Waiting online, urgently! ! Problems with damaged cloth bags
Thread Content
During the retrofit of the ultra-low emission project, the impeller of the exhaust fan was replaced due to an increase in the overall system resistance. To prevent the bag filter from being flattened, cross supports have been added inside the bags. During subsequent operation, it was found that the filter bags frequently collided with the supports, resulting in localized wear and damage to the bags. I would like to ask the professionals: Have you encountered this situation before? Is there any good solution? Waiting online urgently. Thank you! ! !
Add a bag cage? Why add a cross?
Renovation project: The baskets can no longer be added；
Replacing the filter bag not only increases costs, but it’s also not very suitable to do it while the system is in operation. It was replaced last time, and the interval between replacements was too short – it broke again in less than 2 weeks
I roughly understand what you mean. The main issue is that your cloth bag isn’t fixed; it contracts when the pressure is low and expands when the pressure is high. It’s necessary to design a fixed double-layer cage framework to hold the cloth inside, so as to ensure that the bag doesn’t deform significantly.
If you’re not afraid of the hassle, just sew it~~
It will still wear out after being sewn?
This plan seems okay. Are there any real-world examples? ?
No, but I can help you design it; it’s very simple
A layer of wear-resistant filter cloth can be added in areas where collisions may occur; it doesn’t cost much, and improvements can be made at an appropriate time.
