At present, the filter cleaning is mainly moved to the cleaning room in plastic bags for cleaning, manual or ultrasonic cleaning. In situ cleaning refers to the method of moving to the cleaning room for cleaning, manual or ultrasonic cleaning. It is easy to increase the working intensity and pollution opportunity if the cleaning is not in place. A special cleaning program is designed to realize on-site cleaning of fluidized bed, which can realize on-site cleaning without dismantling any components. The cleaning time can be shortened by 3-4 hours.
When cleaning after production, each filter can be moved up and down. There is a group of nozzles on the top of the filter to spray liquid to clean the filter. Moreover, the power of spraying can drive the filter to rotate, so that every fold of the filter can be fully cleaned. A cleaning workstation for cleaning the fluidized bed and a specially designed spray for cleaning the bed and sleeve filter are necessary. The nozzle at the top of the tower sprays clean liquid into the filter to wash the filter to ensure that the filter is clean. The nozzle on the top of the tower can also move up and down to clean the rest of the fluidized bed. The nozzle at the bottom of the inlet chamber cleans the chaff sieve plate and the inlet chamber. The cleaning system can be designed to be fully automatic without manual intervention, which is convenient to verify the cleaning procedure.
