Bag filter: the "green guardian" in the industrial environmental protection process
Aug 01,2025
In today's world where the concept of green development is deeply rooted in people's hearts, bag filters, as the "environmental guardians" of industrial waste gas treatment, are demonstrating their abilities in various industrial fields with their efficient and stable dust removal performance. This dust removal equipment, which uses fiber fabric filter bags to capture dust, can capture inhalable particles larger than 0.1 microns through a composite mechanism of interception, inertial collision, and diffusion. The dust removal efficiency can generally reach over 99.5%.
In the steel and metallurgical industry, bag filter equipment builds a three-dimensional protective net in areas with excessive dust concentration, such as the tail of sintering machines and blast furnace ore tanks. The rotary kiln tail and raw material grinding system in the cement industry achieve stable dust removal under high temperature and high humidity conditions through the application of ultra long bag dust collectors, helping enterprises achieve ultra-low emission standards.
The process exhaust treatment of chemical enterprises reflects the flexibility of dust collector equipment. The innovative application of anti-static membrane filter material has successfully solved the dust removal problem in explosive conditions such as PTA plants. According to statistics, the installation rate of bag filter equipment in the power industry has reached 78% in 2023, an increase of 32 percentage points from ten years ago, becoming a standard configuration for coal-fired power units.
With the deepening of the Air Pollution Prevention and Control Law, technological innovations such as intelligent dust cleaning systems and high-temperature resistant nano filter materials continue to optimize the performance of dust removal equipment. As the backbone of industrial waste gas treatment, bag filters are writing a new chapter in the high-quality development of environmental protection equipment, injecting green energy into the construction of a beautiful China.
