Abstract
The utility model discloses a dry adsorption plant for a deep cold container, and belongs to a container for placing or storing compressed, liquefied or solidified gas, and especially discloses a part of the container. The dry adsorption plant for the deep cold container is characterized in that the dry adsorption plant is fixed on the wall of an inner container by a columnar adsorption chamber shell of which one end is provided with an end socket and the other end is provided with a plugging plate, the end socket one is positioned in the inner container, and the plugging plate end is positioned in an interlayer space arranged between the inner container and an outer shell; and the shell is internally provided with a molecular sieve, the plugging plate is provided with a nitrogen introducing pipe passing through the outer shell and is provided with a gas exchange port, and a sealing plate is covered on the gas exchange port. The dry adsorption plant disclosed by the utility model has the beneficial effects that one part of an adsorption chamber of the dry adsorption plant is positioned in the inner container, the problems that the distance of the interlayer is small and the adsorption chamber cannot be installed are solved; meanwhile, the adsorption chamber is directly contacted with medium of the inner container, so that the adsorption effect of the molecular sieve is better when the temperature is lower; and an opening for installing the adsorption chamber can be used as a process manhole in a manufacturing process.
Description
Technical field
The utility model belongs to splendid attire or stores the component of the gas container, particularly container of 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 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 arranged in interlayer between inner bag and 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.
The model utility content
Need the large deficiency in space between inner-outer tube in order to solve existing adsorbent equipment installation, the purpose of this utility model 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 between inner-outer tube, the space dwindles greatly, is applicable to the deep cooling container that between inner-outer tube, mezzanine space is little and uses.
The technical solution of the utility model 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 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 housing, the nitrogen blanketing valve that passes shell is housed on closure plate, closure plate is provided with gas exchange mouth, is covered with sealing plate on 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: use simultaneously nitrogen blanketing valve that adsorption chamber is vacuumized when the mezzanine space between inner bag and shell is vacuumized after the deep cooling container assembling, and allow degree of vacuum in adsorption chamber higher than the degree of vacuum of mezzanine space, sealing plate is covered on gas exchange mouth, after laminated vacuum reaches specified value and can keep certain hour, be filled with nitrogen by nitrogen blanketing valve in adsorption chamber, when nitrogen pressure during 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 mezzanine space, make mezzanine space keep for a long time vacuum state.
The beneficial effects of the utility model are that the recessed welding of this adsorbent equipment perforate on inner bag is completed, 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, while is direct and inner bag medium contact due to adsorption chamber, temperature is lower, and the adsorption effect of molecular sieve is better.The perforate of adsorption chamber use is installed serves as the use of technique manhole in manufacture process, namely avoided the repetition perforate of container to increase leakage hidden danger, the cleaning of convenient inside again.
