Working Principle of Anti-static Dust Filter Bags
In order to effectively solve the problem of static electricity, anti-static dust filter bags adopt special designs and materials. Their main working principle is to form a conductive network by mixing conductive fibers, such as stainless steel fibers, carbon fibers, or conductive polymer fibers, into the filter material. When static electricity is generated during the dust filtration process of the filter bag, these conductive fibers can quickly conduct away the static charge, preventing the static electricity from accumulating on the surface of the filter bag. At the same time, some anti-static dust filter bags also undergo anti-static treatment on the surface of the filter material, such as using anti-static coatings, to further reduce the surface resistance of the filter bag and enhance its static conductivity. This two-pronged approach enables anti-static dust filter bags to continuously and stably play an anti-static role in complex industrial environments, providing a strong guarantee for the safe operation of dust removal systems.Wide Range of Application IndustriesAnti-static dust filter bags are widely used in many industries.- Chemical Industry: The chemical production process involves a large number of flammable and explosive chemicals and dust, such as organic dust generated in organic synthesis workshops and light oil mist in petrochemical plants. Once these substances encounter electric sparks, they are extremely likely to cause explosions and fires. Anti-static dust filter bags can effectively filter dust and eliminate static electricity hazards in all aspects of chemical production, such as tail gas treatment of reaction kettles and workshop ventilation and dust removal, ensuring the safe and stable operation of chemical production.
- Coal Industry: A large amount of coal dust is generated during coal mining, processing, and transportation.

Anti-static Dust Filter Bags: A Safety Barrier for Industrial Dust Removal
During the industrial production process, dust pollution is a problem that cannot be ignored. It not only causes serious damage to the environment but may also endanger the health of workers. More seriously, in some specific industries, such as chemical engineering, coal mining, and metal processing, if dust mixes with air to a certain concentration and encounters a fire source or electrostatic discharge, it is extremely likely to trigger an explosion accident, causing irreparable losses. Therefore, efficient dust removal equipment and technologies are crucial for industrial safety production. As a key dust removal component, anti-static dust filter bags play an irreplaceable role in preventing dust explosions and ensuring production safety.
Hazards Caused by Static ElectricityIn industrial dust removal systems, factors such as the friction between dust and filter bags and the high-speed flow of air can easily generate static electricity in the filter bags. For ordinary filter bags, once static electricity is generated, it is difficult to dissipate in a timely manner and will gradually accumulate on the surface of the filter bags. When the static electricity accumulates to a certain extent, electrostatic discharge may occur, generating electric sparks. In an environment with flammable and explosive dust, these electric sparks are like a bomb that may explode at any time, highly likely to trigger a dust explosion, bringing huge casualties and property losses to enterprises. For example, in flour mills, flour dust particles are small and flammable, and a large amount of dust is generated during the production process, such as in the grinding and conveying processes. If the filter bags in the dust removal system do not have anti-static functions, dust explosion accidents caused by static electricity may occur at any time. According to relevant statistical data, in some past dust explosion accident cases, the proportion of accidents caused by static electricity is quite high, which fully highlights the importance of anti-static dust filter bags in industrial production.Working Principle of Anti-static Dust Filter BagsIn order to effectively solve the problem of static electricity, anti-static dust filter bags adopt special designs and materials. Their main working principle is to form a conductive network by mixing conductive fibers, such as stainless steel fibers, carbon fibers, or conductive polymer fibers, into the filter material. When static electricity is generated during the dust filtration process of the filter bag, these conductive fibers can quickly conduct away the static charge, preventing the static electricity from accumulating on the surface of the filter bag. At the same time, some anti-static dust filter bags also undergo anti-static treatment on the surface of the filter material, such as using anti-static coatings, to further reduce the surface resistance of the filter bag and enhance its static conductivity. This two-pronged approach enables anti-static dust filter bags to continuously and stably play an anti-static role in complex industrial environments, providing a strong guarantee for the safe operation of dust removal systems. -

