Abstract
The utility model relates to a novel explosion suppression type floating plate sealing device for a floating-roof storage tank, which comprises a primary sealing device, a secondary sealing device and a separation and explosion-proof material. The separation and explosion-proof material is filled in a cavity between the primary sealing device and the secondary sealing device and wrapped by a metal mesh to be fixed onto a floating plate. The explosion suppression type floating plate sealing device is widely applicable to various oil depots of petroleum and petrochemical enterprises and large-size floating-roof storage tanks in tank fields, the problem of sealing safety of floating plate seal rings for the large-size floating-roof storage tanks is solved, operational safety of the large-size floating-roof storage tanks is guaranteed, oil volatilization and loss can be effectively reduced, and environment pollution caused by oil volatilization is reduced.
Description
Technical field
The utility model relates to a kind of sealing arrangement of floating roof tank, particularly relates to a kind of sealing arrangement of the floating roof tank that can prevent to explode.
Background technology
China's existing " Code for design of petroleum depots " requires floater should adopt secondary sealer, has both established once and the secondary double seal, and between first and second sealing annular sealed space has been arranged, and can have a certain amount of vaporizing oil-gas in this space.When there is defective in once sealing, and temperature is when bigger than higher or wind-force, and gas concentration will raise in the space in, reaches explosive limits, the formation explosion environment.Because there is explosion environment in storage tank floating plate seal ring place, during the appearance point burning things which may cause a fire disaster at the seal ring place (like thunder and lightning, static, naked light etc.), the initiation fire then of promptly can blasting.
China's floating roof tank sealed ring fire explosion frequently took place in recent years; Floating plate sealingly secure problem is very outstanding; Therefore be badly in need of large-scale floating roof tank floating roof tank floating plate sealing arrangement is improved, to solve seal ring because of the fire explosion problem of being struck by lightning or static causes.
The utility model content
The technical matters that the utility model will solve is; A kind of later-model sealing arrangement with floating roof tank floating plate of datonation-inhibition function is provided; This sealing arrangement is between existing first and second sealing, to fill a kind of block blast-proof materials; The existence of this material is arranged, can prevent first and second the sealing between space internal cause oil gas existence and fire, can effectively avoid the generation of large-scale floating roof tank floating roof tank floating plate seal ring fire explosion then.
The utility model provides a kind of datonation-inhibition type floating roof tank floating plate sealing arrangement; The once sealing device 1 and secondary sealer 2 that comprise floating plate; It is characterized in that; Said sealing arrangement has block blast-proof materials 3, fills the cavity between once sealing device 1 and the secondary sealer, is wrapped up and is fixed on the floating plate 5 by wire gauze 4.
The utility model can be widely used on all kinds of petroleum and petrochemical industry enterprise's oil depots and the large-scale floating roof tank in tank field; Solve large-scale floating roof tank floating plate seal ring sealingly secure problem; Ensure large-scale floating roof tank safe operation; Can effectively reduce the oil product volatilizing loss again, reduce the environmental pollution that the oil product volatilization causes.
The utility model not only can utilize block blast-proof materials to prevent that the floating roof tank sealed ring place from blasting when running into contingency such as static, thunderbolt, naked light because of the inflammable and explosive oil gas that exists in the cavity between once sealing device and the secondary sealer and catch fire after implementing.Simultaneously, adopt this kind floating plate sealing arrangement, can also effectively resist the volatilization of oil gas in the storage tank, reduce oil loss, make the sealing of Large Oil Tank floating plate more safe and reliable.
Description of drawings
Fig. 1 is the scheme drawing of datonation-inhibition type floating roof tank floating plate sealing arrangement, wherein,
1, once sealing device; 2, secondary sealer; 3, block blast-proof materials; 4, wire gauze; 5, floating plate.
The specific embodiment
As shown in Figure 1; The datonation-inhibition type floating roof tank floating plate sealing arrangement that the utility model relates to comprises the once sealing device 1 of floating plate, secondary sealer 2; The block blast-proof materials 3 of filling between first and second sealing, block blast-proof materials is wrapped up and is fixed on the floating plate 5 by wire gauze 4.Block blast-proof materials 3 is the materials that can not blast well known in the art.
The utility model has the advantages that and utilize block blast-proof materials to prevent the inflammable and explosive oil gas of floating roof tank sealed ring place, when running into contingencies such as static, thunderbolt, naked light, blast and catch fire because of existing in the cavity between once sealing device and the secondary sealer.Adopt this kind floating plate sealing arrangement, can also effectively resist the volatilization of oil gas in the storage tank, reduce oil loss, make the sealing of Large Oil Tank floating plate more safe and reliable.
When using the utility model, at first the once sealing device is installed on the floating plate, will be placed on the once sealing top with the block blast-proof materials of silk screen parcel then, itself and floating plate are fixed, secondary sealer is installed at last.Such floating plate sealing arrangement; Even gas concentration is in Explosive Range in the cavity between first and second sealing arrangement; Oil gas can detonation yet; Can fundamentally solve floating plate seal ring place and fire, thereby avoid the generation of floating roof tank sealed ring and even whole storage tank fire accident because of the oil gas that thunderbolt, static or naked light cause.
The utility model can be widely used on all kinds of petroleum and petrochemical industry enterprise's oil depots and the large-scale floating roof tank in tank field; Solve large-scale floating roof tank floating plate seal ring sealingly secure problem; Ensure large-scale floating roof tank safe operation; Can effectively reduce the oil product volatilizing loss again, reduce the environmental pollution that the oil product volatilization causes.
