Description

The invention relates; to the technique of gas purification from vapor-dispersed impurities and can be used in the chemical, petrochemical and other sectors of the industry.

The purpose of the invention is to intensify the processes of condensation and separation and increase operational reliability by reducing the adhesive properties.

The drawing shows schematically the proposed separator.

The separator contains vortex tubes 3 and 4 fixed in tube sheets 1 and 2, equipped with swirlers 5, pipes 6 and 7, respectively, of the cooled stream and purified gas and connected to the receiving chamber 8 and the collecting chamber 9 of separation products. Each vortex tube 3, 4 in front of the swirler 5. is equipped with an ejection device in the form of a cooled stream nozzle 6 and a hemispherical damper 10 installed above it, forming an internal circulation loop. The nozzles 7 of the purified gas are located coaxially with the corresponding vortex tubes. All inner surfaces of the operator are coated with varnish, and the collection chamber 9 is equipped with nozzles 11 for introducing nitrogen, reagents, and solvent.

In the tube sheet 1, at the points where the pipes 3 and 4 are connected to the receiving chamber 8, guide cones 12 are installed.

A fitting 13 is provided for the removal of separation products. The vortex tubes are placed in a common housing 14 for their thermostatting or cooling.

The separator works as follows. The gas containing vapor-dispersed impurities enters the receiving chamber 8, in which guide cones 12 are installed,

eliminating the formation of stagnant zones and the deposition of products, then through the screw channels of the swirler 5 enters the form of a swirling jet into the vortex tubes 3 and 4. In the vortex tubes 3 and 4 the effect of temperature separation is realized, accompanied by processes of condensation and separation of impurities under the action of low temperatures and centrifugal forces . The liquid and solid phase aerosol concentrates on the periphery and is discharged into the collection chamber 9. A cooled stream containing an unseparated fine aerosol phase that forms in the axial zone of the vortex tube enters the cones 12 zone. The source gas from chamber 8 carries away the cooled stream mixes with it and enters through the swirlers 5 into the pipes 3 and 4, where under the action of the centrifugal floor the fine aerosol is separated. Thus, part of the source gas in the form of a cooled stream is in the process of

internal circulation.

The cleaned gas is discharged through pipe 7 from the separator. Separation products are discharged from collection chamber 9 through clamp 13; To clean the collection chamber 9, it is necessary to install nozzles 11 for supplying nitrogen, reagents, and a solvent.
