Description
Technical field
The utility model belongs to technical field of air purification, more particularly to a kind of to determine powered granular absorption efficiency
Device.
Background technology
Haze is the complicated aerosol systems collectively constituted by droplet and haze grain, and when haze weather occurs, visibility is drastically
Decline, influence flight landing, cause congestion in road or even occur traffic accident.The aggravation of atmosphere pollution simultaneously, is not only exhaled people
Desorption system, immune system, cardio-cerebrovascular etc. are caused to have a strong impact on, and industry, agricultural, aquaculture, tourist industry etc. are made
Into having a strong impact on, or even the influence national economic development, destruction ecosystem balance.Especially haze weather when air in gas it is molten
Glue makes stuffy, and many harmful substances can enter human body with the breathing of people, and enters discharge is difficult after human body, can rest on
Alveolar causes harm, and long-term suction easily causes the disease such as cough, uncomfortable in chest, runny nose, pharyngitis, rhinitis, bronchitis even to trigger various cancers
Disease.From evil it is big this, the deep, danger of the influence of haze.We must further investigate to this, in the hope of early settlement this
Problem.
For this problem of haze, many scholars propose different control measures, such as some scholar's research find mist
Formation and development of the various microbial activities to haze all has an impact during haze, and they think should be with atmospheric environment and bioscience
Concerted effort is studied and preventing and treating haze；Some scholars then think that the clean energy resource generation such as biomass energy, solar energy can be greatly developed
For fossil energy；Someone's research is found in haze containing plurality of heavy metal ion, and serious threat is caused to health, therefore should
It is a large amount of to build urban green belts, play the effect of plant absorption heavy metal；It is believed that bad border popular science knowledge should be strengthened, energetically
Develop public transport instrument, strengthen physical training, improve autoimmunity etc.；It is believed that vehicular emission mark should be set
Standard, motor vehicle installs exhaust gas cleaner Hou Zaishang roads additional；Somebody thinks that fire coal should be reused after desulphurization and denitration, Industry Waste
Gas is answered and discharged again after desulphurization and denitration.But these measures are cured the symptoms, not the disease, and are made a thorough investigation, haze still will set about from source, accelerate
Promoting Industrial structure and layout are adjusted, propulsion energy-saving emission reduction.
The purification style of current air purification field mainly have filtration method, absorption method, anion method, low-temperature plasma method,
Fresh air method etc..Wherein filtration method and absorption method are the traditional purification methods of comparison.Its advantage is simple structure, facilitates easy-to-use；Its
Have the disadvantage can not long-time continuous purification air, using after a period of time must to filter screen clear up or change adsorbent, no matter
It is not preferable selection from convenient or economic angle.The principle of anion method is that the gas molecule in air is worked as by energy
When exciting, its outer-shell electron can jump out track formation cation.The free electron jumped out is attached on another gas molecule, with regard to shape
Into anion.The method of artificially generated anion has ultraviolet irradiation, thermionic emission, radioactive substance radiation, electric charge point
Six kinds from, high-pressure water jet and corona discharge etc..Its advantage is to remove dust, pollen, bacterium, smog, the peculiar smell in air
Deng pollutant, it has the disadvantage easily to make dust absorption on the surface such as wallpaper and glass, it is impossible to clear out of interior.Simultaneously as generally
The ion generator used can be produced with ozone, negative ion concentration it is too high it is too low can all lose natural equilibrium, this situation is held
It is continuous to influence health too long.The advantage of low-temperature plasma method is can to handle the volatile organic matter of low concentration in air
And microorganism.It has the disadvantage can not thoroughly degradation of contaminant, and often with the generation of other accessory substances and ozone, so as to draw
Play secondary pollution.The advantage of fresh air method be can effectively drive away pernicious gas and it is mould proof eliminate the unusual smell, have the disadvantage to need periodic replacement
Screen pack, if irregularly changing screen pack, it is likely that as indoor pollution sources.
In recent years, it has been found that haze can have an impact to transmission line of electricity and impulsive discharge path, then some scholar's research
It was found that haze is powered.ErkkiLamminenet al. (2011) research points out that original particle is in atmosphere approximately in electricity
Neutrality, and newly discharge or react generation particle can because particle size, material and generation method difference and with different electricity,
Especially high temperature and collision can sharply increase the carried charge of particle.Accordingly, it is considered to which electrostatic removes haze mode, Dutch art man reaches
En Luosaijiade proposes a method that haze is administered using electrostatic absorption principle.However, nowadays the electrostatic of in the market is removed
Haze device and electrostatic precipitator are all that air ionization is produced into powered using high voltage power supply using anion method in pole plate side
Grain, thus substantially or anion method.
