The base material of CWF 300 1 FQ filter material is the twill structure of medium alkali continuous glass fiber, with a thickness of 0.3 to 0.35mm, and retreated with reactive organosilicon and polytetrafluoroethylene suspension. This filter material is soft and smooth, easy to dedusting, can be used continuously at 250 degrees centigrade, and the price is cheap. In the kiln tail dust of Xuzhou cement plant, the filtration rate is about 0.5m/min, the filtration efficiency is 99.8%, and the upper intake negative pressure operation is adopted, and the chamber is used to shrink the dust. Under the above process conditions, the filter bag ran for 310 days without any breakage, and the cumulative damage rate was 28% for 2 years, of which 50% bags lived for more than 3 years.
The more common cement production equipment in China's small and medium cement plants is machine shaft kiln. The exhaust gas temperature of this kind of kiln fluctuates greatly, it can be exposed at low time, higher than glass fiber bearing capacity at high time, and the problem of dust collecting has not been well solved. In recent years, the problem of excessive gas temperature fluctuation has been solved by microcomputer control. The use of CWF 3OOPSi filter material has played a good role in the dust collection of shaft kiln tail gas in several dozens of cement plants, such as Shijing cement plant, Boshan cement plant, Zibo cement plant and Tianjin cement plant. This filter material is treated with alkali glass fiber and treated with PSi formula to further improve the bending resistance, abrasion resistance and temperature resistance of the filter cloth.
Some lessons learned from the use of filter bags
All kinds of filter materials have certain characteristics, and also have their shortcomings. Natural fibers (such as cotton, linen, silk, Mao Xianwei) and synthetic fibers (such as nylon, polypropylene, polyester, Nomex...) have good resistance to flexural and wear resistance, but their temperature resistance is poor, and the use of these filters must be strictly controlled. The use of over temperature makes the bag shrink quickly or even burn out, which will affect the service life.
