Description

A kind of metal plate type wet dust removal defogging equipment
Technical field
The utility model is related to a kind of dedusting demister, more particularly to a kind of metal plate type wet dust removal defogging equipment, Belong to technical field of environment protection equipment.
Background technology
In recent years, with the continuous development of industry, cause China's atmosphere pollution increasingly serious, the flue gas particularly in air Pollution, causes haze weather in recent years serious, endangers the healthy of the mankind.How to contain the discharge of flue gas pollutant into One of matter of utmost importance for current industrial development, in view of environmental protection standard is gradually strict, to major pollutants index ultralow row is implemented Put standard, it is desirable to the discharge index≤5mg/Nm of dirt.So promote to the application of deduster in industrial production, and then lifted Further investigation to electric cleaner.
The cleaning principle of electric cleaner is:Using the strong electric field formed between negative electrode and anode, make air molecule electric From a large amount of electronics of moment generation, negative ions make the particulates such as the dust and droplet by electric field charged, in the effect of electric field force It is lower to do directed movement to negative electrode, anode, the particulates such as dust and droplet is gathered on negative electrode, anode, to realize to discharge Flue gas carries out purified treatment.
Coal fired power plant, for the improvement of dirt, is at present that big dust particle is removed before desulphurization system using more method, Final dusting is carried out by the demister of desulphurization system, dedusting index is up to 15 ~ 30mg/Nm.Reach after to make desulphurization system The emission request of dust≤5mg/Nm, existing wet dust removal defogging equipment has two kinds, and one kind is outer horizontally disposed in desulfurizing tower Metal plate type wet scrubber, it is a kind of be outside tower top or tower arrange nonmetallic pipe precipitator.But this two kinds of equipment are equal There is certain defect.
For horizontally disposed metal plate type wet scrubber, cyclic water tank, discharge casing, water supply tank, plus alkali tank need to be equipped with (Adjust circulating water PH value)And a series of water system equipment such as various pumps, carry out continuous moisture film to pole plate in operation and rinse anti- Only pole plate corrosion, because water consumption is big, is not suitable for the serious coal fired power plant of water shortage and uses, and operating cost is higher.Simultaneously this kind sets Standby to be arranged in outside tower, floor space is larger, is not suitable for lacking the transformation project of the Built hydropower station in place.
For the nonmetallic pipe precipitator arranged outside tower top or tower, because anode tube bank electroconductive frp is adopted more, had Stronger antiacid corrosive power, it is not necessary to rinsed using continuous moisture film as plate-type dedusting device, it is only necessary to using interrupted, interval spray Water is rinsed, and water system is simple.It is careless slightly in installation or running but electroconductive frp belongs to inflammable thing, will occur There are a lot of such accidents in pyrophoricity accident, the country, suffer heavy losses;The electroconductive frp tube bank that in addition anode is adopted simply exists The inner surface of tube bank has inlayed one layer of conductive fiber felt, and its electric conductivity is passed through again at a high speed far away from metallic anode plate in operation , there is the possibility of conductive fiber layer peeling in washing away for flue gas.Domestic coal fired power plant minimum discharge project it is newly-built or transformation in adopt Pipe precipitator operation the time limit it is shorter, above-mentioned latent defect does not also expose, such as defect occur, the maintenance or replacing of equipment Will be extremely complex.
