Description
Technical field
This utility model relates to a kind of electrostatic precipitation module, espespecially a kind of by corona charging unit
With the electrostatic precipitation module that collecting unit of dust is combined into a module.
Background technology
China Meteorological Administration has revised haze Alert Standard January 28, by PM2.5 index
(< 2.5um/m3) as one of important indicator issuing early warning, New England Journal of Medicine refers to
Go out PM2.5 (< 2.5um) and often increase by 10 micrograms, the lung cancer incidence of 10% will be improved,
All kinds of cancers also can improve 5%.World Health Organization (WHO) is also mentioned: often increase by 10 μ g/m3's
PM10 will improve the mortality rate of 0.2-0.6%, and the PM2.5 often increasing by 10 μ g/m3 will improve
The heart and lung diseases fatality rate of 6-13%.Owing to the dust particle in environmental gas has pole to human body
Big harm, therefore the structure of gas cleaner also continuously improves.
Although gas cleaner kind on the market is a lot, but for can really remove PM2.5
(comprising the fine particles such as nm dust virus, antibacterial, mycotic spore and dust mite Excreta) clear
Clean machine is the most few, and electrostatic dust arrester is owing to possessing high fine particles removal efficiency, power saving, low
Crushing and the characteristic without filter material, it is contemplated that the main flow of gas cleaner will be become in the future.But also because of
Need the time of bigger dust and electrode contact, therefore to reach portable design the most difficult.
Existing electrostatic dust arrester mainly includes region of discharge and the accumulation area being provided separately, its
Middle region of discharge comprises corona and reference electrode, in order to produce corona discharge；Accumulation area is then by just
Pole forms with negative plate, in order to produce an electric field, to collect soil.As it was previously stated, by
Two regions being provided separately in corona zone and collecting region, therefore can increase distribution complexity,
Structure complexity and overall volume, make cost high simultaneously and maintenance be difficult to.
Additionally, the most industrial or general commercially available electrostatic dust arrester, mostly pass through multiple-piece
Or honeycomb structure reaches to increase the purpose of the time of dust and electrode contact, but, either
Multiple-piece or honeycomb structure, all can be more difficult in follow-up maintenance with cleaning.
Therefore, how to provide a kind of and corona charging unit be combined as a whole with collecting unit of dust,
Structure can be simplified, reduce volume, reduction cost and " the electrostatic precipitation mould for ease of maintenaince maintained
Block ", it is particularly suited for commercialization and household application market, is a current important topic.
