Description
Technical field
It is cellular interior more particularly to a kind of light oil tank the present invention relates to gas of oil storage tank loss Treatment process field
Floating plate oil and gas loss comprehensive treatment device.
Background technology
During oil movement and storage, due to being limited by technology and relevant device, crude oil and light oil (such as vapour
Oil) in part light components be easily emitted in air, produce serious evaporating loss.According to relevant statistical material, 70
Beginning of the eighties age end, the oil loss of China's oil plant storage and handling facility account for the 0.3%~0.45% of crude runs, wherein,
The evaporating loss of oil product accounts for more than 60% in storage tank.In recent years, due to the application of floating roof tank and internal floating roof tank, floating plate equipment
Update, and take other Reducing Consumption Measures, oil loss declines year by year, but floating plate edge seal and attached set
Shi Shang, however it remains oil gas leak point, evaporating loss phenomenon are not prevented fundamentally, as country administers to VOCS
Dynamics increase, the sealing effectiveness of existing floating plate can not meet to require.
The sealing of existing floating plate is smaller to tank body defect compensating ability, when tank diameter deviation is larger, tank skin flatness compared with
When low, verticality of stand column has deviation, the ring packing of floating plate edge and column can not make up the above completely by device SLD
Deviation, easily there is local leakage phenomenon, cause oil gas volatilization to be lost.This exterior float disc standard module gap, anti-rotation device,
Manhole, sampler, protection negative pressure eliminating device and column inner space exist with can not all avoiding in design oil-gas space and
Oil gas dissipates phenomenon, and this phenomenon is persistently undoubtedly added oil product volatilizing loss and potential safety hazard.
The present invention is directed to leakage problem existing for existing floating plate and carries out the comprehensive regulation, is filled using air bag and covering material
Floating plate edge slot and column edge slot, can compensating tank to greatest extent using gas fluidity and expansile feature
Body diameter deviation, tank skin flatness deviation and verticality of stand column deviation, oil-gas space is blocked, reduce oil gas volatilization, seal simultaneously
Effect monitoring facility can realize that SLD running situation monitors in real time, seal nitrogen online compensation, ensure sealing effectiveness,
Reduce oil gas volatilization.In addition, the sealing skill of the affiliated facility such as manhole, sampler, protection negative pressure eliminating device and column inner space
Art is improved so that floating plate is made something perfect even more perfect, and VOCS is greatly lowered.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of loss of light-end products gas of oil storage tank to integrate
Controlling device.
The technical solution adopted in the present invention is that the SLD of floating plate is upgraded into a kind of air sac sealing facility, and
Seal reconstruction is done to the affiliated facility that there may be oil gas volatilization on floating plate, fundamentally solves gas of oil storage tank dissipation
Problem.
The present invention include floating plate edge seal facility, column edge SLD, floating plate sealing effectiveness monitor and control facility and
Inside column, the sealing in standard module gap, anti-rotation device, manhole, the affiliated facility such as sampler and protection negative pressure eliminating device
Transform facility.Described floating plate edge seal facility and column edge SLD is connected to floating plate sealing effectiveness monitor and control facility
On, the pressure conduction of pressure bladder enters monitor and control facility, realizes sealing effectiveness monitoring and online pressure compensation.Described floating plate is attached
Belong to facility SLD by Optimizing Reconstruction device structure, eliminate oil-gas space, strengthen sealing, reduce oil product volatilization loss.
In summary, the present invention is targetedly transformed in all institutes of storage tank floating plate leak point that may be present, and in fact
Existing pressure bladder pressure monitor, it is ensured that sealing effectiveness does not retreat.Seal reconstruction on affiliated facility so that whole floating plate brocade
On add flower, VOCS discharge capacitys are greatly lowered, reach the purpose of energy-conserving and environment-protective.

- A kind of 10. light oil tank oil and gas loss comprehensive treatment device according to claim 1, it is characterized in that described is anti- Rotating device SLD increases rubber seal on floating plate, and flange transformation of the way structure fixes rubber seal so that anti-rotational Oil and gas loss is completely eliminated in device in the process of running.
- A kind of 11. light oil tank oil and gas loss comprehensive treatment device according to claim 1, it is characterized in that described people Hole connects liquid SLD sealing-plug under cover plate, and sealing-plug thickness is consistent with floating plate, and sealing-plug side of dehiscing is cambered design, protects Demonstrate,prove smooth without hindrance during cover plate switch, cover plate dehisces to carry at the top edges of side buckle, and helper is that staff provides to rise and led to Road, the opening and closing operations that button facilitates cover plate for manhole being put forward, cover plate dehisces side with there is the cover plate outer of horizontal extension at side top edges, For cover plate in the closed state, cover plate outer is overlapped on casing outer, there is rubber blanket the edge that floating plate contacts with lapping plate.Originally set Apply and effectively eliminate below cover plate for manhole the oil-gas space between pasta, prevent oil gas volatilization, reduce exhaust of oil, reduction safety Hidden danger.
- A kind of 12. light oil tank oil and gas loss comprehensive treatment device according to claim 1, it is characterized in that described takes Sampling device connects liquid SLD and is connected to the cover plate at floating plate edge provided with one end, and cover plate dehisces to be provided with the top surface edge of side to carry Button, lifting rope is fixed on to carry and buckles, and cover plate dehisces have the pinch of hang plate obliquely, hang plate and floating plate above the floating plate edge of side For 60 °, there is sealing-plug cover plate lower section, and sealing-plug thickness is consistent with floating plate, has horizontal extension at cover plate side top edges Lapping plate, for cover plate in the closed state, lapping plate is overlapped on floating plate edge, there is rubber the edge that floating plate contacts with lapping plate Pad.This facility realizes that sampler connects liquid-tight envelope entirely, eliminates safe hidden trouble, and reduces exhaust of oil.
- A kind of 13. light oil tank oil and gas loss comprehensive treatment device according to claim 1, it is characterized in that described is negative Pressure cancellation element connects liquid SLD and is provided with vent seal plug, and vent seal beyond the Great Wall provided with diameter more than sealing-plug take by edge Fishplate bar, lapping plate eliminate cylinder outer with negative pressure and contacted, and the contact area has rubber blanket, and vent seal plug disappears provided with negative pressure below Except supporting leg, negative pressure elimination leg length is longer 90mm than floating plate supporting leg, and negative pressure eliminates leg diameter and is slightly less than floating plate supporting leg, and negative pressure disappears Except cylinder is connected with floating plate girder by fastener.
