Problems solved by technology
This process leads to (1) the deviation of the life test of the purification components, especially the physical adsorption purifier at high concentration, and the greater the deviation of the life test of the purifier with the smaller amount of physical adsorption; (2), the purification efficiency test appears Bias, the process from the initial state of the component to the steady state cannot be accurately described
Therefore, the test results in the actual test are not accurate, and the test results cannot be effectively applied to design and operation management

The invention relates to a method and a device for testing the primary purification efficiency of an air purification component, and the test device comprises the air purification component and a pollutant generator which are connected in sequence, a test channel comprising an upstream valve and a downstream valve which are respectively arranged at two sides of the air purification component, anda by-pass channel with a by-pass valve connected on the test channel in parallel, wherein the junctions of the by-pass channel and the test channel are respectively arranged at the outside of the upstream valve and the downstream valve. When in a test, adjusting the flow and humiture values to set values, opening the by-pass valve and closing the upstream valve and the downstream valve; and opening the pollutant generator, adjusting pollutant concentration to reach the designated concentration, closing the by-pass valve, opening the upstream valve and the downstream valve, and starting the test. The invention avoids the problem that pollutant enters into a member to be tested during the period of adjusting the pollutant concentration, thus ensuring the accuracy of the purification efficiency and purification service life.
Description
technical field [0001] The invention relates to a performance test of an air purification component, in particular to a primary purification efficiency test of chemical pollutants and microbial pollutants of the air purification component. Background technique [0002] Indoor air quality greatly affects people's quality of life, health and work efficiency. Since people spend more than 85% of their time indoors, indoor air pollution triggers the following three diseases: Sick Building Syndrome (SBS), which is related to buildings disease (BRI), multiple chemical pollutant allergy (MCS). According to the statistics of the U.S. Environmental Protection Agency (EPA), the annual economic loss caused by poor indoor air quality in the United States is as high as 40 billion U.S. dollars. In my country alone, in 1995, the economic loss caused by indoor air pollution that endangers health is estimated to be as high as 10.6 billion U.S. dollars according to the value of willingness to ...
