The invention relates to the scrubbing of gases from dust and can be used in various fields in the home farm for cleaning ventilation emissions from fine dust, including sticking dust.

The purpose of the invention is to increase the efficiency of dust collection, including sticking.

Fig. 1 shows a wet dust collector; in Fig. 2, node I in Fig. 1j in Fig. 3 is an "embodiment of a wet dust collector with an electric drive} in Fig. 4 and 5 — node I in FIG. 1 (net holder, respectively, when the sets grids touch and when the crank is turned 90),

The device comprises a housing 1, the lower part of which is filled with liquid, the upper partition 2 and the lower part partially immersed in the liquid fixed to it, the partition 3 forming between them a slot channel (impeller), drip catcher 4, inlet pipes 5 and outlet 6 of gas and drain pipe 7. On the partition 3 a set of elastic grids B is strengthened, on the partition 2 there is a grid holder 9 with a set of grids THEN. The grid holder 9 is provided with an actuator 11 (for example, a crank) and is mounted freely in the annular guides 12 of the partition 2 with the possibility of circular movement of the axis 13 of the mount. The diameter of the circle-fixing axis 13 exceeds the distance between the grids 8. The distances between the grids 8 and 10 are the same. The actuator can be driven by an impeller 14 connected to it, located on the inlet nozzle 5 (Fig. 1), or an electric motor 15 (Fig. 3).

The device works as follows.

Dust gas enters through inlet pipe 5 into housing 1 and

rushes into the slotted channel formed by the upper 2 and lower 3 partitions. The gas flow rotates the impeller 14, which sets the actuator 11 and, accordingly, the grid holder 9, which moves freely in the guides 12. The pulsating and poorly mixed gas-liquid flow, falling into the working cavity of the impeller, encounters a row of grids 8 and 10 is crushed by them. The mesh cells are wetted with a liquid, and between the grids a porous gas-liquid mixture is formed (a mixture of liquid and gas bubbles), which

is agitated by movable grids 10, making translational circular motions. Making circular movements in the guides 12 (Figures 2 and 5), a set of elastic grids 10 in the upper and lower

points of their trajectory are in contact with a fixed set of elastic grids 8, both sets of grids bend slightly and slide relative to each other, as a result of which the grids are cleared of dust accumulated on them. The dusty gas noTdk, the passage through the slit channel, initially collides with the surface of the liquid.

dust particles under the action of inertial forces penetrate into the fluid layer and are trapped by it. Further, the passage through the impeller through the porous gas-liquid mixture, the gas is repeatedly in contact with the liquid and is cleaned from the fine fluid. The purified gas passes through the droplet separator 4, where it is freed from droplet moisture and is discharged through the pipe 6, and the dust collected by the liquid is periodically removed through the pipe 7.

Thus, in a wet dust collector in the working cavity of the impeller, large gas bubbles are crushed, a homogeneous, stable gas-liquid mixture is formed, through which the dust-containing gas stream containing fine dust is filtered, which improves the efficiency of dust collection and allows the cleaning device to be used gas from sticking dust.

The placement of sets of grids 8 and 10 with alternation of a fixed grid with a moving grid is necessary to ensure their contact with the purpose of cleaning their surfaces from sticking dust. This contact occurs when the grid holder makes 9 circular motions, and the contact occurs only at the upper and lower points of the trajectory of the grids. Simultaneous contact of the grids of both sets is possible only if the distances between the grids in these sets are equal.

Due to the fact that the radius of the circle described by the grid holder.

a little more distance between the adjacent nets in the impeller cavity (meaning the distance between adjacent nets, i.e., mesh 8 and 10), then when contacting, the elastic grids 8 and 10 bend further. When the net holder moves, they slide (rub) over each other's surface, as a result of which the grids are removed from the dust accumulated on them.
