Cyclone dust collectors are made up of air inlet pipe, blast pipe, cylinder, cone and ash bucket.Cyclone duster structure is simple, and be easy to manufacture, installation and maintenance management, equipment investment and operating cost are all lower.Its main working process is: when dusty gas enters cyclone dust collectors by tangential admission mouth, air-flow becomes circular motion from rectilinear motion, produce swirling motion, a swirling eddy part flows downwards, towards cone twist along deduster inwall, usually claims this to be outer rotational gas flow.Dusty gas produces inertial centrifugal rate in rotary course, and powder dust particle relative density being greater than gas gets rid of to deduster wall.Powder dust particle, once contact with deduster wall, just loses radial inertial force and momentum under being close to and gravity fall along wall, enters ash bucket from dust-exhausting port.When rotating the outer rotational gas flow arrival cone declined, draw close to deduster center because of conical contraction.According to revolving moment preserving principle, its tangential velocity improves constantly, and suffered by powder dust particle, centrifugal inertial force is also constantly strengthened.When air-flow reaches a certain position, cone lower end, namely with same direction of rotation in the middle part of deduster by lower counter steer, continue shape motion of spinning, rotational gas flow in forming.Final purification gas is discharged through blast pipe, and the powder dust particle of fraction collection at large is also discharged thereupon.
But at cyclone dust collectors top board, between exhaust tube wall and cylinder inboard wall, due to the existence of radial velocity and axial velocity, local eddy currents will be formed, the instability in flow field, the dust of the eddy current that cone produces and Turbulent Flow Effects cone near wall, makes particle be not easy deposition, again be involved in upper rotational gas flow and discharged deduster, thus reduced efficiency of dust collection.
In addition, the central gas stream of cyclone dust collectors, distortion is created at conical section, be commonly called as " wagging the tail ", this phenomenon in engineering a kind of explain widely be the bottom backspin of circular cone contour stealth and on the inward eddy that revolves overlapped, swirling eddy center is by the effect of nonequilibrium force and moment, make the misalignment of the inward eddy cluster center of device, the intensity of central gas stream distortion weakens from the bottom to top gradually, form asymmetric eddy current, cause pressure at both sides difference to define the power of air-flow transverse movement, finally make gas column depart from center.For the region that dust is the most concentrated, cone dust-exhausting port, eccentric air-flow can touch wall thus be kicked up by the dust granules be separated, and forms the reentrainment of dust phenomenon at dust-exhausting port place.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of cyclone dust collectors of high dust removal efficiency, comprise air inlet pipe 1, blast pipe 2, cyclone body 3 and ash bucket 4, described air inlet pipe 1 and blast pipe 2 are located at side and the top of cyclone body 3 respectively, described ash bucket 4 is located at cyclone body 3 bottom, described cyclone body 3 comprises large cylinder cylindrical shell 5, cone 6 and little cylinder cylindrical shell 7, be provided with the inverted round stage 8 that external diameter is less than little cylinder cylindrical shell 7 diameter in described little cylinder cylindrical shell 7, described inverted round stage 8 times square sets have positive round platform 9.
