Feature of Pleated filter bag
As below are the outstanding technical advantages for AD bag filter on the alternation of traditional bag house dust collector :
it can directly replace current filter bag sleeves and filter cages without the alternation of main body structure of dust collector, and by 50%~150~% filtering area will be increased.
It can dramatically reduce the ratio of system pressure so that performance and working life of the entire system will be both improved.
It can greatly reduce the frequency of cleaning and longer-lasting the interval of deducting.
Because of its special fold structure, making the efficiency of pulse cleaning significantly improved
The increase of filtering area of bag house dust collector make air flow rate declining , greatly optimizing the on-line dedusting effect;
With both special structural design of AD bag and filter cage,greatly decrease the damage from pulse jet and dust skeleton of the special design, greatly reduced fatigue damage caused by pulse jet and and intermittent emissions;
The filter cage supporting ring lays inside steel bars, and effectively increase the contact area , completely avoid the direct impact on the dust filter bag;
According to the need to increase the filter area at the same time, shorten the length of dust bag, and optimize the system operation;
Greatly reduce the amount of compressed air and air compressor, and pulse valve load; Fan load greatly reduced, the system significantly reduced energy consumption;
Applicable working conditions of Pleated filter bag
The original equipment design is unreasonable, large fan, dust filter area is small, large pressure, air volume is small, high dust discharge conditions
The discharge is not up to standard, the production needs to increase the processing air volume, the original equipment filter area is small, the replacement of the new dust collector high cost situation.
The site space is limited, the dust collector volume can not meet the large amount of air volume, but in the same filter area conditions, the use of AD bag dust collector volume is 60% of the volume of bag filter sleeves.
Applicable industries of pleated filter bag:
Petrochemical, chemical, plastics, electricity, food, pharmaceutical, grain processing, casting, steel, nonferrous metals, cement, mining and other industries
