Description

The invention relates to the mining industry and can be used for the dedusting of various mining and technological processes, in particular for the dedusting of preparatory faces, as well as during downward and upward ventilation of lavas.

The purpose of the invention is to increase the efficiency of cleaning mine air from dust by increasing the degree of turbulence and coagulation of dust particles in the air flow, reducing the size of the device.

The drawing shows schematically the proposed dust collector, General view.

This is due to the ejection of the jet of the irrigator 2 being sucked into the inlet part of the cylindrical body 1, where the dust particles are irrigated with water in the irrigator plume. The dust-air flow around the waterproof casing 8 enters the rotation zone of the first impeller on its blades, where part of the largest dust particles, sludge droplets and water are caught by the grooves located on

The 1Q upper and rear edges of the blades, and then under the action of centrifugal forces, breaks off the blades of the wheel, moving by inertia along the inner wall of the circular sludge outlet channel 9, is cut off by the sludge cutter 10 and falls into the sludge disposal plant 20

Another part of coarse particles, droplets of sludge and water, as well as fine-dispersed flow in a twisted form passes through the spraying apparatus 6, in whose slot channels, due to high turbulization of the total flow, effective moistening and additional coagulation of fine-dispersed dust particles occur. This part of the dust-air flow, in the basis of the dust collector consists of a cylindrical body 1, in which an orbital forehead 11 is placed, connected to a common sludge collector 2, a swirler in the form of impellers 3, a home 12. axial fan connected to the electric motor 4 by a common shaft 5 spraying apparatus in the form of a polycylindrical humidifier 6, placed between the impellers 3 of an axial fan, the sludge catcher 7 and the waterproof streamlined casing 8 of the electric motor 4. The cylindrical housing 1 at the place of impeller impeller 3 The fan and spraying apparatus 6 is made in the form of a circular coarse-dispersed, gets into the zone of the slurry disposal channel 9 from the location of the second impeller 3 on its bottom cutter 10 of the blade, where the scoop Also, the gallant is connected to the sludge-removal chute by the pubes 13 and 14, is thrown onto the inside 11 with the common sludge outlet 12. Blades, the injured walls of the circular sludge-removal barrel wheels 3 of the axial fan from the stationary channel 9, is cut off with the sludge cutter 10 ROES sprinkler 2 have grooves, with 30 and from the length of the grooves of the trailing edges of the 13 blades into the common sludge channel 12. constitutes the fifth part of their length, and the grooves are not captured in the working area of rotation

the upper edges 14 are located at an angle of the wheel part of the dust-air flow 65-70 ° to the trap of the trailing edge 13. The impermeable streamlined casing 8 flows into the sludge trap 7 when it moves further in the dust collector, where the inlet 15 and the outlet 16 branch pipe 35 The final cleaning of the dust is effected, which are necessary for cooling the electric motor 4. from drops of sludge, water and dust particles.

The dust collector works as follows: both fall into the total sludge outlet 12, and the cleaned air is discharged into the mountain atmosphere.

The dusty air under the action of rotation through the outlet part of the dust-collecting impellers 3 axial fans.

This is due to the ejection of the jet of the irrigator 2 being sucked into the inlet part of the cylindrical body 1, where the dust particles are irrigated with water in the irrigator plume. The dust-air flow, a streamlined waterproof casing 8, gets into the rotation zone of the first impeller on its blades, where a part of the largest dust particles, sludge droplets and water is caught by the grooves located on

the upper and rear edges of the blades, and then, under the action of centrifugal forces, breaks off the blades of the wheel, moving by inertia along the inner wall of the circular sludge outlet channel 9, is cut off by the sludge cutter 10 and enters the sludge removal chute 11 connected to the common sludge disposal unit 12 The coarse-dispersed, gets into the rotation zone of the second impeller 3 on its paddles, where the stream is also caught by the canals 13 and 14, is thrown onto the inner walls of the circular sludge channel 9, cut off by the sludge cutter 10 and removed chute 11 into the common squeeze channel 12. It is not captured in the zone of rotation of the working

Another part of coarse particles, droplets of sludge and water, as well as fine-dispersed flow in a twisted form passes through the spraying apparatus 6, in whose slot channels, due to high turbulization of the total flow, effective moistening and additional coagulation of fine-dispersed dust particles occur. This part of the dust-air stream, in the base 11, connected to the common sludge discharge 12. coarse-dispersed, falls into the rotation zone of the second impeller 3 on its blades, where the stream is also caught by the cans 13 and 14, is thrown onto the inner the walls of the circular sludge outlet channel 9, is cut off by the sludge cutter 10 and retracted by the sludge outlet chute 11 into the common sludge outlet channel 12. Unclassified in the zone of rotation
