Description

The invention relates to a technique for cleaning gases from dust and can be used in the industrial building materials, heat and power engineering and other sectors of the national economy in the production of powder materials. I

The aim of the invention is to increase the dust collection efficiency.

FIG. 1 shows a dust collector general view; in fig. 2 shows a section A in FIG. one.

The inertial vortex dust collector includes a housing 1, in the upper part of which there is a spiral duct 2, which passes into the central cylindrical part 3 by means of an opening 4. The vertical walls of the spiral duct are made of stake and. Sector sectors 5 arranged in such a way that the beginning of each subsequent sector it is as if it slips from the inside of the gas duct to the end of the previous sector, with the remaining radial slots 6 between the sectors. The outer wall of the spiral duct in the lower part is made in the form of cutting sheets 7, arranged in a spiral one after another with the formation of slots 8 along the vertical. The last cutting sheet is located along the concentric arc along the center along the flow. From the bottom of the cut-off sheets behind the slots, the reflectors 9 are fixed, which direct the collected dust into the bunker 10 and divide the casing into the gas-to-gas receiving zones 11 and the clean gas outlet zone 12. On the casing there are inspection hatches 13 and windows 14 for suctioning the cleaned gas through the louvered grill 15 by means of a pipe 16.

The ticking plane is the diaphragm 23. The bunker contains a lock gate 24.

Inertia-vortex dust collector works as follows.

The gas-dust flow enters the spiral duct 2, where a pressure gradient occurs between the peripheral and internal walls, which entails the formation of secondary vortices carrying the fine dust behind them, and the coarse fraction is pressed to the peripheral wall by centrifugal forces. With the gas-to-gas stream passing through the duct, the vertical components of the secondary vortices are cut off by the gas sectors 5 and through slots 6 are led into the dust-collecting channels 22, where the gas loses speed and dust is deposited in the hopper 10. At the same time, in the lower part of the duct the slots 8 of the cut-off sheets 7 direct the boundary layer of the splash into the dust-gas flow receiving zone 11, where the reflectors 9 direct the caught drink into the bunker 10, away from the clean gas outlet zone 12, preventing secondary entrainment. The spiral-bent cut-off sheets 7 smoothly narrow the cross section of the flue, which creates the conditions for effective separation. In this case, a concentrated layer of coarse and medium dust flowing down from the reflectors is a filter curtain for a thin run taken away by the transverse flow that occurs in the hopper 10 as a result of the suction of the cleaned g, ase. Next, the gas and dust flow enters the central cylindrical part 3 through the opening 4, where from the outlet nozzle 17 by means of ring sectors 18 fine dust is discharged into the dust removal channels by analogy with the spiral duct. At the flat ring 19, like at the flat bottom of cyclones, secondary vortices are superimposed on the radial drain, due to which the dust concentrates to the center line and encounters the trap 20 on the way, through the slots 21 it separates into the dust extraction channel 22 and further into the hopper 10 The purified gas is directed through pipes 17 to its intended purpose. To increase the efficiency of the separator} P1, a vacuum is created through all the slots in the bunker by sucking gases through the louvered grill 15, eliminating re-entrainment, windows 14, ensuring uniform gas suction over the cross section of the outlet zone 12 and the nozzle 16, Diaphragms 23 serve as a support for gas ducts and. These are the walls of the dust extraction channels 22. Through the inspection hatches 13, the dust catcher is serviced and repaired. Nozzles 17 are recessed to eliminate secondary entrainment.
