Description
Technical field：
The utility model is related to a kind of ethanol storage tank for pressure transmission line, belongs to fluid chemical warehousing and transportation facilities technology neck
Domain.
Background technology：
Ethanol is inflammable, has excitant.Its steam can form explosive mixture with air, meet naked light, high heat energy and cause combustion
Decrepitate is fried.There is chemical reaction with oxidising agent or cause burning.Its steam is heavier than air, and can be diffused into quite in lower
Where remote, meet burning things which may cause a fire disaster and can catch fire and strile-back, ethanol belongs to Class A liquid, its steam pressure ＜ 0.1MPa at 15 DEG C, so
Belong to B-grade in the first class's class I liquid I.Generally using floating roof or the internal floating roof tank of metal buoyancy module formula, ethanol storage tank zone includes for existing ethanol storage
Basin, ethanol pipeline, valve, the ethanol coupled with storage tank enter tank valve, and output valve, jack works valve shift ethanol valve,
Pipe flange, oil filling riser swivel joint, peep hole, spiracle.Wherein, in place of the ethanol valve of storage tank bottom is key, once let out
Leakage degree of danger is very big.Other leakage points are all discontinuous form leakage points, and leakage is typically all started from seepage, meet fire and are also
The burning of a small range.Basin is made up of welding, and weld seam or steel, may be because of the reasons such as burn into is aging due to using for many years
And making basin ftracture, such ethanol seepage should be found in time, even if catching fire serious consequence of will not also lead to.Natural force can be made
Overflow, cause fire into making basin rupture a large amount of ethanol in moment.When occurring for Accident prevention at present, thermal-flame barbecue environment
Under ethanol basin because in tank, ethanol is overheated the secondary disaster for causing superpressure in tank, rupture caused that gasifies rapidly, should take
Storage tank outer wall around Water spray cooling, reduces temperature in tank.Meanwhile, should be taken into account under accident condition in pressure relief device design aspect
The actuation time of pressure relief device, it is to avoid actuation time is too late because superpressure causes storage tank to rupture；When pressure release amount is determined, should be taken into account
Destroying infection to vapor liquid equilibrium in tank.During for preventing Pool fire from occurring, cause the expansion of disaster because of the expansion of pool area, should
The radius of embankment and height under accident condition is designed according to tank volume.Design tank field and the buildings such as surrounding office, house
Thing apart from when, while except fire-proof and explosion-proof pitch requirements are met, it is also contemplated that the explosion wave according to tank field reserve estimate
Or various destructions, radius of vulnerability size caused by fire heat radiation institute, to reduce burst accident to personnel outside tank field, building
Injury, destruction.But these precautionary measures still can not determine the leakage of ethanol as early as possible, and flameproof effect is not good enough.
Utility model content：
The purpose of this utility model is to provide a kind of ethanol storage tank for pressure transmission line for above-mentioned problem,
For the fire that ethanol leakage causes can be avoided early, flameproof effect is good.
Above-mentioned purpose is realized by following technical scheme：
For the ethanol storage tank of pressure transmission line, including double layers of tank body, described double layers of tank body is by the inner canister for being placed in inside
Body and the outer tank body composition for being placed in inner canister external body, have cavity layer between described interior tank body and described outer tank body, described
Interior tank body connection feed pipe and discharge pipe, described feed pipe and described discharge pipe extend respectively into described
The outside of outer tank body, inlet valve are arranged on feed pipe and are located in described cavity layer, and baiting valve is arranged on described putting
On pipe material and in described cavity layer, inert gas circulating tank is connected to described sky by inert gas conveyance conduit
In cavity layer, in described outer tank body, position corresponding with described inlet valve and described baiting valve is respectively arranged with sealed door.
The described ethanol storage tank for pressure transmission line, the conduction for having ground connection in described outer tank body by electrical connection
Body.
The described ethanol storage tank for pressure transmission line, is provided with alcohol concentration sensor inside described cavity layer.
The described ethanol storage tank for pressure transmission line, has in described outer tank body and installs the convex of described sealed door
Rise, described sealed door is arranged in the projection of described outer tank body by clamping hoop type connection and is sealed by sealing strip.
The described ethanol storage tank for pressure transmission line, is provided with valve on described inert gas conveyance conduit.
The described ethanol storage tank for pressure transmission line, is provided with breather valve on described interior tank body.
Beneficial effect：
The utility model passes through to arrange one layer of tank body again in the outside of ethanol storage tank, and in the interlayer between two-layer tank body
Connection inert gas circulating tank conveying inert gas, even has a small amount of ethanol leakage, due to being in inert gas environment,
Burning will not also be caused or exploded, flameproof effect is good.
