摘要：

The results of special field, pilot and bench scale studies have provided a rational basis for estimating woven fabric filter performance. Measurement of the amount and distribution of residual dust upon cleaned fabrics permits an accurate prediction of intermediate and final filtration parameters for cleaned and uncleaned regions of the fabric during subsequent filtration cycles. The predictive method is based upon the fact that dust dislodgement occurs at the dust/fabric interface in the form of flakes or slabs and not be surface spallation. The analytical concepts apply to filtration systems for fly ash, and also to any fabric/dust combination cleaned by mechanical shaking and/or bag collapse with reverse flow.
