order to avoid biogas loss, a seal is made between the floating roof and the tank wall. This seal is between the floating roof and the inner wall of the floating roof tank. An annular rubber elast...
