Description
Technical field
The present invention relates to a kind of coal-burning boiler desulphurization system more particularly to a kind of closed multilevel water curtains desulphurization systems.
Background technology
The flue dust that coal-burning boiler, stove discharge every year is up to more than 400,000,000 tons, and environment for the survival of mankind is made drastically to deteriorate,
The technology that desulfurization and dedusting is carried out to flue dust increasingly attracts attention.Currently, the method for flue gas desulfurization have dry type flue gas desulfurizing technique,
Spraying dry type flue gas desulfurizing technique, flyash dry type flue gas desulfurizing technology, wet fuel gas desulfurizing technology etc., wet process of FGD work
Skill flow, form and mechanism are similar, mainly use lime stone (CaCO3), quick lime (CaO) or sodium carbonate (Na2CO3)
Equal slurries make detergent, are washed to flue gas in reaction tower, to remove the SO2 in flue gas.This technique has 50 years
History, after continuously improving and improving, Technical comparing is ripe, has desulfuration efficiency high (90%~98%), unit holds
The advantages that amount is big, and coal adaptability is strong, and operating cost is relatively low and byproduct easily recycles.
In wet method mode, water curtain method desulfurization is a kind of widely used method, China Patent No.
ZL200820078306.9 discloses a kind of tower type water-curtain desulfurizing dust-removal device, in the water curtain cylinder and dehydration tube of this device up and down
It has been alternatively arranged multilevel water curtains cap and dehydration cap, sulfur-containing smoke gas and shower water containing desulfurizing agent can be made along water curtain cap and dehydration
The diffusion of cap is multi-level during pouring out to be come into full contact with, fuses, colliding, and greatly improves shower water to harmful in flue gas
Substance removes dynamics, can get ideal desulfurization and dedusting effect, but the water curtain cap of the present apparatus and dehydration cap are all concentrated and be laid in tower
The center of intracoelomic cavity, flue gas is not stopped effectively when being flowed along tower body internal chamber wall, therefore is reduced to this part cigarette
The molten water of dirt and the effect of dehydration, it is not too ideal that harmful substance, which still has the possibility of escape, desulfurization effect,.
China Patent No. CN201454328 U disclose a kind of tower type energy-saving high-efficiency desulfurizer, and the device is in water curtain cylinder
Barrel on be alternatively arranged multilayer polywater disk from top to bottom, be alternatively arranged from top to bottom on the barrel of dehydration tube multilayer dehydration
Plate, polywater disk and dewatering plate are annular, and outer edge closely connect with the barrel of water curtain cylinder, dehydration tube respectively, centre be flue gas and
Flow by circular hole, per strata water pond, the installation site of dewatering plate respectively in every layer of water curtain cap, be dehydrated the lower section of cap, the dress
It sets and increases polywater disk and dewatering plate in water curtain cylinder and dehydration tube, polywater disk and dewatering plate are laid along cylinder inboard wall, to along cylinder
The flue dust of wall flowing is effectively stopped, increases the contact area of flue dust molten water and dehydration, raising desulfurization effect, but water
The water curtain that curtain cap is formed directly is beaten on polywater disk, will directly be left, cannot be formed closely knit water curtain, and flue gas can still pass through,
Desulfurization is caused to be not thorough.
Equally, China Patent No. CN201454329 U disclose a kind of multilevel water curtains desulfurized dust collection column, although the device exists
Polywater disk is increased in tower, the flue dust flowed along barrel is effectively stopped, is increased the molten water of flue dust and is connect with what is be dehydrated
Contacting surface is accumulated, but the water curtain that water curtain cap is formed directly is beaten on polywater disk, will directly be left, cannot be formed closely knit water curtain,
Flue gas can still pass through, and desulfurization is caused to be not thorough.
Moreover, recently as the enhancing of environmental consciousness, China's environmental standard is continuously improved, industrial furnace and boiler air
The discharge of pollution performs stringenter standard, and existing desulfurizer is unable to reach new discharge standard, and desulfurization effect has
It waits further increasing.The discharge of sewage after desulfurization recycles and needs the major issue solved.

Amount, water overflow the water curtain that water fender 7 forms bigger.The flue gas that flows up and the flow to flow downward, water curtain, water mist meet and
Collision, during flowing and collision, water and flue gas are sufficiently mixed, the harmful substances such as sulphur in flue gas and devulcanizer
Reaction is learned, while sulphur is also dissolved in water, the impurity such as dust are also mixed with water, are dropped down with flow.By above-mentioned reaction and dissolving, molten
1 congregate of water tower cylinder of conjunction, and be discharged by sewage draining exit 8, the flue gas of desulfurization is encountered 1 internal upper part of tower and is set by 1 uplink of tower
The demister 17 set, after the processing of two layers of demister 17, flue gas is discharged by smoke outlet 3, achievees the purpose that desulfurization.Tower
After 1 work a period of time, opens clear water sparge pipe 19 and spray clear water, 1 cohesion water pond 6 of cleaning tower, water curtain cap 5,1 bottom of tower
Deng, it is ensured that sewage can all flow out and not in 1 bottom deposit of tower.The sewage being discharged by sewage draining exit 8 passes through sewage inlet
10 enter treatment tank 9, and the water-stop sheet 12 being arranged in treatment tank 9 ensures that sewage can be in treatment tank 9 fully
Precipitation, after the sewage purification of precipitation, is flowed out by water outlet, realizes recycling for sewage.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
