The dust removal efficiency of the film-coated room temperature dust removal bag directly affects the working performance of the bag filter. When using and selecting the film room temperature dust filter bag, pay attention to the maintenance of the film room temperature dust removal bag, which not only affects the service life of the bag filter, but also it also has a great influence on the dust removal effect of the coated room temperature dust removal bag:
Based on the experience summary of making bag filter and film-coated room temperature dust-removing bag, the dust removal efficiency of film-coated room temperature dust-removing bag can be improved from different aspects:
The dust-removing bag is sealed with polyester needle felt dust removal system. The dust removal system mainly includes the bag dust collector body and other equipment of the dust collection system, such as star discharge, import and export valves, conveying equipment and pipelines, and inspection doors. Strengthen the sealing of each inspection hole and door, the inspection door adopts double doors, and the sealing around the door adopts heat-resistant silicon rubber. The sealing of transportation equipment should also be maintained to reduce and solve air leakage.
Secondly, all the connections of the shell must be welded continuously, and there must be no leaks or openings (the door holes and the cleaning and blanking parts 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 duct, shell, upper flower plate and other parts, and repair the worn parts in time.
The second is the reduction of dust management and soot concentration. There are technical requirements for the inlet concentration, temperature and wind speed of the dust collector when the design is matched. During the transformation of the production system, it may be necessary to increase the wind speed and increase the lifting amount. In this case, considering the capacity and possible results of the dust collector, it is necessary to match each other as much as possible.
Reduce the damage of the film-coated room temperature dust removal cloth bag, and keep the middle line of the nozzle consistent with the middle line of the filter bag during bagging and spot inspection. Otherwise, the easy-cleaning gray iron needle felt is damaged at the outlet of the filtration bag.
