Eddy flow bubbling restrains dedusting section operation principle：Pending flue gas tangentially enters one cyclonic room from smoke inlet 12,
The water smoke that the top spray head 8 of smoke inlet 12 is sprayed at the shower nozzle can moisten flue gas in dust, dust is by water in this process
Mist moistening makes its weight increase and be advantageous to be separated.Afterwards, flue gas initially enters two level cyclone chamber, is dispersed into single rotation
In air duct 9, i.e., into the annular space between cyclone cylinder 9 and cyclone blade 11, cyclone blade 11 makes gas be become by linear motion
For circular motion, single swirling eddy is formed, the overwhelming majority of swirling eddy is twist downward along the inwall of cyclone cylinder 9, towards tower
The water surface impact flow of 1 bottom cistern of body 5；Dusty gas produces centrifugal force in rotary course simultaneously, and density is more than into gas
Grit get rid of to barrel.Grit contacts with barrel, just loses inertia force and leans on the momentum of entrance velocity and downward gravity edge
Wall drops downward into the bottom water surface of tower body 1.When the outer rotational gas flow that rotation declines reaches 4 cylinder lower end position of central tube, produce the bottom of to
The impact of portion's water surface, skimmed at a relatively high speed from the narrow gap of the bottom of central tube 4 and water.Due to flue gas high-speed motion, swash
Play spray and form water droplet and foam, the grit remained in flue gas by water droplet, foam adhesion and in the water that drops, flue gas is from central tube
In 4 upwards, discharged by exhaust opening 2.
Spray desulfurization section operation principle：The flue gas for continuing to rise along central tube enters the flue gas even distribution plate in tower body stage casing,
In the presence of flue gas even distribution plate so that flue gas uniformly rises in tower body, and good reaction condition is created to spray desulfurization.Uniformly
The flue gas of rising sequentially passes through the high density spray washing reaction zone of two-stage spray equipment formation and absorbing reaction area, doctor solution lead to
It is that flue gas and being sufficiently mixed for doctor solution provide huge contact area to cross spiral nozzle and generate superfine droplet so that gas-liquid
Two-phase carries out sufficient mass transfer and the physical-chemical reaction of heat transfer, and SO2 is absorbed in droplet descent and catches profit grit, from
And reaching SO2 efficient removal, the grit of moistening flows downwardly into tower body bottom, and sedimentation basin is discharged into from drainpipe.
Turbulent flow dust-removal and desulfurizing section operation principle：Continue to rise through spray desulfurization section flue gas, into turbulent flow dust-removal and desulfurizing section,
Entrainment of substantial amounts of vapor and a number of dust in flue gas, the small-sized of multiple ventilation ducts formation is entered in uphill process
Passage, the interior effect by tilting pod apertures on deflector of passage forms small-sized vortex chamber, and top is full of dedusting spheroid, dedusting
Spherome surface forms liquid film, dust and liquid film contact and is captured, and aggregation, flue gas and dedusting spheroid hair are produced on dedusting spheroid
After the effects such as raw inertial collision, adhesion, aggegation, dust and water is set to be separated with gas by sedimentation theory.As flue gas presss from both sides
The water vapour of band is constantly added, and the dust of dedusting spherome surface attachment is rinsed, constantly updates the liquid film of spherome surface,
The water droplet of dust is carried secretly from bottom of towe cistern on dedusting spheroid.So circulation, finally realizes depth dedusting function.
Doctor solution in the flue gas risen in bubble type dedusting and desulfurizing tower entrainment of certain ingredients is broken down into multiple small-sized
Passage enters turbulence device, and the flue gas driving vortex chamber interior spheroid of rising rotates, and the flue gas passed through can be produced scattered and again
The effect of gas field is integrated, significantly increases gas liquid interfacial area and time, so that turbulence device forms secondary desulfuration device
（Spray is considered as once desulfurization）, thus improve desulfuration efficiency.
Compared to static deflection plate demister, low power consuming, high-effective dust-removing desulfurization turbulence device have self-cleaning function.Work as ash
When dirt is adhered to spherome surface, it can be slid because of continuous motion collision, the phase mutual friction of spheroid, so as to thoroughly prevent tradition
The easy fouling of demister, susceptible to plugging problem.
Last clean flue gas is drawn by arranging bead, completes whole dust-removal and desulfurizing program.
Dust-laden waste liquid is discharged into sedimentation basin by cylinder body bottom drainpipe,（Drainpipe has water seal design to prevent gas leakage, and is provided with
Cleaning eye is convenient for cylinder body bottom cleaning）Through precipitation（Ash disposal）And add alkali（Regeneration）Posterior circle uses.
