Embodiment
The embodiment of the present application discloses a kind of liquefied natural gas filling landing stage LNG storage tank, and storage tank integral installation, on the pedestal of wharf boat body, comprises the LNG storage tank be arranged on hull and the ice chest structure carried thereof.Liquefied natural gas (LNG) tank comprises the interior outer container of low temperature resistant steel matter, also comprises the discharge pipe line filling pipeline and use LNG filling LNG, also comprises vapor return line, measurement of correlation liquid level pipeline etc. simultaneously; Contain process pipelines and valve etc. inside all steel structure ice chest, also have inlets and putlets of ventilation simultaneously, once find natural gas leaking, induced draft fan just can drain into safety zone by rock gas.Whole device, as the capital equipment on liquefied natural gas filling landing stage, achieves the hidden danger of LNG storage tank district without natural gas leaking on landing stage.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be described in detail the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, belongs to the scope of protection of the invention.
Shown in ginseng Fig. 1 and Fig. 2, liquefied natural gas filling landing stage LNG storage tank comprises saddle 1, the tank body 2 be supported on saddle, be formed at tank body 2 one end tank body draw pipeline 3, saddle 1 comprises the first saddle and the second saddle that arrange along tank body axially spaced-apart, second saddle is drawn pipeline 3 near tank body 2 and is arranged, first saddle and the second saddle are respectively and circumferentially form 6 strong points 4 between tank body 2, these 6 strong points are symmetrical with tank body 2 both sides, vertically can relative sliding between first saddle 101 and tank body 2, relative fixing between the second saddle with tank body 2.
In this technological scheme, supporting structure is according to the feature of low-temperature (low temperature) vessel, ten two supporting way adopted, have employed between each saddle and tank body within the scope of 90 °, storage tank top and 2 glass reinforced plastic supports are set, four glass reinforced plastic supports are set within the scope of 120 °, storage tank bottom, the load such as be up and down subject on boats and ships according to storage tank affect rational deployment; Slide in the one end simultaneously designed, one end fixing device, solves inner container after chance cold events, the shearing problem suffered by support.The high-quality glass fibre reinforced plastics simultaneously adopted can reduce this key issue of storage tank leaking heat.
Tank body 2 comprises outer container 201 and is positioned at the inner container 202 of outer container, is filled with sandwich layer thermal insulating material 5 between outer container 201 and inner container 202.Bracing ring 6 is circumferentially formed between inner container 202 and outer container 201, bracing ring 6 comprises spaced first bracing ring 601 and the second bracing ring 602, first saddle and the second saddle vertically and is supported in respectively on the first bracing ring 601 and the second bracing ring 602.In first bracing ring 601 and the second bracing ring 602, circumferentially array is provided with multiple angle steel 7 respectively.Interlayer top between outer container 201 and inner container 202 is filled with anti-settling thermal-protective material 8.
In this technological scheme, outer container support zone arranges a circle intercostal angle 7, can strengthen the intensity of support zone; The anti-settling thermal-protective material 8 that interlayer top is arranged, the problem of heat is leaked in local because Action of Gravity Field sedimentation causes top to occur to solve in use sandwich layer thermal insulating material pearlife 5, and anti-settling thermal-protective material 8 is preferably adiabatic continuous.
Swash plate 9 and anti-swirl baffle 10 is provided with in inner container 202.
In this technological scheme, swash plate can effectively prevent the liquid of boats and ships in the process of rocking in storage tank to the impact of left and right sides end socket, reduces impulsive load, avoids end socket to destroy because fatigue produces; Anti-swirl baffle effectively prevents storage tank from filling with in return-air process, and liquid enters and exits in storage tank and produces vortex phenomenon.
Be provided with two in inner container 202 and overlap independently liquid level emasuring device 11.
In this technological scheme, overlap independently liquid level emasuring device by two, the using and the reserved function can be realized, level gauging and security coordinated signals function in tank can be realized again simultaneously.
The both sides of tank body 2 are symmetrically arranged with 2 hangers 12 respectively.
In this technological scheme, the non-standard axial lifting lug of employing, rational deployment, avoids in product hoisting process, the problems such as shackle structure localized stress is excessive.
Tank body is drawn pipeline 3 and is sealed in ice chest parts 13, and these ice chest parts 13 have an intake grill and a suction opeing, and ice chest parts 13 are also provided with combustible gas detector and gas-tight door.
In this technological scheme, all pipelines of drawing in ice chest parts accommodation tank and valve instrument etc., effectively prevent product in use, because valve instrument etc. leaks the potential safety hazard caused.Arrange intake grill, suction opeing simultaneously, be equiped with combustible gas detector, add air-tight door structure at ice chest top, easy access personnel enter and exit ice chest.
Storage tank also comprises flow-off and gas phase mouth 14, and this flow-off and gas phase mouth 14 are formed at the middle part of tank body.
In this technological scheme, inner container comprises inner barrel and interior end socket, adopts the low temperature material of Austenitic Stainless Steel, effectively can store LNG Liquefied natural gas.The process pipelines comprised, integrates and fills, return-air, with liquid, thermometry, overflow, level gauging etc., considers the impact of expanding with heat and contract with cold on pipeline in design process.Wherein flow-off and gas phase mouth are arranged in the middle part of storage tank, avoid the measurement that internal vessel liquid fills because storage tank rocks and produce error, prevent liquid from flowing out to outside from gas phase mouth simultaneously, freeze safety valve and cause potential safety hazard.
It should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or control panel, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ...
