Description
Technical field
The utility model belongs to cryogenic liquide pressure and stores the field.
Background technique
At present, cryogenic liquide is stored employing spheric holder as ethene equitemperature not too low (40 ℃~-70 ℃), and cryogenic liquid tank more, cryogenic liquid tank particularly-100 ℃, have only the columnar shell of cylinder-shaped coat at present, load cold insulation material such as pearlife at the annular space place of two cylindrical shells or vacuumize.For the then primary and secondary jar forms that adopt of large storage tank more, promptly by the experimental process jar after manufactory makes, transport to the scene and with outer jar of " female jar " assembling, cold insulation materials such as pearlife are then filled in the gap.But primary and secondary jar form thinks that the quantity of son jar can not be above 7 owing to be subjected to a kind of influence of idea.It is economical that this idea is meant that the artificer of primary and secondary jar thinks that female jar has only circle to be only, and therefore to surpass 7 female jar will be uneconomic to son jar quantity.In addition, also to pay the traffic expense that transfinites with expensive made, particularly large-scale secondary and primary jar, invest very big because cryogenic liquid tank is many usually.So being forced to change into normal pressure under a lot of situations stores.But pressure is stored and can be avoided using the low temperature Under Water Pumps, and a lot of situation downforce are stored tangible advantage.Other outlet is to change gas phase into to store, and this obviously is uneconomic.Spherical container is the form of saving material in the basin most, and common gas or liquid are stored and extensively adopted spherical container, but up to the present, does not also have the practical application of-100 ℃ and following low temperature spherical tank.Reason can reduce following several: 1. cryogenic liquide requires with made such as stainless steels, and stainless steel is made spherical tank certain degree of difficulty; 2. low-temperature (low temperature) vessel needs special cold insulation structure; 3. pass by to large-scale low-temperature liquid storage tank demand few.
To be solved in the utility model is to obtain most economical large-scale low-temperature liquid bunkerage with good device structure scheme and reliable cold insulation mode.
The model utility content
The utility model relates to the device of cryogenic liquide storage and cold insulation.This device is for complete cryogenic liquide storage system, comprised loading and unloading and the layout of safety installations, equipment and pipeline and the required corollary equipment of technological process, main equipment, operation control system, cryogenic liquide.
The utility model is applicable to that the pressure storage of cryogenic liquide comprises: liquid methane (LNG), liquid oxygen (O
2), liquid nitrogen (N
2) wait and the temperature range of storing is other liquid of-100 ℃ to-196 ℃.The feature of this device is that the basin body is a spherical container, and material is stainless steel or other low temperature resistant made, and its filling weight can reach 95% of total measurement (volume).Two sections column support types are adopted in the supporting of spheric holder, and its effect had both reduced the cold that imports ground into and also adapted to simultaneously and install and the temperature difference when storing liquid, reduced the stress that the temperature difference causes.Two sections pillar designs fully take into account effect of heat insulation and the free in-plane displancement of bearing.
The cold insulation structure of this device comprises following three kinds of forms, applicable to different occasions, and can be according to the size of storage capacity, the different choice of storing liquid.
First kind of form is cylindrical shape or polygonal shell.Be applicable to large storage tank.The outer space of shell inner cavity and spheroid is full of cold insulation material and nitrogen such as pearlife.And make nitrogen remain micro positive pressure to prevent to suck moisture.Pearlife requires bone dry state and vacuum packaging.Adopt corresponding measure to prevent that pearlife from sucking moisture during filling.The urceolus internal diameter is selected bigger approximately 2 meters than spherical shell diameter.Its purpose one is the thickness that increases cold insulation thing (pearlife), the 2nd, when the spheroid pressure testing, can advance people's inspection and operation, and a spherical interior jar of employing Air Pressure Test For Strength guarantees that all weld seams of spherical shell do not have leak.All polish in order to reduce the radiative heat transfer outer surface of spheroid.Spheroid does not adopt flange to connect except that manhole and all external interfaces all cause urceolus.Manhole then adopts the welding gasket form.All external interfaces all adopt effectively cold insulation measures such as vacuum cold insulation.Instrument (temperature, liquid level, pressure) all adopts two covers to be provided with.Total interface is located at the top of spherical shell as far as possible.Sheathing material also can adopt other material except that adopting box hat, add as reinforced concrete, Lightweight Steel Construction and go along with sb. to guard him etc.
Second kind of form is double-layer spherical shell.Endosphere is made (stainless steel, copper, aluminium, nickel steel etc.) shell with low temperature material and is then used carbon steel.The chuck space vacuumizes (high vacuum).Common this form is suitable for middle-size and small-size basin, and therefore, spherical tank " endosphere " adopts the skirt supporting, and skirt is a two section type for the same reason.Vacuumize that radiative heat transfer is main under the condition, therefore in outer surface of ball to polish and add thermoinsulation material and twine with aluminium foil.
The third is the on-the-spot large-scale double-deck ball container of making, and interlayer vacuumizes and load pearlife.Be applicable to large and medium-sized basin, especially cold insulation required height, the basin that must vacuumize between chuck.The requirement of endosphere and first kind of form are identical.The manufacturing of ectosphere then must be finished also in the endosphere manufacturing and carry out after the passed examination.Because vacuumize, shell also belongs to a class pressurized container, but the welding of spheroid can only be a welding by one side, and designing requirement adds backing plate or single face welding and double face shaping technology.The welding inspection ultrasound.In case of necessity also can special intermediate plate mode weld to intersect and carry out with X-ray examination.For preventing that solar irradiation from conducting heat, ectosphere can add sun-proof material.
The utility model has also comprised endosphere combination sphere structure, and this combination is diversified.It can be medium and small, also can form the large storage tank of primary and secondary jar form, because female jar can be selected other shape for use, so the quantity of son jar is not subjected to 7 restriction.Can make the minimum investment of middle-size and small-size refrigerated storage tank cost with this combination spheroid.
The utility model can make cryogenic liquide (100 ℃~-196 ℃) store a day amount of vaporization be reduced to<below 0.15%, manufacture cost descends significantly simultaneously.
