Abstract

The invention discloses a method for determining the purifying performance of an air purifying material and belongs to the field of air purification. The method is used for a device for determining the purifying performance of an air purifying material. The determining device comprises an outer cabin, wherein the outer cabin is provided with a first outer cabin airflow inlet and a first outer cabin airflow outlet. The method comprises the steps that 1, the air purifying material is put in the determining device; 2, polluted gas is led from the first outer cabin airflow inlet, wherein the concentration of the polluted gas is Cin; 3, the concentration Cout of the polluted gas is determined at the first outer cabin airflow outlet in real time, and the determining time t is recorded; 4, the polluted gas purifying efficiency eta of the air purifying material at the moment t is calculated, as shown in a formula (I). The purifying efficiencies of multiple types of polluted gas of multiple air purifying materials can be determined, and determining results are more accurate.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a method for measuring the purification performance of an air purification material. Background technique [0002] At present, the global environment is deteriorating day by day, and it is an indisputable fact that the air pollution in many cities in my country, including Beijing, is becoming more and more serious. In particular, the recent continuous large-scale haze weather has further promoted people's concerns about air quality. At the same time, people's excessive decoration of the living room environment will cause a large amount of volatile organic compounds (total volatile organic compounds, Total Volatile Organic Compounds, TVOC) such as formaldehyde, benzene, toluene and ammonia to be emitted during the construction process, causing indoor air pollution on the one hand. On the one hand, photochemical reactions occur with NOx (nitrogen oxides) under the action of light, ...
