Bag dust collectors are divided into five categories. The cleaning method is the main criterion for classifying bag dust collectors.
(1) Mechanical Vibration
Baghouse dust collectors that use mechanical devices (including manual, electromagnetic, or pneumatic devices) to vibrate filter bags for cleaning, featuring two types of construction: a non-compartmentalized design suitable for intermittent operation and a compartmentalized design suitable for continuous operation.
(2) Individual Room Back-Blow Type
A pulse-jet bag filter with a divided-chamber structure, utilizing valves to sequentially switch the airflow through each chamber, causing the filter bags to collapse or inflate under reverse airflow for dust removal.
(3) Nozzle Backflush
Bag dust collector with reverse airflow provided by a high-pressure blower or compressor, utilizing moving nozzles for reverse cleaning, causing the filter bags to deform, vibrate, and penetrate the filter material to remove dust (all non-divisional structure).
(4) Vibration and Reverse Blowing Combined
Baghouse dust collector using both mechanical vibration (including electromagnetic or pneumatic vibration) and reverse air cleaning methods (all in separate compartment design).
(5) Pulsed Jet Type
A bag dust collector powered by compressed air, utilizing the instantaneous release of compressed air from a pulse jetting mechanism to induce several times the amount of secondary air to be高速 injected into the filter bag, causing it to急剧 inflate. It relies on impact vibration and reverse airflow for cleaning the dust.
