Technical field
The present invention relates to a kind of high-effective dust-removing block preparation methods, belong to dedusting and environmental protection technical field.
Background technique
With regard to the complexity of China's air contaminant treatment and it is arduous for, China be badly in need of it is a kind of can be first under living environment
Efficiently remove the high-effective dust-removing technology of haze particle in atmosphere.
Room air particle removal technology it is most mature be using HEPA filter core, this is also most of air purifier producers
The technical solution of use, however HEPA pressure drop is very big, leads to that power-equipment high noise, energy consumption is high, while HEPA can not be cleaned, must
It must regularly replace, therefore the expense of HEPA causes the operating cost of indoor air cleaner high.This research team uses
The method that line hairbrush is turned round in filling inside to porous media duct is prepared for the gas particles cleaning module of low vapour lock
(ZL201210418554.4), however the module must reasonably select and tie up dust agent formula, and otherwise below for 2~3 microns
Grain removal effect is bad.The technical solution washed by spraying is also used for certain air cleaning units, but will lead to Interior Space by spraying
Gas excessively humidifies, and its particle removal effect is not high, simultaneously because spray water is often tap water, wherein water hardness is led
The salinity of cause increases the granule number of room air after so that droplet is volatilized instead.This research team also developed the electrostatic of half wet process
Dedusting (demisting) device (CN201510593461.9) is gathered dust agent by being partially submerged in subsurface plectane, positive negative electricity
Property be staggered, the subparticle of load charge is captured, the device can to subparticle realize efficiently removal,
And avoid the secondary escape of dust during common dry method electrostatic precipitation, however the equipment structure is complicated, difficulty of processing compared with
Greatly, and necessary height level places, and the electrical breakdown accident between different electrical liquid baths otherwise can occur.
In conclusion current China needs, a kind of vapour lock is small, flux is big, simple and flexible dust-extraction unit, this is for realizing
Air cleaning in living environment reduces haze particle and is of great significance to the harm of human body.
This research team it is creative will turn round line brush dedusting module and electrostatic precipitation principle is coupled, obtain have it is good
The dedusting module of dust collection capacity, and its pressure drop is lower, while can realize to the minuteness particle in air and efficiently capture and go
It removes.
Summary of the invention
It is an object of the invention to obtain to have low vapour lock, high-throughput high-effective dust-removing mould by a kind of simple method
Block.The modular structure is compact, production method is simple, is very suitable to be removed the subparticle in room air.
The purpose of the present invention is what is realized by the following technical solutions: this high-effective dust-removing module is by charged module and charged
Line brush dedusting module composition is turned round, it is first charged to the dust progress in air-flow using charged module in dust removal process, that is, make
The gas of dust-laden flows through the electric field for being mounted with the charged module of corona discharge electrode and dust collector pole, thus it is charged to the dust progress in air-flow,
Charged torsion line brush dedusting module is then caused air flow through, charged torsion line brush dedusting module is the gold with more than one airflow channel
Belong to module, airflow channel is parallel to each other, and channel is cylinder, is packed with inside airflow channel and turns round line brush, each airflow channel
The brush handle of interior torsion line brush is interconnected by conducting wire or guide rod, and load voltage, at the same the outer wall load of metal module with
Turn round the opposite voltage of line brush brush handle, turn round between line brush brush handle and the inner wall of metal module airflow channel by the bristle of torsion line brush every
It opens, due to turning round opposite charge between line brush brush handle and metal module airflow channel inner wall, by load positive electricity or negative in air-flow
The particle of electricity will be moved with the principle that there is a natural attraction between the sexes to the inner wall for turning round line brush brush handle or metal module airflow channel, is finally completed
Dedusting, meanwhile, it turns round the one layer of insulation of coating of line brush bristle surface and ties up dust agent, to be adhered fixed to dust particles, work as dedusting
When module adsorbs excessive dust, dust therein is washed off by the method for washing and module is made to realize regeneration.
This air dedusting purifier is further characterized in that: the corona pole tension of the charged module of this clarifier front end is -3
