Air purification filtering material testing experimental system

Abstract

The invention discloses an air purification filtering material testing experimental system which comprises an air compressor, a silica gel drying pipe, a particle matter filter and an active carbon absorption filter which are connected together through a pipeline in sequence, wherein the input end of the air compressor is connected with an air intake pipeline; the output end of the active carbon absorption filter is connected with a first mass flow controller and a second mass flow controller respectively through pipelines; the output end of the first mass flow controller is connected with a humidity control unit through the pipeline; the output end of the second mass flow controller is connected with a pollutant generating unit through the pipeline; the output ends of the humidity control unit and the pollutant generating unit are respectively connected with an input port of a mixing bottle through the pipelines; and an output port of the mixing bottle is connected with a filtering material testing unit through the pipeline. With the adoption of the air purification filtering material testing experimental system, the switchover of single channel testing clamps of different specifications is realized, the synchronous measurement on a plurality of samples is also realized; and the control precision (of a testing working situation) which is provided by relevant internal standards can be realized.

Description

technical field [0001] The invention relates to a filter material testing system. In particular, it relates to an air purification filter material testing experimental system. Background technique [0002] The problem of indoor air pollution in buildings is a problem that urban residents in our country generally face and pay attention to. Indoor air pollutants can be divided into particulate pollutants, gaseous pollutants and bioaerosol pollutants. For civil buildings, especially newly renovated buildings, the problem of gaseous pollutants is even more serious. The use of building materials and various indoor daily necessities is the main source of indoor gaseous pollutants. The harmful gases released are mainly volatile organic compounds (Volatile Organic Compounds, VOCs for short), including benzene, toluene, and formaldehyde. [0003] Volatile organic compounds are extremely harmful to the human body. Taking formaldehyde as an example, long-term inhalation can lead to ...
