Description

The invention relates to cryogenic technology, more specifically to tanks for the transportation, storage and evaporation of cryogenic products, and can be used in the preparation of gaseous cryogenic products from liquids in chemical engineering, aviation medicine, and the like.

The aim of the invention is to increase the efficiency of the gasifier in the evaporation mode of the cryoproduct and simplify the design.

FIG. 1 shows the device in the storage mode of the product in FIG. 2, the same, in the gasification mode of the product in FIG. 3 shows section A-A in FIG. 1. The device contains an internal vessel 1, a fixed part 2 of the casing, a movable part 3 of the casing, bellows 4, a heat exchanger 5.

The inner vessel 1 is filled with cryogenic products and placed in a casing consisting of a fixed 2 and a movable 3 parts connected with a sylphon 4. The space between the vessel and the casing is evacuated in order to ensure increased thermal insulation between them. A heat exchanger 5 is rigidly attached to the movable part 3 of the casing. In the heat exchanger 5 there are channels 6 to which coolant is supplied and withdrawn. A support platform 7 is rigidly connected to the fixed part 2 of the casing with the help of studs 8 in the center of the support: platform 7 through which the tension stud 9 with a thread, on which the nut 10 is screwed. The tension stud 9 is fixedly and rigidly connected to the movable part 3 of the casing.

The device works as follows.

In the initial state, the vessel 1 is filled with cryogenic liquid, the movable part of the casing 3 is pressed to the supporting platform 7 by means of a tension stud 9 with a nut 10, the space between the vessel 1 and the casing 2, 3 and the bellows 4 is evacuated. The presence of a vacuum between the vessel 1 and the casing 2 3 provides an increased thermal insulation of the vessel with the cryoproduct from the environment and minimal evaporation loss of the cryoproduct, and therefore the optimum storage conditions for the cryoproduct. To transfer the device to the cryoproduct gasification mode

screwing the nut 10 off the tension 9, as a result of which the pin 9 provides free running for the amount of screwing the nut 10 under it. Under the action of atmospheric pressure, the movable part of the casing 3 together with the pin 9 moves to the vessel 1. The sleeve 4 is shortened by the stroke of the stud 9, ensuring the tightness of the space between the vessel 1 and the casing 2, 3. Supporting platform. 7 is kept stationary with the help of a pin 8. The screwing of the nut 10 is performed until the movable part of the casing 3 has not been installed in the corresponding position on the vessel 1. At the entrance of the heat exchanger 5 from a foreign source, the coolant is supplied to the channel 6. When this heat is transferred from the heat exchanger 5 to the movable part 3 of the casing, the wall of the vessel 1 and the cryoproduct.

The cryoproduct boils and ises is proportional to the amount of heat applied, after which it is removed from the vessel to consumers.

To transfer the device to the cryoproduct storage mode, the heat carrier supply is stopped and the nut 10 is tightened. In this case, the tension stud 9 moves from the vessel and moves the moving part of the casing 3 and the heat exchanger 5 tightly connected with it. The bellows 4 provides the casing 3 and the tightness between parts 2 and 3 of the housing. The nut 10 is threaded up to the stop of the movable part of the casing and the heat exchanger into the support platform 7. As a result, a vacuumized space is formed between vessel 1 and casing 2, 3, which provides the necessary thermal insulation around vessel 1 and minimal evaporation cryogenic losses.

The application of the invention will ensure maximum efficiency of the gasifier, simplify its maintenance during operation, as well as store a liquid cryogenic product with minimal evaporation losses.
