On direction be connected, independently of one another, setting spiral rises streamlined shaped spiral housing 45 purpose be in order to extend flue gas stroke, increase
Gas-liquid contact time, strengthens the ability of trapping dust, in consideration of it, being respectively provided with atomizer 15, mist above each rotating channel
Change 15 connecting leg roads of shower nozzle through the wallboard of each rotating channel, seam is sealed.Ash-laden gas and foam solution are in Wen Qiu
In be sufficiently mixed in premixed device 4 after enter in trunnion 33, produce Venturi effect and improve after kinetic energy that at a high speed rotation rises, diameter 10
There is moistening, collision, reunion, sinking in dust more than μm, Jing bottoms orifice plate 54 enters grey hydroecium 5, dust in purified gas
Diameter is below 10 μm.In order to remove less than 10 μm of dust, charged droplet, droplet and powder are sprayed above rotating channel
Dirt is fully contacted, and as air-flow constantly disturbs advance, is finally discharged into settling deentrainment tower 8 by anemostat 14, because sedimentation is removed
It is tridimensional structure in mist tower 8, high velocity air enters into flow velocity in the space of large volume and rapidly reduces, weight after droplet adsorption of dust
Increase, volume increase as the reduction of air velocity can gradually sink down into bottom, and then is discharged by bottom leakage fluid dram 49.Letter
For it, atomizer and flue gas directly contact, the droplet of so ejection can be sufficiently mixed with flue gas, so just can occur
The phenomenons such as absorption, reunion, coalescence, play a part of to trap dust.
The present invention realizes coalescence, reunion, the collection of dust by adding particular solution using classification dedusting, it is possible to achieve
Simultaneously desulfurization and dedusting, simple structure is easy to operate, and floor space is less, and reduced investment, operating cost is low, specific as follows：1st, at present
Traditional dust removal installation volume is larger, single function, and the present invention is single column arrangement, processes 200,000 m3The flue gas of/h, tower body diameter
For 4.5m, same tolerance needs 6.5m using wet-esp diameter, remaining affiliated facility can with treatment in accordance with local conditions, flexible arrangement,
Do not limited by place；2nd, present invention investment saves 30% compared with wet-esp, and operating cost is low by 20%；3rd, the present invention can basis
Different emission requests automatically control added solution, simple to operate, it is not necessary to carry out the adjustment of complexity, load adaptability is good, can be with
Continuous operation, wet-esp needs to have a power failure and rinses, and outage equipment does not work, and outer row's dust is in exceeded state, exists
Environmentally friendly risk；4th, energy-conserving and environment-protective of the present invention, waste water can be recycled, and the wet ash of collection can send into boiler combustion, without waste residue
Produce；5th, in addition the present invention can have desulfurizing function concurrently, realize desulfurization and dedusting simultaneously, reach minimum discharge.
For the more detailed explanation present invention, the present invention is further elaborated in conjunction with embodiment.Specific embodiment
