Technical scheme unit disposal ability of the present invention and needle rotor security-related can reach 20000m
3The treating capacity of/h will reach the mode that big treating capacity can also be taked multi-machine parallel connection.
Useful effect:
1, compare with multicyclone with traditional cyclone dust collectors, baffle and reflux type coupled filtering centrifuger has several like this advantages.At first, tangential admission is faced when having covered the air intake filter of whole inner chamber, form and slow down, add that the hole that particle momentum direction and air-flow will pass intersects to wide-angle, force most of bulky grain thing to separate and sedimentation, be isolated to beyond the filter, also make the air-flow that enters the strong whiz chambers of the heart and the thin material that carries can be in ring Zhou Gengjia diffusion profile equably.Secondly, in baffle and reflux type coupled filtering centrifuger, under rotor drives, the linear velocity that obtains through the particle that enters centrifugal chamber behind the filter can reach 30 ~ 100m/s, even it is higher, be higher than the intake velocity level of 18 ~ 25m/s of cyclone dust collectors far away, dust removal performance increases substantially, and becomes the high-effective dust-removing technology.Its three, the axial symmetry in centrifugal chamber is better, material in centrifugal chamber, encircle the week distribution more even, be beneficial to centrifugation.Its four, the auxiliary a part of mist pearl of semi-dry desulfurization is to capture, the polymerization of subparticle, the effect that suppresses its up discharge is remarkable.
2, compare with Deutsche Bundespatent Wirbler-Filter-Kombination zum Absheiden von Gasenoder Daempfen dispergierten Teilchen (patent No. DE 4033729 C1), baffle and reflux type coupled filtering centrifuger rotor dynamic balancing, scalable property, service life all are significantly increased.The filtrate of baffle and reflux type coupled filtering centrifuger is a stator, and equipment resistance increases with rotor speed unlike rotating cylinder one class technology.In addition, the filtrate of baffle and reflux type coupled filtering centrifuger directly is subjected to the effect of centrifugal inertial force unlike rotating cylinder, so filtrate Material Selection leeway is much bigger.
3, the import wind speed of baffle and reflux type coupled filtering centrifuger can be in the level of 10 ~ 14m/s, unnecessary 18 ~ the 25m/s that reaches cyclone dust collectors, the flow structure resistance drop of turning back of centrifuge is low to moderate below the 600Pa, also below 300Pa, the amplitude that the SR of baffle and reflux type coupled filtering centrifuger increases mainly is the size of filter opening to additional drag when rotor moves with 3000 rev/mins of speed.Because the major function of filter does not lie in the filtration micronic dust, and be can ring week more equably cloth wind, distribute material content, the filtrate filter opening can be greatly.When filter opening during greater than 20 μ m, the resistance that filtration system increases is below 100Pa, and drag overall is below 1100Pa.And the return stream deduster of the mechanical type of all rotating cylinder rotor structures is when rotating speed reaches 2000 ~ 3000 rev/mins, and resistance just reaches 1400 ~ 2800Pa.
4, the baffle and reflux type coupled filtering centrifuger wear-out life is very long.Air-flow enters cyclone head and encircles filter later on and distribute, and enters moderating process, and the larger particles part inertial settling in the waste gas, a part can't the contact filtration devices under the aerodynamic force effect, or is filtered sedimentation downwards under the gravity effect then by filter cylinder.The design inlet velocity of baffle and reflux type coupled filtering centrifuger is controlled at below the 12m/s, and is more much smaller than the particle initial momentum under whirlwind deduster 18 ~ 25m/s inlet velocity.So the wearing and tearing of air inlet section are smaller.Under the shielding of filter, the particle of whereabouts is not quickened the chance of rotation by center rotor, thereby the housing that can not wear and tear.The particle monomer whose mass ratio that passes filtrate is less, and it is little to be quickened back wearing and tearing ability by pinwheel 4 again.The factor of decision tear strength is the momentum of particle, and momentum is the long-pending of quality and speed.The abrasion of particles ability that particle diameter is more little is more little.Therefore, the wear-out life of rotor is then long to can not changing throughout one's life.The emphasis abrading section of baffle and reflux type coupled filtering centrifuger is a filter cylinder, and the rule of its wearing and tearing is that the aperture increases, and the performance of centrifuge is not had remarkable influence, because the design filtration velocity is less than 5m/s, so wear-out life also can be accepted.Because filter cylinder can be changed, so the wear-out life of whole centrifuge can fully satisfy production requirement.

The course of work of baffle and reflux type coupled filtering centrifuger of the present invention is: aerosol stream is cut from top air inlet 11 and is flow to into cyclone head assembly 2, forms whirlwind, and a part of bulky grain centrifugation arrives the limit wall.Deceleration after filter cylinder impels aerosol stream ring filter cylinder to distribute by the resistance of opening aperture formation sees through filter cylinder with little flow velocity, and the big particle of a part is fallen by media filtration.The particle of initial gross separation moves downward and falls into dump skip 9 collections.After aerosol stream passed filter cylinder 3, under gas off-take 12 restrictions of stretching into cyclone head assembly 2, the aerosol stream main force produced downward vortex.Meanwhile, pinwheel 4 gas off-take in filter cylinder rotates below 12, is formed with the even rotational field of unified angular speed, and the particle that sees through filter cylinder is applied maximum line velocity, forces particle to carry out downward centrifugal motion, falls into dump skip 9 gradually and collects.The gas that enters the cavity center and see through pinwheel 4 centers is purifying gas flow, discharges from changing gas outlet 15 over to after the top central core region is drawn.
When adopting the semi-dry desulfurization separating granular, water smoke at center, centrifugal chamber by atomizer 18 ejections is carried out centrifugal motion after the further refinement by eddy flow, capturing micronic dust quickens to move to the limit wall, edge dirty remittance slurry-dropping bucket 16 discharges of filter cylinder 6 imperforate section down then, or the sedimentation of gathering micronic dust directly falls into slurry-dropping bucket 16 discharges.
