Description
Technical field
The utility model relates to a kind of purifier, particularly relates to a kind of air cleaning unit.
Background technology
China's atmosphere pollution is serious day by day, worsen urban area especially big city air quality, it is high particularly can to go into lung particle PM2.5 and content of harmful gas in the air, developing country's air quality index than World Health Organization's suggestion doubles even several times, China's City Building IAQ go fromes bad to worse especially, serious harm broad masses of the people's life and health.
Mainly containing harmful substances in the air is: PM2.5, nitrogen oxide (NOx), oxysulfide (SOx), carbon monoxide (CO), ozone (O3), volatile organic matter VOCs etc.
IAQ and room air pollution control now is subject to people's attention day by day with improvement, and its main cause is:
(1) people's every day nearly 85-90% time spend indoor, the air of breathing mainly directly comes from indoor, the chance that contacts with indoor pollutant and time are far more than outdoor;
(2) source of indoor pollutant and kind increase day by day, cause the degree of room air pollution to increase the weight of more on the basis that outside atmosphere is polluted;
(3) for energy savings, modern architecture closure degree increases, because its central air conditioner system ventilation facility imperfection, it is outdoor to cause indoor pollutant in time not discharge, and causes IAQ to worsen.
At present, the general indoor air purification technology that adopts is generally:
(1) filtration method, this method can only filter out bulky grain thing in the air, and can not remove harmful substances such as airborne volatile organic matter, nitrogen oxide, oxysulfide, carbon monoxide;
(2) absorption method, this method is mainly utilized porous sorbing material such as porous silica, active carbon, activated alumina, pottery or zeolite are removed harmful substances in air absorption, but this method needs different sorbing materials at different harmful substances usually, therefore it is bigger to realize that truly room air purifies difficulty comprehensively, though acticarbon can adsorb most harmful substance, but because its adsorbance is limited, adsorbent needs frequent regeneration, particularly active carbon has the possibility of spontaneous combustion more than 573K, cause sizable difficulty to regeneration, limited its application.
(3) photocatalytic oxidation, this method is to utilize the photocatalytic activity of catalyst, make the VOCs that is adsorbed on the catalytic media surface that redox reaction take place, finally be converted into carbon dioxide, water and inorganic molecules material, because cheap two wide material sources of TiO2, to the uv absorption rate height, anti-photoetch, chemical stability and catalytic activity height, and there is not toxicity, a lot of organic matters there is strong suction-operated, thereby become the most frequently used photochemical catalyst, and the major advantage of photocatalytic oxidation is: the capacity usage ratio height, operate at normal temperatures usually, no coupling product forms, catalyst after the use can be with recycling after physics and the chemical method regeneration, and the volatile organic matter but this method can only be degraded can't be removed harmful substances such as nitrogen oxide and oxysulfide.
