Description
Technical field
The present invention relates to a kind of safety protecting method for floating roof tank.
Background technology
After current floating roof tank floating plate landing, there is very big oil-gas space between floating plate and liquid level, the space length is past
Toward between 1.8-2m.As pasta declines, floating plate bottom will suck large quantity of air, form air mixture, run into incendiary source very
May explode.CN201120400005.5 is related to a kind of sealing of the new floating roof tank floating plate with datonation-inhibition function to fill
Put, including once sealing device, secondary sealer and block blast-proof materials, block blast-proof materials filling once sealing device and
Cavity between secondary sealer, is wrapped up and is fixed on floating plate by woven wire.
Most enterprises typically require that floating plate can not land, but this can cause the medium of floating plate bottom cannot be defeated outward, cause
Tank volume utilization rate is low, and security is poor.
The present invention targetedly solves the problem.
The content of the invention
The technical problems to be solved by the invention are that tank volume utilization rate is low in the prior art, easily suck air, safety
Property difference problem, there is provided a kind of new safety protecting method for floating roof tank.The method is used for External floating roof tank and interior floating
In the storage tank of top, have the advantages that tank volume utilization rate is high, it is good to be difficult suction air, security.
To solve the above problems, the technical solution adopted by the present invention is as follows：A kind of security protection side for floating roof tank
Method, the soft floating plate of the rubber is fixed on the metal floating plate bottom of floating roof tank using rubber strip, and the surrounding of the soft floating plate of rubber is led to
Cross fixture and be fixed on metal floating plate bottom, rubber strip has aerification function, and the surrounding and center framework of rubber strip are using inflation
Pipe, other positions are mounted directly on the pasta in storage tank using the diaphragm for being not required to inflation, after rubber strip inflation, to circumference side
Face is extended, and is fitted until with tank skin, and pasta is separated with metal floating plate；Before metal floating plate starts to float, by the soft floating plate of rubber
Interior gas is released, and is fixed on metal floating plate, and then the soft floating plate of rubber is to be fluctuated with metal floating plate, floating in metal
When disk is floated, the rubber strip is non-aerating, and pasta is floated on metal floating plate, after metal floating plate lands, is floated by being located at metal
The inflation inlet on disk top is inflated in rubber strip, and unclamps the fixture between metal floating plate and rubber strip, allows rubber strip freedom
Float on pasta, and decline with pasta, through the soft floating plate of rubber, through part uses rubber tape seals, fills the supporting leg of metal floating plate
After gas, soft floating plate glides along supporting leg, declines with pasta.
In above-mentioned technical proposal, it is preferable that the fixture is bolt.
This patent sets the soft floating plate of inflated rubber by metal floating plate bottom, and the inflated rubber that also can be used alone is soft floating
Disk, it is lifted with pasta, can drop down onto very low position, improves tank volume utilization rate, it is to avoid between pasta and floating plate
Oil-gas space is formed, security is good, achieves preferable technique effect.
Brief description of the drawings
Fig. 1 is the soft floating plate schematic diagram of inflated rubber of the present invention.
Fig. 2 is the schematic diagram before the soft floating plate inflation of inflated rubber of the present invention.
Fig. 3 is the schematic diagram after the soft floating plate inflation of inflated rubber of the present invention.
In Fig. 1~Fig. 3, the soft floating plate air-filled pore of 1 inflated rubber；The soft floating plate of 2 inflated rubbers；3 rubber floating plate diaphragms；4 floating plates
Supporting leg passes through mouth；The soft floating plate fixture of 5 inflated rubbers；6 metal floating plates；7 metal floating plate supporting legs；8 tank skins.
Below by embodiment, the invention will be further elaborated, but is not limited only to the present embodiment.
Specific embodiment
【Embodiment 1】
One soft floating plate of inflated rubber is set in the bottom of metal floating plate, the supporting leg of metal floating plate runs through soft floating plate, plays
The effect of guiding.The surrounding of soft floating plate is fixed on metal floating plate bottom by fixture, and the air-filled pore of soft floating plate is located at metal and floats
Disk top is extended to outside tank.It is non-aerating in soft floating plate when metal floating plate is floated, it is close to metal floating plate bottom.In metal
After floating plate landing, inflated in rubber floating plate by air-filled pore, opened until soft floating plate is fully expanded, and be brought into close contact with tank skin,
The fixture of soft floating plate and metal floating plate is unclamped, the soft floating plate of inflated rubber is freely dropped down onto on pasta by Action of Gravity Field, and with pasta
Float up and down.
Before metal floating plate starts to float, gas in the soft floating plate of rubber is released, and be fixed on metal floating plate, so
The soft floating plate of rubber is to be fluctuated with metal floating plate afterwards.
After metal floating plate bottom addition inflatable rubber floating plate, after floating plate landing, inflated rubber floating plate is floated and pasta,
Oil-gas space between rubber floating plate and metal floating plate can eliminate more than 98%, and only rubber floating plate passes through the supporting leg of metal floating plate
There is the possibility of oil and gas leakage at place, the gap between rubber floating plate and tank skin, after inflated rubber floating plate is fully inflated,
The soft floating plate of rubber can be brought into close contact with tank skin, the gap between soft floating plate and tank skin is reduced to it is minimum, and rubber floating plate with gold
Rubber seal is used at category supporting leg, oil and gas leakage rate herein can be also substantially reduced.Therefore, after the landing of metal floating plate, metal
The possibility that floating plate bottom occurs oil gas explosion is almost eliminated, and substantially increases the safety operation level of floating roof tank.Floating plate falls
Behind ground, pasta can continue to decline, and can so improve the utilization rate of dischargeable capacity in tank, and by taking 100,000 storage tanks as an example, tank skin is highly
22m, actually fills height about 20m, floating plate floor-type support height 2.2m, before the soft floating plate of the inflated rubber is not installed, storage tank
Minimum normal level be 2.2m, liquid level runs only between 2.2m-20m, operation spacing be 17.8m；And inflated rubber is installed
After soft floating plate, the minimum normal level of storage tank is down to 0.5m, and operation spacing is 19.5m, and tank appearance increased 11%, and this can be carried significantly
The utilization rate of storage tank high, reduces the investment of tank field.
The soft floating plate of the inflated rubber can be applied not only to External floating roof tank, can also apply internal floating roof tank.
