Technical field

The present invention relates to the technical field of filtration and cleaning, and specifically to a movable paper filter element cleaner and a cleaning method thereof.

Background technique

The filter element is the core part of the filter element filtration equipment. The current way to clean the paper filter element is to use the backflush function of the filter element itself, and use compressed air to drain the filter residue on the paper filter element together with the filtrate. For example, the invention with application number 201811134702.3 discloses a self-cleaning air filter. A main filter element is provided in the air filter housing, an air inlet is provided on the side of the housing, and an air outlet is provided on the upper end of the housing. The pressure air source passes through the tube. The solenoid valve is connected to the safety filter element through the pipeline, and an ash discharge port is provided at the bottom of the shell. The pressure airflow passes through the solenoid valve and then blows back into the safety filter element. The backflush causes the air fluid to instantly generate a strong pressure difference on the inner and outer surfaces of the filter element, forcing the dust and pollutant particles to be scattered and stripped from the outer surface of the filter element. Under the action of the air flow field Exhaust from the air inlet or ash discharge port.

However, compressed air cannot completely remove the filter residue between the paper filter elements. If the cleaning is not thorough, the filtration capacity of the filter element will be greatly reduced after cleaning. And as the use time increases, the filtration capacity of the filter element will seriously attenuate; once the filter element is completely blocked, The online backflushing method will lose its effect and the filter element needs to be completely replaced, resulting in a waste of manpower and material resources.
