Abstract
The invention discloses a flame-proof and explosion-proof safety device for primary and secondary sealing spaces of an external floating-roof oil storage tank. The flame-proof and explosion-proof safety device comprises an inflatable soft capsule arranged in the primary and secondary sealing spaces of the external floating-roof oil storage tank, wherein the inflatable soft capsule is connected with an inflating/exhausting joint; in the event of inflating the cavity of the inflatable soft capsule, the inflatable soft capsule is expanded by gas till the whole primary and secondary sealing spaces of the external floating-roof oil storage tank are fully filled with the expanded inflatable soft capsule; simultaneously, a secondary sealing part of the storage tank is opened in an ejecting manner, so that a certain clearance for discharging residual oil gas is formed between the end part of the secondary sealing part and the inner wall of the storage tank. According to the invention, the inflatable soft capsule is arranged in the primary and secondary sealing spaces of the external floating-roof oil storage tank, so that the whole primary and secondary sealing spaces are fully filled with the inflatable soft capsule after the soft capsule is inflated and expanded, and therefore, space for containing oil gas hardly exists in the primary and secondary sealing spaces; because the oil gas space is fully occupied by the inflatable soft capsule, the external floating-roof oil storage tank cannot be flamed and exploded even being struck by lightning, and therefore, flame-proof and explosion-proof safety protection for the primary and secondary sealing spaces of the external floating-roof oil storage tank is realized.
Description
Technical field
?the invention belongs to security against fire technical field, particularly the anti-safety device that fires of a kind of outer floating roof petroleum storage tank first and second seal cavity.
Background technology
Crude oil is as inflammable and explosive dangerous goods, and the oil storage method of scale must bring huge challenge to safety in production.World wide inner storage tank fire accident occurs a lot of, is that the oil-gas space of outer floating roof petroleum storage tank first and second seal cavity is because the effect of thunderbolt or static causes mostly.
This is the General Construction of now domestic and international outer floating roof petroleum storage tank for outer floating roof petroleum storage tank first and second seal cavity, also be the present situation that can not avoid and change in design, and the many factors such as oily volatilization are accelerated in the stirring in gasification, charge of oil or the emptying of the fluid of formation reasons such as day and night temperature, make outer floating roof petroleum storage tank first and second seal cavity certainly exist oil gas, thereby make outer floating roof petroleum storage tank first and second seal cavity certainly exist the potential safety hazard of oil gas detonation.
At present, common processing method mainly contains following two kinds:
One, when once the oil gas of outer floating roof petroleum storage tank first and second seal cavity causes after storage tank detonation because of factors such as thunderbolt, static, the devices such as employing fire-fighting foams big gun etc. are puted out a fire to save life and property to it, this passive type protection is generally used for the initial fire disaster of putting out a fire to save life and property, once the intensity of a fire develops into after big fire, be often difficult to put out a fire to save life and property and control.
Two, for the oil-gas space of outer floating roof petroleum storage tank first and second seal cavity, adopt the unreactable gass such as nitrogen injection, carbon dioxide, externally the oil gas of floating roof petroleum storage tank first and second seal cavity carries out inerting, thereby reduction gas concentration, make this space in a safe condition, but its corresponding apparatus structure is comparatively complicated, and operation cost is high.
Summary of the invention
The object of the invention is to: for the problem of above-mentioned existence, provide a kind of safe and reliable and economic and practical outer floating roof petroleum storage tank first and second seal cavity the anti-safety device that fires.
Technical scheme of the present invention is achieved in that a kind of outer floating roof petroleum storage tank one, the anti-safety device that fires in secondary seal space, it is characterized in that: comprise and be arranged on one of outer floating roof petroleum storage tank, the soft capsule of inflation in secondary seal space, the soft capsule of described inflation is connected with fill/exhaust joint, when to the soft capsule inner chamber inflation of described inflation, gas makes to inflate soft capsule and expands, until the soft capsule of inflation after expanding fills up whole outer floating roof petroleum storage tank one, secondary seal space, the secondary seal part of storage tank is backed down simultaneously, make to form certain interval between secondary seal part end and reservoir walls and squeeze remaining oil gas.
Outer floating roof petroleum storage tank first and second seal cavity of the present invention is anti-fires safety device, and the shape of the soft capsule of inflation and the shape of outer floating roof petroleum storage tank first and second seal cavity after expanding described in it match.
Outer floating roof petroleum storage tank first and second seal cavity of the present invention is anti-fires safety device, and fill described in it/exhaust joint one end is connected with the built-in fitting that embeds the soft capsule of inflation, and its other end is passed by the secondary seal part of storage tank.
Outer floating roof petroleum storage tank first and second seal cavity of the present invention is anti-fires safety device, and the fill/exhaust joint of inflating soft capsule described in it adopts quick joint form.
The anti-safety device that fires of outer floating roof petroleum storage tank first and second seal cavity of the present invention, described in it, inflate soft capsule and can be divided into separate some sections, the soft capsule of inflation of each section is respectively arranged with the corresponding fill/exhaust joint connecting with it, and the soft capsule of inflation of described each section jointly fills up whole outer floating roof petroleum storage tank first and second seal cavity after inflation.
Outer floating roof petroleum storage tank first and second seal cavity of the present invention is anti-fires safety device, and described in it, the once sealing of outer floating roof petroleum storage tank is soft seal.
Outer floating roof petroleum storage tank first and second seal cavity of the present invention is anti-fires safety device, and described in it, the once sealing of outer floating roof petroleum storage tank is mechanical sealing member.
The present invention is by arranging the soft capsule of inflation in floating roof petroleum storage tank first and second seal cavity outside, make to inflate soft capsule and after inflation, be full of whole first and second seal cavity, make almost not have in first and second seal cavity of outer floating roof petroleum storage tank the space of oil gas.Because the soft capsule of inflation has filled up the oil-vapo(u)r space, even if be struck by lightning like this, can there is not detonation yet, thereby realize the anti-safety guard-safeguard that fires of external floating roof petroleum storage tank first and second seal cavity.The present invention adopts the soft capsule of safe inflation, and sealing effectiveness retentivity is good, easy for installation, simple in structure, be suitable in engineering and apply.
