Superfine PPS (polyphenylene sulfide) staple fiber and PTFE (polytetrafluoroethylene) fiber are selected for blending on the dust facing surface, which will not shrink under high temperature, will not affect the gap between the filter bag and the bag cage and ensure the dust filtration performance.
The filter material coated with the high temperature permeable membrane has small pore size and high porosity which can improve the filtration accuracy of the filter material. The primary dust layer is relatively thin, which is easier to remove dust, and the dust stripping rate is high.
PTFE (polytetrafluoroethylene) will form a dense protective film on the fiber surface, which improves the oxidation resistance and corrosion resistance of the filter material. Besides it also has good water and oil repellency and anti-condensation function.
The upper and lower pieces of the stitches on the filter bag are flat and free of folds. The bag mouth and the interface at the bottom of the bag are folded evenly so there will be no gap after being installed on the tubeplate.
Transporting the whole carton of filter bags
into the air purification chamber through the manhole door. The filter bag must
be transported in the whole carton otherwise the filter bag is easy to be
scratched. | The whole carton of filter bags shall be stacked
neatly in the air purification chamber. |
Distributing filter bag installation protective
sleeves to filter bag installation workers. | Putting the filter bag protection sleeves into
the tubeplate holes. |
Inserting all the filter bags into the tubeplate
holes and taking out the protective sleeves. | Bending the elastic ring of the filter bag with
both hands. The groove of the outer bag mouth is aligned with the edge of the tubeplate
hole. The bag ring is tightly attached to the tubeplate in the whole circle
and evenly tensioned. |
Usually, a "snap" sound can be heard,
which means that the opening of the filter bag has been clamped with the tubeplate
hole. If it is not clamped, press it by hand or gently tap the periphery with a
rubber hammer until it is tensioned. | Please notice to install backward from the
tail end of the jet pipe to the manhole door, which can avoid workers from
stepping on the elastic circlip of the filter bag. |
