Embodiment 1

[0019] A floating roof tank sealing ring sealing device with fire extinguishing function, such as figure 1 As shown, it includes an annular sealing device arranged between the tank wall and the floating plate, wherein the primary sealing device is an elastic seal, and the elastic seal and the fixing plate are integrally wrapped with a rubber sealing tape to form an integral primary sealing device. It is filled in the area between the floating plate and the oil tank and fixed on the floating plate. The lower part of the sealed area is filled with at least two elastic sealing materials, and the upper part is filled with light fire extinguishing particles sealed in non-refractory packaging bags. The light fire extinguishing particles are expanded perlite.

[0020] When a fire breaks out, the non-refractory packaging bag is burned by the flame, and the light particles on it are scattered and float on the oil surface, preventing the volatilization of oil and gas, thereby cutting of...

Embodiment 2

[0022] A floating roof tank sealing ring sealing device with fire extinguishing function, such as figure 2 As shown, without changing the structure of the primary seal, the light fire extinguishing particles are contained in the sealed bag on the upper part of the primary soft seal, and the upper part of the sealed bag is fixed at the joint of the floating plate with the fixed pressure plate of the primary seal rubber strap. The lower end of the sealed bag falls on the primary sealed rubber strap; or the lower end of the fixed pressure plate is bent outwards and upwards to form an L-shaped bracket to support the sealed bag. The light fire extinguishing particles are hollow glass microspheres.

[0023] When a fire breaks out, the non-refractory packaging bag is burned by the flame, and the light particles on it are scattered and float on the oil surface, preventing the volatilization of oil and gas, thereby cutting off the flame combustion.

Abstract

The invention relates to a floating top tank sealing ring sealing device with a fire extinguishing function, and aims at mainly solving the problems of too much time consumption for enabling fire extinguishing equipment and poor fire extinguishing effects in the prior art. The floating top tank sealing ring sealing device with the fire extinguishing function, which comprises an annular sealing device body arranged between the wall of a floating top tank and a floating disc, is adopted, wherein the one-time sealing device body belongs to elastic seals, and is formed by wrapping the bodies of the elastic sealing and a fixing plate by a rubber sealing belt in an integrated mode and used for filling an area between the floating disc and an oil tank and fixed to the floating disc; the lower portion of the interior of the sealing area is internally filled with at least two elastic sealing materials, and the upper portion is filled with light fire extinguishing granules sealed by a packagingbag not endurable to fire. According to the technical scheme, the problems above are well solved, and the sealing device can be used for sealing of floating top tank sealing rings.

Description

technical field [0001] The invention relates to a sealing device for a sealing ring of a floating roof tank with a fire extinguishing function. Background technique [0002] The primary sealing forms of floating roof crude oil storage tanks mainly include mechanical seals, tubular seals, and elastic material seals. However, regardless of the mechanical seal or the soft seal, there is an oil and gas leakage gap at the primary seal; at the same time, due to the influence of volatile oil floating on the tank wall, oil and gas will accumulate between the primary and secondary seals. Therefore, whether it is a mechanically sealed or soft-sealed storage tank, there is a risk of fire and explosion. [0003] The vast majority of oil storage tanks in my country use fixed low-multiple foam fire extinguishing systems, which have the problems of large foam consumption and low fire extinguishing efficiency. Only one step can be used to apply the foam to the fire liquid surface, and the ...
