Abstract

The invention relates to devices for cleaning gases from dust and improves dust collecting efficiency and reduces overall dimensions. The dust collector contains a cylindrical housing 1 with a cover 2 and concentric cylinders placed in it 3. In the upper part of the case there is a tangential inlet 4, and in the lower - an outlet nozzle 5. At the level of the inlet there are tangential holes 6, and in the lower opposite part on the level outlet nozzle 5 - tangential holes forming the outlet channel, in which separating zigzag plates are placed 8. The extreme plate is placed in the side pocket. Irrigation nozzles 10 are connected to each concentric cylinder. 1 Cp f-ly, 3 ill.

The invention relates to devices designed to purify gases in various industries.

The aim of the invention is to increase the efficiency of dust collection and reduce the overall dimensions of the dust collector.

FIG. 1 shows a dust collector; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The dust collector contains a cylindrical-conical case 1 with a crush 2 and concentric cylinders 3 placed in it, with the tangential nozzle 4 in the upper part of the case 1 and the output tangential nozzle 5 in the lower part.

Concentric cylinders 3 in the upper part at the level of the inlet nozzle 4 have tangential holes 6, which form the inlet channel, and in the lower opposite part at the level of the outlet nozzle 5 - tangential outlet holes 7, forming the output channel in which the separating zigzag plates 8 are placed, extremely of which is located in the side pocket 9 of the outlet nozzle 5. The forsukki 10 irrigations are supplied to the inlet nozzle 4 and to each concentric cylinder 3.

Dust collector works as follows.

The contaminated air flow entering through the inlet 4 and the tangential holes 6 is irrigated by the nozzles 10, while the dust under the action of inertial forces falls on the wetted surface of the concentric cylinders 3 and the housing 1 and is discharged as sludge into the lower conical part of the housing 1.

Partially cleaned stream in the form of a water-air mixture, continuing spiraling and reaching the level

the outlet nozzle 5 enters the exit channel 7, is separated by zigzag plates 8 into separate jets and is additionally cleaned from water droplets and dust, and then

the outlet 5 is removed to the outside. The extreme plate, placed in the pocket 9 of the nozzle 5, provides free passage to the air.

Thus, the cleaned air

5 enters directly into the lateral tangential openings of concentric cylinders, it does not follow behind their ends, which has made it possible to reduce the height of the device.
