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 treatment of the saturation wet flue gas of a large amount of droplets, the intractability with reality.In order to solve fine dust, particulate
Separated Deng the small miscellaneous dirt of particle diameter, part of generating units is processed 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 structure, reliable, energy consumption are low
And be used widely.Bundled tube dedusting demister is a kind of gas-liquid separator based on centrifugal force separate, using rotary pneumatic
The centrifugal action of stream, the drop that will be 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, big drop again by the liquid film capture of cyclone cylinder surface so that real
Now separated with gas phase and removed, with pressure drop it is small, except fog effect preferably, simple structure, transformation implement it is simple the advantages of, especially fit
For the waste gas demisting with solid or with salinity in acid mist after wet desulphurization.However, for such demister, void tower
Flow velocity separative efficiency influence of the velocity in pipes on demister in other words is notable, typically, within the specific limits, with velocity in pipes
Increase, the removal efficiency of demister is improved because air-flow makees rotational flow after through spiral-plate leaf gap, with
The increase of empty tower gas velocity, the tangential velocity of air-flow becomes big, and the centrifugal force suffered by the drop carried secretly in air-flow also can accordingly increase
Greatly, so as to be conducive to drop to get rid of the purpose that separation is reached to wall；At the same time, with the increase in pipe, the turbulence journey of air-flow
Degree increases, and drop reentrainment phenomenon is increasingly severe, and reentrainment is acted on mainly due to both sides：One is that drop is being touched
Atomization when hitting, two be high velocity air shearing force on the Free Surface of liquid film, when reentrainment amount exceed certain value after,
The separative efficiency of demister also declines therewith.
As can be seen here, there is contradiction in velocity in pipes and efficiency of dust collection, maintain efficiency of dust collection higher then to improve pipe
Interior flow velocity, and flow velocity is too high, and the ratio of reentrainment greatly improved, so as to cause the decline of efficiency of dust collection；On the other hand,
The load of boiler often fluctuates, and changes generally between 30~110%, so also just causes the change width of velocity in pipes
Degree is huge.In order to balance above-mentioned contradiction, prior art generally uses the processing method of compromise, namely with a specific load point
(such as 100% load or 70% load) is designed as design point, when actual motion load is higher than significantly the design point
When, it is low that reentrainment effectively causes removal efficiency, and when actual load is significantly less than the design point, centrifugal force is not enough and lead
Cause separating effect not high, the requirement of discharge index cannot be met when serious.

Also there have part of generating units to be above-mentioned to avoid the occurrence of, and optimal flow rate is taken with less load, such as by 80%
Velocity in pipes is 6m/s when load, and in this case when load rises to 100%, velocity in pipes is 7.5m/s, and demisting is removed
Dirt efficiency is higher, but reentrainment is also very serious, causes overall efficiency relatively low；When load is down to 60%, velocity in pipes is
4.5m/s, the centrifugal force that swirl vane is produced declines, the reduction of demisting efficiency of dust collection；In this case only near designed load point
Efficiency preferably, the reduction of dedusting demisting efficiency can be all caused after deviateing load because reentrainment or centrifugal force decline.

Pass through in unit, velocity in pipes is 6.0038m/s, and velocity in pipes is basically identical during 100% load, demisting efficiency of dust collection keeps
Stabilization；When load is further reduced to 60% or so, air quantity now is also reduced to 600000m3/ h, can now close
(100%-60%) × n=147 (147.2, be 147) individual open and close type component after rounding, such flue gas only from remaining 221 not
Pass through in the rotational flow dust-removing demisting unit of closing, velocity in pipes is 6.0054m/s, and velocity in pipes basic one during 100% load
Cause, demisting efficiency of dust collection keeps stabilization.So by the folding quantity reality of the regulation open and close type component under different loading condictions
The stabilization of existing velocity in pipes, so as to ensure the centrifugal force of swirl vane, reaches the effect that efficiency keeps stabilization.Certainly, it is above-mentioned to be
Optimal implementation, i.e. each rotational flow dust-removing demisting unit for being provided with open and close type component are individually controlled, and this just needs each
