Description

The invention relates to industrial energy and can be used in compressed air power systems and gas pipelines.

The purpose of the invention is to increase the efficiency of gas cleaning from a dropping liquid.

FIG. 1 shows a separator with a single cleaning module, open; in fig. 2 - cleaning module; in fig. 3 - multi-module separator, general view.

The compressed gas separator contains a housing 1 with inlet pipes 2 and a gas outlet 3, a trap 4, an annular separating element 5 located between the disks 6 and 7, and in the disk 7 there is an opening (nozzle) 8, a U-shaped shell 9, studs 10 mounting the disk 6 to the disk 7. The case 1 is located vertically and has forming cylinder 11. If it is necessary to clean large gas flow rates, the supply pipe 2 is connected to the vertical distributor 12, which is muffled from below, with rows of side distributor tubes 13 to which the separators are attached. email items with disks and U-shaped shell.

The separator of compressed gases works as follows.

The compressed gas to be cleaned is in accordance with the patent, the cabin 2 is fed through the opening 8 (nozzle) into the internal cavity of the separating elements 5, where large droplets are deposited on the disk 6 due to its flowing over with a stream of gas flowing from the melt 8 and small droplets in the separating elements 5 Separating elements 5 are made of corrugated mesh strips with opposite inclination of the corrugations in adjacent strips. Small drops are deposited in them and they merge with each other under the action of capillary forces arising in the corners of the cells of the corrugated grids. The drained drops are carried by the flow from the element 5. At the same time, the drops that are carried out from the lower part of the separating element move to the lower part of the body under the force of gravity and fall on the condensate drain 4, from where they are automatically removed. The steam trap 4 is made of a capillary-porous type. The fluid from the housing 1 is removed through it through overpressure and capillary forces.

In order to avoid re-entrainment of droplets by the flow from the upper part of the separating elements 5, installation of a U-shaped shell 9 is provided. Disks with a separating element and U-shaped shell form a cleaning module. The gas velocity in the cross section between the upper part of the discs and the U-shaped shell should be

less than the velocity of the gas in the upper part of the separating element, immersed in the shell. This is achieved by the fact that in the first case the flow area is 1.5-2.0 times larger than the output section of the recessed part of the separating element, therefore, secondary drift of droplets from the U-shaped shell space 9 is excluded. Gas with large drops of liquid carried out from the upper part of the separating elements, changes its direction in the cavity of the U-shaped shell to the opposite and moves down the shell walls. At the same time, large droplets removed from the separating element 5 fall into the lower part of the housing, and from there through the condensate drain 4 are removed from the housing 1. The purified gas changes its direction at the outlet of the shell 9 and enters the outlet pipe 3.

In the case of high costs of the gases being cleaned, the cleaning modules are installed on the distributor 12. At the same time, distributor tubes 13 are attached to the gas distributor, to which the modules are attached. On one pipe-distributor can be mounted from 2 to 16 or more modules. Such an arrangement of the modules allows them to be placed compactly, unifies the separator design — a set of modules provide the necessary gas supply. In addition, mass and weight indicators are reduced.
