The utility model discloses establish the technology head in the inner tank to filling the molecular sieve in the technology head, so not only doing benefit to molecular sieve performance adsorption, thereby improve adsorption effect, inner tank and the intermediate layer between outer jar have been abdicated to the technology head moreover.
Description
Technical field
The utility model belongs to LNG storage tank field, particularly relates to a kind of technique end socket and molecular sieve mounting structure of LNG storage tank.
Background technique
LNG storage tank is a kind of conventional LNG plant, and it comprises inner and outer tank, and the interlayer between these two tank bodies fills up pearlife thermoinsulation material, to carry out thermal insulation.In order to make thermoinsulation material ensure long-term insulation effect, the interlayer at present between inner and outer tank is equipped with molecular sieve, in order to adsorb the moisture of thermoinsulation material release.Meanwhile, the technique end socket in inner canister, normally flange portion is towards outer tank, is welded in inner canister by technique end socket after workman completes maintenance.
The defect of existing structure is; 1, technique end socket occupies a large amount of mezzanine spaces, and pearlife thermoinsulation material can not be filled in these spaces, will affect insulation effect to a certain extent like this; 2, because molecular sieve is contained in the interlayer between inner and outer tank, and molecular sieve adsorption effect is at low ambient temperatures better, and this setup is just unfavorable for the adsorption effect improving molecular sieve.
Model utility content
Technical problem to be solved in the utility model is the technique end socket and the molecular sieve mounting structure that provide a kind of LNG storage tank, for improving the adsorption effect of molecular sieve, and vacates more mezzanine space for filling heat insulator.
The technical solution of the utility model is as follows: a kind of technique end socket of LNG storage tank and molecular sieve mounting structure, comprise inner canister (1), technique end socket (4) and molecular sieve (5), interlayer wherein between inner canister (1) and outer tank (2) fills up pearlife thermoinsulation material (3), it is characterized in that: described technique end socket (4) is contained in inner canister (1), described molecular sieve (5) is filled with in this technique end socket, and the opening of technique end socket (4) is closed by one piece of orifice plate (6), and have via hole on this orifice plate; Explosion thin slice (8) is clamped between described orifice plate (6) and cover plate (7), this two boards is welded and fixed together, and cover plate (7) is welded and fixed with the internal surface of described inner canister (1) simultaneously, and center hole on cover plate (7) is relative with the aperture position of inner canister (1); Described cover plate (7) has an osculum, a suction tude (9) is fixed with in this osculum, described explosion thin slice (8) is aimed in the outlet side of this suction tude, and the inlet end of suction tude (9) is through after the via hole of described outer tank (2), reaches outside this outer tank.
In the utility model, have adjusted mounting point and the mode of technique end socket (4) and molecular sieve (5), and be arranged in inner canister (1), in suction tude (9), hot nitrogen is injected during use, explosion thin slice (8) breaks through by this hot nitrogen, thus the molecular sieve (5) in technique end socket (4) is communicated with pearlife thermoinsulation material (3) by the center hole of the hole on orifice plate (6) and cover plate (7), thus absorption pearlife thermoinsulation material (3).Further, because molecular sieve (5) is closer to the LNG in inner canister (1), and LNG temperature is well below normal temperature, is so just more conducive to molecular sieve (5) and plays suction-operated, thus improve adsorption effect.
Adopt above technological scheme, technique end socket (4) is located in inner canister (1) by the utility model, and molecular sieve (5) is filled in technique end socket (4), so not only be beneficial to molecular sieve (5) and play suction-operated, thus improve adsorption effect, and technique end socket (4) has abdicated the interlayer between inner canister (1) and outer tank (2), to fill more thermoinsulation material at this interlayer place, thus to improve insulation effect.
As preferably, described suction tude (9) is provided with a plug (10) with the contacting point of outer tank (2).
Beneficial effect: technique end socket is located in inner canister by the utility model, and by molecular sieve filled in technique end socket, so not only be beneficial to molecular sieve and play suction-operated, thus improve adsorption effect, and technique end socket has abdicated the interlayer between inner and outer tank, to fill more thermoinsulation material at this interlayer place, thus to improve insulation effect, kill two birds with one stone.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Fig. 1,2 and 3, a kind of technique end socket of LNG storage tank and molecular sieve mounting structure, formed primarily of inner canister 1, outer tank 2, pearlife thermoinsulation material 3, technique end socket 4, molecular sieve 5, orifice plate 6, cover plate 7, explosion thin slice 8 and suction tude 9.Wherein, the interlayer between inner canister 1 and outer tank 2 fills up pearlife thermoinsulation material 3, and inner canister 1 is for the LNG liquid of splendid attire low temperature.
Technique end socket 4 is cover-shaped structure, and is contained in inner canister 1, is filled with molecular sieve 5 in this technique end socket 4, and the opening of technique end socket 4 is closed by one piece of orifice plate 6, and gathers at this orifice plate 6 and have via hole.Clamp explosion thin slice 8 between orifice plate 6 and cover plate 7, this two boards is welded and fixed together.Cover plate 7 is welded and fixed with the internal surface of inner canister 1 simultaneously, and center hole on cover plate 7 is relative with the aperture position of inner canister 1.Cover plate 7 has an osculum, be fixed with a suction tude 9 in this osculum, explosion thin slice 8 is aimed in the outlet side of this suction tude 9, and the inlet end of suction tude 9 is through after the via hole of outer tank 2, reaches outside this outer tank 2.Further, suction tude 9 is provided with a plug 10 with the contacting point of outer tank 2.
