Description
Technical field
The present invention relates to a kind of vacuum insulation vessel palladium oxide absorber.
Background technology
Normal temperature adsorbent equipment used in the high vacuum multiple layer heat insulation low-temperature (low temperature) vessel of existing manufacture production uses palladium oxide
Wrapping is fixed on the structure design of outer container inwall, and the adsorbent equipment of this structure design mainly has the disadvantage that：
1st, palladium oxide adsorbent equipment is mainly made up of filter paper, filter screen, stainless steel horizontal stripe, the palladium oxide that stainless steel horizontal stripe will bandage
Outer container inwall is fixed on, stainless steel horizontal stripe welds with outer container.For low temperature tank car during adverse circumstances situation, this fixes dress
The danger to come off is equipped with, causes adsorbent adsorption capacity to lose.
2nd, this device must install before inner pressurd vessel and outer container set courage, so cause palladium oxide in absorption vacuum interlayer
Before interior gas, moisture, gas in air are first adsorbed, is completed when low-temperature (low temperature) vessel manufactures, the adsorption capacity of palladium oxide
It is very poor.
The content of the invention
Its purpose of the invention, which is that, provides a kind of vacuum insulation vessel palladium oxide absorber, solves low temperature tank car and exists
During adverse circumstances situation, this fixing device has the danger to come off, cause adsorbent adsorption capacity lose the problem of, have knot
Structure is simple, it is easily manufactured, be easily installed, recoverable the characteristics of.
Adopt the technical scheme that to achieve the above object, a kind of vacuum insulation vessel palladium oxide absorber, including
The explosion-proof seat being arranged on storage tank shell, the explosion-proof seat upper end are provided with lid
Plate, is provided with packing ring between cover plate and explosion-proof seat, the cover plate lower surface is provided with groove, filter paper bag is provided with groove, filters
Paper bag outer layer covers have stainless steel cloth, and the groove lower end is provided with sieve plate, and the sieve plate is fixed on cover plate lower surface through screw
On.
Beneficial effect
The present invention has advantages below compared with prior art.
(1) compare and be fixed palladium oxide with two flat bar cross welding, this structural stability is stronger, preferably ensures
The absorption property of palladium oxide；
(2) compare and encase palladium oxide with filter paper and be put into interlayer, this structure provides effective type of feed and economic filling
Amount, preferably ensure that layer vacuum；
(3) compare and be weldingly fixed on the inside of outside head, this structure is easy to dismount, can recycle palladium oxide, cost-effective；
(4) palladium oxide is placed in the perforate on end socket that compares, and this structure can reduce leak source, preferably ensure that layer vacuum；
(5) compare and place palladium oxide before courage is covered, this structure can carry out placing palladium oxide when heating vacuumizes in tank body, avoid
Palladium oxide is too early to be put into mezzanine space and makes moist, and preferably ensure that layer vacuum.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is schematic structural view of the invention.
Embodiment
The present apparatus includes the explosion-proof seat 7 being arranged on storage tank shell 8, as shown in figure 1, the upper end of explosion-proof seat 7 is provided with lid
Plate 1, is provided with packing ring 6 between cover plate 1 and explosion-proof seat 7, the lower surface of cover plate 1 is provided with groove 9, filter paper bag is provided with groove 9
5, filter paper bag outer layer covers have stainless steel cloth 4, and the lower end of groove 9 is provided with sieve plate 3, and the sieve plate 3 is fixed on lid through screw 2
On the lower surface of plate 1.
Palladium oxide of the filter paper bag 5 built with high-temperature activation.
Palladium oxide can add after tank body interlayer dehydrogenation displacement in the present invention, it is understood that the content of hydrogen is very in air
It is low, but carbon steel in vacuum interlayer and stainless steel plate and sheathing paper adsorption more hydrogen, particularly these materials
The hydrogen adsorbed after heating will be discharged largely, and palladium oxide is put in if now, and palladium oxide will adsorb very
More hydrogen, during use so afterwards, its suction hydrogen effect will have a greatly reduced quality.
As shown in figure 1, the installation of palladium oxide is carried out according to the following steps, the first step, appropriate palladium oxide threading filter paper
The filter paper bag of making；Second step, with stainless (steel) wire filter paper bag is wrapped up, the 3rd step, the palladium oxide wrapped is put into lid
In groove on plate lower surface, the 4th step, side pressure upper sieve plate installs housing screw under groove.Treat that nitrogen displacement helium leak test is qualified
Afterwards, it is possible to the cover plate for having installed palladium oxide is attached on explosion-proof seat tank body is carried out to vacuumize operation, due to being done using above-mentioned
Method, in the case where meeting identical suction hydrogen effect, palladium oxide can at least halve placement.
Storage tank recyclable palladium oxide for having filled half when reprocessing for 5 years, the as everybody knows vacuum of high vacuum multilayer low-temperature (low temperature) vessel
Life-span is 5 years, that is to say, that after general 5 years, tank body interlayer will vacuumize again, now with a mistaken ideas many people think that, five
Year after only at will mend take out vacuum can that, actually such effect is very poor, and 5 years vacuum are returned for overview
Herein below should at least be included by repairing：
A. rise again, that is to say, that the temperature of inner pressurd vessel will return to normal temperature during tank body interlayer vacuum-pumping.
B. interlayer nitrogen displacement, that is to say, that nitrogen displacement several times is carried out during interlayer vacuum-pumping, because the past five
Using in interlayer for year leaks into many inert gases（Other non-inert gas leaked into interlayer air are inhaled by molecular sieve
It is attached）, and vavuum pump only by way of nitrogen displacement, sweeps along inert gas to the pumping speed very little of these inert gases
Release,
C. molecular sieve is changed, by the use of 5 years, a part of molecular sieve may fail because absorbing water excessive, and another part may
It is shattered.
D. seal washer is changed, the seal washer time has been grown can aging.
E. palladium oxide is changed, the hydrogen now adsorbed in the material in interlayer is also put almost, oxygen when reapposing
Changing the dosage of palladium can halve again, the palladium oxide of recovery can dry activate after reuse.
