These are hung from a support. Their lower ends Slip over and are clamped onto cylindrical Sleeves that project upward from a plate at the bottom The dirty gas flows into the space below this plate and up inside the bags. The gas flows outward through the bags, leaving its solids behind. The clean gas then flows into the space outside the bags and is ducted to the exhaust stack or to some further processing

For the baghouse in Fig. 9.13 there must be some way of removing the cake of particles that accumulates on the filters. Normally this is not done during gas-cleaning operations, instead the baghouse is taken out of the gas stream for cleaning. When the gas flow has been switched off the bags are shaken by the support to loosen the collected cake

a weak flow of gas in the reverse direction may also be added to help diske Lodge the cake thus deflating the bags Often metal rings are sewn into filter bags at regular intervals so that the bag will onl partly collapse when the flow is reversed

ypically, for a major continuous source like a power plant, about five baghouses will be used in parallel, with four operating as gas cleaners during the time that the other one is being shaken and cleaned. Each baghouse might operate for two hours and then be cleaned for 10 minutes at all times one baghouse would be out of service for cleaning or waiting to be put back into service
