Phi2.1

This invention relates to devices for collecting dust from gas streams.

The purpose of the invention is to increase the efficiency of dust collection and to enable fractional separation of non-uniform dust.

FIG. 1 shows a dust separator in diametric projection, a section; in fig. 2 - the same, top view; in fig. 3 - pipe for dust removal, incision; in fig. 4 - dust separator with removed housing (propeller blade).

The device for separating dust comprises a housing 1 with a cover 2 and a bottom 3, a tangential nozzle 4 for introducing a vacuum.

nozzle 5. Regulators 6 are designed to limit the escape of gas along with dust.

On the last turn of the screw blade (located near cover 2), the gas cleaned of dust is removed from the dust-separator through the tangential nozzle 8. The number of sections of the tangential nozzle 5 (to remove dust from the dust separator) is one less than the number of turns of the helical blade, because on the last (from bottom 3) turn of the helical blade there is a tangential nozzle 8 for the output of clean gas.

The proposed device for the separation

heterogeneous dust by fraction

Claims (3)

Invention Formula The gaseous gas, sectional tangential dust 15 makes it possible to increase the efficiency of the nozzle 5 for dust extraction, each separation, and to ensure the separation of which is equipped with slit width adjusters 6, a tangential nozzle 8 for clean gas output, a screw blade 9 reinforced on the pipe 10. The device works as follows. Gangentia-1 dusty gas flow. A device for separating dust, the common pipe 4, located under the supporting cylindrical body with the bottom 3, enters the walls 1 at high speed inside the body, the bottom, into the body 1. At the same time, the dust particles under the cover, the pipe for the output of clean gas, centrifugal Forces reject — 25 tangential nozzles for injecting dust into the walls of the body in the zone of the first vitrified gas and dust outlet, characterized by the spiral blade 9, forming a near-wall beam, in order to increase the efficiency with a small amount of gas is removed from the dust separator through the formed by regulating, it is equipped with a pipe installed in the housing, the partitions are made in the form of coils attached to it L torus 6, the slit 7 in the first (from the bottom) 30 screw blades, and the nozzle for input section of the tangential nozzle 5. Partially purified gas continues to move, moving to the next turn of the helical blade, where by reducing the cross section of the passage (obtained by the fact that the screw blade is fixed on the pipe with a diameter of 35 rms increasing in the direction from the days of Qia 3 to the flap 2), it is accelerated, with the centrifugal force increasing, as a result of which it is thrown to the walls of the casing from the gas flow (released Q to remove dust. The dust-laden gas is made with a height equal to the pitch of the helical blade, and is located above the bottom, while the diameter of the pipe increases in the direction from the bottom to the cover. 2. The device according to claim 1, characterized in that the nozzle for outputting clean gas is made tangential with a height equal to the shaft of the helical blade, and is positioned over the tangential pipe. from larger and heavier dust on the previous turn of the screw blade) a smaller and lighter part of the dust, which, in turn, is removed from the dust separator on this turn of the screw blade through the corresponding 3. A device according to claim 1, characterized in that, in order to enable fractional separation of non-uniform dust, the tangential nozzle for dust extraction is sectioned with a height, the corresponding section of the tangential 45 is up to a section equal to the pitch of the helical blade. 0 nozzle 5. Regulators 6 are designed to limit the escape of gas along with dust. On the last turn of the screw blade (located near cover 2), the gas cleaned of dust is removed from the dust-separator through the tangential nozzle 8. The number of sections of the tangential nozzle 5 (to remove dust from the dust separator) is one less than the number of turns of the helical blade, because on the last (from bottom 3) turn of the helical blade there is a tangential nozzle 8 for the output of clean gas. The proposed device for the separation 5 dust allows to increase the efficiency of dust collection, as well as to ensure the separation of heterogeneous dust by fraction dust allows to increase the efficiency of the heap, as well as provide Invention Formula It enhances the effects and also provides it is equipped with a pipe installed in the housing, the partitions are made in the form of coils reinforced on it  screw blade, and a nozzle for input for dust removal. The dust-laden gas is made with a height equal to the pitch of the helical blade, and is located above the bottom, while the diameter of the pipe increases in the direction from the bottom to the cover. 2. The device according to claim 1, characterized in that the nozzle for outputting clean gas is made tangential with a height equal to the shaft of the helical blade, and is positioned over the tangential pipe.  for dust removal. 3. The device according to claim 1, characterized in that, in order to enable fractional separation of non-uniform dust, the tangential nozzle for dust extraction is sectioned with a height of 4 cm. 2 Fig.Z
