Jun 07, 2023 Common Filter Bag Cage Types and Selection

1. Stainless steel bag cage: This bag cage is made by stainless steel. When it comes to stainless steel banding, the three most commonly used grades are: Type 201, type 304 and type 316. Here are 3 typical working conditions where stainless steel bag cages are used: 1.1 High-temperature environments: Stainless steel bag cages are resistant to high temperatures and can withstand the heat generated by industrial processes. They are commonly used in applications such as incinerators, power plants, and metal smelting facilities, where the gas streams may reach elevated temperatures. 1.2 Corrosive or aggressive atmospheres: Stainless steel is highly corrosion-resistant, making it suitable for environments where the gas stream contains corrosive elements, such as acidic gases or chemical fumes. Industries like chemical processing, pharmaceuticals, and wastewater treatment often require the use of stainless steel bag cages to withstand these harsh conditions. 1.3 Heavy-duty industrial applications: Stainless steel bag cages are employed in heavy-duty industries like mining, cement production, and steel manufacturing, where the gas streams carry large amounts of dust and particulate matter. The robust nature of stainless steel allows the bag cages to withstand the abrasive nature of the particles and ensure efficient filtration. Due to its relatively high cost, many customers choose stainless steel skeletons only in special cases. ↓ ↓ ↓ ↓ ↓ Share your Company info. Get latest price list for stainless steel bag cage. 2. Silicone coating bag cage mainly using on working conditions such as: 2.1 Adhesive or sticky dust: Some industrial processes generate dust particles that have adhesive properties, making them stick to surfaces.

May 24, 2023 Baghouse Use High Temperature Filter Media Summary

At present, industrial pollution is the largest source of PM2.5 in China, with cement manufacturing, coal-fired power plants, and steel metallurgy being the 3 major culprits among industrial pollution sources. Therefore, industrial filtering cannot be ignored in the management of PM2.5. Sources of PM2.5 (Source: IPE) However, industrial filtering is not an easy task, because industrial fumes are hot and often contain acidic and alkaline gases, which require high requirements for the technology and materials used for industrial filtering. At present, there are two mainstream technologies for industrial dust removal, namely electrostatic precipitator and bag type precipitator. Based on these two, electric bag composite precipitator is derived. Comparison of Economic Performance of Three Dust Collector Technologies Bag Filter - The mainstream technology for industrial dust control: Currently, electrostatic precipitator technology in China has reached the stage of mature application, bag filter technology is in a period of rapid development. However, as the national requirements for controlling industrial flue gas pollution continue to improve, electrostatic precipitator technology alone cannot fully meet the requirements. The use of bag filter technology and electrostatic bag composite dust collectors as replacements for electrostatic precipitator technology has become mainstream. Mechanism of bag filters: Special fibers are used to make filter bags, and the dusty gas is injected into the bags, where the dust is filtered and captured. The filtering effect depends on the quality of the filter bags. Structure of Bag Filter (Source: Hitachi Plant Construction, Ltd. 56 ) You can also directly consult our sales engineers for free consultation services regarding your dust collection and denitrification projects. ↓ ↓ ↓ ↓ ↓ Contact us now! High temperature Filter Material - The core material of bag filters The filtering effect of bag filters is achieved through filtering materials. Different filtering effects can be achieved by equipping various types of filter bags with different properties, such as resistance to normal temperature(<130℃), resistance to high temperature(>130℃), corrosion resistance, water and oil repellent, fire and explosion prevention, and long service life (2-4 years). The changes and innovations in bag filter technology are closely related to the transformation of filter materials. Currently, the main high-temperature filter fibers used for flue gas treatment domestically and internationally include PPS (polyphenylene sulfide), Nomex (aromatic polyamide), P84 (polyimide), PTFE (polytetrafluoroethylene), glass fibers, and PSA (polyphenylene sulfone) fibers. In practical applications, multiple fibers are often used in combination. Production processes include needle punching, surface coating, emulsion impregnation, etc., which can achieve surface filtration and gradient filtration effects. This not only improves the dust ...
