Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dangerous liquid storage, in particular to a multi-stage combined protection storage. BACKGROUND

[0002] Liquid storage is often used to store dangerous chemicals, which are toxic, corrosive, explosive, flammable, and other chemicals that are harmful to the human body, facilities, and environment. Dangerous chemicals include flammable liquids, oxidizing liquids, and are widely used in liquid filling stations, industrial liquid storage, and other related places. When the liquid storage is subjected to accidents such as collision and earthquake waves, the liquid storage may leak or explode, causing casualties and economic losses. At present, the liquid storage structure generally adopts ground or underground structure. Although the underground liquid storage structure is safer, its cost is too high, and the maintenance cost of the liquid storage is higher. Therefore, in most areas, the ground liquid storage structure is still chosen.

[0003] Composite structures have been researched and applied at home and abroad since the Second World War because of their light weight and high relative stiffness. They are widely used in aerospace, transportation, and military protection. The composite protection structure of the liquid storage can effectively prevent damage to the shell caused by impact and enhance the overall impact resistance of the liquid storage. The present application designs a new liquid storage structure through the technical route of penetration prevention, leakage prevention, and explosion prevention. Through multi-stage combined protection, the liquid storage leakage and subsequent explosion caused by leakage are effectively prevented. SUMMARY

[0017] (2) The non-metal barrier explosion suppression ball of the present application divides the space into several "small rooms" or "cavities", which can effectively suppress the propagation of flame and make the explosion pressure wave sharply attenuate. At the same time, the high specific surface area of the material can absorb and conduct a large amount of heat energy, destroy the explosion conditions of the combustion medium, thereby reducing the flame burning speed and ensuring the safety and storage of the fuel liquid. In addition, compared with other explosion suppression materials, the non-metal explosion suppression ball accounts for only about 5% of the total volume of the liquid storage, which can reduce the weight of the liquid storage to a certain extent and improve the transportation quality.

[0018] (3) the liquid storage of the present application adopts the design of ladder type, when adding liquid, from the inner sub-cabin body with the highest height at the top, liquid will flow into the inner cabin body at the bottom, after the inner cabin body is filled, liquid will flow into the outer sub-cabin body with the highest height from the third liquid passage at the top of the partition between the inner cabin body and the outer cabin body, after being filled, liquid will flow into the outer sub-cabin body with the next height, and so on until the outer storage is filled, the advantage of this method is that the part of the liquid in each cabin can be ensured to be at most one cabin, and if the storage cabin is filled only in the inner circle cabin, the outer circle cabin is empty, which can act as a protective shell for the inner circle storage cabin, if a sub-cabin leaks due to impact or earthquake, only the liquid storage in one sub-cabin will be affected, which can minimize the loss and the possibility of subsequent hazards, and under the protection of the multi-level joint protection component, the damage of the explosion can be minimized.

[0019] (4) the protective cover is arranged at the top of the cabin body, because the top of the cabin body is an irregular structure, the protective cover is a plane, therefore, a cavity is formed between the inside of the protective cover and the top of the cabin body, the cavity can not only play a role in buffering the fragments entering the inside of the protective cover, but also can place some components such as liquid pumps and other devices, which can maximize the use of space and play a role in protecting the cabin body, and the protective cover adopts a multi-layer design, which further enhances the safety of the top surface of the storage.

DETAILED DESCRIPTION

[0029] The present application aims at the deficiencies of the existing storage technology, and provides a multi-stage combined protection storage, which is specifically implemented by the following technical scheme:

[0030] REFERENCE Figure 1 The multi-stage combined protection storage comprises a storage arranged above the ground, the top of the storage is provided with a liquid inlet, and the bottom of the storage is provided with a liquid outlet, which facilitates the storage of liquid in and out of the storage, and the liquid inlet and the liquid outlet are both provided with valves which can be independently opened and closed.

[0031] REFERENCE Figure 2 , Figure 3 The storage is divided into an inner cabin body 100 and an outer cabin body 200 by a partition plate 310, the top of the inner cabin body 100 is provided with a liquid inlet, the bottom of the inner cabin body 100 is provided with a liquid outlet, the bottom of the outer cabin body 200 is provided with a liquid outlet, the inner cabin body 100 is divided into a plurality of inner sub-cabin bodies by a plurality of horizontally arranged partition plates 310, the partition plate 310 between two adjacent inner sub-cabin bodies is provided with a first liquid passing port 410, liquid is filled into the first inner sub-cabin body 110 from the uppermost end, and then flows into the second inner sub-cabin body 120 below the first inner sub-cabin body 110, and then flows into the third inner sub-cabin body 130, the fourth inner sub-cabin body 140 and the fifth inner sub-cabin body 150 in turn, until the fifth inner sub-cabin body 150 at the lowermost end is filled, then the fourth inner sub-cabin body 140 is filled, and then the filling is performed in turn until the first inner sub-cabin body 110 is filled, which can form a plurality of independent cabins in the inner sub-cabin bodies, and further enhances the protection performance of the storage.

