FILTER CLEANING SYSTEM WITH DUST COLLECTOR
The filter cleaning system comprises filter plenum, dust collector and blower. The dust collector is of Pulse Jet Type whereby the cleaning is done automatically by compressed air through a timer and solenoid valve. The filters shall be Cartridge type made out of spun bound Polyester with anti-adhesive finish.
The system is designed to clean filters viz AHU panel filters and cartridge filters. The filter can be cleaned by using water/compressed air. The filter is placed in the filter plenum with the dirty side facing downwards. Air/water is injected from the top of the filter. The dust being on the reverse side of the filter gets sucked by the blower into the scrubber. The dust is removed in the scrubber.
The system is designed to clean 1no. filter of maximum size 610 x 610 x 300mm deep at a time.
The filter is placed on the filter plenum and is manually cleaned with compressed air gun. The dirty side of the filter is placed downwards. As the compressed air is injected from the top through an air gun the particulate matter is sucked from the bottom and conveyed to a dry scrubber. Thus, the filter is cleaned. THIS IS NOT SUITABLE FOR WET CLEANING.
FILTER CLEANING SYSTEM WITH SCRUBBER
The system in general shall comprise of Filter plenum, ducting, Venturi scrubber, blower, pump and water recirculation piping etc. The dust laden air is sucked by a blower located after the scrubber and conveyed to the scrubber through ducting. This air is scrubbed using water as the scrubbing media. The scrubbed water is collected in the bottom recirculation tank which has to be drained periodically. The clean air with dust concentration of less than 30 mg/nm3 is discharged into the atmosphere through a stack.
