Description
Technical field
The present invention relates to air-conditioning, particularly the ozone treatment of air-conditioning.
Background technology
Air-conditioning has become a part for people's life as the equipment of exchange heat, it greatly improves the comfortableness of people's life., along with human residential environment's deterioration, in order to improve air quality, air-conditioning has adopted the devices such as electronic dust catcher, anion, ozone generating-device and screen pack.Although ozone kill bacteria, ozone also has harm, and not a kind of directly pollutant of ozone, but oxygen and nitrogen oxide etc. issue in secondary pollution that third contact of a total solar or lunar eclipse chemical reaction forms or closed environment and assemble and pollute in effect of sunlight.In the impression of most people, ozone layer is to preserve our planet to exempt from the person who has rendered outstanding service of ultraviolet damage, is difficult to understand ozone and why pollutes the environment.Ozone is not directly discharged into the pollutant in atmosphere, but oxygen, nitrogen oxide (NOx) and VOC (VOCs) issue in effect of sunlight the secondary pollution that third contact of a total solar or lunar eclipse chemical reaction forms.As strong oxidizer, ozone almost can react with any biological tissue, and it is the main component of photochemical fog (the harmful mixing smog forming because of illumination reaction).Except above-mentioned method can produce ozone, the spark of emitting in motor rotation also can produce ozone.As Xerox in use, owing to adopting corona charging, can make oxygen molecule (O2) in surrounding air produce ionization, form atomic oxygen (O), atomic oxygen is combined with ambient oxygen molecule and is formed ozone (O3).Equally, the electrion of electronic dust catcher, also can produce ozone; The condition of ozone generating is high pressure and ultraviolet radiation, is required to be ion chamber high pressure is provided in employing electrostatic precipitation process, in the process of dedusting, can produce micro-ozone, and this is the inevitable problem of the whole world all employing electrostatic precipitations principle clearing machine.But these ozone, in airtight environment, As time goes on, and can be cumulative, can cause the harm to user.
The ozone exceeding standard is invisible killer, can cause the harm such as people's neurotoxic, dizziness headache, visual impairment and failure of memory.For example, in air, ozone concentration, in the time of 0.012ppm (1ppm be 1,000,000/) level, can cause skin urtication, eyes, nasal cavity, respiratory tract irriate, and PFT is influenced, occurs cough, breathes hard and the symptom such as pectoralgia.The monitored data demonstration of some urban health departments of the U.S., in air, level of ozone is brought up to 0.05ppm, and the number of seeking medical advice of being admitted to hospital on average rises 7%～10%.
At normal temperatures and pressures, ozone stable extreme difference, can be decomposed into oxygen at normal temperatures voluntarily; Its density is 1.5 times of oxygen.Ozone has strong impulse, and sucking excessively has certain harm to health.Content is the ozone below 1%, and in the air of normal temperature normality normal pressure, half life of decomposition is 16h left and right.Along with the rising of temperature, decomposition rate is accelerated, and when temperature exceedes 100 DEG C, decomposes very violently, while reaching 270 DEG C of high temperature, can be converted into immediately oxygen.The decomposition rate of ozone in water is than fast in air.In the aqueous solution that contains impurity, ozone is returned to rapidly the oxygen that forms it.While being 6.25 × 10-5mol/L (3mg/l) as Measuring Ozone Concentration in Water, its half-life is 5～30min, but decomposition rate is slower in pure water, if the half-life in distilled water or running water is approximately 20min (20 DEG C), but in redistilled water, after 85min, ozone decomposed only has 10%, if when water temperature approaches 0 DEG C, it is more stable that ozone can become.Ozone is very stable in ice, and its half-life is 2000.The half-life of ozone is only 30-60min in water, and relevant with temperature and humidity.
National Specification, in the air of residential area, ozone one hourly average maximum permissible concentration is 0.1mg/m
3.When the concentration in room is 0.1mg/m
3time, through converting, the ozone concentration in room is just in time 100/470=0.21ppm.
Concrete ozone ppm is converted into mg/m3 and is calculated as follows:
A(mg/m3)＝M*E(ppm)/22.4
Note: A is concentration (mg/m3), and E is ppm number, and M is relative molecular weight
For example, ozone molecule amount is 48
1PPM＝1mg/m3*22.4÷48＝0.47mg/m3
Find through research, in airtight environment, the ozone concentration that IFD module (electrostatic precipitation module) discharged at 4.5 hours exceedes 0.13PPM, and namely ozone concentration has approached 0.1mg/m3 (0.1mg/m3 converts into PPM, is 0.21ppm); In airtight environment, IFD module is moved 8 hours continuously, and ozone exceedes 0.356PPM, and (0.1mg/m3 converts into PPM, for 0.21ppm), namely ozone concentration has exceeded 0.1mg/m3, is greater than the 0.1mg/m3 of national regulation, undesirable.
This is mainly current electrostatic dust collection equipment, if it is better to remove PM2.5 effect, inevitable voltage is more than 6000V; If more than voltage 6000V, in airtight environment, long-time ozone must exceed standard.
Electrostatic dedusting technology utilizes anode discharge to make in air the particulate pollutant lotus that becomes positively charged, and uses Coulomb force effect that charged particle pollutant is adsorbed on dust collect plant and is purified air.And adopt this kind of technology to have no idea to eliminate the bacterium on particulate pollutant, and can produce ozone in use positive corona process.Because the half-life of ozone is longer, in air, can reach 16 hours, if assembled for a long time, will inevitably bring impact to health.
Current prior art, in the time using IFD module, adopts and reduces operating voltage and occur to reduce ozone to reduce electric-field intensity, or built-in ozone adsorbent equipment solves the harm of ozone generating on this type of air purifier.Method that can this solution, has brought the reduction of removing the effect of PM2.5.
Ozone also has no small benefit to the mankind.As ozone blast pipe hung over to 1.7 meters of height above, discharge ozone 20--30 minute, can effectively remove the peculiar smell of indoor flue dust or ornament materials, depositing dust sterilizing, increase oxygen content in air, fresh air, allow you enjoy at home after rain pure and fresh air as forest (can be used for family, office, meeting room, public place of entertainment smoke abatement, dedusting, sterilize, de-taste).
In addition, because ozone is the extremely strong unstable gas of a kind of oxidisability, the molecular weight of ozone and concentration are subject to the impact of many factors, and wherein cavity temperature is one of epochmaking factor; The ozone half that decays in 1 minute at 30 degree left and right Shi Hui.In the time of 40～50 DEG C, decay reaches 80%, and exceeding 60 DEG C of ozone can decompose at once.
Ozone easily decomposes, and under labile state, the half-life of ozone is 22～25 minutes, and the fading rate of hour is 61%, and in 1% ozone water solution, the half-life is about 16 minutes, and temperature is higher, and humidity is larger, and the half-life is shorter.