[0032] REFERENCE Figure 2 , Figure 3The inside of the outer cabin body 200 is divided into several outer sub-cabin bodies by several vertically arranged partitions 310, the vertical height of the top surface of the several outer sub-cabin bodies decreases in turn from the highest first outer sub-cabin body 210, the second outer sub-cabin body 220, the third outer sub-cabin body 230, the fourth outer sub-cabin body 240, the fifth outer sub-cabin body 250, the sixth outer sub-cabin body 260, the seventh outer sub-cabin body 270, and the eighth outer sub-cabin body 280 with the lowest vertical height of the top surface, the second liquid passing port 420 is arranged on the partition 310 between adjacent outer sub-cabin bodies, the horizontal position of the second liquid passing port 420 is lower than the upper surface of the lower outer sub-cabin body, the two outer sub-cabin bodies with the largest vertical height difference of the top surface are in a closed state, the third liquid passing port 430 is arranged on the partition 310 between the inner sub-cabin body with the highest vertical height in the inner cabin body 100 and the outer sub-cabin body with the highest vertical height of the top surface, and the vertical height of the third liquid passing port 430 is lower than the upper surface of the outer sub-cabin body. This design can make the liquid storage only flow into the next second outer sub-cabin body 220 when the highest first outer sub-cabin body 210 is in a full storage state when liquid storage is added from the highest first outer sub-cabin body 210. The possibility of explosion of the cabin body is low when the cabin body is in an empty state and a full state, because there is almost no liquid in the cabin body when it is in an empty state, and there is almost no air in the cabin body when it is in a full state. The cabin body is not easy to explode in the two states. The air and volatile substances of the dangerous goods in the cabin body are in the threshold of easy explosion when the cabin body is in a semi-liquid state, and because the inside is closed, the proportion of volatile substances of the dangerous goods in the air is conducive to the generation of explosion, and explosion is most likely to occur at this time. Therefore, the cabin body is divided into several parts in this design, and liquid storage is added in order. When the cabin body of the inner sub-cabin body is being added with liquid storage, the empty cabin body in the outer circle can act as a protective shell, enhancing the anti-impact ability of the storage structure. The structure adopts a split design, and only when the impact occurs on the cabin body in a semi-cabin state, the storage library may have a large-scale liquid leakage or deflagration, explosion. The structure of the design ensures that only one cabin body in all sub-cabin bodies is in a semi-cabin state, and other cabin bodies can only be in an empty cabin or a full cabin state, and are completed by mechanical structure without the need for electric drive and other modes of driving, which further improves the stability and safety of the structure, and maximizes the stability of the storage structure. The valve with an independent switch is arranged on the first liquid passing port 410, the second liquid passing port 420 and the third liquid passing port 430, ensuring the independence of each cabin body.

[0033] Referring to Figure 4 , Figure 5If the storage tank explodes or deflagrates due to various reasons, the explosion suppression balls 500 divide the space into a plurality of "small rooms" or "cavities", which can effectively suppress the spread of flame and sharply attenuate the explosion pressure wave. At the same time, the high specific surface area of the material can absorb and conduct a large amount of heat energy, destroy the explosion conditions of the combustion medium, thereby reducing the flame burning speed and ensuring the safe storage of the stored liquid. In addition, compared with other explosion suppression materials, the non-metal explosion suppression balls 500 account for a small proportion, only about 5% of the total volume of the storage tank, which can reduce the weight of the storage tank to a certain extent. When the cabin is in a full cabin state, the explosion suppression balls 500 float above the liquid material due to the existence of the filter screen 400. The explosion suppression balls 500 are limited in the cabin where they are located, thereby reducing the contact area of the liquid material and air, reducing the proportion of volatile materials in the cabin, and reducing the possibility of explosion of the cabin while increasing the mass of the stored material.

[0034] Referring to Figure 6 The storage tank shell and the partition plate 310 have the same cross-sectional structure, which is a double-layer structure. The inside is provided with a gap, and the gap is filled with a filling fluid 300. The filling fluid 300 is composed of a shear-hardening glue, which is a non-Newtonian fluid. The main component is polysiloxane, which has strong fluidity and impact resistance. Due to the characteristics of the fluid, it can be simply self-repaired after being penetrated, which can effectively prevent further leakage of the internal liquid or maximize the leakage speed of the liquid. The inner surface of the shell and the partition plate 310 at the joint with the filling fluid 300 is also provided with a self-sealing layer. The self-sealing layer can contract and rebound to reduce the penetration area. At the same time, a small amount of leakage of the stored material in the storage tank can to a certain extent play the role of filling the penetration, thereby achieving the effect of self-sealing of the penetration.

[0035] Referring to Figure 3 The bottom of each of the plurality of outer sub-chambers in the outer cabin 200 is provided with a liquid outlet, which can realize simultaneous liquid output and increase the liquid output efficiency to cope with different emergency situations.
