To conquer the disadvantages of weak cohesive, poor folding resistance of the glass fiber felt, ZONEL developed fiber glass blended needle felt(similar to FMS needle felt or FMS filter bag), these fiber glass nonwoven filter materials already with the long time testing, nowadays are widely used for many applications, such as cement, metallurgy, mining, chemical, thermal power plants, etc.
When the pulse jet bag filter house operates, the dust air always comes from outside of the filter bags and the purified air will pass through the filter bags and then exhaust into the atmosphere, during that time bag filter house always with a positive or negative pressure, so a filter bag cage will be put inside of the filter bag to anti-collapse.
The filter cage also called dust collector filter cage or filter bag frame, can be made of galvanized steel, carbon steel with silicon coating, SS 304 or SS316, titanium, and so on for different working conditions.
The filter bag support cage was combined with vertical wires, supporting cages, top caps, and bottom caps, as well as the venturi. To reduce the filter bags’ touch with the supporting rings of the bag supporting cage, we developed the star-shaped side view dust collector filter bag cage; to increase the filter area, we developed the pleated filter bags with the relevant pleated filter bag cages.
