SAFE STORAGE DEVICE FOR LIQUID CARGOES Russian patent published in 2016 - IPC E04H7/06 

FIELD: oil industry.

SUBSTANCE: invention relates to the means for safe storage of liquid cargoes such as oil products. The device for the safe storage of liquid cargoes includes a wall, a bottom, a roof and foam generators. The roof is made with fire-fighting boards, each with an inbuilt foam generator and an inspection hatch with a cover. Foam generators are equipped with the nozzles directed at different angles towards the oil level throughout the height and along the circular length of the tank ensuring overlap of the foam jets over the surface of the stored product. Each spray nozzle comprises a hollow cylindrical body coupled to a spreader. The body consists of a cylindrical part with external thread for connection to the nozzle of the distribution manifold for fluid supply, and internal thread for connection to the spreader by means of a disc with a rigidly bound ring through the circular plate with an Archimedean spiral groove the twist direction of which coincides with the twist direction of fluid flow swirler disposed with a gap relative to the inner cylindrical surface of the body and fixed at its lower part through the circular plate rigidly bound thereto with a lower fairing-headed screw. The swirler is designed as a threaded bushing, with external coarse pitch buttress thread, and the internal thread accommodating the threaded part if the fairing at the top of the swirler, and the cylindrical chamber is designed for fluid supply. A cone-shaped perforated spraying device is connected to the lower screw in axial alignment thereto, to its head with a fairing, the tapered end of the spraying device is directed towards the lower screw fairing.

EFFECT: technical result of the invention is increased reliability of safe storage of liquid cargoes.
