Abstract

The invention relates to a technique for purifying gases from dispersed impurities and improves the cleaning efficiency. Vortex dust collector includes a housing 1 with an inlet 2 and an outlet 3 with nozzles, a hopper 4, disks 5 and 6 placed in the cavity of the hopper and mounted coaxially with the housing. The diameters of the discs are larger than the diameter of the case, and the disc 5 has a central opening. The gas supplied to the cleaning through the nozzle 2 twists in the housing 1 and moves in a descending vortex to the surface of the disk 5. Due to the centrifugal effect, the particles are concentrated near the wall of the housing and with part of the flow radially enter the hopper 4 through the gap 7, and the purified gas is turned over the disks and the ascending vortex is removed through the nozzle 3. In the area of the disk edges, the particles are separated from the gas when the cleaned flow turns, radially entering through the other gap 8 and the central hole in the disk 5 into the area of the ascending vortex. Separated particles are deposited in the hopper. 1 il.

The invention relates to a technique for the purification of gases from dispersed inclusions and can be used in energy, chemical, metallurgical, mining, construction, food and other industries.

G. Gel invention - improving the efficiency of gas purification.

The drawing shows a vortex dust collector, a longitudinal section.

The dust collector includes a housing 1 with an inlet 2 and an outlet 3 with nozzles of a hopper 4, disks 5 and 6 placed in the cavity of the hopper 4 and mounted coaxially with the housing 1 with gaps 7 and 8 relative to its edge and between themselves. The diameters of the disks 5 and 6 are larger than the diameter of the vortex chamber, and the disk 5 has a central opening.

Vortex dust collector works as follows.

The gas supplied for cleaning enters tangentially into the housing 1 through the inlet 2 and moves in a downward swirl along the axis of the housing 1 to the surface of the disk 5. Due to the centrifugal effect, the particles of the pierce are dropped to the walls of the housing 1 and with the peripheral part of the downward flow through the annular gap 7 between the edge of the body and the disk 5 radially enter the hopper 4. At the surface of the disk 5, the rest of the downward vortex flow is rotated 180 degrees, which gives rise to an upward vortex moving to the upper

an inlet 3 that serves to remove the purified gas. R corresponds to the nature of the pressure distribution in the cross section of the vortex in the bunker 4 sets a higher pressure than in the axial zone of the housing 1, which ensures a steep reversal of the radial flow flowing into the bunker 4 from the annular gap 7, the radial lines entering its gap 8 between disks 5 and 6 with simultaneous separation of the particles of the disk at the moment of rotation under the action of the forces of inertia and the outflow of gas through the central hole in the disk 5 into the zone of the ascending vortex in the direction to the outlet nozzle 3. Separated particles deposited in the hopper 4.
