Description
Technical field
The utility model relates to a kind of high vacuum low-temperature (low temperature) vessel molecular sieve adsorption device, particularly a kind of high vacuum multi-lay winding low-temperature tanker molecular sieve adsorption device.
Background technology
At present, in high vacuum multi-lay winding low-temperature (low temperature) vessel (tank car) design and making, all involve a crucial parts-molecular sieve adsorption device.The effect of its reality is equivalent to a cryogenic absorption formula molecular pump, its action principle is after container charges into cryogenic fluid, its cold cools off the adsorbent of molecular sieve in the molecular sieve adsorption device rapidly, owing in the adsorbent of molecular sieve cooling procedure, can adsorb a large amount of gases, thereby the layer vacuum of low-temperature (low temperature) vessel (tank car) is improved a lot, generally can make layer vacuum improve an order of magnitude usually.So the effect quality of molecular sieve adsorption device is directly connected to the height of low-temperature (low temperature) vessel (tank car) vacuum.The height of vacuum is directly connected to the quality of the static evaporation rate of most important index of low-temperature (low temperature) vessel (tank car) again.Make at low-temperature (low temperature) vessel (tank car) and to finish under the certain situation of back leakage venting rate, the height of the container vacuum the when quality of molecular sieve device has just determined low temperature just is presented as the quality quality of this low-temperature (low temperature) vessel (tank car).
The existing molecular sieve adsorption device of making the high vacuum multi-lay winding low-temperature (low temperature) vessel of producing (tank car) all adopts the central tube parts. design, and the adsorbent equipment of this structural design mainly contains following shortcoming:
1) molecular sieve adsorption device (central tube) mainly is made up of three parts usually, and they are respectively reinforced pipes, bobbin, and the garden plate, three parts all adopt the form of angle welding to connect mutually.Because central tube is in adverse circumstances at work for a long time, (bear the high pressure of solution evaporation in the inner pressurd vessel in the central tube outside, the condition of high vacuum degree of interlayer is born in central tube inside), container (tank car) is wanted the variation significantly of bearing temperature when packing solution and unloading on the other hand, therefore the weld seam of central tube is subjected to very big pulsating stress effect, occur the crack easily, cause container leakage.In case this situation occurs, not only detect and search difficulty, keep in repair more difficult.Because central tube belongs to the container in the container, at all can't repair welding to leak source.Thereby we are considered as the weakest part of quality in the whole low-temperature (low temperature) vessel with central tube usually, and the someone plays and is called the caecum of high vacuum multi-lay winding low-temperature (low temperature) vessel (tank car);
2) ducting capacity is relatively poor, common molecular sieve adsorption device (central tube) internal diameter 130mm, length 2000mm.
About 26 liters of volume.Because the structure of central tube is more elongated, and is far away apart from vacuum chamber during adsorbed gas for the adsorbent of molecular sieve in the bottom, the effect of absorption can be poor, is that ducting capacity is poor to whole adsorbent equipment.
The utility model content
Its purpose of the utility model just is to provide a kind of high vacuum low-temperature (low temperature) vessel molecular sieve adsorption device, thereby solved incidental quality problems on the link the weakest on the inner pressurd vessel, directly eliminated potential biggest quality hidden danger.Have the better characteristics of adsorption effect, and improved the useful load of car load, saved cost, keep in repair conveniently, improved the total quality of low-temperature (low temperature) vessel.
The technical scheme that realizes above-mentioned purpose and take, comprise inner pressurd vessel, outer container, inner pressurd vessel is provided with the technology manhole, outer container is provided with venting, described technology manhole shell ring is provided with shrouding, described shrouding is provided with external screw thread and connects mouth and suction nozzle, is provided with adsorbent of molecular sieve in the cavity between described shrouding and the manhole end socket.
Compared with prior art, the beneficial effects of the utility model are:
1) adsorption effect of this device is better, we know that the moisture content of adsorbent of molecular sieve and ducting capacity play a part very crucial to the molecular sieve adsorption performance, adsorbent of molecular sieve and air are isolated fully, thereby the water content that can make adsorbent of molecular sieve is accomplished extremely low, because this device is near flat, molecule is sieved to the distance of conducting orifice all less than 300mm, so ducting capacity is more a lot of greatly than former central tube device;
2) removed original molecular sieve adsorption device central tube, thereby eliminated quality link the weakest in the former manufacture process, improved the total quality of low-temperature (low temperature) vessel (tank car), reduced welded seam simultaneously, solve incidental quality problems on the link the weakest on the inner pressurd vessel, directly eliminated potential biggest quality hidden danger;
3) remove former central tube parts and make low-temperature (low temperature) vessel (tank car) load volume increase about 26 liters, gross mass descends about 30 kilograms.Thereby reduced manufactory's direct production cost (being about 0.5%), improved the useful load of car load, for the user has saved cost of transportation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure schematic front view.
Fig. 2 be among Fig. 1 A to local enlarged diagram.
The specific embodiment
Embodiment, comprise inner pressurd vessel 1, outer container 2, inner pressurd vessel 1 is provided with technology manhole 4, outer container 2 is provided with venting 3, as shown in Figure 1, described technology manhole 4 shell rings are provided with shrouding 6, and described shrouding 6 is provided with external screw thread and connects mouth 7 and suction nozzle 9, are provided with adsorbent of molecular sieve 5 in the cavity between described shrouding 6 and the manhole end socket 11.
Described external screw thread connects mouth 7 and is provided with screw plug 8, and described suction nozzle 9 bottoms are provided with spherical sieve plate 10.
Described venting 3 is arranged on the outer container 2 terminal end sockets, and is relative with technology manhole 4 positions.
Cavity volume is 20-40 liters between described shrouding 6 and the manhole end socket 11.
This device is to have utilized the technology manhole 4 on the inner pressurd vessel, changes it container containing of adsorbent of molecular sieve into.
Former technology manhole 4 its mainly to act on be to be convenient to whole seam welding in the inner pressurd vessel manufacture process, flaw detection, clear assorted cleaning the and special the setting, the container manufacturing finishes usually, the last soldering and sealing of technology manhole has also just lost its effect.This device is to add shrouding 6 of weldering on former technology manhole 4 shell rings, thereby forms a container that is about 30 liters, and this container all is splendid as needed low temperature environment of molecular sieve adsorption and ducting capacity aspect.
It is to adopt to be threaded that the adsorbent of this device adds loading port, therefore is more prone to when needing to change when adsorbent of molecular sieve loses efficacy with age.
Because the position of former venting 3 moves to afterbody top venting 3 from container top, make tank car venting 3 be difficult for being broken and lose vacuum by foreign matter.
Welding position owing to venting 3 bases has moved on on the terminal end socket from the cylindrical shell center in addition, thereby has significantly reduced welding deformation, makes venting 3 installation qualities obtain highly effective improvement.
