Description

The utility model relates to the field of creating gas storages, mainly helium, at gas processing and helium plants.

The closest technical solution to the proposed one is the storage of gaseous helium, which includes containers for storing helium connected to a technological system for supplying and selecting helium (see RU 105398 U1, F17C 5/00 (2006.01), B65G 5/00 (2006.01), publ. 06/10/2011). In this case, the containers are metal pressure vessels stacked in rows and interconnected.

The disadvantages of the known technical solutions are:

- a significant number of vessels and fittings for the construction of a gas storage facility of large gas consumption (several million nm ^{3 of} gas) and, accordingly, the complexity of the vessel strapping between each other and with gas injection and extraction systems;

- increased gas losses through the elements of the tank strapping;

- the high cost of vessels, their strapping, control systems and, accordingly, high operating costs for their repair, maintenance and spare parts.

These shortcomings lead to an increase in the cost and time of construction of the storage, to increase operating costs and losses of helium. In addition, the creation and operation of this type of storage requires a large, several-hectare-sized plot of land and appropriate maintenance and repair personnel.

The technical result that the claimed utility model is aimed at is to increase the reliability of a large gas-intensive gaseous helium storage facility by simplifying its design, as well as reducing helium losses, shortening the time and costs of its creation and operation.

The technical result of the utility model is achieved due to the fact that in the storage of gaseous helium, which includes containers for storing helium connected to the technological system for supplying and selecting helium, the tanks are made in the form of at least two pipelines connected at the ends to distribution gas pipelines with a technological supply system and selection of helium on which shut-off and control devices are installed, with each pipeline made of high pressure pipes welded together, inner and / or outer the surface and welded joints of which are equipped with a protective composite material, and the shutoff and control valves are equipped with sealing elements.

The drawing shows a schematic diagram of the storage of gaseous helium.

The gaseous helium storage contains containers for storing gaseous helium in the form of pipelines 1 and 2 connected at the ends to distribution gas pipelines 3 and 4 by a technological system for supplying and selecting helium. The technological system for supplying and selecting helium consists of gas distribution pipelines 3 and 4, as well as gas pipelines for supplying and sampling helium 11 and 12. On the distribution gas pipelines 3 and 4, shut-off and control devices are installed, for example, shut-off valves 5 and three-way valves 6, 7 and 8 .

Instead of three-way valves, valve or spool type switchgear can be used.

Pipelines 1 and 2 are made of high pressure pipes 9 welded together, the inner and / or outer surface and welded joints 10 of which are coated with a protective composite material, and the shut-off and control valves 5-8 are equipped with sealing elements.

Pipelines 1 and 2 can be made straight, as shown in the drawing, as well as circular or combined shapes (not shown in the drawing).

As high pressure pipes, in particular, pipes having a diameter of from 1000 mm to 1420 mm and withstanding a pressure of more than 55 MPa can be used.

As a protective composite material can be used: polyvinyl dichloride, polyamide or polyethylene terephthalate-lavsan.

The described circuit diagram works as follows.

Helium gas through a gas pipeline 11 through a three-way valve 6 is sent through a distribution gas pipeline 3 to pipelines 1 and / or 2. In the operation of the storage facility, the following operating modes can be:

I mode

gas injection into pipeline 1, gas extraction from pipeline 2;

II mode

gas injection into pipeline 2, gas extraction from pipeline 1;

III mode

gas injection simultaneously into pipelines 1 and 2, and simultaneous gas extraction from pipelines 1 and 2.

The implementation of these modes of operation of the storage is carried out by appropriate switching of the three-way valves 6, 7 and 8, as well as opening and closing the shut-off valves 5. Gaseous helium is supplied to the consumer through a gas distribution pipe 4 and a helium extraction gas pipe 12.

The use of pipelines as containers for storing gaseous helium will reduce the number of gas distribution pipelines with shut-off and control devices, which will reduce the leakage of gaseous helium. In addition, the use of protective composite materials and sealing elements will also reduce the leakage of gaseous helium. The use of containers for storing gaseous helium in the form of pipelines instead of pressure vessels will reduce the time and cost of creating a storage facility for gaseous helium of large gas consumption and its operation.

The proposed utility model provides increased reliability of the storage of gaseous helium.
