Description
Technical field
The utility model belongs to air cleaning system, is specifically related to a kind of wall-hanging PM2.5 air cleaning processor.
Background technology
PM2.5 refers to that diameter is less than or equal to 2.5 microns particle in the atmosphere, is also referred to as to enter the lung particle.Because particle diameter is little, be rich in a large amount of poisonous and harmful substances, thereby larger on the impact of health and atmosphere quality.PM2.5 represents the content of this particle in every cubic metres of air, and this value is higher, just represents air pollution more serious.
The air pollution on large-scale movement of population and gathering ground comprises physical pollution, chemical contamination and biologic contamination.Physical pollution refers to because of physical factor, such as electromagnetic radiation, noise, vibration, and the pollution that causes such as inappropriate temperature, humidity, wind speed and illumination.Chemical contamination refers to because of chemical substance, the pollution that causes such as formaldehyde, benzene homologues, ammonia and suspended particulate substance etc.Biologic contamination refers to because of the biological pollution factor, mainly comprises the pollution that bacterium, fungi, pollen, virus, organism organic principle etc. cause.The indoor air pollutants kind is a lot, usually, can be divided into suspended particulate substance and gaseous contaminant two large classes by its existence.The former refers to be suspended in airborne solids and liquid particle, comprises inorganic and organic particulate matter, microorganism and biological colloidal sol etc.; The latter is the pollutant that exists with molecular state, comprises inorganic, organic compound and radioactive substance etc.Wherein, the PM2.5 particle is because particle diameter is little, be very easy to carry the poisonous and harmful substances such as a large amount of bacteriums, virus, and the aerial time of staying is long, fed distance is far away, can directly enter bronchus after being inhaled into human body, disturb the gas exchange of lung, cause the disease that comprises the aspects such as asthma, bronchitis and cardiovascular disease, also can enter blood by bronchus and alveolar, the pernicious gases such as bacterium wherein, virus, heavy metal etc. are dissolved in the blood, and be larger to the injury of health.In addition, the PM2.5 particle also can cause environment and have a strong impact on.Because the particulate sinking speed in the particle below 1 micron is slow, RT is of a specified duration in atmosphere, can be blown into far place under large Aerodynamic force action.So the pollution of particle often involves very large zone, even becomes global problem.Particle diameter is at 0.1～1 micron particle, and is close with visible light wavelength, and visible light is had very strong scattering process.This is the main cause that causes atmospheric visibility to reduce.The sulfuric acid and the nitric acid particulate that are generated by sulfur dioxide and nitrogen oxide chemical conversion are the main causes that causes acid rain.A large amount of particles drops on affects plant growth on the plant leaf, drop on can rise on building and the clothes to stain and corrosiveness.A large amount of particle in the atmosphere disturbs the radiation on the sun and ground, thereby provincialism even global weather is made a difference.
As large-scale movement of population and the type areies such as the subway station of assembling ground, high ferro Waiting Lounge, airport building, tunnel, compartment, hospital, historical relic's protection, museum, library, exhibition center, the Art Museum; the quality of these local air qualities is directly connected to the healthy of related personnel.At present, the universalness of central air-conditioning in indoor construction, the improvement that the not tight air-conditioning system of science, operational management not only is helpless to indoor air environment is owed in some designs, also may become generating source and the route of transmission of indoor air pollutants.At first, because central air-conditioning a large amount of uses in public places, air-conditioned room forms room air pollution because the unreasonable aerosol pollutant (particulate, bacterium, virus) that causes of air current composition gathers at local dead angle; Second, air in the air-conditioning system collecting chamber, again air is sent back to after treatment indoorly, in this process, might promptly be diffused into other room to the pollutant of indivedual air-conditioned rooms and air-conditioning system itself, thereby make air-conditioning system become the medium of propagation, diffuse pollution thing.Studies show that IAQ and building ventilation air-conditioning system have much relations, if ventilation and air conditioning system design, operation or mismanagement will become pollution sources and pollute room air, be detrimental to health.The American Studies man analysis air pollution problem inside rooms in the building of building more than 1000, find it is the air conditioning system for building poor filtration effect more than 50%, Canada environmental sanitation fabric study finds: human 68% disease is owing to room air pollution causes, and the incidence of disease rises year by year.China Ministry of Public Health organizes national centralized air conditioner ventilating system hygiene state of public place supervision and check in February, 2004 to April, 937 public places in Nan Chongs that more than 60 city possesses the central air conditioning facility have been inspected in the whole nation altogether by random samples, comprise hotel, megastore, supermarket, 5600 of test sample.The centralized air ventilation system that wherein belongs to severe contamination has 441, accounts for 47.1% of sampling observation sum, and 438 of medium pollutions account for sampling observation sum 46.7%, qualified 58, accounts for 6.2% of sampling observation sum.Beijing Municipal Health Bureau also spot-check the central air-conditioning sanitary condition of Beijing 80 public places in Nan Chongs in 2004, and check result 90% belongs to severe contamination.
Therefore, wall-hanging PM2.5 air cleaning processor is in large-scale movement of population and assemble local application, can blow pure and fresh " natural wind " for this place on the one hand, allow people that the living environment of a fresh cleaning is arranged, can reduce on the other hand because of the exceed standard generation of the group public health event that causes of airborne bacterium, microorganism, timely decomposing harmful substances, conveying fresh air, reduce the secondary injury that the condition of a disaster causes people, for the safety of public place provides powerful guarantee, has very important meaning and value to making up civilized harmonious society.
At present, people only carry out physical dilution by ventilation etc. for large-scale movement of population and the toxic and harmfuls such as PM2.5 level dust, bacterium, motor-vehicle tail-gas (waste gas), ozone, VOC of assembling ground, fundamentally do not solve purifying problem.
