Abstract

The invention relates to a device for cleaning gases from solid dust particles using centrifugal force and allows for increasing the degree of purification of dusty gas by eliminating its entry into a dust collector. The increase in gas cleaning degree is achieved due to the fact that a reflector is installed in the housing 2 in front of the dust collector 7, which is made in the form of star-shaped blades 8 and 9, vertically mounted blades 8 and 9, half of which, through one, interact with the wall of the housing 2 by the upper part 10 side edges, and the rest - the bottom part 11. The upper edge of the blade 8 is made with a slope to the center of the reflector, and the upper edge of the blades 9 - with a rise to it and bent in the direction of rotation of the vortex gas flow The highest points of the upper edges of all blades are located at the same level. The blades 8 inhibit the wall pshagazgaz stream, do not interfere with the meeting of pshn in the dust collector 7 and provide additional loss of dust in the calm formed behind them, and the blades 9 with bent upper edges throw the cleaned gas to the exhaust nozzle 4. 1 zp. f-ly, 3 ill.

The invention relates to devices for cleaning industrial gases from solid dust particles (pshi) contained in them using centrifugal force, in particular to cyclones, and can be used by mining, coal, metallurgical, energy and many other industries. - ti.

The purpose of the invention is to increase the degree of purification of dusty gas due to the exclusion of its entrance into the compactor.

1 shows a cyclone, a partial section; figure 2 is the same, top view; on .fig.Z - section aa in figure 1.

The cyclone contains a cylinder-conical case 2 mounted on frame 1 with a tangential inlet 3 and central exhaust 4 nozzles and a dust outlet 5, and also attached to the case using the quick-release clamp 6 in the case 7 and a reflector made in front of it in the case vertically mounted blades 8 and 9, which interact with the side wall of the housing, are blades 8 with the upper part 10 of the side edge, and blades 9 with the lower part 11 of the side edge, so that the reflector is centered and held back in the cyclone body 2 by seizure. The upper edge of the blades 8 is made with a slope to the center (axis) 12 of the reflector, and the upper edge 13 of the blades 9 - with the rise to it and bent in the direction of the vortex

eliminating its rotation by a vortex gas flow. All this ultimately provides an increase in the degree of gas purification by the cyclone as a whole.

By the variously inclined position of the upper edges of the blades with the same height of their highest point, the process of separating dust from the gas at the periphery of the reflector is enhanced by intensifying the deceleration of the piezo-gas flow before the high blades in this place and deepening them calmly behind them. blades accelerates the removal of purified gas from the reflectors both at the periphery and in the price of it.

The cyclone works as follows.

For operation, the cyclone is connected with a tangential nozzle 3 to a source of dusty gas, and a central nozzle 4 is connected to an exhaust valve (not shown). Dust gas through a tangential nozzle 3 with a high (more than 20 m / s) velocity enters the cylindroconical case of the 2nd cyclone and acquires in it a rotation-downward (vortex) motion. At the same time under the action arose During rotation of the centrifugal force, the dust particle is thrown to the wall of the housing 2 and moves along it to the dust outlet 5, and the cleaned gas, cleaned from dust, is centered in the center of the housing 2 and rotates upwardly to the central exhaust gas

The highest points of the upper edges of the blades are located at the same level.

By refining the reflector in the form of vertically mounted blades star-connected with each other and by contacting half of them, through one, the upper part of the side edge with the wall of the body, the penetration of the vortex flow of dust-laden gas into the glass collector is prevented due to the presence of obstacles in its path they calm down, creating additional conditions for centrifugal discharge from the flow (separation) of the gas flow, and by contacting the second half of the blades with the lower part of their side edge, with centering and wedging of the reflector in the housing.

eliminating its rotation by a vortex gas flow. All this ultimately provides an increase in the degree of gas purification by the cyclone as a whole.

A versatile inclined position of the upper edges of the blades at the same height of their highest point provides additional strengthening of the process of separating dust from gas at the periphery of the reflector due to increased braking of the piechegas flow before the high blades in this place and the deepening of the upper blades of the upper blades accelerating the removal of purified gas from the reflector both at the periphery and at its center.

The cyclone works as follows.

For operation, the cyclone is connected by a tangential nozzle 3 to a source of dust gas, and a central nozzle 4 is connected to an exhaust fan (not shown). The dust-laden gas passes through the tangential nozzle 3 with a high (more than 20 m / s) velocity into the cylindrical body 2 of the cyclone and acquires a rotation-downward (vortex) motion in it. In this case, under the action of centrifugal force, the dust particle is thrown to the wall of the housing 2 and moves along it down to the dust outlet 5, and the cleared gas freed from dust concentrates in the center of the housing 2 and rotates upwardly to the central exhaust The air is released into the atmosphere or enters a process. Income to the reflector, gas-vortex downward flow

the blades 8 and 9 of the reflector are braked and due to this its penetration into the dust collector 7 is excluded. At the same time, after separating the gas from the gas, the blades 8 stop rotating in front of the high periphery blades and, moving down the wall of the housing 2, fall into the chamber 7 Partial contacting of the lateral edges of the blades with the wall of the body does not prevent the movement of the plush into the dust collector. The gas cleared from drinking because of its deflection by the bent edges of the blades 9 gets accelerated advancement to the outlet nozzle 4.

When the gas flow moves over the reflector in its central part, the blades 8, due to the low location of their upper edges, do not interfere with the movement of gas, and at the periphery the dust-gas flow encounters obstacles in its path — the high upper edges of the blades 8 — and moves slowly due to stopping before an obstacle and its bypass. The acceleration of the inlet and central exhaust vane movement of the vortex flow over the reflector in its center and slowed down at the periphery is facilitated by the location at the same level of the highest points of the upper edges of the 8 J5 and 9 blades, which ensures an optimum difference in their heights in the center and at the periphery. Stopping the gas flow before the blades 8 and changing direction

logging and with a dust outlet in the conical part, a dust collector and a reflector installed in front of it, which differs from the fact that, in order to increase the degree of cleaning of the dusty gas by eliminating its entrance into the dust collector, the reflector is made in the form of a star-like joint with each other vertically rounding the blades of 8.20 rolled blades, half of which also formed behind them in front of the low top of the bent edge of the 13 blades 9 calm contribute to the loss of the pie from the pepegazovogo flow before the blades 8 and behind them, in view of which the degree of gas cleaning from dust is increased.

The presence of a reflector in the design of the cyclone of a star-shaped reflector with uneven blades eliminates the penetration of the vortex pypegaz flow into the dust receiver, so that it can have small overall dimensions.
