“…Because of the low filtration velocity, the structure resistance can be ignored in this study. Accordingly, the pressure drop caused by filter media and dust cake is considered as the total pressure drop and can be calculated using Darcy’s law 31 – 34 . where is the total pressure drop of the filter (Pa), is the pressure drop caused by the filter media (Pa), is the pressure drop caused by the dust cake (Pa), is the permeability coefficient of the filter media (m 2 ), is the permeability coefficient of the dust cake (m 2 ), and is the effective filtration velocity (m/s).…”

In this study, a pressure drop model was developed through numerical simulation and experimentation for optimizing the design of the pleated structure of the filter media to extend the service life of the filter and reduce the ventilation energy consumption. The effect of the Stokes number on the dust deposition on the pleated filter media was revealed through numerical simulation. On this basis, a pressure drop model during dust loading was developed. The model suggests that under the same mass of dust deposition per unit area (W), the greater the pleat ratio (α), the greater the dust cake thickness and the effective filtration velocity in the effective filtration area. In addition, for V-shaped and U-shaped filters, the relative mean deviations between experimental and modeling total pressure drops are 3.68% and 4.82%, respectively. In other words, the proposed model accurately predicts pressure drop during dust loading. Furthermore, under the same α and $$W$$ W , the total pressure drop of the U-shaped filter is lower than that of the V-shaped filter, demonstrating the superior filtration performance of the U-shaped filter.

“…Given that the total pressure drop is fixed, the filtration velocity must decrease with the progression of the filtration process, resulting in a corresponding reduction in the pressure drop across each layer of the granular bed. However, the rate of dust accumulation is rapid in the upper filtering layer and is thus the dominant factor in that layer, causing an increase in the pressure drop across the layer with time [23]. The two aforementioned factors are balanced in the lower filtering layer, resulting in the essentially unchanged pressure drop from its initial level.…”

Effects of Temperature on the Filtration Characteristics of a Dual‐Layer Granular Bed Filter

The effects of temperature on the filtration efficiency and pressure drop of a duallayer granular bed filter were investigated in a hot dual-layer granular bed filter with experimental dust. Enhanced higher filtration efficiency was obtained with higher filtration temperature, and the removal efficiency of ultrafine dust was also at a high level. Simultaneously, the total pressure drop maintained at an acceptable range. The results demonstrate that the dual-layer granular bed has excellent prospects for application to low-temperature coal pyrolysis.

“…The first describes the resistance to air flow through the clean filter medium (pressure drop across the clean medium ∆p 0 ) while the second is the pressure drop across the dust cake deposited on the surface of the filter medium. It can be calculated from Equation (1) as the sum of pressure drop across the clean filter medium ∆p 0 and the pressure drop across the dust cake accumulated on the medium surface ∆p p [1][2][3][4][5][6][7][8]:…”

The specific beech wood dust resistance coefficient values were experimentally determined in the condition of pulse-jet filtration using a pilot-scale baghouse. The experiments were carried out for two variants of the filter medium. One of them had a PTFE (Polytetrafluoroethylene) membrane on the working surface. Three values of filtration velocity and seven levels of dust concentration at the filter inlet were used to determine the variability of the specific resistance coefficient of beech wood dust accumulated on the filter medium. The values of the specific beech wood dust resistance coefficient depend on filter medium finishing and filtration parameters: filtration velocity and dust concentration at the filter inlet. The high concentration of dust at the filter inlet and low filtration velocity should be used, especially in filters with surface finished media, for the reduction in pressure drop, which would affect in a significant reduction of energy consumption.
