6, device is interior by aeration parts 21 of being made up of annular aeration head, valve, pipe joint, sealing nut, tracheae etc., is placed in bearing housing 2 ends, or is connected on jointly on the multilayer standpipe 9 with jet head 7.
The length in centrifugal chamber 8 is closely related with rotor speed in technical solution of the present invention one and the technical scheme two, the high more centrifugal chamber of rotor speed 8 length can obtain more little, thereby centrifugal chamber 8 length can become between in outlet diameter 3～20 times, do the ratio of dedusting section and the shared centrifugal chamber of absorption and separation section 8 length and can regulate.The length of doing the dedusting section should be greater than centrifugal chamber 8 diameters.The length of absorption and separation section should be greater than gas off-take 12 diameters.
Technical solution of the present invention can realize following useful effect.
1, do wet discharging separately after, little and amount is few because of the dirt particle that need capture in centrifugal chamber 8 the second halfs, although spouting liquid is little, still enough greatly, the slurry stream kinetic force is strong, has just eliminated possibility of jamming for the ratio of mud.So under less spouting liquid, can ensure the reliability of semi-dry desulfurization high-effective dust-removing industry long-time running.
2, centrifugal chamber 8 first half terms are used for dedusting, and the second half is used for separating micronic dust, absorbs pernicious gas and separate absorbent product and remaining absorbent.The strong cyclone that pinwheel 5 rotors start further discrete from atomizer water or during absorbent its most of energy be delivered to the liquid grain, both realized demist, reduced the invalid discharging of spinning momentum again.The coupling energy of dedusting and absorption reduces the one-time investment of waste gas purification greatly under the prerequisite of efficient absorption, significantly reduce installation, operating cost, thereby can bring considerable economic and social benefit.
3, apparatus of the present invention have realized low wearing and tearing.Technical solution of the present invention opens the superposition that revolves influence once preliminary whirlwind that utilizes the spiral inlet chamber and pinwheel 5 rotors makes the larger particles in the waste gas realize fully separating in the inlet chamber section.Under the cooperation of snail ring 20, the ring week zone (except that the import position) that the inlet chamber snail encircles beyond 20 internal diameters is time eddy flow district, spinning momentum increases with radius and decays, add that this district's particle aggregation forms the stratum granulosum shielding, the momentum of particle consumes a part because interfere mutually, thereby the ability of actual friction inlet chamber wall is just much smaller.When seeing through snail ring 20 whereabouts, the bulky grain of weak momentum under the shielding of lining body 6, can not from pinwheel 5 rotations, obtain bigger momentum, thus also very limited to the wearing and tearing in centrifugal chamber 8.The present invention designs inlet velocity and is controlled at below the 14m/s, and is also littler than the particle initial momentum under whirlwind deduster 18～25m/s inlet velocity.Be expected to drop to the scope of per second number meter through the speed of the stratum granulosum shielding back granule impact inlet chamber wall in time eddy flow district.All about 14m/s, its wear-out life can be accepted the experience design current velocity of general flue.The wear extent of apparatus of the present invention is lower than conventional flue.
The preliminary whirlwind that technical solution of the present invention two is utilized eccentric air inlet opens the superposition that revolves influence with pinwheel 5 rotors makes the larger particles in the waste gas just realize that at air inlet fully separating arrival serves as a contrast body 6 for 3 sections, part is passed lining body 6, fall to entering the grey storehouse of collection after momentum is decayed significantly, they do not produce wearing and tearing to centrifugal chamber 8, top, pinwheel 5.
To wearing and tearing contributive 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.The air-flow of apparatus of the present invention is entered into the wiping place by major part from inducing through the particle that has a large amount of wearing and tearing momentum behind the first whiz heart, its particle diameter of particle that arrives pinwheel 5 is quite little, they just form certain wearing and tearing ability again after obtaining to quicken on the necessarily big radius of pinwheel 5, this part particle that obtains the ability of wearing and tearing again arrives lining body 6 rapidly, to losing most of momentum after the certain wearing and tearing of lining body 6 generations, there are some to pass lining body 6, but fainter to the wearing and tearing in centrifugal chamber 8.Even if to the wearing and tearing of lining body 6, because the little reason of particle is faint more than cyclone dust collectors.Lining body 6 can be changed.So wear problem is fully solved apparatus of the present invention.
4, the device of technical solution of the present invention one is as if the negative pressure operation, because the slurry valve that unloads that installation or operation cause leaks out influential to demist and separating particles.Employing can be limited in the sparse zone of density of particle with leak out mobile path and outlet in the way of gas off-take 12 hypomeres and/or the punching of elbow 16 epimere rings week, as long as the hole is enough little, the particulate with certain spinning momentum just is difficult for entering elbow 16 with leaking out and discharges.So just ensuring equipment is realized the separating effect that it is intrinsic to greatest extent.
