低臭氧型负离子雾霾空气净化器设计

Design of Low Ozone Anion Haze Air Purifier

降低负离子空气净化器的臭氧排放量,保护人们免受臭氧的伤害,可以在传统净化器的基础上增加紫外线除臭氧和催化剂除臭氧。臭氧很不稳定,吸收254 nm波长的紫外线后,分解为氧气。高效臭氧分解催化剂能在室温下将臭氧分解为氧。普通负离子空气净化器会释放超标的臭氧,其浓度高达205 ppb,而加入除臭氧装置的新型净化器则释放的臭氧很少,使其浓度控制在19 ppb之内。低臭氧型负离子雾霾空气净化器能有效地清除自身产生的臭氧,性能更优,适合在室内使用。

In order to reduce the concentrations of ozone from anion air purifier,and protect people from the harm of ozone,we can add another two powerful features on the basis of the traditional filter including the ultraviolet and efficient ozone decomposition catalyst to decompose ozone. Ozone is very unstable,which will be decomposed into oxygen when absorbing 254 nm wavelength ultraviolet ray. Efficient ozone decomposition catalyst can decompose the ozone into oxygen at room temperature. An ordinary anion air purifier releases excessive amount of ozone with concentration as high as 205 PPB. However,the new type air purifier with ozone decomposition function can release very little ozone,and control it within 19 PPB. The low-ozone anion haze air purifier can effectively remove its own emissions of ozone,which has a better performance and is more suitable for indoor use.
