Description
Technical field
The utility model relates to sealing device, in particular to a kind of spring-piece type high-efficiency sealing device.
Background technique
Floating top oil tank swims in floating roof on liquid level due to being provided with, and oil gas volatilization loss is made to be reduced to a minimum, because
And it is widely used.But due to the needs of manufacture floating roof and floating roof operation, there is an annular space between tank skin and floating roof, become
Floating roof tank oil and gas loss, pollution and the main cause for causing fire.
Now with the large size of domestic refinery and oil depot scale, the requirement to the sealing of oil storage tank floating plate is higher and higher.In recent years
Carry out the frequent generation of storage tank floating plate sealing ring lightning stroke fire accident, reason is mostly floating plate sealing leak.To guarantee the tight of storage tank
The flexibility of close property and floating roof, needs to be arranged floating roof sealing system.The sealing system of floating roof tank is large-scale storage tank safe operation
Weakest link.Oil tank sealing leak also results in the evaporateing into atmosphere of a large amount of organic gas, seriously polluted environment, together
When also cause a large amount of losses of oil product, economic benefit is greatly affected.
With the implementation of National Environment Policy Act, to the increasingly strict of air environmental pollution improvement, in July, 2015 starts to hold
In capable " petro chemical industry pollutant emission standard " GB 31571-2015, it is desirable that discharge gas in non-methane total hydrocarbons content not
Greater than 120mg/m3.Therefore volatilizing loss of the oil product in storage and transportation link is greatly decreased, VOC is made to realize that qualified discharge becomes when business
It is anxious.
Reliable floating roof sealing device can effectively prevent the evaporation of oil gas in storage tank, reduces oil and gas leakage loss, guarantees oil
Quality reduces the hydrocarbon content in floating roof, reduces environmental pollution, avoid a possibility that on fire of being struck by lightning, so that it is guaranteed that storage tank
Safe operation and clean manufacturing, economic benefit and social benefit are significant.
Therefore, it is necessary to carry out VOC comprehensive treatment to storage tank while not only solving safety problem but also to solve from watershed management
Certainly problem of environmental pollution.Floating roof spring-piece type high-efficiency seal structure, strong with its compensation ability, leakproofness effect is good, can greatly subtract
The volatilizing loss of few oil gas, satisfaction reaches environment protection emission requirement, while also solving security risk.Floating roof tank is can effectively reduce
Exploding and firing accident risk reduces oil product volatilizing loss, improves tank field surrounding enviroment.
Oil storage tank seals status:
Refinery, the country and oil depot are more using bellows filling sealing at present, by sealing band filling sponge material, are mounted on
In floating roof and tank skin gap, realize sealing when gap changes between floating roof and tank skin to reduce Loss of Oil Evaporation.?
In operational process, part floating roof tank sealing leak problem is more serious, damaged sealing band many places, oil inlet and tank occurs
The partially sealed not tight phenomenon of wall, the circumferential spatial joint clearance size between pontoon and tank skin is uneven, and gap has often exceeded rule
The backlash compensation requirement of fixed ± 100mm, affects the sealing effect of oil tank.Gap size smaller part, soft seal part by
It squeezes again, causes to seal shearing of the band by sealing supporting plate and tank skin, band breakage, oil inlet phenomenon occur；Gap larger part,
Pasta cannot be completely covered in sealing, do not have sealing function, not only oil and gas loss was caused to increase, but also easily becomes the source of fire explosion
Head.

Film, one end of the elastomeric composition plate are connected with floating plate, and the side of the floating plate is equipped with floating plate margin plate, the elastomeric composition plate
It is bolted on floating plate margin plate, one end of the anti-aging sealing film of oil resistant, which extends, wraps floating plate margin plate.
Further, the anti-aging sealing film of the oil resistant is bolted on together with floating plate margin plate.
Further, the elastic metal sheet is with a thickness of 0.5~1mm, 200~300mm every piece wide, the elastic metal sheet
It is connected as one by overlapping mode, and is arranged around floating plate.
Further, the anti-aging sealing film of the oil resistant is one whole film.
Further, the elastomeric composition plate is adjacent to the tank skin always with required sealing device.
Further, the floating plate can move horizontally on liquid level, and swim on liquid level always.
The utility model has the following beneficial effects:
The utility model structure is simple, easy to use, and metallic elastic plate is bonded with tank skin, when floating plate moves horizontally, tool
There is compensating action, and sealing film extends to floating plate margin plate, good seal performance reduces the volatilizing loss of oil gas, guarantees oil product
Quality reduces the hydrocarbon content in floating roof, reduces environmental pollution, floating plate can be according to the lift in height of liquid level, to make metal
The phenomenon that elastic plate and tank skin relative friction occur in liquid internal, will not generate electrostatic or frictional sparking, uses peace
Entirely, accident rate is reduced.
