Foam solution addition, thus controls foam measuring pump frequency converter 35 and diluting water regulating valve 37, makes to enter venturi premixed device 4
Foam solution total flow in 10.5~11.5m3/h；
Step 2：Ash-laden gas and foam solution enter in trunnion 33 after being sufficiently mixed in venturi premixed device 4, produce
Venturi effect, which is improved, rotates at a high speed rising after kinetic energy, wetting, collision, reunion, sinking occur for more than 10 μm dust of diameter, the bottom of through
Portion's orifice plate 54 is discharged into dust diameter in grey hydroecium 5, purified gas and below 10 μm, streamlined propeller cap is risen by spiraling
Body 45 and exit cone 14 enter in sedimentation deentrainment tower 8, and chimney 7 is discharged into after further reunite sedimentation and demisting；
Step 3：When outer smoke evacuation dust concentration detector 39 detects row concentration ＞ 10mg/Nm out3When, pass through what is detected
The flue gas flow of outer row's dust concentration and step one detection, the control surface activating agent measuring pump frequency converter 23 of controller 52 and spray
Water regulating valve 21, makes total fluid flow into electrostatic generator in 5.2~5.5m3/ h, powered shower water is through high-efficient atomizing
Atomizer 15 is produced and dust size identical droplet, for adsorption of dust；
Step 4: the sedimentation bottom buck of deentrainment tower 8 passes through the first leakage fluid dram 49 and the second discharge opeing respectively with the grey buck of hydroecium 5
Mouth 50 is imported in circulating water pools 26, is extracted out and is used for system circulation by water circulating pump 31 after precipitation and separation, recirculated water densitometer
28 detect circulation water density ＞ 1060kg/m3, controller 52 control the bottom blow-down regulating valve 27 of circulating water pool 26 open, liquid level
Meter 29 detects the liquid level in circulating water pool 26, when liquid level declines ＜ 2.8m, and the control moisturizing of controller 52 regulating valve 25 is opened, and is opened
Beginning moisturizing, when recirculated water densitometer 28 detects circulation water density≤1040kg/m3When, the control circulating water pool 26 of controller 52 bottom
Portion's sewage discharging regulation valve 27 is closed, and when the liquid level that liquid level gauge 29 is detected in circulating water pool 26 rises to 3.2m, controller 52 is controlled
Moisturizing regulating valve 25 is closed；
Step 5：Controller 52 detects the outlet of lower floor's demister 13 second pressure detector 9 and shows pressure ＜ 250Pa
When, opening the second flushing water motor-driven valve 53 makes lower floor's flushing pipe 44 be rinsed lower floor's demister 13；Controller 52 is detected
When showing pressure ＞ 350Pa to the outlet of lower floor's demister 13 second pressure detector 9, the second flushing water motor-driven valve 53 is closed；
Step 6：Controller 52 detects the outlet of upper strata demister 43 first pressure detector 12 and shows pressure ＜ 100Pa
When, opening the first flushing water motor-driven valve 11 makes upper strata flushing pipe 10 be rinsed upper strata demister 43；Controller 52 is detected
When showing pressure ＞ 200Pa to the outlet of upper strata demister 43 first pressure detector 12, the first flushing water motor-driven valve 11 is closed.
It should be noted that：" atomizer of the powered shower water through high-efficient atomizing described in the step of above-mentioned technique three
15 produce and dust size identical droplet, for adsorption of dust；" can with dust size identical droplet by powered spray
Adsorption efficiency is effectively improved, research shows, particle diameter identical droplet is easier to combine with dust, is easy to trapping；If particle diameter phase
Difference is larger, dust escape is easily caused, so as to cause dust removing effects to be deteriorated.In addition, pressure-measuring-point is in lower floor's demisting in step 5
The top of device 13 is set, and pressure is certain value during normal operation, when there is pressure reduction, illustrates that lower floor's demister 13 circulates not
Freely, dust accumulation causes flow area to reduce, and at this time needs to start spray, conversely, pressure rise, illustrates lower floor's demister 13
Circulation is smooth, and upper strata demister 43 is begun to block up.
The utility model is according to dust size size, charge characteristic, using labyrinth type swirl-flow devices, additional foam solution warp
Venturi premixed device 4 is intercepted to dust, adhered to, moistened, and applying surface activating agent makes spray by electrostatic generator 17
Water produces charge effect, and distributing Electrostatic Absorption, sedimentation are realized in labyrinth type swirl-flow devices and sedimentation deentrainment tower 8.According to useless
The emitted dose of the powered shower water of size Intelligent adjustment of dust emission concentration and injection concentration, the gravity produced by eddy flow in gas
Field accelerates adsorption process, promotes dust granules to reunite, sinks, collects, so as to realize the effect of dedusting, is further sunk by top
Drop and demisting, purified gas can reach minimum discharge standard.Meanwhile, addition desulfurizing agent can also be realized in circulation fluid
The purpose of scrubbing CO_2.
Described several described in the utility model streamlined shaped spiral housing 45 of rising that spirals is not connected mutually, atomizer
15 are separately positioned on to spiral and rise the internal upper part of streamlined shaped spiral housing 45；Each streamlined shaped spiral housing 45 of rising that spirals only exists
On flow direction be connected, independently of one another, set spiral rise streamlined shaped spiral housing 45 purpose be in order to extend flue gas stroke,
Increase gas-liquid contact time, the ability of enhancing trapping dust, in consideration of it, being respectively provided with atomizer above each rotating channel
15,15 connecting leg roads of atomizer pass through the wallboard of each rotating channel, and interface is sealed.Ash-laden gas and foam solution exist
Enter after being sufficiently mixed in venturi premixed device 4 in trunnion 33, produce Venturi effect and improve rotation rising at a high speed after kinetic energy, directly
More than 10 μm of footpath dust occurs wetting, collision, reunites, sinks, and is discharged into through bottom orifice plate 54 in grey hydroecium 5, purified gas
Dust diameter is below 10 μm.In order to remove less than 10 μm of dust, electrically charged droplet, droplet are sprayed above rotating channel
Fully contacted with dust, as air-flow constantly disturbs advance, sedimentation deentrainment tower 8 is finally discharged into by anemostat 14, due to heavy
It is tridimensional structure to drop in deentrainment tower 8, and high velocity air enters flow velocity in the space of large volume and rapidly reduced, after droplet adsorption of dust
Weight increase, volume increase, as the reduction of air velocity can gradually sink down into bottom, and then passes through the row of bottom leakage fluid dram 49
