Purification system.
Background technique
In recent years, every autumn and winter was especially after the winter, and domestic Middle Eastern can meet with haze frequently, and have
The trend of haze normalization.There is environment specialist's analysis, haze is likely to replace smoking No.1 pathogenic " killer " as lung cancer.Wherein
With Jing-jin-ji region, the Yangtze River Delta, Chengdu-Chongqing, central plain area etc. for global pollution most, the average annual concentration of PM2.5 is more than 70 μ g/m3, it is more than
The 2 times or more of national standard, higher than 7 times or more of WHO standard.
And the haze dust in air, in addition the phenomenon that environmental pollution caused by interior decoration causes people sick, residual, dead is
Become social concern, these polluted gas through science confirm it is very big to body effect, be easy to cause respiratory disease, cancer,
Leukaemia, neurological disease especially endanger pregnant woman, children, old man serious.Therefore, particularly significant for indoor purification.Normally
Under environment, human body sucks about 500,000 particles of lung every time, and when air is contaminated, the particle of human body sucking is more than this
100 times.Haze weather easily recurs asthma, including bronchial asthma, bronchitis, allergic rhinitis and variability cough
Deng.
Haze weather is also " Health Killer " of cardiovascular patient, serious gray haze may make to have respiratory disease and
Old man's state of an illness of cardiovascular disease induces, or even heart attack, causes life danger.Haze day is to human body cardiovascular and cerebrovascular disease
Influence is also very serious, can hinder normal blood circulation, leads to cardiovascular disease, hypertension, coronary heart disease or cerebral hemorrhage disease hair, or can
Angina pectoris, myocardial infarction, heart failure etc. can be induced, chronic bronchitis is made cor pulmonale etc. occur.Expert points out, holds
Continuing the big greasy weather can also have an impact to the psychology of people, and since greasy weather light is weaker, air pressure is lower, some people can generate spirit in the greasy weather
Slack, depressed phenomenon, or even can stimulate or aggravate the state of people's mental depression.
For the haze and normalization trend got worse, the use of air cleaning system seems particularly necessary, now city

It enters in electrostatic precipitator, indoor top space is entered by air inlet 800 after treatment, to the fresh sky of indoor injection
Gas.It is additionally provided with heating and dehumidification device 740 on the arrival end of the electrostatic precipitator, is removed for carrying out heating to mixing air
It is wet, it avoids since steam is excessively high and influence the normal operation of electrostatic precipitator in air.Interval in the electrostatic precipitator
Several dust collecting electrodes 720 are provided with, corona discharge electrode 730 are provided between dust collecting electrode 720 described in every two, the dust in air is by electricity
Dizzy pole 730 induces negative electrical charge, and is adsorbed by positively charged dust collecting electrode 720, thus realize dedusting, dust collecting electrode 720 and corona discharge electrode
730 are alternately arranged, and increase the contact surface of air Yu dust collecting electrode 720 and corona discharge electrode 730, to improve the absorption of electrostatic precipitator
Dust removing effects and processing flow, the dust collecting electrode lower end is provided with ash bucket 710, for collecting the dust in dust collecting electrode, it is described into
Third filter 810 is provided in air port, the third filter is high efficiency particulate air filter, is carried out most to the air after electrostatic precipitation
Filtering afterwards, filters out fine dusts, to improve Cleanliness grade.
In a kind of embodiment, the flow area of the return air channel is greater than the flow area of the top passageway, with for time
Wind provides enough cushion spaces, avoids causing no enough return air to pass through the electric induction since return air amount moment is insufficient
Device, return air slow transit through the return air channel of bigger sectional area, then accelerate into the top passageway of small cross sections product, with
Realize that return air collides coalescences, the electrical induction device and charged dust from two spray equipment outlet end outputs with certain speed
It is provided with insulating layer in the indoor ceiling 11 of device lower end, to reinforce avoiding causing to endanger to interior to indoor insulation protection
Danger.
In a kind of embodiment, interior is provided with several pm2.5 detectors, can be arranged on interior side wall and described time
Air port, the terminal of each pm2.5 detector are connected with controller, the controller respectively with the Electric air valve and described
Filter bank connection is entered the wind, the indoor dustiness that controller is arrived according to pm2.5 detector test carrys out electronic wind described in linkage control
The air output of valve and the air inlet filter bank then increases the exhaust air rate of Electric air valve when indoor dustiness is higher, adds simultaneously
The big air inlet filter bank fresh air conveying capacity, accelerates the replacement of room air；It, then can be appropriate when indoor dustiness is lower
Reduce the exhaust air rate of Electric air valve, to increase the regeneration amount of return air, while reducing the air inlet filter bank fresh air conveying
Amount can effectively reduce entire air cleaning system and air handling system on the basis of guaranteeing Cleanliness grade
Energy consumption.
From the above mentioned, in the present invention, after the fine dusts in return air are handled by two electrical induction devices, spray equipment,
Preliminary coalescence improves the adsorption effect of electrostatic precipitator at the dust of larger particles, meanwhile, fine dusts by after charged,
Coalescence is more easily captured by the dry fog of spray equipment；Meanwhile the dust after preliminary coalescence passes through the absorption of charged dust collect plant, has
Effect has filtered out most dust, and further, the dust being not filtered out exports head-on collision from two charged dust collect plants, into
One step coalescence is conducive to electrostatic precipitator and adsorbs dedusting, improve indoor cleaniliness classs at the dust of larger particles；Into one
Step, the fine dusts head-on collision of return air and fresh air enters in electrostatic precipitator after being mixed into the dust of larger particle, tiny
Dust passes through multiple mixing coalescence, after being adsorbed substantially by electrostatic precipitator, enters interior, further improves indoor clean
Cleanliness grade.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and legend shown and described herein.
