Abstract
The utility model discloses a sway-proof protection device of a top-loading liquidometer. The Sway-proof protection device of the top-loading liquidometer comprises a sway-proof tube (5). The top of the sway-proof tube (5) is welded with a container (4). The sway-proof tube (5) is provided with a lower section open pore (7), a bottom open pore (8) and an upper section round hole oppositely formed (6). The diameter of the lower section open pore (7) and the bottom open pore (8) is 6 mm. The diameter of the upper section round hole oppositely formed (6) is 15mm. The Sway-proof protection device of the top-loading liquidometer has the advantages that time for medium which is outside the sway-proof tube entering the sway-proof tube is delayed through changing the size and number of the open pores, due to the fact that the sway-proof tube is set. Therefore, influence of sway is delayed, influence of the sway factors on measurement accuracy of the liquidometer is reduced, measurement accuracy of the liquidometer is greatly improved and normal running of a complete set of production equipment is guaranteed.
Description
Technical field:
The utility model relates to offshore floating device liquid level emasuring device technical field, is specially a kind of roof-mounted liquid level gauge anti-rock protective device.
Background technology:
LNG more and more is subject to the favor of every country as a kind of cleaning, the efficient energy.Along with going deep into gradually of global gas prospecting and exploitation, increasing gas field, deep-sea, middle-size and small-size marginal gas field and association gas field are found.But not only environment is severe in the exploitation of offshore natural gas, technical difficulty is large, and the construction period is long, risk is larger, is unsuitable for adopting marine fixed platform exploitation.FLNG(floating LNG Technology) integrating purification, liquefaction, storage, loading and unloading and the outward transport of rock gas, is a kind of novel offshore gas field development technique.
Roof-mounted liquid level gauge is widely used in the level gauging of floating liquefied natural gas (LNG) production device.Roof-mounted liquid level gauge commonly used mainly contains: guide wave radar liquid level gauge, magnetostriction liquidometer, RF Liquid Level Instrument, interior float level meter etc.Because floating liquefied natural gas (LNG) production device swims in the sea, be subjected to the impact of the factors such as stormy waves, weather, ocean current, the stability of hull is poorer than stationary platform, easily causes rocking of equipment on board, thereby so that container inner medium rock.Usually used liquid level gauge measuring sensor is not with protective device; liquid level in the container is periodically rocked along with rocking of hull; the level value that causes liquid level gauge to be measured can not reflect the real level value of internal tank in real time, has affected the operation of a whole set of process units normal running and security and stability.
At present domestic also do not have specially for the research of floating liquefied natural gas (LNG) production device with roof-mounted liquid level gauge protective device.
The utility model content:
The technical problems to be solved in the utility model provides a kind of roof-mounted liquid level gauge anti-rock protective device, guarantees the accurate measurement of floating type device liquid level.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of roof-mounted liquid level gauge anti-rock protective device comprises the anti-shake pipe (5) that top and container (4) weld, and anti-shake pipe (5) has hypomere perforate (7), bottom opening (8) and epimere and splits circular hole (6); The diameter of described hypomere perforate (7), bottom opening (8) is 6mm, and it is 15mm that epimere is split circular hole (6) diameter.
Bore size and the open amount of described bottom opening (8) and hypomere perforate (7) satisfy following relation:
Wherein H is the maximum relative height that causes the device interior slosh, and T is the slosh cycle of offshore floating device, and the anti-shake pipe is θ=T/2 to delaying the time that liquid sloshing is worked in the equipment, and anti-shake pipe opening diameter is d
0, the diameter of anti-shake pipe is D.
Anti-shake pipe bottom or lower end perforate require:
1, circular hole should make anti-shake intraluminal fluid position and the outer liquid level of sleeve pipe be consistent;
2, in slosh cycle, circular hole farthest delays liquid enters or flows out the anti-shake pipe;
3, in the liquid level gauge course of work, circular hole is immersed in the medium all the time;
4, circular hole is opened in anti-shake pipe bottom as far as possible, when bottom space is inadequate, is chosen in anti-shake pipe lateral opening hole.
Follow rule from the bottom to top during lateral opening hole, be followed successively by from the bottom to top first lap perforate, the second circle perforate ...The adjacent turn perforate is spaced apart and is not more than 10mm.
Good effect of the present utility model is: owing to be provided with the anti-shake pipe, can postpone the outer medium of anti-shake pipe and enter time in the anti-shake pipe by changing bore size and the number of openings, therefore the effect that postpones has been played in the impact of rocking, reduced the factor of rocking to the impact of liquid level gauge measuring accuracy, greatly improve the measuring accuracy of liquid level gauge, guaranteed the normal operation of a whole set of process units.
Description of drawings:
Fig. 1 is roof-mounted liquid level gauge anti-shake tubular construction synoptic diagram.
Fig. 2 is anti-shake tubular construction vertical view.
Among the figure: 1 measuring sensor, 2 media, 3 measuring sensor conduits, 4 horizontal vessels, 5 anti-shake pipes, 6 epimeres are split circular hole, 7 hypomere perforates, 8 bottom opening, 9 maximums and are rocked height H, 10 anti-shake pipe lower end opening diameter d
0, 11 anti-shake pipe diameter D, 12 liquid level gauges.
Embodiment:
Anticipate as shown in Figure 1 and Figure 2, a kind of roof-mounted liquid level gauge anti-rock protective device comprises the anti-shake pipe 5 that top and container 4 weld, and anti-shake pipe 5 has hypomere perforate 7, bottom opening 8 and epimere and splits circular hole 6; The diameter of described hypomere perforate 7, bottom opening 8 is 6mm, and it is 15mm that epimere is split circular hole 6 diameters.
Described bottom opening 8 and hypomere perforate 7 bore size and open amount satisfy following relation:
Wherein H is the maximum relative height that causes the device interior slosh, and T is the slosh cycle of offshore floating device, and the anti-shake pipe is θ=T/2 to delaying the time that liquid sloshing is worked in the equipment, and anti-shake pipe opening diameter is d
0, the diameter of anti-shake pipe is D.
Liquid level in the anti-shake pipe is connected with liquid level in the container by bottom and hypomere perforate.Not perforate on the anti-shake pipe between minimum liquid level and the highest liquid level.Medium can only enter in the anti-shake pipe by anti-shake pipe bottom and hypomere perforate.By changing bottom and hypomere bore size and quantity, greatly improved rocking of anti-shake intraluminal fluid position, improved the precision of measuring, guaranteed the normal operation of a whole set of process units.
The utility model not only is confined to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a utility model or akin technical scheme, all within its protection domain.
