Abstract
The invention provides a cryogenic insulation mobile storage tank safety system. The invention aims at solving safety problems of existing cryogenic insulation mobile storage tanks in multiple working conditions. The system provided by the invention comprises a storage tank used for storing and transporting cryogenic liquefied gas; an inner vessel safety device used for discharging gas during storing, transporting and filling working conditions; an interlayer rupture disc used for performing pressure relieving protection when interlayer pressure increases; and a safe discharging device used for safely discharging small amount of gas during the transportation and storage processes. With the cryogenic insulation mobile storage tank safety system provided by the invention, gas discharged by the safety device passes a flame arrester and is directly discharged. During the filling working state, discharged hydrogen is connected with a system hydrogen row, and is subjected to a safe combustion treatment in the system. A welded-type reversed-arch membrane sheet is adopted as the interlayer rupture disc, and flange connection is adopted, such that characteristics of convenient installation and high reliability are provided. With the system provided by the invention, storage tank working pressure can be ensured to be steady.
Description
Technical field
The present invention relates to a kind of cryogenic insulation mobile storage tank safety system, belong to storage tank safety technical field.
Background technique
Safety system is refrigerated storage tank important composition, generally for basin actual conditions, adopts the combining form of safety valve, rupture disk.For the basin of multi-operating mode, the working pressure difference of its different operating mode is comparatively large, adopts existing security setting, by the phenomenon making basin there is long-time superpressure, is both unfavorable for that the quality of cryogenic media keeps, is also unfavorable for storage tank safety.
Summary of the invention
The object of the invention is, in order to solve existing cryogenic insulation mobile storage tank safety system function singleness, well to adapt to the problem of multi-operating mode, and then a kind of cryogenic insulation mobile storage tank safety system is provided.
The object of the invention is to be achieved through the following technical solutions:
The present invention includes: basin, for storage and transfer of cryogenic liquid gas; Inner container safety installations, for discharging hydrogen under storage, transport and filling operating mode; Interlayer rupture disk, for carrying out decompression protection when interlayer pressure raises; Hydric safe tapping equipment is hydric safe discharge a small amount of in transport and storage process.
Hydrogen is inflammable and explosive danger medium, the present invention is directed to different operating mode inner container and have employed two groups of safety installationss, and devise hydric safe tapping equipment, guarantee storage tank safety.Under storage and comfortable property, the hydrogen discharged by the safety installations that one group of pressure is lower, by directly discharging after flame trap.During filling operating mode, close the stop valve between two cover safety installationss, carried out the discharge under accident condition by the safety installations that another group pressure is higher, the discharge hydrogen under nominal situation is arranged with system hydrogen and is connected, and the system of entering carries out safe combustion process.Interlayer rupture disk adopts the anti-dome-shaped diaphragm of welding type, and Flange joint, have easy for installation, that reliability is high feature, above-mentioned system can ensure that basin working pressure is steady.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cryogenic insulation mobile storage tank safety system that embodiment of the present invention provides;
Fig. 2 is the structural representation of the hydric safe tapping equipment that embodiment of the present invention provides.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: the present embodiment is implemented under premised on technical solution of the present invention, gives detailed mode of execution, but protection scope of the present invention is not limited to following embodiment.
As depicted in figs. 1 and 2, a kind of cryogenic insulation mobile storage tank safety system involved by the present embodiment, comprising: basin 1, for storage and transfer of cryogenic liquid gas; Inner container safety installations 2, for discharging hydrogen under storage, transport and filling operating mode; Interlayer rupture disk 3, for carrying out decompression protection when interlayer pressure raises; Hydric safe tapping equipment 4 is hydric safe discharge a small amount of in transport and storage process.
Described inner container safety installations 2 comprises the first safety valve S01, the second safety valve S02, the 3rd safety valve S03, the 4th safety valve S04, the first rupture disk H01 and the second rupture disk H02, one group in parallel of first safety valve S01 and the second safety valve S02, mainly use in storage and comfortable property, cracking pressure is 0.3MPa; 3rd safety valve S03, the first rupture disk H01 and the 4th safety valve S04, the second rupture disk H02 are in parallel as another group again after connecting respectively, and mainly use in filling operating mode, wherein opening pressure of safety valve is 0.63MPa, and bursting pressure of bursting sheet is 0.68MPa.Storage and transport time, open the first stop valve V35, due to the first safety valve S01 and the second safety valve S02 cracking pressure low, therefore when system overpressure, this group safety valve works.During normal filling, working pressure brings up to 0.6MPa, for preventing the first safety valve S01 and the second safety valve S02 superpressure take-off from affecting basin work, close the first stop valve V35, the 3rd safety valve S03, the 4th safety valve S04 and the first rupture disk H01 and the second rupture disk H02 work.Storage and comfortable property under, safety installations discharge hydrogen, by directly discharging after flame trap.During filling operating mode, the hydrogen discharge under accident condition is discharged by the safety installations that pressure is higher, and under nominal situation, extensive discharge hydrogen is arranged with system hydrogen and is connected, and the system of entering carries out safe combustion process.
Interlayer rupture disk 3: when interlayer pressure raises, protected by interlayer rupture disk 3 pressure release.Interlayer rupture disk adopts the anti-dome-shaped diaphragm of welding type, and Flange joint, has easy for installation, that reliability is high feature.
Hydric safe tapping equipment 4: for convenience of hydric safe discharge a small amount of in transport and storage process, it comprises discharge pipe 4-1, two group of branches discharge pipe 4-2, branch discharge pipe 4-2 is evenly arranged floss hole discharge bend 4-3 down, discharge for eminence, both ensured that hydrogen discharged under permissible velocity, and can prevent again rainwater and other foreign material from entering discharge pipe.
Inner container safety installations 2 is connected by the second stop valve with hydric safe tapping equipment 4.
The above; be only the present invention's preferably embodiment; these embodiments are all based on the different implementations under general idea of the present invention; and protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
