Description
Technical field
The present invention relates to a kind of Full connected flexible light weight rubber floating plate and its applications.
Background technique
VOC (volatile organic matter) discharge of domestic atmospheric storage tank during operation causes environmental pollution, this gives petrochemical industry
Enterprise causes very big environmental protection pressure, in addition, oil gas gathers also to cause to tank field and fires very much risk greatly in storage tank, it is such as close
Ferrous sulfide incidents of spontaneous combustion etc. in a lot of External floating roof tank floating plate sealing ring blast accidents of year generation, internal floating roof tank lightning stroke or tank
Incidents of spontaneous combustion causes heavy economic losses.
In this regard, domestic enterprise has had been sought to a variety of counte-rplan, such as changing ring structure reduces the oil of floating plate sealing ring
Storage tank gas phase connection is carried out oil-gas closed processing, is disposed using device for recovering oil and gas, these technical measures are all by gas volatilization
The discharge of storage tank VOC can not be eliminated from the root, not be optimal economic security additionally, it is also possible to increase tank field risk
Counter-measure.VOC emission to have its source in pasta exposed in an atmosphere, oil gas molecule can free diffusing to free surrounding space.Outside
There is a large amount of VOC source of leaks in floating roof tank, internal floating roof tank and Dome roof tank, such as floating plate sealing ring, the seam of floating plate attachment
Venthole etc. at the top of gap, tank skin.The diffusion admittance of these completely cut off VOC molecules is the basic of thorough elimination VOC emission.
" float disk in oil tank seal failure reason and pre- of Nie's generation congruence in " Oil & Gas Storage " (2011,30 (6): 468-470)
Anti- measure " in point out that the positions such as floating plate cover board faying surface gap, seal capsule, catheter flange are the major sources of leakage, in tank
VOC emission cannot be eliminated from the root." the inner floating roof in " environmental science " (2013,34 (12): 4712-4714) such as Wu Hongzhang
Storage tank it is small breathing effect on environment process analysis " in point out that a principal element of inner floating roof VOC loss through breathing is floating plate
Sealing effect, the oil and gas loss of floating plate occur mainly at the ring type seal between floating plate and tank skin, the aging and change of floating plate
Shape is also to aggravate the major reason of VOC leakage in tank.Chen Hong " passes through " Oil & Gas Storage " (2010,29 (11): 874-876)
Petroleum vapor recovery solve gas-liquid loss through standing " in point out, the gas-phase space of each storage tank is connected, be arranged petroleum vapor recovery system
System, the measure although can solve the problems, such as that VOC is lost in tank to a certain degree, and cost of investment is high, it is slow to produce effects, cost of equipment maintenance
Height, for device for recovering oil and gas in operation there is also risk is fired, the connection of gas-phase space does not eliminate the exposed volatilization face of oil plant,
VOC does not eradicate source of leaks.
Summary of the invention
The first technical problem to be solved by the present invention is the problem that sealing effect is poor in the prior art, is provided a kind of new
Full connected flexible light weight rubber floating plate, have the advantages that sealing effect is preferable.The second technical problem to be solved by the present invention
Be to provide it is a kind of with solve the technical issues of one of corresponding Full connected flexible light weight rubber floating plate application.
One of in order to solve the above problem, The technical solution adopted by the invention is as follows: a kind of Full connected flexible light weight rubber is floating
The edge of disk, including top rubber film, aerated capsule, side rubber membrane, immobilising device, the floating plate is solid by side rubber membrane
It is scheduled on storage tank shell inner side, top rubber film lateral arrangement is located at top rubber film in tank inside space, aerated capsule
Connect down and with top rubber film, the Full connected flexible light weight rubber floating plate is constituted, under floating plate upper surface diameter is greater than
Surface diameter, and floating plate upper surface diameter is less than tank diameter, the gross area of the aerated capsule is the top rubber film gross area
20~80%.
In above-mentioned technical proposal, it is preferable that rubber membrane is made of the splicing of muti-piece rubber membrane, and seam crossing needs to seal, and meets
Intensity requirement.
In above-mentioned technical proposal, it is preferable that aerated capsule is strip, is evenly arranged under top rubber film.
In above-mentioned technical proposal, it is preferable that when the side rubber membrane and tank skin and floating plate edge at rubber membrane both ends are fixed, need
Using metal stator, gasket and bolt, guarantee bearing's sealing of rubber film edge, and there are enough support strengths.
In above-mentioned technical proposal, it is preferable that one end of side rubber membrane is fixed on tank skin circumference, is welded at fixed height
Fixed metal block is connect, retainer plate uses rectangular angle bar, and outer wall carries out preservative treatment.
In above-mentioned technical proposal, it is preferable that floating plate upper surface diameter is the 1.2~1.3 of lower surface diameter；Floating plate upper surface
Diameter is the 0.80~0.90 of tank diameter.
In above-mentioned technical proposal, it is preferable that aerated capsule is identical as rubber membrane material, and aerated capsule and rubber membrane are passed through
The rubber membrane of the side rubber membrane at tank skin edge and bottom surface is finally combined together by glue and high-temperature soldering, and formation one is complete
Whole closed flexible rubber film.
In above-mentioned technical proposal, it is preferable that rubber membrane uses the nitrile rubber of film thickness 2mm.
In above-mentioned technical proposal, it is preferable that gasket is rubber sheet gasket, and rubber sheet gasket periphery is equipped with metal stator.
In above-mentioned technical proposal, it is preferable that first the side rubber membrane of floating plate vertical direction is sequentially fixed on tank skin, is adopted
It is fixed and is sealed with bolt and gasket, connected rubber membrane lap is used for seam；The rubber membrane fixed installation of tank skin terminates
Afterwards, successively joint seal is carried out to adjacent rubber membrane.
In order to solve the above problem two, The technical solution adopted by the invention is as follows: a kind of Full connected flexible light weight rubber is floating
The application of disk, in floating roof tank seal.
Liquid level is completely covered by the flexible nature and natural buoyancy of its own in the flexible rubber floating plate of this patent, thoroughly disappears
In addition to the volatilization face of storage medium, it is empty that gas phase in tank caused by storage tank Big and Small Breath is met with the free floating of flexible rubber film
Between volume change demand, pasta and extraneous channel have been cut off, thus storage tank VOC caused by completely eliminating because of liquid level volatilization
Discharge.This patent compared with prior art, has the following advantages: (1) completely eliminating the oil gas volatilization in tank, avoid environment dirt
Dye；(2) oil gas for eliminating gas-phase space in tank gathers, and eliminates storage tank and fires risk.(3) oil product is eliminated to top half
The corrosion of tank skin and tank deck；(4) since flexible floating plate is to be fully sealed, and floating plate thickness very little, it is possible to increase effective appearance of storage tank
Product, improves the maximum storage liquid level of storage tank.It (5) is only aerated capsule and oil due to the gas-phase space very little of flexible floating pan bottom
Space between face, so floating plate can drop down onto tank bottom completely, increase the handling capacity of storage tank, achieve when storage tank outside emptying
Preferable technical effect.
