SU622990A1 - Rotary dust separator - Google Patents

Description

The invention relates to the field of mining and can be used for the wet collection of dust from the air.

A rotary dust collector is known, comprising a housing with inlet and entry tubes for air, an impeller and a liquid sprinkler ll,

The disadvantage of the dust filter is its low efficiency (|) the efficiency of fine dust collection,

Also known is a rotary pyggeot divider, nktysuyu case, impeller, between KoTopbifviw placed air-permeable shell, forming an urethra-shaped channel with the case, and water supply pipe G21.

The object of the present invention is an increase in the efficiency of drinking fine dust.

This goal is achieved by the fact that the blades are filled with an S-shaped Mibf shape and form gaps in the Vontury pipe through each other. Dust separator can

It is equipped with a drop catcher, fixed at the mouth of the spiral channel. This arrangement of the separator provides intensive coagulation of dust particles in the sides of the shell of the dust particles, 1 fluid of liquid and their sedimentation in the drip catcher and in the droplet separator.

FIG. 1 shows a rotary pin & separator, front view} in FIG. 2, the same side view.

The rotary dust separator includes a housing 1 with an inlet 2 and an outlet 3 with nozzles, an impeller 4 mounted on the shaft S, and a water supply nozzle 6. Inside the case there is an air-permeable shell 7 made of curved blades 8

S-shaped, forming channels 9 of variable cross-section. Between the shell and the inner curvilinear the surface of the casing is formed by a cochlear channel 10, in the mouth of which a droplet separator 11 is placed. At the outlet nozzle 3 there is a nozzle 12

for sludge discharge. The water dispenser is made of the nozzles installed on the collector 13.

Rotational department works as follows.

Dusty air with drops of water sprayed by the sprinkler is sucked into the housing 1 through pat5 and 2. Under the action of pentral forces generated by the rotation of the impeller 4, the plume parts and water droplets are dropped to the shell 7 and partially deposited on the vanes 8. The remaining aerosol parts through channels 9 and the cochlear canal Yu, they go to the droplet separator 11, where the separation of the moisture from the air takes place. Purified air is discharged from the dust collector through the inlet pipe 3, and the sludge is discharged through the drain pipe 12,

The use of the proposed chipper allows significantly improving the efficiency of trapping fine aerosol particles and reducing the dust concentration in the working area air.
