Logical, the bottom of the cylinder 1 offers discharge outlet 16, and the bottom of the cylinder 1 offers water inlet 17.
1 outer diameter φ 315mm- φ 450mm of cylinder, internal diameter φ 305mm- φ 440mm, using two-stage vane device, fan
The blade of leaf 5 and the outer blade diameter of flabellum 7 are all φ 290mm- φ 430mm, arrange that 18 blades, heart pipeline are φ
160mm–φ250mm.800pa cannot be greater than by restraining dedusting demister total pressure drop, gone to meet according to reasonable design, reached
To optimum efficiency, dedusting demister scene running temperature is restrained between 40 DEG C -80 DEG C.
Specifically, the angle of blade on the first order flabellum 5 and smoke backflow pipe 8 is 30 ° -60 °, described second
The angle of blade and smoke backflow pipe 8 on grade flabellum 7 is 30 ° -45 °, and first order flabellum 5 and second level flabellum 7 is arranged, can
To improve the flow velocity of flue gas, the separating effect to liquid and dust on flue gas is improved.
It is uniformly distributed specifically, the through-hole 14 in the cylinder 1 and fixed plate 10 is set as equilateral hexagonal.Multiple cylinders are set
Absorption tower can be improved to the efficiency of fume treatment in body 1.
Specifically, the right side lower end on the absorption tower 11 is equipped with sewage pipe 12, and blowdown valve is installed on sewage pipe 12,
Drop and dust discharge that sewage pipe 12 facilitates discharge absorb the bottom of the tower are set.
Specifically, the top of the cylinder 1 is equipped with baffle 3, and baffle 3 and smoke backflow pipe 8 are socketed, and baffle 3 is arranged,
Prevent the flue gas entered in untreated preceding reflux.
Specifically, flue gas is by tube bank top periphery gas inlet 4 tangentially even into cylinder 1.
Tube bank rotation remittance gas-liquid-solid multiphase separator is that air-flow is rotated in cylinder 1 and is added without Secondary Air centrifugal
Dedusting demister.It is to generate centrifugal force to dust and droplet using swirling eddy, separates it in gas, separation
Minimum grain size can reach 5-10 μm.
Working principle: in use, 40 DEG C of -80 DEG C of flue gases are flowed into the inside on absorption tower 11 from air inlet 13, pass through cylinder
1 upper tangential hole uniformly flows into each cylinder 1, and overall flow should be maintained at 5m/s-8m/s.Gas inlet flow velocity is lower, contains
Air-flow will become circular motion from linear motion when the gas of dirt and droplet enters separator from tangential admission mouth.Swirling eddy
The overwhelming majority is helically downward from cylinder along wall, flows towards centrum.Dust-laden and droplet gas generated in rotary course from
Relative density is greater than the particulate matter of gas and drop is got rid of to wall by mental and physical efforts.Grit and droplet will lose once contacting with wall
Radial inertial force and by the lower momentum of row and downward gravity along wall surface whereabouts, into discharge outlet, reach separating effect.
When the outward turning gas of rotation decline reaches centrum, drawn close due to the expansion of cone to the wall of dedusting demister.
According to ' spin moment ' invariance principle, gas flow space becomes smaller, and tangential velocity is continuously improved, axial suffered by particulate matter and droplet
Motive force is also constantly reinforced.When a certain position in air-flow arrival centrum lower end, i.e., is converged and divided from tube bank rotation with same direction of rotation
From device middle part, by lower counter steer, continuing the flowing of spinning property and interior rotational airflow.Final purification gas is through exhaust pipe discharge pipe
Outside, thus the particulate matter of a part of collection at large and droplet are also discharged, pass through the rotation of the second level of first order flabellum 5 and 7 flabellum
Higher flow rate is obtained, to realize in the abjection and separation different in flow rate to flue fog drip and particulate matter.The higher generation of flow velocity
Centrifugal force is bigger, and it is better to separate to the multiphases substance such as gas, liquid, solid.But flow velocity is too fast, can be by separated droplet and particulate matter
It directly blows away and takes flue (and secondary dirt, reentrainment) out of, demisting dust-laying effect weakens significantly at this time, this flow velocity is critical flow
Speed must not exceed critical flow velocity in design.At 20 microns or more, removal rate 99% is protected for general droplet and particle size
Dedusting defogging effect is demonstrate,proved, and is equipped with Flushing nozzle 6, interval is sprayed water, and after shunting by centrum 2 to water, passes through 1 lower end of cylinder
Discharge outlet 16 drop collected and dust are flushed to the bottom on absorption tower 11, be discharged by sewage pipe 12, dedusting demisting
Flue gas afterwards is discharged by smoke backflow pipe 8 to the gas outlet at the top of absorption tower.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
