空气净化消毒器净化消毒性能试验研究

Experimental studies on cleansing and disinfecting characteristics of the air clean-disinfector

为开发新的室内空气净化、消毒和灭菌设备,在简要介绍空气净化消毒器基本结构和原理的基础上,研究了空气净化消毒器的空气净化性能、自然菌消亡率、高效滤床远红外辐射温升特性和远红外热力消毒特性.试验结果表明,空气净化消毒器在容积为54 m3的房间内运行90 m in后,室内空气洁净度可达M6.5级(十万级)以上,对室内空气中自然菌的消亡率达97%以上,净化后平均菌落数<200 cfu/m2,远红外热力消毒对自然菌的杀灭对数值都>1,上述指标不仅满足居室环境使用要求,而且满足II类病房使用要求.

In order to develop a new plant with functions of indoor air cleaning, disinfecting and killing bacteria, air cleaning performance of an air clean-disinfector, its killing ratio of nature bacteria, temperature rising characteristics of the filter heated by far-infrared irradiation and far-infrared disinfection characteristics have been investigated by experiments, which is based on presentation of the structure and principle of the air clean-disinfector. In the experiments, place the air clean-disinfector in a volume of 54 m^3 room and run it, then test above performance indexes one time every 30 minutes. After running 90 minutes, some stable performance indexes have tested as followings： Indoor air cleanness is over M6. 5 （100,000）, killing ratio of nature bacteria over 97% , average number of colony after cleaning less than 200 cfu/m^2 , and killing logarithm value of nature bacteria is all over 1. Above indexes meet the requirements of class Ⅱ sickroom.
