Common cleaning principles and methods for metal sintered felt filter elements

1. Chemical cleaning
The most common cleaning solvent for metal sintered felt is acid-base cleaning solution. Chemical cleaning is a common and effective cleaning method for collecting polyester condensate filters.

2. Ultrasonic wave cleaning method
Ultrasonic wave energy is a wave energy of continuous pressurization and expansion. This energy is applied to the liquid to generate cavitation and continuous rupture, resulting in ultrasonic cleaning.

3. Heat treatment cleaning
Vacuum pyrolysis, heated flood tank, liquefied bed, and hot salt bath are some of the treatment methods that should be considered when chemical cleaning methods do not work.
The cleaned metal sintered felt is checked for bubble integrity and the pressure drop of the filter element is measured.
