Abstract
The invention discloses a drying and adsorption device for a cryogenic container, belongs to containers which are used for containing or storing condensed, liquefied, or solidified gas, and in particular to parts of the containers. The drying and adsorption device for the cryogenic container is characterized in that an adsorption chamber shell is fixed on the wall of a liner, an end socket is installed at one end of the adsorption chamber shell and a blocking board is arranged at the other end of the adsorption chamber shell, the end which is provided with the end socket is located inside the liner, the end which is provided with the blocking board is located inside a interlayer space between the liner and a housing, a molecular sieve is installed inside the shell, a nitrogen blanketing tube which is through the housing is arranged on the blocking board, a gas exchange mouth is formed in the blocking board, and a sealing board is covered on the gas exchange mouth. The drying and adsorption device for the cryogenic container has the advantages that one part of an adsorption chamber of drying and adsorption device for the cryogenic container is located inside the liner, the problem that the adsorption chamber can not be installed because the interlayer space is small is resolved, at the same time, the adsorption chamber directly contacts with liner medium, and the lower the temperature is, the better the adsorption effect is. An open pore which is used when the adsorption chamber is installed can be used as a process manhole during the process of manufacturing.
Description
Technical field
The invention belongs to the component of the gas container, particularly container of splendid attire or the storage compression, liquefaction or curing.
Background technique
The interlayer of deep cooling container such as LNG Storage, Transport tank need to be in vacuum state, reach high vacuum for realizing that vacuum adopts to bleed for a long time, but the filler in the interlayer and equipment making material still can give out a small amount of gas or moisture, in order to keep interlayer to keep for a long time vacuum, usually use molecular sieve as sorbing material.Claimant's formerly patent CN201363549 discloses the absorption problem that " a kind of adsorption chamber of dry filler " preferably resolves residual gas in the deep cooling container interlayer, but this adsorption chamber is installed in the interlayer between inner bag and the shell fully, is only applicable to the larger situation of mezzanine space.With the development of Thermo Isolation Technique, the deep cooling container particularly mezzanine space of the equipment such as LNG tank car is more and more less, and former adsorbent equipment can't adapt to.
Summary of the invention
Need the large deficiency in space between the inner-outer tube in order to solve existing adsorbent equipment installation, the purpose of this invention is to provide the dry adsorbent equipment of a kind of deep cooling container.Or else this device changes and takies under the prerequisite of adsorption chamber volume that the space dwindles greatly between the inner-outer tube, is applicable to the deep cooling container that mezzanine space is little between the inner-outer tube and uses.
Technological scheme of the present invention is, the dry adsorbent equipment of a kind of deep cooling container, it is characterized in that: by an end the columnar adsorption chamber housing that the end socket the other end is equipped with closure plate is housed and is fixed on the wall of inner container, wherein end socket one end is positioned at inner bag inside, be equipped with in the mezzanine space of an end between inner bag and shell of closure plate, molecular sieve is housed in the housing, the nitrogen blanketing valve that passes shell is housed on the closure plate, closure plate is provided with gas exchange mouth, is covered with sealing plate on the gas exchange mouth.
Described sealing plate is the copper coin of 0.05mm.
Deep cooling container is with the using method of dry adsorbent equipment, it is characterized in that: when the mezzanine space between inner bag and the shell is vacuumized, use simultaneously nitrogen blanketing valve that adsorption chamber is vacuumized after the deep cooling container assembling, and allow the interior degree of vacuum of adsorption chamber be higher than the degree of vacuum of mezzanine space, sealing plate is covered on the gas exchange mouth, after laminated vacuum reaches specified value and can keep certain hour, in adsorption chamber, be filled with nitrogen by nitrogen blanketing valve, when nitrogen pressure is higher than the interlayer internal pressure, nitrogen breaks through sealing plate makes adsorption chamber and interlayer UNICOM, at this moment seal the suction port of nitrogen blanketing valve, molecular sieve begins to adsorb the residual gas in the mezzanine space, makes mezzanine space keep for a long time vacuum state.
The invention has the beneficial effects as follows that the recessed welding of this adsorbent equipment perforate on inner bag finishes, make an adsorption chamber part be positioned at inner bag inside, solved because of the little problem that adsorption chamber can't be installed of interlayer distance, simultaneously because adsorption chamber is direct and the inner bag medium contact, temperature is lower, and the adsorption effect of molecular sieve is better.The perforate of adsorption chamber use is installed in manufacture process, can serves as the use of technique manhole, namely avoided the repetition perforate of container to increase leakage hidden danger, the again cleaning of convenient inside.
