Description
Technical field
The utility model belongs to harmful gas eliminator, is specifically related to a kind of purification of air processor.
Background technology
PM2.5, refers to that in air, diameter is less than or equal to the particle of 2.5 microns, also referred to as entering lung particle.Because particle diameter is little, be rich in a large amount of poisonous and harmful substances, thus 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.In addition, in the manufacture process of the application of industrial part, the coating of sheet material etc., also can produce the harmful exhaust containing meta-acid or meta-alkali, molecule, bad smell, these waste gas are sometimes unprocessed to be also disposed in air.
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, as electromagnetic radiation, noise, vibration, and the pollution that inappropriate temperature, humidity, wind speed and illumination etc. cause.Chemical contamination refers to because of chemical substance, as the pollution that formaldehyde, benzene homologues, ammonia and suspended particulate substance etc. cause.Biologic contamination refers to because of the biological pollution factor, mainly comprises the pollution that bacterium, fungi, pollen, virus, organism organic principle etc. cause.Indoor air pollutants kind is a lot, usually, can be divided into suspended particulate substance and the large class of gaseous contaminant two by its existence.The former refers to suspend aerial solids and liquid particle, comprises inorganic and organic particulate matter, microorganism and biological colloidal sol etc.; The latter is the pollutant existed with molecular state, comprises inorganic, organic compound and radioactive substance etc.Wherein, PM2.5 particle due to particle diameter 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, directly bronchus can be entered after being inhaled into human body, the gas exchanges of interference lung, cause the disease comprising the aspects such as asthma, bronchitis and cardiovascular disease, also blood can be entered by bronchus and alveolar, pernicious gas, the heavy metals etc. such as bacterium wherein, virus dissolve in blood, larger to the injury of health.In addition, PM2.5 particle also can cause environment and have a strong impact on.Because the microparticles settle speed of less than 1 micron is slow in particle, RT is of a specified duration in an atmosphere, can be blown into far place under large Aerodynamic force action.So the pollution of particle often involves very large regions, even become global problem.Particle diameter is at the particle of 0.1 ~ 1 micron, close with the wavelength of visible ray, has very strong scattering process to visible ray.This is the main cause causing atmospheric visibility to reduce.The sulfuric acid generated by sulfur dioxide and nitrogen oxide chemical conversion and nitric acid particulate are the main causes causing acid rain.A large amount of particles drops on plant leaf affects plant growth, drops on building and clothes and can play contamination and corrosiveness.Particles a large amount of in air, the radiation on the interference sun and ground, thus the weather even global to provincialism makes a difference.
As large-scale movement of population and the type area such as subway station, high ferro Waiting Lounge, airport building, tunnel, compartment, hospital, historical relic's protection, museum, library, exhibition center, the Art Museum of assembling ground; 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 the construction of indoor, the improvement that the not tight air-conditioning system of science, operational management is not only helpless to indoor air environment is owed in some designs, also may become occurring source and the route of transmission of indoor air pollutants.First, due to central air-conditioning a large amount of uses in public places, air-conditioned room causes aerosol pollutant (particulate, bacterium, virus) to gather at dead angle, local because air current composition is unreasonable, forms room air pollution; Second, air in air-conditioning system collecting chamber, again air is sent back to indoor after treatment, likely the pollutant of indivedual air-conditioned room and air-conditioning system itself is promptly diffused into other room in this process, thus make air-conditioning system become the medium of propagation, diffuse pollution thing.Research shows 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.Air pollution problem inside rooms in American Studies People Analysis building more than 1000 building, find that more than 50% is air conditioning system for building poor filtration effect, environmental sanitation fabric study of Canada finds: the disease of the mankind 68% causes due to room air pollution, and the incidence of disease rises year by year.The Ministry of Public Health of China 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 central air conditioning facility have been inspected in the whole nation altogether by random samples, comprise hotel, megastore, supermarket, detect 5600, sample.The centralized air ventilation system wherein belonging to severe contamination has 441, accounts for 47.1% of sampling observation sum, medium pollution 438, accounts for sampling observation sum 46.7%, qualified 58, accounts for 6.2% of sampling observation sum.Beijing Municipal Health Bureau also spot-check in central air-conditioning sanitary condition to Beijing 80 public places in Nan Chong in 2004, and check result 90% belongs to severe contamination.
Therefore, purification of air 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, people are allowed to have the living environment of a fresh cleaning, can reduce on the other hand because the bacterium in air, microorganism exceed standard the generation of group public health event of initiation, 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, to structure, civilized harmonious society has very important meaning and value.
At present, people carry out physical dilution for the toxic and harmful such as PM2.5 level dust, bacterium, motor-vehicle tail-gas, ozone, VOC on large-scale movement of population and gathering ground only by ventilation etc., fundamentally do not solve purifying problem.
