Description
Technical field
The present invention relates to oil storage tank sealing techniques, connect liquid floating plate and its implementation entirely more particularly to one kind is novel.
Background technique
The floating plate sealing technique of oil storage tank sealing technique, especially floating roof tank is the key technology of oil product storage.It is existing
Some floating plate integral sealing technologies include following several types:
1) non-to connect liquid floating plate entirely.
Floating plate is floated on by multiple floating drums in storage tank on medium, therefore there are the gas compartment, oil between floating plate and medium
Product can be evaporate into this space, then be volatilized outward from the component of this spatial transmission floating plate manhole or connector etc, cause to let out
Dew volatilization, and revealing area is that entire exposure pasta is being revealed, volatile quantity is very big, thus its sealing performance be not so good as in storage tank
What medium completely attached to connects liquid floating plate entirely.
2) liquid aluminium floating plate is connect entirely.
Fig. 1 is the structure chart that the use of the prior art connects the storage tank of liquid aluminium floating plate entirely, as shown in Figure 1, connecing liquid aluminium floating plate entirely
It can be only applied to internal floating roof tank, cellular floating plate, box floating plate etc. can be divided into according to floating box structure；According to its installation side
Formula can be divided into plug-in type floating plate, spliced floating plate etc..Therefore, because its floating plate is assembling, no matter which kind of floating plate is used,
It is required to be handled using seal means between buoyancy tank and buoyancy tank, buoyancy tank and weighing apparatus/vertical beam, to guarantee its leakproofness, but apply
In work/operational process, it is difficult to ensure that the sealing effect.
The poor corrosion resistance of aluminium floating plate is easy to happen chemical reaction since the property of aluminium is active, although aluminum alloy surface meeting
Passivation layer is formed, but still can not be applicable in some corrosive liquids.
Aluminium floating plate is not suitable for outer floating roof floating plate.Outer floating roof floating plate is due to needing to consider that drainage problem, floating plate are typically designed
It is low between edge senior middle school, centre install drainage arrangement, but aluminium alloy floating disk because the basic thickness of all modules it is identical, can not
Applied to outer floating roof floating plate.
3) liquid steel floating plate is connect entirely
Fig. 2 is the tank structure figure using steel floating plate of the prior art；As shown, connecing liquid steel floating plate entirely both can be used for
Internal floating roof tank can be used for External floating roof tank.But it is less applied to internal floating roof tank, is primarily due to its welding steel ruler
Very little (1500mm) is greater than storage tank manhole size (600mm), therefore, when it is applied to internal floating roof tank, since steel is steel plate
Integral solder forms, and under the premise of not destroying storage tank, can not replace, and it is also more difficult to repair, so it is floating inside to limit steel floating plate
The application of storage tank is pushed up, and steel floating plate needs to get angry in maintenance, is easy initiation accident.
Connecing liquid steel floating plate entirely mainly uses steel plate to weld mono-/bis-disk compartment-type floating plate, and floating plate own wt is heavier, has
Following problem: when encountering floating plate and acutely shaking (such as earthquake), tank skin can be hit and cause storage tank shell severely deformed；And when floating
When disk lands, since supporting leg load is larger, buckling is generated.
The poor corrosion resistance of steel floating plate is easy to happen chemical reaction since steel is more active, larger to requirement for anticorrosion,
And some corrosive liquids cannot use steel floating plate.
Therefore, the poor corrosion resistance of existing steel floating plate and aluminium floating plate, seal it is poor, cannot simultaneously be suitable for internal floating roof tank with
External floating roof tank, it be problem to be solved that it is inconvenient, which to install to tank body " cutting open the chest " when construction,.
