Description

The invention relates to the field of gas cleaning from dust and can be used in various industries

The aim of the invention is to increase the productivity of the battery cyclone in terms of flow rate of the gas to be purified.

In FIG. 1 shows a general view of a battery cyclone in a conventional arrangement; in FIG. 2 is a general view of a battery cyclone when it is arranged in an upward gas duct; in FIG. 3 is a cross-sectional view of a battery cyclone; in FIG. 4 is a sectional view of a flow divider with the placement of gas supply and dust extraction channels therein at the same time.

The battery cyclone comprises a dust bin 1, vortex chambers 2. separated by flow dividers 3, the walls of which are concave (see Fig. 3) along the radius of the cylindrical surfaces forming the vortex chambers 2. In the flow dividers 3, gas inlets 4 and dust channels 5 are arranged. Swirl chambers 2 have top 6

and / or lower 7 swirls, P house one hundred-; The swirling swirls and swirl chambers have the counter rotation indicated in FIG. 3 arrows. Vortex chambers 2 communicate with each other. They are connected from above by gas exhaust pipes 8 to the purified gas manifold 9 (to the upper part of the ascending gas duct), through swirls 6,7 and gas supply channels 4 with gas supply nozzles 10 to the cleaned gas inlet chamber 11 (to the lower part of the ascending gas duct) and dust extraction channels 5 through dust-receiving slots 12, swirlers 13 to dust-receiving cyclones 14 or directly to the dust bin 1. The dust receiving slots 12 are located opposite the gas supply nozzles 10 at the corners of the flow dividers 3, oriented towards the incident vortices (see Fig. 3) and have baffle plates 15 installed with an inclined downward direction. In this case, the dust extraction b A can be isolated by partitions 16 in one flow divider 3

5 channels and 4 gas supply channels, as shown in FIG. 4. The gas supply nozzles 10 are slanted downward. The lower swirls 7 have a smaller diameter than the swirl chambers 2 and are installed in the axial nozzles 17. Under the swirl chambers 2 there are dust collection cyclones 14 connected by swirls 13 to the dust extraction channels 5, gas outlets 18 to the lower central part of the swirl chambers 2 and dust-collecting channels 19 to the dust bunker 1.

Suction cyclones are not located under each vortex chamber. In FIG. Figure 1-3 shows the installation of one suction cyclone for every four vortex chambers. In this case, the number of dust channel 19 is reduced by 4 times, respectively. In this case, the space under the battery cyclone is freed up, and when installing the lower swirlers 7, it is possible to arrange it in the inlet duct, as shown in FIG. 2, without installing rotary flues. At the same time, the productivity of the battery cyclone in the gas to be cleaned is increased, since when flowing in swirl chambers, higher axial velocities are allowed.

The proposed battery cyclone operates as follows.

Dusty gas from the cleaned gas inlet chamber 11 (lower part of the upward gas duct) through the upper 6 and / or lower 7 swirls and gas supply channels 4 with gas supply nozzles 10 is introduced into the vortex chambers 2 with an intensive swirl of the vortex flow, rotating counterclockwise, as shown in fi g. 3. In this case, due to centrifugal forces, the center of the vortices is cleaned of dust particles. The purified gas is vented. from the center of the vortex chambers 2 through the exhaust pipes 8 to the cleaned gas manifold 9 (to the upper part of the ascending gas duct). Dust particles are concentrated in the wall layer. The flow of gas flowing out of the gas supply nozzles 10 installed obliquely downward, the dust is blown off and at the same time it is separated through the dust collection slots 12 into the dust removal channels 5. Between the dividers 3, the flows in the zones of overlapping of the vortex chambers 2. the vortices collide, particles dusts collide and intensively coagulate, i.e. become larger due to coalescence, and the uneven distribution of energy of the vortices, due to the unevenness of the input conditions, is equalized, which increases the efficiency of particle capture. The trapped dust through dust extraction channels 5 is poured directly down to the dust bin 1 or enters there with a stream of recirculating gases through suction cyclones 14, as shown in Fig. 1,2. At the same time, the baffle plates 15 prevent the removal of dust collecting dust falling down. The dust collecting cyclones 14 operate under the influence of the differential pressure present in the rotating stream. The pressure in the dust receiving slots 12 due to the inhibition of the incoming dusty stream is increased, and the flow enters through the snail swirl 13 into the dust collecting cyclone 14, where it is cleaned of dust. The purified gases are sucked out through the exhaust pipe 18 to the discharge zone formed in the center of the vortex chamber 2. The captured dust enters the dust bin 1 through the dust channels 19. From there it is discharged as it accumulates.

Thus, the productivity of the battery cyclone in terms of the flow rate of the cleaned gas is increased by:

- involving the volume occupied by the flow dividers into the work when placing gas supply and dust removal channels in them;

- the possibilities of arranging it in an upward flow, where, due to flow in the vortex chambers, higher axial velocities are allowed.
