The latitude and longitude strength of the woven filter material has not been damaged by acupuncture, which is several times higher than that of the ordinary felt filter material. Because of its high strength, it can be processed into a filter bag of 10 meters or even 12 meters long; the filter bag is under high temperature. It will not shrink, almost keep the original size, will not affect the gap between the filter bag and the skeleton, and ensure the cleaning effect. The elongation of the glass fiber filter bag is less than 8%. During the filtration operation, the weight of the filter material plus the weight of the dust layer will not cause the filter bag to elongate, and the cyclical damage caused by the air pressure cleaning to the filter bag is also greatly reduced. . When the woven filter material is cleaned, the filter material is serpentine and the dust is easy to be peeled off; the dusting pressure is small, the number of cleaning times is small, the consumption of compressed air is effectively reduced, and the running cost is saved. As long as it has an ideal airflow distribution and a properly designed cleaning system, the pressure difference of the woven filter material during operation is very stable, and the system resistance rises very slowly after long-term operation.
