Description

A kind of ultraviolet light circuit for being applied to air purifier

Technical field

The utility model is related to the fields such as purification of air, is a kind of ultraviolet light for being applied to air purifier specifically Circuit.

Background technology

Haze, as the term suggests it is mist and haze.But the difference of mist and haze is very big.Dust, sulfuric acid, nitric acid in air etc. What the aerosol systems of grain thing composition caused dysopia is haze.Haze is exactly gray haze (mist and clouds in the twilight).

The aerosol systems that mist is made up of the small water droplet or ice crystal that are suspended in a large number in surface air.Come across more Autumn and winter season, is the product of condensation vapor (or sublimating) in ground layer air.The presence of mist can reduce air transparency, enable Degree of opinion deteriorates, if the horizontal visibility of object is reduced within 1000 meters, will just be suspended in the steam in surface air The weather phenomenon for condensing (or sublimating) thing is referred to as mist (Fog).

The particles such as dust, sulfuric acid, nitric acid, the organic hydrocarbon compounds in haze (m á i), also referred to as gray haze (smog) air also can Make air muddy.The horizontal visibility of object is referred to as into mist or mist (Mist) in this phenomenon of 1000～ten thousand metres.Shape Atmospheric humidity should be that (in the presence of a large amount of nuclei of condensation, relative humidity not necessarily reaches 100% may for saturation during mist formation There is saturation).The light and wavelength relationship scattered due to the mist that aqueous water or ice crystal are constituted is little, thus mist seems to be creamy white Or Bluish white and grey.

Haze weather is a kind of atmosphere pollution state, haze be in air various suspended particulate substance content overproofs it is general Statement, especially PM2.5 (particulate matter of the equivalent aerodynamic diameter less than or equal to 2.5 microns) is considered as to cause haze sky " arch-criminal " of gas.With the deterioration of air quality, increasing occurs in thick weather phenomenon, and harm increases.Chinese many areas are cloudy Haze weather phenomenon is incorporated to mist together as diastrous weather early-warning and predicting.It is referred to as " haze weather ".

Haze is molecular by grains such as the dust in air, sulfuric acid, nitric acid, organic hydrocarbon compounds.It can also make air Muddiness, the visual field obscures and causes visibility deterioration, if horizontal visibility is less than ten thousand metres, this non-aqueous thing is constituted The obstruction to vision that causes of aerosol systems be referred to as haze (Haze) or gray haze (Dust-haze), Hong Kong Observatory claims mist and clouds in the twilight (Haze)。

Haze mainly by sulfur dioxide, nitrogen oxides and pellet this three constitute, they are combined with fog Together, sky moment is allowed to become cloudy gloomy.The english abbreviation of particulate matter is PM, and Beijing monitoring is fine particle (PM2.5), Namely equivalent aerodynamic diameter is less than or equal to 2.5 microns of contaminant particle.This particle is both in itself a kind of pollution Thing, is again the carrier of the noxious materials such as heavy metal, polycyclic aromatic hydrocarbon.

The distribution of haze particle is than more uniform, and the yardstick of gray haze particle is smaller, from 0.001 micron to 10 microns, puts down About in 1～2 microns, be invisible to the naked eye diameter aerial showy particulate matter.Due to particles such as dust, sulfuric acid, nitric acid The haze of composition, the longer light of its dispersion wavelength is relatively more, thus haze seems in yellow or orange grey.

Mist and haze something in common are all obstruction to vision things.But mist has very big difference with the Crack cause and condition of haze. Mist is swim skyborne a large amount of small water droplets or ice crystal, and formation condition will possess higher water-vapo(u)r saturation factor.

General relative humidity is less than air muddiness when 80%, and visibility deterioration is that haze is caused caused by the visual field is fuzzy, Air when relative humidity is more than 90% is muddy, and visibility deterioration is that mist is caused caused by the visual field is fuzzy, relative humidity between Air when between 80～90% is muddy, and visibility deterioration is that the mixture of mist and haze is caused jointly caused by the visual field is fuzzy, But its main component is haze.The thickness of haze is than larger, reachable 1～3 km.

