Description

In existing cyclones, the gas containing dust passes through a series of helical guides (if they exist), where, due to centrifugal force, dust particles with a larger specific gravity are thrown to their outer walls and slide along them moving along with the gas . .After leaving the mixture of pressed dust with gas into the expanded part of the dust separator, the pressed dust should fall into a special collection. But since the gas velocity at the exit to the lower part of the cyclone drops sharply, additional vortex gas motions are formed as a result, small dust particles are picked up by these vortex motions and un6c: tc into the pipe together with the gas. This also contributes to this; that the gas velocity in the central tube is usually quite sufficient to keep these particles from settling.:

In the proposed cyclone with helical channels located inside it, in order to separate suspended particles of dust as they are thrown to the outer walls of the guide screw channels, on the outer wall of the cyclone. There are a number of adjustable windows by the closures through which the dust particles, thrown away under the influence of the centrifugal force, along with a part of the gas, are diverted to a funnel in the bottom of the cyclone, where the dust accumulates and the gas with the smallest dust rises up and is sucked again into the helical channels through adjustable baffles to the holes in the inner wall of the cyclone to separate the finer dust.

In FIG. 1 shows a vertical section of a cyclone; FIG. 2 shows it from the top with a relative lid. ,,

The gas containing suspended particles of dust enters through pipe 1 into guide spiral channels 2 of rectangular section, which have passed through E3 through pipe 3 to the outside. The dust particles that have a specific gravity larger than the specific gravity of the gas flow through the spiral channels — under the influence of the rotational force, are rejected to the outer guide walls and leave, together with part of the gas, in special windows equipped with adjustable closures 4 The magnitude of the opening of these windows is regulated by a screw 5. The dust together with a part of the gas is dust

through channels B, it is withdrawn into the lower cone-shaped part of the funnel 7 of the cyclone, where it, due to the insignificant speed of gas in this part, settles, and the gas, together with part of the smallest dust, rises up through the pipe 8, is sucked through special openings 9, adjustable by a shutter and knob 11, and begins again the rotational movement together with the bulk of the gas to be purified. Thus, in a cyclone, the gas is partially recirculated, the magnitude of which can be controlled by the closures of the windows on the outer wall of the cyclone and the openings 9 on the inner wall of it. The top of the cyclone is closed with a lid 12. By reducing or increasing the amount of the recirculating gas, it is possible to regulate the degree of perfection of cleaning, and to start recycling larger or smaller volumes of dusty gas.

The subject matter of the invention.

Claims (2)

1. A cyclone with screw channels located inside it, characterized by using windows with adjustable closures 4 in its outer wall, opening into channels 6 and serving to separate dust from gases and drain this dust to funnel 7. 2. A variation of the cyclone according to claim 1, characterized by the use of openings 9 in its inner wall, equipped with a regulating shutter and used for sucking dusty gas into them, in order to separate fine dust from it. ff
