Abstract
The utility model discloses a dry filler adsorption chamber belonging to devices that keep a cryogenic container interlayer vacuum. The absorption chamber is characterized in that molecular sieves is installed inside an adsorption chamber housing formed by a bottom plate and a sealing head, a connecting pipe connected with an gas suction port and a nitrogen inlet is arranged at one end of the adsorption chamber, the connecting pipe is connected with a buffer chamber, a filter plate is mounted at the other end of the buffer chamber, and a gas exchange port equipped with a damage-prone seal plate is formed at the other end of the housing. When in use, the adsorption chamber is fixed in a cryogenic container interlayer, a certain amount of molecular sieves are sealed in the adsorption chamber, the adsorption chamber is vacuumized until the vacuum degree inside the adsorption chamber is higher than that in the interlayer so that the adsorption chamber is in a pressurized state and pressure causes the seal plate (e.g. 0.05 mm copper plate) to be attached to a pore plate to achieve the function of sealing, after the vacuum degree in the interlayer measures up to the prescribed value and remains at the level for a period of time, nitrogen is infused into the adsorption chamber through the nitrogen inlet until the pressure in the adsorption chamber is higher than that in the interlayer to the degree that nitrogen can break through the seal plate, and the adsorption chamber is enabled to be communicated with the interlayer. Therefore, the adsorption chamber achieves the function of absorbing moisture from the inside of the interlayer, with the vacuum degree in the interlayer retained for a long term.
Description
Technical field
The utility model belongs to the device that keeps the deep cooling container laminated vacuum.
Background technique
The interlayer of deep cooling container such as LNG Liquefied natural gas accumulating jar need be in vacuum state, reach high vacuum for realizing that vacuum adopts to bleed for a long time, but filler in the interlayer and equipment making material still can give out a spot of gas or moisture, in order to keep interlayer to keep vacuum for a long time, usually use molecular sieve as sorbing material.
The model utility content
The purpose of this utility model provides a kind of adsorption chamber of dry filler, and a small amount of gas that occurs in the interlayer of the LNG Liquefied natural gas accumulating jar after the adsorption chamber of this a kind of dry filler is applicable to and bleeds and the absorption of moisture are to keep the condition of high vacuum degree of tank body interlayer.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of adsorption chamber of dry filler, it is characterized in that: in the adsorption chamber housing of forming by base plate and end socket molecular sieve is housed, the one end is for connecting the adapter of bleeding with the inflated with nitrogen mouth, adapter is connecting buffer cell, the buffer cell the other end is equipped with filter plate, the other end of housing for be equipped with the destructible sealing plate the gas exchange mouth.
Described gas exchange mouth is enclosed within the gland in the connection block by the connection block that is fixed on the end socket, and porous supporting plate and destructible shut are equipped with in the gland bottom, and the exchange mouth is equipped with by the fixing glass fibre cloth guard shield of retainer ring.
The sheet copper that described destructible sealing plate is S=0.05mm is made.
The disclosed adsorption chamber of the utility model is fixed at the deep cooling container interlayer, a certain amount of molecular sieve of the indoor sealing of adsorption chamber, adsorption chamber vacuumizes, degree of vacuum will be higher than degree of vacuum in the interlayer, make adsorption chamber be in pressured state, sealing plate (copper coin of 0.05mm) pressurized is attached to playing seal action on the orifice plate.After treating that laminated vacuum reaches specified value and can keep certain hour, charge into mouth by nitrogen and charge into nitrogen, pressure is higher than the interlayer internal pressure, and nitrogen breaks through sealing plate makes adsorption chamber and interlayer UNICOM, play the effect of moisture in the absorption interlayer, guarantee that degree of vacuum can keep for a long time in the interlayer.
