Filter bag cage/ Filter bag supporting cage/ Filter bag frame
General introduction for filter bag cage/ Filter bag supporting cage/ Filter bag frame
When the pulse jet bag filter house operating, the dust air always comes from outside of the filter bags and the purified air will pass through the inner side of the filter bags then exhaust to the atmosphere, and bag filter house always with a positive or negative pressure, so in case the filter bag collapse, we always insert a metal filter bag cage into the filter bags.
The filter cage also called dust collector filter cage or filter bag frame, which can be made of galvanized steel, carbon steel with silicon coating, SS 304 or SS316, even titanium, and so on for different working conditions. And according to the filter bag shape, the bag house filter cage also can be designed with side view of round shape bag supporting cages, oval shape bag cage, etc.
The filter bag support cage was combined with vertical wires, supporting cages, top cap and bottom caps, as well as the venturi to the pressed purging air leading. For reducing the filter bags touch with the supporting rings of the bag supporting cage to make the filter bags broken, we developed the star shaped side view dust collector filter bag cage/ star ring filter bag cage; for increase the filter area, sometimes also design the filter bag with pleated design, so Zonel Filtech also developed the good quality pleated filter bag cages as requested.
Properties of filter bag cages from Zonel Filtech
1. Zonel filtech always design the filter bag cage according to the different filter bags used, also help to choose the suitable filter bags cages according to different working conditions, such as temperature, corrosive situation, dust with explosive or not, etc.
2. The material adopted the well treated steel wire, strong and with good elasticity, smooth surface.
3. The filter bag cage is strongly welded, won’t broken from the welding point for normal operation; the top side welding from the inner side, won’t touch with the filter bags and won’t break the filter bag.
4. The venturi with well designed, can lead pressed air to purging the filter bag efficiency but won’t hurt the filter bag.
5. The surface of the filter bag supporting cage can be treated with galvanized, organic silicon coated and so on as requested.
6. Various material is available, such as carton steel, SS304, SS316L, Titanium, etc.
7. The filter bag frame are available for all kinds of the filter bags, such as the round filter bag, oval shaped filter bags, pleated filter bags, etc.
8. The dust collector filter bag cage from zonel filtech can be designed with single pcs or multi-pieces combined style so as convenient to install.
