如何判斷除塵布袋是否需要更換？
How to Tell When Dust Collector Filter Bags Need Replacement

在陶瓷、石材、玻璃與建材行業中，脈衝除塵器是控制粉塵排放的重要設備，而濾袋（Filter Bags）則是其核心元件。
In industries such as ceramics, stone, glass, and building materials, pulse jet dust collectors are essential for dust control, with filter bags as their core components.

濾袋的使用壽命有限，如果未能及時更換，不僅會降低除塵效率，還可能導致環保超標，甚至損壞風機與管道。
Filter bags have a limited service life, and failing to replace them on time not only reduces efficiency but may also lead to regulatory violations or even damage to fans and ducts.

判斷濾袋需要更換的主要信號
Key Signs That Filter Bags Need Replacement

• • 壓差持續升高：當進出口壓差長期高於正常值，表示濾袋堵塞。
    Increasing Differential Pressure: A consistently high pressure drop across the bags indicates clogging.
  • 除塵效率下降：如果排放口粉塵明顯增加，代表濾袋破損或老化。
    Reduced Dust Collection Efficiency: Visible dust emissions at the outlet mean bags are torn or aged.
  • 運行能耗上升：風機功率消耗異常升高，可能因濾袋堵塞導致氣流不暢。
    Rising Energy Consumption: Higher fan power consumption may result from clogged bags restricting airflow.

• 物理損壞跡象：檢查濾袋是否有破洞、磨損或硬化。
  Physical Damage: Check bags for holes, abrasion, or stiffening.
• 使用時間過長：大部分濾袋壽命為 1–3 年，超期使用風險大。
  Exceeding Service Life: Most bags last 1–3 years; beyond this, failure risk increases.

不同材質濾袋的壽命差異

濾袋材質會影響耐熱性、耐磨性與整體壽命。

定期檢測的重要性
The Importance of Regular Inspections

工廠應建立濾袋檢測與更換制度，包括：
Factories should establish inspection and replacement schedules, including:

1. 每月記錄進出口壓差，判斷是否堵塞。
   Record differential pressure monthly to identify clogging.
2. 定期觀察排放口是否有可見粉塵。
   Regularly check for visible dust at outlets.
3. 年度停機檢查濾袋物理狀況。
   Inspect bags physically during annual shutdowns.
