In reverse-air baghouses, the bags are fastened onto a cell plate
at the bottom of the baghouse and suspended from an adjustable
hanger frame at the top. Dirty gas flow normally enters the
baghouse and passes through the bag from the inside, and the dust
collects on the inside of the bags.
Reverse-air baghouses are compartmentalized to allow continuous
operation. Before a cleaning cycle begins, filtration is stopped in
the compartment to be cleaned. Bags are cleaned by injecting clean
air into the dust collector in a reverse direction, which
pressurizes the compartment. The pressure makes the bags collapse
partially, causing the dust cake to crack and fall into the hopper
below. At the end of the cleaning cycle, reverse airflow is
discontinued, and the compartment is returned to the main stream.
How to choose the filter bag ?
The filter bag plays a key role in the dust-cleaning process, so it
is very important to do the filter selection, which should be based
on its performance and the nature of the smoke, so as to have a
rational and optimized scheme.
The Factors that affecting the selection of the filter medium
The Select Indication of the Filter medium
A. Temperature
B. Chemical Property
C. Concentration of the dust content
D. Filter Gas Speed
