Abstract
The utility model relates to an initiative fireproof device for the inner floating roof of an oil tank. The utility model is a floating roof which can freely rise and fall following an oil surface and is composed of two folding elastomers at least and an annular floating disk which are connected together, and the elastomers and the body of the oil tank have a same center of a circle and have different diameters. Inert gases are filled among the floating roof, the tank body, and the oil surface. The whole device of the utility model is in a closed system. The device makes oil tanks store oil under the condition of the lack of oxygen and can prevent the evaporation of oil gases for overflow, and the utility model can be isolated from fire to realize fire preventing. Compared with general oil tanks with an inner floating roof, the fire preventing reliability rate of the utility model relates to 1, the consumption reducing rate of the utility model is above or equal to 99.9%, the storage area of the utility model is increased by 10%, and the utility model has no clamping and sinking accidents.
Description
The utility model belongs to the oil storage tank firebreak device, particularly be oil storage tank inner floating roof firebreak device.
The fire protection of the oil storage tank of widely applying is to set up fire fighting system in the tank field at present, and probe is installed on oil tank top, and the back probe starting of catching fire in jar is passed to the foaming station with signal, and a large amount of foams are ejected in the jar by carrier pipe, extinguish the blaze.
" carrying the oil storage tank inner floating roof of fast fire-extinguishing apparatus " is that the hyperbaric oxygen bottle that is full of inert gas that links to each other with conduit is housed in the plastic float of floating plate periphery, and after periphery caught fire, the starting probe was emitted inert gas, extinguishes the blaze.Also have a kind of smog automatic fire extinguishing technology that is applicable to diesel oil, crude oil and heavy-oil reservoir oil tank (its diameter should less than 16m) in addition, after catching fire in jar, the probe starting, smoke generator is emitted a large amount of fire-retardant smog, is full of in the jar, and fire is extinguished.More than three kinds all belong to the passive type extinguishing device, after promptly oil tank catches fire, main rely on the fire extinguishing of probe starting fire services installations, and probe is in case malfunctioning, very harmful.Concentrate the fire fighting system investment big, system complex, maintenance cost height.
Goal of the invention of the present utility model is: in covered floating roof tank, design a kind of active firebreak device, this device can make oil tank oil storage under anaerobic condition also can prevent that oil gas evaporation is excessive, isolates with kindling material, realizes fire prevention thus.
Goal of the invention of the present utility model is achieved in that a kind of oil storage tank inner floating roof firebreak device of design, mainly contain tank body 14, floating plate 3, firebreak device is concentric with tank body by two at least, the folding elastic body 6 that diameter is different, 8 and annular floating plate link together and form with the floating top of the annular of pasta free lifting, floating top and tank body, and be full of inert gas between the pasta, outlet valve 1 is equipped with on tank body top, near folding elastic body 6 upper ends of tank body 14 and the beam 2 at oil tank top, 4 connect, cover plate 9 is equipped with in folding elastic body 8 upper ends at the tank body center, fixedly connected with interior ring with the outer shroud of annular floating plate respectively in two folding elastic body lower ends, be provided with stroke positioner 5 between roof beam and annular floating plate, the outer rim of annular floating plate, the two ends of axis are provided with anti-rotation block 11, anti-rotary column 15 therefrom passes, and its upper end is fixed with roof beam, and lower end and tank body are fixed.
Folding elastic body is folding elastic bellows, and sealant tape 7 all is equipped with in it and oil tank roof beam 2,4, cover plate 9, annular floating plate 3 junctions.
Stroke positioner 5 is made up of lower lift ring 52 on the upper lift ring 51 on the tank deck central cross beam 4 and the annular floating plate correspondence position and the stroke positioning rope 53 that is connected upper and lower suspension ring.
The utility model has the advantages that:
1. because oil storage tank inner floating roof firebreak device and oil storage tank are assembled into the totally-enclosed system, the oil storage and the external world are isolated fully, and be full of inert gas between floating top and tank body, the pasta, so can realize oil tank oil storage under anaerobic condition.
2. folding elastic body and annular floating plate link together with the pasta free lifting, can prevent that like this oil gas evaporation is excessive, have also completely cut off the chance that oil product contacts with kindling material.
Above-mentioned two characteristics of this device have been blocked the condition of oil storage burning, and oil storage can not be burnt, and have reached active fireproof purpose.
3. because tank skin is not opened pore, comparing storage volumes with general covered floating roof tank increases by 10%, and does not have heavy card accident.
