Description
Technical field
The utility model belongs to exhaust-gas treatment field, and in particular to one kind is used in the laggard one-step removal flue gas of wet desulphurization
The bundled tube dedusting demister collected with liquid of dust.
Background technology
At present, the existing coal unit of 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, also containing substantial amounts of in fine mist shape
State lime stone, gypsum slurries etc., with the raising increasingly of state environmental emissioning standard, need to carry out depth to the neat stress after desulfurization
Dedusting.According to newest promulgation《Fossil-fuel power plant atmospheric pollutant emission standard》, the dust concentration to smoke stack emission proposes 5mg/
m3Requirement.
The dedusting demisting of flue gas is most commonly seen technique 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, the intractability with reality.In order to solve fine dust, particulate
Deng the small miscellaneous dirt separation of particle diameter, part of generating units is handled using deflection plate demister+WESP (wet type electrostatic precipitator), 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.
Bundled tube dedusting demister as WESP a kind of substitute technology, because its simple in construction, reliable, energy consumption is low
And be used widely.Bundled tube dedusting demister is a kind of gas-liquid separator based on centrifugal force separate, utilizes rotary pneumatic
The centrifugal action of stream, the drop carried secretly in air-flow is got rid of to wall peripheral, fine drop, fine solid particle particle in flue gas, gas
The reunion that collides with each other of the finely ground particles such as colloidal sol is condensed into big drop, and big drop is captured by cyclone cylinder surface liquid film again, so that real
Now separate and remove with gas phase, with pressure drop it is small, except fog effect preferably, it is simple in construction, transformation implement it is simple the advantages of, especially fit
For the waste gas demisting in acid mist after wet desulphurization with solid or with salinity.
(it is usually 20~50mg/m because the dust content in flue gas is higher3) and be all the less particle of particle diameter, it is desirable to
The again relatively low concentration of discharge (is usually 3~10mg/m3), bundled tube dedusting demister is generally using multigroup eddy flow component one
The form of individual " tube bank " interior arranged in series, prior art dedusting demisting unit includes some grades of eddy flow components, each eddy flow component
Include several swirl vanes and a central tube, swirl vane is evenly distributed on center drum outer wall and removed at an oblique angle
In annular section between mist unit cylinder inboard wall.When flue gas passes through dedusting demisting unit from bottom to top, on eddy flow component
In the presence of swirl vane, rotary motion, solid particle and partial drop in flue gas due to the centrifugal force being subject to it is larger and by
Get rid of to wall, liquid film flow down is then formed, so as to realize the separation of dust in flue gas.This design form is in only one-level
It is less problematic during eddy flow component, and when series exceedes two-stage, have a considerable amount of drops collected by wall secondary
Disperse and be entrained in air-flow, influence treatment effect, to reach that equal effect needs more processing series in other words, seriously
Shi Wufa meets the requirement of discharge index.
Utility model content
The defect that the utility model exists for existing above-mentioned technology provides a kind of bundled tube collected with liquid and removed
Dirt demisting unit and device.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of bundled tube dedusting demister collected with liquid, the device includes n bundled tube dedusting demisting unit,
