2.UTERSAir filterThe prototype air filter is a respiratory protection device that people use to protect their breathing. According to records, as early as a century of Rome, when they were purifying mercury with a mask made of burlap for a long time after that. Air filters have also made progress, but they are mainly used as respiratory protection appliances in hazardous industries such as the production of hazardous chemicals. The release of the mobile appraisal system in 1827 made people have a better understanding of the mechanism of air filtration. The rapid development of air filters is closely related to the development of the military industry and the electronics industry. In the 1950s, the United States conducted in-depth research on the production technology of glass fiber filter paper and made the air filter improved and developed. In the 1960s, HEPA filters were introduced; in the 1970s, HEPA filters with fine glass fiber filters as filter media were used. 3 micron particle size filtration efficiency up to 99.9998. Since the 1980s, with the advent of new test methods, evaluation of usage improvements and increased requirements for filtration performance, serious problems have been found with HE-PA filters, resulting in higher performance ULPA filters. At present, all countries are still working hard to study and it is estimated that a more advanced air filter will soon appear.Significant advances have also been made in the design of the filter itself, the most important of which is the removal of the partition plate, ie the development of the filter without the partition plate. The absence of a baffle filter not only eliminates the danger of the filter |
