Abstract
The invention relates to a safety protection method for a floating roof storage tank, and mainly solves the problems that in the prior art volume utilization ratio of a storage tank is low, air is prone to inhaling, and the safe performance is poor. According to the safety protection method for the floating roof storage tank, a rubber soft floating plate is fixed to the bottom of a metal floating plate of the floating roof storage tank by using a rubber belt; when the metal floating plate floats, the rubber belt is not inflated and floats on an oil level along with the metal floating plate; when the metal floating plate falls on the ground, the rubber belt is inflated through an inflation inlet formed in the upper portion of the metal floating plate, a fixed part arranged between the metal floating plate and the rubber belt is loosened, the rubber belt floats on the oil level freely and is descended along with the oil level, a landing leg of the metal floating plate penetrates through the rubber soft floating plate, and the penetrating location is sealed by the rubber belt; after the rubber belt is inflated, the soft floating plate slides downwards along with the landing leg. By means of the technical scheme of descending along with the oil level, the problems are solved better, and the safety protection method can be used for an external floating storage tank and an internal floating storage tank.
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 lands, there is very large oil-gas space between floating plate and liquid level, this space length is often between 1.8-2m.Along with pasta declines, bottom floating plate, will large quantity of air be sucked, and form air mixture, run into ignition source and probably blast.CN201120400005.5 relates to a kind of novel sealing arrangement with the floating roof tank floating plate of datonation-inhibition function, comprise once sealing device, secondary sealer and block blast-proof materials, the cavity between once sealing device and secondary sealer filled by block blast-proof materials, wrapped up and be fixed on floating plate by wire gauze.
Most enterprises General Requirements floating plate can not land, but this can cause the medium bottom floating plate cannot be defeated outward, causes tank volume degree of utilization low, poor stability.
The present invention solves this problem targetedly.
Summary of the invention
Technical matters to be solved by this invention is low, the problem that easily sucks air, poor stability of tank volume degree of utilization in prior art, provides a kind of safety protecting method for floating roof tank newly.The method is used in External floating roof tank and internal floating roof tank, have tank volume degree of utilization high, not easily suck air, advantage that safety is good.
For solving the problem, the technical solution used in the present invention is as follows: a kind of safety protecting method for floating roof tank, rubber tape is adopted to be fixed on by soft for described rubber floating plate bottom the metal floating plate of floating roof tank, the surrounding of the soft floating plate of rubber is fixed on metal floating plate bottom by connecting element, rubber tape has aerification function, the surrounding of rubber tape and center framework adopt appendix, other positions adopt the diaphragm not needing to inflate, directly fit in the pasta in storage tank, after rubber tape inflation, expand to circumference aspect, until fit with tank skin, pasta and metal floating plate are separated, before metal floating plate starts to float, gas in soft for rubber floating plate is released, and be fixed on metal floating plate, then namely the soft floating plate of rubber fluctuates with metal floating plate, when metal floating plate is floating, described rubber tape is not inflated, pasta is floated on metal floating plate, after metal floating plate lands, inflated in rubber tape by the inflation inlet being located at metal floating plate top, and the connecting element unclamped between metal floating plate and rubber tape, rubber tape is allowed freely to float on pasta, and decline with pasta, the supporting leg of metal floating plate is through the soft floating plate of rubber, through part adopts rubber tape seals, after inflation, soft floating plate glides along supporting leg, decline with pasta.
In technique scheme, preferably, described connecting element is bolt.
This patent by arranging the soft floating plate of inflated rubber bottom metal floating plate, also can be used alone the soft floating plate of inflated rubber, it is elevated along with pasta, very low position can be dropped down onto, improve tank volume degree of utilization, avoid between pasta and floating plate and form oil-gas space, safety is good, achieves good technique effect.
Accompanying drawing explanation
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 rubber; 3 rubber floating plate diaphragms; 4 floating plate supporting legs pass through mouth; The soft floating plate connecting element of 5 inflated rubber; 6 metal floating plates; 7 metal floating plate supporting legs; 8 tank skins.
Below by embodiment, the invention will be further elaborated, but be not limited only to the present embodiment.
Detailed description of the invention
[embodiment 1]
Arrange a soft floating plate of inflated rubber 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 connecting element, and the air-filled pore of soft floating plate is located at metal floating plate top or extends to outside tank.When metal floating plate is floating, do not inflate in soft floating plate, be close to bottom metal floating plate.After metal floating plate lands, inflated in rubber floating plate by air-filled pore, until soft floating plate expands completely, and fit tightly with tank skin, unclamp the connecting element of soft floating plate and metal floating plate, the soft floating plate gravitate of inflated rubber freely drops down onto on pasta, and floating up and down with pasta.
Before metal floating plate starts to float, released by gas in soft for rubber floating plate, and be fixed on metal floating plate, then namely the soft floating plate of rubber fluctuates with metal floating plate.
After adding inflatable rubber floating plate bottom metal floating plate, after floating plate lands, floating and the pasta of inflated rubber floating plate, oil-gas space between rubber floating plate and metal floating plate can eliminate more than 98%, only rubber floating plate passes through the supporting leg place of metal floating plate, there is the possibility of oil and gas leakage in the gap place between rubber floating plate and tank skin, after the complete inflation of inflated rubber floating plate, the soft floating plate of rubber can fit tightly with tank skin, gap between soft floating plate and tank skin is reduced to minimum, and rubber floating plate and metal supporting leg place adopt rubber seal, also oil and gas leakage rate herein can greatly be reduced.Therefore, after metal floating plate lands, the possibility that oil gas explosion occurs bottom metal floating plate is almost eliminated, and substantially increases the safety operation level of floating roof tank.After floating plate lands, pasta can continue to decline, the degree of utilization of effective volume in tank can be improved like this, for 100,000 storage tanks, tank skin height 22m, actually fill highly about 20m, floating plate floor-type support height 2.2m, before not installing the soft floating plate of this inflated rubber, the minimum normal level of storage tank is 2.2m, liquid level only runs between 2.2m-20m, and running spacing is 17.8m; And after installing the soft floating plate of inflated rubber, the minimum normal level of storage tank is down to 0.5m, running spacing is 19.5m, and tank appearance adds 11%, and this can improve the degree of utilization of storage tank greatly, reduces the investment of tank field.
The soft floating plate of this inflated rubber not only can be applicable to External floating roof tank, also can apply internal floating roof tank.
