Description
Technical field
The utility model belongs to the sealing of floater, and especially one can ensure that oil tank initiatively starts fire extinguishing when unexpected on fire or abnormal high temperature, avoids the active suppression type once sealing device of generation tank fire.
Background technology
Floater mouth area is larger, very easily cause the volatilization of oil in tank, for solving this kind of problem, in floating storehouse, outer edge arranges sealing arrangement, i.e. once sealing device, realize sealing the tank mouth of outside, floating storehouse, floater is exposed in open-air atmosphere more simultaneously, very easily be subject to the impact of environment, when running into unexpected on fire or a small amount of spark or even abnormal high temperature, once sealing device can not play fire insulation effect completely, very easily causes that oil tank large area is on fire even explodes, and causes the loss or injury that can not recover.For solving this kind of problem, the patented technology of pre-blast protection and fire (a kind of seal ring reduction of fractions to a common denominator explosion suppression device of floater has been had in prior art, the patent No. 201110057960.8), main technique methods in the present invention utilizes inertia non-flammable compressive gas the air of once sealing device upper space between floating storehouse and oil tank or some oil gas to be driven away, play a fire preventing or explosion-proof object, can also pass into but combustion gas body to seal cavity by fast speed after fire occurs simultaneously, play the effect of fire extinguishing.But the Meteorological of this device is large, and be applicable to large oil tank use more, also need when mounted to coordinate large-scale gas reservoir or gas generating unit to use, floor area is large, field of application is narrow, and this device is when suppressing, the gas of seal cavity is needed to discharge, a small amount of oil gas etc. is also had in these gases, these exhaust of oil are in air, very easily cause the secondary pollution of air or run into high temperature or spark appearance burning etc. in atmosphere, so just cause secondary disaster, so, in prior art, this presses down sudden and violent device and seldom uses, well do not play and press down the sudden and violent or effect of riding calamities of putting out a fire.
In currently available technology, oil tank fire extinguishing measure mainly still adopts fire-fighting fire extinguishing expense way afterwards, after namely fire occurs, foam seal liquid injects in tank in fire brigade, formed between tank skin and fire-fighting foams baffle plate and cover, starvation, thus the object reaching fire extinguishing.The subject matter that this fire-fighting mode exists is that warning attack time is long, and when finding that fire is on the scene to fire fighter, the condition of a fire occurs, difficulty is brought to fire extinguishing, thus prolongation attack time, cause larger Loss of Life and property, also easily injure fire fighter.

The beneficial effect of technical solutions of the utility model is: a kind of floater active suppression of the utility model type once sealing device technique scheme adds fire extinguisher plant in the annular space that once sealing and the secondary seal of floater are formed, fire extinguisher plant is for comprising fire extinguisher and put out a fire starter gear and firing-fighting medium producer, firing-fighting medium producer automatically can be responded to the temperature in annular region and have the flames of anger, can start when presence of fire, realize fire extinguishing, change the mode of warning and fire fighter's fire extinguishing after presence of fire in prior art, also change in prior art simultaneously and adopt for a long time to the mode of filling unreactable gas in annular region.
The utility model floater active suppression type once sealing device has the following advantages:
1, device overall volume is little, easy for installation, and cost drops into low, applied widely, being in sleep state, consuming energy little when not having presence of fire;
2, adopt fire extinguisher and the direct extinguish open flame of firing-fighting medium, avoid the air containing oil gas to enter in air and cause secondary pollution even to cause secondary disaster at the fire of oil tank perimeter;
3, fire extinguisher plant entire system is provided with and automatically responds to starter gear, when presence of fire, automatically starts, fire extinguishing there is instantaneity, can not cause the large area of oil tank on fire or blast, ensure that property and personal safety.