Relative air humidity is often up to 100% or close 100% during appearance mist.Mist has to go out with the diurnal variation of air humidity Sooner or later more typically or enriching now, relative the phenomenon for even disappearing is mitigated daytime.There is level of significance visibility during mist and be less than 1KM. It is referred to as mist as level of significance 1～10KM of visibility.Mist refers to that because of the condensation vapor for suspending in air low visibility is public in 1 In when weather phenomenon.

Haze when occurring relative humidity less, and the relative humidity in mist be saturation (in the presence of if any a large amount of nuclei of condensation, Relative humidity not necessarily reaches 100% may there is saturation).Haze is caused by pollutants such as vehicle exhausts.Relative humidity Visibility deterioration is that the mixture of haze and mist is caused jointly caused by air muddiness visual field when between 80～90% is fuzzy 's.

When condensation vapor aggravation, air humidity increase, haze will be converted into mist.When haze is that haze occurs with the difference of mist Relative humidity is little, and the relative humidity in mist is that (in the presence of a large amount of nuclei of condensation, relative humidity not necessarily reaches saturation 100% may there is saturation).

In fact mist has very big difference with haze from for certain angle.Such as：There was dampness in the air during appearance mist；When there is haze Air then relatively dry, relative air humidity is generally below 60%.Its Crack cause is due to a large amount of imperceptible grit, cigarettes Grain, salt grain etc. are equably swum in the air, make air of the level of significance visibility less than 10KM mix the phenomenon of erosion.The diurnal variation of haze It is general unobvious.When air mass does not have big change, and air bolus are relatively stablized, lasting time of occurrence is longer, sustainable 10 days sometimes More than.All it is because of a large amount of atomic thin dirt in the air that swim due to weather phenomena such as haze, mist, sandstorm, sand, floating dust Grain or soot etc. affect to cause level of significance visibility to be less than 10KM.Sometimes meteorological professional is made all to be difficult to distinguish.Must tie Close the factors such as weather background, state of the sky, air humidity, color smell and satellite monitoring and carry out comprehensive analysis and judgement, just can draw What correctly conclusion, and the weather phenomenon of mist and haze can be changed mutually sometimes.Haze has after the respiratory tract of suction people to human body Evil, such as long-term suction, severe patient can cause death.

The source of haze is varied, such as vehicle exhaust, industrial discharge, building airborne dust, waste incineration, or even volcano spray Send out etc., haze weather is typically what various pollution sources immixtures were formed.But in the haze weather of each department, different pollution sources Effect degree it is each variant.

Haze weather has it from ancient times, and the mankind's activity such as slash-and-burn cultivation and volcanic eruption or natural phenomena may all cause haze Weather.But after the mankind enter the fossil fuel epoch, haze weather just really threatens the living environment and body of the mankind and is good for Health.Industrialization and urbanization drastically causes the energy rapidly to consume, population high aggregation, environmental destruction, is all haze sky The formation of gas hides the foreshadowing.

The formation existing " source " of haze, also there is " accomplice ", here it is it is unfavorable for the meteorological condition that pollutant spreads, once Pollutant is gathered in the case where the meteorological condition of static state is chronically at, and is easy for forming haze weather.Haze is formed with three key elements：

One is the physical base source for generating graininess airborne dust.There are Loess Plateau maximum in the world, its soil matter in China Ground most easily generates graininess airborne dust particulate.

Two is that differences in motion causes airborne dust.For example, in the middle of road the soil of flower nursery and street serratd edge rain or water-sprinkling after If having mud stream to road, after one hour dry, a large amount of airborne dusts will result in by the rotation of wheel one, even if these particulate matters fall Ground is gone back to, also can constantly be crossed because of automobile, city overhead is thrown to again.

Three is that airborne dust Ji Yuan and differences in motion process are collected in the range of certain space, and particle finally gathers with hydrone tuberculosis Into haze.At present, in the city of the flat highlands of China's loess more than 350, haze construction three elements storage is quite in plenty.

Purification of air refers to that providing sterilizing, depositing dust for indoor various environmental problems removes haze, dispels harmful finishing The total solution such as residual and peculiar smell, raising is made the life better, office conditions, promotes physically and mentally healthy.Indoor environmental pollution thing Mainly include radgas, mould, particulate matter, finishing residual, second-hand-cigarette etc. with pollution source.
