When using a dust collector, the dust removal efficiency of the dust bag is an important factor affecting the working performance of the dust collector, and it also affects people's choice of dust collector. Therefore, the dust removal efficiency of the dust bag should be improved from different aspects.
First, the dust-removing cloth bag should be strengthened and sealed. The dust removal system mainly includes the main body of the bag dust collector and other equipment of the dust collection system, such as star discharger, inlet and outlet valves, conveying equipment and pipelines, inspection doors, etc. Strengthen the sealing of each inspection hole and door. The inspection door is easy to use double-layer doors. The seal around the door should be heat-resistant silicone rubber. The sealing of conveying equipment should also be strengthened to maintain and reduce air leakage. All the joints of the shell must be continuously welded, and there must be no leaks or holes (the door holes and the ash cleaning material are easy to leak). Therefore, it is necessary to strengthen the inspection and spot inspection of the dust collection system, check the integrity and tightness of the dust collector air pipe, casing, upper flower plate and other parts, and find that the wear-through parts must be repaired in time.
The second is to strengthen dust management and reduce the dust concentration of flue gas. There are certain technical requirements for the inlet concentration, temperature, and wind speed of the dust collector when designing the supporting equipment. When the production system is transformed, it may be necessary to increase the wind speed and increase the amount of dust. At this time, it is necessary to consider the capacity of the dust collector and the possible consequences, and try to match each other.
After that is to reduce the damage of dust bag. The air outlet end of the dust removal filter bag is easy to be damaged. When installing and repairing the bag, be sure to keep the center line of the blowout port and the center line of the filter bag coincide. Otherwise, the air outlet of the filter bag will be damaged.
