Description

The invention relates to the purification of gases from dust and gas components and can be used in chemical refining, metallurgical and other areas of the industry where high-performance purification of gases is required.

The aim of the invention is to increase the efficiency of dust collection.

FIG. 1 shows the proposed cross cutter with a tapered swirl, FIG. 2 - cylindrical twist; in FIG. 3, the blade B as a curved Gshastina of conical ia of FIG. 4 - rectangular shape.

The isolator comprises a housing I, a nozzle 2 of the input raaaj verT I) a chalical cylindrical nozzle 3 of the gas outlet. The lower end of the nozzle 3 is located in the housing 1, on the cone of which the blade zakryvat is mounted (; or 4 gas flow) The spinner 4 is partially immersed in the liquid. The blades 5 twist are made in the form of curved plates of a conical and rectangular forg-sh .. The blades 5 have ejector headers 6, the blades 5 are installed tangentially along the gauge to meet the gas flow with a curved arc and in such a way that there is a passage through the blades D. of the passageway and the gas flow closures. bone and drain pipe 9,

Pszheulo.vitel works in an ellied manner.

Dusty gas flow through the gas inlet side 2 enters the body 15 in part for, full,: liquid. Large fractions. 1P-1 dust layer for an inertial effect score is deposited on the surface of the liquid, and the inadequate 1 in the fine fraction together with the gas flow enters the scoop twist of the cone of the conical shape.

In the inter-blade section through passage with a ratio of sides O, 6 - O, -99, with a high gas velocity of more than 15 m / s, a stable discharge zone is formed, and

the rise of the fluid along the height of the blade 5 along the slit 6 and the greater the gas velocity, the higher the rise of the fluid. Due to the velocity head from the slit 6, the liquid is ejected into the interscapular section and is crushed by the gas stream into droplets. Due to this,; -yr processing of the filled hectare is intensive. behind the liquid droplets and trapping the liquid. Due to the tangential supply in the swirler, centrifugal forces arise that throw the liquid droplet and trapped dust onto the inner surface of the outlet nozzle 3, the drops get into the expansion chamber and run into the root 1 through the nozzle 9 Purified gases from liquid droplets and pshi are emitted into the atmosphere. The solid fraction is precipitated in the bunker and periodically withdrawn from the body by an airlift. The total area of the twist slots is 052-1.8 square of the living section of the outlet pipe and depends on the gas velocity in the passage slot 7. The greater the gas velocity in | 7; the lower the ratio. The optimal dependence of the length of the blade 057-2-2O on the diameter depends on the degree of its immersion in the liquid and the gas velocity in the flow section. The thinner the dust in the dispersion composition, the higher the gas velocity in the flow section of the spinner and the degree of indentation of the spinner in the liquid and vice versa. The proposed dust collector device makes it possible to increase the effectiveness of dust removal by improving the dispersion of the liquid by the gas stream.

The aspect ratio of the blades affects the efficiency of dust collection. When the gas velocity in the passage is 1xl x 30 m / s at various ratios of the sides, the dust collection efficiency of quartz dust is: at 0.7 - 9955%. 0.8 - 99s3%. 0.9 - 99.0%, 0.99 - 92.0%. In addition, for quartz dust with a different ratio of the areas of the slit passageways and the gas outlet nozzle, the dust removal efficiency is 1.8–74.0%, 0.45–99, 8%, respectively.
