Description

() циклон() cyclone

II

Изобретение относитс к технике очистки газов и может быть использовано в аспирационных и пневмотрэнспортных системах, например в промышленности строительных материалов дл очистки газа при производстве керамоперлита .The invention relates to a technique for the purification of gases and can be used in aspiration and pneumatic export systems, for example, in the building materials industry for the purification of gas in the manufacture of ceramoperlite.

Известен циклон, включающий цилиндро-конический кЬрпус с сепарациоиными пылеотвод щими каналами, расположенными вдоль образующих циклона, и отсекающие козырьки на внутренней поверхности 1 .A cyclone is known, including a cylindrical-conical crusp with separating dust-collecting channels located along the cyclone-forming parts, and cut-off visors on the inner surface 1.

Недостатком указанного циклона вл етс то, что угол между направлением потока наиболее запыленного сло газа и осью канала равен 90, поэтому удаление уловленной пыли происходит под действием силы т жести, энерги}} газового потока дл удалени уловленной пыли при этом не используетс . Вследствие этого возможен повторный уносThe disadvantage of this cyclone is that the angle between the direction of flow of the most dusty gas layer and the axis of the channel is 90, so the removal of collected dust occurs under the force of gravity, energy}} of the gas stream to remove the collected dust while not being used. As a result, re-entrainment is possible.

пыли и снижение эффективности очист ки.dust and reduced cleaning efficiency.

Известен также циклон дл очист ки газа от пыли, содержащий корпус, выполненный в виде винтовой спирали с входным боковым и осевым выходным патрубками, винтова спираль которого образует пылеотвод щие каналы, открытые внутрь корпуса 2.A cyclone for cleaning gas from dust is also known, comprising a housing made in the form of a helical coil with inlet side and axial outlet nozzles, the helix coil of which forms dust-removing channels open into the interior of case 2.

Энерги газового потока дл отво10 да пыли в таком циклоне используетс , но так как каналы полностью открыты внутрь корпуса, уход щий из циклона газ увлекает за собой мелкие частицы пыли, а эффективность The energy of the gas stream for removal of dust in such a cyclone is used, but since the channels are completely open into the body, the gas leaving the cyclone carries small particles of dust, and the efficiency

15 очистки газа из-за повторного уноса снижаетс .15 gas cleaning due to re-entrainment is reduced.

Цель изобретени - увеличение эффективности очистки газа.The purpose of the invention is to increase the gas cleaning efficiency.

Claims

20 in that in a cyclone for cleaning gas from dust, comprising a housing made in the form of a helical coil with inlet side and axial outlet nozzles, the coil coil of the housing is made with overlapping turns and with a diameter increasing from top to bottom. Fig, 1 shows the proposed cyclone, a general view; in fig. 2 section A-A in FIG. one; in fig. 3 section bb in fig. one; in fig. clone, axonometric projection. The cyclone includes a cylindrical-conical body 1, the walls of which form a spiral coil, a side inlet 2 and an axial exhaust pipe 3. The overlapping coils of the spiral wall of the cyclone body form a helical separation dust separation channel k, with STOM the overlap is 0.020, 1 diameter cylindrical cyclone body parts. The cyclone works as follows. Dust gas enters the cycle through the side inlet 2 tangentially, therefore twisting. Under the action of centrifugal dust, it presses against the spiral wall and enters the separation canal k. Due to the fact that the separation channel is located along a helical line, i.e. at an angle to the direction of flow, dust particles concentrated in the outer layer of the rotating gas stream, mouth 7. 4 rem / 1 are along the duct down into the dust collector under the combined influence of gravity and dynamic pressure of the gas flow, and the purified gas through the axial outlet pipe exits the cyclone. In the proposed cyclone, gas cleaning is provided more efficiently, since the dust-laden gas moves along a screw channel fenced off from the purified flow by the wall, hence the re-entrainment of dust is excluded. Claims of the Invention Cyclone for cleaning gas from dust, comprising a housing made in the form of a helical spiral with inlet side and axial outlet pipes, so that, in order to increase the efficiency of gas cleaning, a spiral helix the body is made with overlapping turns, and with a diameter increasing from top to bottom.
