Pulse Dust Collector
Bag-type dust collector, also known as bag filter or filtering dust collector, is a dry-type dust removal equipment that uses organic or inorganic fiber filter cloth to filter the dusty gas and achieve the separation of dust from the gas.
Bag-type dust collectors are highly efficient dust removal devices that utilize filter bags as the core filtering elements to purify the dusty gas. The core principle is that when the dusty gas enters the dust collector, the dust particles in the gas flow will be intercepted by the fiber layer of the filter bag – larger particles are directly adhered to the surface of the filter bag due to inertial collision, while smaller particles are captured through diffusion, electrostatic adsorption, etc. The purified gas can then pass through the gap between the filter bag fibers and be discharged, thereby achieving gas-solid separation. This equipment is mainly composed of the filtration system (filter bags, filter bag frame, baffle), the cleaning system (pulsing valve, blow-off pipe, air tank), the ash hopper and ash discharge system (ash hopper, ash discharge device), the inlet and outlet gas system, the control system, and the supporting structure.

Application of Bag-type Dust Collector
1. Industrial Production Fields
(1) Steel and Metallurgical Industry: In processes such as blast furnace ironmaking, converter steelmaking, and electric furnace steelmaking, a large amount of dust containing iron oxide and coke dust will be generated. Bag-type dust collectors can efficiently capture these dust particles, making the emitted gas meet environmental protection standards. At the same time, valuable metal dust can be recovered for resource recycling.
Benefits: Meeting emission standards, resource recycling.
(2) Cement and Building Materials Industry: In the processes of crushing, grinding, calcination, and packaging in cement production, a large amount of dust will be generated. Bag-type dust collectors can effectively control dust emissions, ensuring the working environment in the workshop, improving product quality, and reducing pollution to the surrounding environment.
Benefits: Reducing environmental pollution, improving product quality.
(3) Chemical Industry: In chemical production, various chemical reactions will produce dust and exhaust gas with different chemical components, such as sulfur dioxide dust in sulfuric acid production and ammonia dust in fertilizer production. Bag-type dust collectors can select appropriate filter materials based on the characteristics of the dust to efficiently filter the dust and also adsorb and purify some harmful gases.
Benefits: Efficient filtration, purifying some harmful gases.
(4) Mechanical Processing Industry: In processes such as cutting, grinding, and welding in mechanical processing, metal chips, grinding debris, and welding smoke will be generated. Bag-type dust collectors can promptly capture these dust particles to prevent them from spreading in the workshop.
Benefits: Protecting workers’ health, also helping to improve processing accuracy and product quality.
(5) Food Processing Industry: In processes such as grain processing, flour production, and feed processing, a large amount of grain dust will be generated. Bag-type dust collectors can use food-grade filter materials to effectively collect the dust while avoiding contamination of food, ensuring food hygiene and safety.
Benefits: Avoiding food contamination, ensuring food safety and hygiene.
2. Environmental Protection Field
(1) Garbage Incineration Treatment: Garbage incineration will produce smoke containing dust, dioxins, heavy metals, etc. Bag-type dust collectors, in combination with other purification equipment, can effectively remove dust and some harmful gases from the smoke, reducing environmental pollution and being an important component of the smoke purification system in garbage incineration power plants.
Benefits: Reducing environmental pollution.
(2) Industrial Exhaust Gas Treatment: For industrial enterprises that emit dust and harmful gases, bag-type dust collectors can be used as the front-end dust removal equipment to first efficiently capture the dust, providing favorable conditions for subsequent exhaust gas purification processes, and improving the overall exhaust gas treatment effect.
Benefits: Intermediate treatment, providing conditions for subsequent treatment.
(3) Medical and Health Care Field: Medical waste incineration smoke contains a large amount of bacteria, viruses, dust, and harmful gases. Bag-type dust collectors can effectively remove these pollutants, especially the ultrafine particles smaller than 5μm that are most harmful to the human body, ensuring the health of the surrounding environment and people.
Benefits: Precise purification, ensuring people’s health.
3. Other Fields
(1) Power Industry: In the process of thermal power generation, coal-fired boilers will produce a large amount of fly ash dust. Bag-type dust collectors can purify the boiler smoke, reduce dust emissions, improve power generation efficiency, and reduce pollution to the atmospheric environment.
Benefits: Reducing dust emissions, reducing environmental pollution.
(2) Transportation Industry: During cargo handling at ports and docks, as well as in road construction and concrete mixing stations, a large amount of dust will be generated. Bag-type dust collectors can be installed in these places to collect and treat the dust, reducing the impact on the surrounding environment and traffic.
Benefits: Reducing environmental pollution.
(3) Electronics Industry: In the processes of lithography, etching, and coating in electronic production, a small amount of dust and organic exhaust gas will be generated. Bag-type dust collectors can use highly efficient filter materials to precisely filter dust, ensuring the cleanliness of the production environment and improving the quality of electronic products.
Benefits: Ensuring environmental cleanliness and enhancing product quality.
