Description
Technical field
The present invention relates to a kind of, and the floating roof tank with fire-extinguishing function concurrently seals ring seal device.
Background technique
Floating roof crude oil storage tank once sealing form mainly has mechanical seal, tubular sealed, elastomer seal.But no
There is oil and gas leakage gap at the once sealing of pipe mechanical seal or soft seal；Oil slick volatile matter is hung by tank skin simultaneously
It influences, oil gas can be gathered between first and second sealing.Therefore, the either storage tank of mechanical sealing or soft seal, exists
The risk of fire explosion.
China oil product storage tank overwhelming majority uses fixed low expansion foam extinguishing system, and there are foam consumptions greatly, goes out
The problem of fiery low efficiency, needs by several steps such as fire pump, foam pump, proportioner, fire_fighting pipe network, foam maker
Suddenly foam could be applied on kindling liquid level, and the fire pump room of most of tank fields is far from scene of fire, the starting of system
Journey generally requires 5~10min, has delayed the fire extinguishing best opportunity；The system maintenance simultaneously is at high cost, wants to the technical ability of operator
Ask very high, general staff tends not to be accurately finished these operations.When storage tank occurs explosion or collapses, the fire-fighting
System will lose fire extinguishing effect.
For the risk for reducing petroleum storage tank fire explosion, its fireproof and explosion suppression ability is promoted, CN204110651U proposes one
Kind can guarantee the oil tank active suppression type once sealing device that actively starting is put out a fire in unexpected on fire or abnormal high temperature, primary
Sealing device top is provided with firing-fighting medium generator, can start in the case of fire, realizes fire extinguishing, changes in the prior art
The mode alarmed after fire occurs with fireman's fire extinguishing, while also changing to use in the prior art and be filled for a long time into annular region
Fill out the mode of inert gas.But there is the decline of promotion gas pressure, extinguishing chemical failure etc. and ask in the fire extinguisher of this patent setting
Topic, needs running check or replacement, increases maintenance cost.
CN104370002A has invented a kind of sealing knot of the closed no oil-gas space of lasting disjunctor of floating roof tank floating plate
Structure is further added by sealant tape and vaporization prevention diaphragm on floating roof periphery and constitutes upper ring on the basis of the once sealing of elastic material
The secondary seal for filling secondary seal light filler in shape cavity and being formed.The patent can not only play sealing function, Er Qie
The downward pulling force of rubber flap is not will increase in floating plate uphill process, and the bearing plate for the secondary seal being connected with scraper plate still can
Certain pressing force is generated to tank skin.Oil storage tank overall sealing performance is not only improved, but also reduces the oil between first and second sealing
Gas aggregation, eliminates fire hazard, and cost is relatively low.
CN201980610U proposes a kind of seal ring ventilation explosion suppression device of floating top oil tank, including communicates with floating top oil tank
The air feed branch pipe of external gas transmission main pipe, central distributor, several radial bronchuses, several arc gas distribution pipes.Although the whole series system
The of simple structure and low cost, working service of uniting is convenient, but the patent does not consider the deformation of floating roof tank in active service, irregular
Etc. influence factors, entire sealing ring be not sealing space, ventilative everywhere to leak, the inert gas being charged into leaks quickly
To the greatest extent, maintenance cost is very high；Also, reservoir area further increases maintenance cost there is no inert gas source.
Summary of the invention
The technical problem to be solved by the present invention is to the problems that extinguishing effect in the prior art is poor, provide a kind of new tool
There is the floating roof tank sealing ring seal device of fire-extinguishing function concurrently.The device has the advantages that extinguishing effect is preferable.
To solve the above problems, The technical solution adopted by the invention is as follows: a kind of floating roof tank sealing with fire-extinguishing function concurrently
Ring seal device, including the annular seal being set between tank skin and floating plate, once sealing device therein is that elasticity is close
Envelope, the elastic packing and fixed plate integral outer package rubber seal band and the once sealing device for forming an entirety,
It is filled in the region between floating plate and oil tank, and is fixed on floating plate, under-filled at least two elastic packings in sealing area
The lightweight fire-extinguishing particulate sealed with nonfireproof packaging bag is filled on material, top.
In above-mentioned technical proposal, it is preferable that lightweight fire-extinguishing particulate is inner hollow or the nothing with honeycomb microporous structure
Machine material has carried out hydrophobic oleophobic surface modification treatment by method physically or chemically, when a fire, the not fire resisting
Packaging bag burnt by flame broken, light granules above are hung down, and are swum on pasta, oil gas volatilization are prevented, to cut
Broken flame combustion.
In above-mentioned technical proposal, it is highly preferred that inorganic material be expanded perlite, expanded vermiculite, hollow glass microbead or
Floating bead.
In above-mentioned technical proposal, it is preferable that sealing band and the floating plate place of being connected and fixed are provided with fixation clip, fixation clip
The outside bending in lower end forms bracket, sealing band is held, the bracket and lightweight fire-extinguishing particulate hermetic bag are all set in one
Secondary sealing device top.
In above-mentioned technical proposal, it is highly preferred that apparent density≤0.75g/cm of inorganic material3。
The present invention also provides a kind of floating roof tanks to seal ring seal device, can quickly go out when fire occurs for sealing ring
Fire.Fill fire-extinguishing particulate, nonfireproof sealant tape be placed between once sealing and secondary seal, by sealing band with
The sealant tape of once sealing is fixed on the upside of floating warehouse.When a fire, nonfireproof sealant tape is burnt broken by flame, is filled
Lightweight fire-extinguishing particulate hang down, swim on the pasta of sealing ring, prevent oil gas volatilization, cutting flame burning prevents
Fire spreading achieves preferable technical effect.
