The vertical bag filter, also known as the dry filter dust collector, is a type of dry high-efficiency dust collector. It employs bag-type filter components made of fiber-woven materials to capture solid particles in dusty gas. The operational principle involves dust particles passing around the filter cloth fibers, where they collide with the fibers due to inertial force and are subsequently intercepted. Fine dust particles (with a particle size of 1 μm or less) continuously change their direction of movement due to the impact of gas molecules (Brownian motion). Since the gaps between the fibers are smaller than the free path of the Brownian motion of gas molecules, the dust particles collide with the fibers, come into contact with them, and are separated. Proses kerja sistem dipengaruhi oleh faktor -faktor seperti metode tenun bahan filter, kepadatan serat, difusi, inersia, oklusi, gravitasi, efek elektrostatik, dan metode pembersihan debu .
The filter cloth material is critical to the performance of the bag filter. A well-performing filter cloth not only possesses specific density and air permeability but also exhibits excellent corrosion resistance, heat resistance, and high mechanical strength. Currently, the heat resistance of fibers can reach up to 250–350℃.

Under the guidance of the device, large-particle dust is separated and directly falls into the ash hopper. The remaining dust is evenly distributed across the filtration areas of each chamber along with the airflow. After filtration, the clean gas is discharged through the filter bags, upper box body, lift valve, and exhaust pipe.
