Description
Technical field
The present invention relates to a kind of energy-efficient air cleaning unit, belong to Building Indoor Environment air purification field, particularly relate to a kind of energy-efficient air cleaning unit removing fine particle.
Background technology
According to the recent statistics data of Chinese Ministry of Environmental Protection at its Web realease, the first half of this year, the air quality number of days not up to standard in 74 cities such as China's Jing-jin-ji region, the Yangtze River Delta, region, Pearl River Delta and municipality directly under the Central Government, provincial capital and cities specifically designated in the state plan has almost accounted for half, and wherein the pollution of Beijing-tianjin-hebei Region is the most serious, " serious pollution " number of days is up to 26%, and arch-criminal is exactly fine particle PM2.5.Usually, because heat supply in winter coal consumption sharply increases, urban air-quality is seriously polluted, gray haze sky takes place frequently; But after unexpectedly entering summer this year, the concentration of the pollutant such as PM2.5, ozone is still higher, June, the air quality in 74 cities just had within 1 day, exceed standard in every 3 days, and wherein, Beijing-tianjin-hebei Region serious pollution is secondary to 21.2% to go up to the sky.
Atmosphere pollution serious problems, particularly fine particle PM2.5 concentration over-standard serious problems have become the environmental problem that the public shows great attention to.The essence of atmosphere pollution is that Economic Development Mode, the industrial structure and energy resource structure are unreasonable, multiple pollutant concentrates a large amount of discharge, urban transportation is fast-developing, motor-vehicle tail-gas discharges in a large number, and long term accumulation is to the inevitable outcome of certain phase, and it is reflected as the severe overweight of PM2.5 concentration.PM10 and PM2.5 is the description to Atmospheric Grains size, and existing research confirms, the less health hazard to people of Atmospheric particulates may be larger.Therefore gray haze pollution and PM2.5 are not only environmental problem, economic problems and public health problem especially.
The impact of atmosphere pollution serious harm architecture indoor health.The experimental results shows, when atmosphere pollution is serious, there is close correlation between indoor and outdoor particle concentration level, and indoor accelerated test change in concentration major part is caused by outdoor, and namely outdoor particle is the main source of indoor pollution.In addition, for the large public building (such as, the building such as office building, hotel (hotel), shop, hospital) of densely populated place, in order to ensure the O of human body necessity
2and ventilated environment, utilize air conditioning system to be ventilation modes that current large public building generally adopts by outdoor Leads to new breeze indoor.At present, the air conditioning system that public building adopts in a large number, is normally drawn outdoor by air-treatment unit and gets new wind, after one-level slightly imitates filtration, mix with the return air from indoor, again through one-level medium air filtration, then delivers to indoor after cold/heat treatment.Regular air process unit is one multi-functional section of combination, be illustrated in figure 1 each functional section schematic diagram of regular air process unit, air-treatment unit comprises wind inlet section, slightly imitates fillter section, medium efficiency filtration section, fan section, cooling section/bringing-up section, again hot arc, humidifier section, wind outlet section; In this air handling process, although have thick effect, middle effect two-stage air cleaner to filter the particle (comprising the particle from indoor return air) of being swept along by the new wind in outdoor, thick, the middle effect air cleaner that existing market is sold is all lower to the filter efficiency of fine particle PM2.5; The such as haze weather when atmosphere pollution is serious, existing air conditioning system is while the outdoor new wind of introducing, in outside atmosphere, PM2.5 also enters air-conditioned room thereupon, and air-conditioner set becomes propagations, spreads the medium of PM2.5 pollutant.
In order to tackle haze weather, guarantee to introduce the air quality of indoor fresh air, the counter-measure that current civil buildings adopt is in air-treatment unit, set up the higher high-medium efficient of efficiency or inferior high-efficient air filter.But because the filter efficiency of air cleaner is higher, the air drag of unit increases thereupon, cause that the air-treatment amount of air-treatment unit declines, units consumption rises.Obviously, in outdoor in the good situation of air quality, also allow for a long time high-medium efficient or inferior high-efficient air filter in running order, be both unfavorable for that air conditioning system was energy-conservation, also caused the unnecessary waste of operating cost and resource.For this reason through research and development, test and improvement, the present invention proposes the energy-efficient air cleaning unit that one can remove fine particle (PM2.5, PM10), this device can be applicable to and can be used in other air cleaning system on centralized air ventilation system, also, to improve the fine particles such as system reply outside atmosphere seriously polluted weather PM2.5, PM10 to the defence capability of indoor air environment pollution effect.
Summary of the invention
The object of this invention is to provide a kind of energy-efficient air cleaning unit removing fine particle, it comprise be arranged in order wind inlet section, initial effect filtering section, medium efficiency filtration section, PM2.5 purification function section to be opened/closed, fan section, cooling section/heater segment, again hot arc, humidifier section, wind outlet section; Wherein PM2.5 purification function section to be opened/closed comprises support body, high-medium efficient or inferior high-efficient air filter, turning cylinder, and after being arranged on medium efficiency filtration section; Support body comprises Vertical Square framework, high-medium efficient or inferior high-efficient air filter carrier, high-medium efficient or inferior high-efficient air filter fixed mount; High-medium efficient or sub-highly effective air air cleaner are arranged on high-medium efficient or inferior high-efficient air filter fixed mount; High-medium efficient or inferior high-efficient air filter fixed mount are arranged on high-medium efficient or inferior high-efficient air filter carrier; High-medium efficient or inferior high-efficient air filter fixed mount and high-medium efficient or inferior high-efficient air filter carrier can rotate the rotation that moving axis realizes within the scope of 90 °; Vertical Square framework is fixed in the frame of air processing machine together with turning cylinder; Vertical Square framework and high-medium efficient or inferior high-efficient air filter carrier can realize cooperatively interacting; What drive high-medium efficient or inferior high-efficient air filter carrier to rotate moving axis rotation is actuating unit; PM2.5 purification function section to be opened/closed can by the control of intelligent robot control system(RCS) realization to mode of operation; This device can according to the size adjustment method of operation of PM2.5 fine particle concentration in indoor-outdoor air, under the prerequisite effectively ensureing to send into IAQ, the long-life of the energy-saving run and high-medium efficient or inferior high-efficient air filter that realize blower fan system is run.
