Description
Technical field
The utility model relates to a kind of atmospheric low-temperature liquid storaging device, is specifically related to a kind of low-temperature liquid storage tank.
Background technique
Liquid storaging device has vacuum tank, spherical tank and liquid storage tank etc., and wherein liquid storage tank has following advantage: 1. cryogenic liquide pressure store is low, and its Security is relatively good; 2. low-temperature storage tank achieves maximization, and it takes up an area few, reduces storage cost; 3. reservoir structure is simple, and construction easily, reduces construction cost.
Common storage medium has liquid oxygen, liquid nitrogen, liquid argon, liquefaction sky hot gas etc.The 400m of current actual motion
3low-temperature liquid storage tank is widely used in deep cooling industry, but it still needs larger improvement in reduction liquid gasification rate, device adiabatic heat-insulation, equipment safety operation etc.
Model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides the low-temperature liquid storage tank device of a kind of insulation, safety.
The technical solution of the utility model is achieved in that the low-temperature liquid storage tank device of a kind of insulation, safety; comprise and be arranged on inside groove on platform and water jacket; pearlife thermal insulation layer is filled with between inside groove and water jacket; shielding gas is filled with between inside groove and water jacket; water jacket is connected with water jacket bleeder and water jacket inhalation valve, inside groove is connected with inside groove safety vent device.
Described inside groove circumference is fixed with anchor band.
The base plate paving of described water jacket is in multi cellular glass brick layer, and the base plate of inside groove is arranged on load distribution plate, and load distribution plate is arranged in multi cellular glass brick layer.
Described inside groove surrounding arranges annular spray equipment.
The utility model be a kind of can the Large Copacity device of storing cryogenic fluids, be vertical double wall construction, between inside groove and water jacket, filling pearlife thermal insulation layer carries out thermal insulation and fills drying nitrogen protection.Inside and outside groove inhalation valve and emergency discharge device are set, guarantee equipment safety operation.The utility model structure is simple, and liquid relative evaporation is low, stable operation, safety.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is water jacket bleeder, water jacket inhalation valve and inside groove safety vent device distribution figure.
Wherein: 1. inside groove, 2. water jacket, 3. pearlife thermal insulation layer, 4. multi cellular glass brick layer, 5. flat ledge, 6. water jacket inhalation valve, 7. water jacket bleeder, 8. inside groove safety vent device, 9. anchor band.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As illustrated in fig. 1 and 2; the low-temperature liquid storage tank device of a kind of insulation, safety; comprise and be arranged on inside groove 1 on platform and water jacket 2; inside groove 1 and water jacket 2 top are provided with flat ledge 5; pearlife thermal insulation layer 3 is filled with between inside groove 1 and water jacket 2; be filled with shielding gas between inside groove 1 and water jacket 2, water jacket 2 be connected with water jacket bleeder 7 and water jacket inhalation valve 6, inside groove 1 is connected with inside groove safety vent device 8.Fill shielding gas time adopt automatic type governor valve control, ensure the interlayer constant pressure between inside groove 1 and water jacket 2.Feed liquor pipeline in the utility model adopts U-shaped collocation structure.
The utility model using process is as follows: before the utility model fills cryogenic liquide, first in pearlife thermal insulation layer 3, is filled with drying nitrogen as shielding gas, makes the pressure that water jacket 2 keeps certain, in order to avoid wet air enters and reduces the thermal insulation property of device.In the normal using process of low temperature storing tank: if a. water jacket 2 blanket gas reduces, can water jacket inhalation valve 6 supplementary pressure be passed through, in order to avoid cause water jacket 2 negative pressure; If b. cryogenic liquid leakage, because water jacket 2 temperature is higher, cryogenic liquide sharply evaporates in the short time, by water jacket bleeder 7 emergency decompression, can avoid the security incident because water jacket superpressure causes; If c. cryogenic liquide evaporation is too fast, inside groove 1 pressure raises, and by the emptying of inside groove safety vent device 8, avoids inside groove superpressure.
Preferably, described inside groove 1 circumference is fixed with anchor band 9, and the base plate paving of described water jacket 2 is in multi cellular glass brick layer 4, and the base plate of inside groove 1 is arranged on load distribution plate, and load distribution plate is arranged in multi cellular glass brick layer 4.Anchor band 9 plays fastening effect, prevents inside groove 1 under lifting force effect, and bottom produces evagination distortion.Inside groove and liquid gravity are evenly distributed in multi cellular glass brick layer 4 by load distribution plate.
Described inside groove 1 surrounding arranges annular spray equipment, can ensure inside groove Homogeneous cooling, avoids local temperature difference stress excessive.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
