BAG FILTER IS A DEVICE WHICH HELPS TO SEPARATE DUST PARTICLES FROM RAW GAS EFFICIENTLY.
BAG FILTER USED IN DIFFERENT AREAS LIKE:
#DRYGASCLEANING PLANT, WHERE DUST SEPARATED FROM RAW GAS IN BLAST FURNACE.
#PCI WHERE COAL POWDER SEPARATED FROM WASTE GAS.
#CASTHOUSE AND #STOCKHOUSE #DEDUSTINGSYSTEM WHERE
DUST IS SEPARATED FROM AIR.
BAG FILTER CONSISTS OF
NUMBER OF CHAMBERS TO HOLD ALL RAW AND CLEANED GAS INSIDE
SERIES OF BAGS WITH CAGE TO SEPARATE DUST FROM GAS
#PULSINGSYSTEM TO CLEAN THE BAGS TIME TO TIME
INLET OUTLET DUCT AND ISOLATION VALVE FOR TAKING CHAMBER ONLINE OR OFFLINE
#DUST COLLECTING AND TRANSPORTING SYSTEM TO MAKE THE SYSTEM READY FOR FURTHER PROCESS
#BLEEDERVALVE TO RELEASE EXCESS PRESSURE IF ANY
#HIGHPRESSURE SAFETY DEVICE - EXPLOSION HATCH TO AVOID EXCESSIVE DAMAGE ON THE SYSTEM
ONLINE HIGH TEMPERATURE MEASURING DEVICE TO AVOID DAMAGE DUE TO HIGH TEMPERATURE
ONLINE HIGH DUST LEVEL MEASURING SYSTEM TO IDENTIFY IF DUST LEVEL GOES HIGH
CLEAN GAS OUTLET DUCT WITH HIGH DUST CONCENTRATION DEVICE (OPACITY METER) TO IDENTIFY THE LEAKAGE IN BAGS AND DUST EMISSION (AS PER ENVIRONMENTAL NORMS).
RAW GAS ENTERS THROUGH THE INLET DUCT OF BAG FILTER CHAMBER AND PASSES THROUGH THE BAGS AND CLEANED GAS FINALLY WENT OUT FROM OUTLET DUCT TO THE SYSTEM.
HERE BAGS ARE DESIGNED SO THAT DUST CAN NOT PASS THROUGH THE BAGS, BUT GAS CAN PASS THE BAGS.
DURING RUNNING PROCESS, DUST GET STICKED OUTSIDE THE BAGS AND
DURING PULSING DUST GETS LOOSENED FROM THE BAGS AND FELL DOWN INTO HOPPER BOTTOM CONE. FROM THERE DUST TRANSPORTED THROUGH CHAIN CONVEYOR AND FINALLY SENT TO SINTER PLANT FOR MIXING WITH IRON FINES TO MAKE SINTER.
IN THIS TYPE OF BAG FILTER, RAW OR WASTE GAS CAME THROUGH THE INLET DUCT. IT ENTERS INTO THE HOPPER, MOVING UPWARDS TOWARDS BAG FILTER. DUST OR COAL CARRYING AIR OR WASTE GAS PENETRATE THROUGH THE PORES OF BAGS BUT COAL OR DUST PARTICLES CAN NOT PASSES THROUGH AND STICKED TO THE OUTER PART OF BAGS.
CLEAN AIR OR GAS REACH TO THE CLEAN GAS CHAMBER. TUBE SHEET IS A PARTITION BETWEEN RAW INLET GAS AND OUTLET CLEAN GAS. DEFLECTOR PLATE PROTECT BAGS FROM KINETIC MOVEMENT OF THE INCOMING RAW GAS
DURING PULSING, COAL OR DUST PARTICLES BLOWN AND SETTLED IN THE HOPPER BOTTOM PART AND FROM THERE, COAL OR DUST DISCHARGED.
CLEAN GAS CAME INTO THE CLEAN GAS CHAMBER AND THROUGH OUTLET CLEAN GAS DUCT , IT MOVES TOWARDS CHIMNEY OR STACK BY THE ACTION OF INDUCED DRAFT FAN (I D FAN).
