Application of needled felt filter bag products


Suitable for filtering general industrial liquids such as electroplating E, D paint, ink, paint, food, chemical, grain and oil and other chemical liquids.


Next, let's talk about the phenomenon that the filter bag will be moistened by the filter bag.


Normally, bilge circle will pulse bag dust filter bag pressure within the plate hole, through the plate will be in the box pulse bag filter dust chamber with the case on strict distinction between the net, if the ring and flowers have cracks on plate hole, no seal, will cause the dust gas directly into the net of pulse bag filter air indoors, so the vent outlet will start to take a grey.


At this time, it is necessary to check the installation of the pulse bag filter bag one by one, the gap should be pressed, damaged should be repaired or replaced in a timely manner. The damage of filter bag will lead to the direct discharge of dusty gas, and smoke will be emitted from the exhaust cylinder. It is suggested that the filter bag of pulse bag filter should be replaced after the damage of the filter bag of pulse bag filter is determined. It is suggested that the filter bag of pulse bag filter on the same stage should be replaced at the same time to ensure their common resistance.


When the pulsed bag filter deals with those high temperature and high humidity gases, once the temperature of the gas is lower than the dew point temperature, the water vapor will condense and dew will occur, and then the filter bag will be damp. A large amount of dust is adhered to the surface of the filter bag, which clogs the pores and leads to the inability to clear the compressed air sprayed by the pulsed bag dust collector, resulting in the phenomenon of bag paste. The pulsed bag filter will lose the function of dust cleaning, the resistance will become larger, and the running state will gradually deteriorate. In order to prevent pulsed bag filter from forming dew bag, it is necessary to keep the temperature of treating gas higher than 25℃-35℃ or so.
