The invention relates to the cleaning

dusty gases behind; by centrifugal forces, in particular to cyclones, and

, can be used, for example, in the industry of building materials in the purification of gases produced in cement, as well as in branches of the national economy.

The aim of the invention is to increase the gas cleaning efficiency and decrease the hydraulic resistance of the cyclone.

The drawing shows a cyclone, longitudinal section.

The cyclone contains a housing 1 with Cilin. 2 and conical 3 parts, upper inlet4 and lower outlet 5 nozzles, hopper 6. The housing contains hollow coaxially truncated cones 7 and 8 in succession, decreasing in the downward direction. Installed with large bases upwards. The cyclone is equipped with a diffuser 9, a pipeline 10 with a flow regulator 11 and an annular manifold 12 installed in the upper part of the bunker and connected with it evenly spaced around the perimeter of the bunker 13. The pipeline 10 inlet section is connected to the collector, and the outlet section 14 is connected to the inlet a nozzle where an ejector is formed, suction gas from the bunker, Diffu, the bore is installed at the inlet to the outlet

an ejector sucking gas from the hopper, a diffuser installed at the inlet to the outlet. The conical elements of the device are installed with the possibility of axial movement and have (in the preferred version) the same angle of inclination to the cyclone axis. The movement is carried out through the levers 15 connected to the mechanism 16. The relay 17 serves to control the pressure difference in the bunker and the case. which controls the flow controller 11 and the mechanism 16 through the system 18 of the actuator mechanisms.

The conical elements of the device are installed with the possibility of axial movement and have (in the preferred execution) the same angle of inclination to the axis of the cyclone, Move-; This is accomplished through levers 15 connected to the mechanism 16 for moving them.

The cyclone operates as follows. The dust-laden gas through pipe 4 enters the body and twists in it. As it is thrown, it is thrown to the periphery and discharged through the annular slots through the cones into the bunker. Part of the gas that enters the bunker with the drink withdraws from through the manifold into the inlet. This part of the gas presses the trapped dust to the inside surface.

the conical part of the cyclone body, cones and facilitates transportation of the fluff into the bunker, prevents the accumulation of dust at the ring gaps, prevents the turbulence of the gas flow in the lower part of the cyclone in front of the diffuser,

Purified gas enters the diffuser and then through the pipe 5 enters the consumer. The presence of a diffuser

at the outlet nozzle ensures smooth entry of the cleaned gases into the outlet nozzle, prevents their turbulization, increases the efficiency of gas purification.

To control the cleaning process, the cyclone can be equipped with a cone movement control system.

The regulator 11 must be opened so that the vacuum in the bunker is higher than in the cyclone body. If the vacuum in the bunker is equal to or lower than in the cyclone body, the air from the bunker is sucked through the annular slots, picks up the captured gas and together with the cleaned gas takes it to the outlet. Gas purification efficiency and cyclone performance decrease. In order to avoid this, the relay 17 is operated, the signal is fed to the system t8 of the actuators, which gives a command to open the regulator 11. The flow cross-section of the pipeline 10 is increased, a large amount of air passing through the annular slots is sucked out of the bunker. The return of trapped drums stops, the efficiency of the cleaning process increases.

When the established vacuum level is reached in the bunker, the relay is activated, the system 18 stops working.

If the volume of dust-laden gases entering the inlet tangential nozzle 4 decreases and the concentration of fluff in it decreases, the filling of the annular slots with the caught liquor will also decrease, while the amount of the inhaled circulating gas through the circular arches will increase,

A portion of the captured fluid along with the circulating gas is directed through from version 13 again into the inlet tangential nozzle. The vacuum in the cyclone body falls. Decreases

with filter performance. In this case, the relay 19, installed on the cyclone body, is triggered, the actuators are triggered by the command of the system 18 and lower the cones and output nozzles through the levers 15. The width of the annular slots is reduced. If the vacuum in the cyclone body reaches the set level, the relay 19 is triggered, the actuators are stopped. If the dust and purge volume of the teMbix gas is more than halved, the moving cones are lowered down and the annular gap closes. The length of the conical part (size) of the cyclone increases; cc, the path of movement of the piston relative to the body increases, the cleaning efficiency increases.
