SU765591A1 - Gas holder - Google Patents

Description

one

The invention relates to gas xpaHH.THiiuiM and can be used in systems where it is necessary to contain a gas under constant pressure, for example in helium refrigerated and liquefaction plants.

A gasholder is known, consisting of a bell lowered into an annular gap filled with liquid and formed by the walls of the outer and hermetically sealed cover, the inner vertical coaxial cylinders, and the gas pipeline (1) entering under the bell.

The disadvantage of this gas tank is the possibility of liquid from the annular gap entering the gas compression system.

The purpose of the invention is to prevent liquid from the annular gap in the gas pipeline.

This goal, ds), is achieved by the fact that the lid of the inner cylinder is installed below its upper end and the open end of the gas pipe {) water in the same way that the volume of the cavity formed by the lid and upper

part of internal qi, 11indra, is equal to or greater than the volume of fluid in the annular gap.

It is advisable to connect this cavity with the noMouibio pipeline with a valve with an annular gap.

The drawing shows prsdlo. gasholder, longitudinal section.

The gas-holder contains an annular gap 1 formed by the walls of the outer cylinder 2 and the inner cylinder 4 is hermetically sealed with a lid 3. A bell is trimmed into the annular gap with liquid 5. The lid 3

10 of the inner cylinder 4 is installed below its upper end. The volume of space above the cover formed by it and the walls of the inner cylinder is equal to or greater than the volume of liquid in the annular gap. Pipeline

15 6 is welded into the lid of the inner cylinder and brought to the level of its upper end or slightly higher. The space above the cover of the inner cylinder and the gap between the walls of the inner and outer cylinders are connected by pipe 7 to the valve 8.

When pumping gas from the compressor through pipe 6, the bell 5 is lowered until it reaches the lowest position, as shown in the drawing. In case of continuation

Claims (2)

Claim 1. A gas holder containing a bell placed in an annular gap filled with liquid and formed by the walls of the outer and hermetically sealed with the lid of the inner cylinders, and a gas pipe, open end placed under the cap, characterized in that, in order to prevent liquid from the annular gap in the gas the pipeline, the cap of the inner cylinder is installed below its upper end and the open end of the gas pipeline, while the volume of the cavity formed by the cap and the upper part of the inner cylinder is equal to and and more fluid volume in the annulus. 2. Gas holder by π. 1, characterized in that it is provided with a pipeline with a valve connecting the cavity above the cover of the inner cylinder and the annular gap.
