Methods and key points of cleaning dust bag

　　1. High frequency vibration is adopted to clean the dust bag, and the larger dust particles entering the surface of the filter bag are removed as far as possible, which will not affect the entanglement fastness of the fiber and keep the good peeling resistance of the filter bag.

　　2. Cleaning and dedusting bag chemical experiment treatment: take bag samples, use instrument test to detect the oil content of the filter bag, so as to select appropriate washing materials and clean the filter bag to a large extent without any damage to the filter bag.

　　3. Cleaning and dedusting bag cleaning: select appropriate washing materials and strictly mix them, clean with low temperature water, even water flow, moderate strength, no mechanical damage to the filter bag.

　　4. Cleaning and dedusting bag drying: hot air drying at 110 ℃ is adopted to keep the size stability of dedusting bag, and the bag will not be deformed or retracted after drying.

　　5. Cleaning and dedusting bag repair: repair the damaged filter bag due to abrasion and holes caused by use to ensure a high reuse rate.

　　6. Cleaning and dedusting bag detection: the instrument is used to detect the physical index of the cleaned filter bag to ensure that the cleaning quality meets the requirements.
