The invention relates to a cryogenic technique, specifically to tanks for the storage and transportation of cryogenic liquids under conditions of forced oscillations (vibrations, rolling, etc.).

The aim of the invention is to increase the efficiency of storage and dispensing of a cryogenic liquid under conditions of forced vibrations.

FIG. 1 shows a reservoir; general view; FIG. 2 is a section A-A in FIG. 1, in FIG. 3 - through hole of the floating cover.

The tank contains an inner vessel 1 with thermal insulation 2, a vacuum case 3, a floating cover 4. With vertical grooves 5 located on its side wall, guides 6, vertically located on the inner side wall of the vessel 1 and inserted into grooves 5 the heads 4 The lid 4 is provided with vertical plates 7 attached to its lower part, and is provided with additional through holes 8 and entrance cavities 9 distributed from below along its surface.

The tank works as follows. .

When the inner vessel 1 is filled with liquid, the cap 4 emerges and is located on the liquid mirror. With any change in the level of the liquid, the cap 4 moves up or down along the guides 6 of the vessel 1. With the forced oscillations of the tank, the cap 4 dampens drop drops and using plates 7 eliminates the rotational movement of the fluid mass. The resulting pairs of cryo-liquids are collected in the cavity 9 and discharged into the upper part of the vessel 1 through the openings 8. The dynamic loads of the oscillating and rotating fluid are extinguished by the crutch 4 and partially transferred through the guides 6 to the inner vessel 1.

Under the conditions of forced vibrations, the use of the proposed tank allows economical storage of cryo-liquid, reduces dynamic loads on its structural elements, and increases cryo-liquid by means of pressurization of the tank without additional gas consumption, as compared with usual conditions.
