How long is the service life of a high-temperature high-efficiency filter?
How long is the service life of a high-temperature high-efficiency filter?The service life of high-temperature high-efficiency filter is affected by a variety of factors, usually about 1 to 3 years, but it needs to be combined with the following conditions:Key factors affecting service life Use environment Temperature: Long-term high temperatures (such as close to or above the design temperature upper limit) will accelerate the aging of the filter material and glue failure. Dust concentration: A high concentration of dust environment will lead to a rapid rise in filter resistance and shorten the replacement cycle. Corrosive gases: Corrosive gases in the chemical industry will accelerate the deterioration of materials. maintenance Regular cleaning/replacement: When the surface is black or the resistance increases, it is necessary to clean the non-woven fabric or replace the filter element in time. Installation tightness: Leakage will lead to excessive local filtration load and shorten the overall life. Standard operation: Avoid frequent start and stop or sudden cooling and heating, and reduce material stress damage. Product Quality High-quality filter materials (such as ultrafine glass fiber) and high-temperature glue (such as ceramic glue) are more durable. Well-known brands (such as Pall, Camfil, and Jinhai High-tech) usually pass rigorous testing and have a more stable life. Suggestions for extending service life Control operation parameter Avoid being at the limit temperature for a long time (such as a filter that is resistant to 250 ° C, it is recommended that the constant temperature be less than 260 ° C). Monitor the pressure difference regularly and replace or clean it in time. Strengthen routine maintenance Check the wind speed and tightness 1-2 times a year to ensure even airflow. When replacing, choose the same specification model to avoid filter paper damage. Optimized usage scenario In an environment of high dust concentration, the primary or medium effect filter can be pre-installed to extend the life of the main filter. Slow cooling during shutdown to reduce the impact of thermal stress on the structure. Sum up The life of high high-temperature efficiency filter needs to be dynamically evaluated according to specific working conditions. Reasonable maintenance and standardized use can significantly extend its efficiency, otherwise it may be shortened to 1 year or even less. You are advised to adjust maintenance policies based on the pressure difference alarm or wind speed attenuation. |
