M.04Jet-Pulse Bag Filter Sizing

Determine the number of filter bags needed for a dust collection system.

Typically 0.8–2.0 m/min for jet-pulse filters, depending on the dust.

    This tool is for preliminary sizing. Final design must be verified with material tests, the relevant standards and equipment manufacturer data.

    Formulas

    Filter area
    A = Q [m³/min] / (A/C) [m/min]
    Bag area
    a = π · d · L (+ π·d²/4)
    Number of bags
    n = ⌈A / a⌉

    Choosing the air-to-cloth ratio

    The air-to-cloth ratio (filtration velocity) is the volume of air passing through 1 m² of filter fabric per minute. Lower values are used for fine, sticky or high-concentration dust, higher values for coarse, dry dust. The final value should be set from dust analysis and filter manufacturer data.

    We prepared jet-pulse filter manufacturing drawings for the dust collection systems of our Bigadiç granular fertilizer and Kırka borax pentahydrate plants.
