Description
Technical field
The invention belongs to technical field of fire safety, seal space particularly to the outer floating roof petroleum storage tank first and second of one and prevent firing safety device.
Background technology
Crude oil is as inflammable and explosive dangerous goods, and the oil storage method of scale necessarily brings huge challenge to safety in production.World wide inner storage tank fire incident occurs a lot of, is that outer floating roof petroleum storage tank first and second seals the oil-gas space in space and causes due to the effect of thunderbolt or electrostatic mostly.
Outer floating roof petroleum storage tank first and second seals space, and this is the universal architecture of now both at home and abroad outer floating roof petroleum storage tank, also it is the present situation can not avoided and change in design, and the many factors such as the volatilization of oil are accelerated in the agitation in the gasification of fluid, charge of oil or emptying that the reasons such as such as day and night temperature are formed, make outer floating roof petroleum storage tank first and second seal space and certainly exist oil gas, so that outer floating roof petroleum storage tank first and second seals space certainly exists the potential safety hazard of oil gas detonation.
At present, common processing method mainly has a following two:
One, after the oil gas sealing space when outer floating roof petroleum storage tank first and second once causes storage tank detonation because of factors such as thunderbolt, electrostatic, use the devices etc. such as fire-fighting foams big gun that it is puted out a fire to save life and property, the protection of this passive type is generally used for initial fire disaster of putting out a fire to save life and property, after the intensity of a fire once develops into big fire, it tends to be difficult to put out a fire to save life and property and control.
Two, the oil-gas space in space is sealed for outer floating roof petroleum storage tank first and second, use the noble gas such as nitrogen injection, carbon dioxide, the oil gas that external floating roof petroleum storage tank first and second seals space carries out inerting, thus reduce gas concentration, make this space in a safe condition, but the apparatus structure of its correspondence is complex, and operation cost is high.
Summary of the invention
It is an object of the invention to: for the problem of above-mentioned existence, it is provided that a kind of safe and reliable and economic and practical outer floating roof petroleum storage tank first and second seals space to be prevented firing safety device.
The technical scheme is that and be achieved in that: a kind of outer floating roof petroleum storage tank one, secondary seal space is anti-fires safety device, it is characterized in that: include being arranged on the one of outer floating roof petroleum storage tank, the soft capsule of inflation in secondary seal space, the soft capsule of described inflation with fill/exhaust joint is connected, when capsule inner chamber soft to described inflation is inflated, gas makes the soft capsule of inflation expand, until the soft capsule of inflation after Peng Zhanging fills up whole outer floating roof petroleum storage tank one, secondary seal space, the secondary seal of storage tank is backed down simultaneously, make between secondary seal end and reservoir walls, to form certain interval and be expelled from remaining oil gas.
Outer floating roof petroleum storage tank first and second of the present invention seals space to be prevented firing safety device, and the shape inflating soft capsule after its described expansion and outer floating roof petroleum storage tank first and second seal the mating shapes in space.
Outer floating roof petroleum storage tank first and second of the present invention seals that space is anti-fires safety device, fill described in it/exhaust joint one end is connected with the built-in fitting embedding the soft capsule of inflation, its other end is passed by the secondary seal of storage tank.
Outer floating roof petroleum storage tank first and second of the present invention seals that space is anti-fires safety device, and the filling of its soft capsule of described inflation/exhaust joint uses hydraulic quick coupler form.
Outer floating roof petroleum storage tank first and second of the present invention seals space to be prevented firing safety device, its soft capsule of described inflation can be divided into separate some sections, each section inflate soft capsule be respectively arranged with therewith corresponding connect fill/exhaust joint, the soft capsule of inflation of described each section jointly fills up whole outer floating roof petroleum storage tank first and second after inflation and seals space.
Outer floating roof petroleum storage tank first and second of the present invention seals space to be prevented firing safety device, and the once sealing of its described outer floating roof petroleum storage tank is soft seal.
Outer floating roof petroleum storage tank first and second of the present invention seals space to be prevented firing safety device, and the once sealing of its described outer floating roof petroleum storage tank is mechanical sealing member.
The present invention arranges the soft capsule of inflation in sealing space by the most floating roof petroleum storage tank first and second, make the soft capsule of inflation be filled with whole first and second after inflation and seal space so that the space existed almost without oil gas in first and second sealing space of outer floating roof petroleum storage tank.It is filled with the oil-vapo(u)r space owing to inflating soft capsule, accordingly even when be struck by lightning, detonation also will not occur, it is achieved thereby that external floating roof petroleum storage tank first and second seals the anti-of space fires safeguard protection.The soft capsule of inflation that the present invention uses safety high, sealing effectiveness retentivity is good, easy for installation, simple in construction, is suitable at engineer applied.
