Description
Technical field
The invention belongs to dust removal and filtration technical field, specifically, it is related to a kind of minimum discharge dust arrester and ash disposal side
Method.
Background technology
At present, reduce smoke dust discharge concentration, the mainstream technology improving dust pelletizing system efficiency has wet static dedusting technology, low
The technology such as warm electrostatic precipitation technology, bag type dust removing technology.
After wet cottrell is usually placed in desulfuration absorbing tower, can effectively remove the smokeshade in flue gas
PM2.5、SO3The pollutant such as the desulfurated plaster droplet carrying in flue gas after microlayer model, hydrargyrum and demister, are a kind of efficient electrostatic
Cleaner unit.Ash on pole plate being shaken by rapping from dry electric precipitation device drops down onto unlike ash bucket, wet electrical dust precipitator be by
Water is sprayed onto in dust collecting electrode and forms continuous moisture film, and circulating water the flue dust of capture is washed in ash bucket and discharges with water.Due to not having
After rapping apparatus, will not produce reentrainment of dust in wet cottrell dust removal process, and discharge electrode is flooded profit so that electricity
There are a large amount of Charged Droplets in, greatly increase the submicron particle powered probability of collision, can under higher flue gas flow rate,
Capture more microgranules.Wet cottrell can significantly improve dedusting and remove SO3Effect.
Low temperature electrostatic precipitation technology passes through to reduce electric cleaner entrance flue gas temperature, typically drops to below acid dew-point temperature, from
And reduce the ratio resistance of flue dust, so that performance of precipitator is improved, reach raising efficiency of dust collection effect.Low temperature dedusting technology can have
Effect prevents electric cleaner from corona occurring, and after flue-gas temperature reduces simultaneously, exhaust gas volumn reduces, and flue gas flow rate also accordingly reduces, and removes in electricity
The time of staying in dirt device increased, and electric dust collector can more effectively capture to flue dust, thus reaching preferably
Dust removing effects.In addition, temperature is reduced to below acid dew point, the SO in flue gas3With H2SO4Microlayer model form exist, can adsorb
Collect to collecting plate, thus removing most SO in flue dust and together with flue dust3, simultaneously the alkaline matter in flue dust can in
And sulfuric acid droplets.
Bag type dust removing technology is come pollutant such as the dust in separation gas by filtering material, and dust passes through filtering material
When the filtration of filter screen that formed due to filtering material and be sized, adhere to, caught by filter screen by the effect such as inertia and electrostatic
Obtain.Continuing on with sack cleaner, the dust of screen surface accumulation thickens and leads to its hole less and less, such that it is able to
Capture trickleer dust so that cleaner unit has more preferably dust removing effects.When the dust on filter screen is too thick, its dedusting resistance
Greatly enhance, now then need to carry out ash disposal to filter screen, thus keeping the long-term efficient stable of cleaner unit to work.
The classification of cleaner unit is mainly according to its construction features, such as filter bag shape, filtering direction, air inlet position and remove
Grey mode is classified.
Wherein, the ash disposal mode of cleaner unit mainly has following three kinds：
(1) mechanical vibration mode.Hit filter bag by vibrating using machinery, so that being accumulated in the powder on filter bag surface
Dirt drops, can be so that using in the way of artificial or mechanical, this ash disposal mode is simple to operate, but effect deviation, and if shake
Dynamic excessive it is easily damaged filter bag, therefore using not extensive.
(2) inverse streamer mode.Inverse streamer mode refers to make filter bag deform using the air-flow in opposite direction with filtered airflow
Thus allowing dust to drop, can by blowing afloat, air-breathing or pressure-vaccum revolution by way of reach dedusting effect.
(3) pulse mode.Pulse ash disposal mainly uses pulse valve and compressed gas high speed is sprayed into filter bag, in compressed gas
While spraying into, because viscous effect also can bring the air being several times as much as spraying tolerance into, so that filter bag produces drastically swollen
Swollen and vibration, and then leads to dust to drop.By numerical simulation being carried out to cleaner unit interior flow field it can clearly be seen that pulse
For the dust removing effects of system, thus by the intensity and the frequency that adjust pulse, therefore this dedusting method has and preferably removes
Dirt effect, is able to extensive utilization.
And its air inlet mode mainly has two kinds, a kind of be filter bag inside air intake, outside air-out (inward flow filtration-type)；Another
It is the outside air intake of filter bag, internal air-out (outside filtering type).Due to the bag-type dusting fairly simple, therefore general using outside air intake
Device all employs outer filter technology.
The electric precipitations such as new wet static dedusting technology, low temperature electrostatic precipitation technology, rotating electrode type electrostatic precipitation technology
Although technology can reach relatively low concentration of emission, due to needing to use high voltage power supply, dedusting energy consumption is larger, equipment simultaneously
Maintenance cost is higher.
The operation energy consumption of bag-type dusting is relatively low, but the concentration of emission of the dust of the flue gas after this technical finesse typically exists
30mg/m3Below it is more difficult to reach 15mg/m3Below.In addition, the pulse ash cleaning technology used by existing bag-type dusting needs in a large number
Compressed air, ash disposal energy consumption is higher.Meanwhile, existing bag-type dusting running resistance is larger, and therefore operation energy consumption is also low.
Although new electrostatic precipitation technology can reach relatively low concentration of emission, its dust removal mechanism is by high voltage power supply
Produce highfield it is therefore desirable to larger energy consumption, in addition its relevant device is more, and the maintenance cost of equipment is higher.Additionally, adopting
Wet type or ultralow temperature dedusting, the humidity in flue gas greatly improves, and the H2SO4 of production easily produces corrosion to electrode, further
The maintenance cost of increase equipment.
And bag type dust removing technology conventional at present employs the pulse ash disposal dedusting technology of outside filtering type mostly, the removing of outside filtering type
Dirt device needs cage to support filter bag, easily produces the mutual abrasion between filter bag and cage during ash disposal.For manufacture and peace
Dress technical difficulty, with and cage deformation etc. factor, the length of filter bag and cage can not be long, is typically less than 10m.Such one
Come under the situation of equal floor space, the effective filtration area of cleaner unit is low, filtration velocity higher so that the mistake of filter
Filter efficiency is low, and dust emission concentration is higher, and equipment running resistance is higher.
Further, since the compressed air of outside that the source of the gas of existing pulse ash disposal adopts, therefore its ash disposal energy consumption is higher.
