Abstract
The utility model discloses an anti-swing tower packing for an offshore floating-type device. The anti-swing tower packing comprises regular-hexagonal packing frames which are respectively composed of six metal flat plates (2), wherein common metal-plate corrugated packings (3) are vertically placed in the regular-hexagonal packing frames, the adjacent packing frames are in surface contact to form packing discs (1), and the metal-plate corrugated packings form regular polygons taking the centres of the packing discs as centres. The metal-plate corrugated packings form regular polygons taking the centres of the packing discs as centres, and the upper packing disc and the lower packing disc rotate by 30-90 degrees. The anti-swing tower packing disclosed by the utility model has the beneficial effects that a wall-flow effect caused by swing is eliminated on the whole; additionally, via the support of the external packing frames, the metal-plate corrugated packing in each packing unit is free from bending deformation due to external force extrusion; and finally, the packing units facilitate standardization, promote industrial application, are accurate in installation, and are convenient to overhaul.
Description
Technical field:
The utility model relates to a kind of offshore floating device anti-rock tower packing.
Background technology:
LNG is as a kind of cleaning, the energy more and more is subject to the favor of every country efficiently, along with going deep into gradually of global natural gas exploration and exploitation, increasing gas field, deep-sea, middle-size and small-size marginal gas field and association gas field are found, but the exploitation of offshore natural gas not only environment is severe, technical difficulty is large, and the construction period is long, risk is larger, be unsuitable for adopting marine fixed platform exploitation, FLNG(floating LNG Technology) purification of collection natural gas, liquefaction, store, loading and unloading and outward transport are integrated, be a kind of novel offshore gas field development technique, its device of realizing is called offshore floating device.
Offshore floating device swims in the sea, be subjected to stormy waves, weather, the impact of the factors such as ocean current, the stability of hull is poorer than fixed platform, easily cause particularly rocking of tower of equipment on board, because packed tower has less tower diameter and whole height than the packing box tower, compare with plate column and to have reduced to rock sag and the shearing force that causes, so the tower of offshore floating device is preferentially selected packed tower, the installation level of conventional filler tower General Requirements packing box or packing support circle is not more than 3%, otherwise will produce wall stream and be difficult to recovery, cause the column efficiency heavy losses, most experiments result thinks, the decrease in efficiency that structured packing is caused by the tower inclination is little than dumped packing, but at present domestic also specially for the research of offshore floating device packed tower with structured packing.
But the structured packing patent of domestic open anti-wall flow mainly comprises three classes: the first kind is to add the anti-wall flow circle, such as CN1125673C and CN2246534Y; Equations of The Second Kind is changing the corrugated plating surface configuration or convincing discharge orifice by patient analysis, such as CN2577947Y, 2447049Y, 201171991Y, 2485033Y, 201239626Y and 201644096U etc.; The 3rd class is the overall structure that changes filler, such as CN201431883Y and CN100431687C, because at sea equipment cycle and the angle of rocking is larger, first, two class fillers are all multiple-layer overlapped and vertically are installed in the tower, therefore under this working condition, can not avoid Radial Flow, industrial major diameter structured packing need piecemeal is put into tower from manhole and is installed, although so the disclosed filler of the 3rd class can be avoided Radial Flow to a certain extent, but this type of filler is designed in aggregates can't cutting apart, be not suitable for large stuffing tower and really industrialization, so rocking so that packed tower can't directly be selected conventional filler of offshore floating device need to make improvements.
The utility model content:
The technical problems to be solved in the utility model provides a kind of offshore floating device anti-rock tower packing, and it has new structure, is applied to eliminate packed tower wall stream effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of offshore floating device anti-rock tower packing, comprise the regular hexagon filler frame that six metal plates (2) consist of, the inner vertical common metal mellapak packing (3) of placing, adjacent described filler frame face contacts with face and is combined into packing box (1), and described metallic plate ripple packing forms the regular polygon centered by described packing box center.Make the regular polygon of described metallic plate ripple packing formation centered by described packing box center, two described packing boxs rotate 30 °～90 ° up and down.
Described six metal plates (2) form regular hexagon filler frame by welding, the thickness of metal plate (2) is 0.2～0.8mm, length is 175～250mm, highly be 100～200mm, described metal plate (2) same position place opens the uniform ￠ 3～￠ of the positive triangle 6 circular pod apertures (4) that play the anti-wall flow effect.
On described each corrugated plate of common metal mellapak packing crest, trough are arranged, each corrugated plate is erect and is placed, ripple direction and vertical direction have an inclination angle, the ripple inclination angle equal and opposite in direction of the inner common metal mellapak packing adjacent corrugations sheet that arranges, opposite direction.
Good effect of the present utility model is: packing box is divided into a plurality of parts, so that gas-liquid two-phase reverse contact in the relatively independent space in each filler unit corrugated plating gap, the drainage effect of pod apertures on the described metal plate, so that the flow direction of the fluid on the filler repeatedly changes during rocking, the Radial Flow time lengthens greatly, having suppressed fluid radially flows in packing box on a large scale, make simultaneously the gas-liquid mixed in the packing box even, and finally eliminated on the whole and rocked " the wall stream effect " that causes, the support of outside described filler frame makes metallic plate ripple packing in each filler unit avoid the external force extruding to occur bending and deformation in addition, adopt at last the easy standardization of this filler unit, be conducive to commercial Application, and install accurately, maintenance is convenient.

Major label description in figure:
1-packing box, 2-metal plate, 3-common metal mellapak packing, 4 pod apertures.
The specific embodiment:
Such as Fig. 1, illustrated in Figure 2, a kind of offshore floating device anti-rock tower packing, it is characterized in that: comprise the regular hexagon filler frame that six metal plates 2 consist of, the inner vertical common metal mellapak packing 3 of placing, adjacent described filler frame face contacts with face and is combined into packing box 1, and described metallic plate ripple packing forms the regular polygon centered by described packing box center.Described six metal plates 2 form regular hexagon filler frame by welding, the thickness of metal plate 2 is 0.2～0.8mm, and length is 175～250mm, highly is 100～200mm, described metal plate 2 same position places open the uniform ￠ 3～￠ of the positive triangle 6 circular pod apertures 4 that play the anti-wall flow effect.On described each corrugated plate of common metal mellapak packing crest, trough are arranged, each corrugated plate is erect and is placed, ripple direction and vertical direction have an inclination angle, the ripple inclination angle equal and opposite in direction of the inner common metal mellapak packing adjacent corrugations sheet that arranges, opposite direction.
