Description

Air purification filter material test experimental system

technical field

The utility model relates to a filter material testing system. In particular, it relates to an air purification filter material testing experimental system. the

Background technique

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, referred to as VOCs), including benzene, toluene, and formaldehyde. the

Volatile organic compounds are extremely harmful to the human body. Taking formaldehyde as an example, long-term inhalation can lead to an increase in chronic respiratory diseases. Symptoms of poisoning include headache, weakness, anxiety, dizziness, and decreased nervous system function. According to the data of relevant departments, the annual death toll caused by decoration pollution has reached 111,000, and there are about 304 people every day. Due to the great harm to human health, on June 15, 2004, the World Health Organization issued the No. 153 "Formaldehyde Carcinogenic" Bulletin, officially confirming that formaldehyde has a carcinogenic effect on the human body. There is sufficient evidence to prove that formaldehyde can cause human diseases. Nasopharyngeal cancer and sinus cancer; In addition, formaldehyde is likely to cause leukemia. the

For the removal of gaseous volatile organic compounds (VOCs), the main technologies that have been developed at home and abroad include porous media adsorption, thermal catalytic oxidation, photocatalytic oxidation, ozone oxidation, negative ion technology, etc. Photocatalytic oxidation, ozone oxidation and negative ion technologies have been proven to easily produce secondary pollutants; porous media (such as activated carbon) adsorption, thermal catalytic oxidation technology has become a focus of attention due to its stability, safety and service life. At present, my country's air purifier industry is developing rapidly. During the "Eleventh Five-Year Plan" period, the average annual growth rate of my country's air purifier sales has reached 27%, but the products are mixed and lack authoritative, unified and reliable quality certification. my country's current standards, such as "Air Purifier" (GB/T18801-2002), are directly translated from abroad and have certain limitations. This standard only requires the detection of the purification effect within 1 hour or even less in the test, and the effect of many filter materials will be greatly attenuated with use, and the temperature and humidity of the product in actual use are also different from those of the test. It is not consistent under the room conditions, which makes it possible to pass the test in the laboratory, but it is difficult to judge the actual use effect. the

Existing air purification test bench patents are more focused on particle purification ("A filter material online test bench" 200910234557.0; "A filter material and filter dual-purpose simple test bench" 200920255569.7, etc.) and biological aerosol purification (" Bioaerosol Filtration Efficiency Test Apparatus and Method for Filtration or Isolation Materials” 200810053511.4), in terms of purification of gaseous chemical pollutants, especially the test of filter materials for purification of gaseous pollutants, there is almost a blank in China. "Test method and device for primary purification efficiency of air purification components" 201010154729.6, "Devices and methods for indirect testing primary purification efficiency of air purification components" 201010154754.4 provide testing methods and devices for air purification components, but they are all aimed at air purification components , but cannot test the filter material. At present, the American ASHRAE standard "ANSI/ASHRAE STANDARD145.1-2008" has made corresponding regulations on the test methods and requirements of filter materials for air purification in the world, and the domestic test bench for purification filter materials that can meet international standards It is even more blank. the
