Establishment of technical parameters for the dust-cleaning system of the air chamber type pulse-jet bag filter
气箱式脉冲喷吹袋式除尘器清灰系统主要技术参数的确定

In order to research the dust-cleaning mechanism of the air chamber type pulse-jet bag filter,energy equations of compressed gas flow were used to deduce a mathematical expression for the reverse air velocity. Based on the bench scale test results for the bag filter,the relationship between detachment stress and dust-cleaning efficiency was obtained. Adesign method for the dust-cleaning system is then suggested. Applying the ejecting flow theory,formulas for ejecting mass flow,nozzle diameter,compressed air pressure and compressed air quantity were also proposed. The reverse air velocity and flow could be calculated from the setting dust-cleaning efficiency under a certain dust load and the main technical parameters could then be determined.
