Abstract

The invention aims to provide a testing device for an air purification material and a detection method for the purification efficiency of an air purification filter material. The testing device comprises a shell, wherein a clamping device is arranged on the inner wall of the shell; the clamping device is annularly closed, and the outer edge of the clamping device is fixedly connected with the inner wall of the shell; the clamping device divides the shell into two parts, one part is provided with a sample inlet, and the other part is provided with a discharge port; and the testing device is a closed space when the sample inlet and the discharge port are closed. The detection method comprises the steps that the air purification filter material is arranged on the clamping device; polluted gasis input into a feed port; the polluted gas and purified gas are collected, the concentration of harmful gas is detected, and the purification efficiency is calculated. The method is used for evaluating the purification capability and the purification effect of the air purification material and has the advantages that the stability is high, the system leakproofness is good, the detection data forthe purification efficiency of the air purification filter material is accurate, and the repeatability and reproducibility are very good.

Description

technical field [0001] The invention belongs to the technical field of material testing, and particularly relates to an air purification material testing device and an air purification filter material purification efficiency detection method. Background technique [0002] With the increasing improvement of people's living standards and the increasing emphasis on the quality of home decoration, everyone has further requirements for the air quality involved in life, especially with the hot discussion of the topic of smog, many families, schools, hospitals, public Places, etc. are beginning to be equipped with air purifiers. [0003] For purifier manufacturers, how to judge the purification ability of purification materials and how to choose suitable purification materials, there is no mature method and equipment in my country at present. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to provide an air purification material testing device and ...
