The specific embodiment
As shown in Figure 1; The utility model comprises inlet plenum 1, tower body 2, exhaust outlet 3, is disposed with pneumatic part flow arrangement 21 in the tower body 2 from the bottom up, carries in the cover tower in spray equipment 22, the second cover tower spray equipment 24 and dehydrating demisting device 25 in spray equipment 23, the 3rd cover tower.The bulky grain flue gas under the air-introduced machine effect by smoke inlet 12 inlet plenums 1; This moment, flue gas had certain pressure ability, and indoor spray equipment 11 is set on the top of inlet plenum 1, and flue gas is by the absorption liquid humidifying of indoor spray equipment 11 ejections; This moment, the temperature of flue gas descended; The speed of flue gas stream also reduces, and the impact that the absorption liquid that sprays from indoor spray equipment simultaneously passes through flue gas stream is atomized into littler water particle, makes gas-liquid two-phase mix more fully; Thereby make that the bulky grain flue dust is captured effectively, i.e. SO in the flue gas
2And flue dust has obtained certain absorption at this.Because the direction of inlet plenum 1 is oblique following, flue gas is that rotation is risen when inlet plenum comes out to get into tower body.
As shown in Figure 2; Pneumatic part flow arrangement 21 is made up of the sheet metal 212 that newel 211 and multi-disc are shaped as isosceles trapezoid, and an end of sheet metal 212 is welded on the newel 211 through connector, and the other end is fixed on the inwall of tower body 2 through connector; Sheet metal 212 has certain included angle with horizontal direction; This angle confirms that according to the parameter of flue gas stream scope is spent between 30 degree 22, and the ventilation rate of the circumference that whole sheet metal 212 surrounds is about 40%.When the flue gas that comes out from inlet plenum 1 stream during through this pneumatic part flow arrangement 21; Flue gas stream is passed from a plurality of narrow and small preset passages; Its rotation rate of climb is further strengthened; The energy of flue gas stream increases widely, and whole flue gas stream is mixed evenly, that is to say that this pneumatic part flow arrangement 21 has the function of stirring.
As shown in Figure 1; Flue gas stream is through behind the pneumatic part flow arrangement 21; For gathering high-octane rotation ascending air is arranged; Hold and shred in the cover tower of top first in spray equipment 22, the second cover tower in the spray equipment 23 and the 3rd cover tower the absorption liquid of ejection the spray equipment 24, make the absorption liquid drop become absorption, the extremely strong small globule of trapping ability.These small globules are in contact with one another collision with flue gas that fast rotational rises in tower body 2, absorption, capture flue dust, dissolving absorbs SO
2, owing to collision, absorption, capture, globule diameter constantly increases, and decentralization reduces, and is thrown toward the tower wall, and in the collecting tank 26 at the bottom of under the gravity effect, flowing to tower, the sewage draining exit 4 by collecting tank 26 bottoms directly is discharged in sedimentation basin or the concentration basin then.
As shown in Figure 6; When flue gas after being purified is flowed through dehydrating demisting device 25 with certain speed; Contain a large amount of mists in the flue gas; Because the inertial impaction effect of gas; Mist and many bendings corrugated sheet 251 collide and are attached on its surface, and the gravitational settling that diffusion, the mist of mists are gone up in many bendings corrugated sheet 215 surface makes mist form bigger drop and with the air-flow turning of bending corrugated sheet 251 at the most that travels forward, owing to turn to centrifugal force and make drop increasing with the surface tension of rubbing action, suction-operated and the liquid of many bendings corrugated sheet 251; Up to the drop that gathers arrive greatly climbing power that the gravity that himself produces surpasses flue gas and surface tension of liquid with joint efforts the time, drop is just separated from corrugated sheet.The structure that is folded to of many bendings corrugated sheet 251 of dehydrating demisting device 25 has increased the chance that mist is collected more; The mist that is not removed is collected through identical effect at next turning, effect so repeatedly, thus improved demist efficient greatly; So flue gas is through behind the dehydrating demisting device 25; Be substantially free of mist, discharge, introduce smoke stack emission in atmosphere by air-introduced machine then from the exhaust outlet 3 at tower body top.
Because be wrapped in the dust granule in the flue gas in the mist; So can gather dust on many bendings corrugated sheet 251 of dehydrating demisting device 25, the time has been grown the flow velocity that will influence flue gas, also will increase the resistance of entire equipment; Dehydrating demisting device 25 comprises 3 cover back purge systems 252; One cover back purge system (252) respectively is set in the upper and lower both sides of lower floor's many bendings corrugated plating (251), the nozzle of downside up, the nozzle of upside is down; Also have a cover back purge system (252) to be installed in the below of many bendings of upper strata corrugated plating (251), nozzle up.Set backwashing time and gap according to pressure display, the resistance that guarantees entire equipment is in design load.
