The evolution path of bag filter: pulse technology leads efficient innovation
Aug 25,2025
The development of bag filters has always revolved around the iteration of "improving efficiency and reducing energy consumption", and the emergence of pulse bag filters has achieved a leap from "basic dust removal" to "high efficiency and energy saving", becoming the mainstream choice for global industrial dust control.
1、 Three generations of evolution of bag filter: from low efficiency to precision
1. First generation: Mechanical vibrating bag dust collector
Relying on mechanical devices to knock on filter bags for dust removal has an efficiency of only 85% -90%. The filter bags are prone to wear (with a lifespan of 3-6 months) and are only suitable for low concentration dust scenarios, gradually being phased out.
2. Second generation: anti blowing bag filter
By using reverse airflow to clean the ash, the efficiency is improved to 95%, but the cleaning cycle is long (1-2 hours/time), which is not suitable for high concentration and continuous production conditions (such as cement plants).
3. Third generation: Pulse bag filter
With "high-pressure pulse blowing" as the core innovation, compressed air is instantly blown into the filter bag, achieving a cleaning efficiency of 99.9% and achieving "millisecond level cleaning and non-stop operation", completely solving the pain points of the previous two generations.
2、 Pulse bag filter: evolved core advantages
1. Efficient dust removal: The removal rate of 0.1 μ m fine dust exceeds 99.9%, and the emission concentration is ≤ 5mg/m ³, which meets the ultra-low standards of EU CE and US EPA;
2. Energy saving and low consumption: The pulse blowing pressure is only 0.4-0.6MPa, which is 30% more energy-efficient than reverse blowing equipment, and the lifespan of the filter bag is extended to 2-3 years;
3. Foreign trade adaptation: Customizable 304/316L stainless steel material (corrosion-resistant) and high-temperature resistant filter material (260 ℃+), suitable for high-temperature factories in the Middle East and precision workshops in Europe and America, providing multilingual operation manuals.
The evolution of pulse bag dust collectors is not only a technological upgrade, but also a dual solution of "high efficiency and compliance+cost reduction and energy saving" for overseas factories, becoming the core category of foreign trade dust removal equipment.
