Description

I The invention relates to devices for the purification of gases from suspended particles and liquid droplets, and may find application in various industries.

The purpose of the invention is to provide effective separation with increased g | liquid loading. : FIG. 1 shows a centrifugal separator; in fig. 2 — node I in FIG. one; in fig. 3 - separator with partitions in the form of a conical spiral

The separator contains a housing 1 with ha

The supply 2 and the exhaust gas 3 tubes mounted along the axis of the cone 1 are a conical swirler 4, the patches 5 of which are divided into one located over another section -20 by means of partitions 6, an annular groove 7. for collecting fluid from the drain pipe 8 The partitions are made in the form of grooves 9 open into the vortex cavity, connected by 25 tubes 10 to a drainage pipe 8. Trenches 9 are cross-sectional and have a streamlined shape. Regions 6 can be made in the form

helix 11. Under the swirl 4 is installed sprayer 12

G1 BONE.

The number of sections in the swirler is determined depending on the performance of the separator and its dimensions.

The lateral surface of each section is developed by blades 5 installed with the formation of tangential slots. The width of the gaps between the blades is constant for all sections, which ensures a uniform distribution of the gas scatters across the height of the swirler

The separator operates as follows.

The gas flows through the tube 2 into the housing 1, where the washing liquid is injected through the raspberry 12. The gas picks up the liquid droplets and, in the form of a gas-liquid mixture, flows through the slots formed by tangentially located shovels-5 into the conical swirler 4.

The gas-liquid flow inside the ridge, whom the swirler 4 twists and the form of the rotating flow goes to the output section of the swirl 41. Under the action of centrifugal LL, the fluid particles are pressed to

blades 5 forming a conical surface, and in the form of an expanding conical helix also rise. Due to the fact that the partition 6 between the sections is made in the form of a groove 9, the rotating film of liquid rising from the lower section enters the groove and then is discharged into the drainage pipeline 8,

The gas stream unloaded from a part of the liquid from the lower section enters the zone above the located section, where, mixing with the gas-liquid flow, spun when passing tangential slots between the blades 5 of this section, it participates in the formation of a single rotating flow, and so before leaving the swirler. The fluid, separated in the last section of the swirler, is separated from the purified gas stream and discharged through the annular pocket 7. Thus, the liquid from the lower sections of the swirler does not enter the top, but is removed as sedimentation occurs in each of the overlying sections in the chute 9 The streamlined shape of the grooves in cross section reduces the hydraulic resistance of the swirler, and the implementation of the partition walls 6 in the form of a conical helix contributes to a more rapid drainage of the liquid that has entered the groove 9 to the drainage pipeline 8,

Thanks to the proposed implementation, effective separation is achieved by increasing more than twice the permissible load on the liquid.

Formula of the invention

1. A centrifugal separator comprising a housing with a gas supply and a gas exhaust pipe, a conical swirler installed along the housing axis, the blades of which are divided into one above the other section by means of partitions, an annular fluid collection pocket with a drainage pipe located above one another, different the fact that, in order to ensure effective separation under increased fluid loading, the partitions are formed as swirlers open into the cavity, connected by nozzles with drainage pipeline.

due to the fact that the chute is in shape.
