FRI and FKI-type bag filters are designed for efficient suspended particles trapping from gases and aspiration air, which are not toxic, inflammable or explosive. Bag filters are used in various sectors of industry: ferrous and non-ferrous metallurgy, power generation industry, construction material fabrication, textile and food industry. Electrostatic precipitators’ operating principle consists in impacting trapped dust particles on the filter area. Formed dust layer is periodically removed from the filtering elements. Regeneration periodicity is chosen individually, subject to the required purification rate, physical and chemical properties of the dust to be trapped and filtering material endurance.
Advantages of cloth filters
- Efficient operation in almost all industrial processes;
- Stable and efficient particles trapping, including those less than 1 micron in size;
- Efficient when electrostatic precipitators do not provide for high purification rate, especially if gas humidity is low, etc.;
- Low capital costs of construction as compared with electrostatic precipitator installation costs;
- Trapped material remains in its original state;
- Easy maintenance and repair.
Bag filter design types
FRI-type bag filters are rectangular-body devices. Dust-laden flow passes through the filtering cloth, put on a wire frame, in the outside-in direction. Regeneration is performed by compressed air impulses, without shutting the blocks down. A device, specially developed for this purpose, is used as a regeneration control unit.
Delivery set
- Bag filter body with regeneration units;
- A set of filtering bags (cloth type is specified separately);
- Filter regeneration control device.