The wide range of applications for the DMF – ZM – 40 pulse valve
The DMF – ZM – 40 pulse valve, with its outstanding performance, has extensive and crucial applications in numerous industrial fields, becoming an important component for ensuring the production environment and equipment operation.
In the field of dust removal, especially in the pulse bag-type dust collector system, the DMF – ZM – 40 pulse valve is regarded as the core component. As the “switch” of the dust cleaning blow-off system’s compressed air, it is precisely controlled by the pulse blow-off controller’s output signal, and it performs dust cleaning by blowing on the filter bags row by row (section by section). In boiler dust collectors, it can promptly remove a large amount of dust generated during boiler operation, preventing dust accumulation from affecting the thermal exchange efficiency and safe operation of the boiler; in medium-frequency electric furnace dust collectors, in the presence of high-temperature and high-concentration dust environment, the DMF – ZM – 40 pulse valve can still work stably, ensuring the air quality in the electric furnace workshop and protecting the health of workers. Moreover, in various dust removal equipment such as casting-specific dust collectors, woodworking-specific dust collectors, and mining-specific dust collectors, its busy “presence” can be seen, creating a clean environment for industrial production.
In environmental protection waste gas treatment, the DMF – ZM – 40 pulse valve also plays an important role. For example, in plasma waste gas purification equipment and spray towers, it participates in the waste gas treatment process. By controlling the blow-off of compressed air, it assists the purification equipment in capturing and separating pollutants in the waste gas, improving the waste gas purification efficiency, and helping enterprises meet environmental protection emission standards and reducing pollution to the atmospheric environment.In some industrial production processes that require precise control of gas flow and pressure, the DMF – ZM – 40 pulse valve also performs well.

In-depth Analysis of the Working Principle of DMF – ZM – 40 Pulse Valve
In industrial dust removal systems, the DMF – ZM – 40 pulse valve plays a crucial role, and its efficient and stable operation relies on a unique and ingenious working principle.
From a structural perspective, the DMF – ZM – 40 pulse valve is mainly divided into two gas chambers by a diaphragm. When the entire system is connected to compressed air, the compressed air will slowly enter the rear gas chamber through the throttle hole. At this time, the pressure in the rear gas chamber gradually increases until it tightly presses the diaphragm assembly against the output port of the valve, thus putting the electromagnetic pulse valve in the initial “closed” state, like a meticulous guard, firmly controlling the flow of compressed air.
When the pulse blowing control instrument sends an electrical signal, this signal is like giving the pulse valve an “open” instruction. The electrical signal causes the armature of the electromagnetic pulse valve to move rapidly backward, thereby opening the exhaust hole of the rear gas chamber. The air in the rear gas chamber is rapidly expelled in a short period of time, and the pressure instantly drops. Under the action of the pressure difference, the diaphragm assembly moves backward, and the compressed air that was previously blocked rushes out through the valve output port at high speed. At this time, the electromagnetic pulse valve enters the “open” state, and the powerful blowing airflow cleanses the filter bag, blowing off the dust adhering to the surface of the filter bag, ensuring the efficient operation of the dust removal system.
When the electrical signal from the pulse blowing control instrument disappears, the armature of the electromagnetic pulse valve returns to its initial position under the action of the reset device, and the exhaust hole of the rear gas chamber closes. The rear gas chamber then begins to intake air through the throttle hole, and the pressure gradually rises. The diaphragm assembly re-contacts the output port of the valve again, and the electromagnetic pulse valve returns to the “closed” state, waiting for the next blowing command to arrive. This precise and efficient working mode enables the DMF – ZM – 40 pulse valve to operate stably in the dust removal and blowing system of the pulse bag dust collector, continuously contributing to the purification of industrial production environments.

Manufacturing Process of PPS Dust Filter Bags
Fiber Selection and Pretreatment
The production of PPS dust filter bags begins with the selection of high-quality PPS fibers. These fibers usually need to be pretreated before use to remove impurities and adjust the surface properties of the fibers, ensuring better bonding during subsequent processing and improving the overall performance of the filter bags. Pretreatment methods include washing, drying, surface modification, etc.Needle FeltingThe pretreated PPS fibers are carded into a web and then needled by a needling machine. During the needling process, barbed needles repeatedly penetrate the fiber web, causing the fibers to entangle with each other, forming a needle felt with a certain thickness and strength. The needling process enables the fibers to interweave in three-dimensional space, increasing the dirt-holding capacity of the filter bags and improving the filtration accuracy. By controlling the needling density and depth, the structure and performance of the needle felt can be adjusted to meet the requirements of different working conditions.Surface TreatmentTo further enhance the performance of PPS dust filter bags, the needle felt is usually subjected to surface treatment. Common surface treatment methods include singeing, calendering, and film coating. Singeing treatment can remove the fluff on the surface of the filter bags, reducing dust adhesion and making dust removal easier. Calendering treatment rolls the surface of the filter bags under high temperature and pressure, making the surface smoother and improving dust release. Film coating involves covering the surface of the filter bags with a Polytetrafluoroethylene (PTFE) film. This film has a microporous structure, which can further improve the filtration accuracy, achieving efficient filtration of ultra-fine dust particles. Meanwhile, it can also enhance the water and oil resistance of the filter bags. -
PPS Material Dust Filter Bags: Reliable Guardians of Industrial Environmental Protection
Dust pollution is a non-negligible issue in industrial production. It not only severely damages the environment but also endangers the health of workers and affects the normal operation of production equipment.
