Description
Technical field
This utility model is related to wet-esp apparatus field, more particularly, to a kind of simple wet electric dust collector.
Background technology
The equipment that dust is separated from flue gas is cleaner unit or cleaner.The performance of cleaner unit is with accessible
Gas flow, gas are expressed by drag losses during cleaner unit and efficiency of dust collection.Meanwhile, the price of cleaner unit, operation and dimension
The difficulty or ease of shield expense, service life length and operation management are also the key factor considering its performance.Cleaner unit is boiler and work
The conventional facility in producing of industry.
Cleaner unit is divided into according to dedusting method: dry collector, half dry type cleaner unit and wet scrubber.
Wet electrical dust precipitator be a kind of for processing the new cleaner containing micro dust and microparticle, be mainly used to remove
Containing harmful substances such as the dirt in humid gas, acid mist, water droplet, aerosol, stink, pm2.5, it is the ideal administering atmospheric dust pollution
Equipment.
Wet electrical dust precipitator washes away dust collecting electrode surface to carry out deashing using liquid, can effectively collect fine particle
(pm2.5 dust, so3 acid mist, aerosol), heavy metal (hg, as, se, pb, cr), organic pollution (polycyclic aromatic hydrocarbon, two English)
Deng.Using the soot emissions containing after wet electrical dust precipitator in wet flue gas up to 10mg/m3 or even below 5mg/m3, dust collection performance with
Dust Characteristics unrelated it is adaptable to containing wet flue gas process, the place of especially suitable ash-laden gas after power plant, steel mill's wet desulphurization
In reason, but equipment investment is costly, and need to support the use with other cleaners, its investment technology economy and operating cost
To be evaluated from overall.
Wet electrical dust precipitator has several versions, and one kind is (can be excellent for electric conductivity using corrosion-resistant conductive material
Good nonmetallic materials or the metal material with corrosion resistance characteristic) do dust collecting electrode, one kind is with by water spray or overflow water
Form the conductive nonconducting nonmetallic materials of moisture film and do dust collecting electrode.
Wet electrical dust precipitator also can be divided into cross-flow type (horizontal) and vertical-flow (vertical), and cross-flow type mostly is plank frame, gas
Direction of flow passes in and out for horizontal direction, and structure is similar to dry electric precipitation device；Vertical-flow mostly tubular structure, gas flow is Vertical Square
To turnover.In general, in the case of equal ventilation sectional area, vertical-flow wet electrical dust precipitator efficiency is 2 times of cross-flow type.
Dust on pole plate for the heavy collection can be rinsed by water.Wet type deashing can avoid having trapped dust
Fly upward again, reach very high efficiency of dust collection.Because of no rapping apparatus, run also relatively reliable.Made using modes such as water spray or overflow waters
The device of dust collecting electrode surface formation conducting film has the process problem of burn into mud and sewage, only in gas dust content relatively
Low, just adopt when requiring dust-laden efficiency higher；Do not need to grow using the wet electrical dust precipitator that corrosion-resistant conductive material does dust collecting electrode
Phase water spray or overflow water, are only periodically rinsed according to system operation situation, only consume minimal amount of water, this part water is recyclable
Recycle, the basic non-secondary pollution of dust collecting system.
