Description
Technical field
This utility model belongs to environmental protection technical field, and in particular to a kind of wet cottrell.
Background technology
Recent domestic environmental requirement more and more higher, various petrochemical industry tail gas, furnace flue gas must be reached after removing dust desulfurization
Mark discharge.At present, the technique of wet dedusting desulfurization is still a kind of reliable prevailing technology.However, wet dedusting conventional at present
The flue gas discharged after desulfurization process is higher containing wet, dust-laden and containing foam, emits white cigarette and conditions of streaking is serious.Emit white to reduce chimney
Cigarette and conditions of streaking, the flue gas after current wet dedusting desulfurization is processed are wanted Jing after electrostatic precipitator or wet cottrell are processed again
By smoke stack emission.
Electrostatic precipitator is a kind of dependence electrostatic force collecting the industrial equipment of above-mentioned dust.Its work includes as follows
Process：(1) high voltage from high voltage power supply is applied on corona wire, and corona wire produces corona discharge, and forms electric field；(2)
The dust in the flue gas of electric field is flowed through, the Ion Charged produced by corona discharge；(3) powered dust, under electric field force effect,
It is collected on dust collecting pole plate；(4) dust being collected on dust collecting pole plate, departs from from pole plate.According to dust from pole plate
The mode of disengaging is different, and electrostatic precipitator is divided into two kinds of forms of dry type and wet type.Dry electrostatic cleaner is with rapping or rotation
The mode of brush departs from dust, and wet cottrell is in the way of the moisture film that flows to depart from dust.
Wet cottrell makes dust collection in flue gas as a kind of terminal purifying equipment using the mode of electrion

Often good removal effect, can control its discharge from source, be widely used in electric power, iron and steel, chemical industry, weaving, cement, ceramics
And the waste gas pollution control and treatment of the industry such as glass, can effectively solve the problem that gypsum rain, blue smoke plumage or white cigarette problem, effect highly significant.
But traditional wet cottrell has a disadvantage that：1. traditional plate electrode, wire electrode, rod-shaped electrode
Corona insufficient strength is high, it is necessary to obtains high dust removing rate by improving voltage and prevents arc extinguishing from affecting；2. usual sour gas is in quilt
Trap after diluted acid is formed between pole plate and moisture film, diluted acid meeting etching apparatus affects service life；3. air-flow is interelectrode at each
Skewness, or even have at " dead angle ", reduce efficiency of seizing dust；4. traditional circular electric pole pipe is in distress accurately keeping concentric
Problem, makes electric field uneven, easily causes frequent electric spark, affects entirety to catch dirt effect；5. the nozzle of usual spraying layer simply sets
Put in electrostatic precipitation component upper end, the distribution of nozzle location is generally straightforward, easily produce spray dead angle.Additionally, nozzle shape
Into flushing moisture film cloth it is on dedusting pole surface and uneven, easily form trench current and speckle spot.Can send out after dirt accumulation
Raw electrode failure.Due to rinsing the uneven of moisture film, flue gas humidification spraying need to be set in dedusting component lower end, although compensate for water
The uneven problem of film, but easily form the phenomenon of corona blocking；And vaporific nozzle is capable of achieving more uniform flushing moisture film, but hold
Conductive droplet is easily formed, causes electric field short circuit.
Therefore, those skilled in the art need a kind of energy of offer badly and ensure that the uniformity of current, cathode line are put in pole pipe of gathering dust
Electric reliability, operation stability, and then improve the wet cottrell of efficiency of dust collection.
