Glass fiber cloth bag is
suitable for various types of bag type dust collector
equipment with internal frame-type back-flushing (back-suction) wind or shrinking bag cleaning without frame in the center of the filter bag
. The filtering speed is usually below 0.5m / min. If the speed is too high, it is easy to blow out the filter bag or form a diafiltration. There are many dust spots in the cement industry. Compared with bulked yarn filters of the same thickness, the price is cheaper.
There are many mills in the cement industry. The temperature of the exhaust gas emitted by the dryer is low (close to zero temperature), the dust concentration is high, the water content is large, and the temperature of the exhaust gas is close to zero. The use of CWF-300-FCA filter media has a better effect. This filter media uses the outer lubricated twill fabric layout and is treated with hydrophobic treatment. Its abrasion resistance, folding resistance, and hydrophobicity have advanced a lot. After nearly ten years of application, the filter has good characteristics such as anti-condensation ability and long service life.
The most common cement production equipment of small and medium-sized cement plants is the vertical shaft kiln. The exhaust gas temperature of this kiln fluctuates greatly, and can dew when it is low, and exceeds the capacity of glass fiber when it is high. In recent years, the computer control has been used to deal with the fluctuating flue gas heading. The selection of CWF-3OOPSi filter media has played a good role in collecting dust from the vertical kiln exhaust of dozens of cement plants such as Shijing Cement Plant, Boshan Cement Plant, Zibo Cement Plant, and Tianjin Cement Plant. This filter material uses medium alkali glass fiber and post-treatment with PSi formula, which further advances the filter cloth's folding resistance, wear resistance and temperature resistance.
