“…Their numerical study also reported the effect of cylinder shape on dust cleaning performance of pulsed-jet pleated filter cartridges. Li et al [23] and other researchers found that the greater the peak pressure inside the filter cartridge, the less the residual dust attached to the surface of the filter cartridge. Pulsed-jet cleaning airflow would cause the filter bag to shake and deform violently, which would produce great stress, and the flow field in the filter bag would change very quickly.…”

“…The cleaning resistance caused by the filtering speed does not affect the cleaning efficiency under pressure, but the higher the filtering speed becomes, the greater the cleaning resistance when peak pressure is insufficient. This is caused by the amount of residual dust increasing, and the cleaning efficiency is not good [32]. In addition, the type of filter dust will also significantly affect the cleaning efficiency of the dust collection system [3].…”

A growing number of manufacturers are realizing cost and environmental benefits through the sustainability of innovation and optimization processes. Based on polluting less and creating less, the study is pursuing sustainability on increasing operational efficiency by reducing costs and waste. Pulse dust collection systems are commonly used filtration equipment in industries and have lots of energy consumption due to running all day. This study is focused on the optimal parameters for energy saving and cost reduction, and the model is represented by the pressure drop of the filter and the residual powder. The characteristic values of the cleaning efficiency and the air permeability reduction are used for MATLAB to analyze the optimization state. This study found that the material of filter elements, the type of dust, the conditions of pulse-jet, and the filtering speed are the factors that affect the operational efficiency. In terms of cost, the pulse interval time in 10 s is the best parameter, and the pulse time does not affect the overall cost of the filter. Considering energy saving, 0.1 s of the pulse time is the best parameter. In addition, a lower dust concentration is a way to improve efficiency for increasing the filter life and reducing cost.

“…There have been numerous studies attempting to understand the mechanism of filter bag cleaning and optimize the parameters of a bag cleaning system to enhance the cleaning performance [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Qian et al investigated the optimal relationship of nozzle diameter with jet distance and blow tube size, while Shim et al and Andersen et al developed novel configurations of pulse-jet nozzles and examined them through experimental and computational methods [7][8][9][10].…”

In this study, the effects of various parameters of the filter bag cleaning system, such as the blow tube size (20A, 40A, 50A), the nozzle diameter (5, 10, 15, 20, 25, 30 mm), the initial tank pressure (0.3, 0.4, 0.5, 0.6, 0.7 MPa), and the pulse duration (50, 100, 150, 200, 250, 300 ms), were evaluated with a view of peak pressure and pressure impulse. This study shows that the peak pressure and pressure impulse are not always in a proportional relationship, since pressure impulse aggregates static pressure and pressure over elapsed time together. For the system investigated, it is found that increasing the blow tube size and pulse duration induce a larger pressure impulse with little change in peak pressure, while higher initial tank pressure enhances both peak pressure and pressure impulse. On the other hand, a larger nozzle diameter was found to increase peak pressure rather than pressure impulse throughout the bag. The experimental results suggest that a higher initial tank pressure is a convenient way to elevate the overall dust-cleaning performance of pulse-jet systems, while other parameters (blow tube size, nozzle diameter, initial tank pressure) can be adopted according to the desired effect for given environment.
