Contained dust, sulphur and nitrogen oxide are all the substances for polluting atmosphere in boiler smoke, it is discharged when not purified
Index is likely to be breached several times of pollution control regulation index to decades of times.The measure for controlling the discharge of these substances has place before burning
Reason, improvement combustion technology, dedusting, desulfurization and denitration etc..
In dust removal process, boiler electrostatic precipitator and cloth envelop collector efficiency of dust collection with higher.Wet electrical dust precipitator
Flying dust can be adhered to water droplet moisture film in Wen-water dust scrubber, efficiency of dust collection is very high, moreover it is possible to absorb gaseous pollutant, such as sulphur and
Nitrogen oxide.Therefore, the dust-extraction unit of better dust removal effect in the prior art when wet electrical dust precipitator.
After the boiler smoke wet desulphurization of power plant in ash-laden gas, smoke moisture is big, is handled using wet electrical dust precipitator
Flue gas can effectively collect fine particle (PM2.5 dust, SO3 acid mist, aerosol), heavy metal (Hg, As, Se, Pb, Cr), have
Machine pollutant (polycyclic aromatic hydrocarbon, dioxin) etc., containing the soot emissions in wet flue gas up to 10mg/m even 5mg/m or less.
Wet electrical dust precipitator has the following problems when in use in the prior art：1, a large amount of due to existing in boiler smoke
Sulphur and nitrogen oxide, such as sulfur dioxide, sulfur trioxide, nitrogen dioxide, after being handled even by desulphurization denitration, in flue gas
Still there is sulphur and nitrogen oxide, sulphur and nitrogen oxide meet the aquatic sour water for producing and having highly acid, easily erosion wet type electricity
The internal structure of deduster has seriously affected service life and the dust removing effects of wet electrical dust precipitator；2, since wet electrical dust precipitator needs
Use water spray, and existing water sprinkler system, by the way of direct current, shower water the dedusting indoor residence time compared with
It is short, and the discharge rate of sewage is larger, not only causes the waste of water resource, while the treatment and purification of sewage is caused again at new waste water
Reason problem；3, in boiler smoke there are organic pollutant, such as polycyclic aromatic hydrocarbon, dioxin, when using wet electrical dust precipitator dedusting,
It can be discharged by shower water effectively by Adsorption of Organic, still, equally cause waste water handling problem；4, due to electricity
After the boiler smoke wet desulphurization of factory in ash-laden gas, smoke moisture is big, and vapor wraps up dust, forms macromolecular particle,
The corona effectively generated by electrode is difficult to adsorb；It is difficult to remove the aqueous dust of macromolecular using wet electrical dust precipitator dedusting.
Therefore, it is badly in need of a kind of novel boiler smoke wet electrical dust precipitator, the effective solution above problem.
Summary of the invention
To solve the above problems, the invention discloses a kind of boiler of power plant flue gas wet electrical dust precipitators, water is effectively used
The circulatory system improves efficiency of dust collection, and reduces wastewater treatment, preferably protects environment, saves water；On the other hand, the wet type
Electric precipitator reduces absorption of the vapor to dust in flue gas, good dedusting effect, effective dedusting.
In order to reach the goals above, the present invention provides the following technical solutions：
A kind of boiler of power plant flue gas wet electrical dust precipitator, including dedusting shell, support base, insulator chamber, the dedusting shell

System；The fixed card of several electric discharge cathode lines, several dust anode tubes, cathode hanger pipe, anode is equipped in the dirt pocket；It is described
Electric discharge cathode line excircle set is equipped with dust anode tube；The electric discharge cathode line connects the height by cathode hanger pipe and presses
Electric installation；The electric discharge cathode line lower end is equipped with anti-pendulum；The cathode hanger pipe is fixed at the locular wall top of dirt pocket,
The fixed card of the anode is fixed at the locular wall lower part of dirt pocket, and the plate face of the fixed card of the anode is equipped with several logical
The lower section in hole, the fixed card of the anode is equipped with ash bucket, and the ash bucket connects water circulation system；The water circulation system includes collection
Waterpipe, settling tank, water pump, circulation conveying pipeline；The gray water outlet of the ash bucket connects collecting conduit, and the collecting conduit connects
Connect settling tank；The settling tank connects circulation conveying pipeline by water pump, and the circulation conveying pipeline connects spray tube.
Preferably, the roof of the settling tank is equipped with ultraviolet lamp tube, the pool wall of the settling tank is equipped with titanium dioxide
The bottom of photocatalytic plate, the settling tank is equipped with L-type buffer board, and the L-type buffer board includes transverse slat and riser, the cross
Plate is fixedly connected on the pool wall of settling tank, and the transverse slat is sealing transverse slat, and the riser is waffle slab；It is set below the transverse slat
Active charcoal adsorption layer.Using the setting of ultraviolet lamp tube and photocatalytic plate, it can be achieved that (such as polycyclic to the organic pollutant in buck
Aromatic hydrocarbons, dioxin etc.) photocatalysis, the effective organic matter purified in buck, and realize free of contamination processing is organic after processing
Pollutant purification is at carbon dioxide, water, without other pollutants, treated buck, clarification free from admixture, it can be achieved that buck circulation
