Explosion Proof Cartridge Dust Filter for Cement Silo

Introduction
Cartridge filters are advanced filtration systems that use cylindrical filter cartridges as the main filtering elements. Based on the principles of pulse bag filters, they represent an innovative solution for air dust and industrial powder (smoke) removal. These filters offer high air volume, low operating pressure (0.2–0.6 MPa), and a low resistance loss (800–1000 Pa), making them highly efficient and user-friendly. With their compact design, excellent emission standards, smaller footprint, and cost-effective operation, cartridge filters have become a preferred choice in many industries.

Working Principle of Cartridge Filters
A typical cartridge filter consists of a cabinet, filter cartridges, and a cleaning system. When dusty air enters the collector, the sudden expansion and air distribution plate cause larger particles to settle in the ash hopper due to gravity and inertia. The finer particles then enter the filtration chamber, where they are captured by the filter material through mechanisms such as Brownian diffusion and sieve filtration. As dust accumulates on the surface of the filter, the resistance increases. Once the resistance reaches a set value, the system initiates a cleaning cycle. Compressed air is injected into the filter cartridges, causing them to expand and vibrate, which dislodges the accumulated dust. The dust then falls into the ash hopper and is discharged through the discharge valve.

Applications
Cartridge filters are widely used in various industrial applications, including blast furnace blower inlets, oxygen generators, air compressor inlets, control room gas cleaning, clean workshops, public building HVAC systems, and low-concentration flue gas treatment. With continuous advancements in materials and dust removal technology, their application scope has expanded significantly. Today, they are commonly found in construction materials, metallurgy, power generation, food processing, and chemical industries, often replacing traditional bag filters and electrostatic precipitators.

Structure and Components
The cartridge filter is composed of three main parts: the filter cartridges, the housing, and the ash removal mechanism.

(1) Filter Cartridges: Each cartridge consists of an outer layer, inner layer, and a middle foldable filter material. The outer and inner layers are covered with metal mesh or hard plastic nets, while the middle layer is designed to maximize filtration area through folding. A sub-micron ultra-thin fiber layer is added to enhance filtration efficiency, with fiber spacing ranging from 0.12 to 0.6 µm. This structure ensures high efficiency and large surface area for effective dust capture.

(2) Housing: The housing includes the gas tank and ash hopper. The gas tank provides space for cleaning operations, ensuring even airflow distribution, while the ash hopper collects the dust after it is removed from the filter cartridges.

(3) Ash Removal Mechanism: This includes components such as the blowpipe, pulse valve, and air bags. When the dust buildup on the filter cartridges reaches a certain level, the system triggers a cleaning cycle. Compressed air is injected into the cartridges, causing them to expand and vibrate, thus dislodging the dust. The dust is then collected in the ash hopper and discharged through the discharge valve.
