Comparing and have the following advantages, simple in construction, builds and operating cost is low.
With specific embodiment, the technical solution of the utility model is carried out in detail below in conjunction with the accompanying drawings
Explanation.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model desulfurization demister system；
Fig. 2 is the structural representation of pallet in this utility model desulfurization demister system
In figure: 1, demister, 2, gas approach, 3, exhanst gas outlet, 4, spray thrower, 5,
Electrostatic precipitator, 6, water tank, 7, electrostatic precipitator, 8, pallet, 9, Ball-type packing
Detailed description of the invention
A kind of desulfurization demister system, including demister 1, described demister bottom has cigarette
Gas import 2, top has exhanst gas outlet 3, and described demister top is provided with at least one of which spray
Device 4, described spray thrower is arranged over electrostatic precipitator 5, and described electrostatic precipitator includes corona wire
And collecting polar plate, it being provided with water tank 6 below described gas approach 2, described spray thrower 4 enters with flue gas
Being provided with pallet 8 between mouth 2, described pallet is the sieve plate of horizontal, is provided above with at this sieve plate
Ball-type packing 9.
Further, the upstream of described gas approach arranges electrostatic precipitator 7, and it is by horizontal dust
Room forms with grooved pole plate.
Further, described Ball-type packing 9 is plastic filler ball.
Further, arrange below described spray thrower and be made up of the most horizontally arranged gusset
Uniform flow grid, these uniform flow grid can arrange multilamellar, and the gusset position of each adjacent layer is staggeredly arranged.Institute
Stating the flue gas stream that uniform flow grid have entering in demister to homogenize, strengthening spray removes further
Dirt, the effect of desulphurization and denitration.
The operation principle of this utility model desulfurization demister system is as follows:
During work, the electrostatic precipitator 7 that flue gas is arranged through gas approach 2 upstream enters except mist
Device 1.Described electrostatic precipitator 7 uses software feature quasi-steady DC source as dust arrester
Power supply, by coordinating of horizontal dust storage chamber and grooved pole plate, forms efficient electrostatic precipitation
Device, its efficiency of dust collection is up to more than 90%.Flue gas after dedusting is from demister 1 bottom
Gas approach 2 enters demister 1.The spray thrower 4 that this demister 1 top is arranged sprays mist
The Ozone Water changed, sprays the flue gas entering from gas approach and ramping up, spray
Ozone Water and do not dissolve in the ozone gas in water and the nitric oxide chemically reactive in flue gas
Generation falls into after being dissolved in the higher nitrogen oxides of water in the water tank 6 arranged below gas approach, cigarette
Sulfur dioxide in gas becomes sulfur trioxide with ozonisation symphysis, then combines generation sulfur with ozone water mist
Also fall in water tank 6 after acid and sulfate.Arrange between described spray thrower 4 and gas approach 2
Having pallet 8, described pallet is the sieve plate of horizontal, is provided above with Ball-type packing 9 at this sieve plate.
The pressure drop that pallet produces further promotes the uniformity of smoke distribution, for spray thrower scrubbing section
Gas-liquid uniform contact provides the best guarantee.Uniform flow can be set below described spray thrower
Grid, homogenize the flue gas stream entered in demister, play strengthen further spraying and dedusting,
The effect of desulphurization and denitration.Flue gas after spray cleaning enters electrostatic precipitator.Described quiet
Electrostatic precipitator is to utilize high direct voltage electric forming high pressure non-uniform electric field to produce corona discharge, makes gas
Volume ionization, causes the grit being dispersed in gas and acid mist and negative ion to meet and charged.?
Under electric field force effect, shift to receiving electrode, thus reach to purify the purpose of gas.Through above-mentioned place
The flue gas after the reason exhanst gas outlet from demister top is discharged.
The above is only preferred implementation of the present utility model, it is noted that for this skill
The those of ordinary skill in art field is can some changes in addition without departing from scope of the present utility model
Change, therefore the structure shown in described above comprised and accompanying drawing should be regarded as exemplary, rather than use
To limit the protection domain of this utility model patent.
