Description

(54) DUST COLLECTOR

one

The invention relates to mountain spilliness and can be used to reduce the dustiness of the air during the combines breed and other faces with the formation of a large amount of fine dust as an integral part of the dust collecting unit with wet air cleaning.

A mine shaft dust collector is known, comprising a housing, a swirler, and a sprinkler 1

The disadvantage of such a dust collector is the very low efficiency of air purification from fine dust fractions.

Closest to the proposed technical entity is a Microdist.n dust collector, comprising a housing, a fixed vortex swirler, a screen and a sprinkler 2,

The disadvantage of this dust collector is the low efficiency of trapping fine particles, caused by a decrease in the amount of suction air due to clogging of the mesh with dust and insufficient sedimentation and wetting of fine dust.

The purpose of the invention is to increase the efficiency of trapping finely divided plush by intensive precipitation and wetting in the air stream.

The goal is achieved by the fact that the paddle swirler is installed with the possibility of free rotation and is equipped with a mesh fixed on its outer surface and an additional irrigator, which is installed with a swirl radius between the longitudinal axis of the dust collector and the inner surface of the housing. And the grid can be installed

5 both on one side of the surface of the swirler, and on both sides.

FIG. 1 shows an axle catcher, a longitudinal section; Fig. 2 shows a variant of the blade vortex body, a longitudinal section; in fig. 3 the same, another option.

SUBSTANCE: dust collector comprises body 1, blade swirler 2 and sprinkler 3. Blade swirl 2 is made

5 with the possibility of free rotation under the action of the air flow and consists of the sleeve 4 and the guide vanes 5 installed on it and rests on the shaft 6 with the support 7. The blade swirler 2 rests on the shaft 6

and the bearings located in the support 7, Podshpiniki can be located not only in the support 7, but also in the sleeve 4. At the same time, the blade swirl 2 rests on the shaft b, fixed stationary in the support 7.

In order to increase air purification from fine dust fractions, the vane swirler is provided with a grid 8 fixed on it, made, for example, of metal wire, rotatably with the vane scribe and overlapping the cross section of the dust collector body 1. The grid 8 can be installed before the guide vanes 5 (Fig. 1), behind the Guide vanes 5, Fig 2, and simultaneously on both sides of the guide vanes 5 (Fig. 3 Before the grid 8 of the blade 2 radiator between The longitudinal axis 9 of the dust collector and the inner surface 10 of the case. A 1 have an additional irrigator 11 of the radial continuous water plume.

The additional sprinkler 11 consists of a water supply tube with one or more nozzles, the number of which is selected depending on the diameter of the housing 1 so that it creates a continuous solid water torch across the entire radius between the longitudinal axis 9 and the inner surface 10 of the housing 1. Sprinkler 3 is installed in housing 1 or in an air inlet pipe installed before the dust collector.

In operation of the "dust removal unit", the dusty air under the pressure of the fan enters the dust collector, is irrigated with water using the sprinkler 3, as a result of which large fractions of dust are moistened with water and turn into sludge, partially purified air passes through the mesh cells and fine dust settles on the wetted surface of the grid 8. Under the influence of the air flow on the guide vanes 5, the rotation of the swirl blades occurs: device 2 together with the grid 8. Transverse. The intersection of the wire of the rotating network of 8 moving in the longitudinal direction of the air-water flow leads to effective sedimentation and wetting.

dust on the wet surface of the grid 8. During its rotation, the grid 8 passes through a radial continuous water plume, as a result of which the weeping deposited on it constantly occurs and the grid 8 is prevented from clogging. The air passing through the guide vanes 5 acquires Bpaiqal movement. Under the action of centrifugal force from the rotation of the air flow, further separation of dust in the pipeline connected to the outlet of the dust collector occurs. Air 6 ° wetted with dust in the form of sludge is directed to the sludge collector of a dust collecting unit to separate the sludge from the air.

The proposed dust collector can significantly improve the efficiency of air purification from fine dust.
