Description
Technical field
The present invention relates to a kind of cyclone separator, comprise: a cyclone separating chamber formed by column body segment and cone segments that inside is cavity, the recovering hopper be connected with the cyclone separating chamber cone segments, along column body segment tangential that arrange and the air inlet column body segment intracavity inter-connection, be positioned at the central exhaust outlet on column body segment top.
Background technology
Cyclone separator is a kind of common device separated from the gas of the particle for by gas, its basic structure by: inside is the cyclone separator be comprised of column body segment and cone segments of cavity, the recovering hopper be connected with the cyclone separator cone segments, along column body segment tangential that arrange and the air inlet column body segment intracavity inter-connection, and the central exhaust outlet that is positioned at the column body segment top forms.Cyclone separator is one of most widely used equipment, has a device structure simple, and volume is little, and manufacturing expense is low, safeguard, repair convenient, be easy to lay wear-resisting, corrosion resisting liner, but the purification of corrosive dust, and characteristics such as long service life.But the cyclone separator in use useless pressure loss is larger, affect the effect of its use.The useless pressure loss that how under the prerequisite that guarantees separative efficiency, to reduce separator is the problem that will solve present stage.
Summary of the invention
The invention provides a kind of prior art deficiency that overcomes, can guarantee separative efficiency, reduce the cyclone separator of the useless pressure loss.
The cyclone separator of the broken wing of built-in vortex core of the present invention comprises: the inside be comprised of column body segment and cone segments is cavity, cross section is the cyclone separating chamber of circle, the recovering hopper be connected with the cyclone separating chamber cone segments, along column body segment tangential that arrange and the air inlet column body segment intracavity inter-connection, be positioned at the central exhaust outlet on column body segment top, central shaft position along cyclone separating chamber in cyclone separator is provided with a fixed axis, the lower end of fixed axis is positioned at 1/2 place of taper contraction section, is provided with the broken fin of vortex core of fixed axis on fixed axis.
In the cyclone separator of the broken wing of built-in vortex core of the present invention, the floor projection length of the broken fin of vortex core be approximately equal on cyclone separating chamber's longitudinal profile geometric center to forced vortex the twice with free vortex intersection distance, the product of the broken fin width of vortex core and fin quantity is greater than the zero fixed axis length that is less than.
In the embodiment of the present invention, the broken fin of vortex core that is positioned at separation chamber column body segment part is that length is approximately equal to 1/6 the rectangular block that is approximately equal to the fixed axis diameter for central diameter of outlet, thickness; The broken fin of each vortex core of cyclone separating chamber cone segments part be length be approximately equal to its cross circular section diameter of living in 1/2, width is approximately equal to 1/6 the rectangular block that fixed axis length 1/23, thickness are approximately equal to the fixed axis diameter.Need the present invention of special instruction and the thickness of the broken fin of vortex core to have no special requirements, only require that its thickness can keep certain rigidity, the unlikely failure damage that in use occurs gets final product simultaneously.
In the cyclone separator of the broken wing of built-in vortex core of the present invention, the setting position that is arranged at the broken wing of fixed axis vortex core topmost should, slightly lower than the lower edge of central exhaust outlet, be positioned at the lower end of a little higher than fixed axis of the broken fin setting position of fixed axis vortex core bottom.
In the cyclone separator of the broken wing of built-in vortex core of the present invention, be provided with the broken wing of 8 vortex cores on its fixed axis, and broken interplane every two the equidistant quadrature arrangement of adjacent fin of each vortex core, the diameter of fixed axis is 1/2 of cone segments lower ending opening diameter, and the fixed axis lower end is positioned at 1/2 place of cyclone separator cone segments.
Correlative study shows, in cyclone separator when work, exist the inward eddy air-flow (be also referred to as forced vortex) mobile to central exhaust outlet in heart zone therein, in the cyclone separator central area to existing between the cyclone separator barrel along the outer eddy flow (being also referred to as free vortex) that separates the body wall rotational flow.Research also shows that the pressure loss of cyclone separator is mainly determined by the forced vortex of inward eddy, and separative efficiency is mainly determined by the free vortex of outer eddy flow.The pressure loss and separative efficiency are to weigh the leading indicator of Separation Performance of cyclone Separators, so, under the prerequisite that guarantees separative efficiency, the pressure loss that reduces the separator central area is to improve a key point of cyclone separator.
Technical solution of the present invention is: the built-in not kinetoplast consisted of fixed axis and the broken fin of vortex core that invests in the forced vortex zone of the cyclone separating chamber center of cyclone separator, replace and destroy forced vortex with kinetoplast not, to reduce the pressure loss.The length of the broken wing of the fixed axis in the present invention and vortex core and to be distributed in be to design according to forced vortex and free vortex position and shape in theory, the broken fin length of set vortex core should equal on the cyclone separator longitudinal profile geometric center to the twice of forced vortex and free vortex intersection distance in principle, make the broken fin of fixed axis and vortex core in inward eddy, its effect is both to have destroyed the inward eddy forced vortex, reduce the pressure loss, do not destroy again outer eddy flow free vortex, affect its collection efficiency simultaneously.According to related experiment, the edge of the broken fin of vortex core preferably is positioned at the intersection of forced vortex and free vortex, should retain as far as possible the large shared space of outer eddy flow simultaneously, to reduce, flowing of air-flow formed to obstruction with the whereabouts of particulate matter, meeting under this prerequisite the shape of the broken wing of vortex core and the restriction that setting there is no other.
Just because of this reason, in conjunction with the above-mentioned architectural feature of characteristics formation the present invention of existing cyclone separator.
The present invention by cyclone separator to the interior broken fin of vortex core that arranges, reduced the zone of forced vortex, weakened forced vortex intensity, also reduced the pressure loss simultaneously, energy consumption in the time of can reducing cyclone separator work, and the present invention is simple in structure, easily realize, be convenient to existing apparatus is transformed.
