Description
Technical field
The high-efficiency swirl-type dedusting demister of a kind of fairing and application fairing is the utility model is related to, is belonged to
Exhaust-gas treatment field, it is mainly used in dust and droplet in the laggard one-step removal flue gas of wet desulphurization.
Background technology
At present, the existing coal unit in China generally uses lime stone --- gypsum wet flue gas desulfurizing technique, from absorption
In the wet flue gas of tower discharge in addition to the dust not eliminated containing part front end deduster, it is in fine mist shape also to contain substantial amounts of
State lime stone, gypsum slurries etc., with the raising increasingly of state environmental emissioning standard, depth need to be carried out to the neat stress after desulfurization
Dedusting, and reduce droplet discharge capacity.According to newest promulgation《Fossil-fuel power plant atmospheric pollutant emission standard》, to the powder of smoke stack emission
Dust concentration proposes 5mg/m3 requirement.
The dedusting demisting of flue gas is technique most commonly seen in fume purifying processes, and type is varied, but for containing
For the processing of the saturation wet flue gas of a large amount of droplets, there is the intractability of reality.In order to solve fine dust, particulate
Deng the small miscellaneous dirt separation of particle diameter, part of generating units uses deflection plate demister+WESP（Wet type electrostatic precipitator）Handled, but for
Retrofit work amount is huge for built desulfurization unit, generally existing absorption tower body need to be increased, strengthening of foundation, transforms the cycle
It is long, and it contains substantial amounts of high voltage electric equipment, operation and operation difficulty are larger.
A kind of substitute technology of the high-efficiency swirl-type dedusting demister as WESP, because of its simple in construction, reliable, energy
Consume low and be used widely.High-efficiency swirl-type dedusting demister is a kind of gas-liquid separator based on centrifugal force separate, profit
With the centrifugal action of swirling eddy, the drop carried secretly in air-flow is got rid of to wall peripheral, fine drop, fine solid particle in flue gas
The reunion that collides with each other of the finely ground particles such as particle, aerosol is condensed into big drop, and big drop is captured by cyclone cylinder surface liquid film again,
Separate and remove with gas phase so as to realize, have that pressure drop is small, defogging effect is preferable, simple in construction, the advantages that simple, is implemented in transformation,
The waste gas demisting being particularly suitable for use in after wet desulphurization in acid mist with solid or with salinity.
Due to the dust content in flue gas higher (being usually 20 ~ 50mg/ m3) and all it is the less particle of particle diameter, it is desirable to
The concentration of discharge is again relatively low (being usually 3 ~ 10mg/ m3), the multigroup eddy flow component of high-efficiency swirl-type dedusting demister generally use
The form of arranged in series in a cylinder, figure three give the schematic diagram of prior art high-efficiency swirl-type dedusting demisting unit,
Each dedusting demisting unit includes some grades of eddy flow components, and each eddy flow component includes several swirl vanes and a center
Cylinder, swirl vane are evenly distributed on the annular section between center drum outer wall and demisting unit cylinder inboard wall at an oblique angle
It is interior.When flue gas passes through dedusting demisting unit from bottom to top, in the presence of the swirl vane on eddy flow component, rotary motion, cigarette
Solid particle and partial drop in gas are thrown toward wall because the centrifugal force being subject to is larger, and it is past dirty then to form liquid film
It is dynamic, so as to realize the separation of dust in flue gas.This design form is less problematic in only one-level eddy flow component, and works as series
During more than two-stage, air-flow destroys being uniformly distributed for air-flow after Multi-stage spiral, and the air-flow with eddy flow revolves into next stage
Collision, eddy flow effect can weaken caused by stream component, influence treatment effect, and the effect needs that reach equal in other words are more
Processing series, the requirement of discharge index can not be met when serious.
