Estimating Baghouse Loading
Estimating Baghouse Loading
(OP)
I have been reviewing some old documentation for environmental permitting at the facility I work. We use filter baghouses with forced draft to collect dust from unloading processes. The material is unloaded to the baghouse then is gravity fed from the baghouse through a rotary valve to the tankage below. The estimate for the particulate emissions uses a "98% of the material drops out due to velocity change and is not part of the baghouse loading". Has anyone ever heard of this? It seems likely that the filters will not have filter the entire loading as the solids will drop below, but I am unfamiliar with this usage, especially considering Potential to Emit Calculations.
Any thoughts?>

Or is the baghouse a pollution control device to prevent the dust from contaminating the indoors or outdoors environment?

My new application would be for dust collection only. But I am trying to understand all cases.
The permitting for bag houses has been assumed as an ambiguous %, but I believe, since we are only regulated on PM10, that it should only be applicable to particles 10 microns or less.
You have got me really thinking now....

If indoors does it need to be vented outside?
Is the dust hazardous?
Is it visible from outside the baghouse?
