Description

I

The invention can be used in ventilation systems and is intended for air purification from dry or wet dust.

A device for cleaning air from dust is known, comprising a housing with inlet and outlet nozzles and a bag filter located inside the housing.

However, such a device is characterized by a high cleaning efficiency; in addition, it is not universal, and it cannot be used for wet cleaning.

In the proposed device for inter-cleaning the outside of the body, there are two coaxial shells, the outer of which is provided with a screw bottom adjacent to the body and guide vanes located on its inner surface, and its upper edge attached to the upper edge of the body. In addition, a sprinkler system is installed in the upper part of the casing and the inner shell, and a protective umbrella is installed above the bag filter, and the inlets are equipped with switching means.

FIG. shows the proposed device for cleaning air from dust in the section; pas figs. 2 is a section along A-A in FIG. .

A dry cyclone 2 with inlet pipe 3 and hose is mounted inside the housing I.

filter 4 with a shaking mechanism 5. In the lower part of housing I, a hopper 6 is mounted for collecting dry dust.

On the main body, above its input

a nozzle 3, a shell 7 is installed with a diameter greater than the body I. The space between the body and the shell 7 is divided by a coaxial shell 8. The internal cavity in its upper part is tightly closed by an annular cover 9. The shell 8 is equipped with a tangential inlet 10, forming a cyclone with an irrigation system 12.

The external cavity between the shells 7 and S forms an annular channel 13 for supplying air from the cyclone to the fan 14. Guiding blades 15 are installed between the shells 7 and 8.

The shell 7 is provided with a screw diy 16, adjacent to the body, forming a cone-shaped bath with a snus nozzle 17 in its

lower part. In the bath one of the famous

methods maintained constant

water.

In place of spawning from irrigated cyclops I

Zigzag guides 18 are mounted to the channel 13 at the level of the water in the bath to create the effect of a hydrodynamic dust collector.

The fan 14 is equipped with an internal perforated non-partition wall 19 and an external one.

solid partition 20, which serves as a continuation of the shell 7. Rehellents form a water intake space 21 with a solid inclined bottom 22 with an annular opening 23 for the flow of water caught from the air.

Bag filter 4 on top of moisture from entering it with a protective umbrella 24.

Inlet pipes 3 and 10, when connected to a new network of supplying dusty air to the unit, are equipped with switching facilities (not shown).

A device for cleaning air from ached works as follows.

When cleaning from dry whine, the dusty air is sucked in by the fan 14 through the inlet pipe 3 into the dry cyclone 2; On the nervous stage of the cleaning in the cyclone 2, the air flows through the second stage of cleaning in the bag filter 4, from where the fan 14 is ejected into the room. The caught dug is poured into the bunker 6, from where it is periodically removed. The bag filter 4 is periodically cleaned of dust using a shaking mechanism 5.

If it is necessary to clean the air from wet dust, the dusty air is sucked in by the fan 14 through the inlet 10 to the cyclone 11, which is equipped with an irrigation system 12 in the upper part. After passing through the wet cleaning in the cyclone 11, the air through channel 13 is directed to the fan 14, while at the point of transition from the cyclone 11 to the channel 13, due to the zigzag guide 18 mounted at the level of the water in the bath, the air takes with it the water that forms the curtains, the passage through which the air undergoes additional cleaning amicheskogo dust separator.

In the duct 13, the air with droplet moisture is twisted by the narabling blades 15. As a result, a part of the drip moisture, and with it the elusive dust particles coarsen and fall out of the air.

From channel 13, the air is sucked in by the fan 14, in which additional droplet separation occurs along with the elusive dust particles as follows: under the action of centrifugal forces, droplets of moisture are thrown by the blades of the fan 14 to the perforated non-city 19, through which they enter the receiving space 21, and overlap the bottom 22 through the annular holes 23 flow through the channel 13 into the bath. At the same time, the moisture separated from the air is discharged towards the air flow, thereby making additional air contact with water.

The cleaned and dried air is blown by the fan 14 into the room in which the unit is installed, and the sludge water (water with trapped dust) from the bath is discharged into the sewer system through the outlet fitting 17.

When cleaning the air in the cyclone 11, the bag filter 4 is protected from moisture by a protective umbrella 24.

Switching the operation of the unit from dry cleaning to wet and vice versa is carried out by a switching device, such as a toggle valve (not shown).
