Burst filter bag monitoring

Burst filter bag monitoring

Burst filter bag monitoring

(OP)
We have a number of bag filters around our site that can sometimes burst giving emmissions out to the environment. I wondering if anyone knows of a reletivley low cost solution to detecting a burst quickly. The products used are mostly cornflour and maize dust. We have tried detecting the drop in differential pressure but there doesnt seem to be any change in pressure when a bag bursts due to the size of tear being quite small.
Thanks for any replies in advance.
Colin.

RE: Burst filter bag monitoring

Have you talked to the local rep for the filter??

Not knowing any info about your filter, the local rep should be able to contact the factory and define/suggest a different material for the bag.  Are you currently using nylon that can tear easily??

Opacity monitors don't work for you?

RE: Burst filter bag monitoring

I'll agree with Mr. Halloran.  Either an Opacity monitor, or particle counter to capture a spike in debris downstream.  Typically though, I've only come across this problem when I've tried the cheaper generic retrofit filters instead of the OEM elements.  This could be the root cause.  Why monitor the defect when you can kill the cause?  Best of luck.

I understood that the units were typically equipped with methods of measuring the "clean" air discharge.

Alternatively the "dP" of the unit may be of use for monitoring.
