Technical field
It is molten that the utility model is related to cooperation-removal flue dust, drop and gas in filed of flue gas purification, particularly desulfuration absorbing tower
The Wet type electric dust-removing device of the pollutants such as glue, fine particle.
Background technology
The existing smoke gas treatment island technological process of China's coal-fired plant boiler afterbody is usually by denitration, deduster, wet method
Desulfurization etc. is constituted.However, during denitration device work, in the presence of catalyst, SO3 side reaction being converted into SO2, makes cigarette
SO3 contents in gas are greatly increased.The NH3 injected as denitrification reducing agent in flue gas, can produce part ammonia in actual motion
Escape.
For wet desulphurization, on the one hand, the partial particulate thing in flue gas can be removed by the cleaning function of desulfurization slurry；Separately
On the one hand, separated out due to there is desulfurization slurry atomization entrainment, desulfurization product crystallization, can also form fine particle.Desulfurizing tower is to SO3
Clearance it is very low, SO3 is discharged with flue gas in the form of an aerosol.Due to a large amount of SO3 presence, at the wet flue gas of chimney
Below acid dew point, its condensate liquid causes corrosion to chimney.Because existing wet desulfurization system removes the ability of fine particle very
It is weak, to mercury and SO3The removing of aerosol etc. is also limited, so as to cause the downstream of chimney wind direction " acid rain ", " gypsum often occur
The phenomenon such as rain ", " blue smoke ".
, it is necessary to there is equipment of checking on together again after wet desulphurization device, wet electrical dust precipitator is one and effectively solves way
Footpath.Wet electrical dust precipitator can remove more than 90% fine particle and SO3, mercury, NH can also be removed in addition3, drop etc..Therefore, it is wet
Formula electric cleaner is a kind of new selection of coal-burning power plant's tail gas terminal processes, the control of fine particle particularly in flue gas after desulfurization
System is a kind of effective measure, and providing one for coal-burning power plant had not only met minimum discharge requirement but also can control combined pollutant
Robust techniques.Wet-esp structure of the prior art generally has two kinds：One kind is integral type, and one kind is split type.It is existing
Uneven with the presence of integral type Wet type electric dust-removing device air flow method, electric discharge dead band is big, and material corrosion resistance is not good, exports drop
Carrying amount is big to wait not enough.
The content of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model, which is to provide one kind, can remove fine particle
Wet type electric dust-removing device.It can improve the uniformity of smoke distribution in tower, effectively save floor space, with electric discharge dead band
The characteristics of small, ash-removal effect is good.
In order to reach foregoing invention purpose, the technical solution of the utility model is realized as follows：
The Wet type electric dust-removing device of fine particle can be removed, it is placed in the top of spraying layer in absorption tower.Its design feature
It is that it includes airflow uniform distribution plate, wet electrical dust precipitator and rinse-system with independent housing successively from bottom to up.The air-flow
Uniform board uses wear resistant corrosion resistant material PP, thereon uniform multiple perforates, and percent opening is 50%.Hung down in the wet electrical dust precipitator
Straight many cathode lines of interlaced arrangement number and anode tube, anode tube use foamed glass steel construction.Supply water tank outside absorption tower
Rinse-system is connected to by supplying water pump.
In above-mentioned Wet type electric dust-removing device, the rinse-system uses interval backwashing manner.
In above-mentioned Wet type electric dust-removing device, cathode line uses titanium alloy material.
The utility model has advantages below and beneficial effect compared with the prior art：
1. ensure heat-engine plant desulfurized efficiency, it can be subtracted with impurity such as efficient removal fine particle, drop and aerosols
Film chimney corrodes, and solves the technical barriers such as " acid rain ", " gypsum rain ", " blue smoke ", reduces Pollutant emission concentration, reaches country most
New emission standard.
2. airflow uniform distribution plate takes the PP materials of wear resistant corrosion resistant, uniform pore openings are simultaneously staggered in arrangement, are designed with beneficial to air-flow
It is uniformly distributed, it is to avoid prior art air flow method is uneven, the problem of load adaptability is poor.
3. cathode line uses titanium alloy material, anode tube is foamed glass steel construction, with compact conformation, stress
Well, the characteristics of electric discharge dead band is small, material has excellent Anticorrosive Character.
4. wet-esp rinse-system rinses for interval, optimal deashing effect is at utmost reached while using water wisely
Really, reduction outlet drop carrying amount.
5. Wet type electric dust-removing device is located at desulfuration absorbing tower top, tower top vertical is taken, wet electrical dust precipitator has knot
Independent housing on structure, saves floor space, the power plant's upgrading for the insufficient space that is particularly suitable for use in.
The utility model is described further with reference to the accompanying drawings and detailed description.
